Description

本発明は、防火性に優れた建具に関する。   The present invention relates to a joinery excellent in fire resistance.

内倒し窓のように、障子が室内側又は室外側に開く窓では、枠と障子の間にアーム等が介在するため、枠と障子の間の隙間が大きくなっている。そのため、火災時にはその隙間を火炎や煙等が貫通し、延焼に繋がるおそれがある。
特許文献１には、戸の外周に熱に反応して発泡する発泡材を設けておき、火災時にその発泡材が発泡して枠と戸の間を塞ぐことで、火炎や煙等が侵入するのを防ぐことが開示されている。しかし、前述の内倒し窓等のように、枠と障子の隙間が大きい場合には、発泡材が発泡する途中で室外側や室内側に曲がったり、脱落したりするため、枠と障子の間の隙間をきっちりと塞ぐことが困難であった。 In a window where a shoji opens indoors or outdoors like an inward-facing window, an arm or the like is interposed between the frame and the shoji, so the gap between the frame and the shoji is large. Therefore, at the time of a fire, a flame, smoke, etc. may penetrate the gap and may lead to fire spread.
In Patent Document 1, a foam material that responds to heat and foams is provided on the outer periphery of the door, and the foam material foams and closes between the frame and the door at the time of a fire, so that flame, smoke, or the like enters. Is disclosed. However, if the gap between the frame and the shoji is large, as in the case of the above-mentioned inside-down windows, the foam will bend or fall off to the outside of the room or inside the foam while it is foaming. It was difficult to close the gap tightly.

特開平８−３０３１３３号公報JP-A-8-303133

本発明は以上に述べた実情に鑑み、枠と障子との間の隙間が大きい場合でも、火災時にその隙間を確実に塞ぐことのできる建具の提供を目的とする。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a joinery that can reliably close the gap during a fire even when the gap between the frame and the shoji is large.

上記の課題を達成するために請求項１記載の発明による建具は、枠と、枠に開閉自在に設けた障子とを備え、枠の内周側見込み面又は障子の外周側見込み面に、火災の熱で発泡する耐火材を設けてあると共に、耐火材の見込み方向に隣接する位置に、内周側又は外周側に向けて突出する突壁を有することを特徴とする。   In order to achieve the above object, a joinery according to the first aspect of the present invention includes a frame and a shoji that can be freely opened and closed on the frame, and fires on the inner peripheral side prospective surface of the frame or the outer peripheral side prospective surface of the shoji. And a protruding wall protruding toward the inner peripheral side or the outer peripheral side at a position adjacent to the expected direction of the refractory material.

請求項１記載の発明による建具は、枠の内周側見込み面又は障子の外周側見込み面に、火災の熱で発泡する耐火材を設けてあると共に、耐火材の見込み方向に隣接する位置に、内周側又は外周側に向けて突出する突壁を有することで、火災時に耐火材の発泡する方向が突壁により規制されるため、枠と障子との間の隙間が大きい場合でも、その隙間を発泡した耐火材で確実に塞ぐことができる。また、突壁を有することで、耐火材を密に発泡させることができ、発泡した耐火材による耐火層を維持できる。   The joinery according to the invention of claim 1 is provided with a refractory material foamed by the heat of fire on the inner peripheral side prospective surface of the frame or the outer peripheral side prospective surface of the shoji, and at a position adjacent to the prospective direction of the refractory material. , Because it has a protruding wall that protrudes toward the inner or outer peripheral side, the direction of foaming of the refractory material is regulated by the protruding wall in the event of a fire, so even if the gap between the frame and the shoji is large The gap can be reliably closed with a foamed refractory material. Moreover, by having a protruding wall, a refractory material can be foamed densely and the fireproof layer by the foamed refractory material can be maintained.

When heated to 200 ° C or higher, it expands 5 to 40 times in the thickness direction to form a heat insulation layer. To do. It does not disappear in the event of a fire, and no harmful gases are generated. As such a refractory material 3, for example, trade name “Fibrok” manufactured by Sekisui Chemical Co., Ltd. can be used. After the refractory material 3 is inserted into the refractory material holding portion 25, the refractory material holding portion 25 is held by caulking the lip portion 25a on the inner peripheral side of the refractory material holding portion 25 so as not to fall out of the refractory material holding portion 25. As shown in FIG. 1, the refractory material holder 23 to which the refractory material 3 is attached is fixed to the inner peripheral side prospective surface 7 a of the frame 7 with screws 27.

