Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a three-dimensional wall surface in which three-dimensional pieces of arbitrary shapes are integrally formed on the inner and outer walls of a building or the like.

The method of embedding ceramic tiles, bricks, etc. on the exterior or interior walls of a building to create a wall with a three-dimensional effect is generally widely used, but placing and fixing ceramic tiles, etc. on the wall as specified requires a lot of skill. The construction costs are high and the construction period is long because a person is required, and there are some bases that bricks and ceramic tiles cannot be used on. There is a risk of bricks etc. peeling off or falling, and there is also a problem in terms of weather resistance.

In view of the current situation, this invention uniformly applies a joint material containing cement, silica sand, colored powder, glue, cationic synthetic resin, etc. to the surface of the base of a building, etc., which has been smoothed in advance. At the same time, before the applied joint material dries, a paper pattern made of cardboard with holes of arbitrary shape suitably arranged is pasted on the surface of the joint material, and then a material such as ceramics or bricks is crushed on the surface of the paper pattern. The main material is made by mixing aggregate with cement, cationic synthetic resin, coloring agent, etc., and is applied to an appropriate thickness.
After the surface of the main material has dried to the point where it does not sag, the paper pattern is peeled off from the base, and a number of three-dimensional pieces are made to protrude integrally onto the base through the joints, and after the main material has dried, a top coat is applied to the surface. The purpose of this is to create a three-dimensional wall surface.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, inspect the surface of the wall on which you want to construct the three-dimensional wall (hereinafter referred to as the "base"), check whether there are any severe unevenness on the base, and if there are any severe unevenness, smooth the surface with a commercially available primer, etc. After repairing the base 1, apply a joint material 2 made of a mixture of cement, silica sand, glue, acrylic color liquid, cationic synthetic resin liquid, etc. to the entire surface of the base 1 using a trowel to a thickness of about 2 mm. to ensure even wear.

Then, the paper pattern 3 is pasted on the surface of the painted joint material 2. The paper pattern 3 is made by forming through holes 3a of any shape such as rectangular, square, circular, or a combination thereof into a thick paper such as cardboard to a predetermined joint width 3b.
It is formed by punching or cutting out leaving a mark, and before the joint material 2 applied to the base 1 dries, a paper pattern 3 is brought into contact with the surface of the joint material 2, and the paper pattern 3 is pasted while being lightly pressed with a roller or the like.

When attaching the pattern 3 to the joint material 2, if a vinyl tape with a width narrower than the joint width 3b is attached to the back side of the pattern 3, the pattern 3 can be easily peeled off as described below.

After pasting the pattern 3 on the joint material 2, the main material 4 is applied to the surface of the pattern 3 using a trowel, spatula, etc. to a thickness of about 3 mm to 10 mm uniformly over the entire surface. The main material 4 is made by mixing cement, perlite, silica sand, plaster, glue, etc. with aggregate made by crushing and molding materials such as ceramics or bricks, adding a coloring agent, and kneading it with a cationic synthetic resin. , sand and cement may be used.

After applying main material 4 to the surface of pattern 3, approximately 2
Dry the main material 4 for about 4 hours. The drying time naturally varies depending on the season, but once the surface of the main material 4 has dried to the extent that it is slightly dented, peel off the pattern 3 at the edge of the construction surface and remove the peeled joint area. After confirming that the main material 4 is dry without dripping, peel off the pattern 3 from the top to the bottom or from one end to the other on the left and right, and the main material coated on the through hole 3a of the pattern 3 can be removed. 4 is the same as joint material 2
The main material 4 painted on the joint width 3b is peeled off together with the pattern 3, and the part is fixed to the base 1 as a solid piece 4a, 4a... A joint 5 is formed on the top.

In addition, when peeling off the paper pattern 3, carefully peel it off using a cutter knife or the like so that no part of the joint width 3b is left behind, and repair the splashes on the main material 4 as necessary. In addition, when applying the main material 4 to the surface of the pattern paper 3, cover plates 6 having the same shape as the through holes 3a are fitted into the through holes 3a of the pattern paper 3, and after the main material 4 is applied, these cover plates 6 are peeled off. However, by removing the main material and painting the main material in a different color, you can add an accent to the resulting wall surface.

After completely removing the pattern 3 and exposing the joints 5 and three-dimensional pieces 4a, 4a..., the whole is left to dry for about 24 hours, and when the main material 4 is completely dry, acrylic is applied to the entire wall surface. The wall surface is finished by spraying a topcoat material made of synthetic resin or the like.

In addition, when constructing a three-dimensional wall of any shape, the use of a pattern made of cardboard allows the pattern itself to absorb moisture from the main material to which it is applied, thereby speeding up the drying of the main material and shortening the construction period as much as possible. At the same time, this is to promote drying of the main material at the periphery of the through hole formed in the paper pattern and to prevent the main material from sagging.

As described above, according to the present invention, it is possible to easily and simply construct a three-dimensional wall surface similar to that using ceramic or brick for the inner and outer walls of a building or the like.

In particular, in this invention, since cardboard is used as the paper pattern, the paper pattern itself has a certain degree of rigidity, making it extremely easy to handle. By doing so, it is possible to form a wall surface that is clearly divided through joints and has an excellent three-dimensional effect.

In addition, since the pattern is made of cardboard, it has extremely good adhesion to the joint material, allowing for reliable adhesion, quickly absorbing moisture in the main material, and speeding up the drying of the main material, allowing for short construction times. It has many practical advantages, such as being able to prevent the main material from sagging.
