Description
本発明は、屋根の棟部に施工され、屋根裏への雨水浸入防止等に使用される屋根の防水部材に関するものである。 The present invention relates to a waterproofing member for a roof that is constructed in a roof ridge and used for preventing rainwater from entering the attic.
瓦屋根での棟部に対し古くから行われている防水対策は、棟土やしっくい等を棟頂部に盛り、さらに棟瓦を葺く工法があった。これにより、防水対策はもちろんのこと、いわゆる面戸の部分の仕上がりがきれいになり屋根全体の意匠面に優れるといった効果があった。しかし、棟土やしっくいは、施工中に屋根の棟部以外のところを汚しやすいことや、施工後に棟土内の水分がなくなり乾燥、収縮してもろくなった箇所が剥がれ落ちること等の問題があり、防水部材として完全なものではなかった。また、重量もかなりあるため、軽量化の検討が多く行われていた。 The waterproofing measures that have been applied to the ridges with tiled roofs have long been built by placing ridges and plaster on the top of the ridges, and then spreading the ridge tiles. As a result, not only waterproofing measures but also the so-called face door finish is beautiful and the design of the entire roof is excellent. However, ridges and plasters are prone to soiling other than the ridges of the roof during construction, and the moisture in the ridges will disappear after construction, and the parts that have become brittle after peeling or shrinking will peel off. Yes, it was not perfect as a waterproof member. In addition, because of its considerable weight, many studies have been made to reduce the weight.
近年、屋根の軽量化が進み、屋根の棟部の施工においてはいわゆる乾式工法化が普及しつつある。乾式工法の例として、しっくい等に取って代わって棟際の屋根材間を覆う止水性能を備えたシート状のものが使用されている。特許文献1記載の発明によると、図12に示すように中央のストリップ50が、空気を通過させることができるとともに水をはじくことができる不織材料51と、金属材料を埋め込んだ柔らかくて伸ばすことのできるポリイソブチレンシート材52とで構成されて、長さ方向、幅方向とも伸縮性を有した封止ストリップ5がある。 In recent years, the weight of roofs has been reduced, and so-called dry construction methods are becoming popular in the construction of roof ridges. As an example of the dry construction method, a sheet-like material having a water-stopping performance for covering between roof materials in place of plaster is used. According to the invention described in Patent Document 1, as shown in FIG. 12, the central strip 50 has a non-woven material 51 that allows air to pass through and repels water, and a soft and stretched metal material embedded therein. There is a sealing strip 5 that is made of a polyisobutylene sheet material 52 that can be formed and has elasticity in both the length direction and the width direction.
この構成により、屋根の棟部にかかる屋根瓦にブチルゴム等が密着され雨水の浸入を防ぐとともに、棟部の通気を確保できるという効果を発揮する。 With this configuration, butyl rubber or the like is in close contact with the roof tiles on the roof ridge, preventing rainwater from entering, and ensuring the ventilation of the ridge.
また、特許文献2記載の発明にも同様の構成の屋根用防水部材がある。この発明によると、図13に示すように耐引き裂き性と熱収縮性を有するエラストマーシートを、粘着剤を用いてアルミ箔の表面側に貼り合わせ、該アルミ箔の裏面側に、樹脂系塗料をコーティングした多層防水シート7がある。 The invention described in Patent Document 2 also has a roof waterproof member having a similar configuration. According to this invention, as shown in FIG. 13, the tear-resistant and heat-shrinkable elastomer sheet is bonded to the front surface side of the aluminum foil using an adhesive, and the resin coating is applied to the back surface side of the aluminum foil. There is a coated multilayer tarpaulin 7.
この構成により、様々な意匠の屋根材や屋根勾配が類型的に存在する建築物において、屋根の棟や壁際への防水シートの設置を現場設置形状に適合させられるので、容易に施工できるとともに汎用性に優れる。 With this configuration, the installation of waterproof sheets on roof ridges and walls can be adapted to the site installation shape in buildings with various types of roof materials and roof gradients, which makes it easy to construct and general-purpose. Excellent in properties.
しかしながら、上記特許文献1及び特許文献2に記載された発明には、さらに改良の余地があった。屋根用防水部材を施工しようとするときは、渦巻き状に巻かれた初期状態の屋根用防水部材を棟垂木の長手方向に渡して施工するが、棟垂木との接地部分には接着機能や固定機能がないため、通気部の中心を棟垂木の中心と合わせながらタッカー等を用いステープル針状のもので通気部と棟垂木とを固定しながら施工する必要があった。 However, the inventions described in Patent Document 1 and Patent Document 2 have room for further improvement. When trying to construct a waterproofing member for roofing, install the waterproofing member for the roof in the initial state wound in a spiral shape in the longitudinal direction of the ridge rafter, but it can be bonded to the grounding part of the ridge rafter and fixed Since there is no function, it was necessary to work while fixing the ventilation part and the ridge rafter with a staple needle using a tucker or the like while aligning the center of the ventilation part with the center of the ridge rafter.
この方法により屋根用防水部材は施工できるが、その一方で、通気部と棟垂木との固定時に使用したステープル針状のものが通気部に穴を開けてしまう。さらに、上方に施工する棟瓦を棟垂木に固定するためのねじでも通気部に穴が開き、ねじ穴を介して前記のねじ等から浸入した雨水等が通気部に開いた穴を経由して棟垂木を濡らし、さらに内部の開口まで浸入してしまう。結果として、雨漏れを起こす原因となる恐れがあった。別の問題点として、前記ステープル針状のもので固定するのは棟垂木方向に一定の間隔をあけて行うことが一般的であるため、周囲が固定されていない部位の屋根用防水部材に対し棟瓦を棟垂木に固定しようとすると、ねじの回転作用により屋根用防水部材を上方へ巻き上げてしまう。これは、ねじの先端が屋根用防水部材を貫通するタイミングと棟垂木に螺入されるタイミングとの差がわずかに発生し、屋根用防水部材を貫通してから棟垂木に螺入し始めるまでの時間分、屋根用防水部材が回転しているねじの上方へ引き寄せられるからである。この状態は、屋根用防水部材の防水層を破ってしまい、棟垂木に対してしっかり施工されていない状態となる問題があった。 Although the waterproofing member for roof can be constructed by this method, on the other hand, the staple-like one used when fixing the ventilation part and the ridge rafters opens a hole in the ventilation part. In addition, a screw for fixing the ridge tile to be installed on the ridge rafter also has a hole in the ventilation part, and rainwater that has entered from the screw etc. through the screw hole passes through the hole opened in the ventilation part. Wet the rafters and infiltrate the internal openings. As a result, there was a risk of causing rain leakage. As another problem, since fixing with the staple needle-like one is generally performed at a certain interval in the direction of the ridge rafter, the waterproofing member for the roof of the part where the periphery is not fixed is used. If it is going to fix a ridge tile to a ridge rafter, the waterproofing member for roofs will be rolled up by the rotation effect | action of a screw. This is because there is a slight difference between the timing when the tip of the screw penetrates the roof waterproofing member and the timing when it is screwed into the ridge rafter, until the screw starts penetrating through the roof waterproofing member This is because the waterproofing member for roof is attracted to the upper side of the rotating screw for this time. This state has a problem that the waterproof layer of the waterproofing member for roof is broken, and the construction is not firmly applied to the ridge rafter.
