PROBLEM TO BE SOLVED: To provide a method for constructing a fireproofing wall having heat insulation preventing columns from burning if a fire occurs in a neighboring house, or the like.SOLUTION: In order to construct a fireproofing wall, a fireproof board 10 is used, in which a periphery 11a of a lath net 11 with wires W assembled in meshes projects from a peripheral end surface 13a of a mortar base material 13. The fireproof boards 10 are constructed by making them adjacent with each other and superposing the peripheries 11a of the lath nets 11 on the other. At first, a fire-resisting insulation backing board 20 is laid along a column 1. Then, the superposed peripheries 11a of the lath nets 11 of the adjacent fireproof boards 10 are laid along the fire-resisting insulation backing board 20. Subsequently, fixing boards 30 are applied to two or more places in one side of the superposed peripheries 11a of the lath nets 11. Then, fixtures 40 with shanks 42 are driven from the fire-resisting insulation backing board 20 up to the column 1. Thereby, the fixing boards 30 are pushed to the lath nets 11 and the fireproof boards 10 are fixed on the column 1. |
