The first intermediate plate 3 is made of plywood, and the second intermediate plate 4 has a reinforcing paper 5 adhered to the surface of a base material A made of plywood, and a veneer 6 is further adhered to the reinforcing paper 5. The projecting plate 6 is made by pasting a sheet that takes advantage of natural wood grain onto a nonwoven fabric sheet, and is in the form of a sheet with a thickness of about 0.2 to 0.25+ nm.

An upper plate 7 is provided on the upper surface of both middle plates 3, 4 between both middle plates 3.4. The left side of the upper plate 7 is shorter than the second intermediate plate 4 and longer than the second lower plate 2. Further, the right side of the upper plate 7 is longer than the first intermediate plate 3 and shorter than the first lower plate 1. The upper plate 7 is formed by bending both left and right sides toward the back side, and the distance between the two bent portions 8 is equal to the distance between the two middle plates 3 and 4. Similarly to the second intermediate plate 4, the upper plate 7 also has a reinforcing paper 5 stuck to the surface of a base material 8 made of plywood, and a veneer 6 further stuck to the surface of the reinforcing paper 5.

As shown in FIG.
is provided. The projecting plate 6 of the second corner part 14 is the side surface 7b of the upper plate 7, and the first corner part 13
The upper projecting plate 6 forms a slope 7c that connects the side surface 7b and the upper surface 7a of the upper plate 7.

A soundproofing member 16 made of a polyester foam sheet is inserted into the space between the bent portions 8 of the upper plate 7, between the middle plates 3.4, and between the rain bottom plate 1.2.

Note that 17 is a large number of nails driven in the length direction of the wall material in order to fix the lower plates 1 and 2, the middle plates 3 and 4, and the upper plate 7.

Next, a method of manufacturing such a wall material will be explained.

First, a method for manufacturing the upper plate 7 will be described.

First, the reinforcing paper 5 is attached to the entire surface of the base material B with both sides of the base material B stretched out into a flat plate shape without being bent.

Next, a veneer 6 is pasted onto this reinforcing paper 5. Incidentally, the adhesive used to attach the reinforcing paper 5 and the veneer 6 to the plywood should preferably be flexible.

Then, the surface of the veneer 6 is sanded, then an undercoat is applied, it is further sanded, and finally a finishing coat is applied.

Thereafter, as shown in FIG. 4, two narrow V-grooves 910 are formed on the back surface of the base material B, leaving the reinforcing paper 5 and the veneer 6 portions on both sides of the upper plate 7, where the parts are to be bent. One wide V-groove 11 is cut out. That is, three grooves 9 and 10 in an isosceles triangular shape with an apex angle of 45° are cut out, one groove 11 in an isosceles triangular shape with an apex angle of 90° is cut out, and the main body 12 is located at the center of the base material B. , first and second corner portions 13 and 14, and a curved portion 15 are formed.

Using the cutout grooves 9, 10, and 11, bend the base material B, the reinforcing paper 5, and the veneer 6, and fold the one end surface 12 of the main body 12.
b and one end surface 13a of the first corner portion 13, the first corner portion 1
3 and one end surface 14a of the second corner portion 14,
The other end surface 14b of the second corner portion 14 and the one end surface 1 of the curved portion 15
5a are brought into contact with each other.

Then, as shown in FIG. 5, both bent portions 8 of the upper plate 7
A rain cover plate 3.4 is attached to the upper surface of the rain cover plate 3, and a rain cover plate 1, 2 is attached to the upper surface of the rain cover plate 3, 4.

Then, the lower plate 1.2, middle plates 3, 4, and upper plate 7 are fixed with nails 17.

Finally, the soundproofing member 16 is inserted into the spaces between the two folded portions 8 of the upper plate 7, between the rain cover plates 3° and 4, and between the rain cover plates 1.2.

Now, how to use the wall material of this example will be explained with reference to FIG.

To use the wall material of this example, as in the past, place the wall material X upright on the wall surface to be constructed, and then
Fix the wall material X on the wall by driving a nail from the surface to the wall.

Next, another wall material Y of the same shape is erected and applied on the left wall surface of the wall material X fixed on the wall surface, and the right edge of the second lower plate 2 of the same wall material Y is At the same time, the rightward protruding portion of the second middle plate 4 of the same wall material Y is overlapped on the first lower plate 1 of the wall material The right edge of the second intermediate plate 4 is brought into contact with the left edge of the first intermediate plate 3 of the wall material X. In this state, as in the case of the wall material X, nails are driven from the upper surface of the first lower plate 1 of the wall material Y to the animal on the wall surface to fix the wall material Y onto the wall surface.

Below, the wall material is fixed on the wall in the same way (.

In this way, in this embodiment, although the upper board 7 is made of plywood, a wall material that looks as if it was made from real lumber can be provided at a low cost.

Moreover, since the wall material is manufactured after pasting the veneer 6 on the plywood in advance, the veneer 6 is pasted so as to be continuous with the top surface 7a, side surface 7b, and slope 7C of the top board 7. Regardless, manufacturing is simple.

Furthermore, since the finishing coating of the wall material is performed at the manufacturing stage before the wall material is fixed to the wall surface, the coating work is simple.

In this embodiment, since the soundproofing material 16 is inserted into the space on the back side of the wall material, the soundproofing effect is also high.

Furthermore, since the veneer 6 is reinforced with the reinforcing paper 5, it is strong even when bent.

Note that the present invention is not limited to the above embodiments, and may be configured as follows.
