To provide a wooden fireproof member light and excellent in fireproof performance while preventing it from dropping out or losing its sectional part upon fire.SOLUTION: A wooden fireproof member 1A constituting a building is provided with: a load support part 2A supporting load; a first fireproof coating layer 3A arranged on an outer peripheral surface of the load support part 2A; and a second fireproof coating layer 4A arranged on an outer peripheral surface of the first fireproof coating layer 3A, wherein the first fireproof coating layer 3A is formed of one of spray material, plate material, and filing material having a main component of plaster, mortar, or concrete, and the second fireproof coating layer 4A is formed by fixing fiber adiabatic material with lower conductivity and specific gravity than those of the first fireproof coating layer 3A on the first fireproof coating layer 3A.SELECTED DRAWING: Figure 2
【課題】火災時の脱落や断面欠損を低減しつつ、軽量で、優れた耐火性能を有する、木質耐火部材を提供する。【解決手段】木質耐火部材1Aは、建物を構成する木質耐火部材1Aであって、荷重を負担する荷重支持部2Aと、荷重支持部2Aの外周面に設けられる第1耐火被覆層3Aと、第1耐火被覆層3Aの外周面に設けられる第2耐火被覆層4Aと、を備え、第1耐火被覆層3Aは、石膏、モルタル、またはコンクリートを主成分とする、吹付け材、板材、および充填材のうちのいずれかで形成され、第2耐火被覆層4Aは、第1耐火被覆層3Aに比べて、熱伝導率および比重が小さい繊維系断熱材を、第1耐火被覆層3Aに固定して形成されている。【選択図】図2
