However, in the conventional example as described above, since the equipment unit Y and the building frame 3 are independent of each other, the impact on the wall panel 1 causes the wall panel 1 to bend, The structure is apt to cause damage to the wall panel 1 and cracks in the sealing material between the wall panels 1 due to the bending, vibration when the human body applies pressure or pressure to the wall panel 1, or a weak tapping sound. Due to this, the structure is remarkably deteriorated in texture, and in order to solve these problems, the strength of the reinforcing material of the wall panel 1, the strength of the joint member between the wall panels 1 and the thickness of the wall panel 1 itself are improved. There was a problem that the strength had to be increased by increasing the size. Also, the strength of the reinforcing material of the wall panel 1 is improved,
When the strength of the joint member between the wall panels 1 is improved and the strength is increased by increasing the thickness of the wall panel 1 itself, the weight is increased on the outer periphery of the floor half portion Y ₁ to increase the strength. As shown in FIG. 52, the floor half 21 is subjected to the load of the wall panel 1 and the ceiling panel 9 and the like.
Reinforcing member 100 formed of a metal material such as stainless steel
There was a problem in that it had to be installed to receive the load.

The present invention is intended to solve the above problems, and it is possible to install a wall panel with high mounting strength without increasing the thickness dimension of the wall panel or increasing the strength of the joint member. It is intended to provide a bathroom wall panel mounting structure that can.
