Description

本発明は、屋根又は壁等の外囲体を構成する嵌合タイプの建築用板を構造材に固定支持するものであり、外囲体の施工を迅速にできると共に良好な仕上がりにすることができる受金具に関する。 The present invention is to fix and support a fitting type building board constituting an outer enclosure such as a roof or a wall to a structural material, and it is possible to speed up the construction of the outer enclosure and to achieve a good finish. It is related with the receiving bracket which can be performed.

従来、ビル,工場,住宅或いはその他多くの建築物において、屋根又は壁等の外囲体を施工するために金属製の建築用板が使用されている。その建築用板にも種々のものが存在し、幅方向両側に山形部を有するタイプの建築用板がある。山形部の上部の幅方向両側には膨出する嵌合部が形成されている。そして、隣接する前記建築用板の山形部同士の重合しつつ嵌合固定し、隣接する建築用板同士を連結して屋根、又は壁等の外囲体を施工するものである。 Conventionally, a metal building board is used to construct an enclosure such as a roof or a wall in a building, factory, house or many other buildings. There are various types of building boards, and there is a type of building board having angle portions on both sides in the width direction. Engaging fitting portions are formed on both sides in the width direction of the upper portion of the chevron. Then, the mountain-shaped portions of the adjacent building boards are fitted and fixed while overlapping, and the adjacent building boards are connected to each other to construct an enclosure such as a roof or a wall.

この嵌合タイプの建築用板は、いわゆるボルトレスタイプであり、隣接する建築用板同士の連結においてボルト・ナット或いはビス等の固着具を不用としたものである。これらの嵌合タイプの建築用板を母屋，胴縁等の構造材に固定するために、受金具が使用される。この受金具は、嵌合タイプの建築用板に対して嵌合によって固定することができるものが使用され、前述したようにボルト・ナット或いはビス等の固着具を不用としたものである。この種の受金具には、嵌合タイプの建築用板の山形部裏面側に配置されて、前記膨出部の裏面側より受金具の爪（係止片）が嵌合して、該受金具と建築用板とが嵌合による連結固定ができるようになっている。そしてこの種の受金具は、下記特許文献１に開示されている。
特開平１−２８０１５１号 This fitting type building board is a so-called boltless type, and does not require a fixing tool such as a bolt, a nut, or a screw in the connection between adjacent building boards. In order to fix these fitting-type building boards to structural materials such as purlins and trunk edges, receiving brackets are used. As this receiving metal fitting, one that can be fixed by fitting to a fitting type building board is used, and as described above, a fixing tool such as a bolt, a nut, or a screw is unnecessary. This type of bracket is disposed on the back side of the chevron portion of the fitting type building board, and the claws (locking pieces) of the bracket are fitted from the back side of the bulging portion. The metal fitting and the building board can be connected and fixed by fitting. This type of bracket is disclosed in Patent Document 1 below.
JP-A-1-280151

特許文献１に開示されている受金具の構造を図７及び図８にて概略すると、受金具ａにはその上端に略方形状の頂部ｂが形成されており、該頂部ｂの４個の角箇所から爪ｃ（係止片）が前後方向における外方に突出するようにして形成されている〔図７（Ａ）,（Ｂ）参照〕。これら４個の爪ｃ（係止片）が建築用板ｄ（屋根板）の被係合部に係合し、受金具ａによって建築用板ｄが構造材上に固定されるものである。 7 and 8, the structure of the receiving bracket disclosed in Patent Document 1 is schematically illustrated. The receiving bracket a is formed with a substantially rectangular top b at the upper end thereof, and the four tops b are formed. A claw c (locking piece) is formed so as to protrude outward in the front-rear direction from the corner (see FIGS. 7A and 7B). These four claws c (locking pieces) are engaged with the engaged portions of the building board d (roof board), and the building board d is fixed on the structural material by the metal fittings a.

