Description

本発明は、ガラスの周縁部を保持する部材を備える建具に関する。 The present invention relates to a fitting provided with a member that holds the peripheral edge of the glass.

従来から、室内側に配置される金属製の先付金具と、室外側に配置される金属製の後付金具とで構成され、ガラスの一例としての複層ガラスの周縁部を保持する脱落防止部材を備えた建具は知られている(例えば、特許文献1参照)。先付金具は、框の見込み面に沿って配置される先付取付部と、先付取付部の一側縁部から直角方向に屈曲した先付保持部とが一体に成形されており、先付取付部が框に備えられた補強部材に取り付けられる。 Conventionally, it is composed of a metal front metal fitting arranged on the indoor side and a metal retrofit metal fitting placed on the outdoor side, and prevents falling off to hold the peripheral edge of double glazing as an example of glass. Joinery with members is known (see, for example, Patent Document 1). The tip fitting is formed by integrally forming a tip mounting part that is arranged along the prospective surface of the stile and a tip holding part that is bent in the direction perpendicular to one side edge of the tip mounting part. The attachment part is attached to the reinforcing member provided on the stile.

後付金具は、框の見込み面に沿って配置される後付取付部と、後付取付部の一側縁部から直角方向に屈曲した後付保持部とが一体に成形されており、框に先付金具が取り付けられている状態で複層ガラスを配置し、その後、後付取付部を先付取付部に係合させることによって框に取り付けられる。後付取付部が先付取付部に係合することにより、先付保持部と後付保持部とにより複層ガラスの周縁部が挟持される。 The retrofit metal fitting is integrally formed with a retrofit mounting portion arranged along the prospective surface of the stile and a retrofit holding portion bent in a direction perpendicular to one side edge of the retrofit mounting portion. The double glazing is arranged with the front fitting attached to the stile, and then the retrofit is attached to the stile by engaging the retrofit with the front attachment. When the retrofit mounting portion engages with the pre-attached mounting portion, the peripheral portion of the double glazing is sandwiched between the pre-attached holding portion and the retrofit holding portion.

特開2016−23484号公報Japanese Unexamined Patent Publication No. 2016-23484

上記従来の建具では、框と、框に係合される押縁とにより複層ガラスの周縁部を収容しており、框側に先付金具を固定し、押縁を係合する前に後付金具を先付金具に係合させ、その後に押縁を框に係合させている。このとき、後付金具と先付金具との係合部は、複層ガラスを構成する2枚のガラス板のうちの押縁側のガラス板の端面とほぼ対向する位置に配置されている。このため、建具が押縁側から火炎に晒されると、後付金具の下側に位置する框が溶融されることにより、後付金具の押縁側が落ち込み先付金具との係合が外れて複層ガラスが脱落する虞がある。また、建具に備えられるガラスとしては、トリプルガラスのように3枚以上のガラス板が一体化されて重量が大きなガラス板のユニットを有するものもあり、従来の建具のように、押縁側のガラス板の端面とほぼ対向する位置にて後付金具と先付金具とが係合している場合には、ガラス板のユニットが、より脱落しやすいという課題がある。 In the above-mentioned conventional fitting, the peripheral portion of the double glazing is accommodated by the stile and the ridge engaged with the stile, and the front fitting is fixed to the stile side, and the rear fitting is attached before the ridge is engaged. Is engaged with the front fitting, and then the ridge is engaged with the stile. At this time, the engaging portion between the retrofit metal fitting and the front metal fitting is arranged at a position substantially opposite to the end surface of the glass plate on the ridge side of the two glass plates constituting the double glazing. For this reason, when the fitting is exposed to flame from the ridge side, the stile located under the retrofit fitting is melted, so that the ridge side of the retrofit fitting falls and the engagement with the tip fitting is disengaged. There is a risk that the double glazing will fall off. Further, as the glass provided in the fitting, there is a glass having a heavy glass plate unit in which three or more glass plates are integrated like triple glass, and the glass on the ridge side like the conventional fitting. When the retrofit metal fitting and the front metal fitting are engaged at a position substantially opposite to the end surface of the plate, there is a problem that the unit of the glass plate is more likely to fall off.

本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、3枚以上のガラス板を有しつつもガラス板が脱落し難い建具を提供することにある。 The present invention has been made in view of such a problem, and an object of the present invention is to provide a fitting having three or more glass plates but the glass plates are hard to fall off.

