Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block forming form device capable of forming a concavo-convex pattern such as a pseudo-stone pattern on a front surface (a back surface if necessary) of a concrete block.

[0002]

2. Description of the Related Art A conventional formwork for forming an uneven pattern such as a pseudo-stone pattern, a rhombus, or a geometric pattern on the front surface of a concrete block enables moldability, that is, enables demolding. ), It was necessary to provide a concave and convex pattern in front of or behind (actually above or below) the direction in which the mold was removed (removed). As a result, the shape of the concrete block that can be formed is restricted, and the production efficiency is reduced. In addition, in the case of a structure that forms a cavity in the vertical direction, such as a stacking block, it is a quick removal type with good production efficiency (a type that removes before the concrete solidifies after molding), and it has an uneven pattern such as a pseudo stone pattern It has been considered impossible to provide a structure having a through-hole on the front or back surface.

[0003]

As a solution to the above-mentioned drawbacks of the prior art, a pseudo-stone pattern made of a wax-like or thermoplastic fixing material is formed at the bottom of a mold, and cement is filled thereon. There is also a casting method of solidification (e.g., JP-A-03-205103, JP-A-03-203944, etc.), but there is a molding preparation stage, and operations such as removal of a waxy substance or a thermoplastic substance after concrete solidification. It was complicated and the production efficiency of concrete blocks was poor. When a concrete block product having a pseudo stone pattern on the front surface and having a through hole is immediately molded out by demolding, the stone pattern and the through hole are hard to be particularly uniform in ordinary vibration and pressure molding,
Also, if filling is emphasized and molded to be homogeneous, it is very difficult to obtain dimensional accuracy of the product height and width, and it is generally inefficient, so it is difficult to mass-produce and it is compatible with the casting method .

[0004] The present inventors can form an uneven pattern such as a pseudo-stone pattern and a through-hole on the front surface of a concrete block (or also on the back surface if necessary) without requiring complicated work by hand. We studied to develop a concrete block forming machine with high production efficiency.

[0005]

As a result of examining the above-mentioned problems, at least a front plate is formed on a concrete block with a concave-convex pattern in a molding form including a front plate, a back plate, both side plates and a vertical pressing plate. A concrete block forming die apparatus characterized in that a forming die to be applied is provided, and forward and backward means for moving the front plate in the front-rear direction beyond a distance at which the concrete block can be removed is provided.

In addition, a through hole for inserting a punching die is provided in the front plate or the rear plate, and the punching die can be moved forward and backward in the through hole for inserting the punching die. It is. The holes formed in the concrete block by the punching die are used for drainage holes, windows of fish reef blocks, and the like.

FIG.
FIG. 2 is a perspective view of a concrete block formed by the apparatus of the present invention.

The concrete block forming formwork apparatus of the present invention is not limited to the illustrated apparatus, but includes a front side plate 1, a back side plate 2, and peripheral side plates including both side plates 3, and a vertical pressing plate 4 And a bottom mold 5 and a core 6 serving as a cavity of a concrete block (hereinafter abbreviated as block). Although not shown, the side plates 3 on both sides
There is an inward convex portion that gives irregularities to the block side surface. In addition, product raising / lowering means to obtain block products by immediate demolding
A (product raising / lowering elevator (push-up cylinder)) 7 is provided so as to vertically move up and down from the bottom plate 5.

In addition to the above-mentioned structure, the front plate 1 is used as a molding surface 1a of the pattern for imparting a concavo-convex pattern to the block of the molded body, and the front plate 1 is moved in the front-rear direction by a distance capable of removing the block. A movable cylinder of the reciprocating means 8 is provided. Thereby, at the time of molding, the work can be advanced to perform a tightening operation for completely imparting an uneven pattern to the front surface of the block.
Also, when removing the block product immediately, the front plate 1
(To the left).

The front plate 1 and the rear plate 2 are provided with through holes 9, 10 for punching die insertion so that the punching die 11, 12 can advance and retreat in the front and rear directions in the through holes 9, 10 for punching die insertion. In addition, through holes 13 and 14 are provided on the front and back surfaces of the molded body block 15 (see FIG. 5).

Hereinafter, FIG.
The details of the production of the environmental protection type pseudo-stone pattern block shown in FIG. As shown in FIG. 1, the molding plates around the front plate 1, the rear plate 2, and the side plates 3 on both sides are placed on the upper portion of the bottom plate 5, and the blanking dies provided on the front plate 1 and the rear plate 2 are inserted. The punching dies 11 and 12 are inserted from the through holes 9 and 10 for use.
A molding chamber formed between the core 6 standing on the bottom plate 5 and the surrounding molding plate while vibrating the entire formwork in this state.
The concrete material 17 is filled into the inside 16.

Next, when the filling of the concrete material 17 is completed, as shown in FIG. 2, the vertical pressing plate 4 is lowered, and the front plate 1 is pressed by the cylinder of the advance / retreat means 8 so that the concrete material 17 spreads all over. The material is faithfully in contact with the molding surface 1a so that the molding is completed and the molding can be performed smoothly. After that, it is pressurized by the vertical pressing plate 4 in a vibrating state,
It is compacted by shaking.

After the molding, as shown in FIG. 3, first, the dies 11, 12 are extracted. At this time, the front plate 1, the back plate 2, and the vertical pressing plate 4 are kept in a pressurized state. Pulling out in this state improves the appearance of the through-hole provided to the block and eliminates deformation.

When the product is released from the mold, as shown in FIG. 4, the upper pressurizing cylinder releases the pressurization, and the vertical press plate 4 is placed on the compact block 15 and the upper press cylinder is moved upward. The front plate 1 is retracted as far as possible (or downward). Thereafter, the product is released from the product by means of a product elevating means (push-up cylinder) 7. The demolded product block moves to the curing and solidifying place, and the block forming mold apparatus is again in a state of waiting for the next forming. Since it is an immediate demolding type, the production efficiency is higher than that of the above-described casting method.

[0015]

According to the present invention, a concrete block forming and forming apparatus for forming concrete blocks on a front surface or a back surface of a concrete block having an uneven pattern such as a pseudo-stone pattern, a rhombus or a geometric pattern (through holes as necessary) is formed. Can be manufactured by demolding. That is, it is possible to manufacture a concrete block having a pseudo-stone uneven pattern or the like on the outer surface (surface) with high efficiency with almost no need for manual operation. In addition, a large number of concrete products can be manufactured in a short time using the same mold without requiring a large number of molds.
The production efficiency is better than the casting method, and there is no unevenness in the product.
