Description

本発明は、建物のベランダ等の室外側端部に設置される手摺りに関するもので、特に、堰壁上に一定間隔をおいて立設される支柱と、これら支柱の上端部をつなぐ上枠と、支柱の下端部をつなぐ下枠とによって矩形状の手摺り枠体を形成し、この手摺り枠体の左右に対向する支柱と上枠と下枠とからなる各ガラス取付枠にガラス板を嵌装するようにした手摺りのガラス板取付構造に関する。 TECHNICAL FIELD The present invention relates to a handrail installed on an outdoor end of a building veranda, and in particular, a column that stands on a dam wall at a predetermined interval and an upper frame that connects the upper ends of these columns. And a lower frame connecting the lower ends of the columns, a rectangular handrail frame is formed, and a glass plate is attached to each glass mounting frame composed of columns, upper frames, and lower frames opposed to the left and right of the handrail frame. The present invention relates to a glass plate mounting structure for a handrail that is adapted to be fitted.

従来におけるこの種手摺りのガラス板取付構造として、特許公報等の具体的な公知文献を挙げることはできないが、現在使用されている高さ１．２ｍの手摺りにおいては、矩形状のガラス取付枠体を形成する支柱の見附幅が５ｃｍ程度以上と可なり大きいことから、室内外から見た支柱の見栄えが良くない。 As a conventional glass plate mounting structure of this kind of handrail, it is not possible to list specific publicly known documents such as patent gazettes, but in the handrail with a height of 1.2 m currently used, a rectangular glass mounting Since the support width of the pillars forming the frame is as large as about 5 cm or more, the appearance of the pillars viewed from the inside and outside of the room is not good.

従来のガラス取付枠の支柱の見附幅を５ｃｍ程度以上と幅広くせざるを得ない理由は、各支柱が、室内外方向に間隔をおいた内外一対の枠部と、両枠部をつなぐと共に、両枠部間の空間を左右に仕切って左右両側にガラス嵌合溝を形成する仕切壁とにより構成されていて、ガラス取付枠にガラス板を嵌め込むのに、ガラス板の一側端部を左右支柱の何れか一方のガラス嵌合溝に深く嵌め込んだ後、ガラス板の他側端部を他方のガラス嵌合溝に嵌め込んで左右方向にスライドさせる、言わば左右検鈍式によって、ガラス板をガラス取付枠に嵌め込むことから、仕切壁の両側に形成されるガラス嵌合溝の深さを十分に深くする必要があり、それがために支柱の見附幅がどうしても幅広くなり、外観上の体裁、見栄えが悪い。 The reason why the supporting width of the supporting column of the conventional glass mounting frame has to be as wide as about 5 cm or more is that each supporting column connects a pair of inner and outer frame portions spaced in the indoor and outdoor directions, and both frame portions, It is composed of a partition wall that partitions the space between both frame parts to the left and right and forms glass fitting grooves on both the left and right sides, and one side edge of the glass plate is used to fit the glass plate into the glass mounting frame. After deeply fitting into one of the glass fitting grooves on either of the left and right columns, the other end of the glass plate is fitted into the other glass fitting groove and slid in the left-right direction. Since the plate is fitted into the glass mounting frame, the depth of the glass fitting grooves formed on both sides of the partition wall must be made sufficiently deep. Looks and looks bad.

本発明は、上記の事情に鑑み、支柱の目地枠部分の目地幅をできるだけ小さくすると共に目地枠部分がガラス面から出っ張らないようにして、外観上の体裁、見栄えを良くし、更にガラス板の取付作業を簡単に行えるようにしたガラス板取付構造を提供することを目的とする。 In view of the above circumstances, the present invention reduces the joint width of the joint frame portion of the support column as much as possible and prevents the joint frame portion from protruding from the glass surface to improve the appearance and appearance of the glass plate. It is an object of the present invention to provide a glass plate mounting structure that allows easy mounting work.

A screw body 26b is provided at the inner side edge of the lower plate portion 26b at the inner side surface of the opposed end portions 4a and 4a. A locking edge portion 26d that is locked to the upper end portion of the outdoor side surface of the opposed end portions 4a, 4a is provided at the upper end portion.