かかる目的を達成するための主たる発明は、耐熱強化ガラスを含む3枚以上のガラス板を備え屋内外を仕切るガラスユニットと、前記ガラスユニットを保持し、内周側に前記ガラスユニットの周縁部を収容するガラス収容部を有する枠体と、前記ガラス収容部に設けられ、前記ガラスユニットの屋内または屋外に臨む一方の面と対面する第一対面部を有し前記枠体に固定される固定金具と、前記ガラス収容部に設けられ、前記ガラスユニットの屋内または屋外に臨む他方の面と対面する第二対面部を有し前記固定金具に係止される係止金具と、を有し、前記係止金具が前記固定金具に係止されている位置は、前記ガラスユニットが有するガラス板のうちの前記第二対面部側から2枚目に位置する前記ガラス板よりも前記第一対面部側に位置していることを特徴とする建具である。
本発明の他の特徴については、本明細書及び添付図面の記載により明らかにする。

Heat resistant tempered glass 21 is provided.

FIX枠3は、合成樹脂製の押し出し成形材でなりガラスユニット2の上に位置する上の枠材30、ガラスユニット2の下に位置する下の枠材30、及び、ガラスユニット2の左右に位置する左右の縦の枠材30をなす4本の枠材30が矩形状に接合された枠本体31と、各枠材30に嵌合される押縁32と、を有している。 The FIX frame 3 is made of an extruded material made of synthetic resin, and is located on the upper frame material 30 located above the glass unit 2, the lower frame material 30 located below the glass unit 2, and on the left and right sides of the glass unit 2. It has a frame body 31 in which four frame members 30 forming the left and right vertical frame members 30 are joined in a rectangular shape, and a ridge 32 fitted to each frame member 30.

4本の枠材30は、長尺の成形材を所定の長さに切断して形成されているため同一の断面形状をなしている。各枠材30の端部は長手方向に対して45度の角度をなすように切断され、互いに隣り合う枠材30の端部同士を突き合わせた状態で溶着し矩形状の枠本体31が形成されている。各枠材30の断面形状は同一なので、ここでは、図面にて下の枠材30を示して枠構造を説明する。以下の説明では、各枠材30に共通する説明となるように、下の枠材30の上側を、枠本体31の内周側(以下、内周側という)とし、下の枠材30の下側を枠本体31の外周側(以下、外周側という)として説明する。 The four frame members 30 have the same cross-sectional shape because they are formed by cutting a long molding material to a predetermined length. The ends of each frame member 30 are cut so as to form an angle of 45 degrees with respect to the longitudinal direction, and the ends of the frame members 30 adjacent to each other are welded to each other so as to form a rectangular frame body 31. ing. Since the cross-sectional shape of each frame member 30 is the same, here, the frame structure will be described by showing the frame member 30 below in the drawings. In the following description, the upper side of the lower frame material 30 is referred to as the inner peripheral side (hereinafter referred to as the inner peripheral side) of the frame main body 31 so as to be a common explanation for each frame material 30, and the lower frame material 30 The lower side will be described as the outer peripheral side of the frame main body 31 (hereinafter, referred to as the outer peripheral side).

下の枠材30は、図4に示すように、ガラスユニット2がセッティングブロック4を介して載置され当該ガラスユニット2の端面2bと対向する枠見込み面部30aと、枠見込み面部30aの屋内側にて内周側に突出する枠内周突出部30bと、枠見込み面部30aの屋外側に設けられ押縁32が嵌合される枠押縁嵌合部30cと、枠見込み面部30aの外周側に間隔を空けて対向する枠外周対向面部30dと、枠外周対向面部30dから外周側に延出されて躯体6に固定される躯体固定部30eと、を有している。 As shown in FIG. 4, the lower frame member 30 has a frame prospective surface portion 30a on which the glass unit 2 is placed via the setting block 4 and faces the end surface 2b of the glass unit 2, and an indoor side of the frame prospective surface portion 30a.

A frame finding surface of 30 g is formed at the position.

