Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for molding split blocks, and particularly to a new split block structure in which a large number of split blocks are mass-produced as a series.

In the past, this type of split block was made by polishing the circumferential side of the individually molded block to expose the split decorative surface on the surface, but...
In this method, it is necessary to mold each block individually, especially as a single unit, and a large number of molds, pouring processes, and post-moulding processes are required, which inevitably increases production costs. Moreover, it is necessary to grind each side peripheral surface of the molded block, and the crushing process requires a lot of effort.

Furthermore, in such conventional methods, the remaining parts of the shredded parts were naturally removed as waste materials, which resulted in wasted material and required a large amount of expense for disposal of the waste materials.

In the present invention, in order to reliably avoid the inconveniences in the conventional method of manufacturing split blocks, a large number of blocks are integrally connected and the connected blocks are broken and crushed. The gist of the invention is that blocks equivalent to a large number of blocks can be integrally manufactured by using the end face to be cut as the front and rear end faces of the blower, or either end face of loading the blower. During this curing, vibration is applied along the cutting groove in the demolding block, and the block is placed at the fractured point, and other methods suitable for this manufacturing method are used. is planned.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. (a) concrete is poured into a formwork in which a large number of blocks corresponding to ordinary blocks are arranged in series; This block body a is the front and rear end surfaces 1at1 during normal loading of the block 1.
b1, that is, in the present invention, it is integrally molded so as to be continuous only at the cutting surface, and during this molding, the cutting groove 2 is recessed in the outer circumferential surface of the block body a where cutting is planned. This is what I did.

The cutter blade is aligned with the groove 2 in the block body a constructed in this manner, and the block is pressed and crushed together with separately added vibration to construct an independent block 1, and the crushed end face is blocked. Loading front and rear end surfaces 1a of 1
, 1b, the shredded block 1 can be used as a decorative block.

Of course, when the above-mentioned crushing is performed in the vertical direction of the block body a, the front and rear end faces of the block body a as shown in Fig. 3 or 6, etc. 1 a,
It is actually possible to make the cutter cross obliquely to the block body a, and in this case, as shown in FIG. The direction of contact of the blade can be changed as necessary.

A typical block 1 produced using such a method does not have any loss in surface cosmetic characteristics, not only in the normal block shown in Fig. 4 but also in the special block shown in Fig. 5.
This allows a more natural-looking cut frame surface to be exposed on the loading block wall surface.

The block body a in FIG. 2 is provided with fitting means on the top, bottom, left and right sides of the block 1 for loading the block, and the block body 1 in FIG. As shown in Fig. 7, it has fitting means on the top, bottom, left and right sides as loading means for the preliminary block, and this is also natural in the normal block 1 shown in Figs. 1 and 4. However, fracturing at the top, bottom, left and right end faces, which are the loading joint surfaces, was completely avoided.

In addition, the illustrated example in FIG. 7 allows for the creation of a special shape as a block exterior material, as well as the creation of a tapered surface to prevent the infiltration of rainwater, and the provision of a cut edge 3 as necessary. This is what I did.

Due to the unique structure of the savior of the present invention, the number of split operations is reduced to half that of the conventional model, and pouring and curing can be done in one step as an integrated structure, and the formwork itself is integrated. This makes it possible to provide such a special split block at a low cost.

Furthermore, it is not necessary to create a formwork for a special block as shown in Fig. 5, and it is possible to use a casting formwork similar to a normal formwork, which facilitates pouring and retains residual moisture during curing. This makes it possible to provide split blocks of good quality.

Claims (1)

[Claims] 1. Concave groove-shaped cut edges 3 are integrally cast on both sides of the longitudinal symmetry axis of the upper and lower end surfaces of two blocks, with the end surface to be cut as one end surface of the front and rear end surfaces of the blocks. While shaping and curing, vibration is applied along the cut edge 3 of this cured and demolded block to press and crush it, and the fractured surface of one block is gradually tilted downward and outward. A split block characterized by a tapered surface.
