Description

【0001】
【発明の属する技術分野】
この発明は、リブガラスを支持するための支持構造に関する。
【0002】
【従来の技術】
一般に、面ガラス(板ガラス)を外壁として用いた建築物においては、面ガラスが室外の負圧によって室外側に引っ張られる。そこで、面ガラスを補強するためにリブガラスが用いられている。リブガラスは、方立の室外側を向く前面部に支持されており、面ガラスに直接に又は他の部材を介して接している。したがって、面ガラスが室外の負圧によって室外側に引っ張られると、その引っ張り力をリブガラスが受け、さらにリブガラスを介して方立が受ける。これによって、面ガラスが補強されている。
【0003】
従来、リブガラスを方立に支持させる場合には、方立の前面部に水平に延びるボルトを設け、このボルトをリブガラスに形成された貫通孔に挿通する。そして、ボルトに螺合されたナットを締め付けることにより、リブガラスを方立に固定するようにしていた。
【0004】
【発明が解決しようとする課題】
上記従来の支持構造では、リブガラスにボルトを挿通するための貫通孔が形成されているため、リブガラスの強度が低下する。しかも、貫通孔の内周面にはリブガラスの自重がのみならず、室内の圧力による荷重がそれぞれボルトを介して作用する。このため、リブガラスとしては強度の高い強化ガラスが用いざるを得なかった。強化ガラスは高価であるため、建築物の製造費が高騰するという問題があった。
【0005】
【課題を解決するための手段】
この発明は、強化ガラスのような高価なものでなく、フロートガラスのような安価なガラスをリブガラスとして用いることができるような支持構造を提供することを目的とするものであり、方立の室外側を向く前面に沿って上下に配置されリブガラスを方立に支持させるためのリブガラスの支持構造において、
上記方立の前面部に、上記リブガラスの下端部が載置される載置部を設けるとともに、上記リブガラスを室内側から室外側へ向って移動不能に保持する保持部を設けたことを特徴としている。
この場合、上記方立が、長手方向を上下方向に向けて配置された方立本体と、この方立本体の前面部に弾性部材を介して左右方向へ移動可能に連結された可動部材とを備え、上記載置部及び保持部が上記可動部材に設けられていることが。望ましい。上記保持部の内部には上記リブガラスの下端部及び載置部を収容する収容部が設けられていることが望ましい。
【0006】
【発明の実施の形態】
以下、この発明の一実施の形態について図1〜図8を参照して説明する。
図1及び図2は、この発明に係るリブガラスの支持構造が採用された建築物を示す図であり、図1は当該建築物を室外O側から見た正面図、図2は側断面図である。図2において符号Fは躯体の床スラブであり、符号Cは天井である。
【0007】
床スラブFの室外O側の端部には、長手方向を上下に向けた方立1が設けられている。方立1は、床スラブFから上方へ突出する上端部を除き、大部分が床スラブFとその階下の天井Cとの間に配置され、居住空間からはほとんど見えない。したがって、方立1を大型にしても室内Iの美観を損ねたり、室内I側から室外O側への視界を妨げることがほとんどない。そこで、方立1としては、室内外方向における幅が広く、強度の高いものが用いられている。
【0008】
図5及び図6に示すように、方立1は、固定部材11、室内I側から室外O側へ向って順次配置された中間部材12、可動部材13および支持部材14を有している。固定部材11は、断面長方形の筒状をなすものであり、その長手方向を上下に向けて床スラブF(図2参照)に固定されている。中間部材12は、固定部材11の室外O側を向く前面に固定されている。固定部材11と中間部材12とによって方立本体が構成されている。
【0009】
可動部材13は、中間部材12に弾性部材15を介して左右方向へ所定範囲移動可能に連結されている。図8に示すように、可動部材13の上下方向における中間部には、切欠き部13aが形成されている。この切欠き部13aの下方を向く面13bは、中間部材12に固定された支持駒16に載置されている。これにより、可動部材13が中間部材12に下方へ移動不能に支持されている。
【0010】
上記支持部材14は、図5及び図6に示すように、可動部材13に左右方向及び室内I側から室外O側へ向う方向へ移動不能に係合されている。支持部材14は、可動部材13に対して上下方向へは移動可能に係合しているが、図8に示すように、支持部材14の上下方向における中間部には切欠き部14aが形成されており、切欠き14aの下方を向く面が支持駒16に載置されている。したがって、支持部材14は、可動部材13と共に中間部材12に下方へ移動不能に支持されている。
【0011】
図2及び図3に示すように、方立1の上端部には、左右方向へ水平に延びる上横支持枠2が支持されている。また、図2及び図4に示すように、方立1の下端部には、左右方向へ水平に延びる下横支持枠3が配置されている。上横支持枠2及び下横支持枠3は、いずれもの前後方向における幅が方立1の中間部材12、可動部材13及び支持部材14の前後方向における合計幅とほぼ同一になっている。
【0012】
左右に隣接する二つの方立1,1と、この方立1,1の上下に設けられた上横支持枠2及び下横支持枠3とによって四角形の枠体が形成されている。そして、この四角形の枠体によって外壁となる面ガラス4が支持されている。この場合、面ガラス4の下端部は、図4に示すように、下横支持枠3によって支持されており、面ガラス4の上端部は、図3に示すように、上横支持枠2によって支持されている。面ガラス4の前面及び背面と上下の横支持枠2,3との各間には、シーリング材S1,S2が設けられている。図5及び図6に示すように、面ガラス4の左右の両側部は、支持部材14の室外O側に形成された左右に突出する挟持板部14aと中間部材12とによりシーリング材S1,S2を介して挟持されている。また、面ガラス4より室内I側には、耐火ボードBが配置されており、この耐火ボードBも方立1と上下の横支持枠2,3とによって構成される枠体によって支持されている。面ガラス4と耐火ボードBとによって二重壁構造が構成されている。
