Description
本発明は、建物開口部に設けられる枠体を有したサッシに関し、特に火災発生時にも枠体が脱落することを防止して防火性能を高くしたサッシに関する。 The present invention relates to a sash having a frame body provided at a building opening, and more particularly to a sash having a high fireproof performance by preventing the frame body from dropping even when a fire occurs.
建物開口部に設けられる枠体を有したサッシにおいて、高い防火性能を求められる場合がある。枠体は、内側に障子を納めてなるものや、上枠に巻回自在な扉体を納める収納部を設けてシャッター付サッシを構成するものなどがある。サッシの枠体はアルミ材からなるため、火災発生時の高温に晒されると、軟化、溶融する。防火性能の高いサッシにあっては、そのような場合であっても枠体の崩壊を防止することが必要となる。 In a sash having a frame provided in a building opening, high fireproof performance may be required. The frame body includes a frame in which a shoji is housed inside, and a frame having a shutter with a storage portion that houses a rollable door body on the upper frame. Since the sash frame is made of aluminum, it will soften and melt when exposed to high temperatures during a fire. In a sash having a high fireproof performance, it is necessary to prevent the frame body from collapsing even in such a case.
このため、従来の防火性能を高くしたサッシは、枠体にアルミ材を用いずに溶融点の高いスチール材を採用したり、あるいはアルミ材の肉厚を厚くして、枠体の崩壊を防止するようにしていた。しかし、このような対策では、防火性能を高くしたサッシが一般的なサッシと材料及び構造の点で大きく相違することとなり、コストが高くなってしまうという問題があった。また、別の手段としては、アルミ材の中空内部にスチール製などの補強材を設けるものも知られている。このようなサッシとしては、例えば特許文献１に挙げるようなものがある。 For this reason, conventional sashes with higher fire prevention performance use steel material with a high melting point instead of aluminum material in the frame body, or thicken the aluminum material to prevent the frame body from collapsing. I was trying to do it. However, such a countermeasure has a problem that a sash having a high fireproof performance is greatly different from a general sash in terms of material and structure, and the cost is increased. As another means, there is also known one in which a reinforcing material such as steel is provided in the hollow inside of an aluminum material. An example of such a sash is disclosed in Patent Document 1.
しかし、単にアルミ材の中空内部に補強材を設けるだけでは、四周に枠組みされた枠体の崩壊を十分に防止することは困難であった。また、枠体を構成する縦枠と下枠は、縦枠の側面が下枠の端面に突き合わされて連結固定されているが、火災発生時には連結部分が変形し、縦枠と下枠の間に隙間を生じる可能性があった。縦枠と下枠の間に隙間を生じると、火炎が隙間から侵入するおそれがあり、防火性能を低下させることとなっていた。 However, it is difficult to sufficiently prevent the frame body that is framed around the four sides from being collapsed simply by providing a reinforcing material in the hollow interior of the aluminum material. In addition, the vertical frame and the lower frame constituting the frame body are connected and fixed with the side surfaces of the vertical frame abutting against the end surface of the lower frame. There was a possibility of creating a gap. If a gap is formed between the vertical frame and the lower frame, there is a possibility that a flame may enter from the gap, and the fire prevention performance is reduced.
本発明は前記課題を鑑みてなされたものであり、火災発生時に高温に晒されても、枠体の崩壊及び隙間の発生を防止することのできる構造の簡単なサッシを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a simple sash having a structure capable of preventing the frame body from collapsing and the occurrence of gaps even when exposed to high temperatures in the event of a fire. To do.
