FIREPROOF WOODEN STRUCTURAL MATERIAL
To provide a fireproof wooden structural material exhibiting first burning stop property, being excellent in fireproof property and being easily manufactured.SOLUTION: A fireproof wooden structural material 1 includes a load support portion 11, in which, on four side faces along an axial direction, burning margin layers 12 are formed. The fireproof wooden structural material 1 includes first lamina lamination portions 13 and 13 whose lamina lamination direction is a direction X perpendicular to one direction Y of a cross section of the fireproof wooden structural material 1 at both sides of the load support portion 11 in the one direction Y and second lamina lamination portions 14 and 14 whose lamina lamination direction is the perpendicular direction X at both sides of the load support portion 11 in the perpendicular direction X. In the first and second lamina lamination portions 13 and 14, a lamina 4 is a lamina 40 with a discontinuous annual ring not including an early wood portion 42 continuing across both ends of the lamina 4 in the perpendicular direction X in the cross section of the fireproof wooden structural material 1. The burning margin layers 12 are formed of the first and second lamina lamination portions 13 and 14.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】耐火木製構造材１は、荷重支持部１１を有し、軸方向に沿う４側面に燃えしろ層１２が形成されている。耐火木製構造材１の横断面の一方向Ｙにおける荷重支持部１１の両側に、該一方向Ｙと直交する方向Ｘをラミナ積層方向とする第１ラミナ積層部１３，１３を有し、該直交する方向Ｘにおける荷重支持部１１の両側に、該直交する方向Ｘをラミナ積層方向とする第２ラミナ積層部１４，１４を有している。第１及び第２ラミナ積層部１３，１４は、ラミナ４が、耐火木製構造材１の横断面において、該直交する方向Ｘにおけるラミナ４の両端間に亘って連続する早材部４２を有しない年輪非連続ラミナ４０であり、第１及び第２ラミナ積層部１３，１４により燃えしろ層１２が形成されている。【選択図】図１
