There are generally two types of exterior wall refurbishment methods, namely repainting and relining. The present invention is an example of a relining type using a new outer wall material.

First, the outer wall remodeling wall material A of the first embodiment will be described with reference to FIGS.

The outer wall remodeling wall material A of the present embodiment is a new outer wall material 1 to which the elastic body 2 is bonded to the back surface. Ceramic material board, metal plate, wood board, mortar, tile, etc. are used as the new outer wall material 1, and polyurethane foam, polystyrene foam, polo ethylene foam or glass wool, rock wool, cellulose fiber, etc. are used as the elastic body 2. Sheet is used.

The thickness of the elastic body 2 needs to be slightly different depending on the degree of flexibility, but is preferably about 1 to 20 mm. For example, a soft material such as a 30 times polyethylene foam sheet may be 2 to 3 mm.

Further, the elastic body 2 is projected and adhered while being displaced from the upper edge and the right edge of the new outer wall material 1. The outer wall refurbishing wall material A can be applied to a large plate type as shown in FIG. 1a, a vertical type as shown in FIG. 1b,
It can also be applied to the horizontal type shown in FIG. 1c.

Next, a method of refurbishing the outer wall using the wall material A for refurbishing the outer wall will be described.

When refurbishing the outer wall, the outer wall refurbishing wall material A is directly arranged on the surface of the existing outer wall material 3 that is in a non-treated state, and is fixed in order in the vertical and horizontal directions.

When fixing each outer wall remodeling wall material A to the existing outer wall material 3, the elastic body 2 is attached to the existing outer wall material 3 as shown in FIG.
Then, the nail 4 is struck from the surface of the new outer wall material 1 and fixed to the pillar (not shown) and the stud 5. still,
As shown in FIG. 2 and FIG. 3, another new outer wall material 1 is superposed and fixed on the edge portion of the elastic body 2 protruding from the side edge portion of the new outer wall material 1. By doing so, the elastic body 2,
The second seam is not exposed on the surface, and high waterproof performance can be exhibited.

When fixing the new outer wall material 1, if there is unevenness on the surface of the existing outer wall material 3, it is possible to absorb the unevenness by the elastic body 2, and thereby fix the new outer wall material 1 so as to be flush with each other. be able to.

As described above, in this embodiment, since the new outer wall material 1 can be fixed without removing the existing outer wall material 3 or adjusting the surface of the existing outer wall material 3, the new outer wall material 1 can be reduced in time and time. Can be realized. Further, since the existing outer wall material 3 is left as it is, it is possible to avoid inconvenience to the occupants during the renovation period.