前記課題を解決するため、請求項１の発明に係るサッシは、上枠と下枠及び左右の縦枠を枠組みしてなる枠体を有するサッシにおいて、
前記下枠と縦枠はそれぞれ長手方向に沿う中空部を有し、前記下枠の中空部には下補強材が設けられ、前記縦枠の中空部には縦補強材が設けられ、該縦補強材と前記下補強材が連結され、
前記上枠は扉体を支持すると共に巻き上げて収納自在な収納部を有し、前記縦枠の中空部のうち前記上枠と隣接する領域には、前記上枠を固定する裏板部材が設けられ、該裏板部材と前記縦補強材とが連結され、
前記収納部は、上面となる上側部材と、下面となる下側部材とを有し、前記裏板部材は、前記収納部の上側部材及び下側部材と連続し、
前記収納部の下側部材は前記裏板部材に連結され、前記収納部の上側部材は前記縦枠に連結されることを特徴として構成されている。
In order to solve the above-mentioned problem, the sash according to the invention of claim 1 is a sash having a frame formed by framing an upper frame, a lower frame, and left and right vertical frames.
Each of the lower frame and the vertical frame has a hollow portion along the longitudinal direction, a lower reinforcing material is provided in the hollow portion of the lower frame, and a vertical reinforcing material is provided in the hollow portion of the vertical frame. The reinforcing material and the lower reinforcing material are connected ,
The upper frame supports a door body and has a storage portion that can be rolled up and stored, and a back plate member that fixes the upper frame is provided in a region adjacent to the upper frame in a hollow portion of the vertical frame. The back plate member and the longitudinal reinforcing member are coupled,
The storage unit includes an upper member serving as an upper surface and a lower member serving as a lower surface, and the back plate member is continuous with the upper member and the lower member of the storage unit,
The lower member of the storage unit is connected to the back plate member, and the upper member of the storage unit is connected to the vertical frame .
請求項１に係る発明によれば、枠体の中空部内に三方に渡って補強材が連結されているので、火災発生時に枠体を構成する枠材が軟化しても、補強材によって枠体の崩壊や枠材の変形を抑えることができる。また、縦枠のうち収納部の側部を構成する部分においても、縦枠下部と連続して強度を大きくすることができ、火災発生時に収納部及び上枠の崩壊を防止することができる。 According to the first aspect of the present invention, since the reinforcing material is connected in three directions in the hollow portion of the frame body, even if the frame material constituting the frame body softens in the event of a fire, the frame body is formed by the reinforcing material. Collapse and frame deformation can be suppressed. Moreover, also in the part which comprises the side part of a storage part among vertical frames, intensity | strength can be continuously enlarged with a vertical frame lower part, and collapse of a storage part and an upper frame can be prevented at the time of a fire outbreak.
さらに、請求項３の発明に係るサッシは、前記縦枠には前記扉体の左右端部を上下方向に案内するガイドレール部材が取付けられ、該ガイドレール部材は長手方向に沿う中空部を有すると共に、該中空部内にガイドレール補強材が設けられることを特徴として構成されている。 Further, in the sash according to the invention of claim 3, a guide rail member for guiding the left and right end portions of the door body in the vertical direction is attached to the vertical frame, and the guide rail member has a hollow portion along the longitudinal direction. In addition, a guide rail reinforcing material is provided in the hollow portion.
請求項３に係る発明によれば、ガイドレール部材について強度を大きくすると共に、火災発生時の変形や崩壊を防止することができる。 According to the invention which concerns on Claim 3, while increasing intensity | strength about a guide rail member, the deformation | transformation and collapse at the time of fire outbreak can be prevented.
本発明に係るサッシによれば、枠体の縦辺と下辺に渡る構造体によって縦枠と下枠が支持されることにより、火災発生時に高温に晒されても、枠体の崩壊を防止すると共に、縦枠と下枠の間に隙間が発生することを防止できる。 According to the sash according to the present invention, the vertical frame and the lower frame are supported by the structure extending over the vertical side and the lower side of the frame body, thereby preventing the frame body from collapsing even when exposed to high temperatures in the event of a fire. In addition, it is possible to prevent a gap from being generated between the vertical frame and the lower frame.

The vertical reinforcing member 40 is formed in a substantially U-shaped cross section along the inner surface shape of the hollow portion 12 a and is fixed together with the lower frame 11 and the upper frame 10 from the outer peripheral side of the vertical frame 12.
