FIREPROOF WOODEN STRUCTURAL MATERIAL
PROBLEM TO BE SOLVED: To provide a fireproof wooden structural material, which has a burning-proof layer with high burning-proof function and excellent fire resistance performance and is easily manufactured.SOLUTION: A fireproof wooden structural material 1 according to this invention has a wooden load support part 11, which supports a long-term loading, and a wooden burning-proof layer 12, which coats the load support part 11. Timber constituting the burning-proof layer 12 has 20% or higher of late wood ratio and 0.6 mm or more of late wood dimension. The timber constituting the burning-proof layer 12 preferably has higher late wood ratio than that of the timber constituting the load support part 11 and the late wood dimension is longer than that of the timber constituting the load support part 11.SELECTED DRAWING: Figure 5
【課題】燃えどまり層が高い燃えどまり機能を発現し、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、長期荷重を支持する木製の荷重支持部１１と該荷重支持部１１を被覆する木製の燃えどまり層１２とを備え、燃えどまり層１２の構成木材は、晩材率が２０％以上、晩材寸法が０．６ｍｍ以上である。燃えどまり層１２の構成木材は、好ましくは晩材率が荷重支持部１１の構成木材より高く、晩材寸法が荷重支持部１１の構成木材より長い。【選択図】図５
