Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel made of fiber reinforced plastics (hereinafter abbreviated as FRP) used for a wall surface of a bathroom such as a unit bathroom, and more particularly, to a reinforcing structure of a panel body. In addition, the present invention is intended to improve the moldability, rust prevention, screw holding properties and on-site assembling workability as well as to increase the panel rigidity at low cost and low cost.

[0002]

2. Description of the Related Art Conventionally, in a bathroom wall panel of this type, as shown in FIG. 11, a panel body a is formed in a box-like shape by an SMC (sheet molding compound) molding method, As shown in FIG. 12, the reinforcing rib b has a reinforcing structure in which the reinforcing ribs b are vertically and horizontally integrated.

[0003]

However, in such a conventional bathroom wall panel, for example, the height H of the panel body a is 2,200 mm and the width W is 4 mm.
Since the thickness T is 25 mm, the thickness t1 of the outer peripheral side wall is as thick as 6 mm, and the thickness t2 of the surface is as thin as 2 to 3 mm, the surface is warped by forming the reinforcing rib b. And torsion are likely to occur.
Since a gap is formed between the joints of the panels, it is necessary to caulk the joints of the panels, which tends to cause mold and reduce the appearance.

In addition, since the panel body a has low bending strength and low screw holding properties, it is necessary to perform various reinforcements with a metal reinforcing member or a reinforcing plywood, so that the total weight increases and the cost increases. In addition, when the metal reinforcing member is exposed to the surface and reinforced, the rust is easily rusted and the appearance is deteriorated.

[0005] In addition, when panels are joined to each other, there is a problem in that the joint fittings are separately attached at the site, so that the assembly workability is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bathroom wall which is lightweight and inexpensive, is capable of improving moldability, rust prevention, screw holding properties and on-site assembly workability, and is capable of increasing panel rigidity. To provide a panel.

[0007]

In order to solve the above-mentioned problems, the present invention provides a panel-shaped F-shaped panel body.
It is configured to be formed by a RP surface member and a reinforcing member made of a plate-like metal attached to substantially the entire back surface side of the surface member.

In this case, a joint portion extending integrally from the reinforcing member to the outside of the surface member is formed on the joint end surface of the panel body by bending, and a foaming agent is used as an adhesive between the surface member and the reinforcing member. Or an expandable synthetic resin material.

The bathroom 100 is formed by joining a plurality of panel bodies 1 described later on a bathtub unit 101 and a washing unit 102 which are combined and arranged side by side to surround the peripheral wall surface of the bathroom. A dome-shaped ceiling panel 103 is joined to the upper part of the main body 1 in a mounted state.

As shown in FIGS. 2 to 4, the panel main body 1 has a box-shaped surface member 2 made of FRP.
And a reinforcing member 3 made of a plate-like metal
And the surface member 2
The reinforcing member 3 is bonded to the reinforcing member 3 via an adhesive 4.

A plurality of joints 31 and 32 extending integrally from both left and right ends of the reinforcing member 3 toward the outside of the surface member 2 are formed on the left and right joint end surfaces 1a and 1b of the panel body 1. The joint portions 31 and 32 are bent, and have a configuration in which the joint portions 31 and 32 are opposed to each other or are arranged so that the opposed positions are shifted from each other.

Further, the reinforcing member 3 is provided with positioning holes 33, 33, and these positioning holes 33, 3 are provided.
3 is engaged with positioning bosses 21 and 21 protruding from the back surface 2a side of the front surface member 2 to enable positioning of both at the time of assembly.

In the drawing, reference numeral 34 denotes a reinforcing rib formed by cutting and raising the reinforcing member 3 in the vertical and horizontal directions, and 35 denotes a hole, which is formed to enhance the strength of the panel body 1 by forming the reinforcing rib 34. On the other hand, the formation of the holes 35 reduces the overall weight of the panel body 1.

That is, in order to connect the panel main bodies 1 and 1 to each other, as shown in FIG. 5, the joint portions 31 and 32 of one panel main body 1 and 1 stand up from the other panel main body 1. This is performed by engaging the wall 11 so as to enclose it.

