FIRE-RESISTANT COLUMN AND FIRE-RESISTANT BEAM
PROBLEM TO BE SOLVED: To provide a fire-resistant column and a fire-resistant beam, which allow a column and a beam that remain non-damaged in terms of fireproofing and fire-resistant performances and consider for a burning allowance part, to be formed efficiently at a low cost, using commercially available structural wooden materials.SOLUTION: For example, a fire-resistant column 10 includes: a structural column member 11 having a rectangular cross-section; a side surface part 12a covering each of one of pairs of side surface parts 11a, 11a that face each other of the structural column member 11, the side surface part having a same width as a width b1 of the side surface parts 11a, 11a; a pair of auxiliary column materials 12 for burning allowance, having a rectangular cross-section; and a fire-resistant covering material 13 fitted to continuously cover the other pair of side surface parts 11b, 11b that face each other of the structural column member 11 and an edge surface part 12b of the auxiliary column material 12 for burning allowance on both sides, the fire-resistant covering material having a function to prevent a damage and thermal deterioration caused by burning, when the covered wooden materials are burned for 45 minutes or more at a time of fire.SELECTED DRAWING: Figure 1
【課題】防耐火性能上の非損傷性を備える、燃えしろ部分を考慮した柱や梁を、一般的に流通している構造用木材を用いて、安価に且つ効率良く形成することのできる耐火柱及び耐火梁を提供する。【解決手段】例えば耐火柱１０は、矩形の断面形状を有する構造柱材１１と、構造柱材１１の対向する一方の一対の側面部１１ａ，１１ａを覆って各々配置された、これらの側面部１１ａ，１１ａの幅ｂ1と同様の幅の側面部１２ａを備え、矩形の断面形状を有する一対の燃えしろ用添え柱材１２と、構造柱材１１の対向する他方の一対の側面部１１ｂ，１１ｂ及び両側の燃えしろ用添え柱材１２の端面部１２ｂを、連続して覆い隠すようにして取り付けられた、覆い隠した部分の木材を火災時に４５分間以上、燃焼により損壊させない機能及び熱劣化させない機能を備える耐火被覆材１３とを含んで構成されている。【選択図】図１
