FIREPROOF CONSTRUCTION

PROBLEM TO BE SOLVED: To provide a fireproof construction capable of sufficiently increasing fire resistance efficiency of a structural member of a building while keeping a material cost and a construction cost of a fire resistive covering material low.SOLUTION: A fireproof construction 1, to which the present invention is applied, is provided for a structural member of a building. The fireproof construction includes a steel material 2 that is provided as a structural member such as a beam material or a column material, and a finishing material 3 that is provided away from the steel material 2. Between the finishing material 3 and the steel material 2, an air space G is formed, without being provided with a fire resistive covering material, in an approaching clearance part 30 formed away from the steel material 2, in a position where the finishing material 3 gets closest to the steel material 2.SELECTED DRAWING: Figure 10 【課題】耐火被覆材の材料コスト及び施工コストを抑制すると同時に、建築物の構造材の耐火性能を十分に向上させることのできる耐火構造を提供する。【解決手段】本発明を適用した耐火構造１は、建築物の構造材に設けられるものであり、梁材又は柱材等の構造材として設けられる鉄骨材２と、鉄骨材２から離間させて設けられる仕上材３とを備える。仕上材３と鉄骨材２との間には、仕上材３が鉄骨材２に最も接近した位置で鉄骨材２から離間させて形成される接近隙間部３０に、耐火被覆材が設けられることなく、空気層Ｇが形成される。【選択図】図１０
