FIREPROOF WOODEN STRUCTURAL MATERIAL AND FIREPROOF WOODEN MEMBER
To provide a fireproof wooden structural material which exhibits fire spread stopping performance, is excellent in fire resistance, and is easy to manufacture.SOLUTION: A fireproof wooden structural material 1 of the present invention is a fireproof wooden structural material having a quadrangular cross section and including a load support part 11 and a burning margin layer 12 disposed around the load support part. A pair of side burning margin layers 12b and 12d positioned on both sides of the load support part 11 in one direction Y of a cross section of the fireproof wooden structural material are formed of a side part lamina laminate 13 having a direction X orthogonal to the one direction Y as a lamination direction of a lamina. The side lamina laminate 13 has a laminated structure of a lamina in which a plurality of laminae 2 are laminated and bonded so that at least a part 13s present at the same position as the load support part 11 in the lamination direction X of a lamina does not have a laminated surface of woody surface 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こと。【解決手段】本発明の耐火木製構造材１は、荷重支持部１１と、該荷重支持部の周囲に配された燃えしろ層１２とを有する断面四角形状の耐火木製構造材であり、耐火木製構造材の横断面の一方向Ｙにおいて荷重支持部１１を挟んでその両側に位置する一対の側部燃えしろ層１２ｂ，１２ｄが、それぞれ、前記一方向Ｙと直交する方向Ｘをラミナの積層方向とする側部ラミナ積層体１３から形成されており、側部ラミナ積層体１３は、少なくとも、ラミナの積層方向Ｘにおける荷重支持部１１と同位置に存在する部分１３ｓが、木表どうしの積層面を有しないように複数本のラミナ２が積層接着されたラミナの積層構造を有している。【選択図】図１
