PROBLEM TO BE SOLVED: To improve fire-resistant performance by laminating a calcium silicate material and a gypsum material in this order respectively at both the sides of a structural frame body thereby forming a frame body for a fireproof wall. SOLUTION: A bolt member 6 is penetrated through a hole in a plate-shaped member 10 and a frame member 3 made of a fiber-mixed calcium silicate board, its tip portion is screwed and fitted to a screw hole of a square standing steel member 1, and a frame member 3 is fixed to the square standing steel member 1. And a bolt member 6 is penetrated through a hole of a plate-shaped member 10, a hole 5 of a cover member 5 surrounding the vicinity of two-layer frame member 2 consisting of strengthened gypsum material and a frame member 2, its tip potion is screwed to a screw hole of a plate-shaped member 10, and the frame member 2 is fixed to the square standing steel member 1 outside the frame member 3. And wall bodies 7 are arranged at both the sides of the square standing steel member 1, a spacer member 8 is arranged in the gap between a wall body 7 and the frame member 3. Moreover, sealing material 9 is filled in a gap between the wall body 7 and a cover material 4 surrounding the vicinity of the frame members 2, 3. In this way, fireproof performance can be improved.