このような構成としたことにより、前記爪ｃ（係止片）が嵌合作業の過程において、前記建築用板ｄの被係合部eに対して食い込み、爪ｃによる４点箇所の点接合の状態となって、その接合箇所ｆに略集中的に荷重がかかることになる〔図７（Ｃ）参照〕。これによって、前記受金具ａと前記建築用板ｄとは、極めて強固な固定にできる。 By adopting such a configuration, the claw c (locking piece) bites into the engaged portion e of the building board d in the process of fitting work, and the four points are joined by the claw c. In this state, a load is applied substantially intensively to the joint point f (see FIG. 7C). Thereby, the receiving metal fitting a and the building plate d can be fixed extremely firmly.

しかし、施工時における作業員の建築用板ｄを受金具ａに嵌合固定する作業過程において、前記係止片ｃが受金具の頂部ｂから外方に突出しているために、建築用板ｄを受金具ａに向かって押し付けて嵌合させるときに、図７（Ｃ）に示すように、受金具ａの幅方向の中心位置ｊと、建築用板ｄの山形部の幅方向中心位置ｋが僅かにずれてしまった場合には、受金具の幅方向の一方側の爪ｃが建築用板ｄの内面側に強く当接して擦れ合い、爪ｃ（係止片）により建築用板ｄの内方から外方に突出し、変形する傷痕ｇが建築用板ｄに発生することがある〔図７（Ｃ）,（Ｄ）及び図８参照〕。 However, in the process of fitting and fixing the building plate d of the worker to the metal fitting a at the time of construction, since the locking piece c protrudes outward from the top b of the metal fitting, the building plate d Is pressed toward the receiving bracket a and fitted together, as shown in FIG. 7C, the center position j in the width direction of the receiving bracket a and the center position k in the width direction of the chevron of the building board d. Is slightly displaced, the claw c on one side in the width direction of the metal fitting strongly contacts and rubs against the inner surface side of the building board d, and the building board d by the claw c (locking piece). Scratches g that protrude outward from the inside and deform and may be generated on the building board d (see FIGS. 7C, 7D, and 8).

この傷痕ｇは、その大きさ或いは傷の範囲によって、比較的目立つこともあり、屋根,壁等の外囲体の外観を損なうことがあった。そこで、本発明が解決しようとする目的（技術的課題）は、前述したように、受金具と建築用板との係合による接合箇所に変形痕が生じないようにして、しかも簡易且つ迅速に外囲体の施工ができるようにすることにある。 The scar g may be relatively conspicuous depending on the size or the range of the scratch, and may impair the appearance of an outer enclosure such as a roof or a wall. Therefore, the object (technical problem) to be solved by the present invention is, as described above, to prevent deformation traces from being generated at the joint portion due to the engagement between the bracket and the building board, and to be simple and quick. The purpose is to allow the construction of the enclosure.

そこで発明者は、前記課題を解決すべく、鋭意，研究を重ねた結果、請求項１の発明を、略方形状の頂部と、該頂部の外周囲に形成され且つ断面を外方に凸とした円弧状の幕状縁と、前記頂部の幅方向両側における前記幕状縁から外方下向きに傾斜形成された嵌合板部と、前記頂部より略垂下状に形成された柱状部と、該柱状部の下端に形成された台座部とからなり、前記柱状部の上方且つ幅方向両端箇所で前記幕状縁の直下の位置には内部側に窪むくびれ部が形成され、前記嵌合板部は、前記頂部の前後方向に沿って略長方形状に形成されると共に、前記嵌合板部の前後方向長さは前記頂部の前後方向の範囲内に収まり、且つ前記嵌合板部の前後方向長は、前記頂部の幅方向両側における前記幕状縁の前後方向の長さより小さく形成されてなる受金具としたことにより、上記課題を解決した。 Accordingly, as a result of intensive studies and researches, the inventor has found that the invention of claim 1 is formed in a substantially rectangular top portion, an outer periphery of the top portion, and a cross-section projecting outward. An arcuate curtain-like edge, a fitting plate part inclined outwardly from the curtain-like edge on both sides in the width direction of the top part, a columnar part formed substantially downwardly from the top part, and the columnar part A pedestal part formed at the lower end of the part, and a constricted part that is recessed on the inner side is formed at a position directly above the columnar part and directly below the curtain-like edge at both ends in the width direction. The front and rear direction length of the fitting plate portion is within a range of the front and rear direction of the top portion, and the front and rear direction length of the fitting plate portion is formed in a substantially rectangular shape along the front and rear direction of the top portion. It is formed smaller than the length in the front-rear direction of the curtain edge on both sides in the width direction of the top. That by which the pivot bracket, the above-mentioned problems are eliminated.

