Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for molding a sliding area block.

Conventionally, the method for forming blocks for civil engineering is as follows: (1) Two layers of mortar, which will become the smooth surface part, and rough concrete I/material, which will become the body part, will be combined and molded, and the formwork will be inverted. (2) a so-called reversal method in which a receiving plate with a solid product shape is inserted into the formwork, and the product is removed upwards after filling with material and molding; (3) There is a so-called bottom-pull method in which a mold having a structure in which one or several products are formed is placed on a smooth receiving plate, and after filling the mold with material, the products are removed upward.

Among them, method (1) requires a complicated process and a large number of workers, and the average production volume per person per molding machine is about 150 to 200 pieces, which is inefficient. Since the composition of the concrete materials of the surface layer and the body are different, this method has the drawback that they tend to peel off from each other and weather after installation, but this method is currently widely used.

Method (2) has many disadvantages in labor-saving automation because the product is pushed up to the top of the mold to remove the mold after molding, and the density cannot be increased too much because the product inside the mold is pushed up. Moreover, since the sides are rough, it is not possible to make a product that is waterproof and has sufficient strength.

Method (3) involves placing the formwork on a smooth receiving plate, passing the core through the top and bottom, filling the space between the formwork and the concrete material, and forming the mold, which is subject to large vibrations. Although material feeding time can be shortened and products with high dimensions can be obtained, the side surface in contact with the formwork becomes a rough surface and the surface of the product lacks practicality, so it is not adopted even if it saves labor. There wasn't.

The present invention is a block molding method and a molding device that take advantage of the advantages of the above-mentioned undercutting method and eliminate the drawbacks. In addition, the partition plate is vibrated up and down in a different way from the formwork to obtain a product with a realistic surface.

Embodiments will be explained with reference to the drawings. FIG. 1 is a plan view of the device according to the present invention, and FIG. 2 is a front view thereof, in which 1 is an outer frame, which has a partition plate 2 in the center, Both upper ends of the partition plate 2 are attached to mounting seats 4 of the outer frame 1 via elastic bodies 3.

An inner frame 5.degree. 5 is provided in each empty space partitioned by a partition plate 2 in the outer frame 1.

A vibrating body 6 is attached to the outside of the outer frame 1.

This is an eccentric weight that is rotated by pulleys γ and 7 to give slight vibrations to the outer frame 1 and the inner mold frames 5 and 5.

To make a block using such a device, the inner formwork 5,
Concrete material is put into the inner formwork 5.5, the vibrating body 6 is rotated by a pull leaf, and pressing plates 8, 8 are pressed down from above while applying slight vibrations, and the concrete material in the inner formwork 5.5 is tightly formed. do.

At this time, since the partition plate 2 makes its own vibration due to the elastic body 3, the concrete material and the partition plate 2 are connected to each other at the sliding surfaces 9, 9 where the concrete material in the inner formworks 5, 5 comes into contact with the partition plate 2. As the sliding occurs, the paste in the concrete material oozes out onto the surface, and the partition plate slides it into the concrete material surface, so the sliding surfaces 9, 9 become beautiful sliding surfaces. .

Then, the molded body is pulled out downward, and a product as shown in FIG. 3 is taken out on the opposite side.

The sliding surface of this product is beautiful and has high commercial value, and as the surface layer hardens, it has the effect of preventing water absorption and preventing surface weathering.

In addition, unlike sliding surface blocks, there is less light reflection from automobile headlights, etc., and it is effective when used for residential land development.