上記下枠４を支柱２に取り付けるにあたっては、下枠４の端部４ａの室内側部分を平面視略Ｌ字状に切欠して、その切欠部４ｏを、図４の(a) 及び図５に示すように、支柱本体８の室外側面及びこれに隣接する横側面部にわたって係合した状態で、下枠４内の室内側で上下に対向突出する上下フランジ片２７，２８から夫々支柱本体８の室外側面に対してビス２９をねじ込むことにより、下枠４の端部４ａを支柱本体８に固定する。 When attaching the lower frame 4 to the column 2, the indoor side portion of the end portion 4a of the lower frame 4 is cut out in a substantially L shape in plan view, and the cutout portion 4o is formed as shown in FIGS. As shown in FIG. 2, the column main body 8 is respectively protruded from the upper and lower flange pieces 27 and 28 that protrude vertically opposite to each other on the indoor side in the lower frame 4 while being engaged over the outdoor side surface of the column main body 8 and the lateral side surface adjacent thereto. The end portion 4a of the lower frame 4 is fixed to the column main body 8 by screwing the screw 29 into the outdoor side surface.

この場合、下枠４内の室内側上部フランジ片２７から支柱本体８の室外側面にビス２９をねじ込むにあたり、下枠端部４ａの室外側側壁３１上部から室外側受けゴム取付溝３３及び室内側バックアップシール材取付溝３４にわたってドリル、ビス、ドライバー挿通用の孔（図示省略）を開ける必要があり、図５には下枠端部４ａの室外側側壁３１上部に設けた孔を３５で示す。また、下枠端部４ａの室外側側壁３１下部に同様にドリル、ビス、ドライバー挿通用の孔３６を開ける。しかして、この下枠端部４ａの室外側側壁３１上部に設けた孔３５から、先ずドリルを挿入して、下枠４室内側の上部フランジ片２７と、下枠端部４ａの室内側側壁３２上部とにビス挿通用孔を開け、次いで室外側側壁３１の下部の孔３６からドリルを挿入して、下枠４室内側の下部フランジ片２８と、下枠端部４ａの室内側側壁３２下部とにビス挿通用孔を開ける。この後、前記孔３５から上部フランジ片２７及び室内側側壁３２のビス挿通用孔にビス２９を挿入して、ドライバー（図示せず）で支柱本体８の室外側面にビス２９をねじ込み、また前記孔３６から下部フランジ片２８及び室内側側壁３２のビス挿通用孔にビス２９を挿入して、ドライバーで支柱本体８の室外側面にビス２９をねじ込めばよい。 In this case, when the screw 29 is screwed from the indoor upper flange piece 27 in the lower frame 4 to the outdoor side surface of the column main body 8, the outdoor receiving rubber mounting groove 33 and the indoor side from the upper part of the outdoor side wall 31 of the lower frame end 4a. It is necessary to open a hole (not shown) for inserting a drill, a screw, and a driver over the backup seal material mounting groove 34. FIG. 5 shows a hole 35 provided in the upper part of the outdoor side wall 31 of the lower frame end 4a. Similarly, a hole 36 for inserting a drill, a screw, and a screwdriver is formed in the lower part of the lower frame end 4a at the lower part of the outdoor side wall 31. Thus, first, a drill is inserted from the hole 35 provided in the upper part of the outdoor side wall 31 of the lower frame end 4a, and the upper flange piece 27 on the indoor side of the lower frame 4 and the indoor side wall of the lower frame end 4a. 32, a screw insertion hole is drilled in the upper part, and then a drill is inserted through a hole 36 in the lower part of the outdoor side wall 31 so that the lower flange piece 28 on the inner side of the lower frame 4 and the indoor side wall 32 of the lower frame end 4a. Open a screw insertion hole at the bottom. Thereafter, a screw 29 is inserted into the upper flange piece 27 and the screw insertion hole of the indoor side wall 32 from the hole 35, and the screw 29 is screwed into the outdoor side surface of the column body 8 with a screwdriver (not shown). The screw 29 may be inserted into the lower flange piece 28 and the screw insertion hole of the indoor side wall 32 from the hole 36 and screwed into the outdoor side surface of the column body 8 with a screwdriver.

