To provide fixtures for a fireproof cover sheet, a fixing structure therewith for the fireproof cover sheet, and a fireproof structure allowing the fireproof cover sheet for covering a steel beam placed on a connection section of an outer wall material and a floor plate in an orthogonal state to be simply overlapped and fixed on a rear surface of outer wall material without requiring any troublesome process and any electric power tool at site.SOLUTION: A fixture 4(4A) comprises a metal plate with spring elasticity, being configured to form a general consecutive U-shape in a side view with a lower surface part 41, a rear surface part 42, and an upper surface part 43. A fireproof cover sheet 5 covered over a lip part 35 of a rail member 34 attached on outer wall material 1 is elastically clamped between the lower surface part 41 and the upper surface part 43 of the fixture 4(4A).SELECTED DRAWING: Figure 6 【課題】外壁材と床版とが直交状態で取り合う部位に配置される鉄骨梁を包囲するための耐火被覆シートを、現場での面倒な工程や電動工具等を必要とせずに、外壁材のウラ面に重ねて簡単に留め付けることのできる耐火被覆シートの固定金具と、その固定金具を用いた耐火被覆シートの固定構造および耐火被覆構造を提供する。【解決手段】固定金具４（４Ａ）は、ばね弾性を有する金属板からなり、下面部４１と背面部４２と上面部４３とが側面視略コ字状に連続する形状を有する。外壁材１が取り付けられるレール部材３４のリップ部３５に被せた耐火被覆シート５が、固定金具４（４Ａ）の下面部４１と上面部４３との間に弾性的に挟持される。【選択図】図６