請求項２の発明を、請求項１において、前記嵌合板部の幅方向外端箇所には内方側に向かって略円弧状の第１屈曲端縁が形成されてなる受金具としたことにより、上記課題を解決した。請求項３の発明を、請求項１又は２において、前記嵌合板部の前後方向両端には内方側に向かって略円弧状の第２屈曲端縁が形成されてなる受金具としたことにより、上記課題を解決した。 According to a second aspect of the present invention, in the first aspect of the present invention, a fitting is formed by forming a substantially arc-shaped first bent end edge inward in the width direction outer end portion of the fitting plate portion. The above problem has been solved. According to a third aspect of the present invention, in the first or second aspect of the present invention, the fitting plate portion is formed as a receiving bracket in which a substantially arc-shaped second bent end edge is formed at both ends in the front-rear direction. The above problem has been solved.

請求項１の発明は、前記嵌合板部は、前記頂部の前後方向に沿って略長方形状に形成されると共に、前記嵌合板部の前後方向長さは前記頂部の前後方向の範囲内に収まる受金具としたものである。前記嵌合板部は、前記頂部の前後方向の範囲内に収められた構造であり、嵌合建築用板を本発明の受金具に嵌合固定するときには、受金具の頂部が嵌合建築用板の被嵌合山形部に入り込むことによって、幅方向両側に押し広げられ、頂部の前後方向の範囲内に収まっている嵌合板部が嵌合建築用板の被嵌合部に嵌合することができるものである。 In the invention of claim 1, the fitting plate portion is formed in a substantially rectangular shape along the front-rear direction of the top portion, and the length of the fitting plate portion in the front-rear direction falls within the range of the front-rear direction of the top portion. It is a receiving bracket. The fitting plate portion has a structure housed in a range in the front-rear direction of the top portion, and when the fitting construction plate is fitted and fixed to the fitting of the present invention, the top portion of the fitting is a fitting construction plate. The fitting plate portion that is pushed and spread on both sides in the width direction and is within the range in the front-rear direction of the top portion can be fitted to the fitting portion of the fitting construction plate. It can be done.

このため、前記受金具の嵌合板部が嵌合建築用板の被嵌合部の位置に到達して嵌合が完了するまでの過程において、前記受金具の頂部によって、嵌合建築用板の裏面側に嵌合板部が強く当接しないように保護される。そして、前記嵌合板部が嵌合建築用板に嵌合する過程で嵌合板部によって、嵌合建築用板の内方側に傷痕が形成され難いものにでき、傷痕が残り難いものにできる。 For this reason, in the process until the fitting plate part of the fitting reaches the position of the fitted part of the fitting building plate and the fitting is completed, the top of the fitting makes the fitting building plate It protects so that a fitting board part may not contact | abut strongly on the back side. And in the process in which the said fitting board part fits the board for fitting construction, it can be made into a thing in which a scar is hard to be formed in the inner side of a board for fitting construction by a fitting board part, and a scar is hard to remain.

