Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to decorative finishing of the surface of a building, and the present invention relates to a method for making an uneven pattern (steps) formed by applying cement mortar directly as a decorative surface of the building surface. It is related to. [Prior art] Conventional methods for treating the surfaces of buildings (particularly exterior walls) include tiling, natural stone, imitation stone block, and metal plate finishing, as well as mortar, artificial stone, and natural stone particles. There are methods of painting or spraying the body etc. Among these, natural stone finishes are considered the best as they easily create a sense of luxury and solidity. This is a method in which after constructing a concrete wall, sliced natural stone is placed as an exterior material in a masonry style, following the conventional masonry method, and is usually carried out in the following manner.

In other words, vertical reinforcement was welded to the anchor reinforcement that had been embedded in advance during the construction of the concrete wall, horizontal reinforcement was attached to the vertical reinforcement, and dowel holes were created in the sliced stone and dowel reinforcement was inserted into these. Above, the horizontal reinforcing bars and dowel reinforcing bars in the mortar applied to the wall surface are tightened with a trigger. Most types of stone can be used for stone finishing, as the stone itself does not play a role in maintaining the strength of the building. However, on the other hand, something with beautiful colors,
Only materials that meet conditions such as being easy to process are used.

Marble, granite, andesite, sandstone, etc. are often used.

The surface finishes of these stones include embossed finishes and polished finishes. “Indian sandstone” is a special type. This is a semi-hard stone of ocher or khaki color, and because of its beautiful split surface, it is often used for stone finishing without much surface finishing.

Faux stone block cladding is also clad in the same way as the natural stone cladding described above, but instead of providing dowel holes, tension ribs can be placed in the block in advance and connected to the transverse reinforcement on the surface of the concrete wall. Unlike natural stone, it is easy to reduce weight, so high strength is not required for the reinforcement structure as a whole. However, in any case, the construction is very complicated and expensive, so a method of spraying a mixture of colored aggregate and colored aggregate has been devised and implemented. This made it possible to obtain walls that looked like granite or marble. [Problem to be solved by the invention] However, in order to apply a mixture of colored aggregate and colored aggregate to the surface of a building, the only way is to spray it with a spray gun. It was extremely difficult to express the bumpy finish, tortoiseshell cut, unevenness seen on the split skin, etc.

In addition, since the spraying material used is a mixture of resin and colored aggregate, if it is made thicker, vaporized components (water and solvent) will remain inside the thickness, and the strength will be significantly lower near the center, causing peeling. It is difficult to make the resin layer thick because it tends to be easily scratched, and there is also a limit to how thick the resin layer can be to create unevenness.

Therefore, for granite and marble, which have distinctive colors and which do not require any type of surface treatment (mostly have an almost smooth finish with no large irregularities), granular aggregates of various tones may be mixed in and sprayed. However, in cases such as Indian sandstone, for example, when the surface form of the stepped surface called ``warihada'' is valued more than the color (almost monochromatic) of the stone, it is adopted. In cases where there is a large number of bricks, there is no on-site spray finishing, or even pseudo-stone broncs, and the only option is currently to use natural stone for finishing.

[Means for Solving the Problems] Therefore, in view of the above points, the present inventor has finally perfected the method of the present invention as a result of intensive research, and its characteristics are as follows: ■ Method for surface treatment of buildings In this case, the first joint material is pasted on the surface of the building, the cement mortar coating material is sprayed evenly over it, and after drying for about 2 to 4 hours, the cement mortar coating material is applied with a trowel. Other methods for surface treatment of buildings include: applying the material in an uneven pattern, immediately removing the first joint material, and then spraying the synthetic resin finishing material over the entire surface and drying it. After painting the entire surface of the building to be treated, apply the first joint material, spray the cement mortar coating material evenly over it, let it dry for about 2 to 4 hours, and then apply it with a trowel. Apply a cement mortar coating material in an uneven pattern, then immediately remove the first joint material, apply a second joint material to the area from which the first joint material was removed, and then apply a synthetic resin finishing material. ■ In the manufacturing method of decorative material for pasting on buildings, after coating the entire surface of the base material, the second joint material is then removed and dried. Paste it, and spray cement mortar coating material evenly over it, 2
After drying for about 4 hours, apply a cement mortar coating material in an uneven pattern with a trowel, then immediately remove the first joint material and apply a second joint material to the area where the first joint material was removed. In other methods for producing decorative materials for attaching to buildings, the following steps are taken: Paste the first joint material on the surface of the joint, spray the cement mortar coating material evenly over it, let it dry for about 2 to 4 hours, and then apply the cement mortar coating material in an uneven pattern with a trowel. , immediately remove the first joint material,
After that, a finishing material made of Hewei resin is sprayed on the entire surface and allowed to dry.

