And a bathroom back side steel plate 2 bent into a shape capable of forming a sealed space fitted thereinto to form a sealed space, and a urethane inlet 4 is inserted through a hole opened on the side surface. The foaming-uncured urethane stock solution is injected and foam-cured, and at this time, the bathroom-side steel sheet 1 and the bathroom-backside steel sheet 2 are self-adhered with the urethane foam resin 5 to form a panel.

[0003] Since the appliances 8 (shower hangers, towel racks, etc.) used in the bathroom are often fixed with screws 9 from the bathroom side, as shown in FIG. In many cases, the plywood 7 is inserted in a place where the screw penetrates.

[0004]

In the above-mentioned conventional molding method, the urethane foam resin 5 must be injected into each of the panels, and the urethane foam resin 5 does not leak from the enclosed space, so that the side of the bathroom side is not exposed. Decorative steel plate 1 and bathroom back side steel plate 2
It was necessary to seal the fitting part of the above and the corner part of the bent steel plate on the back side of the bathroom with a sealing material 3 for preventing uncured urethane resin from leaking.

In order to prevent the urethane foaming pressure from waving on the decorative surface of the interior side of the bathroom, when the foamed urethane resin 5 is injected and cured, a high rigidity plate 6 for maintaining a smooth surface such as an aluminum plate or an iron plate is used to cover the front and back of the panel. It was necessary to hold it until sandwiching and curing were completed.

[0006] Further, a wall mounting device 8 used in a bathroom.
(Shower hangers, towel racks) are often fixed with screws 9 from the inside of the bathroom. Therefore, in order to obtain a screw holding force, there is a case where a reinforcing tree 7 is inserted in advance in a place where the screws 9 penetrate in a closed space. There were many.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a decorative steel sheet on the bathroom side.
An object of the present invention is to manufacture and provide a steel plate sandwich panel for bathroom characterized by having a structure of urethane foam resin 5 / bathroom steel plate 2 on the back side of the bathroom.

Means for Solving the Problems To achieve the above object, a first aspect of the present invention is to provide a composite plate 13 comprising a urethane foam resin 5 formed in a flat plate and a steel plate 2 on the back side of a bathroom. It is characterized in that it has a structure in which a bathroom interior side decorative steel sheet 1 bent in a direction opposite to the inner side is bonded with an adhesive 15. According to the present invention, by bonding the composite plate 13 and the bathroom interior side decorative steel plate 1, equipment for sandwiching the front and back of the panel with the high-rigidity plate 6 for maintaining a smooth surface is not required to maintain smoothness. Uncured urethane resin leakage prevention sealing material 3 for preventing urethane resin from leaking out
Also do not need.

Further, in the present invention, since the steel plate having a rust-preventing property such as a coated steel plate or a hot-dip galvanized steel plate is used as the steel plate 2 on the back side of the bathroom, the steel plate does not rust against moisture in the bathroom.

Further, since the urethane board itself has no water absorbability, a reaction hardening type is used for bonding the bathroom interior side decorative steel sheet 1, the urethane foam resin 5 and the composite panel 13 composed of the bathroom rear side steel sheet 2. Although the urethane-based adhesive or epoxy adhesive had to be used, the adhesive of the composite plate 13 was used when the composite plate 13 composed of the bathroom-side decorative steel sheet 1, the urethane foam resin 5, and the bathroom-rear side steel sheet 2 was bonded. By using the paper 14 on the surface in contact with the adhesive, an inexpensive and easy-to-use emulsion adhesive 15 can be used.

Further, by setting the basis weight of the paper 14 to be bonded to 100 to 400 g / m ² , it is possible to ensure a required water absorption of the emulsion adhesive 15, and to make the bathroom interior face-up. The adhesive force of the emulsion adhesive 15 for bonding the steel sheet 1 and the composite board 13 made of the urethane foam resin 5 and the bathroom back side steel sheet 2 can be further strengthened.

Further, in the fifth aspect, the thickness of the steel plate 2 on the back side of the bathroom is set to 0.5 mm or more, so that the screw 9 for fixing the wall mounting device 8 such as a towel rail or a shower hanger with the screw 9 is provided. Since the fixing strength is obtained, it is not necessary to insert the reinforcing tree 7 in a predetermined position in advance and maintain the screw fixing strength.
