PROBLEM TO BE SOLVED: To provide a resin fitting that suppresses deformation of a tip in the lengthwise direction in an out-of-plane direction by making the reinforcing member thermally elongate and warp due to a fire, thereby enhancing the flame-shielding property.SOLUTION: A resin vertical frame member 2a of a frame body 2 of a resin fitting has a sash supporting part 22 and a protrusion 21 in an out-of-plane direction, with an interval in between, and a metallic reinforcing member 4 is inserted and fitted in a first hollow part 28 of the sash supporting part 22 while a metallic supporting member 5 is inserted and fitted in a second hollow part 27 of the protrusion 21. By connecting an end in the lengthwise direction of the reinforcing member 4 and an end in the lengthwise direction of the supporting member 5 with a connecting member 6, deformation at the end in the lengthwise direction of the reinforcing member 4 in the out-of-plane direction is suppressed, when the reinforcing member 4 is heated at a time of fire. Spreading of the fire through a space between the sash and the sash supporting part is also suppressed, thereby enhancing the flame shielding property.
【課題】火災により補強部材が熱伸びして反ることで、補強部材の長さ方向端部が面外方向に変形することを抑制し、遮炎性を向上できるようにした樹脂製建具とする。【解決手段】枠体２の樹脂製縦枠材２ａは、障子支持部２２と突出部２１が面外方向に離隔して有し、障子支持部２２の第１中空部２８に金属製の補強部材４を挿入して取り付け、突出部２１の第２中空部２７に金属製の支持部材５を挿入して取り付ける。補強部材４の長さ方向端部と支持部材５の長さ方向端部を連結部材６で連結することで、補強部材４が火災時に加熱されたときの補強部材４の長さ方向端部の面外方向への変形を抑制し、障子と障子支持部との間を火炎が流れることを抑制して遮炎性を向上する。【選択図】図２
