Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing large decorative concrete blocks as so-called artificial stones.

Currently, large decorative concrete blocks with reinforcing bars called artificial stones are not manufactured.

So-called artificial stones are made by polishing the surface with a whetstone after drying concrete made using decorative pebbles such as Nazi black stone, canary stone, and soapstone, but they are thin in thickness. For example, in a building, it is used by hanging it from the wall below. Also, when used as a road paving material, it is easily applied to the underlying foundation layer. This type of artificial stone is only for show, and its strength is completely weak. Therefore, the original properties of concrete are not used.

Gravestones that can be called artificial stones are made by applying a thin layer of decorative concrete to ordinary concrete that serves as the inside, and then polishing the surface after it dries; this gives it weight and durability. Since no consideration is given to t, b, and strength, the original characteristics of concrete are not utilized to a great extent.

The current mainstream method for making mansion walls is to combine small blocks vertically and horizontally and coat the vertical surfaces, but this is not very impressive in Japan, where there are many earthquakes, as it is easy to collapse.

There are two reasons why people don't build concrete walls even though they know it's a good idea. 7. The cost increases rapidly due to the use of formwork, and in order to overcoat the first layer of decorative concrete over the normal concrete layer, the formwork must be removed after the normal concrete layer has dried, and then the formwork must be removed. There are 97 reasons why it is not possible to integrate the two layers in this way, rather than having to do the double work of pouring the decorative concrete layer by setting up the formwork with a gap open. .

Still, decorative concrete walls are very good for bathrooms, even in wooden houses, but are not currently used for the same reasons mentioned above.

A single-layer concrete wall using decorative stones can be built using formwork as before, but the cost of using formwork increases rapidly, far exceeding the cost of using decorative stones. This results in high costs. Furthermore, even if they were made in this way, polishing them on-site would be a nuisance to the neighborhood and would be unimpressive.

For these reasons, decorative concrete walls are durable, beautiful, and impermeable to moisture.
Although it has a certain rhythm, it has never been actually used.

In the present invention, a base concrete is constructed by erecting a rectangular frame plate on a horizontal or almost horizontal smooth surface and pouring concrete using inexpensive pebbles into the frame plate.

When laying the cleat layer, some reinforcing bars that come out of the frame board are included in the base concrete layer 1.
The feature is that before the surface of the base concrete layer is dry, concrete using 7JX stone for decorative stones is passed over the bare surface, a decorative concrete layer is overlaid, and after drying, the bare surface of the decorative concrete layer is polished. The purpose of the present invention is to open the door to the use of wall materials with all of the three excellent properties mentioned above, by providing the easy manufacturing of large decorative concrete blocks for wall materials.

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

As shown in Figure 77, a flat plate, e.g. an iron plate, is placed horizontally or close to horizontally on a stand/table, supported in a prefabricated manner or by an automated arm as shown in the figure, and shaped into a rectangular shape, e.g. υ Place the iron plate formwork 3 on the iron plate. Stand Z made of concrete, 191. Line them up and place them in the frame, rebar Yu, Yu 901. A hole made in one piece of the formwork: 1. Insert it from the stand, go to the stand, go to 201. It is best to place concrete on top of the concrete in advance and then pour concrete IJ - using pebbles of grade 9 to form the base concrete layer A.

These reinforcing bars are attached to the base concrete layer A as shown in the Oλ diagram.
Set the height of the stand and hole so that it is in the center of the hole.

Before the base concrete layer A dries, especially before its surface area dries, after about 20 to 30 minutes according to experience, pour concrete using decorative stones on the surface of the base concrete layer A. . You can pour it in a certain amount and press it with an iron plate descending from above to make it smooth and smooth, but you can also spread it out and apply it as you would for plastering. This is a two-layer mX/Jm standard product, so it is sufficient to apply it by hand. Machine coating) is of course possible. At an appropriate time, remove the formwork 3, allow it to dry thoroughly, and then polish it with a whetstone to create a beautiful mirror-like surface. Basal layer! Decorative concrete layer B overlaid on Q is completely integrated with the lower layer, so both layers will not peel off.

Various patterns can be written on the top layer of concrete when it is poured, coated, or pressed. If you want to create a pattern with decorative stones, first pour concrete for the first surface layer to make the surface flat, then drop the stones arranged upwards on the pattern hole and drop them into the coating layer. It is a good idea to press it again. Wall materials with such patterns and drawings are used in bathrooms and are extremely inexpensive compared to conventional tiles.

As shown in FIG. 3, it is easily possible to make a comb hole 7 in advance. This is built in the bathroom/side wall sump. In addition, a window hole, a hole for operating gas appliances, a hole for electrical wiring, a hole for water pipes, etc. are also provided in advance.

For reference, the construction method for the fence is shown in the diagram. Dig a trench,
Spread gravel, place stands 9 here and there, bend the protruding reinforcing bars 000 degrees, and place the wall block on stand 2 to stand it up. If concrete is poured into the +4, ideal construction will be possible than shown in the Ota diagram. This work is the same for bathrooms.

The wall block according to the present invention has reinforcing bars, layers A and B.
Since it is integrated, it is durable and mirror polished.
The second thing is the clean feet, and the second and third thing is that the mirror surface has a long-lasting quality.In other words, it has excellent durability and has excellent characteristics such as triple beats and double beats. The cost of manufacturing and construction is extremely low, so it has extremely high practical value when used for fences and bathrooms.

Claims (1)

[Claims] A base concrete layer is created by erecting a rectangular frame board on a horizontal or nearly horizontal smooth surface and pouring concrete using cheap pebbles into it. Real reinforcing bars are included in the base concrete layer, and before the surface of the base concrete layer dries, concrete using pebbles for decorative stones is poured onto the surface and a decorative concrete layer is layered. Manufacture of large decorative concrete blocks for wall materials, characterized by polishing the surface of the decorative concrete layer after drying.
