To provide a partition fire proof wall capable of enlarging an effective area in a parking room by reducing a protruding portion from a column and a beam position into the parking room, and largely reducing a gap through which fire and smoke enter adjacent parking room in a fire.SOLUTION: A partition fire proof wall 20 is installed along a steel frame structure 10A positioned in a boundary A-A of a parking room and includes a partition steel frame 12A constituting the steel frame structure 10A, a plurality of support metal fittings 30, a heat proof panel 40 and a fire proof coating 50. The partition steel frames 12A are a partition column 13A, a partition beam 14A and a partition brace. The support metal fitting 30 is fixed to the partition steel frame 12A inside the steel frame structure 10A in plan view along the boundary with an interval. The heat proof panel 40 has no opening, is fixed to the support metal fitting 30 inside the steel frame structure 10A in plan view, and covers an opening portion of the steel frame structure 10A along the boundary A-A. The fire proof coating 50 is continuously formed on an outer face of the partition steel frames 12A, the support metal fitting 30 and the heat proof panel 40.SELECTED DRAWING: Figure 4
【課題】柱及び梁の位置から駐車室内への突出部分を低減して駐車室の有効面積を大きくでき、かつ火災時に火炎や煙が隣接する駐車室に侵入する隙間を大幅に低減できる間仕切耐火壁を提供する。【解決手段】間仕切耐火壁２０が、駐車室の境目Ａ−Ａに位置する鉄骨構造１０Ａに沿って設置され、鉄骨構造１０Ａを構成する間仕切鉄骨１２Ａ、複数の支持金具３０、耐熱パネル４０、及び耐火被覆５０を有する。間仕切鉄骨１２Ａは、間仕切柱１３Ａ、間仕切梁１４Ａ、及び間仕切筋交いである。支持金具３０は、鉄骨構造１０Ａの平面視内側で間仕切鉄骨１２Ａに境目に沿って間隔を隔てて固定されている。耐熱パネル４０は、開口が無く、鉄骨構造１０Ａの平面視内側で支持金具３０に固定され境目Ａ−Ａに沿って鉄骨構造１０Ａの開口部を塞ぐ。耐火被覆５０は、間仕切鉄骨１２Ａ、支持金具３０、及び耐熱パネル４０の外面に連続的に形成されている。【選択図】図４
