Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of the present invention. The same members as those in the related art will be described with the same reference numerals.

First, the structure will be described. In the drawing, reference numeral 1 denotes opposite edge portions 12a, 12a of an adjacent outer wall board 12.
The outer wall board seam treatment material is bonded to a at both ends 12a.

As shown in FIG. 2, the outer wall board joint treatment material 1 has a band shape with a constant width L2 (about 5 to 20 cm).
A double-sided release paper 2, an adhesive 3, an adhesive transfer preventing layer 4, which is provided as necessary, a nonwoven fabric 5, a reinforcing coating 6, and the like are sequentially laminated.

Acrylic rubber, chloroprene rubber, urethane rubber (maximum thickness of about 1 mm at the center) is used as a material of the reinforcing coating 6, and nylon, polyester, rayon, acrylic, polypropylene, Vinylon, polyethylene, polyurethane, cupra (thickness of about 100 to 200 μm) and the like are used. As a material of the adhesive transfer preventing layer 4, polyvinyl chloride vinyl acetate, vinylidene chloride, and rubber (thickness of about 5 to 20 μm) are used. Acrylic resin, vinyl acetate (thickness: about 10 to 200 μm) or the like is used as the material of the adhesive 3, and further, as the material of the adhesive 3, vinyl chloride, vinyl chloride vinyl chloride, phenol resin,
Urea resin, epoxy resin, acrylic resin and the like are used.

The adhesive 3 is placed between the portion 3a bonded to the edge 12a of one outer wall board 12 and the portion 3a bonded to the edge 12a of the other outer wall board 12. A gap 3b having a constant width L1 (about 10 to 20 mm) is provided. The surface of the reinforcing coating 6 has a curved shape.

Next, a method of manufacturing the outer wall board joint processing material 1 will be described.

First, the nonwoven fabric 5 is placed on a release paper, and a reinforcing coating material is sprayed thereon (airless, air-airless, air spray) or applied in a curved shape by a roll coater, curtain flow coater, or the like. afterwards,
It is dried with hot air, infrared rays or the like to form a coating film to form the reinforcing coating 6.

Then, as a back surface treatment, an adhesive transfer preventing layer 4
Is dried by spraying the adhesive 3 on the dried and applied by a roll coater, a curtain flow coater or the like. At this time, the adhesive 3 is applied so as not to be applied in a range of 10 to 20 mm in width so as to form a gap 3b in the center. After that, double-sided release paper 2 is provided.

Next, a description will be given of a method of using the outer wall board joint treatment material 1 having such a configuration.

First, the outer wall board 12 is subjected to a base treatment, and then a primer is applied, and the outer wall board joint processing material 1 is attached. In this case, the double-sided release paper 2 is peeled off, and one part 3 a of the adhesive 3 is bonded to the edge 12 a of one outer wall board 12 and the other part 3 a is bonded to the edge 12 a of the other outer wall board 12. I do. Thereafter, the top coat 7 and drying are repeated from above, and the process is completed.

As described above, the adhesive 3, the nonwoven fabric 5,
It is only necessary to prepare the outer wall board seam treatment material 1 on which the reinforcing coating 6 is laminated, adhere the treatment material 1 between the adjacent both edge portions 12a, 12a, and apply the top coat 7 thereon. Therefore, the work of separately providing the cooling gauze 18 and the elastic sealing material 20 as in the related art is omitted, and the workability is improved. Moreover, the thickness of the reinforcing coating 6 does not vary, and cracks can be suppressed more than before.

Further, by providing a fixed gap 3b in the pressure-sensitive adhesive 3, the allowance for expansion at the gap 3b can be increased, so that the stress generated in the outer wall board joint processing material 1 can be reduced.

Further, since the surface of the reinforcing coating 6 is formed so as to exhibit a curved shape, when the top coating 7 is applied from above, the portion of the reinforcing coating 6 does not appear as a large step. Thus, the appearance quality is improved.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and there may be design changes within the scope of the present invention. Even this is included in the present invention. For example, in the above embodiment, the pressure-sensitive adhesive migration preventing layer 4 is provided, but it is not particularly necessary. Further, the adhesive 3 can be applied to the outer wall board 12 in advance. In this case
The seam treatment material 1 is obtained by applying the laminated nonwoven fabric 5 and the reinforcing coating 6 to each other.
Having an adhesive transfer prevention layer 4 if necessary.
The outer wall board 12 is attached to the edge 12a of the outer wall board 12.
It is used by bonding with an adhesive applied to the 12 side.