化粧カバー２６を図５の仮想線で示すように両下枠４，４の対向端部４ａ，４ａにわたって取り付けるには、カバー本体２６ａｂを下枠４の室外側面及び底面に嵌合させ、ビス止片２６ｃを下枠４の室内側下端コーナー部に係合させると共に、係止縁部２６ｄを下枠４の室外側面上端部に係止させ、そしてビス止片２６ｃを、図４の(a) に示すようにビス３７で下枠４の室内側側壁３２に対して固定する。こうして図５の仮想線で示すように両下枠４，４の対向端部４ａ，４ａにわたって化粧カバー２６を取り付けることにより、両下枠４，４の対向端部４ａ，４ａの間隙２５が覆い隠されると共に、下枠４の室外側側壁３１に設けられた孔３５，３６が覆い隠されるから、両下枠４，４の対向端部４ａ，４ａにおける室外側での外観上の体裁、見栄えを良くすることができる。 In order to attach the decorative cover 26 over the opposite ends 4a and 4a of the lower frames 4 and 4 as shown by phantom lines in FIG. 5, the cover main body 26ab is fitted to the outdoor side surface and the bottom surface of the lower frame 4, The piece 26c is engaged with the lower end corner portion on the indoor side of the lower frame 4, the engaging edge portion 26d is engaged with the upper end portion on the outdoor side surface of the lower frame 4, and the screw stopping piece 26c is replaced with the screw stop piece 26c shown in FIG. As shown in FIG. 5, the screw 37 is fixed to the indoor side wall 32 of the lower frame 4. Thus, as shown by the phantom lines in FIG. 5, the decorative cover 26 is attached over the opposite ends 4a, 4a of the lower frames 4, 4, thereby covering the gap 25 between the opposite ends 4a, 4a of the lower frames 4, 4. Since the holes 35 and 36 provided in the outdoor side wall 31 of the lower frame 4 are concealed and concealed, the appearance and appearance on the outdoor side at the opposite end portions 4a and 4a of the lower frames 4 and 4 are concealed. Can be improved.

尚、図１に示す手摺りにおける各ガラス取付枠５の寸法の一例を示せば、左右に対向する支柱２，２間のピッチＰは１２００ｍｍ、目地枠９の化粧縁１３に先付けビート１４を取り付けた状態での目地幅ｖ（図４の(a) 参照）は約１５ｍｍ、化粧縁１３の幅ｗ（図４の(a) 参照）は１０ｍｍ、上枠３の厚み幅ｎは３０ｍｍ、下枠４の厚み幅ｍは３０ｍｍ、手摺り高さＨは１２００ｍｍである。 In addition, if an example of the dimension of each glass mounting frame 5 in the handrail shown in FIG. 1 is shown, the pitch P between the columns 2 and 2 facing left and right is 1200 mm, and the leading beat 14 is attached to the decorative edge 13 of the joint frame 9. The joint width v (see FIG. 4 (a)) is about 15 mm, the width w of the decorative edge 13 (see FIG. 4 (a)) is 10 mm, the thickness width n of the upper frame 3 is 30 mm, and the lower frame 4 has a thickness width m of 30 mm and a handrail height H of 1200 mm.

次に、上述した図１に示す手摺りのガラス取付枠５にガラス板６を嵌装する手順を主に図７の(a) 〜(d) を中心に他の図を参照して説明する。このガラス板６の嵌装にあたり、図７の(a) に示すように、上枠３は支柱本体８の上端に未だ取り付けていない状態とし、また各ガラス取付枠５の支柱２には目地枠９の化粧縁１３の両端部に先付けビート１４を取り付けて、図５に示すような状態にしておく。 Next, a procedure for fitting the glass plate 6 on the glass mounting frame 5 of the handrail shown in FIG. 1 will be described with reference to other drawings mainly with reference to (a) to (d) of FIG. . When the glass plate 6 is fitted, as shown in FIG. 7A, the upper frame 3 is not yet attached to the upper end of the column main body 8 and the joint frame is attached to the column 2 of each glass mounting frame 5. The leading beats 14 are attached to both ends of the decorative edge 13 of No. 9, and the state shown in FIG.

