PROBLEM TO BE SOLVED: To provide a smokeproof sheet member having no crease and being changeable.SOLUTION: A smokeproof hanging wall panel formed by stretching a smokeproof sheet member 15 on longitudinal and transverse frames of four circumferential sides. Movable frame bodies 13 are connected with both right and left sides of the smokeproof sheet member 15 and are screwed onto the respective longitudinal frames 11. These movable frame bodies 13 are tightened to longitudinal frames 11 on both sides with threads to extend the smokeproof sheet member 15 in the right and left horizontal directions. In the up and down directions, no tensile force is applied. The longitudinal frame 11 has an approximately U-shaped cross section, and a movable frame body 13 has an angular pipe body, and the movable frame body 13 is housed inside the longitudinal frame 11 movably in the lateral direction. The transverse frame 12 also has an approximately U-shaped cross section, and a pushing member 14 comprising a curved pipe body is internally provided and fixed to the transverse frame 12. A sealing material is charged into between the longitudinal and transverse frames 11, 12 and a smokeproof sheet member 15. |
