To provide a fireproof sash whose window frame strength can be improved and also which has fire resistance.SOLUTION: A fireproof sash includes a window frame, an outer sliding sash body, and an inner sliding sash body. The sash frame is configured by framing vertical frames and horizontal frames. The sash is made up of the outer sliding sash body and the inner sliding sash body that move along a guide frame constituted by either the vertical frame or the horizontal frame. A newly installed upper frame 21 as the guide frame has a hollow section 214A that extends in the longitudinal direction, and a plurality of holes 219 that communicate with the hollow section 212A are formed along the longitudinal direction in a first lower surface section 214A, which is an inner surface facing the sliding sash body. At least one of the two holes 219 arranged so as to sandwich the mating position of the outer sliding sash body and the inner sliding sash body is closed with a fire-retardant closing member 26.SELECTED DRAWING: Figure 4
【課題】窓枠の強度を向上でき、かつ、防火性を有する防火サッシを提供すること。【解決手段】防火サッシは、窓枠と、外障子、内障子とを備える。窓枠は、縦枠および横枠を枠組みして構成する。障子は、縦枠または横枠の一方で構成されるガイド枠に沿って移動する外障子および内障子で構成する。ガイド枠である新設上枠２１は、長手方向に連続するホロー部２１４Ａを有し、障子に対向する内面である第１下面部２１２Ａには、ホロー部２１４Ａに連通する穴２１９が長手方向に沿って複数形成される。外障子および内障子の召合せ位置を挟んで配置された２つの穴２１９の少なくとも一方は、難燃性の塞ぎ材２６で塞がれている。【選択図】図４