【0013】
図2〜図4及び図7に示すように、上下に隣接する二つの方立1,1のうち、下側の方立1の上端部に設けられた上横支持枠2と、上側の方立1の下端部に設けられた下横支持枠3との間には、縦支持枠5(図7参照)が設けられている。縦支持枠5は、上下の横支持枠2,3とほぼ同一の前後方向の幅を有し、横支持枠2,3と前後方向において同一位置に配置されている。したがって、縦支持枠5は、方立1の中間部材12、可動部材13及び支持部材14と上下方向においてほぼ一直線上に並んでいる。
【0014】
左右に隣接する二つの縦支持枠5,5とその上下に配置された横支持枠2,3とによって四角形の枠体が形成されており、この枠体によって外壁となる面ガラス6,6が支持されている。面ガラス6,6は、それらの間に密閉空間が形成されるよう、互いに若干離れ、かつ平行に配置されている。二つの面ガラス6,6のうち、外側の面ガラス6は、面ガラス4と室内外方向において同一位置に配置されている。面ガラス6は、1枚だけ設けられることもある。
【0015】
図3に示すように、面ガラス6,6の下端部は上横支持枠2によって支持されており、図4に示すように、面ガラス6,6の上端部は下横支持枠3によって支持されている。面ガラス6,6間および各面ガラス6と上下の横支持枠2,3との各間には、シーリング材S3,S4,S5が配置されている。図7に示すように、面ガラス6,6の両側部は、縦支持枠5の室内I側に形成された断面四角形の筒上状をなす基部51と、縦支持枠5の室外O側の端部に形成された左右に突出する挟持板部52とにより、シーリング材S3,S4,S5を介して挟持されている。縦支持枠5の挟持板部52は、方立1の挟持板部14aと室内外方向において同一位置に配置されている。
【0016】
上記のように、縦支持枠5の室内外方向の幅は、方立1の中間部材12、可動部材13及び支持部材14の室内外方向の合計幅とほぼ同一であり、方立1の全幅より固定部材11の分だけより狭くなっている。これは、室内の居住空間を狭くしないようにし、かつ室内Iから室外Oを見たとき、特に斜めに見たときに視界を大きく狭めることがないようにするためである。しかし、縦支持枠5の室内外方向の幅を狭くすると、同方向における縦支持枠5の強度が方立1より大幅に低くなってしまう。このため、面ガラス6が室外Oの負圧によって室外O側へ引っ張られると、縦支持枠5の上下方向における中間部が室外O側へ膨出するように変形し、それに対応して面ガラス6の上下方向の中央部が室外O側へ向って膨出するように変形するおそれがある。そこで、面ガラス6を補強する必要があり、補強手段としてリブガラス7が用いられている。この場合、リブガラス7は、図5〜図7に示すように、2枚張り合わせて用いられているが、1枚だけ用いられることもある。
【0017】
なお、室外Oの負圧による引っ張り力は、面ガラス6を介して上下の横支持枠2,3にも作用するが、面ガラス6の左右方向長さが上下方向の長さより短いので、面ガラス6の左右方向における中間部が室外O側へ膨出する点についてはほとんど問題になることがない。また、面ガラス4については、その上下左右の長さが短い上、両側部が方立1によって支持されているので、室外Oの負圧によって面ガラス4が室外O側へ膨出することはほとんどない。
【0018】
リブガラス7は、次のようにして方立1に支持されている。図5及び図6に示すように、支持部材14の室O側の端部には、室外O側に突出する突条14bが形成されている。この突条14bは、支持部材14の上端から下端まで延びており、その上下方向の中間部には載置部材(載置部)8が固定されている。一方、リブガラス7は、その長手方向を上下方向に、幅方向を室内外方向に向けて配置されており、その下端面が載置部材8の上面に載置されている。したがって、リブガラス7の重量は、載置部材8を介して方立1に支持されている。
【0019】
図3、図4及び図6に示すように、支持部材14の挟持板部14a、14aの室外O側を向く各前面には、室外O側へ突出する保持板部14cがそれぞれ形成されている。二つの保持板部14c,14cは、左右方向に互いに離れ、かつ互い平行に上下方向に延びている。二つの保持板部14c,14cの左右方向の間隔は、2枚のリブガラス7,7の合計厚さとほぼ同一になっている。そして、保持板部14c,14c間にリブガラス7,7の室内I側の側部が嵌め込まれることにより、リブガラス7が方立1に左右方向へ移動不能に支持されている。
【0020】
各保持板部14cの上下方向における中間部には、切欠き部14dが形成されている。この切欠き部14dは、その上下方向のほぼ中央部に上記載置部材8が位置するように配置されている。切欠き部14dには、保持部材(保持部)9の室内I側の端部が挿入されている。保持部材9は、図5に示すように、一対の保持半体9A,9Bを組み立てることによって形成されており、その左右方向の幅は、一対の保持板部14c,14cの外側の間隔とほぼ同一になっている。そして、保持部材9の室内I側の側部が上記切欠き部14d,14dに硬質ゴム等からなるシーリング材S6を介して挿入されることにより、保持部材9が方立1の支持部材14に上下方向へ移動不能に支持されている。しかも、保持部材9の室内I側の側部は、支持部材14の突条14b及び挟持板部14aに室内外方向及び左右方向へ移動不能に係合している。この結果、保持部材9は、支持部材14と一体に挙動するようになっている。
