PROBLEM TO BE SOLVED: To provide a fireproof covering structure having a finishing material with specific properties and performance in fire disaster, as measures for fireproof covering, achieving easy construction control for securing the fireproof covering performance.SOLUTION: A fireproof covering structure A includes a steel member 2 of which the surface is covered with a fireproof material 3, and a wood member 1 laminated on the surface of the fireproof material 3. The thickness of the wood member is determined by the following equation: x=1/a loge(t/b), wherein x: thickness (mm) of covering required for wood member; t: required fire-resistant time (min); a: constant; and b: constant.SELECTED DRAWING: Figure 1
【課題】仕上げ材の火災時性状・性能を明確にして耐火被覆対策として適用することを可能にし、且つ耐火被覆性能を担保するための施工管理を容易に行えるようにした耐火被覆構造を提供する。【解決手段】 鋼製部材２の表面を耐火被覆材３で被覆し、耐火被覆材３の表面に木質材１を積層してなる耐火被覆構造Ａであって、木質材の厚さをｘ＝１／ａ・ｌｏｇｅ（ｔ／ｂ）によって設定する。なお、ｘ：木質材の必要被覆厚さ（ｍｍ）、ｔ：要求耐火時間（分）、ａ：定数、ｂ：定数である。【選択図】図１