上枠５は、図２に示すように、内周側見込み面５ａの室外側端部に垂下片２８を有し、その室内側に沿うようにして上枠５の内周側面５ａに、火災の熱に反応して発泡・膨張する耐火材２９が取付けてある。この耐火材２９は、リップ溝形の耐火材ホルダー３０に保持されており、耐火材ホルダー３０は上枠５にネジ３１で固定してある。また、上枠５の内周側見込み面５ａには、ステンレス製の補強板３５が耐火材ホルダー３０とネジ３１で共締めして取付けてある。
上框８の外周側見込み面８ａには、ステンレス製の補強板３２がネジ３３で取付けてあり、その室内側の端部に火災の熱に反応して発泡・膨張する耐火材３４が取付けてある。この耐火材３４は、上枠５に設けられたタイト材ホルダー３６に対向して配置されている。さらに、その上枠５のタイト材ホルダー３６の室内側面にも火災の熱に反応して発泡・膨張する耐火材３７が取付けてあり、この耐火材３７はラッチ１４とラッチ受け１５との係合部に対向して配置されている。上框８の中空部内には、ステンレス製の補強材３８が設けてある。 As shown in FIG. 2, the upper frame 5 has a hanging piece 28 at the outdoor side end portion of the inner peripheral side prospective surface 5 a, and fires on the inner peripheral side surface 5 a of the upper frame 5 along the indoor side. A refractory material 29 that foams and expands in response to the heat is attached. The refractory material 29 is held by a lip groove refractory material holder 30, and the refractory material holder 30 is fixed to the upper frame 5 with screws 31. In addition, a stainless steel reinforcing plate 35 is attached to the inner peripheral side prospective surface 5 a of the upper frame 5 by being fastened together with a refractory material holder 30 and a screw 31.
A stainless steel reinforcing plate 32 is attached to the outer peripheral side prospective surface 8a of the upper collar 8 with screws 33, and a refractory material 34 that foams and expands in response to the heat of the fire is attached to the end of the indoor side. is there. The refractory material 34 is disposed to face the tight material holder 36 provided on the upper frame 5. Further, a refractory material 37 that expands and expands in response to the heat of the fire is also attached to the indoor side surface of the tight material holder 36 of the upper frame 5. The refractory material 37 is engaged with the latch 14 and the latch receiver 15. It is arranged to face the part. A stainless steel reinforcing material 38 is provided in the hollow portion of the upper collar 8.

下枠６は、図２に示すように、Ｌ字形に立ち上がるタイト材ホルダー３９を有し、その室外側面に火災の熱に反応して発泡・膨張する耐火材４０を保持した耐火材ホルダー４１がネジ４２で取付けてある。この耐火材４０は、下框９の室外側に外周側に張り出して形成されたフィン４３と対向して配置されている。前記タイト材ホルダー３９の内周側面にも、火災の熱に反応して発泡・膨張する耐火材４４が設けてある。さらに、下枠６の中空部内にも、火災の熱に反応して発泡・膨張する耐火材４５が設けてある。   As shown in FIG. 2, the lower frame 6 has a tight material holder 39 that rises in an L shape, and a refractory material holder 41 that holds a refractory material 40 that expands and expands in response to the heat of the fire on its outdoor side surface. It is attached with a screw 42. The refractory material 40 is disposed opposite to the fins 43 that are formed on the outer side of the lower heel 9 so as to project outward. A refractory material 44 that expands and expands in response to the heat of the fire is also provided on the inner peripheral side surface of the tight material holder 39. Further, a refractory material 45 that expands and expands in response to the heat of the fire is also provided in the hollow portion of the lower frame 6.

障子２の框８，９，１０は、図２に示すように、内周側が開口したパネル保持溝４６を有し、パネル保持溝４６内の室外側の壁に、火災の熱に反応して発泡・膨張する耐火材４７が取付けてある。下框９のパネル保持溝４６内には、セッティングブロック４８が配置されており、このセッティングブロック４８は火災の熱で溶けにくい金属製のものとなっている。   As shown in FIG. 2, the shoji 8, 9, 10 of the shoji 2 has a panel holding groove 46 opened on the inner peripheral side, and reacts to the heat of the fire on the outdoor wall in the panel holding groove 46. A refractory material 47 that expands and expands is attached. A setting block 48 is disposed in the panel holding groove 46 of the lower rod 9, and the setting block 48 is made of metal that is not easily melted by the heat of fire.

