Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to wall panels that constitute a wall surface by arranging a plurality of them in an existing building frame, etc., and in particular, decorative sheets for the mutual joint parts of the wall panels. Concerning improvements in coatings.

(Prior art) In recent years, when interior work is being carried out after the construction of a building frame, it is often necessary to change the space around the water, for example, a bathroom with a toilet bowl and sink attached to a bathtub, or a toilet bowl and sink for men and women. Spaces for multiple toilets, etc. to be placed side by side require a wide range of construction work, so we will need general-purpose wall panels, special wall panels such as panels with toilet bowls or sinks, etc. that are assembled into units in advance at factories, as well as plumbing and other facilities. It is defined by bringing equipment, etc. into the building, erecting the wall panels as appropriate, installing piping, equipment, etc., and creating a new inner room using the so-called prefabricated method, thereby simplifying construction. There is a tendency.

The prefabricated wall panels include those that are reinforced by adhering a wall covering base to the back side of a wall covering board with a decorative sheet pasted on the surface.Such wall panels, for example, have a metal base on the back side of the wall covering board. A frame is provided to add further reinforcement, and the base frame is used as a mounting portion to be attached to a foundation frame or the like provided apart from a building wall.

By the way, a plurality of wall panels are arranged side by side to form a wall surface, and the connection between the wall panels is as follows:
The joints are designed so that there are no gaps,
A first step is provided on the joint side side of one of the adjacent wall panels, in which the side end surface of the wall covering board is set back in the width direction from the side end surface of the wall covering base, and on the joint side side of the other wall panel, A second step is provided in which the side end surface of the wall covering board protrudes in the width direction from the side end surface of the wall covering base, and these steps are used as discontinuous joints.

According to the wall panel discontinuous joint structure that utilizes the above-described step, in the discontinuous joint of adjacent wall panels, the surface side edge of the wall covering base forming the first step and the wall covering plate forming the second step. overlaps with the back side edge of
A gap is created in the missing joint, and the foundation frame or building wall surface is not visible from inside the room.

In addition, if there is an overlap between the front side edge of the wall covering base forming the first step and the back side edge of the wall covering board forming the second step, the missing joint portion is located on the side of the other wall covering board. There may be a gap between the end faces; for example, when a plurality of wall panels are erected within a building frame to form a wall surface, the discrepancy between the erected width and the wall surface width can be absorbed by adjusting the gap width. .

(Problem to be Solved by the Invention) However, in the case of the wall panel having the missing joints described above, the wall forming the first level difference is caused by the gap between the side end surfaces of adjacent wall covering plates. Since the front side edge of the wall covering base is visible from inside the room, it is necessary to decorate the front side edge of the wall covering base.

Conventionally, as shown in FIG. 7, the decoration of the surface edge of the wall covering base forming the first step is performed by placing the side end surface 101x of the wall covering board 101 of one wall panel 100 on the side of the wall covering base 103. A first step m is provided by receding from the end surface 103y in the width direction, and the decorative sheet 105 attached to the surface of the wall covering board 101 makes the wall covering board 10
This was done by simultaneously covering the side end surface 101x of the wall covering base 103 and the surface side edge 103x of the wall covering base 103.

Further, as described above, the second step n is configured by making the side end surface 111x of the wall covering board 111 of the other wall panel 110 protrude in the width direction from the side end surface 113y of the wall covering base 113, The side end surface 111x of the wall covering board 111 and a part of the back surface following the side end surface 111x are covered with a decorative sheet 115 attached to the surface of the wall covering board 111.

If the first level difference m and the second level difference n are used to create a cut joint, mutual wall covering plates 101 and 1 can be connected from the room S to
The surface side edge 103y of the wall covering base 113 is not directly visible from between the side end surfaces 101x and 111x of the wall covering base 113.

However, in the method for decorating the first step m described above, the inner corner portion consisting of the side edge surface 101x of the wall covering board and the surface side edge 103x of the wall covering base is covered with a single decorative sheet 105. However, air is likely to be trapped between the corner of the inside corner and the back surface of the decorative sheet 105 during the covering operation, and it is difficult to decorate the inside corner with the decorative sheet 105 while expelling the air. As a result, decorative sheet 1 covering the inside corner
There was a problem with the 05 that a bulge was created due to air.

(Means for Solving the Problems) As a means for solving the above problems, the invention of the present application includes a wall covering board in which the front surface, left and right sides, and a part of the back surface following these sides are covered with a decorative sheet; A reinforcing material for wall covering boards, consisting of a wall covering base with a decorative base sheet of a predetermined width affixed to the edge of its front surface. The front side is glued to the back side of the wall covering board with only the width protruding out to form a wall panel.

(Function) According to the above means, a wall covering board whose side end surfaces and a part of the back surface following the side end surfaces are covered with a surface decorative sheet, and a wall whose front surface side edges are covered with a base decorative sheet. The decoration of the entry corner is completed when the base is fixed while forming the first level difference, and the difficult task of covering the corner of the entry corner, where air is easily trapped, with a single decorative sheet is completed. No need to do any work.