それから、左右に対向する両突条壁１２，１２のガラス嵌合部１１，１１間にガラス板６を図７の(a) に示すように上方より挿入して、ガラス板端部６ａの凹段部６ｏに先付けビート１４を突入嵌合させた状態とし、それによって目地枠９の化粧縁１３は図４の(a) に示すように、その外面がガラス板６の室外面から出っ張らず、それとほとんど面一状態となる。この時、ガラス板６の下端部は、図７の(b) に示すように下枠４内のガラス嵌合部２２に納まって、セッティングブロック（スペーサ）３０上に支持されると共に、室外側の受けゴム２３と室内側のバックアップシール材２４とで挟持されてシールされる。 Then, a glass plate 6 is inserted from above between the glass fitting portions 11 and 11 of both protruding wall 12 and 12 facing left and right, as shown in FIG. As shown in FIG. 4 (a), the outer edge of the joint edge 9 of the joint frame 9 does not protrude from the outdoor surface of the glass plate 6, It becomes almost flush with it. At this time, the lower end portion of the glass plate 6 is housed in the glass fitting portion 22 in the lower frame 4 and supported on the setting block (spacer) 30 as shown in FIG. Are sandwiched and sealed between the receiving rubber 23 and the indoor backup seal material 24.

上記のようにしてガラス板６の左右両端部を左右に対向する両突条壁１２，１２のガラス嵌合部１１，１１間に嵌め入れると共に、ガラス板６の下端部を下枠４内のガラス嵌合部２２に嵌め込んだ後、目地枠９の基台部１０とガラス板６との間に押えビート１５を挿入して、この押えビート１５によりガラス板６の左右端部室内面を押え付け、それによりガラス板６のガラス板６の左右端部室外面を先付けビート１４に密接させる。即ち、押えビート１５を基台部１０とガラス板６との間に挿入することにより、ガラス板６の左右端部室外面が先付けビート１４に押し付けられて、ガラス板６の左右端部が室内側の押えビート１５と室外側の先付けビート１４とで確実に保持固定されると共に、両ビート１４，１５がガラス板６と金属製目地枠９との緩衝材として機能するため、衝撃や振動等によるガラス板６の破損を防止することができる。 As described above, the left and right end portions of the glass plate 6 are fitted between the glass fitting portions 11 and 11 of the both protruding rib walls 12 and 12 facing left and right, and the lower end portion of the glass plate 6 is placed in the lower frame 4. After fitting into the glass fitting portion 22, a presser beat 15 is inserted between the base portion 10 of the joint frame 9 and the glass plate 6, and the left and right end interior surfaces of the glass plate 6 are moved by the presser beat 15. By pressing, the outer surfaces of the left and right end chambers of the glass plate 6 are brought into close contact with the leading beat 14. That is, by inserting the presser beat 15 between the base 10 and the glass plate 6, the left and right ends of the glass plate 6 are pressed against the leading beat 14, and the left and right ends of the glass plate 6 are placed indoors. The presser beat 15 and the outdoor beading beat 14 are securely held and fixed, and both the beats 14 and 15 function as a buffer material between the glass plate 6 and the metal joint frame 9, so Breakage of the glass plate 6 can be prevented.

次いで、図７の(c) に示すように、上枠３の取付基枠１８を支柱本体８の上端面にビス１７で固定し、そしてこの取付基枠１８に笠木部材１９を被嵌して、図７の(d) に示すような状態とする。取付基枠１８に形成されるガラス嵌合部１６の室内側にはペースト状のシール材３８を詰め込み、また下枠４のガラス嵌合部２２の室内側にもペースト状のシール材３８を詰め込む。これによって、ガラス板６の嵌め込みを終了する。 Next, as shown in FIG. 7 (c), the mounting base frame 18 of the upper frame 3 is fixed to the upper end surface of the column body 8 with screws 17, and the head member 19 is fitted on the mounting base frame 18. The state is as shown in FIG. Paste-like sealing material 38 is packed in the interior side of the glass fitting portion 16 formed in the mounting base frame 18, and the pasty sealing material 38 is also packed in the interior side of the glass fitting portion 22 of the lower frame 4. . Thereby, the fitting of the glass plate 6 is finished.

