Abstract

PROBLEM TO BE SOLVED: To make it possible to enhance and keep the beauty of an outward looking without forming burrs on both sides of a joint after the execution of work. SOLUTION: Two sheets of coated paper 3 and 4, which are templated like the shape of the surface, are pasted on the front surface of a pattern member 2 by way of a bonding agent while release paper bonded on the rear surface by way of the bonding agent 5, is pasted, thereby forming a joint formation member 1 in four layer-structure. When this joint formation member 1 is used, the front coated paper is arranged to be formed with the coated paper 3 and 4 in two layer-structure. Due to this construction, the surface of a spray paint material after it is sprayed, is arranged to be nearly as high as the surface of the coated paper 4 and then the spray printing material is sprayed so that the coated paper 4 may be exposed. Then, the coating material is leveled along the joint with a crowbar and then the coated paper 4 is stripped off so that the spray coating material may be sprayed again to a thin coat on the whole.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a joint forming member and a joint forming method for forming a joint pattern on a surface such as a wall surface or a floor surface.

[0002]

2. Description of the Related Art A joint forming member is used in order to give a feeling of finishing of bricks or tiles by using a spray coating material. As shown in FIG. 8 (A), a conventional joint forming member has a release paper 102 adhered to the back surface of a mold member 101 formed of a foamed material in a strip shape via an adhesive, and the release paper on the front surface as well. There is a three-layer structure in which 103 is attached (see Jpn. Pat. Appln. KOKAI No. 4-15484).

[0003]

The construction work using this joint forming member is carried out as shown in FIGS. 8 and 9. First, after adjusting the foundation of the construction wall surface 104, the release paper 102
Is peeled off and the mold member 101 is attached to a desired position on the construction wall surface 104 (FIG. 8A). Then, the spray coating material 105 is uniformly sprayed on the entire surface of the construction wall surface 104 as shown in FIG. While the spray coating material 105 is undried, the release paper 1
No. 03 is peeled off (FIG. 9 (A)), and then the mold member 101 is removed after the spray coating material 105 is sufficiently dried to form the joint 106 (FIG. 9 (B)).

Since the spray coating material 105 is sprayed so as to uniformly cover the entire surface of the construction wall surface 104 including the mold member 101, a certain thickness of the spray coating material 105 is formed on the release paper 102. Therefore, when the release paper 102 is peeled off, the portions along both sides thereof are lifted up, so that after the spray coating material 105 is dried, burrs 107 are formed on both sides of the joint 106, which impairs the aesthetics of the finish. there were.

Then, the present inventor has conducted extensive studies for the purpose of eliminating the drawbacks of the conventional joint forming member and the joint forming method, and as a result, burrs are not formed on both sides of the joint after the construction and the appearance is improved. The present invention has completed a joint forming member and a joint forming method capable of achieving good results.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is to laminate two sheets of coated paper on the surface of a mold member having a shape of forming a joint groove so that they can be peeled off via an adhesive. In addition, the joint forming member is characterized in that an adhesive is applied to the back surface of the mold member and a release paper is releasably attached to the back surface.

In this joint forming member, the coated paper is doubly laminated and adhered to the surface of the mold member, so that the work of applying the finish forming member can be performed twice. Therefore, the heights of the surface of the finished surface forming material and the surface of the release paper can be easily made substantially uniform, and the surface of the finished surface forming material and the joint edges can be easily finished.

Further, according to the present invention, when the finish forming material is applied to the surface to which the joint forming member is adhered, the surface of the joint forming member is exposed from the surface of the finish forming material after application. The first coating step of applying a finishing surface forming material with a metal trowel along the joint forming member with a trowel, and then sticking to the outer surface of the joint forming member. The step of peeling off the coated paper which has been formed, the second step of applying the finishing surface forming material over the entire surface to be processed, and the second applying step of the finishing surface forming material and the aforementioned finishing surface forming material. Is a non-dried state, a joint forming method comprising a step of peeling the coated paper adhered to the lower surface of the joint forming member, and a step of removing the joint forming member after the finishing surface forming material has dried. And

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a joint forming member and a joint forming method according to the present invention will be described below with reference to the drawings.