【0021】
保持部材9には、その上面から下面まで貫通する収容部91が形成されている。この収容部91には、載置部材8が収容されるとともに、この載置部8に載置されたリブガラス7,7の下端部、および載置部8の下側に配置されたリブガラス7,7の上端部が室内外方向及び左右方向へ移動不能に挿入されている。これにより、リブガラス7,7が保持部材9を介して方立1の支持部材14に室内外方向及び左右方向へ移動不能に連結され、同方向に対しては支持部材14と一体に挙動するようになっている。
【0022】
リブガラス7は、突条14bに固定された載置部材8の上面に載置されているので、縦支持枠5の挟持板部52に対しては、突条14bの突出量分だけ室外O側に離れているが、リブガラス7と縦支持枠5の挟持板部52との間には、比較的硬質のゴム等からなるシーリング材S7が充填されている。したがって、リブガラス7は、面ガラス6に作用する室外Oの負圧を縦支持枠5の挟持板部52及びシーリング材S7を介して支持しており、室外O側の負圧による荷重は、リブガラス7の保持部材9と接する室内I側及び室外O側の側面に作用している。なお、符号S8は、比較的軟質なシーリング材である。
【0023】
リブガラス7に対する上記の支持構造によれば、リブガラス7の自重をその下面で受け、室外Oの負圧を側面で受けている。つまり、リブガラス7は、その自重と室外Oの負圧とを異なる面で受けている。しかも、リブガラス7には、ボルトを挿通するための貫通孔が形成されていない。したがって、リブガラス7としてフロートガラス等の安価な板ガラスを用いることができる。
【0024】
また、載置部材8及び保持部材9が支持部材14及び可動部材13を介して中間部材12(方立本体)に左右方向へ移動可能に支持されているから、地震等によって建築物に層間変位が発生した場合には、リブガラス7の上端部又は下端部が層間変位に追随して左右方向へ変位することができる。よって、リブガラス7が層間変位によって破断されるのを防止することができる。
【0025】
【発明の効果】
以上説明したように、この発明によれば、リブガラスとしてフロートガラス等の安価なガラスを用いることができるという効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a support structure for supporting rib glass.
[0002]
[Prior art]
Generally, in a building using a surface glass (plate glass) as an outer wall, the surface glass is pulled to the outdoor side by the negative pressure outside the room. Therefore, rib glass is used to reinforce the face glass. The rib glass is supported by the front part facing the vertical outdoor side, and is in contact with the surface glass directly or through another member. Therefore, when the surface glass is pulled outside by the outdoor negative pressure, the rib glass receives the pulling force and further receives the vertical through the rib glass. Thereby, the surface glass is reinforced.
[0003]
Conventionally, when the rib glass is supported in a vertical manner, a bolt extending horizontally is provided on the front surface portion of the vertical wall, and the bolt is inserted through a through hole formed in the rib glass. Then, the rib glass is fixed in a vertical manner by tightening a nut screwed into the bolt.
[0004]
[Problems to be solved by the invention]
In the conventional support structure, since the through hole for inserting the bolt into the rib glass is formed, the strength of the rib glass is lowered. Moreover, not only the rib glass has its own weight on the inner peripheral surface of the through-hole, but also a load due to the pressure in the room acts through the bolts. For this reason, high-strength tempered glass has to be used as the rib glass. Since the tempered glass is expensive, there is a problem that the manufacturing cost of the building increases.
