ところで、ガラスの厚い引違サッシや大型の引違サッシでは、使用される戸車は、大型となり、使用される樹脂量が多くなる。そして、このような引違サッシでは、火災が発生した際に戸車の樹脂部分が溶融して発生する可燃性ガスの量が多くなるため、この可燃性ガスを確実に封止する必要がある。
また、このような引違サッシは、封止された可燃性ガスが、火災の熱によって高温となり、高圧状態となって外部へ噴出すると、火災が拡大してしまうため、可燃性ガスの噴出を防止する必要がある。つまり、可燃性ガスが高圧状態となることを防止する必要ある。
By the way, in the case of a thick glass sash or a large size sash, the used door cart becomes large, and the amount of resin used increases. In such a pulling sash, the amount of combustible gas generated by melting the resin portion of the door roller when a fire occurs increases, so it is necessary to securely seal the combustible gas.
In addition, such a sash may prevent the flammable gas from being blown out because the fire spreads when the sealed flammable gas becomes hot due to the heat of the fire and becomes high pressure and blows to the outside. There is a need to. That is, it is necessary to prevent the combustible gas from becoming a high pressure state.

そこで、本発明は、火災の熱によって戸車の樹脂部分が溶融して発生した可燃性ガスを確実に封止し、封止された可燃性ガスが高圧状態となることを防止できる引違サッシを提供することを目的とする。   Therefore, the present invention provides a sash that can reliably seal the combustible gas generated by melting the resin portion of the door roller by the heat of the fire and prevent the sealed combustible gas from becoming a high pressure state. The purpose is to do.

上記目的を達成するため、本発明に係る引違サッシは、構造物の開口部に設けられる枠体と、該枠体の内部に戸車を介してスライド可能に設けられるサッシ障子と、を備え、該サッシ障子の下框には、前記戸車を収容可能な戸車収容部が形成されていて、前記サッシ障子の召合せ框および縦框の少なくとも一方には、前記戸車収容部と連通する中空部と、該中空部と外部とを連通させる戸車調整孔と、が形成されていて、加熱されると前記戸車調整孔を閉塞するとともに前記戸車収容部と前記中空部との連通状態を維持するように発泡可能な第1加熱発泡材が設けられている。   In order to achieve the above object, a pulling sash according to the present invention includes a frame provided at an opening of a structure, and a sash shoji that is slidably provided inside the frame via a door wheel, On the lower arm of the sash shoji, a door cart accommodating portion capable of accommodating the door cart is formed, and at least one of the sash shoji summon and vertical hoist, a hollow portion communicating with the door cart accommodating portion, A door adjustment hole for communicating the hollow portion with the outside is formed, and when heated, the door adjustment hole is closed, and foaming is performed so as to maintain the communication state between the door housing accommodating portion and the hollow portion. A possible first heating foam is provided.

本発明では、火災の熱によって第1加熱発泡材が発泡すると、戸車調整孔が閉塞され、下框の戸車収容部と召合せ框および縦框の少なくとも一方の中空部とが連通した状態に維持されるため、火災の熱によって戸車の樹脂部分が溶融して発生した可燃性ガスを、戸車調整孔から外部へ漏らすことなく、戸車収容部と中空部の空間の両方に封止することができる。
そして、戸車の樹脂部分が溶融して発生した可燃性ガスを戸車収容部のみに封止する場合と比べて、中空部を可燃性ガスを封止する空間として利用することができるため、多量の可燃性ガスが発生した場合にも確実に封止でき、封止された可燃性ガスが高圧状態となることを防止できる。
In the present invention, when the first heating foam material is foamed by the heat of the fire, the door pulley adjustment hole is closed, and the lower door door housing portion and at least one hollow portion of the summon rod and the vertical rod are maintained in communication with each other. Therefore, the combustible gas generated by melting the resin portion of the door roller by the heat of the fire can be sealed in both the door wheel housing portion and the hollow space without leaking from the door wheel adjustment hole to the outside. .
And compared with the case where the combustible gas generated by melting the resin portion of the door roller is sealed only in the door wheel housing portion, the hollow portion can be used as a space for sealing the combustible gas. Even when combustible gas is generated, it can be reliably sealed, and the sealed combustible gas can be prevented from being in a high pressure state.