さらに、前記受金具の嵌合板部は、前記頂部の前後方向に沿って略長方形状に形成されているので、この受金具を前記嵌合板部と嵌合する被嵌合部が形成された山形部を有する嵌合タイプの建築用板の山形部に嵌合したときに、前記嵌合板部は装着の前後方向が建築用板の山形部の長手方向に沿って略連続する線状に接触することとなる。これによって前記嵌合板部と山形部に形成された被嵌合部との接触が連続する略面状の接触となり、受金具に嵌合建築用板を極めて強固に嵌合固定することができる。さらに、前記柱状部の上方且つ幅方向両端箇所には内部側に窪むくびれ部が形成されたことにより、嵌合建築用板の被嵌合部の内部側に突出する部位が入り込み易い構造となり、嵌合建築用板を安定した状態で嵌合することができる。 Further, since the fitting plate portion of the metal fitting is formed in a substantially rectangular shape along the front-rear direction of the top portion, a mountain shape in which a fitting portion for fitting the metal fitting with the fitting plate portion is formed. When the fitting plate portion is fitted to a mountain-shaped portion of a fitting-type building board having a portion, the fitting plate portion comes into contact with a linear shape in which the front-rear direction of mounting is substantially continuous along the longitudinal direction of the mountain-shaped portion of the building plate. It will be. As a result, the contact between the fitting plate portion and the portion to be fitted formed in the chevron portion becomes a substantially planar contact, and the fitting construction plate can be fitted and fixed extremely firmly to the metal fitting. Further, the constricted portion formed on the inner side is formed at both ends in the width direction above the columnar portion, so that a portion protruding to the inner side of the mated portion of the mating building plate can easily enter. The fitting building board can be fitted in a stable state.

さらに、請求項１の発明では、前記頂部の外周囲には幕状縁が形成され、前記頂部の幅方向における幕状縁から前記嵌合板部が形成されると共に前記幕状縁は、断面が外方に凸とした円弧状としたことにより、嵌合する時において嵌合建築用板に対して当接部分が曲面接触となり、嵌合建築用板に傷を付け難いものにできる。 Further, in the invention of claim 1, a curtain-like edge is formed on the outer periphery of the top, the fitting plate portion is formed from the curtain-like edge in the width direction of the top, and the curtain-like edge has a cross section. By forming the arc shape so as to protrude outward, the contact portion becomes a curved contact with the mating building board when mating, and the mating building board can be hardly damaged.

請求項２の発明では、前記嵌合板部の幅方向外端箇所には内方側に向かって略円弧状の屈曲端縁が形成されてなる受金具としたことにより、嵌合する時と嵌合終了時において嵌合建築用板に対して前記嵌合板部の幅方向における外端との当接部分が曲面接触となり、嵌合建築用板に傷を付け難いものにできる。また、請求項３の発明によって、前記嵌合板部の前後方向両端には内方側に向かって略円弧状の屈曲端縁が形成されなる受金具としたことにより、嵌合する時と嵌合終了時において嵌合建築用板に対して前記嵌合板部の前後方向両端との当接部分が曲面接触となり、嵌合建築用板に傷を付け難いものにできる。
According to the second aspect of the present invention, when the fitting plate part is formed with a substantially arc-shaped bent end edge at the outer end portion in the width direction of the fitting plate portion, At the end of the mating, the contact portion with the outer end in the width direction of the fitting plate portion becomes a curved surface contact with the fitting building plate, and the fitting building plate can be hardly damaged. Further, according to the invention of claim 3, when the fitting plate part is formed with a receiving bracket in which a substantially arc-shaped bent end edge is formed at both ends in the front-rear direction of the fitting plate portion, At the end, the contact portion of the fitting plate portion with the both ends in the front-rear direction becomes curved contact with the fitting building plate, and the fitting building plate can be hardly damaged.