別の課題として、この類の屋根用防水部材は、棟垂木に対し左右が均等になって初めて高い意匠性、高い防水性能を達成できるが、屋根用防水部材の中心と棟垂木の中心とをうまく合わせて施工することは、特に長尺になるほど困難であった。 As another issue, this kind of waterproofing member for roofs can achieve high design and high waterproofing performance only when the right and left sides are even with respect to the ridge rafters. It was particularly difficult to construct properly, as the length became longer.
以上のことをかんがみ、本発明の課題は、屋根用防水部材において通気部にステープル針等の固定具を使用することなく棟垂木に固定でき、しかも雨漏れの恐れを皆無にできる屋根用防水部材を提供することにある。 In view of the above, the object of the present invention is to provide a waterproofing member for roofs that can be fixed to a ridge rafter without using a fixing tool such as a staple needle in the ventilation part of the waterproofing member for roofs, and can eliminate any risk of rain leakage. Is to provide.
上記の課題を解決するために、本発明の屋根用防水部材は、施工前に渦巻き状に巻かれ、施工時には長さ方向及び/又は幅方向に伸縮可能な構造で長尺物として屋根の棟部に施工される屋根用防水部材であって、幅方向の両側部に粘着層を有する屋根用防水部材において、前記屋根用防水部材の棟垂木との当接面に止水性粘着面を備えた構成を採用する。 In order to solve the above-described problems, the waterproof member for roof according to the present invention is wound in a spiral shape before construction, and can be expanded and contracted in the length direction and / or width direction at the time of construction. A waterproofing member for a roof constructed in a part, wherein the waterproofing member for a roof has an adhesive layer on both sides in the width direction, and a waterproofing adhesive surface is provided on a contact surface of the roofing waterproofing member with a ridge rafter. Adopt the configuration.
上記の構成を採用することにより、棟垂木と屋根用防水部材とを固定する際に、タッカー等の工具を用いなくても難なく施工できる。また、棟瓦を棟垂木に固定する場合において、ねじにより屋根用防水部材を突き破ってしまっても、前記止水性接着面により屋根用防水部材の突き破られた穴からの水の浸入を防止することができる。 By employ | adopting said structure, when fixing a ridge rafter and the waterproofing member for roofs, it can construct without difficulty, without using tools, such as a tucker. In addition, when fixing the roof tile to the roof rafter, even if the roof waterproof member is pierced by a screw, the water-proof adhesive surface prevents water from entering from the hole through which the roof waterproof member has been pierced. Can do.
また、上記の発明をより効果的に発揮するために、前記屋根用防水部材の最も上層に形成される前記不織布層の表面側に、長手方向にわたって伸びる中心線15もしくは棟垂木33の幅と対応する施工基準線16が少なくとも1本以上設けられている構成を採用する。この構成の採用により、従来では棟芯方向に対し左右にきれいに合わせるのが困難であった屋根用防水部材が、施工基準線を参考に棟垂木への中心合わせを容易に行うことができるので、手間がかからない。当然、中心線も設けていればなおさらのことである。 Moreover, in order to demonstrate said invention more effectively, it respond | corresponds with the width | variety of the center line 15 extended over a longitudinal direction, or the ridge rafter 33 on the surface side of the said nonwoven fabric layer formed in the uppermost layer of the said waterproofing member for roofs A configuration in which at least one construction reference line 16 is provided is adopted. By adopting this configuration, the waterproofing member for roofs, which was difficult to adjust to the right and left in the ridgeline direction in the past, can be easily centered on the ridge rafter with reference to the construction reference line. It does not take time and effort. Of course, even more so if you have a centerline.
本発明の屋根用防水部材により、タッカー等の工具類を不要として屋根用防水部材を棟垂木に固定できるうえ、その固定作業が迅速に行えるようになる。さらには、棟瓦の棟垂木への固定時にねじ等が屋根用防水部材を突き破っても、棟瓦の内部空間に浸入した雨水等が浸入することなく、より高い防水性能を発揮することができる。そして、施工基準線により屋根用防水部材が棟垂木に対しバランスよく施工できるので、施工精度が高く、作業の効率化が図られる。 The roof waterproof member of the present invention makes it possible to fix the roof waterproof member to the ridge rafter without using tools such as a tucker, and to quickly fix the roof waterproof member. Furthermore, even when screws or the like break through the roof waterproofing member when the ridge tile is fixed to the ridge rafter, rainwater or the like that has entered the interior space of the ridge tile does not enter, and higher waterproof performance can be exhibited. And since the waterproofing member for roofs can be constructed with good balance with respect to the ridge rafter by the construction reference line, the construction accuracy is high and the work efficiency is improved.
以下、本発明における実施例について詳細に述べる。 Examples of the present invention will be described in detail below.
[基本構成]
まず、本発明の屋根用防水部材1の基本構成について説明する。本発明の屋根用防水部材1は、図1や図2、図5に示すように、主に不織布層10、防水基材層11、金属膜層12、粘着層13、剥離紙14の5層より構成されている。
[Basic configuration]
First, the basic configuration of the waterproofing member 1 for roof according to the present invention will be described. As shown in FIGS. 1, 2, and 5, the roof waterproof member 1 of the present invention is mainly composed of a nonwoven fabric layer 10, a waterproof base material layer 11, a metal film layer 12, an adhesive layer 13, and a release paper 14. It is made up of.
本発明の屋根用防水部材1の基本形状は、従来技術にもあるように、一方に長尺で帯状となっており、通常状態(施工前の状態)で渦巻き状に巻き取られている。また、断面視は全体的に薄膜状であるが、幅方向中心部と両端縁との略中央部付近に、両端縁から中心部に向かって上方にZ字状あるいは逆Z字状に折り返しが設けられている。この折り返しが幅方向に向かって伸縮可能としている。 As in the prior art, the basic shape of the waterproofing member 1 for roofs according to the present invention is long and band-like on one side, and is wound in a spiral shape in a normal state (state before construction). Moreover, although the cross-sectional view is generally a thin film, it is folded back in a Z-shape or an inverted Z-shape upward from both edges toward the center near the center of the width direction center and both edges. Is provided. This turn-back can be expanded and contracted in the width direction.
