PROBLEM TO BE SOLVED: To provide a fireproof ceiling structure such that a fireproof coating of a beam hardly has a defect.SOLUTION: A fireproof ceiling structure comprises an entrance porch wall 12, a steel beam 2, and a ceiling plate (eaves soffit plate) 3, and the steel beam 2 is coated with a fireproof material 4. The entrance porch wall 12 comprises a frame 12a. A fitting structure part 5 for fitting the ceiling plate 3 is supported by an upper surface side (an upper end face part of the entrance porch wall 12) of an upper frame part of the frame 12a. The fitting structure part 5 consists of a ceiling substrate material 51 where the ceiling plate 3 is fixed, a ceiling substrate fixing material 52 coupled to the ceiling substrate material 51 and fixing the ceiling substrate material 51 to the upper end face part of the entrance porch wall 12, and a ceiling parting receiving member 53 located on an upper surface of an outer wall surface material 12d of the entrance porch wall 12 and fixed to the ceiling substrate material 51.SELECTED DRAWING: Figure 1
【課題】梁の耐火被覆に欠損が生じ難い耐火天井構造を提供する。【解決手段】耐火天井構造は、玄関ポーチ壁１２と鉄骨梁２と天井板（軒天板）３とを備えており、上記鉄骨梁２が耐火材４によって被覆されている。上記玄関ポーチ壁１２は、フレーム１２ａを備えている。上記天井板３を取り付けるための取付構造部５は、上記フレーム１２ａにおける上フレーム部の上面側（玄関ポーチ壁１２の上端面部）で支持されている。この取付構造部５は、上記天井板３が固定される天井下地材５１と、この天井下地材５１に連結され、当該天井下地材５１を上記玄関ポーチ壁１２の上記上端面部に固定する天井下地固定材５２と、上記玄関ポーチ壁１２の外壁面材１２ｄの上面上に位置し、上記天井下地材５１に固定される天井見切受け部材５３と、からなる。【選択図】図１