以下、本発明の実施形態を図面に基づいて説明する。本発明における受金具の第１実施形態は、頂部１,嵌合板部２，柱状部３及び台座部４とからなり、金属製であり、前記頂部１は、平面的に見て、略方形状に形成されており、具体的には、長方形又は正方形に形成されている。前記頂部１の周囲は、下方に向かって、幕状縁１１が形成されており、該幕状縁１１は、頂部１の平坦状部から略垂直状に垂れ下がるようにして形成されると共に、頂部１の平坦面部となす断面形状が略円弧形状に曲面を有しながら形成されたものである。前記幕状縁１１は、前記頂部１の強度を補強して強固なものとし、また後述する嵌合建築用板Ａを受金具に嵌合固定するときの案内の役目をなすものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The first embodiment of the metal fitting according to the present invention includes a top portion 1, a fitting plate portion 2, a columnar portion 3, and a pedestal portion 4, and is made of metal, and the top portion 1 is substantially rectangular in a plan view. Specifically, it is formed in a rectangle or a square. A curtain-like edge 11 is formed around the top 1 downward, and the curtain-like edge 11 is formed so as to hang from the flat part of the top 1 in a substantially vertical shape. The cross-sectional shape formed by the flat surface portion 1 is formed in a substantially arc shape with a curved surface. The curtain edge 11 reinforces the strength of the top portion 1 to be strong, and also serves as a guide when fitting and fixing a fitting building plate A, which will be described later, to a bracket.

受金具は、説明において便宜的に前後方向及び幅方向が決められている。その前後方向とは、図２に示すように、嵌合建築用板Ａを前記受金具に嵌合固定した状態で、嵌合建築用板Ａの被嵌合山形部６（又は嵌合山形部７）の長手方向に一致する方向のことである。また受金具の幅方向とは、図２に示すように、前記嵌合建築用板Ａを、前記受金具に嵌合固定した状態で嵌合建築用板Ａの被嵌合山形部６（又は嵌合山形部７）の長手方向に直交する方向のことである。さらに、受金具の前後方向及び幅方向は、図１に矢印にて開示されている。 For the sake of convenience, the front and rear direction and the width direction of the metal fitting are determined in the description. As shown in FIG. 2, the front-rear direction means that the fitting building plate A (or fitting mountain portion) of the fitting building plate A is in a state where the fitting building plate A is fitted and fixed to the bracket. It is the direction that matches the longitudinal direction of 7). In addition, as shown in FIG. 2, the width direction of the receiving bracket means that the fitting building plate A of the fitting building plate A (or the fitting building plate A is fitted in the state where the fitting building plate A is fitted and fixed to the receiving bracket). It is a direction orthogonal to the longitudinal direction of the fitting chevron 7). Furthermore, the front-rear direction and the width direction of the metal fitting are disclosed by arrows in FIG.

嵌合板部２は、図１（Ａ），（Ｂ）に示すように、前記頂部１の幅方向両側より外方下向きに傾斜形成されたものであり、略長方形の板片形状に形成されている。前記嵌合板部２は、前記頂部１の前後方向に沿って略長方形状に形成されている〔図１（Ａ），（Ｃ）参照〕。また、前記嵌合板部２は、その前後方向長さが前記頂部１の前後方向の長さよりも短く形成されている〔図１（Ａ），（Ｃ）参照〕。すなわち、嵌合板部２は、前記頂部１の前後方向の範囲内に収まるように形成されたものであり、前記頂部１の前後方向の長さをＬａとし、前記嵌合板部２の前後方向の長さをＬｂとすると、Ｌａ＞Ｌｂとなる。該嵌合板部２は、前記頂部１の幅方向にのみ突出する形状となっている。 As shown in FIGS. 1 (A) and 1 (B), the fitting plate portion 2 is formed to be inclined outward and downward from both sides in the width direction of the top portion 1 and is formed in a substantially rectangular plate-like shape. Yes. The fitting plate portion 2 is formed in a substantially rectangular shape along the front-rear direction of the top portion 1 (see FIGS. 1A and 1C). In addition, the fitting plate portion 2 is formed so that the length in the front-rear direction is shorter than the length in the front-rear direction of the top portion 1 (see FIGS. 1A and 1C). That is, the fitting plate portion 2 is formed so as to be within the range of the top portion 1 in the front-rear direction, the length of the top portion 1 in the front-rear direction is La, and the fitting plate portion 2 is arranged in the front-rear direction. When the length is Lb, La> Lb. The fitting plate portion 2 has a shape protruding only in the width direction of the top portion 1.