図５は、火災時における竪枠７と竪框１０の隙間部の状態を示している。同図に示すように、火災が発生すると竪枠７の内周側見込み面７ａに設けた耐火材３が内周側に向けて発泡・膨張し、竪枠７の内周側見込み面７ａと竪框１０の外周側見込み面１０ａ間の隙間１７が発泡した耐火材３により塞がれる。これにより、竪枠７と竪框１０の隙間１７から火炎や煙等が貫通するのを阻止できる。耐火材３の室外側に隣接して突壁４が設けてあることで、突壁４が耐火材３の発泡する方向を規制するガイドとなり、広い隙間１７であってもその隙間１７を発泡した耐火材３で確実に塞ぐことができる。また、突壁４を有することで、耐火材３を密に発泡させることができ、発泡した耐火材３による耐火層を維持できる。また、突壁４自体が炎や煙等を遮る効果もある。突壁４は、図４に示すように、アーム１６を竪枠７に取付けているアーム取付具５２と干渉する部分が切欠かれているが、アーム取付具５２は障子２側（内周側）に向けて突出するハット型断面になっており、このアーム取付金具５２が発泡した耐火材３の脱落を防ぐので、突壁４が切欠かれた範囲も竪枠７と竪框１０の間の隙間１７が発泡した耐火材３により確実に塞がれる。
耐火材３を両面テープや接着剤等で竪枠７の内周側見込み面７ａに直接取付けた場合には、長時間風雨にさらされるうちに剥がれ落ちたりするおそれがあるが、本実施形態では耐火材３を耐火材ホルダー２３に保持した上で竪枠７にネジ２７で固定したので、耐火材３が剥がれ落ちるおそれがない。 FIG. 5 shows the state of the gap between the eaves frame 7 and the eaves 10 at the time of a fire. As shown in the figure, when a fire occurs, the refractory material 3 provided on the inner peripheral side prospective surface 7a of the eaves frame 7 foams and expands toward the inner peripheral side, and the inner peripheral side expected surface 7a of the eaves frame 7 and The gap 17 between the outer peripheral side prospective surfaces 10a of the flange 10 is closed by the foamed refractory material 3. As a result, it is possible to prevent a flame, smoke, or the like from penetrating through the gap 17 between the gutter frame 7 and the gutter 10. Since the protruding wall 4 is provided adjacent to the outdoor side of the refractory material 3, the protruding wall 4 serves as a guide for regulating the foaming direction of the refractory material 3, and even if it is a wide gap 17, the gap 17 is foamed. It can be reliably closed with the refractory material 3. Moreover, by having the protruding wall 4, the refractory material 3 can be densely foamed, and the refractory layer of the foamed refractory material 3 can be maintained. In addition, the protruding wall 4 itself has an effect of blocking flames and smoke. As shown in FIG. 4, the protruding wall 4 is notched at a portion that interferes with the arm attachment 52 that attaches the arm 16 to the frame 7, but the arm attachment 52 is on the shoji 2 side (inner peripheral side). Since the arm mounting bracket 52 prevents the foamed refractory material 3 from falling off, the area where the projecting wall 4 is notched is also a gap between the collar frame 7 and the collar 10. The refractory material 3 in which 17 is foamed is reliably closed.
When the refractory material 3 is directly attached to the prospective inner surface 7a of the frame 7 with a double-sided tape or an adhesive, there is a risk of peeling off while exposed to wind and rain for a long time. Since the refractory material 3 is held on the refractory material holder 23 and fixed to the frame 7 with the screws 27, there is no possibility that the refractory material 3 peels off.

