DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention JP-A-59-106660 or JP-A-63-1253 in the prior art
In the invention described in Japanese Patent Publication No. 32, although a material applicable to the outer wall exterior surface is selected, even if there is no problem when it can be covered with a single sheet, it is considered that the waterproofness and the storage are taken into consideration. Since it is not, the joint between the seats has not been solved yet and it was not practical.

In the present invention, in consideration of waterproofness and storage,
An object of the present invention is to provide a facing material which facilitates joint between sheets and a finishing method using the same.

[0005]

In order to solve the above-mentioned problems, the covering material according to the present invention has a substantially rectangular sheet, and the adjoining two sides have overlapping portions which also serve as joints on the two sides. The back surface of the other two sides is coated with an adhesive material.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The covering material of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an example of a facing material. In the figure, 1 represents a decorative material portion, and 2 represents a base material portion that supports the decorative material portion. FIG. 2 is a diagram showing a partial cutout from the back surface of the cover material, and the adhesive material portion 3 adhered to the back surface of the base material portion and the release paper portion 4 covering the adhesive material portion 3 can be seen.
FIG. 3 is a sectional view taken along the line AA ′ in FIG. As shown in the figure, a decorative material portion 1 is formed on a base material portion 2 excluding joints and overlapping margins, and an adhesive material portion 3 and a release paper covering the adhesive material portion 3 are provided on the back surface of a side of a covering material having no overlapping margin. The part 4 is formed.

The base material portion 2 is preferably sufficiently thinner than the decorative material portion 1 and has a thickness of 2 mm or less. In addition, the width of the portion that serves as both the joint and the overlapping margin is 20 to 10 if the overlapping margin is sufficiently secured and the adhesion area when the outer wall outer surface is constructed is secured.
0 mm is appropriate. Suitable materials for the base member 2 include non-woven fabric, glass cloth, ceramic paper, and synthetic paper.

The decorative material part 1 is made of natural stone, crushed stone thereof, colored aggregate, colored plastic crushed particles, synthetic resin emulsion,
Those formed by solvent-type synthetic resin, hot melt resin, etc. are suitable, but stainless steel, aluminum thin plate, or those coated on it can also be used. In addition, the building material can be made into a decorative material part by coating the material on the base material.

The composite of the decorative material portion 1 on the base material portion 2 can be performed by bonding to a portion excluding the joint / overlap portion or painting. Next, the adhesive material portion 3 on the back surface of the base material portion 2 needs to be narrower than the joint and overlap margin portion, and the position where the adhesive is adhered is provided with the joint and overlap margin in the covering material. It is the side opposite to the side, and the material thereof is particularly preferably acrylic rubber-based or non-vulcanized butyl rubber-based, and silicone rubber-based, styrene-butadiene rubber-based, polyisoprene-based, polyvinyl ether-based, etc. Available.

The release paper forming the release paper section 4 is
Known materials usually used for adhesive tapes, labels, etc., especially those coated with fluororesin or silicone resin may be used. When attaching the surface covering material of the present invention to the inner and outer wall surfaces, the floor surface, etc., there is no up and down on the floor surface, so it suffices to start from any corner, but on the wall surface, there is usually no joint and overlap margin from below. With the same as the upper and lower sides shown in FIG. Various kinds of adhesives such as synthetic rubber, vinyl acetate, polymer cement, and acrylic rubber can be used as the adhesive for bonding the surface material to the wall surface or the like.

[0011] In sticking, the adhesive is protected by the release paper while the joint width is widened or the joint is not taken in the overlapping margin, and the release paper is peeled off to adhere the overlapped portion. . When considering waterproofness, start sticking from the lower part of the wall surface, and sticking it up toward the upper part so that the joint and overlapping margin part of the lower sheet is under the adhesive material part of the upper sheet, so that rainwater etc. Prevent intrusion.

FIG. 4 shows a perspective view of the appearance during the construction. In the example shown in this figure, first, allocation is performed according to the size of the covering material, and the parts are jointed in order from the bottom so that the joint / overlap margin portion appears in the table. FIG. 4 shows a state where the second step from the bottom is pasted and the third step from the bottom is started.

EXAMPLES In the examples, a covering material according to the present invention was manufactured and a construction test was conducted. In the covering material in the example,
A sheet in which an acrylic resin paint was coated on both sides of a polyester non-woven fabric with a knife coater was used as the base material 2.

The decorative material portion 1 was formed by curing the joint / overlap portion and the like on one surface of the base material portion 2 and applying the coating material according to the following Working Formulation 1 by spraying. The dimension of the covering material was 40 cm × 60 cm, and the joint and overlapping margin was 5 cm wide by exposing the coated non-woven fabric. As the adhesive material portion 3 and the release paper portion 4, a non-vulcanized butyl rubber sheet having a thickness of 0.2 mm and a width of 4.5 cm was used. 600 such covering materials
We made a piece of it and constructed it on a concrete block structure with a height of 2 m, and confirmed the workability and fit. As an adhesive at the time of construction, a polymer cement shown in the following Example 2 was used.

The result of the construction test is about 50 per person.

By applying the surface covering material of the present invention to the outer surface of the outer wall of a building, it is possible to achieve a waterproof construction with good fit. That is, conventionally, when a sheet-like surface covering material is applied to the outer surface of the outer wall of a building, since there is no overlapping part, the adhesive applied to the base will stick out from between the sheets, resulting in a beautiful finish. There wasn't. Further, in order to consider waterproofness, a sealing treatment between the sheets was required.

However, by applying the surface covering material of the present invention, the adhesive material does not stick out from between the sheets and the sealing treatment between the sheets becomes unnecessary. In addition, by exposing the overlap margin, which also functions as a joint and is colored in a desired joint color, with a constant width, it is effective in terms of design as a makeup joint.

Further, since the covering material of the present invention is completely waterproof immediately after construction, it is safe even against rainfall immediately after construction.