図３には、下補強材４５の斜視図を示している。この図に示すように、下補強材４５は、長手方向に同断面形状を有してなると共に、両端部にはそれぞれ固定部材４６，４６が固定されている。この固定部材４６によって縦補強材４０との連結がなされる。 FIG. 3 shows a perspective view of the lower reinforcing member 45. As shown in this figure, the lower reinforcing member 45 has the same cross-sectional shape in the longitudinal direction, and fixing members 46 are fixed to both ends, respectively. The fixing member 46 is connected to the vertical reinforcing member 40.
図４には、縦補強材４０の斜視図を示している。縦補強材４０は、縦枠１２のうち上枠１０よりも下部の部分に設けられる。縦枠１２のうち上枠１０に隣接する部分については、縦補強材４０の上方に連結される裏板部材４１が設けられ、縦枠１２の中空部１２ａ内に納められる。 FIG. 4 shows a perspective view of the vertical reinforcing member 40. The vertical reinforcing member 40 is provided in a lower part of the vertical frame 12 than the upper frame 10. A portion of the vertical frame 12 adjacent to the upper frame 10 is provided with a back plate member 41 connected to the upper side of the vertical reinforcing member 40 and is stored in the hollow portion 12 a of the vertical frame 12.
縦補強材４０は、下端部に下枠１１及び下補強材４５と連結される下端固定部４０ａを有し、上端部に上枠１０及び裏板部材４１と連結される上端固定部４０ｂを有している。裏板部材４１は、縦補強材４０よりもやや小さい幅に形成されていて、下端部には縦補強材４０の上端固定部４０ｂに固定される下端固定部４１ａを有している。 The vertical reinforcing member 40 has a lower end fixing portion 40a connected to the lower frame 11 and the lower reinforcing member 45 at the lower end portion, and has an upper end fixing portion 40b connected to the upper frame 10 and the back plate member 41 at the upper end portion. doing. The back plate member 41 is formed to have a slightly smaller width than the vertical reinforcing member 40, and has a lower end fixing portion 41 a fixed to the upper end fixing portion 40 b of the vertical reinforcing member 40 at the lower end portion.
図５には、縦補強材４０及び裏板部材４１を納めた縦枠１２と上枠１０及び下枠１１との分解斜視図を示している。この図に示すように、下補強材４５を中空部１１ｃに納めた下枠１１の端部位置には、下補強材４５に固定された固定部材４６が配置される。下枠１１の端面に対して縦枠１２の内周面が突き当てられると共に、縦枠１２の外周側から縦枠１２と下枠１１とがネジ止め固定される。このとき、縦枠１２内の縦補強材４０の下端固定部４０ａと下補強材４５の固定部材４６とが共締めされることにより、縦補強材４０と下補強材４５とが連結される。 FIG. 5 shows an exploded perspective view of the vertical frame 12, the upper frame 10, and the lower frame 11 in which the vertical reinforcing member 40 and the back plate member 41 are housed. As shown in this figure, a fixing member 46 fixed to the lower reinforcing material 45 is disposed at the end position of the lower frame 11 in which the lower reinforcing material 45 is housed in the hollow portion 11c. The inner peripheral surface of the vertical frame 12 is abutted against the end surface of the lower frame 11, and the vertical frame 12 and the lower frame 11 are fixed by screws from the outer peripheral side of the vertical frame 12. At this time, the vertical reinforcing member 40 and the lower reinforcing member 45 are connected by fastening the lower end fixing portion 40a of the vertical reinforcing member 40 in the vertical frame 12 and the fixing member 46 of the lower reinforcing member 45 together.