また火災時には、上枠５の内周側見込み面５ａに取付けた耐火材２９が内周側に向けて、上框８の外周側見込み面８ａに取付けた耐火材３４が外周側に向けてそれぞれ発泡・膨張して、上枠５の内周側見込み面５ａと上框８の外周側見込み面８ａ間の隙間が塞がれる。両耐火材２９，３４は、上枠５の垂下片２８と上框８の立上げ片４９の見込み方向に隣接して配置されているため、先に述べた突壁４と同様に耐火材２９，３４の発泡する方向を規制し、耐火材２９，３４が曲がったり脱落したりするのを防ぐことができる。また、上枠５のタイト材ホルダー３６の室内側面に取付けた耐火材３７が室内側に向けて発泡し、障子２の周囲と上枠５間の隙間を塞ぐ。室外側で火災が起きたときには、障子２は室外側に膨らむように変形し、それに伴って上框８の立上げ片４９が上枠５のタイト材５０から離れようとする。本建具は上記のように耐火材２９，３４，３７が設けてあることで、室外側から室内側への火の侵入がまず耐火材２９により防がれ、耐火材２９を突破され且つタイト材５０が上框８から離れたとしても、耐火材３４により火の侵入を防ぐことができる。耐火材３４は、タイト材５０を保護する働きもある。さらに、耐火材３４が突破され且つ上框８が室内側に変位したとしても、室内側に向けて発泡する耐火材３７により火の侵入が防がれる。以上の作用により、上枠５と上框８の間を火が貫通するのを確実に防ぐことができる。
さらに、下枠６のタイト材ホルダー３９の室外側面に取付けた耐火材４０が室外側に向けて発泡し、発泡した耐火材４０が下框９にパネル保持溝４６内の水を抜くために下框９の長手方向両端部に形成された水抜き孔を塞ぎ、水抜き孔から火炎や煙等が入るのを阻止する。下框９はヒンジ部１２で下枠６と連結されているが、ヒンジ部１２は長手方向の両端部が竪框１０と干渉しないように切欠かれており、また下枠のタイト材５１は長手方向の両端部が竪枠７と干渉しないように切欠かれているので、そのままでは下枠６の両端部における下框９との隙間から火が貫通するおそれがある。本建具では、下枠６のタイト材ホルダー３９の内周側面に取付けた耐火材４４が内周側に向けて発泡し、発泡した耐火材４４が下枠６と下框９間の隙間を塞ぐことで、下枠６の両端部における下框９との隙間から火が貫通するのを防ぐことができる。耐火材４４は、タイト材５１を保護する働きもある。耐火材４０，４４は、下枠６の長手方向の全長に設けてもよいが、下枠６の長手方向の両端部だけに設けてあってもよい。
さらに、下枠６の中空部内に設けた耐火材４５が発泡して下枠６の排水孔を塞ぎ、排水孔から火炎や煙等が入るのを阻止する。また、框８，９，１０のパネル保持溝４６内に設けた耐火材４７が発泡してパネル保持溝４６内の隙間を塞ぐことで、框８，９，１０と複層ガラス１１との間から火炎や煙等が貫通するのを阻止できる。 Further, in the event of a fire, the refractory material 29 attached to the inner peripheral side prospective surface 5a of the upper frame 5 faces the inner peripheral side, and the refractory material 34 attached to the outer peripheral side prospective surface 8a of the upper rod 8 faces the outer peripheral side, respectively. By foaming and expanding, a gap between the estimated inner surface 5a of the upper frame 5 and the estimated outer surface 8a of the upper collar 8 is closed. Since both the refractory materials 29 and 34 are disposed adjacent to the prospective direction of the hanging piece 28 of the upper frame 5 and the rising piece 49 of the upper rod 8, the refractory material 29 is provided in the same manner as the protruding wall 4 described above. , 34 can be regulated in the foaming direction, and the refractory materials 29, 34 can be prevented from bending or falling off. Moreover, the refractory material 37 attached to the indoor side surface of the tight material holder 36 of the upper frame 5 foams toward the indoor side, and closes the gap between the shoji 2 and the upper frame 5. When a fire breaks out on the outdoor side, the shoji 2 is deformed so as to swell outward, and accordingly, the rising piece 49 of the upper rod 8 tends to be separated from the tight material 50 of the upper frame 5. Since the present joinery is provided with the refractory materials 29, 34, and 37 as described above, the intrusion of fire from the outdoor side to the indoor side is first prevented by the refractory material 29, and the refractory material 29 is broken through and the tight material. Even if 50 is separated from the upper rod 8, the fireproof material 34 can prevent the intrusion of fire. The refractory material 34 also functions to protect the tight material 50. Furthermore, even if the refractory material 34 is broken through and the upper rod 8 is displaced to the indoor side, the intrusion of fire is prevented by the refractory material 37 that foams toward the indoor side. With the above action, it is possible to reliably prevent the fire from penetrating between the upper frame 5 and the upper rod 8.
Further, the refractory material 40 attached to the outdoor side surface of the tight material holder 39 of the lower frame 6 is foamed toward the outdoor side, and the foamed refractory material 40 is lowered to drain the water in the panel holding groove 46 to the lower rod 9. The drain holes formed at both ends in the longitudinal direction of the eaves 9 are closed to prevent entry of flames and smoke from the drain holes. The lower collar 9 is connected to the lower frame 6 by a hinge part 12, but the hinge part 12 is notched so that both ends in the longitudinal direction do not interfere with the collar 10, and the tight material 51 of the lower frame is elongated. Since both ends in the direction are cut out so as not to interfere with the frame 7, there is a possibility that fire may penetrate through the gap between the both ends of the lower frame 6 and the lower frame 9. In this joinery, the refractory material 44 attached to the inner peripheral side surface of the tight material holder 39 of the lower frame 6 foams toward the inner peripheral side, and the foamed refractory material 44 closes the gap between the lower frame 6 and the lower rod 9. Thus, it is possible to prevent the fire from penetrating from the gap between the lower frame 6 and the lower rod 9 at both ends. The refractory material 44 also functions to protect the tight material 51. The refractory materials 40 and 44 may be provided over the entire length of the lower frame 6 in the longitudinal direction, but may be provided only at both ends of the lower frame 6 in the longitudinal direction.
Further, the refractory material 45 provided in the hollow portion of the lower frame 6 foams and closes the drain hole of the lower frame 6, thereby preventing flames, smoke, and the like from entering from the drain hole. Further, the refractory material 47 provided in the panel holding groove 46 of the eaves 8, 9, 10 foams and closes the gap in the panel holding groove 46, so that the space between the eaves 8, 9, 10 and the multilayer glass 11 is reduced. Can prevent the penetration of flames and smoke.