嵌合板部２は、前記頂部１と一体形成されたものである。さらに具体的には、前記頂部１の幅方向における幕状縁１１から一体成形されたものである。前記嵌合板部２は、前記該幕状縁１１の部分によって、前記頂部１と嵌合板部２との連続する箇所の断面形状は、円弧形状となっている〔図１（Ａ），（Ｂ）参照〕。これによって、建築用板を受金具の頂部１から嵌合するときには、前記幕状縁１１によって滑らかに前記嵌合板部２に案内されることができる。 The fitting plate portion 2 is integrally formed with the top portion 1. More specifically, it is integrally formed from the curtain-like edge 11 in the width direction of the top portion 1. In the fitting plate portion 2, the cross-sectional shape of the continuous portion between the top portion 1 and the fitting plate portion 2 is an arc shape by the portion of the curtain-shaped edge 11 [FIGS. )reference〕. As a result, when the building board is fitted from the top 1 of the bracket, it can be smoothly guided to the fitting board 2 by the curtain edge 11.

受金具の第２実施形態として、前記嵌合板部２は、さらに幅方向外端箇所に頂部１の下面側で且つ内方側に向かって略円弧状の第１屈曲端縁２１が形成されるものが存在する。該実施形態では、図４（Ａ）,（Ｂ）に示すように、前記頂部１の幅方向と同一方向における嵌合板部２の外端に第１屈曲端縁２１が形成されるものであって、略カーリング（巻込み加工）によって形成されてもかまわない。前記嵌合板部２に第１屈曲端縁２１が形成されることによって、嵌合建築用板Ａを受金具に嵌合固定する過程で、前記嵌合板部２は建築用板に対して傷痕をほとんど残すことなく嵌合固定させることができる〔図４（Ｂ）参照〕。 As a second embodiment of the bracket, the fitting plate portion 2 is further formed with a substantially arc-shaped first bent end edge 21 on the lower surface side of the top portion 1 and toward the inner side at the outer end portion in the width direction. Things exist. In this embodiment, as shown in FIGS. 4A and 4B, a first bent edge 21 is formed at the outer end of the fitting plate portion 2 in the same direction as the width direction of the top portion 1.

And the fitting chevron part 7 can be overlap | superposed and fitted to the to-be-fitted chevron part 6 of adjacent board | plates A and A for fitting construction [FIG. 3 (A), FIG. See C)]. Specifically, as shown in FIG. 2, a fitted portion 62 is formed above the fitted chevron 6. A fitting portion 72 is formed above the fitting chevron 7.

前記被嵌合山形部６は、図５（Ｂ）,（Ｃ）に示すように、前記主板５の幅方向一方側の端部から傾斜状部６１が形成され、該傾斜状部６１の上端に被嵌合部６２が形成されている。該被嵌合部６２は幅方向両側より円弧状に膨出する被嵌合屈曲片６２ａ，６２ａが形成されている。前記嵌合山形部７は、図５（Ｂ）,（Ｃ）に示すように、前記主板５の幅方向他方側の端部から傾斜状部７１が形成され、該傾斜状部７１の上端に嵌合部７２が形成されている。該嵌合部７２は幅方向両側より円弧状に膨出する嵌合屈曲片７２ａ，７２ａが形成されている。 As shown in FIGS. 5B and 5C, the fitted chevron 6 has an inclined portion 61 formed from an end portion on one side in the width direction of the main plate 5, and an upper end of the inclined portion 61. A mating portion 62 is formed on the inner surface. The to-be-fitted portion 62 is formed with to-be-fitted bent pieces 62a and 62a that bulge out in an arc shape from both sides in the width direction. As shown in FIGS. 5 (B) and 5 (C), the fitting chevron 7 is formed with an inclined portion 71 from an end on the other side in the width direction of the main plate 5, and an upper end of the inclined portion 71 is formed. A fitting portion 72 is formed. The fitting portion 72 is formed with fitting bent pieces 72a, 72a that bulge out in an arc shape from both sides in the width direction.