[0005]
[Means for Solving the Problems]
An object of the present invention is to provide a support structure that can use inexpensive glass such as float glass as rib glass instead of expensive glass such as tempered glass. In the rib glass support structure for vertically supporting the rib glass disposed vertically along the front surface facing the outside,
In addition to providing a mounting portion on which the lower end portion of the rib glass is mounted on the front surface of the vertical wall, a holding portion that holds the rib glass immovably from the indoor side toward the outdoor side is provided. Yes.
In this case, the above-mentioned vertical includes a vertical main body arranged with its longitudinal direction directed in the vertical direction, and a movable member connected to the front surface of the vertical main body through an elastic member so as to be movable in the left-right direction. The above-mentioned mounting portion and holding portion are provided on the movable member. desirable. It is desirable that an accommodating portion for accommodating the lower end portion and the placement portion of the rib glass is provided inside the holding portion.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
1 and 2 are views showing a building in which the rib glass support structure according to the present invention is adopted. FIG. 1 is a front view of the building as viewed from the outdoor O side, and FIG. 2 is a side sectional view. is there. In FIG. 2, the symbol F is a floor slab of a frame, and the symbol C is a ceiling.
[0007]
At the end of the floor slab F on the outdoor O side, a stand 1 having a longitudinal direction directed up and down is provided. Most of the verticals 1 are arranged between the floor slab F and the ceiling C below the floor slab F except for the upper end protruding upward from the floor slab F, and are hardly visible from the living space. Therefore, even if the stand 1 is made large, the aesthetic appearance of the room I is hardly impaired and the view from the room I side to the outdoor O side is hardly hindered. Therefore, as the stand 1, a material having a wide width in the indoor / outdoor direction and high strength is used.