下の枠材30の枠見込み面部30aと枠外周対向面部30dとの間には、長手方向に貫通する枠中空部30hが設けられている。枠中空部30hは、枠見込み面部30aの見込み方向における両端部から外周側に延出されて枠外周対向面部30dと繋がる2つの枠連結壁部30iによって仕切られてほぼ矩形状をなしている。2つの枠連結壁部30iは、見込み方向において互いに対向している。 A frame hollow portion 30h penetrating in the longitudinal direction is provided between the frame prospective surface portion 30a of the lower frame member 30 and the frame outer peripheral facing surface portion 30d. The frame hollow portion 30h has a substantially rectangular shape and is partitioned by two frame connecting wall portions 30i extending from both ends of the frame prospective surface portion 30a in the prospective direction to the outer peripheral side and connecting to the frame outer peripheral facing surface portion 30d. The two frame connecting wall portions 30i face each other in the prospective direction.

枠中空部30h内には、長手方向に沿い全長にわたってアルミニウム合金製の押し出し成形材でなる補強部材8が設けられている。ここで、枠見込み面部30aが、FIX枠3において枠中空部30hを形成し、ガラス収容部3a側に位置する内周板部に相当し、枠外周対向面部30dが、FIX枠3において枠中空部30hを形成し、躯体固定部30e側に位置する外周板部に相当する。補強部材8については後述する。 A reinforcing member 8 made of an extruded aluminum alloy material is provided in the hollow frame portion 30h along the longitudinal direction over the entire length. Here, the frame prospective surface portion 30a forms the frame hollow portion 30h in the FIX frame 3, and corresponds to the inner peripheral plate portion located on the glass accommodating portion 3a side, and the frame outer peripheral facing surface portion 30d is the frame hollow in the FIX frame 3. The portion 30h is formed and corresponds to the outer peripheral plate portion located on the skeleton fixing portion 30e side. The reinforcing member 8 will be described later.

枠押縁嵌合部30cは、枠見込み面部30aよりも屋外側に設けられ、枠見込み面部30aよりも外周側に窪んで押縁32の嵌合片32aが嵌合される。枠押縁嵌合部30cは、屋外側の枠連結壁部30iの屋外側にて枠見込み面部30aよりも外周側に位置する枠底部30jを有する2つの枠凹部30k、30lのうちの屋外側の枠凹部30kである。屋内側の枠凹部30lの屋内側の縁30mは、枠見込み面部30aの屋外側の縁と繋がり、外周面が円弧状をなしている。 The frame ridge fitting portion 30c is provided on the outdoor side of the frame prospective surface portion 30a, and is recessed on the outer peripheral side of the frame prospective surface portion 30a to fit the fitting piece 32a of the ridge 32. The frame ridge fitting portion 30c is located on the outdoor side of the two frame recesses 30k and 30l having a frame bottom portion 30j located on the outer side of the frame prospective surface portion 30a on the outdoor side of the frame connecting wall portion 30i on the outdoor side. The frame recess is 30k. The indoor side edge 30m of the indoor side frame recess 30l is connected to the outdoor side edge of the frame prospective surface portion 30a, and the outer peripheral surface has an arc shape.

押縁32は、嵌合片32aが枠押縁嵌合部30cに嵌合された状態で、枠内周突出部30bと見込み方向に対向し、枠本体31とともにガラスユニット2の周縁部が収容されるガラス収容部3aを形成する。すなわち、ガラス収容部3aは、枠本体31に嵌合された押縁32と、屋内側の枠凹部30lと、枠見込み面部30aと、枠内周突出部30bとにより囲まれた空間である。 The ridge 32 faces the inner peripheral protrusion 30b of the frame in the prospective direction in a state where the fitting piece 32a is fitted to the frame ridge fitting portion 30c, and the peripheral edge portion of the glass unit 2 is accommodated together with the frame body 31. A glass accommodating portion 3a is formed. That is, the glass accommodating portion 3a is a space surrounded by a ridge 32 fitted to the frame main body 31, a frame recess 30l on the indoor side, a frame prospective surface portion 30a, and a frame inner peripheral protrusion 30b.

