Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying method for mortar walls, foam concrete walls and the like.

[0002]

2. Description of the Related Art As a spraying method for mortar walls, a spraying method of lysine called "solid spraying" and a spraying tile construction method called "ball spraying" are mainly used. The former method of spraying ricin is carried out by spraying ricin, which is a resin paint such as vinyl acetate, acrylic resin, polyurethane, etc., with sand materials such as perlite and vermiculite, using a ricin gun. Prior to this, the adhesiveness with lysine is improved, and a primer or sealer may be used as a base coat to make it more accustomed.

In the latter method of spraying tiles, a mortar wall is primed with a primer or a sealer and then 5-10 mmφ
Crushing pottery, etc. using a gun with a diameter of 2), sizing the granules, spraying the main material mixed with water-soluble acrylic resin into a ball shape, then protecting the ball, polishing and waterproofing It is done by top coating with acrylic resin.

The above is a description of the spraying method for mortar walls. However, when the spraying tile method is applied to a wall constructed of factory-produced foam concrete building material, an undercoat is applied with a primer or a sealer. After that, a feeler is sprayed with an acrylic resin to block large and small holes on the surface, and then a ball is sprayed.

[0005]

The wall surface formed by the spray tile method is more durable than the wall surface formed by spraying lysine, and the surface has a beaded pattern, and the finish is beautiful. A first object of the present invention is to provide a spraying method that can obtain a more elegant wall surface than that of the spraying tile method, and a second object is to "joint" the mortar wall. It is intended to provide a spraying method in which a rectangular partition pattern called "."

[0006]

[Means for Solving the Problems and Actions] The spraying method for achieving the first object is the first step of undercoating the wall surface with a primer or a sealer, and the lysine spraying of the main material in which the resin is mixed with the aggregate. Second step of spraying in a solid shape using the air gun of No. 3, a third step of spraying compressed air from a nozzle while the sprayed main material has fluidity, and a fourth step of performing overcoating It consists of and.

According to this method, the sprayed portion spreads in a crater shape by spraying compressed air, and as a result, an infinite number of crater-shaped recess patterns are formed on the surface. The spraying method of the present invention can be applied to a mortar wall and a wall surface made of a foam concrete building material, but is particularly suitable for a wall surface made of a foam concrete building material. This is because the large and small holes on the surface are blocked by the spread of the material due to the blowing of the compressed air, and the conventional feeler blowing can be omitted.

The resin used in the present invention is
For example, acrylic resin is a preferred example. Another spraying method is the above-mentioned method, in which the first step of undercoating the wall surface with a primer or a sealer and the main material in which the resin is mixed with the aggregate are sprayed in a solid shape using an air gun for spraying ricin. A second step, a third step of blowing compressed air from a nozzle while the sprayed main material has fluidity, and a fourth step of grinding the surface with sandpaper or the like after the main material is solidified. And a fifth step of coating the ground surface with a roller.

According to this method, a beautiful pattern is formed by coating the ground surface. The spraying method to achieve the second purpose is as follows: a first step of applying a primer or a sealer to the mortar wall, a second step of applying a waterproof material for joints, and a double step on the waterproof material for joints. The third step of applying the adhesive tape laminated on the, the fourth step of spraying the main material mixed with resin into the aggregate in a solid shape using an air gun for spraying ricin, and the sprayed main material flows 5th step of spraying compressed air from the nozzle while maintaining the property, and 6th step of peeling off the tape on the upper side of the double-layered adhesive tape before the main material has dried It is characterized by comprising a seventh step and an eighth step of peeling off the adhesive tape after top coating.

According to the method of the present invention, a partition pattern that is sharp and distinctive due to the joint is obtained. By the way, when the same process is carried out by the conventional spray tile construction method, that is, the above-mentioned fourth step.
And when the same method as the above is carried out except that the step 5 is replaced with a spray tile step of spraying the main material in the form of beads, the material for the topcoat seeps out from between the protrusions of the beads, The border was blurred and a beautiful partition pattern could not be obtained.

EXAMPLE As shown in FIG. 1, felt 2 is placed on siding board 1.
Tension the wire mesh 3 on it with a staple, and then
Mortar cement 4 was applied. After curing, undercoat with a sealer 5 and then crush the pottery, etc., and sizing the aggregate obtained by sizing the mixture with a water-soluble acrylic resin, using a ricin spraying air gun to perform a solid spray 6 It was

Next, while the main material was fluid, a specially made nozzle in which 20 nozzles having a diameter of 1 mmφ were arranged at intervals of 5 mm was used to blow compressed air of 5 to 6 kg / cm ² . The spraying was performed while moving in the vertical direction or the horizontal direction along the wall surface from a position about 30 cm away from the wall surface. As a result, the main material diffused and penetrated into the fine cracks in the mortar, and the cracks were blocked.

After the main material was solidified, a top coat 7 was applied as a final finish. Spraying on the wall surface made of foam concrete 8 is also performed through the same steps as above. In this case as well, the main material entered the numerous holes on the surface by blowing the compressed air, and the holes were crushed. The photograph shown in FIG. 2 shows the wall surface after construction. FIG. 3 to FIG. 5 show another construction method. After the main material is solidified (FIG. 3) through the same work steps up to the step of blowing the compressed air of the construction method described above, the grinder equipped with the sandpaper is shown. The surface was ground by and the upper part of the mountain 8 was scraped off (FIG. 4). After that, the grinding dust adhering to the wall surface was scraped off with a brush or blown with compressed air for cleaning and removed. Then, a paint 9 having a color different from that of the main material was applied on the ground surface by rolling with a roller (FIG. 5).

The photograph shown in FIG. 6 shows the wall surface after construction. In this embodiment, the tile was sprayed and then ground with a grinder without applying an overcoat. However, grinding may be performed after the overcoat, and paints of different colors may be applied thereon. 7 to 10 show a method of forming a rectangular partition pattern with joints when spraying onto a mortar wall. A sealer is sprayed onto the mortar wall 11 to undercoat 12
After that, a waterproof coating 13 was applied to the joint-forming portion, and then a double tape 16 having a double-sided adhesive tape 14 and a tape 15 attached was attached to the coating 13. After that, as in the above-mentioned construction method, the main material obtained by crushing and sizing the pottery and the like and mixing the water-soluble acrylic resin with the aggregate was solidly blown 17 with an air gun for spraying lysine (FIG. 7). . Then, compressed air was blown before the main material dried to form a crater-like pattern on the surface (FIG. 8). Then double tape 16
After peeling off the tape 15 on the upper side (Fig. 8), top coat 1

The present invention is configured as described above and has the following effects. According to the spraying method of claim 1, since the sprayed tiles sprayed on the wall surface are diffused by the spraying of the compressed air and penetrate into the small tears formed on the wall surface, the cracks become inconspicuous. In addition, a crater-like elegant concave pattern is formed on the surface.

If the construction is performed on the wall surface made of foam concrete building material as in the spraying method according to claim 2, a large number of large and small holes formed on the surface are crushed by the inflow of resin at the time of spraying, and the feeler spraying is performed. The process can be omitted. According to the spraying method of the third aspect, a continuous colored pattern is formed and a beautiful wall surface is obtained.

According to the spraying method of the fourth aspect, a clean rectangular partition pattern can be obtained in which the boundary line of the jointed portion is sharp.