図３〜図５に示す手摺りのガラス板取付構造では、支柱２の目地枠９が支柱本体８と別体に形成されているが、図６には、支柱２の目地枠９が支柱本体８の室外側面に一体に形成されているガラス板取付構造を示す。即ち、支柱２の目地枠９は、基台部１０と、この基台部１０の幅方向中央部に突設された突条壁１２と、この凸条壁１２の先端部に断面略Ｔ字状を成すように突設された化粧縁１３とからなるものであるが、図６に示す支柱２の目地枠９は、基台部１０が支柱本体８の室外側面に一体に形成されたもので、この点以外は、図３〜図５に示す手摺りのガラス板取付構造と全く同じであるから同一部材に同一符号を付して説明を省略する。 3 to 5, the joint frame 9 of the support column 2 is formed separately from the support column body 8, but in FIG. 6, the joint frame 9 of the support column 2 is formed of the support column main body. 8 shows a glass plate mounting structure formed integrally with the outdoor side surface of 8. That is, the joint frame 9 of the support column 2 has a base portion 10, a ridge wall 12 projecting from the central portion in the width direction of the base portion 10, and a substantially T-shaped cross section at the tip of the ridge wall 12. The joint frame 9 of the column 2 shown in FIG. 6 is formed by integrally forming the base portion 10 on the outdoor side surface of the column body 8. Except for this point, the structure is the same as the handrail glass plate mounting structure shown in FIGS.

図３〜図５に示すように、目地枠９が支柱本体８とは別体に形成されている支柱２は、目地枠９の一部が破損した場合とか、ガラス板６の厚さが変更される場合には、目地枠９のみを取り換えればよいから、きわめて経済的である。また図６に示すように、目地枠９が支柱本体８の室外側面に一体に形成されている支柱２は、製作が容易であるから、支柱２のコストを安くできる。 As shown in FIGS. 3 to 5, in the support 2 in which the joint frame 9 is formed separately from the support body 8, when the joint frame 9 is partially damaged, the thickness of the glass plate 6 is changed. In this case, since only the joint frame 9 needs to be replaced, it is very economical. Further, as shown in FIG. 6, the column 2 in which the joint frame 9 is integrally formed on the outdoor side surface of the column main body 8 is easy to manufacture, so the cost of the column 2 can be reduced.

上述した図１〜図７に示すような実施形態の手摺りのガラス板取付構造は、ガラス取付枠５の支柱２が角筒状の支柱本体８とこれの室外側面に突設された目地枠９とからなり、目地枠９は、基台部１０と、これの幅方向中央部に突設されてその左右両側にガラス嵌合部１１を形成する突条壁１２と、これの先端部に断面略Ｔ字状を成すように突設された化粧縁１３とからなり、ガラス板６は、左右端部の室外面側に凹段部６ｏを有し、ガラス取付枠５にガラス板６を嵌装するにあたって、目地枠９の化粧縁１３に先付けビート１４を取り付け、左右に対向する両突条壁１２，１２のガラス嵌合部１１，１１間にガラス板６を上方より挿入し、ガラス板６の下端部及び上端部は、下枠４及び上枠３のガラス嵌合部２２，１６に夫々嵌め込んで保持するようにしたもので、ガラス板６の嵌め込み作業に外部足場を仮設することなく、簡単容易に行うことができると共に、目地枠９の突条壁１２の左右両側に形成されるガラス嵌合部１１へのガラス板６端部の嵌め込み深さを十分浅くすることが可能となり、これによってガラス板６の室外側から見た時の目地枠９の見附幅ｖは、図１を見れば分かるように、例えば１５ｍｍ程度と幅狭にすることができる。そしてまた、ガラス板６端部の凹段部６ｏに先付けビート１４を突入嵌合させることによって、目地枠９の化粧縁１３がガラス板６の室外面から出っ張らないようにしているから、目地枠９の見附幅ｖを幅狭にできることと相俟って、室外側から見た外観上の体裁、見栄えが良好となる。 The glass plate mounting structure of the handrail of the embodiment as shown in FIGS. 1 to 7 described above is a joint frame in which the column 2 of the glass mounting frame 5 protrudes from the square columnar column main body 8 and the outdoor side surface thereof. The joint frame 9 includes a base portion 10, a projecting wall 12 projecting from the center portion in the width direction thereof to form glass fitting portions 11 on both right and left sides thereof, and a tip portion thereof. The glass plate 6 has a recessed step portion 6o on the outdoor surface side of the left and right end portions, and the glass mounting frame 5 is provided with the glass plate 6 with a decorative edge 13 projecting so as to have a substantially T-shaped cross section. In fitting, a leading beat 14 is attached to the decorative edge 13 of the joint frame 9, and the glass plate 6 is inserted between the glass fitting portions 11, 11 of both protruding wall 12, 12 facing left and right, and glass The lower end portion and the upper end portion of the plate 6 are fitted and held in the glass fitting portions 22 and 16 of the lower frame 4 and the upper frame 3, respectively. The glass fitting portions that are formed on the left and right sides of the ridge wall 12 of the joint frame 9 can be easily and easily performed without temporarily setting an external scaffold for the fitting work of the glass plate 6. 11, the fitting depth of the end of the glass plate 6 can be made sufficiently shallow, so that the apparent width v of the joint frame 9 when seen from the outdoor side of the glass plate 6 can be seen from FIG. For example, the width can be as narrow as about 15 mm. Further, since the leading beat 14 is inserted and fitted into the concave step portion 6o at the end of the glass plate 6 so that the decorative edge 13 of the joint frame 9 does not protrude from the outdoor surface of the glass plate 6, the joint frame Combined with the fact that the attachment width v of 9 can be made narrow, the appearance and appearance of the exterior viewed from the outdoor side are improved.