不織布層10は、屋根用防水部材の最も上層に形成され、一定の幅及び屋根用防水部材の長さと同一程度の長さを有している。不織布層10の材質は、公知の技術に記載された材質を適宜選択するものとし、一例としてポリエチレンやポリプロピレン等の不織布で構成されている。不織布層10は、後述の防水基材層11と一部又は全部が接着されて一体となっており、棟瓦表面等から浸入した雨水等を内部に浸入させないよう、一次防水層として高い防水性、撥水性を有している。この不織布層10は、小屋裏より開口を経由して上昇してくる空気を通気する効果も有する。なお、不織布層10は棟部に設けられた開口に雨水等を浸入させずしかも通気ができるようになっていればよいので、幅方向に全範囲設けられておらず、長手方向の中心線より30〜100mm程度、特に望ましくは50〜80mm程度の範囲で設けられていればよいが、これに限定されず適宜必要な範囲に設けられている。 The nonwoven fabric layer 10 is formed in the uppermost layer of the waterproofing member for roofs, and has a certain width and the same length as the length of the waterproofing member for roofs. The material of the nonwoven fabric layer 10 shall select suitably the material described in the well-known technique, and is comprised by nonwoven fabrics, such as polyethylene and a polypropylene, as an example. The non-woven fabric layer 10 is partly and entirely bonded to a later-described waterproof base material layer 11, and is highly waterproof as a primary waterproof layer so as to prevent rainwater or the like that has entered from the surface of the roof tile from entering the interior. Has water repellency. This nonwoven fabric layer 10 also has an effect of ventilating air rising from the back of the cabin through the opening. In addition, since the nonwoven fabric layer 10 should just be able to ventilate rainwater etc. without infiltrating into the opening provided in the ridge part, the full range is not provided in the width direction, but from the center line of a longitudinal direction. Although it should just be provided in the range of about 30-100 mm, and especially desirably about 50-80 mm, it is not limited to this and is provided in the necessary range as appropriate.
また、不織布層10の別の効果として、図3に示すようなさまざまな識別のための表記10aが描かれるよう一種の印刷面となっており、表記10aには品名や型番、製造年月日のほか、施工手順や施工をする方向の指示等がある。本発明の屋根用防水部材1は、長手方向へ向かって連続した重合部Aを設けていることにより、長手方向がいくらか伸縮可能となっており、複雑な形状の屋根材32の表面であっても容易に馴染ませる(屋根面の形状に沿った形に変形でき、屋根材32との隙間をなくし、しっかりと防水を取る)ことができる。特に、屋根材同士の重なり部分は、例えば粘土瓦の場合、最大で25mm程度の段差が発生することがある。したがって、高い段差があっても重合部Aが長手方向にいくらか伸長する(幅方向で部分的に伸長することを含む)ことにより隙間なく施工できる(例として図9)。これは、段差に限らず屋根材表面が大きく湾曲したものであっても同様である。前記の重合部Aは、一定の向きで構成されていることが良く、一方に対し他方が上から重ねられる様態が繰り返されており、施工時に軒側となる方向が上方から重なるように山折りとなっていることが望ましい。この構成により、万一雨水が屋根用防水部材1に付着した際でも、雨水の流下がスムーズに行われ、わずかながらでも有していた漏水の危険性や屋根用防水部材そのものの腐食を抑制させられる効果が期待できる。これらは、特に隅棟20で顕著であるため、不織布層10には施工方向の表記10aが必要である。 Further, as another effect of the nonwoven fabric layer 10, it is a kind of printed surface such that various notations 10a as shown in FIG. 3 are drawn, and the notation 10a includes a product name, a model number, and a manufacturing date. In addition, there are instructions for the construction procedure and direction of construction. The roof waterproofing member 1 of the present invention is provided with the overlapped portion A continuous in the longitudinal direction, so that the longitudinal direction can be somewhat expanded and contracted, and is a surface of the roof material 32 having a complicated shape. Can be easily adapted (can be transformed into a shape that conforms to the shape of the roof surface, eliminates the gap with the roofing material 32, and is firmly waterproofed). In particular, when the roof material overlaps, for example, in the case of clay tiles, a step of about 25 mm at maximum may occur. Therefore, even if there is a high level difference, the overlapped portion A can be constructed without any gap by extending somewhat in the longitudinal direction (including partially extending in the width direction) (as an example, FIG. 9). This is not limited to the step, and the same applies to the case where the roof material surface is greatly curved. The overlapped portion A is preferably configured in a certain direction, and is repeated in such a manner that one side is overlapped with the other from the top, and the direction of the eave side at the time of construction overlaps from above. It is desirable that With this configuration, even if rainwater adheres to the waterproofing member 1 for roofing, the rainwater can flow smoothly, and even a slight amount of water leaks and corrosion of the waterproofing member for roofing itself can be suppressed. Can be expected. Since these are especially conspicuous in the corner building 20, the nonwoven fabric layer 10 needs the notation 10a of the construction direction.
