FIREPROOF STEEL BEAM
PROBLEM TO BE SOLVED: To provide a fireproof steel beam, which can be easily constructed and has high fire-resistant performance and a lower flange undersurface covered with a thermally expandable sheet.SOLUTION: A fireproof steel beam comprises: a steel beam made up of two flanges facing each other in horizontal direction and a piece of web that connects the two flanges; a thermally expandable fireproof material, which continuously covers undersurface, lateral face and at least a part of a top face of the lower flange located lower than the other of the two flanges; a thermally disappearing member, which is located on the thermally expandable fireproof material along both ends of the top face of the lower flange; and a spray fireproof material, which continuously covers at least the web lateral face and the top face of the thermally disappearing member.SELECTED DRAWING: Figure 1
【課題】施工が容易で、耐火性能が高い、下側フランジの下面が熱膨張性シートで覆われている耐火鉄骨梁を提供する。【解決手段】水平方向に対向する二枚のフランジと、前記二枚のフランジを連結する一枚のウェブとからなる鉄骨梁と、前記二枚のフランジのうち、下方に位置する下側フランジの下面と側面と少なくとも上面の一部を連続的に覆う熱膨張性耐火材と、前記下側フランジの上面両側端部に沿って、前記熱膨張性耐火材上に位置する熱消失性部材と、少なくとも、前記ウェブ側面と前記熱消失性部材上面とを連続的に覆う吹付耐火材と、を有する耐火鉄骨梁。【選択図】図１
