FIRE RESISTANT WOOD STRUCTURAL MATERIAL
PROBLEM TO BE SOLVED: To provide a fire resistant wood structural material superior in fire resistant performance easy to manufacture at smaller cost.SOLUTION: Disclosed fire resistant wood structural material 1 includes: a load support part 11 which is formed in a prismatic shape and supports a load for long time; and a burning-off layer 12 which covers at least three faces of the load support part 11 along an axial direction. The burning-off layer 12 has a non-processed laminar 14 which is not processed, and a flame-resisting agent processed laminar 15 which is a non-processed wood soaked with a flame-resisting agent. The non-processed laminar 14 and the flame-resisting agent processed laminar 15 cover the load support part 11 in a state disposed being laminated in a circumferential direction of the load support part 11.SELECTED DRAWING: Figure 1
【課題】製造コストを抑制し、且つ耐火性能に優れ、製造も容易な耐火木製構造材を提供すること。【解決手段】本発明の耐火木製構造材１は、角柱状に形成され、長期荷重を支持する荷重支持部１１と、該荷重支持部１１の軸方向に沿う少なくとも３面を被覆する燃えどまり層１２とを備え、燃えどまり層１２は、無処理の無処理ラミナ１４と、無処理木材に難燃薬剤を含浸させた難燃薬剤処理ラミナ１５とを有し、無処理ラミナ１４及び難燃薬剤処理ラミナ１５は、荷重支持部１１の周方向に積層配置された状態で荷重支持部１１を被覆している。【選択図】図１
