Description
本発明は、ガラス合わせ面同士が樹脂製の接着剤で固着された合わせガラスを嵌め込んで構成される戸体の技術分野に関するものである。 The present invention relates to a technical field of a door body configured by fitting laminated glass in which glass laminated surfaces are fixed with a resin adhesive.
今日、建造物の出入り口に建て付けられる戸体として、上下横框および左右縦框に形成される凹溝状のガラス嵌合部に、複数枚のガラス板のガラス合わせ面同士を樹脂製の接着剤（この接着剤としては後述する特許文献２に記載の「接着樹脂層」の成分を例示することができる。）で固着した合わせガラスを嵌め込むようにしたものがある。このような戸体において、火災が発生した場合、接着剤が熱により融解して合わせガラスの下端面から流れ落ちてしまい、この流れ落ちた接着剤が引火して非火災発生側で燃えてしまうことがあり、防火性、耐火性が損なわれる、という問題がある。
そこで、合わせガラスの下端面と左右両端面の下端部とに耐火性の封止材で被覆して融解した接着剤が該被覆した部位から流れ落ちないようにしたものが知られている（例えば特許文献１参照。）。
Today, as a door to be built at the doorway of a building, glass-bonded surfaces of a plurality of glass plates are bonded to each other on a concave groove-shaped glass fitting part formed on top and bottom sides and left and right sides. There is one in which laminated glass fixed with an agent (a component of “adhesive resin layer” described in Patent Document 2 described later can be exemplified as this adhesive) is fitted. In such a door, when a fire occurs, the adhesive melts by heat and flows down from the lower end surface of the laminated glass, and the flowed adhesive ignites and burns on the non-fire occurrence side. There is a problem that fire resistance and fire resistance are impaired.
Therefore, it is known that the adhesive melted by coating with a fireproof sealing material on the lower end surface of the laminated glass and the lower end portions of the left and right end surfaces is prevented from flowing down from the coated portion (for example, patents). Reference 1).
ところがこのものは、合わせガラスの左右両端面の封止材で被覆した部位よりも上側部位から融解した接着剤が洩れ出てしまう恐れがあり、このようになった場合、該融解して漏れ出た接着剤が引火して非火災発生側への延焼が危惧されるだけでなく、融解した接着剤の膨張力で、封止材の合わせガラスとの接着部位が剥がれたり接着位置がズレたりし、これにより融解した接着剤が漏れ出てしまうという問題があり、ここに本発明の解決すべき課題がある。尚、このものには、合わせガラスの全周を封止材で塞いだ場合、火災の熱により融解した接着剤の膨張により合わせガラスが爆裂してしまうという問題が提起されており、全周をシート材で被覆して融解した接着剤が漏れ出ないようにすることは憚られる。 However, in this case, there is a risk that the melted adhesive may leak from the upper part of the laminated glass covered with the sealing material on both the left and right end faces. Not only is the adhesive ignited and the spread of fire to the non-fire-occurring side is a concern, but due to the expansion force of the melted adhesive, the adhesion part of the sealing material to the laminated glass peels off and the adhesion position shifts, As a result, there is a problem that the melted adhesive leaks out, and there is a problem to be solved by the present invention. In this case, if the entire circumference of the laminated glass is covered with a sealing material, there is a problem that the laminated glass explodes due to the expansion of the adhesive melted by the heat of the fire. It is imperative that the adhesive coated with the sheet material does not leak.

In addition, although the site | part with which the edge of the upper side reed 2 of the left and right vertical reed 4 is abutted is cut out similarly, illustration is abbreviate | omitted.
Further, on the bottom surface of the glass fitting portion 3a of the lower side ridge 3, a foaming refractory material (which is exemplified above) 11 that foams when receiving heat is provided so as to avoid the setting block 7 portion. It is laid over the entire length. When the foamable refractory material 11 is foamed by receiving heat, the sealing material 6a provided on the lower end surface 5b of the laminated glass 5 is peeled off until the lower end surface of the laminated glass 5 is pressed. Is set to prevent. In addition, if it is possible to avoid the molten adhesive 6 flowing out from the lower end surface 5b of the laminated glass 5 by the foamed foam refractory material 11, the foamable refractory material 11 becomes a sealing means for the laminated glass lower end surface 5b, In this case, the sheet-like sealing material 6a which is a sealing means is not necessarily required. And as a sealing means, what seals that the melted adhesive 6 flows out from the lower end surface of the laminated glass 5 is sufficient, and as in the present embodiment, the sealing material 6a, foaming fire resistance Of course, the material 11 may not be used.
Incidentally, a foamable refractory material 11 can be provided in a gap between the setting block 7 and the glass fitting portion 3a at a portion where the setting block 7 of the glass fitting portion 3a is provided in the lower side ridge 3.
