Description

[Detailed Description of the Invention] The present invention relates to a wall board that can give a wall surface a three-dimensional effect with unevenness.

Conventionally, in order to give a wall surface a three-dimensional effect with unevenness as shown in FIG. 1, a wall board 7 as shown in FIGS.
By attaching to the wall, the protruding portion 9 of the wall plate 7
The walls had an uneven pattern.
That is, as shown in FIGS. 2 and 3, the conventional wall panel 7 has a rectangular frame-shaped reinforcing bar 2 attached to the back side periphery of a rectangular surface panel 1 having a protruding portion 9 in the center. A rectangular frame-shaped real crosspiece 3 is attached to the back side of the reinforcing crosspiece 2 with its position shifted relative to the reinforcing crosspiece 2, and a rectangular back plate 6 is attached to the back side of the real crosspiece 3, and the adjacent two sides of the front plate 1 are attached. The male part 4 of the real crosspiece 3 protrudes on the outside of the side, and the female part 5 is recessed on the inside of the other two sides of the surface plate 1. ... to the wall surface, by inserting and fitting the male portion 4 of another wall plate 7 into the female portion 5 of the wall plate 7, a large number of wall plates 7, 7 are installed.
... are connected to each other, and the protruding portions 9 of each wall plate 7 provide unevenness to the wall surface. However, in this wall board 7, since the thickness of the bar 3 is the same on the male part 4 side and the female part 5 side, the gap width between the thickness of the male part 4 and the female part 5 is the same. As a result, when connecting a large number of wall panels 7, 7, . . . , it is difficult to insert the male part 4 into the female part 5, resulting in poor workability.

The present invention has been developed in view of the above points, and allows the male part of one wall plate to be smoothly inserted and fitted into the female part of the other wall plate, thereby easily assembling a large number of wall plates. The object is to provide wall panels that can be connected.

That is, in the present invention, a square frame-shaped reinforcing bar 2 made of plywood is attached to the periphery of the back side of a square face plate 1, and a square frame-shaped real bar 3 made of plywood is attached to the back side of the reinforcing bar 2. By attaching the reinforcing bar 2 with a shift relative to the reinforcing beam 2, the male part 4 protrudes to the outside of two adjacent sides of the surface plate 1, and the female part 5 is formed inside the other two sides of the face plate 1, By attaching the back plate 6 to the back surface of the real crosspiece 3 and forming the back plate 6 on the side of the female part 5 from a soft material 8 which has a larger deflection deformation than plywood, the female real part 5
The above objective has been achieved by making it possible to widen the gap width.

The present invention will be explained in detail below with reference to Examples. Surface plate 1
is made of relatively thin rectangular plywood, etc.
As shown in FIGS. 4 to 6, a protruding portion 9 is formed in the center thereof to protrude toward the surface side. The protruding portion 9 is formed by processing a flat plate into a curved surface using a press or the like. The reinforcing bar 2 is formed into a rectangular frame shape by framing four reinforcing members 11 made of plywood or the like, and is attached to the periphery of the back side of the top plate 1. This reinforcing bar 2 is attached to the back surface of the top plate 1 so that its outer peripheral end surface is aligned with the outer peripheral end surface of the top board 1. The actual crosspiece 3 is made of plywood or the like 2
Male fruit 12, 12 and two female fruit 13, 13
It is formed into a rectangular frame shape by framing the reinforcing bar 2, and is attached to the back side of the reinforcing bar 2 at a shifted position from the reinforcing bar 2. The male material 12 is formed to have a slightly longer width dimension in the transverse direction than the female material 13, so that when the real crosspiece 3 is attached to the back surface of the reinforcing crosspiece 2, the two adjacent sides of the surface plate 1 The tip of the male fruit 12 protrudes outward to form the male fruit part 4, and the other adjacent two parts of the surface plate 1
The female fruit portion 5 is formed by recessing the female material 13 inside the side. The back plate 6 is formed of a plate material that has a greater flexural deformation than plywood, and may be made of, for example, a plastic plate that can be elastically deformed, resin-impregnated cardboard, or the like. This back plate 6 is formed into a rectangular shape with a slightly wider area than the front plate 1, and is attached to the back side of the actual crosspiece 3 at a position slightly shifted from the front plate 1.
As mentioned above, the back plate 6 on the side of the female part 5 is made of a soft material 8 which has a larger bending deformation than plywood.

Therefore, when attaching the wall plate 7 formed in this way to the wall, the back plate 6 of the wall plate 7 is attached to the wall using adhesive or nailing.
Next, as shown in FIG. 7, other wall plates 7 are attached to the wall by inserting and fitting the male part 4 of the adjacent wall plate 7 into the female part 5 of this wall plate 7. In this way, a large number of wall panels 7, 7
... are connected and attached to the wall as shown in Figure 1. When inserting the male part 4 of the wall board 7 into the female part 5 of another wall board 7, the back plate 6 on the female part 5 side is made of a soft material 8 which has a larger deflection deformation than plywood.
Because the soft material 8 is pressed by the male part 4 of the plywood, it can bend and deform to the back side as shown by the phantom line in Figure 8, and the gap width of the female part 5 can be reduced. This allows the male fruit part 4 to be smoothly inserted into the female fruit part 5. This means that even if there is a slight variation in the thickness of the male fruit 12 and the female fruit 13 and the male fruit 12 is thicker than the female fruit 13, the gap width of the female fruit 5 can be easily widened. Therefore, the male part 4 can be inserted and fitted into the female part 5 without any problem. Furthermore, by forming the back plate 6 into a square shape and attaching it to the entire back side of the wall plate 7, the wall plate 7 can be reinforced with the back plate 6 to prevent warping and deformation. Since a gap 14 is formed between the plate 6 and the surface plate 1,
It is possible to improve heat insulation properties. Since the back plate 6 is formed to be slightly wider than the front plate 1, after a large number of wall plates 7 are attached to the wall by butting the back plates 6 of the wall plates 7 together, the adjacent wall plates 7, 7 A joint portion 10 will be formed between the surface plates 1, 1, and since a protruding portion 9 is protruded toward the surface side at the center of the surface plate 1, it is necessary to provide these unevenness to the wall surface. It is possible to create a three-dimensional effect. In the above embodiment, the back plate 6 is formed of a rectangular plate material, but it may also be formed of a frame material having approximately the same shape as the reinforcing bar 2 and the real bar 3. In this case, the back plate on the female part 5 side The board 6 is formed of a soft material 8 which has a larger deflection deformation than plywood.

As mentioned above, the present invention attaches reinforcing bars to the periphery of the back side of the top plate, and attaches the actual bars to the back of the reinforcing bars in a manner that is shifted from the reinforcing bar. The male part of the wall board was made to protrude, and the female part was formed on the inside of the other two sides of the face plate, and the back board was attached to the back of the real crosspiece. Not only can it be inserted and fitted into the real part to connect multiple wall panels and be attached to a wall, but the back plate on the female part side is made of a soft material that has greater deflection deformation than plywood. When inserting the male part of another wall plate into the female part, the male part is smoothly inserted into the female part by bending and deforming the soft material to easily widen the gap between the female parts. This makes it possible to improve the workability of installing wall panels.