また、本発明に係る引違サッシでは、前記中空部には、前記戸車収容部と前記戸車調整孔との間に前記戸車収容部および前記戸車調整孔とそれぞれ離間する壁部が設けられていて、前記第1加熱発泡材は、前記壁部と前記戸車調整孔との間に設けられていることが好ましい。
このような構成とすることにより、第1加熱発泡材が発泡しても、壁部によって第1加熱発泡材が戸車収容部と中空部との連通箇所を閉塞することを確実に防止できる。その結果、下框の戸車収容部と召合せ框および縦框の少なくとも一方の中空部とが連通した状態を確実に維持することができる。
Further, in the pulling sash according to the present invention, the hollow portion is provided with wall portions that are spaced apart from the door carriage housing portion and the door wheel adjustment hole, respectively, between the door wheel housing portion and the door wheel adjustment hole. The first heating foam material is preferably provided between the wall portion and the door wheel adjustment hole.
By setting it as such a structure, even if the 1st heating foam material foams, it can prevent reliably that the 1st heating foam material obstruct | occludes the communication location of a door-car accommodating part and a hollow part with a wall part. As a result, it is possible to reliably maintain a state in which the lower door door housing portion and at least one of the hollow portions of the sump and the vertical rod communicate with each other.

また、本発明に係る引違サッシでは、前記下框には、見付け方向の両端部近傍に前記戸車収容部がそれぞれ配置され、該戸車収容部どうしを連通させる連通部が形成されていて、該連通部には、前記サッシ障子の開閉動作を規制する規制部と、加熱されると該規制部を覆うとともに前記連通部の見付け方向の連通状態を維持するように発泡可能な第2加熱発泡材と、が設けられていることが好ましい。
このような構成とすることにより、規制部の樹脂部分が溶融して可燃性ガスが発生した場合にも、この可燃性ガスを発泡した第2加熱発泡材が封止することができる。
また、第2加熱発泡材は、連通部の見付け方向の連通状態を維持するように発泡することにより、召合せ框および縦框の一方の中空部のみが戸車収容部と連通している場合にも、戸車の樹脂部分が溶融して発生した可燃性ガスを、戸車収容部のみでなく連通部を介して中空部に封止することができる。このため、戸車の樹脂部分が溶融して発生した可燃性ガスを確実に封止し、封止された可燃性ガスが高圧状態となることを防止できる。
Further, in the pulling sash according to the present invention, the lower casing is provided with the door carriage accommodating portions in the vicinity of both end portions in the finding direction, and a communication portion for communicating the door carriage accommodating portions is formed.

Are preferably provided.
By setting it as such a structure, even when the resin part of a control part melt | dissolves and combustible gas generate | occur | produces, the 2nd heating foam material which foamed this combustible gas can be sealed.
Further, when the second heating foam material is foamed so as to maintain the communication state in the direction in which the communication portion is found, when only one hollow portion of the summon basket and the vertical rod is in communication with the door carriage housing portion. Moreover, the combustible gas which generate | occur | produced when the resin part of the door roller melt | dissolved can be sealed by a hollow part not only through a door wheel accommodating part but through a communicating part. For this reason, it is possible to reliably seal the combustible gas generated by melting the resin portion of the door roller and prevent the sealed combustible gas from being in a high pressure state.

本発明によれば、戸車の樹脂部分が溶融して発生した可燃性ガスを確実に封止し、封止された可燃性ガスが高圧状態となることを防止できる。   ADVANTAGE OF THE INVENTION According to this invention, the combustible gas which generate | occur | produced when the resin part of the door cart fuse | melted can be sealed reliably, and it can prevent that the sealed combustible gas becomes a high pressure state.
