FIREPROOF STRUCTURE OF STEEL COLUMN
To provide a fireproof structure of a steel column improved in workability, without impairing fire resistance.SOLUTION: A fireproof structure 1 of a steel column 2 has the steel column 2 and a fireproof plate 3 arranged with a space in relation to the steel column 2 and covering the steel column 2. The fireproof structure 1 of the steel column 2 has an opening 32 formed to the fireproof plate 3, a wiring box 4 having an opening face on one face and fitted to the fireproof plate 3 with the opening face facing the opening 32 and positioned between the fireproof plate 3 and the steel column 2, and a fireproof covering material 7 covering the wiring box 4 between the fireproof plate 3 and the steel column 2. The fireproof covering material 7 has a pair of side covering materials 71 fitted to a left side plate 42 and a right side plate 43 of the wiring box 4 and extending to the steel column 2, and an upper covering material 72 jointing the upper ends of the pair of side covering materials 71 with each other, and the parts corresponding to a back plate 45 and a bottom plate 44 of the wiring box 4 are opened.SELECTED DRAWING: Figure 3
【課題】耐火性を損なうことなく、施工性を向上することができる鉄骨柱の耐火構造を提供する。【解決手段】鉄骨柱２の耐火構造１は、鉄骨柱２と、鉄骨柱２に対して隙間を空けて配置され、鉄骨柱２を被覆する耐火板３と、を備える鉄骨柱２の耐火構造１である。鉄骨柱２の耐火構造１は、耐火板３に形成された開口部３２と、一面に開口面を有し、当該開口面が開口部３２に対向しかつ耐火板３と鉄骨柱２との間に位置するように耐火板３に取り付けられた配線ボックス４と、耐火板３と鉄骨柱２との間において、配線ボックス４を被覆する耐火被覆材７と、を備える。耐火被覆材７は、配線ボックス４の左側板４２及び右側板４３に取り付けられ鉄骨柱２まで延びる一対の側方被覆材７１と、一対の側方被覆材７１の上端部同士をつなぐ上方被覆材７２とを有すると共に、配線ボックス４の背板４５及び底板４４に対応する部分が開放している。【選択図】図３