In order to join the panel bodies 1 and 1 to each other at a corner, in a case where the joint portions 31 and 32 are shifted from each other in facing positions, as shown in FIG. The joint 5 is formed by engaging the joint portion 31 of one panel body 1 with a locking hole 51 provided at one end of the joint member 5 and bending the joint at the other end. This is performed by engaging the rising wall 11 of the other panel body 1 so as to enclose the same at the portion 52. In the case of a configuration in which the joint portions 31, 32 are opposed to each other, FIG. As shown in FIG. 7, joints 31 and 32 of both panel bodies 1 and 1 are connected by pins 6, and packing 7 is fitted into the gaps.

Further, for example, in order to join the lower end 1c of the panel body 1 to the rising wall 102a of the washing unit 102, the end 3a of the reinforcing member 3 of the panel body 1 is extended outward as shown in FIG. At the same time, the overhanging end 3a is locked to the rising wall 102a of the washing unit 102.

Furthermore, in order to join the upper end 1d of the panel body 1 to the ceiling panel 103, as shown in FIG.

FIG. 10 shows another embodiment according to the present invention. As an adhesive 4 for bonding the surface member 2 and the reinforcing member 3, a foaming adhesive or a foaming synthetic resin such as urethane resin is used. A resin material is used, thereby improving the heat retention.

According to the present invention, by adopting the above-described structure, the panel body 1 has a box-shaped FR.
Since the surface member 2 is formed by the P-shaped surface member 2 and the reinforcing member 3 made of a plate-like metal and provided on substantially the entire back surface side of the surface member 2, the surface member 2 has the same warpage and twist as before. There is no reinforcing rib that causes the problem, and the moldability can be improved, and not only the reinforcing member 3 can sufficiently correct the surface member 2, but also the metal, FRP, and the metal can improve the screw retaining property. In addition, since the surface member 2 is made of FRP, it does not rust, and enhances appearance and durability.

Further, the joining end surfaces 1a, 1b of the panel body 1
Since the joint portions 31 and 32 extending integrally from the reinforcing member 3 to the outside of the surface member 2 are formed in a bent shape, it is not necessary to separately attach a joint fitting on site as in the past, and this reduces costs. And improvement of assembly workability can be achieved.

Further, the joint 3 to the reinforcing member 3
1, 32, positioning holes 33, 33, reinforcing ribs 34, and punched holes 35 can be formed simultaneously by press forming, and the reinforcing member 3 can be easily attached to the surface member 2 by a multi-stage press. In addition, productivity can be improved while reducing the overall weight.

Further, by using a foaming adhesive or a foaming synthetic resin material as the adhesive 4 between the surface member 2 and the reinforcing member 3 forming the panel body 1, the heat retention and the panel rigidity are improved. I can do it.

[0024]

As described above, the present invention is directed to a FRP surface member having a box-shaped panel body and a reinforcing member made of a plate-like metal provided on substantially the entire back side of the surface member. Since the surface member does not have a reinforcing rib that causes warping or twisting as in the past, the formability can be improved, and the reinforcing member can sufficiently correct the surface member. Not only possible, but also metal and FRP
In combination with the above, the screw holding property can be enhanced, and since the surface member is made of FRP, it does not rust and the appearance and durability can be enhanced.

According to the second aspect of the present invention, since the joint part 3 extending integrally from the reinforcing member to the outside of the surface member is formed on the joint end face of the panel body, the joint metal fitting can be formed in the field as before. There is no need to install separately
Thereby, cost reduction and improvement in assembly workability can be achieved.

Further, the joint portion, the positioning hole, the reinforcing rib, and the hole for the reinforcing member can be simultaneously formed by press molding, and the mounting of the reinforcing member to the surface member can be easily performed by the multi-stage press. Therefore, it is possible to reduce the total weight and improve the productivity.

Further, in the third aspect, the use of a foaming adhesive or a foaming synthetic resin material as an adhesive between the surface member forming the panel body and the reinforcing member improves the heat retaining property and the panel rigidity. Can be achieved.
