PROBLEM TO BE SOLVED: To significantly improve workability with respect to a compartmentation wall of dry construction method which is installed in a condition where construction is extremely difficult from one side. SOLUTION: The fireproof structure wall 1 of dry construction method includes a vertical steel stud 10 aligned and arranged along a wall core; and noncombustible board materials 2 and 3 attached to only one side of the steel stud. Each firing temperature of the stud and the board materials is 1000°C or higher, and when the ambient temperature on an optional side of the wall body reaches a high temperature of about 950°C, the board materials on the other side of the wall body are kept up to a temperature 200°C and at 160°C or lower in average. The board materials are fixed to the stud by a noncombustible and heat resisting locking tool 8. The locking tool maintains the cohesion of the board materials and the stud, when the ambient temperature on one side area of the wall body reaches a high temperature of 900°C or higher, and also suppresses the thermal deformation of the stud.