防水基材層11は、不織布層10の下方に形成され、接着剤によって金属膜層とほぼ一体となっている。防水基材層11は、前記不織布層10と同様、雨水等を小屋裏まで浸入させないよう二次防水層として高い防水性能を有するとともに、金属膜層12の柔軟性と協働して折り曲げ加工性に優れた効果を有する。具体的な材質として、熱可塑性エラストマー等を好適例とする。防水基材層11は、その厚みが0.1mmないし0.5mm程度、特に0.3mm程度を好適とする。防水基材層11は、屋根用防水部材1の幅方向全域に設けられており、不織布層10が上方に被さる範囲においては、金属膜層12とともに通気口12aが幅方向に2列以上、望ましくは4列以上で長さ10センチメートル当たり直径5〜20mm程度の通気口12aが3〜10個程度設けられている。この通気口12aは、棟を構成する野地板間の開口(図示なし)から上昇してきた空気を通気することができるようになっている。また、この通気口12aは、その全範囲が上部に設けた不織布層10で覆われており、屋根用防水部材1の施工状態において棟垂木33の上面と接しないよう、幅方向での中心付近を避けるように配置されている。ここで、重合部Aの長さは、一般長さ(渦巻きを解いた未施工の状態)に対する実長さ(重合部Aをすべて伸ばしきったときの長さ)が110〜150%程度、特に116〜133%程度となるように設けられているので、長手方向に向かって伸縮可能としている。なおまた、重合部Aは、防水基材層と金属膜層が一体になった状態で繰り返し構成されている。 The waterproof base material layer 11 is formed below the nonwoven fabric layer 10 and is substantially integrated with the metal film layer by an adhesive. The waterproof base material layer 11 has a high waterproof performance as a secondary waterproof layer so as to prevent rainwater and the like from entering the back of the hut, similarly to the non-woven fabric layer 10, and bends easily in cooperation with the flexibility of the metal film layer 12. It has an excellent effect. A specific example is a thermoplastic elastomer or the like. The waterproof base material layer 11 preferably has a thickness of about 0.1 mm to 0.5 mm, particularly about 0.3 mm. The waterproof base material layer 11 is provided in the entire width direction of the waterproofing member 1 for roof, and in the range where the nonwoven fabric layer 10 covers upward, the metal film layer 12 and the vent holes 12a are desirably arranged in two or more rows in the width direction. Is provided with about 3 to 10 vents 12a having a diameter of about 5 to 20 mm per 10 centimeters in a length of 4 rows or more. This vent 12a can ventilate the air which has risen from the opening (not shown) between the field boards constituting the ridge. The vent 12a is entirely covered with the nonwoven fabric layer 10 provided on the upper portion, and is near the center in the width direction so as not to contact the upper surface of the ridge rafter 33 in the construction state of the roof waterproofing member 1. Arranged to avoid. Here, as for the length of the superposition | polymerization part A, the actual length (length when all the superposition | polymerization part A is fully extended) with respect to general length (the state of un-construction which unwound the spiral) is about 110-150%, especially Since it is provided to be about 116 to 133%, it can be expanded and contracted in the longitudinal direction. In addition, the overlapping portion A is repeatedly configured in a state where the waterproof base material layer and the metal film layer are integrated.
金属膜層12は、防水基材層11と後述の粘着層13との間に形成されている。金属膜層12の目的は、金属膜が有する可塑性の特徴を利用して、屋根の凹凸面に本発明の屋根用防水部材を施工したときに、屋根の凹凸面に馴染みやすく、しかも形状を保たせるためのものである。金属膜層12は、屋根用防水部材1を手加工で切断でき屋根面に馴染ませられることを考え、30μm〜90μm程度の薄膜状で構成されている。材質は、例として一般的なアルミ箔を用いるが、コスト面や施工性等を考慮して適宜材質を選択される。なお、金属膜層12には前述したように防水基材層11とともに、その同一箇所に通気口12aが設けられていてもよい。 The metal film layer 12 is formed between the waterproof base material layer 11 and an adhesive layer 13 described later. The purpose of the metal film layer 12 is to use the plastic characteristics of the metal film, so that when the waterproofing member for roofs of the present invention is applied to the uneven surface of the roof, the shape of the metal film layer 12 can be easily adjusted to the uneven surface of the roof. It is for putting it on. The metal film layer 12 is formed in a thin film of about 30 μm to 90 μm in consideration of being able to cut the waterproofing member 1 for roof by hand processing and adapting to the roof surface. As a material, a general aluminum foil is used as an example, but a material is appropriately selected in consideration of cost and workability. The metal film layer 12 may be provided with a vent 12a at the same location together with the waterproof base material layer 11 as described above.
また、図示はしないが、金属膜層には、少なくともその下面(屋根材32側)に樹脂コーティングがされており、アルミ箔等の金属に対し耐久性、耐食性を向上させる目的のほか、極端な変形等に対し、金属の膜が容易に裂けないようにする目的がある。前記樹脂コーティングの材質は、エポキシ樹脂系、アミノ樹脂系、メラミン樹脂系等とし、前記樹脂コーティングの厚さは0.5μmないし5μm程度とするが、これらはいずれも周知技術に記載のものを適宜選択すればよい。 Although not shown, the metal film layer has a resin coating on at least the lower surface (the roof material 32 side), and in addition to the purpose of improving durability and corrosion resistance against metals such as aluminum foil, The object is to prevent the metal film from tearing easily against deformation or the like. The material of the resin coating is an epoxy resin type, an amino resin type, a melamine resin type, and the like, and the thickness of the resin coating is about 0.5 μm to 5 μm. Just choose.
粘着層13は、金属膜層12よりも下層に設けられ、棟部の屋根材32に直接接着する部位である。そのため、幅方向の両端部付近に設けられ、屋根材32との接着が十分にでき、しかもその接着面から雨水等が棟の内部まで浸入しないよう防水性に優れていることが求められる。この粘着層13は、例えばブチルゴム等が好適である。屋根材32に対する接着力と防水性を十分に発揮できるよう、例えば粘着層13の幅は、屋根用防水部材1の幅方向に対し10mm〜50mm程度が良く、特に望ましくは30mm程度がよい。また、粘着層13の厚み(高さ)は、少なくとも0.5mm以上が良く、2mm程度の適当な厚さの範囲であれば凹凸の大きい屋根材32に対し十分な接着力が得られる。 The adhesive layer 13 is a part that is provided below the metal film layer 12 and directly adheres to the roof material 32 of the ridge. Therefore, it is required to be provided in the vicinity of both ends in the width direction, to be sufficiently adhered to the roofing material 32, and to be excellent in waterproof properties so that rainwater or the like does not enter the inside of the building from the adhesion surface. The adhesive layer 13 is preferably butyl rubber, for example. For example, the width of the pressure-sensitive adhesive layer 13 is preferably about 10 mm to 50 mm with respect to the width direction of the roof waterproofing member 1 and particularly preferably about 30 mm so that the adhesive strength and waterproofness to the roof material 32 can be sufficiently exhibited. Further, the thickness (height) of the pressure-sensitive adhesive layer 13 is preferably at least 0.5 mm or more, and sufficient adhesive force can be obtained for the roof material 32 having large irregularities if the thickness is within a suitable range of about 2 mm.
