RESIN WINDOW
PROBLEM TO BE SOLVED: To provide a resin window capable of preventing slipping-out of a flame in a fire, by restraining a crack by heat of a double-glazing window.SOLUTION: A resin window 12 is constituted for supporting double-glazing 18 on the inside of a frame body 16 formed of resin upper frame 16a, lower frame 16b and left-right jambs 16c, and the double glazing 18 is supported in its outer peripheral end part with a clearance between an inner surface 24c of a bottom wall part 24a of an opening groove 24 and itself on the inside of the opening groove 24 provided in a frame body 16, and while providing a thermal expansion member 42 expanding when heated on the outer surface 24b side of the bottom wall part 24a of the opening groove 24 in the lower frame 16b, the thermal expansion member is not provided between the inner surface 24c of the bottom wall part 24a of the opening groove 24 and a lower end surface 18b of the double glazing 18.
【課題】複層ガラス窓の熱による割れを抑え、火災時等の火炎抜けを防止することができる樹脂窓を提供する。【解決手段】樹脂窓１２は、樹脂製の上枠１６ａ、下枠１６ｂ及び左右の縦枠１６ｃで形成された枠体１６の内側に複層ガラス１８を支持した構成において、複層ガラス１８は、その外周端部が枠体１６に設けられた開口溝２４の内側で該開口溝２４の底壁部２４ａの内面２４ｃとの間に隙間を有して支持され、下枠１６ｂでは、加熱されると膨張する熱膨張性部材４２を開口溝２４の底壁部２４ａの外面２４ｂ側に設ける一方、開口溝２４の底壁部２４ａの内面２４ｃと複層ガラス１８の下端面１８ｂとの間には熱膨張性部材を設けていない。【選択図】図１