ガラス収容部3aに周縁部が収容されたガラスユニット2は、ガラス収容部3aに設けられるセッティングブロック4により面内方向の位置が規制されてガラス保持金具9に保持され、枠内周突出部30bのビード7と、押縁32の先端に設けられたビード32bとにより挟持される。このとき、ガラスユニット2の屋内側の面2cは、枠内周突出部30bのビード7に押圧され、枠内周突出部30bの枠見付け面30gと見込み方向に間隔を空けて配置されている。また、ガラスユニット2の屋外側の面2dは、枠見込み面部30aと屋内側の枠凹部30lとの境界付近に位置している。ガラス保持金具9については後述する。 The glass unit 2 whose peripheral edge is accommodated in the glass accommodating portion 3a is held by the glass holding metal fitting 9 whose position in the in-plane direction is restricted by the setting block 4 provided in the glass accommodating portion 3a, and the frame inner peripheral protrusion 30b. It is sandwiched between the bead 7 and the bead 32b provided at the tip of the ridge 32. At this time, the indoor side surface 2c of the glass unit 2 is pressed by the bead 7 of the frame inner peripheral protrusion 30b, and is arranged at a distance from the frame finding surface 30g of the frame inner peripheral protrusion 30b in the prospective direction. .. Further, the outdoor side surface 2d of the glass unit 2 is located near the boundary between the frame prospective surface portion 30a and the indoor side frame recess 30l. The glass holding metal fitting 9 will be described later.

躯体固定部30eは、枠外周対向面部30dにおいて枠中空部30hとは反対側となる外周面側から外周方向に延出されており、枠中空部30hを仕切る屋外側の枠連結壁部30iより僅かに屋内側に設けられている。このため、ガラス収容部3aに周縁部が収容されたガラスユニット2は、最も屋外側に位置するガラス板(以下、最外ガラス板という)20が、躯体固定部30eを上方に延長した位置に配置されており、最外ガラス板20よりも屋内側の部位が躯体6上に位置している。 The skeleton fixing portion 30e extends in the outer peripheral direction from the outer peripheral surface side opposite to the frame hollow portion 30h in the frame outer peripheral facing surface portion 30d, and extends from the frame connecting wall portion 30i on the outdoor side that partitions the frame hollow portion 30h. It is slightly installed on the indoor side. Therefore, in the glass unit 2 in which the peripheral edge portion is housed in the glass accommodating portion 3a, the glass plate 20 located on the outermost side (hereinafter referred to as the outermost glass plate) 20 is located at a position where the skeleton fixing portion 30e is extended upward. It is arranged, and the portion on the indoor side of the outermost glass plate 20 is located on the skeleton 6.

下の枠材30の躯体固定部30eは、屋外側から進入するビス33により躯体6に固定されるが、上及び縦の枠材30の躯体固定部30eは、図2、図3に示すように、補強金具5と共に屋外側から進入するビス33により躯体6に固定される。尚、下の枠材30の躯体固定部30eも補強金具5と共に屋外側から進入するビス33により躯体6に固定されていても構わない。 The skeleton fixing portion 30e of the lower frame member 30 is fixed to the skeleton 6 by a screw 33 entering from the outdoor side, and the skeleton fixing portion 30e of the upper and vertical frame members 30 is as shown in FIGS. In addition, it is fixed to the skeleton 6 by a screw 33 that enters from the outdoor side together with the reinforcing metal fitting 5. The skeleton fixing portion 30e of the lower frame member 30 may also be fixed to the skeleton 6 by a screw 33 entering from the outdoor side together with the reinforcing metal fitting 5.

枠中空部30hに設けられている補強部材8は、枠見込み面部30aと対向し見込み方向のほぼ全域に設けられる対向板部としての見込み面補強部8aと、見込み面補強部8aから外周方向に延出された2つの延出補強部8bと、を有している。見込み面補強部8aは、枠見込み面部30aの反対側に設けられる後述する固定金具90を固定するビス34が螺合可能な厚みを有している。見込み面補強部8aの枠見込み面部30a側の面には、長手方向に沿う凹部8cが屋内側の端部近傍と、見込み方向における中央より屋外側寄りの部位との2カ所に設けられており、凹部8c内には、加熱発泡材10が設けられている。 The reinforcing member 8 provided in the hollow frame portion 30h is opposed to the frame prospective surface portion 30a and is provided in almost the entire area in the prospective direction. It has two extension reinforcing portions 8b, which are extended. The prospective surface reinforcing portion 8a has a thickness to which a screw 34 for fixing a fixing metal fitting 90, which will be described later, provided on the opposite side of the prospective surface portion 30a of the frame can be screwed.