剥離紙14は、屋根用防水部材1の最も下層に形成され、前記の粘着層13を覆うためのものである。剥離紙14は、粘着層13とは接着されているが、その用途からして容易に剥離できる剥離性の高い材質で構成されている。前記の粘着層は、接着力を有しているので屋根用防水部材1を施工する際に、想定外の箇所に不意に接着させてしまう可能性が十分考えられる。粘着層13は、材質によって他のものに接着すると剥がしたり取り除いたりするのに労力が必要であるため、屋根用防水部材1の施工前には粘着層13を覆った状態であり、施工する際に必要に応じて容易にはがせるよう剥離紙14を設ける。剥離紙14は、粘着層13から容易に剥離させることができるよう、その幅方向よりも若干幅広であり、長さ方向よりも若干長くなって指でつまみやすくなっている構成とすることが望ましい。 The release paper 14 is formed in the lowermost layer of the waterproofing member 1 for roof and covers the adhesive layer 13. The release paper 14 is bonded to the pressure-sensitive adhesive layer 13 but is made of a highly peelable material that can be easily peeled depending on its use. Since the said adhesion layer has adhesive force, when constructing the waterproofing member 1 for roofs, possibility of making it adhere unexpectedly to a location unexpectedly is considered sufficiently. The adhesive layer 13 is in a state of covering the adhesive layer 13 before construction of the waterproofing member 1 for roofing, since it takes labor to peel off or remove the adhesive layer 13 when it is adhered to another material. A release paper 14 is provided so that it can be easily peeled off if necessary. Desirably, the release paper 14 is slightly wider than the width direction and slightly longer than the length direction so that it can be easily peeled off from the adhesive layer 13 so that it can be easily pinched with a finger. .
以上までで、本発明の屋根用防水部材1の基本構成を説明したが、これらは公知技術等で容易に構成されるものである。本発明の特徴は、屋根用防水部材1のうち屋根の棟部に施工された棟垂木33との当接面に止水性接着面13aを備えたこと、及び不織布層10に中心線15とは別の施工基準線16が設けられていることの二つの点で特徴がある。これらの点について以下に詳述する。 The basic configuration of the waterproofing member for roof 1 according to the present invention has been described above, but these are easily configured by a known technique or the like. A feature of the present invention is that the waterproof surface 1 is provided with a waterproofing adhesive surface 13a on the contact surface with the ridge rafter 33 constructed in the roof ridge portion of the waterproofing member 1 for the roof, and the center line 15 on the nonwoven fabric layer 10 There are two features in that another construction reference line 16 is provided. These points will be described in detail below.
[止水性接着面の構成]
第一に、本発明の止水性粘着面13aは、図1、図3、図4、図5に示すように従来の他の屋根用防水部材と比べ、さらに幅方向の略中央部に、長手方向にわたって帯状に設けられている点で相違している。この部分の止水性粘着面13aは、屋根用防水部材1が棟部に施工された際にちょうど棟垂木33の上面に位置しており、棟垂木33への接着力によって前後左右にずれないという効果がある。また、屋根用防水部材1の棟垂木33への固定を止水性粘着面13aで行うので、タッカー等の工具を用いてステープル針等で固定する必要がない。さらには、棟垂木の上面が止水性粘着面13aで覆われているため、棟瓦35をねじ34により棟垂木33に固定する際、屋根用防水部材1の不織布層10、防水基材層11、金属膜層12を貫通しても、止水性粘着面13aが高い止水性を発揮するため棟部から雨水等を浸入させることがない。要は、本発明の屋根用防水部材1の粘着層13及び止水性粘着面13aが幅方向中央部及び両端部の計3条設けられており、中央部の止水性粘着面13aは棟垂木33の上面に接着させて屋根用防水部材1の固定を図るとともに棟瓦35の固定によりねじ34が貫通しても雨水の浸入を防ぐことができ、幅方向両端の粘着層13には屋根材32の表面と接着させてその表面からの雨水の浸入を防止することができる。
[Configuration of water-resistant adhesive surface]
First, as shown in FIGS. 1, 3, 4, and 5, the water-stopping adhesive surface 13a of the present invention has a longer longitudinal center than the other conventional waterproofing members for roofs. It is different in that it is provided in a strip shape over the direction. The waterproofing adhesive surface 13a of this part is located on the upper surface of the ridge rafter 33 when the waterproofing member 1 for roof is constructed on the ridge, and is not displaced from front to back and left and right by the adhesive force to the ridge rafter 33. effective. Further, since the roof waterproofing member 1 is fixed to the ridge rafter 33 by the water-proof adhesive surface 13a, it is not necessary to fix the roof waterproof member 1 with a staple such as a tucker. Furthermore, since the upper surface of the ridge rafter is covered with the waterproofing adhesive surface 13a, when the ridge tile 35 is fixed to the ridge rafter 33 with the screw 34, the nonwoven fabric layer 10 of the roof waterproofing member 1, the waterproof base material layer 11, Even if it penetrates the metal film layer 12, the water-stopping adhesive surface 13a exhibits a high water-stopping property so that rainwater or the like does not enter from the ridge. In short, the adhesive layer 13 and the waterproofing adhesive surface 13a of the waterproofing member 1 for roof of the present invention are provided in a total of three strips at the center and both ends in the width direction, and the waterproofing adhesive surface 13a at the center is the mushroom 33. The roof waterproofing member 1 can be fixed by adhering to the upper surface of the roof, and rainwater can be prevented from entering even if the screws 34 penetrate by fixing the roof tile 35. It can be adhered to the surface to prevent rainwater from entering from the surface.
本発明の止水性粘着面13aの基本構成は、図3や図4に示すように、屋根用防水部材1の幅方向の中心より長さ方向にわたって帯状に設けられている。止水性粘着面13aの幅は、20〜50mm程度が良く、特に30〜45mmであることが望ましい。この幅は、棟部に施工される棟垂木33の上面の幅と略一致する程度としているが、実質は少なくとも棟瓦35の固定時において棟垂木33へねじが固定される位置に止水性粘着面13aがあれば足りるため、幅は棟垂木33の幅に対し幅狭になっていても良く、棟垂木33の幅方向の略中央部にいくらか幅を有していれば良い。また、止水性粘着面13aの材質は、例えば粘着層と同様にブチルゴム等で構成されていても良い。つまり、止水性粘着面13aは、棟垂木33と接着して十分に固定できる機能と、雨水等に対する防水機能とを有していることが望ましい。また、これらの機能を有することで、棟瓦35を固定するねじ34を屋根用防水部材1に貫通させて棟垂木33に螺入する工程でも、止水性粘着面13aにより屋根用防水部材1が棟垂木33に対し連続して接着されているので、その接着強度は十分有しており、ねじ34の回転動作による屋根用防水部材1の巻き上げは発生しない。 As shown in FIGS. 3 and 4, the basic structure of the water-stopping adhesive surface 13 a of the present invention is provided in a band shape from the center in the width direction of the waterproofing member 1 for roofs in the length direction. The width of the water-stop adhesive surface 13a is preferably about 20 to 50 mm, and particularly preferably 30 to 45 mm. This width is set to substantially coincide with the width of the upper surface of the ridge rafter 33 to be constructed in the ridge, but the water-stopping adhesive surface is substantially at a position where the screw is fixed to the ridge rafter 33 at least when the ridge tile 35 is fixed. Since 13a is sufficient, the width may be narrower than the width of the ridge rafter 33, and it is only necessary to have some width at a substantially central portion in the width direction of the ridge rafter 33. Moreover, the material of the water-stop adhesive surface 13a may be comprised, for example with butyl rubber etc. similarly to the adhesion layer. That is, it is desirable that the water-stopping adhesive surface 13a has a function that can be sufficiently bonded and fixed to the ridge rafter 33 and a waterproof function against rainwater or the like. Moreover, by having these functions, the waterproofing member 1 for roof can be constructed by the waterproofing adhesive surface 13a even in the step of passing the screw 34 for fixing the roof tile 35 through the waterproofing member 1 for roof and screwing it into the rafter 33. Since it is continuously bonded to the rafters 33, it has sufficient adhesive strength, and the roof waterproofing member 1 is not wound up by the rotating operation of the screws 34.
