[0003]

[Problems to be solved by the device]

 By the way, according to the wall panel having the above-described structure, since the plate body is reinforced by the frame, the surface load on the panel is not evenly distributed and is concentrated only on the bonding portion between the plate body and the frame. . For this reason, a strong adhesive force or a binding force is required between the frame and the plate to obtain rigidity.

On the other hand, according to the wall panel having the above structure, since the planar reinforcement is used, the surface load is well dispersed and there is no problem in strength, but the panel weight is heavy, and therefore, the construction at the time of assembling the unit room is performed. There is a problem that the workability and the workability during transportation are poor.

Further, in the wall panel having the above structure, it is necessary to newly provide a mold for molding the panel every time the panel size, the surface pattern or the like is changed, which causes a problem that the panel cost becomes high. .

The present invention has been made in view of such circumstances, and an object thereof is to be lightweight and strong in strength, and moreover, even if there is a change in specifications such as a surface pattern, it can be easily performed. The purpose is to provide a wall panel having a structure that can be dealt with.

[0007]

[Means for Solving the Problems]

 A structure for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. The present invention relates to a wall panel 10 having a structure in which a back surface 11a of a surface material 1 and a reinforcing member 2 are bonded to each other. The reinforcing member 2 is provided with a plurality of ribs 21a, 21a, 21b, 21b which are substantially perpendicular to the back surface 11a of the surface material in a grid pattern, and on the adhesive surface side to the surface material 1. , The bonding reinforcements 22a, 22a, 22b, 22b having a surface that comes into contact with the back surface 11a of the surface material in a larger area than the rib intersections are integrally formed at the intersections of the ribs 21a, 21b. It is characterized by being formed.

[0008]

[Action]

 By providing the reinforcing members 22a and 22b for adhesion to the reinforcing member 2, the connection strength between the ribs 21a, 21b, ... Is increased and the adhesion area between the reinforcing member 2 and the surface material 1 is increased.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing the structure of the embodiment of the present invention.

The surface material 1 has a structure in which a decorative material 1b such as paper is attached to a plate-shaped base material 1a such as a flexible board, and the reinforcing member 2 is bonded to the back surface 11a of the surface material with an adhesive. The wall panel 10 is constructed as a whole.

The reinforcing member 2 is a resin molded product having a structure in which a plurality of ribs 21a..21a, 22a..22a that are substantially perpendicular to the back surface 11a of the surface material are arranged in a grid pattern. Adhesive stiffeners 22a and 22b are integrally formed on the surface where the ribs 21a and 21b intersect with each other on the side that is bonded to the surface material 1. Each of the bonding reinforcements 22a and 22b is a square or right-angled triangular flat plate having diagonal grid ribs 21a and 21b, and each front surface thereof is flush with the front surfaces of the ribs 21a and 21b. . Therefore, when the reinforcing member 2 having the above structure is fitted to the back surface 11a of the surface material 1, the ribs 21a ... 21a, 21b ... 21b and the reinforcing materials 22a, 22b for adhesion are brought into contact with each other, and The adhesive reinforcing materials 22a and 22b also serve as adhesive fixing surfaces to the surface material 1.

FIG. 2 is an exploded perspective view showing the structure of another embodiment of the present invention. In the embodiment shown in FIG. 1 above, the adhesive reinforcing material is provided at the intersection of the ribs, but in this example, the ribs 121a and 121b are arranged on the surface of the ribs 121a and 121b facing the rear surface side of the surface material 101. In addition, the reinforcing member 122a for adhesion composed of one sheet is integrally molded to form the reinforcing member 102 as a whole.

It should be noted that holes 132a, 132b, 132c are formed in the adhesive reinforcing material 102a at positions corresponding to the central portions of the respective rectangles of the lattice for weight reduction. Moreover, the size of these holes is gradually reduced from the upper and lower sides of the panel 110 toward the central portion in the vertical direction. In an assembled unit room, this generally has the maximum load on the vertical center of the wall panel, and the load gradually decreases toward the upper and lower ends of the panel. In consideration of this point, the adhesive strength of the central portion of the panel, that is, the contact area of the adhesive reinforcing material 122a is increased.

In the embodiments of the present invention described above, a structure in which a decorative material is attached to the upper surface of a plate-like base material is used as the surface material. However, the surface material is subjected to surface cosmetic treatment on the plate material itself. It goes without saying that it can be replaced with the above-mentioned surface plate material.

In addition to the structures of the two embodiments described above, the adhesive reinforcing material of the present invention has a surface to be adhered to the back surface of the panel surface material, and if it is lightweight, has any other shape. Those of can be applied.

[0016]

[Effect of device]

 As described above, according to the wall panel of the present invention, a reinforcing member in which a plurality of ribs are arranged in a grid pattern is adhered to the back surface of the surface material, and the surface material is formed at the intersection of the ribs. Since the adhesive reinforcing material having the surface that contacts the back surface of the rib is provided, the strength of connection between the ribs is increased and the adhesive area between the reinforcing member 2 and the surface material 1 is increased, resulting in increased rigidity. . Moreover, since it is basically reinforced by ribs, weight reduction can also be achieved.

Further, since the surface material and the reinforcing member have different structures, even if the specifications of the surface pattern are changed, it is only necessary to change the surface material as a common constituent member of the reinforcing member, and such a specification can be obtained. You can easily adapt to changes.