以上に述べたように本建具は、火災時に枠１と障子２の隙間、障子２の框８，９，１０と複層ガラス１１との隙間、排水孔等が発泡した耐火材３，２９，３４，３７，４０，４４，４５，４７により塞がれるため、火炎や煙等が室内外を貫通するのを阻止し、延焼を防止することができる。特に、耐火材３の見込み方向に隣接する位置に内周側に向けて突出する突壁４を設けたことで、耐火材３の発泡する方向を突壁４が規制するため、アーム１６が介在する竪枠７と竪框１０間の広い隙間１７であっても、発泡した耐火材３でその隙間１７をきっちり塞ぐことができる。   As described above, this joinery is made of the refractory material 3, 29, foamed in the gap between the frame 1 and the shoji 2, the gap between the shochu 8, 9, 10 and the multi-layer glass 11, the drainage hole, etc. Since it is blocked by 34, 37, 40, 44, 45, 47, it is possible to prevent flames and smoke from penetrating indoors and outdoors and to prevent the spread of fire. In particular, by providing the protruding wall 4 protruding toward the inner peripheral side at a position adjacent to the prospective direction of the refractory material 3, the protruding wall 4 regulates the foaming direction of the refractory material 3, so that the arm 16 is interposed. Even if it is the wide clearance gap 17 between the eaves frame 7 and the eaves 10, the clearance gap 17 can be tightly closed with the foamed refractory material 3.

本発明は以上に述べた実施形態に限定されない。耐火材に隣接して設けられる突壁は、耐火材ホルダーと別体で形成することもできる。耐火材は、障子の外周側見込み面に設けることもでき、その場合には突壁は外周側に向けて突出して設ける。また耐火材は、枠の内周側見込み面又は障子の外周側見込み面に両面テープ等で直接取付けることもできる。突壁は、耐火材の室内側に隣接して設けることもできる。障子の開き方は任意であり、例えば開き窓、すべり出し窓等、あらゆる窓種に適用することができる。   The present invention is not limited to the embodiments described above. The protruding wall provided adjacent to the refractory material can be formed separately from the refractory material holder. A refractory material can also be provided in the outer peripheral side prospective surface of a shoji, and in that case, a protruding wall is provided protruding toward the outer peripheral side. Moreover, a refractory material can also be directly attached to the inner peripheral side prospective surface of a frame or the outer peripheral side prospective surface of a shoji with a double-sided tape or the like. The protruding wall can be provided adjacent to the indoor side of the refractory material. The method of opening the shoji is arbitrary, and can be applied to all types of windows such as an open window and a sliding window.