また、このガラス板取付構造によれば、ガラス板６に加わる風圧による荷重は、左右に対向する目地枠９，９と上枠３と下枠４との４辺で受けるため、通常のシール目地の場合よりもガラス板の厚さを薄くすることができる。即ち、シール目地の場合は、シリコン等のシール材がガラス板の端面に接着することによってガラス板を保持することから、ガラス板の厚さが相当に厚くないと、十分な保持力が得られないが、本発明のガラス板取付構造では、ガラス板６の上端部及び下端部は、上枠３のガラス嵌合部１６及び下枠４のガラス嵌合部２２で夫々確実に保持し、ガラス板６の左右端部は、目地枠９の化粧縁１３に取り付けた先付けビート１４をガラス板端部の凹段部６ｏに嵌合させるから、ガラス板６が比較的薄くても、凹段部６ｏに嵌合する先付けビート１４によってガラス板６の左右端部を十分に保持できる。 Further, according to this glass plate mounting structure, the load due to the wind pressure applied to the glass plate 6 is received by the four sides of the joint frames 9 and 9, the upper frame 3 and the lower frame 4 facing left and right. In this case, the thickness of the glass plate can be reduced. That is, in the case of a seal joint, since a sealing material such as silicon adheres to the end surface of the glass plate, the glass plate is held, so that a sufficient holding force can be obtained unless the glass plate is considerably thick. However, in the glass plate mounting structure of the present invention, the upper end portion and the lower end portion of the glass plate 6 are securely held by the glass fitting portion 16 of the upper frame 3 and the glass fitting portion 22 of the lower frame 4, respectively. The left and right ends of the plate 6 are fitted to the concave step 6o at the end of the glass plate because the leading beat 14 attached to the decorative edge 13 of the joint frame 9 is fitted to the concave step 6o even if the glass plate 6 is relatively thin. The left and right ends of the glass plate 6 can be sufficiently held by the tipping beats 14 fitted to 6o.

また、この手摺りにおいて、各支柱２の目地枠９は、図２及び図５に示されるように、下枠４の端部が位置する部分より下方が支柱本体８から切除されているため、下枠４の取付けが容易になると共に、外観上の体裁がより一層良好となる。 Further, in this handrail, the joint frame 9 of each support column 2 is cut away from the support body 8 below the portion where the end of the lower frame 4 is located, as shown in FIGS. The attachment of the lower frame 4 is facilitated, and the appearance on the appearance is further improved.