下側横框３のガラス嵌合部３ａよりも下側には、樹脂受け部材１２が設けられるが、該樹脂受け部材１２は、下側横框３のガラス嵌合部３ａの前後方向の幅よりも前後方向幅広に設定された状態、本実施の形態では、下側横框３の前後方向両側板３ｃの内面に固定された状態で上側が開口した凹溝状をし、樹脂受け部材１２の左右両端部１２ｃは、下側横框３を超えて左右方向外方に延出して切欠き部４ｃから左右縦框４内に入り込むようになっており、これにより、樹脂受け部材１２は、左右縦框４のガラス嵌合部４ａの開口した下端縁４ｅの下方に臨むようになっている。そして本実施の形態では、左右縦框４の左右方向外側板４ｄの内面にまで至った状態で融解して落下した接着剤６が流れ落ちないよう封止状に固定されている。
因みに樹脂受け部材１２は、前後方向両端縁１２ｄの全体を下側横框３の前後方向両側板３ｃの内面に封止状に固定され、受け止められた接着材６が流れ落ちないように設定されているものであれば凹溝状にする必要は必ずしもなく平板状のものであってもよい。また樹脂受け部材１２としては、図７に示す第二の実施の形態のように、合わせガラス５の厚みよりも前後方向幅広でかつ左右両端面５ｃよりも左右方向外方に越えた位置まである凹溝形状をしたものとすることができるが、この場合には、樹脂受け部材１２を下側横框３に固定するための固定部材１２ａと、後述するように合わせガラス５の左右方向側縁から流れ出て樹脂受け部材１２に流れ落ちた接着剤６が樹脂受け部材１２の端縁から流れ落ちないよう封止する縦板状の封止部１２ｂとを設ける必要がある。
A resin receiving member 12 is provided below the glass fitting portion 3a of the lower side rib 3. The resin receiving member 12 has a width in the front-rear direction of the glass fitting portion 3a of the lower side rib 3. In the present embodiment, in a state where the width is set wider than the front and rear direction, in the present embodiment, the resin receiving member 12 has a concave groove shape with the upper side opened in a state of being fixed to the inner surfaces of the front and rear direction side plates 3c of the lower side rail 3. The left and right end portions 12c of the left and right ends 12c extend outward in the left-right direction beyond the lower side reed 3 and enter into the left and right vertical reeds 4 from the notch 4c. The glass fitting portion 4a of the left and right vertical rod 4 faces the lower end edge 4e opened. In the present embodiment, the adhesive 6 that has melted and dropped in a state of reaching the inner surface of the left-right outer plate 4d of the left-right vertical rod 4 is fixed in a sealed manner so that it does not flow down.
Incidentally, the resin receiving member 12 is set so that the entire front and rear direction end edges 12d are sealed to the inner surfaces of the front and rear side plates 3c of the lower lateral rib 3 so that the received adhesive 6 does not flow down. If it is, it is not always necessary to form a groove, and it may be a flat plate. Further, as the resin receiving member 12, as in the second embodiment shown in FIG. 7, the resin receiving member 12 has a position that is wider in the front-rear direction than the thickness of the laminated glass 5 and beyond the left and right end faces 5 c outward in the left-right direction. In this case, a fixing member 12a for fixing the resin receiving member 12 to the lower lateral ridge 3, and a lateral edge of the laminated glass 5 as will be described later. It is necessary to provide a vertical plate-shaped sealing portion 12b that seals the adhesive 6 that has flowed out of the resin receiving member 12 from the edge of the resin receiving member 12 so as not to flow down from the edge of the resin receiving member 12.
そして戸体１が火災の熱を受けた場合に、融解した接着剤６は、封止材６ａが合わせガラス５の下端面５ｂを封止する状態になっているため、ガラス板５の左右両端面５ｃから流れ出ることになるが、該流れ出た接着剤６は、左右縦框４のガラス嵌合部４ａ内を通る状態で合わせガラス５の左右両端面５ｃ若しくはガラス嵌合部４ａの底面部１２ｆに沿って流れ落ち、該ガラス嵌合部４ａの開口した下端縁４ｅから下方に位置する樹脂受け部材１２内に流れ落ちるようになっている。 When the door 1 receives heat from the fire, the melted adhesive 6 is in a state in which the sealing material 6 a seals the lower end surface 5 b of the laminated glass 5. The adhesive 6 that has flowed out from the surface 5c passes through the glass fitting portion 4a of the left and right vertical gutters 4, and the left and right end surfaces 5c of the laminated glass 5 or the bottom surface portion 12f of the glass fitting portion 4a. And flows down into the resin receiving member 12 positioned below from the opened lower end edge 4e of the glass fitting portion 4a.
叙述の如く構成された本発明の実施の形態において、戸体１が火災の熱で熱せられた場合に、合わせガラス５のガラス合わせ面同士を固着する接着剤６は熱により融解することになるが、該融解した接着剤６は、合わせガラス５の下端面５ｂが封止材６ａにより封止されているため左右縦框４のガラス嵌合部４ａ内において合わせガラス５の左右両端面５ｃから流れ出ることになるが、該流れ出た接着剤６は、合わせガラス５の左右両端面５ｃに沿って流れ落ち、ガラス嵌合部４ａの開口した下端縁４ｅから流れ落ちて樹脂受け部材１２に受け止められることになる。
しかも合わせガラス５の下端面５ｂは、下側横框３のガラス嵌合部３ａ内において封止材６ａにより被覆されていると共に、該封止材６ａは発泡した発泡性耐火材１１により支持されているため、封止材６ａが剥がれたりする等の不具合発生が防止されることになり、この結果、合わせガラス５の下端面５ｂから融解した接着剤６が流れ落ちることがなく、融解した接着剤６は、合わせガラス５の左右両端面５ｃから流れ出て左右縦框４のガラス嵌合部４ａ内において合わせガラス５の左右両端面５ｃに沿う状態で流れ落ちて該ガラス嵌合部４ａの開口する下端縁４ｅから樹脂受け部材１２に流れ落ちることになり、仮にここで融解した接着剤６が引火したとして、上側に下側横框３のガラス嵌合部３ａがあって炎を塞ぐことになるから、非火災発生側に炎が至って延焼してしまうようなことを有効に回避し、防火性、耐火性に優れたものになる。
この結果、下側横框３のガラス嵌合部３ａは、合わせガラス５の下端面から流れ落ちる接着剤６を下側の樹脂受け部材１２に流れ落とす（スルーする）ための加工を施す必要がない。
In the embodiment of the present invention configured as described above, when the door body 1 is heated by the heat of a fire, the adhesive 6 that fixes the glass joining surfaces of the laminated glass 5 is melted by the heat.