A locking hole 90d for locking the locking piece 91b is provided at a position biased toward the indoor side in the prospective direction.

屋内内周延出部90cは、ガラスユニット2における周縁部の屋内側面と対向する部位であり、左右方向における両端部から延出された屋内延出片90eが設けられている。屋内延出片90eは、屋内内周延出部90cから左右方向に離れるに連れて屋内側に位置する傾斜を有している。この傾斜は、屋内内周延出部90cに沿う仮想線Lに対して鋭角をなしている。 The indoor inner peripheral extending portion 90c is a portion of the glass unit 2 facing the indoor side surface of the peripheral portion, and indoor extending pieces 90e extending from both ends in the left-right direction are provided. The indoor extension piece 90e has an inclination that is located on the indoor side as the indoor extension piece 90e is separated from the indoor inner peripheral extension portion 90c in the left-right direction. This inclination makes an acute angle with respect to the virtual line L along the indoor inner peripheral extension 90c.

固定金具90は、屋内延出片90eの先端が、枠内周突出部30bの枠見付け面30gに当接する状態で枠固定部90aが枠見込み面部30aに固定される。このとき、ガラスユニット2の屋内側の面2cが屋内内周延出部90cに当接すると、枠内周突出部30bのビード7がガラスユニット2との間で押圧されて枠本体31とガラスユニット2との間が止水される。 In the fixing bracket 90, the frame fixing portion 90a is fixed to the frame prospective surface portion 30a in a state where the tip of the indoor extension piece 90e is in contact with the frame finding surface 30g of the frame inner peripheral protrusion 30b.

The outdoor inner peripheral extending portion 91c is a portion of the glass unit 2 facing the outdoor side surface 2d of the peripheral portion, and a cushioning material 11 made of synthetic resin is provided on the indoor side.

FIX枠3にガラスユニット2を取り付ける方法は、まず、各枠材30にセッティングブロック4及び固定金具90を取り付ける。セッティングブロック4は、下の枠材30には、載置するだけでも構わない。取り付けられた固定金具90は、屋内延出片90eの先端が、枠材30の枠見付け面30gに当接している。この状態で、固定金具90の屋内内周延出部90cの屋外側の面が、ガラスユニット2の屋内側の面2cが配置されるべき位置に配置されている。 To attach the glass unit 2 to the FIX frame 3, first, the setting block 4 and the fixing bracket 90 are attached to each frame member 30. The setting block 4 may be simply placed on the lower frame member 30. In the attached fixing bracket 90, the tip of the indoor extension piece 90e is in contact with the frame finding surface 30g of the frame material 30. In this state, the outdoor side surface of the indoor inner peripheral extending portion 90c of the fixing bracket 90 is arranged at a position where the indoor side surface 2c of the glass unit 2 should be arranged.

次に、枠本体31にセッティングブロック4及び固定金具90が取り付けられた状態で、ガラスユニット2を、下の枠材30に設けられているセッティングブロック4上に載置するとともに各枠材30に設けられているセッティングブロック4の内周側に配置し、屋内側の面2cを固定金具90の屋内内周延出部90cと対向させる。 Next, with the setting block 4 and the fixing bracket 90 attached to the frame body 31, the glass unit 2 is placed on the setting block 4 provided in the lower frame member 30, and is placed on each frame member 30. It is arranged on the inner peripheral side of the provided setting block 4, and the surface 2c on the indoor side faces the indoor inner peripheral extending portion 90c of the fixing bracket 90.

次に、係止金具91の挿入部91aを固定金具90の枠対向部90bと枠見込み面部30aとの間に挿入する。このとき、屋内側の枠凹部30lの屋内側の縁30mと枠見込み面部30aの屋外側の縁とが繋がる部位の外周面が円弧状をなしているので、挿入部91aの先端が枠対向部90bと枠見込み面部30aとの間に案内される。挿入部91aが挿入されて係止片91bが枠対向部90bと接触し、さらに係止金具91を屋内側に押圧することにより係止片91bが外周側に押されて弾性変形しつつ挿入部91aが枠対向部90bと枠見込み面部30aとの間に進入していく。 Next, the insertion portion 91a of the locking metal fitting 91 is inserted between the frame facing portion 90b of the fixing metal fitting 90 and the frame prospective surface portion 30a. At this time, since the outer peripheral surface of the portion where the indoor side edge 30m of the indoor side frame recess 30l and the outdoor side edge of the frame prospective surface portion 30a are connected is formed in an arc shape, the tip of the insertion portion 91a is the frame facing portion. It is guided between 90b and the frame prospective surface portion 30a. The insertion portion 91a is inserted, the locking piece 91b comes into contact with the frame facing portion 90b, and by further pressing the locking metal fitting 91 toward the indoor side, the locking piece 91b is pushed toward the outer peripheral side and elastically deformed while being elastically deformed. 91a enters between the frame facing portion 90b and the frame prospective surface portion 30a.

