FIRE-RESISTING STEEL BEAM
PROBLEM TO BE SOLVED: To provide a fire-resisting steel beam that may be installed, readily, is highly fire-resistant, and has an undersurface of a lower flange covered with a thermal expansion fire-resisting material.SOLUTION: A fire-resisting steel beam includes: a steel beam comprising two flanges that face each other in a horizontal direction and a web connecting the flanges; first and second standing members having a side surface parallel to the web and disposed on both sides of the web on a top surface side of a lower flange of the two flanges located in a lower side; a thermal expansion fire-resisting material covering at least from a top edge of the side surface of the first standing member and over an undersurface of the lower flange, and an entire surface of the second standing member to a top edge of the side surface; and a sprayed fire-resisting material covering at least the web and a part between the web and the side surface of the standing member on the top surface side of the lower flange.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耐火材で覆われている耐火鉄骨梁を提供することを課題とする。【解決手段】水平方向に対向する二枚のフランジと、該フランジを連結する一枚のウェブとからなる鉄骨梁と、前記ウェブに平行な側面を有し、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上面側であって前記ウェブの両側にそれぞれ設けられた第一および第二の立上部材と、少なくとも、前記第一の立上部材の側面上端部から前記下側フランジの下面側を通り前記第二の立上部材の側面上端部までの全面を覆う熱膨張性耐火材と、少なくとも、前記ウェブと、前記下側フランジの上面側であって前記ウェブと前記立上部材の側面とに挟まれた部分とを覆う吹付耐火材と、を有することを特徴とする耐火鉄骨梁。【選択図】図１
