<p>PROBLEM TO BE SOLVED: To provide a fire-resistant partition wall capable of providing predetermined fire-resistant performance, by restraining a temperature rise in a surface of a wall surface on the opposite side of the fire occurrence side, while restraining the expansion of a wall thickness.SOLUTION: In a fire-resistant partition wall 1, respective both surfaces of a metallic backing 3 are covered with at least a covering material lower lining 5 and a covering material upper lining 7. The metallic backing includes an upper runner 11, a lower runner 13 and a plurality of studs 15. The plurality of studs extend in the vertical direction so as to crosslink the upper runner and the lower runner, and are mutually juxtaposed at an interval. On respective surfaces of both surfaces of the metallic backing, a plurality of pieces of belt-like metallic foil 31 are provided between the covering material lower lining and the covering material upper lining. The belt-like metallic foil is provided with every part opposed to the studs, on an opposite side surface of the metallic backing in the covering material lower lining.</p> |