前記被嵌合屈曲片６２ａ，６２ａと、前記嵌合屈曲片７２ａ，７２ａとは、略同等（略同一）形状に形成されたものであり、且つ前記嵌合山形部７の形状は、前記被嵌合山形部６の形状よりも略板厚１枚分だけ大きくなるように形成されている。これによって、前記嵌合建築用板Ａの被嵌合山形部６に、隣接する嵌合建築用板Ａの嵌合山形部７が上から重ねられて嵌合された状態で略密着状態となる〔図３（Ａ）参照〕。前記主板５の幅方向の中央箇所には、中央山形部５１が形成されることもある〔図５（Ａ），（Ｂ）参照〕。該中央山形部５１は、被嵌合山形部６と略同等形状に形成されている。 The fitted bent pieces 62a, 62a and the fitted bent pieces 72a, 72a are formed in substantially the same (substantially the same) shape, and the shape of the fitted chevron portion 7 is the shape of the covered bent piece 7a. It is formed so as to be larger by approximately one plate thickness than the shape of the fitting chevron 6. As a result, the fitting chevron portion 7 of the mating building board A adjacent to the mating chevron portion 6 of the mating building board A is overlapped from above and fitted into a substantially close contact state. [See FIG. 3A]. A central chevron 51 may be formed at the center of the main plate 5 in the width direction (see FIGS. 5A and 5B). The central chevron 51 is formed in substantially the same shape as the fitted chevron 6.

次に、本発明における受金具によって、嵌合建築用板Ａにて屋根，壁等の外囲体を施工する工程を説明する。まず、受金具は、母屋，胴縁等の構造材８に所定間隔をおいて固定される。該構造材８の長手方向は前記嵌合建築用板Ａの長手方向に直交（略直交も含む）する。隣接する受金具に嵌合建築用板Ａが配置され、被嵌合山形部６が受金具に嵌合固定される。 Next, the process of constructing an enclosure such as a roof or a wall with the fitting construction plate A by the metal fitting according to the present invention will be described. First, the metal fitting is fixed to the structural material 8 such as a purlin or a trunk edge at a predetermined interval. The longitudinal direction of the structural member 8 is orthogonal (including substantially orthogonal) to the longitudinal direction of the fitting building board A. The fitting building plate A is arranged on the adjacent receiving metal fitting, and the fitting chevron 6 is fitted and fixed to the receiving metal fitting.

次に、新たな嵌合建築用板Ａの嵌合山形部７を、すでに構造材８に固定された嵌合建築用板Ａの被嵌合部６２上に配置し〔図５（Ｃ）参照〕、該被嵌合山形部６上に押し付けて被嵌合部６２と嵌合部７２とを密着状態で嵌合させる〔図３（Ａ）参照〕。このとき嵌合状態は両被嵌合屈曲片６２ａ，６２ａと両嵌合屈曲片７２ａ，７２ａとが密着状態で嵌合する。これが、幅方向に順次連結されて、嵌合外囲体が施工されてゆく。 Next, the fitting chevron 7 of the new fitting building board A is placed on the fitted part 62 of the fitting building board A already fixed to the structural material 8 [see FIG. 5 (C). Then, the portion to be fitted 62 and the fitting portion 72 are fitted in close contact with each other by being pressed onto the fitting chevron 6 (see FIG. 3A). At this time, the fitted state is such that the fitted bent pieces 62a, 62a and the fitted bent pieces 72a, 72a are fitted in close contact. This is sequentially connected in the width direction, and the fitting enclosure is constructed.