さらに、本発明の止水性粘着面13aは、そのほぼ全面が剥離紙14で覆われている。この剥離紙14により、止水性粘着面13aが不意に屋根面や屋根材32に付着してしまったとしても、それらの箇所に引っ付いたり汚したりしてしまうことはない。この剥離紙14は、前記止水性粘着面13aの幅と同一か、同幅よりも若干幅広となっており、又は、止水性粘着面13aの長さ方向に対して同一長さか、同一長さよりも若干長くなっている。これにより、屋根用防水部材1の施工時に剥離紙14を剥がしやすくできる。要は、止水性粘着面13aは、粘着層13と同様の性質を有しており、屋根用防水部材1に対する配置が異なっている。 Furthermore, almost the entire surface of the water-stopping adhesive surface 13 a of the present invention is covered with the release paper 14. Even if the waterproofing adhesive surface 13a is unexpectedly attached to the roof surface or the roofing material 32 by this release paper 14, it will not be caught or soiled at those locations. The release paper 14 is the same as or slightly wider than the width of the water-stopping adhesive surface 13a, or the same length or the same length with respect to the length direction of the water-stopping adhesive surface 13a. Is also slightly longer. Thereby, the release paper 14 can be easily peeled off when the waterproofing member 1 for roof is constructed. In short, the water-stopping adhesive surface 13a has the same properties as the adhesive layer 13, and the arrangement with respect to the waterproofing member for roof 1 is different.
ここで、図6に示すように、屋根用防水部材1を渦巻き状に巻き取った状態で、止水性粘着面13aと接する不織布層10が剥離性を有している材料としたときに、前記の止水性粘着面13aが屋根用防水部材1そのものの別の部位に接着してしまわないよう、剥離紙14に取って代わって、屋根用防水部材1を渦巻き状にしたときに止水性粘着面13aと接する部位の不織布層10又は不織布層よりもさらに上層に設ける層を剥離性のある剥離層14aとする構成も可能である。この態様であれば、止水性粘着面13aに剥離紙14を貼り付けなくても屋根用防水部材1そのものを汚すことはなく、剥離紙14を剥がす手間がないのですぐに施工することができ、しかも施工現場での剥離紙14の廃棄物を発生させることがない。屋根用防水部材1を渦巻き状に保管した状態を考慮すると、渦巻き状に巻かれた屋根用防水部材1の最も外側の円周分程度の長さだけ剥離紙14が貼り付けられていてもよい。 Here, as shown in FIG. 6, when the nonwoven fabric layer 10 in contact with the water-stopping adhesive surface 13 a is made of a peelable material in a state in which the waterproofing member 1 for a roof is wound in a spiral shape, The waterproofing adhesive surface when the waterproofing member 1 for the roof is made into a spiral instead of the release paper 14 so that the waterproofing adhesive surface 13a of the waterproofing material is not adhered to another part of the waterproofing member 1 for the roof itself. The structure which makes the layer provided in the upper layer further from the nonwoven fabric layer 10 of the site | part in contact with 13a or a nonwoven fabric layer as the peeling layer 14a with peelability is also possible. If it is this aspect, the waterproofing member for roof 1 itself will not be soiled without attaching the release paper 14 to the water-stopping adhesive surface 13a, and it can be applied immediately because there is no time to peel off the release paper 14. Moreover, the waste of the release paper 14 at the construction site is not generated. In consideration of the state in which the roof waterproof member 1 is stored in a spiral shape, the release paper 14 may be pasted for a length of the outermost circumference of the roof waterproof member 1 wound in a spiral shape. .
[施工基準線の構成]
第二に、本発明は、屋根用防水部材1の不織布層10の表面側に中心線15及び棟垂木33の幅と対応する施工基準線16が設けられていることでも、従来技術とは異なる特長がある。つまり、従来の技術では、屋根用防水部材1の中心に中心線15だけが設けられていることが多く、その中心線15を棟芯とあわせることで左右のバランスを整えていたが、実際の施工作業においては棟芯と中心線15とを一致させることは難しいという問題点があった。そこで、本発明では棟垂木33の幅と対応する施工基準線16を設けることで、この問題点の解消を図った。
[Configuration of construction reference line]
Secondly, the present invention is also different from the prior art in that the construction reference line 16 corresponding to the width of the center line 15 and the ridge rafter 33 is provided on the surface side of the nonwoven fabric layer 10 of the waterproofing member 1 for roof. There are features. That is, in the prior art, only the center line 15 is often provided at the center of the waterproofing member 1 for the roof, and the center line 15 is aligned with the ridge core to adjust the left and right balance. In the construction work, there is a problem that it is difficult to match the ridge core and the center line 15. Accordingly, in the present invention, the construction reference line 16 corresponding to the width of the ridge rafter 33 is provided to solve this problem.
