OPENING/CLOSING WINDOW
PROBLEM TO BE SOLVED: To provide an opening/closing window which efficiently closes a clearance between a sash stile and a frame body with a thermally-expandable material provided between the sash stile and the frame body in case of fire.SOLUTION: An opening/closing window comprises a sash 3 and a frame body. A piece 241c facing an indoor-side surface or an outdoor-side surface of a sash stile facing the frame body when closed is provided on an indoor side or an outdoor side of the frame body. A projecting piece 345 projecting toward an inner peripheral surface of the frame body facing an outer peripheral surface of the sash stile when closed is provided on the outer peripheral surface of the sash stile. A space S3 between the outer peripheral surface of the sash stile and the inner peripheral surface of the frame body is partitioned with the piece 241c of the frame body and the projecting piece 345 of the sash stile, and a thermally-expandable fire-resistive material 56 is arranged within a section.SELECTED DRAWING: Figure 7
【課題】火災時に、障子框と枠体との間に設けた熱膨張材により障子框と枠体との間を効率的に閉塞する開閉窓を提供する。【解決手段】障子３と、枠体とを備え、枠体の室内側若しくは室外側に、閉鎖時に対向する障子框の室内側面若しくは室外側面と対向する片２４１ｃが設けられるとともに、障子框の外周面に、閉鎖時に対向する枠体の内周面に向けて突出する突出片３４５が設けられ、障子框の外周面と枠体の内周面との間の空間Ｓ３を枠体の片２４１ｃ及び障子框の突出片３４５とにより区画すると共に、区画内に熱膨張耐火材５６を配置している。【選択図】図７
