[0004]

SUMMARY OF THE INVENTION According to the present invention, a method and a structure for treating a joint portion which is a joint portion of such a covering material, and for changing the color tone and texture of the joint portion even in a covering material having a joint portion. Is to propose.

[0005]

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

FIGS. 1 and 2 show an external perspective view and a partially enlarged cross-sectional view centering on a bonded portion of a covering material when a covering material having no joint portion is stuck. FIGS. 3 to 5 show a plan view and a cross-sectional view of the procedure when the covering material having the joint / overlap margin is attached. FIG. 3 shows a state where only one sheet of this covering material is attached, and in FIG.
FIG. 5 shows a state in which three pieces are attached side by side, and FIG. 5 shows a state in which some pieces are attached and the joint portion is filled with the joint material with a partially enlarged cross-sectional view.

Explaining in order from the peripheral technology of the present invention, the covering material of the present invention is basically a conventional interior wallpaper having weather resistance and flexibility that can be applied to the outside of a building. A material that can be applied to the outside. Of course,
Needless to say, it can be applied to the interior as well, but it is certain that there are differences in design such as color, texture, shape, etc. between the materials generally used outside the building and the materials used inside the building. Is. The covering material according to the present invention is used by being attached to the inside and outside surfaces of the outer wall of a building, partitions, columns, floors, and the surface of structures.

The structure of the covering material generally has a base material portion and a decorative material portion as main elements. The main purpose of the base material is to support the decorative material, adhere to the base material, and follow the movement of the base material to alleviate the force applied to the cosmetic material portion.

Materials used for the base material include non-woven fabric, woven fabric, glass cloth, ceramic paper and synthetic paper. A sealing treatment may be performed on these materials with a resin reinforcement or a paint or a sealing material.

The decorative material part is made of natural stone, crushed stone, colored aggregate,
Colored plastic particles, plastic crushed particles molded from synthetic resin emulsion, solvent-type synthetic resin, hot-melt resin, etc., or finish coating materials mainly composed of these materials, or other elasticity, moisture permeability, waterproofness ， Used as a coating film for architectural finish coating materials that are characterized by weather resistance. In addition, a thin plate of metal such as stainless steel, aluminum, or copper, or a thin plate coated or plated on it can be used.

The composite of the decorative material portion on the base material portion can be achieved by bonding the two or by coating on the base material portion.

When the surface covering material is attached to a wall surface or the like, three types shown in the figure can be considered. One is the method shown in FIG. 1, which is a method of allocating the covering material on the wall surface and the like and sticking the covering material at a desired interval. In this case, since the joint portion is not taken into consideration in terms of waterproofness as it is, a joint material having waterproofness is required.

The pasting method shown in FIG.
First, the joint member is attached to the abutting portion of the cover material, and then the cover material is attached. In this case, since the wall surface etc. will be covered with the joint member or the covering material,
It is not always necessary for the joint material to be filled thereafter to be waterproof.

The method whose construction procedure is shown in FIGS. 3 to 5 is as follows.
The outer covering material having joints and overlapping margins is used and is attached. In this case as well, after allocating,
With the joint and overlap margin of the surface covering facing upward, it does not matter on the floor, but it will be applied in order. As the joint material used in this method, any material can be selected as long as the waterproof property can be secured only by attaching the covering material. As described above, it is needless to say that it is not necessary to consider waterproofness when the three attachment methods are used in a place where there is no rain such as indoors. Also, as a method of attaching the covering material, another method,
Nailing and screwing can also be used depending on the design and shape of the surface material.

After attaching the facing material, the joint material is filled in the joint portion. As a filling method, a caulking gun or a trowel is used, and the slurry or paste joint material is filled. After filling, if necessary, press the surface with a trowel or spatula to make it flat or U-shaped.

As the joint material, a conventionally known material may be used. Cement-based materials include cement and sand to be prepared on-site, and if necessary, powder emulsion,
Synthetic resin emulsions, viscosity modifiers, pigments, fibers, etc. added and kneaded together with water, or those already prepared. For resin-based materials, polyurethane-based, acrylic-based, butyl-rubber-based, usually called sealing materials, Materials such as silicone type and modified silicone type are used.

EXAMPLES In the examples, the present invention was carried out by the method of the procedure shown in FIGS. 2 and 3 to FIG.

In the example having the appearance shown in FIG. 2, first, a detached house having an ALC structure was selected as a base frame and construction was carried out around the entrance. For the surface covering material, use a modern art stone (brand name) made by Kikusui Chemical Co., Ltd. without joints, and use Kikusui tape for joints that will be attached before attaching the covering material. MA tape (trade name) manufactured by Chemical Industry Co., Ltd. was used. In the case of the MA tape, the main constitution of these is that the non-woven fabric is sealed with a dark gray paint to form a roll with a width of 50 mm. Modern Art Stone uses the same material as the above-mentioned MA tape for the base material, and for the decorative material part, a coating material containing a plurality of colored aggregates as coloring components is applied on the base material portion in two or three color spots. The whole surface is painted. Since the MA tape is processed with adhesive on the back side, it is attached as it is in accordance with the assigned black ink, and the adhesive is epoxy-modified acrylic resin-based adhesive on the adhesive, MA Bond E (trade name) manufactured by Kikusui Chemical Co., Ltd. Pasted using. As the joint material, a polymer cement-based joint material for tiles was used, and joint filling was performed using a joint iron.

Next, in the example showing the procedure of FIG. 3 to FIG.
The above-mentioned modern art stone with joints was used for the surface material. The base structure has an RC structure and was installed on the wall surface of this elevator hall. The same MA bond E as in the previous example was used as the adhesive for the facing material, and a modified silicone resin-based sealing material was used as the joint material. The joint material was constructed by using a caulking gun to finish the surface into a U shape.

[0020]

The following effects can be obtained by adopting the joint finishing method of the present invention. First, in terms of functionality, it improves the safety against rainfall immediately after construction. Further, it is possible to improve the durability of the adhesive to which the covering material is attached, and to conceal the discoloration when the adhesive that oozes out to the joint is resin-based. Further, the warp of the end portion of the cover material is eliminated, and the cover material is bonded to the base in a continuous form, so that the adhesive force as a whole is stably dispersed. In terms of design effect,
It becomes possible to select a joint material having a desired color and texture for the joint, and when the decorative material portion of the surface covering material is a pseudo-stone-like coating material, an appearance closer to that of natural stone can be obtained.