The joint forming member 1 of the present invention comprises two sheets of a coated paper 3 and a coated paper 4 formed on the surface of a mold member 2 formed by forming foamed polyethylene in a band shape or other arbitrary shape in the same manner as the surface shape. The coated paper of 1 is sequentially attached via an adhesive coated on the back side of the coated paper, and the release paper 5 on the back side of which the pattern is formed in the same manner as the back side is attached via the adhesive coated on the back side of the mold member 2. The entire structure has a four-layer structure by being attached.
A part of it is shown in FIG.

The mold member 2 is for forming a joint pattern on the surface to be constructed, and can have a shape corresponding to the joint shape to be formed, but it is a long material having an appropriate length. Is preferred.

In addition to foamed polyethylene, the material of the mold member 2 may be foamed material such as polypropylene, polystyrene, polyurethane, polyvinyl chloride, or the like, which is not foamed and has a high flexibility such as plastic or rubber.

The covering papers 3 and 4 and the release paper 5 are all synthetic papers or the like, which are non-water-absorbing materials, and synthetic resin films such as polyethylene and polyvinyl chloride. When the thickness of the coated papers 3 and 4 is increased, the step between the joint forming member 1 and the surface of the spray coating material 7 which will be described later after peeling off the coated papers 3 and 4 becomes large, and the aesthetic appearance of the finish is impaired. Occurs. Therefore, it is preferable that the coated papers 3 and 4 are not so thick.

Next, a joint forming method using the joint forming member 1 will be described. First, after performing a repair treatment (base adjustment) to make the construction base 6 to be the surface to be constructed smooth, a waterproof paint (not shown) is uniformly applied by spraying or the like. After the waterproof paint is dried, the release paper 5 is peeled off and the back surface of the mold member 2 is attached to the desired position of the base 6.

Next, a spray coating material 7 for forming a finished surface.
Is sprayed over the entire surface of the base 6. This spray coating material 7
As the finishing surface forming material, for example, a skin type material containing an acrylic resin emulsion as a main component can be used. As shown in FIG. 3, the spray coating material 7 does not cover the coated paper 4 on the surface, and the surface of the spray coated material 7 has a height close to the surface of the coated paper 4 even after spraying, and the coated paper 4 is the spray coated material. Spray so that it is exposed from the surface of 7.

Before the spray coating material 7 dries, both sides of the coating paper 4 (portions that become joint edges after the work is completed) are covered with a metal iron (not shown) along the coating paper 4. The spray coating material 7 is leveled by scraping or the excess spray coating material 7 is scraped off so that the portion which will be the joint edge after the work is completed is finished neatly.

Subsequently, while the spray coating material 7 is not dried (immediately after spraying for about 1 hour), the coated paper 4 is peeled off to expose the coated paper 3 and the shallow groove 8 is formed (FIG. 4). . afterwards,
The spray coating material 7 is sprayed again. At this time, the spray coating material 7 is sprayed by an extremely thin amount such that the coating paper 3 is covered and the groove 8 is filled so that too much spray coating material 7 does not remain on the surface of the coating paper 3 (Fig. 5).

Next, as shown in FIG. 6, the coating material 3 is peeled off while the spray coating material 7 at this time is not dried, and the spray coating material 7 is removed.
After being sufficiently dried, the mold member 2 is removed. Then, as shown in FIG. 7, the joint pattern 9 is formed in the portion where the mold member 2 is removed.

The joint pattern 9 thus formed has no burrs and has a clear ridgeline and a beautiful appearance. That is, the spraying operation of the spray coating material 7 is divided into two stages so that the surface of the spray coating material 7 substantially coincides with the surface of the coated paper 4 at the time of the first spraying operation, and then a gold iron is used. This is because, since the spray coating material 7 is leveled, the spray coating material 7 that causes burr to be formed on both sides of the joint pattern 9 is eliminated. Moreover, by spraying the spray coating material 7 extremely thinly for the second time, This is because the thickness around the joint pattern 9 can be made uniform.

It is needless to say that the above-mentioned mold member 2 can be formed in various shapes, so that various patterns can be formed. Further, the construction surface may be a wall surface, a road surface of a road, a ceiling, a floor, an inner or outer surface of a building such as stairs, or the like. In addition to using the spray coating material as described above, it is possible to use cement, other coating material, spray gun, trowel, roller, etc. as the finish surface forming material depending on the application location or application of the work surface. Any coating material can be used.
