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
