PROBLEM TO BE SOLVED: To provide a structure of a window device with wind stop board, which can prevent a gap between an undersurface of a door head and an upper end face of a pair of meeting stiles even in fire breaking, and improve fireproof performance.SOLUTION: A locking concave groove 50 extending in indoor-outdoor direction is formed between airtight pieces 46a, 46b whose lower ends are elastically butted against an upper end face of a meeting stile 11c on an undersurface of a wind stop board body 38 forming a wind stop board 13a fixed in a fixing groove 51 of a door head 4a. Heat foaming materials 49 are supported in the locking concave grooves 50 respectively so as to prevent the heat foaming materials from dropping off.SELECTED DRAWING: Figure 5
【課題】火災発生時にも、上枠の下面と１対の召し合わせ框の上端面との間に隙間が生じる事を防止し、防火性能の向上を図れる、風止め板付窓装置の構造を実現する。【解決手段】上枠４ａの固定用溝５１内に固定された風止め板１３ａを構成する風止め板本体３８の下面のうち、それぞれの下端部を召し合わせ框１１ｃの上端面に弾性的に当接させる気密片４６ａ、４６ｂ同士の間部分に、屋内外方向に伸長した係止凹溝５０を形成する。そして、この係止凹溝５０内に、下方への脱落を防止した状態で、加熱発泡材４９をそれぞれ支持する。【選択図】図５