[0008]
As shown in FIGS. 5 and 6, the stand 1 includes a fixed member 11, an intermediate member 12, a movable member 13, and a support member 14 that are sequentially arranged from the room I side toward the outdoor O side. The fixing member 11 has a cylindrical shape with a rectangular cross section, and is fixed to the floor slab F (see FIG. 2) with its longitudinal direction directed up and down. The intermediate member 12 is fixed to the front surface of the fixing member 11 facing the outdoor O side. A vertical body is constituted by the fixing member 11 and the intermediate member 12.
[0009]
The movable member 13 is connected to the intermediate member 12 via the elastic member 15 so as to be movable within a predetermined range in the left-right direction. As shown in FIG. 8, a cutout portion 13 a is formed in the middle portion of the movable member 13 in the vertical direction. A face 13 b facing downward of the notch 13 a is placed on a support piece 16 fixed to the intermediate member 12. Thereby, the movable member 13 is supported by the intermediate member 12 so as not to move downward.
[0010]
As shown in FIGS. 5 and 6, the support member 14 is engaged with the movable member 13 so as not to move in the left-right direction and in the direction from the indoor I side toward the outdoor O side. The support member 14 is engaged with the movable member 13 so as to be movable in the vertical direction. However, as shown in FIG. 8, a notch portion 14 a is formed in an intermediate portion in the vertical direction of the support member 14. The surface facing the lower side of the notch 14 a is placed on the support piece 16. Accordingly, the support member 14 is supported by the intermediate member 12 together with the movable member 13 so as not to move downward.
[0011]
As shown in FIGS. 2 and 3, an upper horizontal support frame 2 that extends horizontally in the left-right direction is supported on the upper end portion of the stand 1. As shown in FIGS. 2 and 4, a lower horizontal support frame 3 that extends horizontally in the left-right direction is disposed at the lower end of the stand 1. The upper lateral support frame 2 and the lower lateral support frame 3 have substantially the same width in the front-rear direction as the total width in the front-rear direction of the intermediate member 12, the movable member 13, and the support member 14 in the vertical direction 1.
[0012]
A quadrangular frame is formed by two vertical stands 1, 1 adjacent to the left and right, and an upper horizontal support frame 2 and a lower horizontal support frame 3 provided above and below the vertical stands 1, 1. And the surface glass 4 used as an outer wall is supported by this square frame. In this case, the lower end portion of the surface glass 4 is supported by the lower horizontal support frame 3 as shown in FIG. 4, and the upper end portion of the surface glass 4 is supported by the upper horizontal support frame 2 as shown in FIG. It is supported. Sealing materials S1 and S2 are provided between the front and back surfaces of the surface glass 4 and the upper and lower horizontal support frames 2 and 3, respectively. As shown in FIGS. 5 and 6, the left and right side portions of the surface glass 4 are sealed by the sandwiching plate portions 14 a formed on the outdoor O side of the support member 14 and the intermediate member 12 and the sealing materials S <b> 1 and S <b> 2. Is sandwiched through. Further, a fireproof board B is arranged on the room I side from the surface glass 4, and this fireproof board B is also supported by a frame body constituted by the vertical 1 and the upper and lower horizontal support frames 2 and 3. . The face glass 4 and the fireproof board B constitute a double wall structure.
[0013]
As shown in FIG. 2 to FIG. 4 and FIG. 7, the upper horizontal support frame 2 provided at the upper end of the lower side stand 1 among the two vertically adjacent stands 1 and 1, and the upper side A vertical support frame 5 (see FIG. 7) is provided between the lower horizontal support frame 3 provided at the lower end of the upright 1. The vertical support frame 5 has substantially the same width in the front-rear direction as the upper and lower horizontal support frames 2, 3 and is disposed at the same position in the front-rear direction as the horizontal support frames 2, 3. Therefore, the vertical support frame 5 is aligned with the intermediate member 12, the movable member 13, and the support member 14 in the vertical direction in a substantially straight line.