本発明の施工基準線16は、既存技術である屋根用防水部材表面側の長さ方向の中心に、施工の目安として中心線15とは別の施工基準線16を設けている。図3、図5、図7に示すように、施工基準線16は、棟芯方向に対し少なくとも左右に1本ずつ、望ましくは2〜3本ずつが中心線15から同一間隔で設けられており、2本の施工基準線16の間隔は上記した棟垂木33の幅と対応している。例として、棟垂木33の上面の幅が42mmの場合、中心線15から左右それぞれの施工基準線16までの間隔は21mmがよく、施工基準線16と棟垂木33の上面の縁とが同一線上に位置していることが望ましい。この様態により、屋根用防水部材1を施工し始める際に、中心線15を棟垂木33の略中央に合わせ、もしくは棟垂木33上面の一方の縁に合わせ、施工基準線16を棟垂木33の上面の縁(他方の縁)に合わせて施工すれば、少なくとも2本の線(2点)を基準として屋根用防水部材1を棟部に施工することができるため、上記により中心線15を不要としても施工可能であるし、屋根用防水部材1の施工精度が向上し位置合わせも容易に行えるようになる。 The construction reference line 16 of the present invention is provided with a construction reference line 16 different from the center line 15 as a guide for construction at the center in the length direction on the surface side of the waterproofing member for roofs, which is an existing technology. As shown in FIGS. 3, 5, and 7, the construction reference line 16 is provided at the same interval from the center line 15 at least one, preferably two or three, on the left and right sides with respect to the ridgeline direction. The interval between the two construction reference lines 16 corresponds to the width of the ridge rafter 33 described above. As an example, when the width of the upper surface of the ridge rafter 33 is 42 mm, the distance from the center line 15 to the left and right construction reference lines 16 is preferably 21 mm, and the construction reference line 16 and the upper edge of the ridge rafter 33 are on the same line. It is desirable to be located at. In this manner, when construction of the waterproofing member 1 for the roof is started, the center line 15 is aligned with the approximate center of the ridge rafter 33 or one edge of the top surface of the ridge rafter 33, and the construction reference line 16 is aligned with the ridge rafter 33. If it is constructed according to the edge of the upper surface (the other edge), the roof waterproofing member 1 can be constructed on the ridge with reference to at least two lines (two points). As a result, the construction accuracy of the waterproofing member for roof 1 can be improved and positioning can be easily performed.
また、別の構成として、図4や図6に示すように、止水性粘着面13aの棟垂木33との接着面そのものに、不織布層10に設けた施工基準線16とは別の線(中心線や施工基準線)を設ける。これにより、屋根用防水部材1の作業者が止水性粘着面を棟垂木33に施工する際に、その中心や縁と止水性粘着面に設けた線との位置合わせを常時目で確認しながら施工できるので、施工精度の向上が図られ、かつ施工時間も短縮させることが可能である。 Moreover, as another structure, as shown in FIG.4 and FIG.6, the line (center) different from the construction reference line 16 provided in the nonwoven fabric layer 10 on the adhesion surface itself with the ridge rafter 33 of the water-stopping adhesive surface 13a. Line and construction reference line). Thereby, when the operator of the waterproofing member for roof 1 constructs the water-stopping adhesive surface on the ridge rafter 33, while constantly checking the alignment of the center and the edge with the line provided on the water-stopping adhesive surface, Since construction can be performed, construction accuracy can be improved and construction time can be shortened.
棟垂木33の幅は、屋根の施工現場によりさまざまな寸法が使用されており、その例を挙げても40mm、42mm、45mm等が存在するため、前記した施工基準線16は前記の寸法等を含み棟垂木の幅寸法に合わせて3種類程度設けてもよい。このとき、複数本設けた施工基準線は、棟垂木の幅に大きな差がないことからそれぞれが近接してしまうので、2以上の施工基準線を設けるときは、それぞれの施工基準線が判別しやすいよう線種や線色、線太さ等を変更し、一目で判別できる構成とする。例えば、施工基準線が左右それぞれ3本あるときは、線種で判別する場合、実線、点線、一点鎖線としたり、線色で判別するときは、黒色、白色、赤色としたり(ただし、施工基準線を設けた不織布層の色は除く)、線太さで判別する場合は、0.3mm、0.7mm、1.0mmとしたりする。又は、これら三種の識別要素の組み合わせでも良い。その他、識別可能な方法が最適な手段で選択される。 As for the width of the ridge rafter 33, various dimensions are used depending on the construction site of the roof, and even if examples thereof are 40 mm, 42 mm, 45 mm, etc., the above-mentioned construction reference line 16 has the above-mentioned dimensions and the like. You may provide about three types according to the width dimension of a containing ridge rafter. At this time, since there are no large differences in the width of the ridge rafter, the construction reference lines provided in plurality are close to each other, so when providing two or more construction reference lines, each construction reference line is identified. The line type, line color, line thickness, etc. are changed so that they can be easily determined, and the structure can be distinguished at a glance. For example, when there are three construction reference lines each on the left and right, when distinguishing by line type, solid lines, dotted lines, and alternate long and short dash lines, and when distinguishing by line color, black, white, and red (however, construction standards The color of the nonwoven fabric layer provided with a line is excluded), and when it is determined by the line thickness, it is 0.3 mm, 0.7 mm, or 1.0 mm. Alternatively, a combination of these three types of identification elements may be used. In addition, an identifiable method is selected by an optimum means.
[施工実施例]
実施例として、本発明の屋根用防水部材1を施工する手順について以下に示す。本施工実施例では、大棟が1本、隅棟が4本の最も標準的な寄棟屋根での施工を想定して説明する。
[Example of construction]
As an example, a procedure for constructing the waterproofing member for roof 1 of the present invention will be described below. In this embodiment, the explanation will be given assuming the construction with the most standard dormitory roof with one large building and four corner buildings.
野地板まで施工された屋根面に改質アスファルト又はその他のルーフィングを施工し、瓦を引っ掛けるための瓦桟木を所定ピッチで固定する(ここまでいずれも図示なし)。次に、棟部に棟金具31を棟方向にやはり所定ピッチで固定し、棟金具31に棟垂木33をわたして固定する。続けて、軒先側より屋根材32を施工し、棟際まで施工する。ここまでは、通常の瓦葺き屋根の施工方法と同様である。ここから、本発明の屋根用防水部材1を施工する。 The modified asphalt or other roofing is applied to the roof surface that has been constructed up to the base plate, and the tile piers for hooking the tiles are fixed at a predetermined pitch (all not shown so far). Next, the ridge bracket 31 is fixed to the ridge at a predetermined pitch in the ridge direction, and the ridge rafter 33 is fixed to the ridge bracket 31. Subsequently, the roofing material 32 is constructed from the eaves side and constructed to the ridgeline. Up to this point, the construction method is the same as that for ordinary tiled roofs. From here, the waterproofing member 1 for roof of this invention is constructed.
