BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure of a wall panel, and more particularly to a fixing structure of a wall panel to a waterproof pan having a back portion embedded in a concrete slab such as a PC slab.

[0002]

2. Description of the Related Art A PC floor slab is obtained by arranging reinforcing bars in a formwork usually in a lattice shape, casting concrete in the formwork, curing and curing.

In order to install a bathroom on a floor slab constructed using the PC floor slab, a waterproof pan is placed on the floor slab, and a wall panel is erected on the periphery of the waterproof pan. A ceiling panel is erected on it.

In such a conventional method, since the waterproof pan is mounted on the floor slab and then the level is adjusted, the amount of on-site work is increased and it takes time. In addition, it is necessary to provide a level adjustment allowance (space portion) between the waterproof pan and the floor slab, and there is a problem that the stepping height of the waterproof pan is increased accordingly.

[0005] Another conventional example is disclosed in Japanese Patent Application Laid-Open No. 62-12562.
No. 36 describes a PC floor slab having a rising edge on the periphery. Since the PC floor slab is intended to be waterproof by the PC slab itself, the reliability of waterproofing is still insufficient.

As a method for improving the waterproof performance, the upper left column of page 2 of the same publication describes that waterproofing is performed with asphalt. In addition, asphalt has a problem that the waterproofness deteriorates with time.

[0007] In order to solve such problems,
By the present applicants, a PC concrete floor slab body,
Japanese Patent Application No. 4-175468 (hereinafter referred to as a prior application) has proposed a PC floor slab having a waterproof pan with a back portion embedded in the upper surface of the floor slab main body.

0 is fixed, and the rising portion of the angle 18 is swallowed by the back hanger 20.

A trap 21 is connected to the floor of the waterproof pan 3. The floor is reinforced from the back side by a square pipe 22. This square pipe 22
Are fixed to the waterproof pan 3 by an FRP overlay.

An anchor 24 is fixed to the square pipe 22 by welding or the like. By providing the anchor 24, the bonding force between the waterproof pan 3 and the floor slab main body 2 is increased. Note that the waterproof pan 3 and the floor slab main body 2 are also formed by the anchor piece 17 and the anchor piece 25 described below.
The binding force with is increased.

On one side of the periphery of the waterproof pan 3,
A horizontal piece 26 is connected to the upper end of the rising piece 11, and a falling piece 27 and the anchor piece 2
5 is connected. A shower booth door frame 28 is mounted on the horizontal piece 26 with screws 29. 28a is a shower booth door.

An elastic layer 30 of a synthetic resin (for example, urethane) is attached to the back surface of the waterproof pan 3 by an appropriate method such as spraying. The concrete floor slab body 2 has reinforcing steel 36
Is buried.

The recessed portion surrounded by the rising piece 11, the wall panel mounting portion 12, the water piece 14, the horizontal piece 15 and the falling piece 16, and the concave portion surrounded by the rising piece 11, the horizontal piece 26 and the falling piece 27. Urethane 39 is thickly filled in the concave portions.
When the urethane is so thickly filled, the screws 19, 29
However, it stops at this urethane layer and does not reach concrete. Therefore, the screws 19 and 29 are easy to strike.

The rising piece 11, the wall panel placing portion 12, the water piece 14 and the horizontal piece 15, and the rising piece 11 and the horizontal piece 2
The iron angles 33 and 34 are fixed to 6 by an overlay so that screws work well. The first purpose of the angles 33 and 34 is to reinforce them. However, in the case of the angles 34, the lower edges thereof are bent to form anchor portions 34a, and the anchor portions 34a are embedded in concrete. By doing so, it also functions as an anchor for increasing the bonding force between the waterproof pan 3 and the concrete floor slab main body 2.