その後、係止片91bが係止孔90dの外周側に至ると、押し曲げられていた係止片91bが弾性により復帰して係止孔90dに係止される。このとき図10に示すように、係止金具91が固定金具90に係止された状態で、固定金具90の屋内内周延出部90cがガラスユニット2の屋内側の面2cと対面し、係止金具91に設けられた緩衝材11がガラスユニット2の屋外側の面2dに当接して、ガラスユニット2が保持される。このとき、ガラス収容部3aにおいて見込方向における耐熱強化ガラス21と屋内側のLow−Eガラス22との間の位置にて、係止金具91の係止片91bが固定金具90の係止孔90dに係止されている。ここで、係止片91bが係止孔90dに係止されている位置が、係止金具91が固定金具90に係止されている位置に相当する。 After that, when the locking piece 91b reaches the outer peripheral side of the locking hole 90d, the pushed and bent locking piece 91b is elastically restored and locked in the locking hole 90d. At this time, as shown in FIG. 10, with the locking metal fitting 91 locked to the fixing metal fitting 90, the indoor inner peripheral extending portion 90c of the fixing metal fitting 90 faces the indoor side surface 2c of the glass unit 2 and engages with the glass unit 2. The cushioning material 11 provided on the stopper 91 comes into contact with the surface 2d on the outdoor side of the glass unit 2 to hold the glass unit 2. At this time, at the position between the heat-resistant tempered glass 21 in the prospective direction and the Low-E glass 22 on the indoor side in the glass accommodating portion 3a, the locking piece 91b of the locking metal fitting 91 is the locking hole 90d of the fixing metal fitting 90. Is locked in. Here, the position where the locking piece 91b is locked in the locking hole 90d corresponds to the position where the locking metal fitting 91 is locked in the fixing metal fitting 90.

本実施形態の建具1によれば、係止金具91の係止片91bが固定金具90の係止孔90dに係止されている位置は、ガラスユニット2が有するガラス板20、21、22のうちの屋外内周延出部91c側(屋外側)から2枚目に位置するガラス板21、すなわち、真ん中のガラス板21よりも屋内内周延出部90c側(屋内側)に位置しているので、真ん中のガラス板21よりも屋外内周延出部91c側(屋外側)に位置している場合よりも、ガラスユニット2の重心側に配置される。このため、例え、FIX枠3の最も屋外内周延出部91c側(屋外側)のガラス板20と対向する部位が溶融したとしても、ガラスユニット2が脱落しにくい建具1を提供することが可能である。 According to the fitting 1 of the present embodiment, the position where the locking piece 91b of the locking metal fitting 91 is locked in the locking hole 90d of the fixing metal fitting 90 is the position of the glass plates 20, 21, 22 of the glass unit 2. Since it is located on the second glass plate 21 from the outdoor inner peripheral extension 91c side (outdoor side), that is, on the indoor inner peripheral extension 90c side (indoor side) than the middle glass plate 21. , It is arranged closer to the center of gravity of the glass unit 2 than when it is located on the outdoor inner peripheral extension 91c side (outdoor side) of the center glass plate 21. Therefore, even if the portion of the FIX frame 3 facing the glass plate 20 on the most outdoor inner peripheral extending portion 91c side (outdoor side) melts, it is possible to provide the fitting 1 in which the glass unit 2 does not easily fall off. Is.

また、真ん中のガラス板21は、火炎に晒されても割れにくい耐熱強化ガラスなので、屋外内周延出部91c側(屋外側)から2枚目の位置から屋内側は残存する。このため、より長時間にわたって火炎が屋内側に貫通することを防止することが可能である。 Further, since the glass plate 21 in the middle is a heat-resistant tempered glass that is hard to break even when exposed to a flame, the indoor side remains from the position of the second sheet from the outdoor inner peripheral extending portion 91c side (outdoor side). Therefore, it is possible to prevent the flame from penetrating the indoor side for a longer period of time.