[0014]
A rectangular frame is formed by the two vertical support frames 5 and 5 adjacent to the left and right and the horizontal support frames 2 and 3 arranged above and below the vertical support frames 5 and 5. It is supported. The face glasses 6 and 6 are arranged slightly apart from each other and in parallel so that a sealed space is formed between them. Out of the two surface glasses 6 and 6, the outer surface glass 6 is disposed at the same position as the surface glass 4 in the indoor and outdoor direction. Only one face glass 6 may be provided.
[0015]
As shown in FIG. 3, the lower end portions of the face glasses 6 and 6 are supported by the upper horizontal support frame 2, and the upper end portions of the face glasses 6 and 6 are supported by the lower horizontal support frame 3 as shown in FIG. 4. Has been. Sealing materials S3, S4, and S5 are disposed between the surface glasses 6 and 6 and between each surface glass 6 and the upper and lower horizontal support frames 2 and 3, respectively. As shown in FIG. 7, both side portions of the face glasses 6 and 6 are formed on the indoor support I side of the vertical support frame 5 and have a base 51 having a rectangular cross section and an outdoor O side of the vertical support frame 5. It is clamped via sealing materials S3, S4, and S5 by a clamping plate portion 52 that is formed at the end and projects to the left and right. The sandwiching plate portion 52 of the vertical support frame 5 is disposed at the same position as the sandwiching plate portion 14a of the vertical 1 in the indoor / outdoor direction.
[0016]
As described above, the width of the vertical support frame 5 in the indoor / outdoor direction is substantially the same as the total width in the indoor / outdoor direction of the intermediate member 12, the movable member 13, and the support member 14 of the stand 1, and the full width of the stand 1. Further, it is narrower by the amount of the fixing member 11. This is to prevent the indoor living space from being narrowed and to prevent the field of view from being greatly narrowed when the outdoor O is viewed from the room I, particularly when viewed obliquely. However, if the width of the vertical support frame 5 in the indoor / outdoor direction is narrowed, the strength of the vertical support frame 5 in the same direction is significantly lower than that of the stand 1. For this reason, when the surface glass 6 is pulled to the outdoor O side by the negative pressure of the outdoor O, the intermediate portion in the vertical direction of the vertical support frame 5 is deformed so as to bulge to the outdoor O side, and the surface glass is correspondingly corresponding thereto. There is a possibility that the center portion in the vertical direction of 6 will be deformed so as to bulge toward the outdoor O side. Therefore, it is necessary to reinforce the surface glass 6, and the rib glass 7 is used as a reinforcing means. In this case, as shown in FIGS. 5 to 7, the rib glass 7 is used by bonding two sheets, but only one sheet may be used.
[0017]
The pulling force due to the negative pressure of the outdoor O also acts on the upper and lower horizontal support frames 2 and 3 via the surface glass 6, but the horizontal length of the surface glass 6 is shorter than the vertical length. There is almost no problem with respect to the point that the middle portion of the glass 6 in the left-right direction bulges to the outdoor O side. Moreover, about the surface glass 4, since the length of the upper and lower sides, right and left is short, since both sides are supported by the stand 1, the surface glass 4 does not bulge to the outdoor O side by the negative pressure of the outdoor O. rare.
[0018]
The rib glass 7 is supported on the vertical 1 as follows. As shown in FIGS. 5 and 6, a protrusion 14 b that protrudes to the outdoor O side is formed at the end of the support member 14 on the chamber O side. The protrusion 14b extends from the upper end to the lower end of the support member 14, and a mounting member (mounting portion) 8 is fixed to an intermediate portion in the vertical direction. On the other hand, the rib glass 7 is arranged with its longitudinal direction in the vertical direction and its width direction in the indoor / outdoor direction, and its lower end surface is placed on the upper surface of the placement member 8. Therefore, the weight of the rib glass 7 is supported on the vertical 1 via the mounting member 8.
