[Effect of this embodiment]
(1) In the above embodiment, the sliding window 1 includes a window frame 2 and a shoji screen 3 (4) arranged in the window frame 2, and the window frame 2 includes an upper frame 21, a lower frame 22, and left and right. The shoji 3 (4) is composed of the vertical frames 23 and 24 of the above, and the shoji 3 (4) is a frame formed by the upper stile 31 (41), the lower stile 32 (42) and the left and right vertical stiles 33, 34 (43, 44). The face members 35 (45) are arranged inward, and the left and right vertical frames 33, 34 (43, 44) are formed with hollow portions 335,345 (435,445) penetrating from the upper end to the lower end. The upper and lower ends of the hollow portions 335,345 (435,445) are composed of a profile, and the indoor thermal expansion fireproof materials 10B and 11B and the outdoor thermal expansion fireproof material 10A in the prospective direction of the sliding window 1 are provided. , 11A are arranged facing each other.
Since it has the above configuration, the indoor thermal expansion fireproof materials 10B and 11B and the outdoor thermal expansion fireproof materials 10A and 11A that have reached the thermal expansion temperature at the time of fire expand thermally and approach each other in the prospective direction of the sliding window 1. Therefore, for example, only one of the indoor thermal expansion fireproof materials 10B and 11B and the outdoor thermal expansion fireproof materials 10A and 11A is provided, and the thermal expansion fireproof material of this one is thermally expanded to form a frame material or a frame material. The hollow portion 335,345 (435,445) can be closed more quickly than in the case of closing the hollow portion. Therefore, even if the flammable member is arranged in the hollow portion 335,345 (435,445), it is possible to reduce the possibility that the flammable member is ignited due to the air flow generated by the chimney effect.
(2) A biscap 353, which is a flammable member, is attached to the upper end and the lower end of the vertical frame 34, and the indoor side thermal expansion refractory material 11B and the outdoor side thermal expansion refractory material 11A are expected to be the sliding window 1. It is arranged with the screw cap 353 sandwiched in the direction.
According to such a configuration, the biscap 353 can be covered from the hollow portion 345 side by thermally expanding the indoor thermal expansion refractory material 11B and the outdoor thermal expansion refractory material 11A and approaching each other in the event of a fire. The risk of ignition of the screw cap 353 in the hollow portion 345 can be further reduced.
(3) The reinforcing material 36 (46) for reinforcing the vertical frame 34 (44) is arranged in the hollow portion 345 (445), and the indoor thermal expansion refractory material 11B is attached to the reinforcing material 36 (46).
Therefore, as compared with the case where the indoor thermal expansion refractory material 11B is directly attached to the inner surface of the vertical frame 33 (34), the reinforcing material 36 (46) to which the indoor thermal expansion refractory material 11B is attached is attached to the hollow portion 345 (445). The indoor side thermal expansion refractory material 11B can be easily arranged in the hollow portion 345 (445) by inserting it into the hollow portion 345 (445).
(4) The reinforcing material 36 includes a reinforcing finding piece portion 363 to which the indoor thermal expansion refractory material 11B is attached, and a pair of possible reinforcing finding piece portions 361 and 362 continuous on both side edges of the reinforcing finding piece portion 363. However, the vertical frame 34 has an outdoor finding piece portion 341 (founding piece portion) to which the outdoor thermal expansion refractory material 11A is attached, and a hollow portion 345 is formed by the reinforcing material 36 and the outdoor finding piece portion 341. ..
For this reason, the reinforcing member 36 and the outdoor finding piece portion 341 of the vertical stile 34 are hollow in the vertical stile 34 at locations corresponding to the positions of the groove forming member 38, the guide member 39, the screw cap 353, and the like. A portion 345 can be formed, and the hollow portion 345 can be efficiently closed by the indoor thermal expansion refractory material 11B and the outdoor thermal expansion refractory material 11A attached to the reinforcing finding piece portion 363 and the outdoor finding piece portion 341.
(5) The internal sash 3 is arranged in the window frame 2 so as to be slidable in the left-right direction, and one of the left and right vertical stiles 33 and 34 is the inner sill 34 made of the above-mentioned composite profile. A crescent lock 15 is screwed to one of the pair of prospective reinforcement pieces 361 and 362, which is a combination stile (combination stile).
Therefore, the crescent lock 15 can be fixed by using the reinforcing material 36 to which the indoor thermal expansion refractory material 11B is attached. This eliminates the need for a back plate or the like for fixing the crescent lock 15, so that the assembly of the sliding window 1 can be simplified and the manufacturing cost can be reduced.