Note that "buildings" here refer to buildings with walls made of concrete, cement mortar, concrete broncs, PC panels, etc.
It refers to something fenced off with LC panels, slate boards, etc., and can be anything other than a house, such as a fence or pillar. Furthermore, in the case of a house, in addition to walls, ceilings, beam bottoms, etc. are also surfaces that can be surface-treated by the present invention. Furthermore, for example, in the case of the surface of a concrete building, surface preparation is usually essential for surface treatment, but the present invention is not limited in this respect. That is, if the unevenness to be expressed is random unevenness, the portion that should have been adjusted in the conventional method can become part of the random unevenness. However, if there are missing spots on the surface of the wall or the like, or if separator marks are a problem, it is of course necessary to adjust the base, and it is up to you whether or not to adjust the base.

The "base material" is the basic part of a decorative board intended to be applied to the surface of a building, and is not particularly limited in terms of material, size, etc.

"Gout material" is essential when finishing natural stone, and is a masking material used to create joints that imitate natural stone. To obtain joints, apply material (described later)
is placed on the treated surface prior to spraying or smearing. Usually, duct tape is used, but it may also be a so-called "meji zelkova" or a substitute thereof.

The method of using the joint material differs depending on whether or not the color of the joint part is different from the color of the simulated stone part. In other words, when changing the color of the joint area and the color of the simulated stone area, the joint material should be attached and removed twice: once after spraying the cement mortar coating material and once after applying the cement mortar coating material. do. Therefore, the first joint material will be referred to as the first joint material, and the second joint material will be referred to as the second joint material. If you do not use a second joint filler, use FIi. Resin finishing material (f & description)
remains in the joint area, and in the end, the joint area and pseudo-stone area are all covered by this combination rIi. It will be covered with a resin finishing material. In that case (that is, when the joint material is used only once), it shall be called the first joint material in the same way as when it is used twice.

These two types of joint materials may be made of the same material (for example, duct tape for both), but the thickness of the first spraying is small, and the thickness of the subsequent application is uneven and thick in some places. Therefore, the second joint material may be made stronger. When using joint material twice, the entire painted surface applied to the building surface or board surface will remain exposed even after the completion of the precepts, making it easy to color-code the concave-convex portions and the joint portions, making it extremely easy to use. You can expect a beautiful finish. The "cement mortar coating material" is a material that creates the uneven pattern on the surface of a building, which is the most distinctive feature of the present invention, and is made of cement mortar. Cement mortar is usually obtained by blending Bortland cement, sand, and water, but of course it may contain other admixtures for various purposes.

In the present invention, this cement mortar coating material is
It is applied by spraying and smearing, and these two types may be basically the same.

However, since the blended amount of water passed through spraying and the blended amount of water passed through smearing are usually different, it is expected that there will be a similar difference in material mixing ratio.

Spraying should be done using a special equipment such as a spray gun, and painting should be done using a trowel (1 & above). Painting should be done after the spraying process is completed and it has been allowed to dry for 2 to 4 hours. Depending on the condition and material of the surface to be treated, the climate, and the precepts of the cement mortar, it is thought that less than 2 hours may be sufficient, or more than 4 hours may be necessary. It shall also include time. That is, this term can be said to mean that the first joint material is left to dry for a long time after being applied, rather than being removed immediately.

The term "trowel" refers to a metal fitting normally used for plastering, but in this specification it refers to a tool used when applying a coating material by hand. Therefore, there are no restrictions regarding the material or shape. "Gokai Resin Finishing Material" is a sprayed material that forms the outermost layer of the treated surface (excluding joint areas), and is more powerful than synthetic resin. Of course, various aggregates and admixtures may be added here as well. Moreover, the spraying operation of this finishing material may be performed multiple times to complete the finish, similar to a normal decorative finish.

[Example] The present invention will be described in more detail below based on the example shown in the drawings.

Up to this point, we have explained the method of surface treatment on the wall surface by on-site construction, but it is also possible to apply the surface treatment to slate boards and other substrates using the same method as for the wall surface, and apply this to the wall surface using mortar etc. It may also be pasted.

(Not shown) Furthermore, the second joint material may not be used, and the joint portion may be covered with the heiwei resin finishing material. (Not shown) [Effects of the Invention J As explained in detail above, the method for surface treatment of buildings and the method for manufacturing decorative materials for pasting on buildings according to the present invention have extremely high levels of effectiveness, which have various effects as described below. This is a great invention.

■ Concave and convex patterns, especially Indian sandstone-like finishes, which were considered impossible with conventional spray finishing, can now be achieved with a beautiful texture that is almost faithful to natural stone.

■ Since the convex portions of the uneven pattern are made of cement mortar instead of using composite resin like in conventional spray finishing, the strength is high and the possibility of peeling or cranking is extremely low. ■ Performed by the present invention The troweling operation is an operation for creating irregularities and is not an operation for obtaining a smooth surface as in the past, so it can be easily performed without requiring any skill.

(2) In the case of the method of attaching and removing the joint material twice, the joint part is exposed without being covered with the coating material or the finishing material, so color separation from the patterned part can be done effectively and easily.
