LIGNEOUS FIREPROOF MEMBER
PROBLEM TO BE SOLVED: To provide a ligneous fireproof member in which a texture possessed by wood is provided in an outer casing part and which can prevent an influence due to combustion of a combustion margin part from affecting the main structural part bearing the external load.SOLUTION: In a ligneous fireproof member 1, a fireproof material layer 3 formed of a foamable fireproof covering material, an air layer 4, and a combustion margin wood layer 5 made of wood are laminated in this order toward the outside around a woody load supporting part 2 arranged at the center, and the air layer 4 is sealed between the fireproof material layer 3 and the combustion margin wood layer 5.SELECTED DRAWING: Figure 1
【課題】木材が持つ質感を外被部に備え、かつ、燃え代部の燃焼による影響が外荷重を負担する主要構造部分に及ぶこと防止することを可能とした木質耐火部材を提案する。【解決手段】中央に配設された木質荷重支持部２の周囲に、発泡性耐火被覆材で形成された耐火材層３と、空気層４と、木材からなる燃え代木材層５とが外側に向って順に積層されている木質耐火部材１であって、空気層４は、耐火材層３と燃え代木材層５との間に密閉されている。【選択図】図１
