Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel mounting structure in which a lower end portion of a wall panel is fixedly mounted on a flange formed on a peripheral portion of a waterproof floor pan.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a flange portion 2 having a substantially L-shaped cross section is formed on a peripheral portion of a waterproof floor pan 1.
There is known a wall panel mounting structure in which a lower end portion of the wall panel 4 is attached and fixed via a coupling 3 on the upper side.

[0003] In this case, the coupling member 3 is formed of a substantially U-shaped cross section opened upward, and a screw body 10 penetrating through the bottom surface thereof.
Is fixed by being screwed into the upper surface of the flange portion 2. The lower end portion of the wall panel 4 is fitted and mounted in the U-shaped opening of the coupling device 3, and the wall panel 4 is formed of a thin plate material and formed in a flat box shape opened backward. A heat insulating material 19 is stuck on the inner rear surface, and the same wall panel 4
A sealing material 30 is filled in a gap between the front surface of the connector 3 and the upper edge of the front end of the coupling 3.

[0004]

However, in the above-mentioned prior art, the lower end portion of the wall panel 4 is connected to the fastener 3.
The lower end portion of the wall panel 4 is not securely fixed because there is a possibility that the lower end portion of the wall panel 4 may rattle or come off. In addition, a sealing material is provided at a gap between the front surface of the wall panel 4 and the upper edge of the front end of the joint 3.
In order to maintain the waterproofness between the lower end portion of the wall panel 4 and the flange portion 2 of the waterproof floor pan 1 by filling the sealing material 30, the work of filling the sealing material 30 is troublesome. It requires time and skill, and the work requires skilled skills, and the finished appearance tends to vary.
It is also conceivable that the water that has entered the gap between the upper surface of the flange portion 2 leaks from the screwed portion of the screw body 10,
Sufficient waterproofness was not secured.

Therefore, the applicant has considered that the lower end portion of the wall panel 4 is directly attached and fixed on the flange portion 2 of the waterproof floor pan 1 with the screw body 10 without the intermediary of the coupling member 3.
That is, as shown in FIG. 5, the connecting piece 9 vertically provided on the rear side of the lower end of the wall panel 4 is placed upright on the flange 2, and the screw body 10 is penetrated from the front of the connecting piece 9. And screwed into the vertical wall 8 of the flange portion 2 to secure the lower end surface of the wall panel 4
A wall panel mounting structure in which a packing material 18 is fitted in a space between the upper surface 12 of the flange portion 11 and the packing material 18 to seal the space is considered.

In this case, the connecting piece 9 at the lower end of the wall panel 4 is directly attached and fixed to the vertical wall 8 of the flange 2 with the screw body 10, so that the lower end of the wall panel 4 is loose. It is firmly fixed and the packing material 18 is fitted, and the dry construction of fitting the packing material 18 makes it easy to waterproof the space between the lower end surface 11 of the wall panel 4 and the upper surface 12 of the flange portion 2 and has a good finished appearance. It is applied to

[0007] However, in this case, the screw member 9 is mounted on the flange 2 with the connecting piece 9 of the wall panel 4 standing upright.
When the screw 10 is screwed in, the engaging piece 9 is easily displaced and moved on the upper surface 12 of the flange portion 2 and its position is hard to be determined, and the screwing operation must be performed while holding the front surface of the wall panel 4 by hand. However, the work of attaching and fixing the lower end portion of the wall panel 4 becomes difficult.

[0008] The present invention has been invented in order to solve all the problems in the prior art described above, that is, the problem is that the lower end portion of the wall panel is screwed on the flange portion of the peripheral portion of the waterproof panel. Provided is a wall panel mounting structure that can be easily and reliably attached and fixed, and furthermore, a space between a lower end portion and a flange portion of the wall panel can be easily sealed with a packing material to achieve a good appearance. That is.