また、FIX枠3のガラス収容部3aの外周側に枠中空部30hを有しているので、FIX枠3が高い剛性と断熱性とを備えており、枠中空部30h内には金属製の補強部材8が設けられているので、FIX枠3が溶融する場合であってもガラスユニット2を金属製の補強部材8を介して躯体6上に支持することが可能である。また、補強部材8の見込み面補強部8aから延出された延出補強部8bが、係止金具91が固定金具に係止されている位置よりも屋内側に配置されているので、係止金具91が固定金具90に係止されている位置と躯体6との間が火炎により加熱されにくい。このため、より確実にガラスユニット2を躯体6上に残存させることが可能である。 Further, since the frame hollow portion 30h is provided on the outer peripheral side of the glass accommodating portion 3a of the FIX frame 3, the FIX frame 3 has high rigidity and heat insulating properties, and the inside of the frame hollow portion 30h is made of metal. Since the reinforcing member 8 is provided, the glass unit 2 can be supported on the skeleton 6 via the metal reinforcing member 8 even when the FIX frame 3 is melted. Further, since the extension reinforcing portion 8b extending from the prospective surface reinforcing portion 8a of the reinforcing member 8 is arranged indoors from the position where the locking metal fitting 91 is locked to the fixing metal fitting, it is locked. It is difficult for the metal fitting 91 to be heated by the flame between the position where the metal fitting 91 is locked to the fixing metal fitting 90 and the skeleton 6. Therefore, the glass unit 2 can be more reliably left on the skeleton 6.

また、上及び縦の枠材30のように、躯体固定部30eと共にビス33により躯体6に固定されている補強金具5に、補強部材8の延出片8dが、延出補強部8bより屋外内周延出部91c側(屋外側)で固定されている場合には、延出片8dは屋外内周延出部91c側(屋外側)からの火炎により溶融され難いので、屋外側からの火炎により補強部材8が脱落することを防止し、より長時間にわたってガラスユニット2を躯体6上に残存させることが可能である。 Further, like the upper and vertical frame members 30, the extension piece 8d of the reinforcing member 8 is attached to the reinforcing metal fitting 5 fixed to the skeleton 6 by the screw 33 together with the skeleton fixing portion 30e, and the extending piece 8d of the reinforcing member 8 is outdoors from the extending reinforcing portion 8b. When fixed on the inner peripheral extension 91c side (outdoor side), the extension piece 8d is difficult to be melted by the flame from the outdoor inner peripheral extension 91c side (outdoor side), so that the flame from the outdoor side causes it to melt. It is possible to prevent the reinforcing member 8 from falling off and leave the glass unit 2 on the skeleton 6 for a longer period of time.

このような建具によれば、枠体をなす縦枠材の中空部に設けられている補強部材と横枠材の中空部に設けられている補強部材とに渡る金属製の連結部材が、耐熱強化ガラスの端面と対向する位置に設けられているので、耐熱強化ガラスの端面に向かう火炎を遮ることが可能である。このため、耐熱強化ガラスの端は加熱され難くなるので、少なくとも耐熱強化ガラスが脱落することを抑制することが可能である。従って、耐熱強化ガラスが残存することにより、第一対面部側への火炎の貫通が抑制されるので、より防火性に優れた建具を提供することが可能である。
The fitting is characterized in that the connecting member is provided at a position facing the end face of the heat-resistant tempered glass.
According to such fittings, the metal connecting member extending between the reinforcing member provided in the hollow portion of the vertical frame member forming the frame and the reinforcing member provided in the hollow portion of the horizontal frame member is heat resistant. Since it is provided at a position facing the end face of the tempered glass, it is possible to block the flame toward the end face of the heat-resistant tempered glass. Therefore, since the edge of the heat-resistant tempered glass is less likely to be heated, it is possible to at least prevent the heat-resistant tempered glass from falling off. Therefore, since the heat-resistant tempered glass remains, the penetration of the flame to the first facing surface side is suppressed, so that it is possible to provide a fitting having more excellent fire resistance.