[0019]
As shown in FIGS. 3, 4, and 6, holding plate portions 14 c that protrude toward the outdoor O side are formed on the front surfaces of the holding plate portions 14 a and 14 a of the support member 14 facing the outdoor O side. . The two holding plate portions 14c, 14c are separated from each other in the left-right direction and extend in the vertical direction in parallel with each other. The distance between the two holding plate portions 14c, 14c in the left-right direction is substantially the same as the total thickness of the two rib glasses 7, 7. And the rib glass 7 is supported by the stand 1 so that it cannot move to the left-right direction by fitting the side part by the side of the room | chamber I of the rib glass 7 and 7 between holding | maintenance board parts 14c and 14c.
[0020]
A notch portion 14d is formed at an intermediate portion in the vertical direction of each holding plate portion 14c. The notch portion 14d is arranged so that the placing member 8 is positioned at a substantially central portion in the vertical direction. The end of the holding member (holding portion) 9 on the room I side is inserted into the notch portion 14d. As shown in FIG. 5, the holding member 9 is formed by assembling a pair of holding halves 9A and 9B, and the width in the left-right direction is substantially equal to the distance between the outside of the pair of holding plate portions 14c and 14c. It is the same. And the side part by the side of the room | chamber I of the holding member 9 is inserted in the said notch parts 14d and 14d via the sealing material S6 which consists of hard rubber etc., The holding member 9 becomes the support member 14 of the upright 1 It is supported so that it cannot move vertically. In addition, the side of the holding member 9 on the side of the room I is engaged with the protrusion 14b and the holding plate part 14a of the support member 14 so as not to move in the indoor outdoor direction and the left-right direction. As a result, the holding member 9 behaves integrally with the support member 14.
[0021]
The holding member 9 is formed with an accommodating portion 91 that penetrates from the upper surface to the lower surface. The accommodation portion 91 accommodates the placement member 8, the rib glass 7 placed on the placement portion 8, and the rib glass 7 placed on the lower side of the placement portion 8. 7 is inserted so that it cannot move in the indoor / outdoor direction and the left / right direction. As a result, the rib glasses 7 and 7 are connected to the support member 14 of the vertical 1 through the holding member 9 so as to be immovable in the indoor and outdoor directions and in the left and right directions, and behave integrally with the support member 14 in the same direction. It has become.
[0022]
Since the rib glass 7 is mounted on the upper surface of the mounting member 8 fixed to the protrusion 14b, the rib glass 7 is placed on the outdoor O side by the protrusion amount of the protrusion 14b with respect to the sandwiching plate portion 52 of the vertical support frame 5. However, between the rib glass 7 and the sandwiching plate portion 52 of the vertical support frame 5, a sealing material S7 made of a relatively hard rubber or the like is filled. Therefore, the rib glass 7 supports the negative pressure of the outdoor O acting on the surface glass 6 via the sandwiching plate portion 52 and the sealing material S7 of the vertical support frame 5, and the load due to the negative pressure on the outdoor O side is the rib glass. 7 on the side surfaces of the indoor I side and the outdoor O side that are in contact with the holding member 9. Reference S8 is a relatively soft sealing material.
[0023]
According to the support structure for the rib glass 7, the weight of the rib glass 7 is received by the lower surface, and the negative pressure of the outdoor O is received by the side surface. That is, the rib glass 7 receives its own weight and the negative pressure of the outdoor O on different surfaces. Moreover, the rib glass 7 is not formed with a through hole for inserting a bolt. Therefore, an inexpensive plate glass such as float glass can be used as the rib glass 7.
[0024]
Moreover, since the mounting member 8 and the holding member 9 are supported by the intermediate member 12 (vertical main body) through the support member 14 and the movable member 13 so as to be movable in the left-right direction, the interlayer displacement is caused to the building by an earthquake or the like. When this occurs, the upper end or the lower end of the rib glass 7 can be displaced in the left-right direction following the interlayer displacement. Therefore, the rib glass 7 can be prevented from being broken by the interlayer displacement.
[0025]
【The invention's effect】
As described above, according to the present invention, there is an effect that inexpensive glass such as float glass can be used as the rib glass.
