FRAME BODY AND FITTING
To provide a frame body and a fitting capable of improving fire prevention performance by maintaining screws coming off from screw holes for a predetermined period of time in the event of a fire.SOLUTION: A bottom rail 52 has a hollow portion 525 defined by an outdoor width surface 521, an interior width surface 522, an inner circumferential side depth surface 523 in which a screw hole 526 is formed, and an outer circumferential side depth surface 524. An inner circumferential side depth surface 533 of a vertical stile has an insertion hole 5331 into which an assembly screw 91 screwed into the screw hole 526 is inserted. A reinforcing material 62 placed in the hollow portion 525 of the bottom rail 52 has an inner circumferential depth piece 622 disposed opposite to the inner circumferential side depth surface 523 with the screw hole 526 interposed therebetween in at least a part of the screwing area that is screwed together with the assembly screw 91 of the screw hole 526, and a width piece 621 provided along the outdoor width surface 521. A heating foaming material 86 is provided on the inner circumferential depth piece 622.SELECTED DRAWING: Figure 5
【課題】火災時にビスホールからビスが外れることを所定時間維持できて防火性能を向上できる枠体および建具を提供すること【解決手段】下框５２は、室外見付け面部５２１と、室内見付け面部５２２と、ビスホール５２６が形成された内周側見込み面部５２３と、外周側見込み面部５２４とで区画される中空部５２５を有する。縦框の内周側見込み面部５３３は、ビスホール５２６に螺合される組立ネジ９１が挿通される挿通孔５３３１を有する。下框５２の中空部５２５に配置される補強材６２は、ビスホール５２６の組立ネジ９１と螺合する螺合領域の少なくとも一部において内周側見込み面部５２３に対してビスホール５２６を挟んで対向配置される内周見込み片６２２と、室外見付け面部５２１に沿って設けられる見付け片６２１とを有する。内周見込み片６２２には加熱発泡材８６が設けられる。【選択図】図５
