Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a stone-like plastic block having a marble pattern or a granite pattern, which can be used for interior and exterior walls of buildings, gates, fences, etc. and can be easily constructed.

[0002]

2. Description of the Related Art Conventionally, as a method for forming a stone-like natural stone pattern on a building or the like, an actual natural stone has been used as a raw material, but since the natural stone is heavy, it is difficult to handle and the workability is poor. The processing is time-consuming and expensive, and its use is extremely limited. There is also a method of processing natural stone into a thin plate and stacking it with other materials such as concrete, but it is still not a universal material in terms of workability, workability, and price.

Coating materials made of various stone-like coating compositions which can be applied by spraying or troweling a stone-like natural stone pattern have been proposed, and artificial marble-like or granite-like stone-like materials have been put into practical use. There is. However, even if a natural stone pattern is formed on the wall surface by spraying a stone material or trowel coating, it can only give a flat monotonous color tone sensation, and it is not possible to express a natural stone pattern with a three-dimensional depth. However, since it is on-site construction, the construction cost is high, and the workmanship is highly inferior and the workman's skill level greatly varies.

There is also a method in which a natural stone pattern is formed on a sheet-shaped material with a stone material coating composition and this sheet is attached to the wall surface of a building or the like, but it also has a flat and monotonous color sense and has a three-dimensional depth. It was not possible to express the natural stone pattern.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is a method for manufacturing a stone-like plastic block that can express a natural stone pattern with a three-dimensional depth and that is lightweight and easy to construct and inexpensive. It is intended to provide a way.

[0006]

In order to achieve the above object, the stone-like plastic block of the present invention uses a hard foam plastic hollow block as a base material to form a tile pattern or an uneven pattern of arbitrary shape dimensions on its front and back surfaces. The stone-like pattern is expressed by applying a stone-like coating material having a marble pattern or a granite pattern on the surface.

Further, a coating material having a joint pattern is applied to the concave and convex portions formed on the front and back surfaces of the hard foamed plastic block, and this portion is masked to form a stone material having a marble pattern or a granite pattern on the convex surface. By applying a coating material or caulking, and then removing the masking of the concave portions, it is possible to give an appearance as if a stone tile or the like was pasted.

[0008]

The hard foamed plastic hollow block, which is the base material of the stone-like plastic tile block according to the present invention, is formed by extrusion molding or bead molding, and the plastic material may be any one that can be extruded or bead molded. Vinyl, polystyrene, phenol, polyisocyanurate and the like can be preferably used. The dimensions of the hard plastic hollow blocks may be the same as the concrete blocks, and because of their light weight, larger dimensions are possible than the concrete blocks.

The shape and size of the uneven pattern formed on the front and back surfaces of the stone-like plastic block are free and diverse, and square, rectangular, triangular, round, and other special shapes are possible. Also, the size thereof can be any size and shape from a small size of a mosaic tile to a large size tile of 1 m or more.

The stone-like coating material having a marble pattern or a granite pattern to be applied to the surface of the stone-like plastic block can be selected from general commercial products having excellent water resistance and weather resistance. It is composed of particles, a coloring material and additives. The binder is a synthetic resin solution, an emulsion, a reaction-curable synthetic resin solution, an inorganic polymer compound solution, or the like.

Construction of the stone-like plastic block according to the present invention is exactly the same as that of the concrete block. Stone-like plastic blocks are sequentially stacked on top of the foundation concrete, and reinforcing bars or aluminum molds are inserted into the hollow parts of the stone-like plastic blocks and concrete is placed there.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described with reference to the drawings.

Example 1 FIG. 1 is a sectional view of a stone material plastic block obtained by coating the surface of a polystyrene foam bead-molded hard foam plastic hollow block with a stone material coating material 2. The stone material is a granite-like special method finish coating material.
It was used.

EXAMPLE 2 Caulking was filled into the concave portions on the surface of a rigid foamed plastic hollow block formed by molding polystyrene beads, and a masking tape was attached to the concave portions. After the stone material coating material was applied to the convex portions, the masking tape was removed. As the stone material, a natural stone finish coating material with the product name "Dia Earl Stone" (made by Kowa Chemical Industry Co., Ltd.) was applied. FIG. 3 is a sectional view of the stone material plastic block of this embodiment.

FIG. 2 shows a front view of the shape and dimensions of the tile pattern on the surface of the stone-like plastic block of Example 1. A front view of the shape and dimensions of the surface of the stone-like plastic block of the actual rotation example 2 is the random layer masonry of FIG.
As described above, the stone-like plastic block according to the present invention can be formed in any shape and size.

FIG. 5 shows a mounting state of the hard foam plastic hollow block which is the stone-like plastic block of the first embodiment. The material of the rigid foam plastic hollow block is polystyrene. The hollow part of the hollow block is reinforced with reinforcement and is filled with concrete.

[0017]

The stone-like plastic block according to the present invention is lightweight and therefore can be easily installed. It was made possible that even unskilled people could easily perform the installation work without the need to use a water thread to bring out the horizon during construction.

In a method of spraying or troweling a stone material coating material on a wall surface or the like to form a natural stone pattern, or by applying a sheet or the like coated with the stone material coating composition to a wall surface to form a natural stone pattern. Although it was not possible to express a three-dimensional depth with a monotonous color tone sense, the stone-like plastic block according to the present invention has a three-dimensional marble pattern or a marble pattern with a three-dimensional depth by a method of combining various arbitrary shapes and sizes. It made it possible to obtain a granite pattern.