図５では一方の縦枠１２のみ示しているが、他方の縦枠１２でも同様に、縦補強材４０と下補強材４５とが連結される。したがって、左右の縦補強材４０，４０と下補強材４５とが、枠体１内で三方に連結されることとなる。縦補強材４０と下補強材４５が三方に連結されているので、補強材の構造体としての強度を大きくすることができる。このため、火災が発生してサッシが高温に晒され、枠体１を構成する各枠材が軟化した場合にも、スチール製の縦補強材４０や下補強材４５は強度を保つことができ、これらが三方に連結されていることで各枠材を支持し、枠体１の崩壊を防止することができる。 Although only one vertical frame 12 is shown in FIG. 5, the vertical reinforcing material 40 and the lower reinforcing material 45 are similarly connected to the other vertical frame 12. Therefore, the left and right vertical reinforcing members 40 and 40 and the lower reinforcing member 45 are connected in three directions within the frame 1. Since the vertical reinforcing member 40 and the lower reinforcing member 45 are connected in three directions, the strength of the reinforcing member as a structure can be increased. For this reason, even when a fire occurs and the sash is exposed to a high temperature and the frame members constituting the frame body 1 are softened, the steel vertical reinforcing member 40 and the lower reinforcing member 45 can maintain strength. Since these are connected in three directions, each frame member can be supported and the frame body 1 can be prevented from collapsing.
上枠１０を構成する下側部材１６は、端面が縦枠１２の内周面に突き当てられる。下側部材１６の端面が突き当てられるのは、縦枠１２内において縦補強材４０と裏板部材４１とが連結される部分であって、縦枠１２の外周側から縦枠１２と縦補強材４０、裏板部材４１及び下側部材１６が、共にネジ止め固定される。また、上枠１０を構成する上側部材１５は、端面が縦枠１２の上端部に突き当てられ、縦枠１２の外周側からネジ止め固定される。 An end surface of the lower member 16 constituting the upper frame 10 is abutted against the inner peripheral surface of the vertical frame 12. The end face of the lower member 16 is abutted in a portion where the vertical reinforcing member 40 and the back plate member 41 are connected in the vertical frame 12, and the vertical frame 12 and the vertical reinforcing member are connected from the outer peripheral side of the vertical frame 12. The material 40, the back plate member 41, and the lower member 16 are fixed together with screws. The upper member 15 constituting the upper frame 10 has an end face abutted against the upper end portion of the vertical frame 12 and is fixed by screws from the outer peripheral side of the vertical frame 12.
このように、上枠１０と隣接する縦枠１２の中空部１２ａ内に、縦補強材４０と連結される裏板部材４１を設けたことで、収納部２が設けられる部分において縦枠１２の強度を大きくすることができる。また、火災発生時にも、縦補強材４０と共に縦枠１２の変形などを抑えることができる。 Thus, by providing the back plate member 41 connected to the vertical reinforcing member 40 in the hollow portion 12a of the vertical frame 12 adjacent to the upper frame 10, the portion of the vertical frame 12 in the portion where the storage portion 2 is provided. The strength can be increased. In addition, deformation of the vertical frame 12 together with the vertical reinforcing member 40 can be suppressed even in the event of a fire.
図２に示すように、ガイドレール部材１３には、案内部１３ａの室外側に長手方向に沿う中空部１３ｂを有している。ガイドレール部材１３の中空部１３ｂには、スチール製のガイドレール補強材４７が納められている。ガイドレール補強材４７は、中空部１３ｂの内面形状に略沿う断面略コ字状に形成されており、中空部１３ｂの室内側からネジ止め固定されている。 As shown in FIG. 2, the guide rail member 13 has a hollow portion 13b along the longitudinal direction on the outdoor side of the guide portion 13a. In the hollow portion 13b of the guide rail member 13, a steel guide rail reinforcing material 47 is accommodated. The guide rail reinforcing material 47 is formed in a substantially U-shaped cross section substantially along the inner surface shape of the hollow portion 13b, and is fixed by screws from the inside of the hollow portion 13b.
このように、ガイドレール部材１３の中空部１３ｂにガイドレール補強材４７を設けたことで、ガイドレール部材１３の強度を大きくすると共に、火災発生時にはガイドレール部材１３の変形などを抑えることができる。 Thus, by providing the guide rail reinforcing material 47 in the hollow portion 13b of the guide rail member 13, the strength of the guide rail member 13 can be increased, and deformation of the guide rail member 13 can be suppressed in the event of a fire. .
