To improve fire-resisting performance of a joint portion in a fire-resisting partition wall, employing a dry construction method, by a simple method.
This fire-resisting partition wall (1) includes a structure in which the plurality of face materials (2 and 3) are laminated on at least one side of a steel stud (10). A strip-shaped and frame-shaped adhesive layer (40) is formed between the top layer face material (3) and the substrate face material (2). The top layer face material is bonded to the substrate face material by means of the adhesive layer. The adhesive layer is formed in the backside outer peripheral marginal zone of the top layer face material, and continues throughout the backside perimeter of the top layer face material. A butt joint or a gapped joint (30) is formed between the top layer face materials adjacent to each other. The adhesive layer inhibits hot air, flowing into a gap (25) between the top layer face material and the substrate face material in case of fire in a room or space on one side, from leaking out into a room or space on the other side from the joint (30) of the top layer face material.
