Abstract

PURPOSE: To join wall panels constituting a corner part of a building quickly in a fine workmanship by providing one of the panels with one edge part which is folded back to the rear surface, overlapping one edge of the other panel in flat form on this folded-back edge part of the first named wall panel, and coupling them by bolts and nuts. CONSTITUTION: A wall panel 1 made from steel plate is lined with a decorating layer 11 consisting of a paper impregnated with diaryl phthalate resin, and one side edge of this wall panel 1 is folded back at a right angle to the rear surface so that a folded edge 12 is formed, where through holes are bored at 150-mm intervals in the vertical arrangements. Another wall panel 2 is made in flat plate form and lined with a decorating layer 21 consisting of a paper impregnated over the whole surface with diaryl phthalate resin. and at one side edge 22 of this wall panel 2 is bored with through holes at 150-mm intervals in the vertical arrangement. The folded edge part 12 of the wall panel 1 is overlapped on one side edge 22 of the other wall panel 2 and fastened together by bolts 3 and nuts upon putting the through holes in two members in alignment, and thus the wall panels 1, 2 are joined together so that a corner part is accomplished.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for wall panels such as bathroom units.

[0002]

2. Description of the Related Art An inner surface of a wall panel is formed by forming a step or a recess at the inner end of a wall panel forming a corner portion to the extent that a joining member can be located, and joining the wall panel through the joining member. It is publicly known to bond wall panels by attaching a decorative material to, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-46547.

[0003]

However, in such a wall panel joint structure, it is necessary to position the joint member and each of the pair of wall panels forming the corners, and after the joint, When the decorative material is made of a flexible material such as a soft polyvinyl chloride sheet, the steps or recesses and the screw head shape are It has a problem that it is raised on the surface and spoils the aesthetics.

The present invention solves the above-mentioned problems of the prior art, shortens the joining work time, does not require an extra joining member, and when the decorative material for forming the decorative layer on the surface is made of a flexible material. Also, it is an object of the present invention to provide a joint structure of wall panels that does not spoil the appearance.

[0005]

According to the wall panel joining structure of the present invention, one wall panel of a pair of wall panels forming a corner portion is bent at one side edge at a substantially right angle to the back side. A bent edge is formed, and the bent edge is overlapped with and screwed to one edge of the other flat plate-shaped wall panel.

The material of the wall panel of the present invention is not particularly limited, and examples thereof include metal plates such as aluminum and stainless steel having a thickness of 0.3 to 1 mm. On the surface of the wall panel, a decorative layer may be formed by sticking a thermosetting resin-impregnated paper such as melamine resin or diallyl phthalate resin, a soft polyvinyl chloride sheet, or a decorative material such as tile.

It is sufficient for the decorative layer of the flat wall panel to be provided only on the portion excluding the portion contacting the bent edge that is not exposed to the outside after joining, but it is provided on the entire surface. Good.

When a pair of wall panels are joined together using bolts and nuts attached at substantially equal intervals in the vertical direction, the installation interval is preferably 200 mm or less. This is because if it exceeds 200 mm, the wall panel swells to both sides in the middle part and creates a gap.

[0009]

According to the present invention, one wall panel of the pair of wall panels forming the corner portion has one side edge bent toward the back side at a substantially right angle to form a bent edge. Since the bent edge is overlapped and screwed to one edge of the other flat wall panel, it is possible to join a pair of wall panels in a short time without using an extra joining member. The shape of bolts, nuts, etc. does not stand out on the surface of the wall panel.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an essential part showing one embodiment of a wall panel joining structure of the present invention.

In FIG. 1, reference numeral 1 denotes a steel plate wall panel provided with a decorative layer 11 made of diallyl phthalate resin-impregnated paper on the surface, one edge of which is bent at a right angle to the back side, A bent edge 12 is formed, and through holes (not shown) are formed in the bent edge 12 at intervals of 150 mm in the vertical direction.

Reference numeral 2 denotes a flat steel plate wall panel provided with a decorative layer 21 made of diallyl phthalate resin-impregnated paper on the entire surface, and one side edge 22 thereof has a vertical direction of 1
Through holes (not shown) are formed at intervals of 50 mm.

When performing the work of joining the wall panels 1 and 2,
The bent end edge 12 of the wall panel 1 is overlapped with the one end edge 22 of the flat plate-shaped wall panel 2, and the through holes formed in the bent end edge 12 and the side end edge 22 are aligned with each other to form a bolt. 3 may be inserted, fixed with a nut and screwed.

[0014]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is possible to shorten the work time for joining a pair of wall panels forming a corner portion by about 20%, and no extra joining member is required. Therefore, inventory management becomes easy. Further, even when the decorative material for forming the decorative layer on the surface of the wall panel is made of a flexible material, it does not spoil the appearance.