図8に示すように、施工対象の屋根2に大棟21と隅棟20の両方が存在する場合は、防水面を考慮して隅棟20、大棟21の順に施工していく。まず、棟垂木33の上面にくる幅をあらかじめ測定しておき、又は、屋根用防水部材1を棟垂木33に仮置きしながら、棟垂木33の縁と概ね一致する施工基準線16を確認しておく。また、不織布層10の表記10aを確認しながら、連続した重合部Aの山折り側を軒側、同谷折り側を棟側に向けて施工する方向を確認しておく(施工前の状態は渦巻き状となっており、施工にあたって屋根用防水部材1の端部を引き出すと、引き出す方向は必ず上方に山折り側が重なっているになっている)。次に、本発明の屋根用防水部材1の端部を棟垂木33の端部よりもいくらか軒側にはみ出させて、最も軒側(隅棟施工の場合)の隅棟先端部分を包み込むよう折りたたみながら施工し始めていく(剥離紙は適宜剥がしていく)。隅棟先端部分の施工が完了すれば、続けて中心線15及び/又は施工基準線16に合わせ屋根用防水部材1の剥離紙14を剥がしながら止水性粘着面13aを棟垂木の上面に指圧等で接着させ、続けて粘着層13を棟際の屋根材32の表面に同様にして接着させる(図9)。このとき、屋根材32の表面の凹凸形状や棟瓦35の被さり範囲に合わせて、適宜屋根用防水部材1を長手方向、幅方向に伸縮させて、屋根材32の表面との隙間ができないよう注視して施工する。そして、これを繰り返しながら長手方向の棟側端部まで施工していく。 As shown in FIG. 8, when both the large ridge 21 and the corner ridge 20 exist on the roof 2 to be constructed, the construction is performed in the order of the corner ridge 20 and the large ridge 21 in consideration of the waterproof surface. First, the width on the upper surface of the ridge rafter 33 is measured in advance, or the construction reference line 16 that substantially matches the edge of the ridge rafter 33 is confirmed while the waterproofing member 1 for roof is temporarily placed on the ridge rafter 33. Keep it. In addition, while confirming the notation 10a of the nonwoven fabric layer 10, confirm the direction in which the continuous fold-side of the overlapped part A is directed toward the eave side and the valley-folded side toward the ridge side (the state before construction is It is spiral, and when the end of the roof waterproofing member 1 is pulled out during construction, the direction of pulling out is always overlapped with the mountain fold side). Next, the end of the waterproofing member 1 for roof according to the present invention is somewhat protruded from the eaves side of the end of the ridge rafter 33, and folded so as to wrap around the end of the corner ridge on the most eave side (in the case of corner ridge construction). (The release paper will be removed as appropriate). When the construction of the corner ridge tip is completed, the water-stopping adhesive surface 13a is applied to the upper surface of the ridge rafter while peeling off the release paper 14 of the waterproofing member 1 for the roof in accordance with the center line 15 and / or the construction reference line 16. Then, the adhesive layer 13 is bonded in the same manner to the surface of the roof material 32 at the ridge (FIG. 9). At this time, according to the uneven shape of the surface of the roofing material 32 and the covering range of the roof tile 35, the roof waterproofing member 1 is appropriately expanded and contracted in the longitudinal direction and the widthwise direction so that there is no gap with the surface of the roofing material 32. And then install. And it repeats to this and repeats to the ridge side edge part of a longitudinal direction.
すべての隅棟20において棟頂部22(三ツ又部)まで施工ができたら、大棟21に屋根用防水部材1を施工する。図9に示すように、棟頂部22に隙間ができないよう隅棟20に施工した屋根用防水部材1との取り合いに注意して、隅棟20と同様に棟垂木33及び屋根材表面に施工する。棟部の施工がひと通り完了したら、図10に示すように、棟垂木33上に隅棟止瓦、棟瓦、三ツ又瓦等を施工し、ねじ34等で固定して屋根2の完成となる。なお、屋根用防水部材1は止水性粘着面13aにより棟垂木にしっかり固定されているため、隅棟止瓦、棟瓦、三ツ又瓦等を施工した際に、屋根用防水部材の巻上げは発生しておらず、その仕上がりが十分に達成される。 When the construction has been completed up to the ridge top 22 (three branches) in all the corner ridges 20, the roof waterproofing member 1 is laid on the large ridge 21. As shown in FIG. 9, paying attention to the roof waterproofing member 1 constructed in the corner ridge 20 so that there is no gap in the ridge top 22, it is constructed on the ridge rafter 33 and the roof material surface in the same manner as the corner ridge 20. . When the construction of the ridge is completed, as shown in FIG. 10, a corner ridge roof tile, a ridge tile, a three-piece roof tile, etc. are constructed on the ridge rafter 33 and fixed with screws 34 or the like to complete the roof 2. In addition, since the waterproofing member 1 for roofs is firmly fixed to the ridge rafter by the water-proof adhesive surface 13a, the roof waterproofing member is rolled up when the corner ridge roof tile, the ridge tile, the three-piece roof tile, etc. are constructed. The finish is fully achieved.
本発明の屋根用防水部材1により、施工の手間が簡易となり施工性の向上が図られるとともに、施工基準線16を棟垂木33の縁に合わせるだけであるので、屋根用防水部材1の施工者によるバラツキを抑えることが可能となる。また、図11に示すように、棟垂木33の上面には止水性粘着面13aが施されており、棟瓦35のねじ留めによる屋根用防水部材1(不織布層10)の損傷(穴が開いた状態)があっても止水性に全く問題はない。 The roof waterproofing member 1 according to the present invention simplifies the construction work and improves the workability, and also only aligns the construction reference line 16 with the edge of the ridge rafter 33. It is possible to suppress variations due to. Moreover, as shown in FIG. 11, the waterproofing adhesive surface 13a is given to the upper surface of the ridge rafter 33, and the waterproofing member 1 (nonwoven fabric layer 10) for roofing by screwing the ridge tile 35 is damaged (a hole is opened). There is no problem with water stoppage even if there is a state.
本発明の屋根用防水部材の構造及び施工方法について具体的な説明をしたが、本発明は上記の好例に限定されるものではなく、その根本的技術思想を逸脱しない範囲において適宜変更することができる。例えば、本発明の屋根用防水部材1の重合部Aの重合量を、屋根材32に合わせて最適なものに適宜変更してもよいし、幅方向の伸縮構造をZ字状の折り返しから蛇腹状に変更することも可能である。 The structure and construction method of the waterproof member for roof according to the present invention have been specifically described. However, the present invention is not limited to the above-mentioned preferred examples, and can be appropriately changed without departing from the fundamental technical idea thereof. it can. For example, the polymerization amount of the overlapping portion A of the waterproofing member 1 for a roof according to the present invention may be appropriately changed to an optimum one according to the roofing material 32, and the expansion / contraction structure in the width direction may be changed from a Z-shaped folding to a bellows. It is also possible to change the shape.
本発明は、屋根の棟部に施工する雨水等の浸入を防止する屋根用の防水部材として幅広く活用できる。 INDUSTRIAL APPLICABILITY The present invention can be widely used as a waterproofing member for roofs that prevents intrusion of rainwater or the like to be constructed on a roof ridge.
