SYNTHETIC COATING FIREPROOF STRUCTURE OF STEEL COLUMN AND CONSTRUCTION METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a synthetic coating fireproof structure of a steel column that never has a gap formed between an extension part of a fireproof coating material and a wall material even if the wall material deforms convexly toward a heating side, and a construction method therefor.SOLUTION: A synthetic coating fireproof structure 10 of a steel column that makes good use of a wall material 2 as a fireproof coating material for a steel column 1 arranged in proximity to the wall material 2 with respect to an opposition range of the steel column 1, uses a fireproof coating material 3 made of a spray material for other ranges, and has a gap between the wall material 2 and the steel column 1 closed by extending and arranging the fireproof coating material 3 toward the wall material 2 is so configured that a fireproof coating substrate material 4 in a plate-like or mesh-like state which is arranged as a substrate of the fireproof coating material 3 extended and arranged from the steel column 1 toward the wall material 2 to be fixed to the steel column 1 and wall material 2, and the fireproof coating material 3 can follow up deformation of the wall material 2 caused away from the steel column 1.SELECTED DRAWING: Figure 3
【課題】壁材が加熱側に凸に変形しても、耐火被覆材の延長部と壁材との境界部に隙間が生じることがない鉄骨柱の合成被覆耐火構造およびその施工方法を提供する。【解決手段】壁材２に近接して配置される鉄骨柱１の耐火被覆材として、壁材２を、その鉄骨柱１の対向範囲について活用するとともに、その他の範囲について吹付け材からなる耐火被覆材３を用い、かつ、耐火被覆材３を、壁材２に向けて延長配置することで壁材２と鉄骨柱１との間を繋いだ鉄骨柱の合成被覆耐火構造１０において、鉄骨柱１から壁材２に向けて延長配置する耐火被覆材３の下地として配置され、鉄骨柱１と壁材２とに固定される板状または網状の耐火被覆下地材４と耐火被覆材３を、鉄骨柱１から遠ざかる方向への壁材２の変形に追従可能に構成した。【選択図】図３
