SUMMARY OF THE INVENTION The present invention relates to a surface covering material which, even if it has flexibility as a whole sheet, cracks when it is bent and stuck on the corners at the corners and the corners at the corners. The present invention proposes a method for processing a corner.

[0005]

According to the present invention, in order to solve the above-mentioned problems, in attaching the covering material to the protruding corner portion, separate facing materials are used on both sides of the protruding corner line and the butt portion is formed on the protruding corner portion. Of course you can cut it according to the angle,
The butt-bonding is performed with a gap, and the protruding part is scraped off.

Further, it is also possible to pre-stretch the corner-squaring member proposed in another invention at the protruding corner portion and to continue the method of the present invention. The term “squared member” as used herein refers to a roll-shaped or fixed-length band-shaped member having only a base material, which is a constituent element of a surface covering material, as a main constituent element.

Hereinafter, a method for processing a corner in the present invention will be described with reference to the drawings.

FIG. 1 is a set of sectional views showing the processing procedure of the present invention. Fig. 1 (a) shows a skeleton 1 of a building or the like.

FIG. 1B is a cross-sectional view of a state in which the surface material 2 a on one side surface is attached using an adhesive 3. At this time, it is one of the features of the present invention that the end face of the body 2a of the exterior material 2a is attached with a distance of about several millimeters from the corner line of the body. FIG. 1C is a cross-sectional view showing a state in which another front cover material 2b is applied to the remaining corner of the remaining side by applying an adhesive to the back surface and the end surface of the front cover material. At this time, since the front covering material 2a previously attached is slightly away from the projected corner line, if it is adhered so that the ends of the front covering material 2b are rubbed together, the front covering material 2a is attached slightly below the projected corner line. In (d) of FIG. 1, after attaching the facing materials on both sides, the cosmetic material portion of the excess facing material that has protruded at the protruding corner and the protruding corner after the adhesive has been scraped off. It is sectional drawing which shows a finished state. Note that FIG. 1A shows that the facing material is composed of the decorative material portion 4 and the base material portion 5. Also, in FIG. 1, the surface of the surface material is drawn flat, but it can be used in the present invention even if it has irregularities, and it is more useful to use it under such conditions. .

Next, FIG. 2 shows the processing when the corner covering member 6 is used to improve the waterproofness and to improve the adhesion to the surface covering material at the outside corner before attaching the surface covering material to the outside corner. It is a group drawing by sectional drawing which shows the process of a procedure.

FIG. 2A is a cross-sectional view of the protruding corner portion in a state where the cornering member 6 is adhered to the protruding corner portion of the frame 1 such as a building using an adhesive 7. (B) of FIG.
Covering materials on both sides of the corner, including the top of the squared member,
As in the case of FIG. 1, a cross-sectional view is shown in a state where the end faces are staggered by several mm while being stuck together. The amount of shift varies depending on the thickness of the surface material, but is usually selected from an amount of 1/3 to 2/3 of the thickness. (C) of FIG.
FIG. 3 is a cross-sectional view illustrating a finished state of a protruding corner after the surface material and adhesive that have protruded at a rubbed portion at the end are scraped off.

[0011] Examples of the material of the base material portion or the stiffening member as the auxiliary material in the surface mounting material include nonwoven fabric, glass cloth, ceramic paper, and synthetic paper. These materials may be subjected to resin reinforcement or filling treatment. When used as a squaring member, it is used in the form of a roll having a width of 20 to 200 mm or a fixed-length band. The cosmetic material unit 2 converts natural stones and crushed stones, colored aggregates, colored plastic particles, and plastic crushed particles into synthetic resin emulsions, solvent-type synthetic resins,
The decorative material part can be formed by molding with a hot melt resin or the like, or by a coating film using a spray material for construction.

The composite of the decorative material portion on the base material portion can be achieved by laminating or painting.

[0013] The adhesive for upholstery or Kakubari member to the wall surface or the like, synthetic rubber, vinyl acetate, polymer cement, various adhesives such as an acrylic rubber can be used. Face material back side and the pressure-sensitive adhesive worked into Kakubari member back surface is made, and, in the absence consuming rain, it can be omitted adhesive application to the face material rear surface and Kakubari member back surface.

EXAMPLES In the examples, a surface covering material described below was manufactured and a construction test was performed. The form of the processing method of the out-of-corner was similar to the method of FIG. As the base material portion 5 of the facing material, a sheet in which dark gray acrylic resin paint was coated on both sides of a polyester nonwoven fabric with a knife coater was used. The decorative material portion 4 was formed by spraying a coating material according to Example 1 shown in Table 1 below on one surface of the base material portion 5 by spraying.
In addition, the dimension of the decorative part of the surface material was 40 cm × 60 cm. Joints and overlapping margins having a width of 5 cm are provided on two adjacent sides of the base material portion of the facing material in excess of the area of the decorative material portion. The method of the present invention was applied to a control panel base obtained by assembling the surface covering material having the above configuration into a prism having a side of 1.8 m, and the workability and fit were confirmed. Cutter knife (made by Tayama) and whetstone # 100
Was used. In addition, a roll-shaped member having a width of 15 mm was used as the square member 6. Table 2 below shows the adhesive used during construction.
The polymer cement shown in Formulation 2 was used.

[0015] In the construction, after laying out first, a cornering member is first attached to the corner, and then the surface material corresponding to the corner is stretched while being shifted by about 3 mm at the butt portion, and the joint width is adjusted in the remaining portion. I stuck it. Then, a portion that protruded after the adhesive was hardened was scraped off and finished with sandpaper # 60. The facing material hitting the corner was cut in accordance with the position of the protruding corner line, and cut off using a circular saw capable of adjusting the rear surface to an angle of about 45 ° C. according to the protruding corner angle of 90 ° C. . The result of the construction test was that the base material did not float even at the protruding corner portion, the adhesive did not protrude, and the fitting was neat.

In the second embodiment, the outer corner is finished with the facing material and the adhesive used in the first embodiment. In this example, a square finishing member was not used, and a clear finish paint was applied after attaching the surface covering material. In this case, a glossy finish was obtained in which the joint passed straight without slight swelling due to the angular member.

[0019]

According to the method of the present invention, a well-fitting finish can be achieved by applying the facing material to the protruding corner portion. That is, it is possible to prevent the concave portion of the decorative material portion from appearing as a gap when the facing material whose end is cut to half the angle in accordance with the corner angle is simply butted and stuck. In addition, if the cornering member is previously attached to the protruding corner portion, the waterproofness and the external stress are further improved.

Further, the method for treating a corner at the outside corner of the present invention relates to a surface covering material. In the conventional tiling work, a special tile called an accessory is required. By using this, it is not necessary to use a variety of surface covering materials.
