FIREPROOF STRUCTURE OF HORIZONTAL LUMBER
To provide a fireproof structure of horizontal lumber in which the horizontal lumber with through holes is arranged so as to face the indoor surface of the outer wall, the fireproof structure having good workability when installing fireproof materials on the horizontal lumber.SOLUTION: A fireproof structure 1 of horizontal lumber 3 includes an outer wall 2 having a through hole 22, a horizontal lumber 3 facing the indoor side surface of the outer wall 2, and a fireproof material 6 covering the horizontal lumber 3. The horizontal lumber 3 has a through hole 33 formed at a position corresponding to the through hole 22. The fireproof material 6 has an indoor surface covering portion 61 that covers a portion of the indoor side surface of the horizontal lumber 3 excluding the through hole 33 and a cylindrical covering portion 62 connecting the indoor surface covering portion 61 and the outer wall 2 in a state where the through hole 22 and the through hole 33 are in communication with each other. In the cylindrical covering portion 62, one end in the central axis direction is a fixed end fixed to the connection target, and the other end in the central axis direction is a non-fixed end that is non-fixed to the connection target.SELECTED DRAWING: Figure 1
【課題】貫通孔が形成された横架材が、外壁の屋内側の面に対向するように配置された構造において、横架材に対して耐火材を施工する際に、施工性がよい横架材の耐火構造を提供する。【解決手段】横架材３の耐火構造１は、貫通孔２２を有する外壁２と、外壁２の屋内側の面に対向する横架材３と、横架材３を被覆する耐火材６と、を備える。横架材３は、貫通孔２２に対応する位置に形成された貫通孔３３を有する。耐火材６は、横架材３の屋内側の面のうち貫通孔３３を除く部分を被覆する屋内面被覆部６１と、貫通孔２２と貫通孔３３とを通じさせた状態で、屋内面被覆部６１と外壁２とをつなぐ筒状被覆部６２と、を有する。筒状被覆部６２は、中心軸方向の一方の端部がその接続対象に対して固定された固定端部であり、中心軸方向の他方の端部がその接続対象に対して非固定である非固定端部である。【選択図】図１
