WOODEN MEMBER
To provide wooden members, etc. that can be easily fireproofed inside.SOLUTION: A wooden beam 1 is provided with a wooden burn-stop layer 12 on both sides and underside of a wooden load bearing portion 11, and has a through hole 10 that passes between both sides of the wooden beam 1. A fireproofing treatment portion R is provided at both ends of the through hole 10 in the direction of extension, and the load bearing portion 11 inside the wooden beam 1 is exposed on the inner surface of the through hole 10. The fireproofing treatment portion R consists of an annular filler 15, a fireproofing layer 14, and a thermal foaming material 13 sequentially provided from the inner surface of the through hole 10 inwardly at positions corresponding to the burn-stop layers 12 at both ends of the through hole 10 in the direction of extension.SELECTED DRAWING: Figure 1
【課題】内部の耐火処理を容易に行うことのできる木製部材等を提供する。【解決手段】木梁１は、木製の荷重支持部１１の両側面および下面に木製の燃え止まり層１２を設けたものであり、木梁１の両側面の間を貫通する貫通孔１０を有する。貫通孔１０の延伸方向の両端部には耐火処理部Ｒが設けられ、木梁１の内部の荷重支持部１１が、貫通孔１０の内面に露出する。耐火処理部Ｒは、貫通孔１０の延伸方向の両端部の燃え止まり層１２に対応する位置で、環状の充填材１５、耐火層１４、および熱発泡材１３を貫通孔１０の内面から内側に順次設けたものである。【選択図】図１
