Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel for an indoor wall of a bathroom unit or the like.

[0002]

2. Description of the Related Art Conventional examples of panels for indoor walls such as bathroom units include A.I. A tile 3 is attached to a flexible board 2 reinforced by attaching a frame 1 such as a square pipe or the like, and a cement-based jointing material 4 is put in an joint portion (see FIG. 3), or formed and foamed on the back surface of the flexible board 2 Body 5

B.) and B.I. A plurality of tiles 3 are connected in series with the back surface facing upward with a joint gap formed therebetween, and a masking material is attached to the joint for the gap. A frame 6 and a pressing machine (not shown) are placed on the joint body of the tiles. The foam 7 is formed by injecting a foaming agent into the hollow portion of the frame 6 from the foaming agent injection port provided on the frame 6, and the tile 3, the frame 6, and the foam 7 are integrated without using an adhesive. After that, the pressing machine is removed, and a cement-based joint material 4 is put in the joint (see FIG. 5).

However, the conventional example has the following problems. That is, in the case of A, the weight increases by the amount of the flexible board, and in a generally used 800 mm × 2000 mm size, 3
It weighs more than 0 kg and is difficult to handle alone. The cement-based joint material has water absorption, and it is difficult to remove dirt. The heat-insulating material exposed to the back surface of the flexible board with a molded foam adhered to the back surface has a disadvantage that the heat-insulating material is exposed on the back surface and easily collapses due to handling or the like. In the case of B, it takes time and effort to attach the masking material to the joint gap, and it is difficult to cope with variations in tile dimensions. Extensive manufacturing facilities such as a foaming agent injection machine and a hot press are required. It is difficult to cope with high-mix low-volume production such as changing the size of tiles and panels. Since the foaming agent has elasticity, cracks are likely to occur at cement joints.
The panel tends to warp due to the difference in shrinkage / thermal expansion characteristics between the foam and the tile due to heat and moisture absorption.

Therefore, in the present invention, the joints are hardly stained,
The panel was made lighter, and the joint problems such as cracks in the joints and warpage of the panel, which were the conventional problems, while having heat insulation properties, were solved.
In addition, in providing heat insulation, it is possible to reduce productivity and equipment costs and to cope with high-mix low-volume production.

[0005]

In order to solve the above-mentioned problems, a panel for an indoor wall such as a bathroom unit of the present invention (hereinafter referred to as a panel of the present invention) is a box-shaped panel having a thin metal plate with one open side. On the inside of the molded body, a molded foam having a size that fits inside the box-shaped molded body is attached with an adhesive, and on the surface of the opened molded foam, a plurality of tiles are attached with an adhesive, The joint is finished with resin joint material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
m, aluminum-zinc alloy-plated steel plate is bent into a box shape with one side open, and the inner size is 800 mm x 2
It is molded into a size of 000 mm × 20 mm to obtain a box-shaped molded body 8 having one open side. The bent four corners may be left open, but may be closed by welding or the like. The metal plate that is the material of the box-shaped molded body 8 is not limited to a steel plate, and may be, for example, an aluminum plate. In the case of a steel plate, it is desirable to coat a metal such as aluminum or zinc. The thickness of the metal plate is 1.
The thickness may be 0 mm or less, but can be appropriately selected in terms of the strength and weight of the panel. The size of the box-shaped molded body 8 may be any size that matches the size of the bathroom unit.

[0007] Extrusion method styrene foam insulation board 1 type b
The slice is cut into 00 mm × 2000 mm × 20 mm to obtain a molded foam 9. Molded foam 9 is JIS A
What is necessary is just a heat insulation board suitable for 9511 foamed plastic heat insulation material. The molded foam 9 may have any size as long as it can be accommodated in the box-shaped molded body 8, but is desirably the same size as the inner size of the box-shaped molded body 8.

The box-shaped molded body 8 and the molded foam 9 are bonded with a solventless type reactive epoxy adhesive, and the tile 3 for the interior of the porcelain with a joint of 200 squares is joined to the molded foam 9 exposed on the open surface. It is bonded with a non-solvent type reactive epoxy resin adhesive so as to have a predetermined joint space. The adhesive used for bonding the box-shaped molded body 8 and the molded foamed body 9 may be a solventless moisture-curable urethane or modified silicone adhesive. The adhesive between the molded foam 9 and the tile 3 may be solventless moisture-curable urethane or modified silicone adhesive, synthetic resin emulsion type acrylic resin emulsion or SBR latex adhesive, or cement-based resin-mixed mortar. It is not desirable to use a material that is permeable to the tile 3 in order to prevent adhesion of dirt and penetration.

After filling the joint space with a joint material 10 of a solventless type reactive epoxy resin and finishing the joint with a joint finishing device, the joint on the tile surface is wiped off with a sponge or the like. The joint material 10 may be solventless moisture-curable urethane or modified silicon.

[0010] The finished panel is 3% less by weight than the panel according to prior art A using the same tile.
0% weight is reduced. In the heat insulation, the panel according to the conventional technique A using the same tile as the completed panel is cut into 200 mm squares, and the tiles are assembled into an open box with the tiles on the outside, and ice water is put therein. When the surface temperature change of the tile was measured using a surface thermometer at a room temperature of 30 ° C., the conventional technology A
The test panel dropped to 11 ° C after 5 minutes, but the finished panel maintained 25 ° C after 2 hours. Note that the panel according to the conventional technique A used a flexible board coated with a flexible agent so as not to absorb cold water because the inside becomes a flexible board having water absorption.

[0011]

As is clear from the above description, the indoor wall panel of the bathroom unit and the like according to the present invention has the following effects. Since the joint material is a resin material, the joint material can be provided with antifouling properties and can be free from joint cracks. By using a box-shaped molded product made of a thin metal plate and attaching tiles directly to the molded foam, it is possible to reduce the weight without sacrificing bending and bending strength without a reinforcing frame and flexible board. It became. By using a box-shaped molded product made of a thick metal plate, a tile that does not allow water to permeate from the design surface, and a resin-based joint material, it is possible to prevent water from entering the panel and prevent expansion due to moisture absorption of the foam. By restraining both sides of the molded foam with a material having small expansion and contraction, it has become possible to reduce the warpage of the panel. The use of a box-shaped molded body with only one side opened eliminates the exposure of the molded foam, and prevents the molded foam from being damaged during transportation or installation, thereby preventing its heat insulation performance and design from being deteriorated. Became possible. By attaching the molded foam to the box-shaped molded body, the productivity is good, the equipment cost can be reduced, and it becomes possible to add a heat insulating function to the panel that can cope with high-mix low-volume production.