本発明の受金具では、前記嵌合板部２は、前記頂部１の前後方向に沿って略長方形状に形成されると共に、前記嵌合板部２の前後方向長Ｌｂは、前記頂部１の前後方向の長さＬａより小さく、前記嵌合板部２が頂部１の前後方向の範囲内に収まる構造としたものである。嵌合建築用板Ａを本発明の受金具に嵌合固定するときには、受金具の頂部１が嵌合建築用板Ａの被嵌合山形部６の裏面側に入り込み、これによって幅方向両側に押し広げられ、頂部１の前後方向の範囲内に収まっている嵌合板部２が嵌合建築用板Ａの被嵌合部６２の被嵌合屈曲片６２ａに嵌合することができるものである。 In the bracket of the present invention, the fitting plate portion 2 is formed in a substantially rectangular shape along the front-rear direction of the top portion 1, and the front-rear direction length Lb of the fitting plate portion 2 is the front-rear direction of the top portion 1. The fitting plate portion 2 is smaller than the length La and fits within the range of the top portion 1 in the front-rear direction. When the fitting building plate A is fitted and fixed to the metal fitting of the present invention, the top 1 of the metal fitting enters the back side of the fitting chevron 6 of the fitting building plate A, and thereby on both sides in the width direction. The fitting plate portion 2 that is pushed and spread within the range in the front-rear direction of the top portion 1 can be fitted into the fitting bent piece 62a of the fitting portion 62 of the fitting building plate A. .

このため、受金具の嵌合板部２が嵌合建築用板Ａの被嵌合部６２の位置に到達して嵌合が完了するまでの過程において、前記受金具の頂部１によって、嵌合建築用板Ａの裏面側に嵌合板部２が強く当接しないように保護される〔図６（Ａ）,（Ｂ）参照〕、前記嵌合板部２が嵌合建築用板Ａに嵌合する過程で嵌合板部２によって、嵌合建築用板Ａの内方側に傷痕が形成され難いものにでき、傷痕が残り難いものにできる〔図６（Ｃ）,（Ｄ）参照〕。 For this reason, in the process until the fitting board part 2 of a metal fitting reaches the position of the to-be-fitted part 62 of the board A for fitting construction, and fitting is completed, it is fitting construction by the top part 1 of the said metal fitting. The fitting plate portion 2 is protected from coming into strong contact with the back side of the working plate A (see FIGS. 6A and 6B), and the fitting plate portion 2 is fitted to the fitting construction plate A. In the process, the fitting plate portion 2 can make it difficult for a scar to be formed on the inner side of the fitting building plate A and make it difficult to leave a scar (see FIGS. 6C and 6D).

さらに、前記受金具の嵌合板部２は、前記頂部１の前後方向に沿って略長方形状に形成されているので、この受金具を前記嵌合板部２と嵌合する被嵌合部６２が形成された被嵌合山形部６に嵌合したときに、前記嵌合板部は装着の前後方向が建築用板の山形部の長手方向に沿って略連続する線状に接触することとなる〔図３（Ｂ）,（Ｃ）参照〕。これによって、従来の爪（ｃ）（係止片）の嵌合終了時点での点接触より、前記嵌合板部２と被嵌合部６２との接触領域が連続する略面状の接触となり、接触面が大きくなることで、受金具に嵌合建築用板Ａを更に極めて強固に嵌合固定することができる。 Furthermore, since the fitting plate portion 2 of the receiving bracket is formed in a substantially rectangular shape along the front-rear direction of the top portion 1, a fitted portion 62 for fitting the receiving bracket to the fitting plate portion 2 is provided. When fitted to the formed to-be-fitted chevron 6, the fitting plate part comes into contact with a linear shape in which the front-rear direction of mounting is substantially continuous along the longitudinal direction of the chevron part of the building board [ See FIGS. 3B and 3C]. Thereby, from the point contact at the end of fitting of the conventional claw (c) (locking piece), the contact area between the fitting plate part 2 and the fitted part 62 becomes a substantially planar contact, By increasing the contact surface, the fitting building plate A can be more firmly fitted and fixed to the bracket.
