FIRE-RESISTING WOODEN STRUCTURAL MATERIAL
To provide fire-resisting wooden structural material with excellent fire-resistance and easy production feature which allows fire to be suppressed.SOLUTION: Fire-resisting wooden structural material 1 of the present invention formed in a square bar comprises a load support part 11 and a layer 12 to be allowed to burn which is formed along at least three side surfaces of four surfaces extending along a longitudinal direction. Each of both sides sandwiching the load support part 11 in one direction Y of a cross section comprises a first lamina laminated layer 13 of which a lamina laminating direction is a direction X orthogonal to the one direction Y, and a second lamina laminated layer 14, 14 of which a lamina laminated direction is the direction Y at both ends in the direction X. The layer 12 to be allowed to burn surrounding four surfaces of the load support par 11 is formed with the first lamina laminated layer 13, 13 and the second lamina laminated layer 14, 14. The first lamina laminated layer 13, 13 and the second lamina laminated layer 14, 14 are laminated in a way that each lamina configuring those lamina laminated layers has no surface attaching wooden surfaces to each other.SELECTED DRAWING: Figure 1
【課題】燃えどまり性能を発現し、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。【解決手段】本発明の耐火木製構造材１は、角材であり、荷重支持部１１を有し、長手方向に沿って延びる４つの側面のうちの少なくとも３側面に沿って燃えしろ層１２が形成されている。横断面の一方向Ｙにおける荷重支持部１１を挟む両側それぞれに、一方向Ｙと直交する方向Ｘをラミナの積層方向とする第１ラミナ積層部１３を有し、方向Ｘにおける両端に、一方向Ｙをラミナの積層方向とする第２ラミナ積層部１４，１４を有している。第１ラミナ積層部１３，１３及び第２ラミナ積層部１４，１４により、荷重支持部１１の４方を囲む燃えしろ層１２が形成されている。第１ラミナ積層部１３，１３及び第２ラミナ積層部１４，１４は、それぞれを構成するラミナが、木表どうしの接着面を有しないように積層されている。【選択図】図１
