[Technical field to which the device belongs]

 The present invention is a block body for forming a corner block having a fracture surface as a decorative surface.

[0002]

[Prior art]

 The corner block 1 having the surface fracture surface 3 and the corner surface fracture surface 2 as shown in FIGS. 4 to 6 and an appropriate number of surface grooves 4 and corner surface grooves 5 is a decorative block having a feeling of natural stone. Has been prized. In order to manufacture such a block, a block block as shown in FIG. 7 in which a plurality of unit blocks are combined is made, and the block block is broken at the breaking portions aa and bb to form the corner block 1. . That is, FIG. 7 is a block block corresponding to a size in which four corner blocks 1 are juxtaposed, and a surface groove 4 is formed in the finished product at the break portion aa to prevent stray break lines. A through hole 6 for forming the corner groove 5 is also formed in the fractured portion b-b. Then, a deep groove 8 reaching the fractured portion bb is formed on the corner side at the fractured portion aa, and the deep end of the groove 8 is shaped so that the corner portion 9 is formed as it is. Has been. Such a block mass is first broken along the a-a part to form four unit blocks, and each unit block is broken along the b-b part to form a corner fracture surface.

[0003]

[Problems to be solved by the device]

 According to the above conventional breaking method, in the case of the example, first, the breaking is performed along the three breaking portions in the longitudinal direction of the unit block, and the corner surface of each divided unit block is broken respectively. Not only does the rupture process take time, but the rupture of the corner surface has a problem with stability at the rupture part due to its short dimensions. Has become. In addition, continuous production was not possible by connecting the concrete block block production line and the fracture line. The present invention provides a corner block forming body having a fracture surface capable of improving these points.

[0004]

[Means for Solving the Problems]

 The present invention is a block mass corresponding to a size in which a plurality of unit blocks of a desired size are juxtaposed, a break portion is provided at the boundary of each unit block, and a corner face equivalent portion of each unit block is further provided. Is a corner block forming body having a fractured surface, which is characterized in that a fractured portion capable of fractured at a time is provided.

In addition, through holes are provided at appropriate places of each fractured part in order to avoid straying of the fractured surface and to form a groove on the surface of the finished product. In the corner block forming body of the present invention, first, the corner-corresponding portions of the unit blocks are fractured at a time, and then the boundaries of the unit blocks are fractured to produce a corner block having a fracture surface with good yield. it can.

[Embodiment of device]

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an example of the embodiment, and the parts which are considered to be the same as those of the conventional product of FIG. 7 are designated by the same reference numerals. That is, it is a block block corresponding to a size in which four unit corner blocks 1 are juxtaposed, and has breaks aa at each boundary, and has through holes 6 at regular intervals on the line. is there. The through hole 6 has, for example, a hexagonal shape and is broken to form a gutter-shaped surface groove 4 (see FIGS. 4 and 5) on the fracture surface of the surface of the corner block 1 on both sides. What is different from FIG. 7 is that a fractured portion cc is provided in the corner portion instead of the fractured portion bb. That is, there is no groove 8 reaching the fractured portion c-c, and the through hole 6 is formed on the fractured portion c-c. Therefore, when the fracture is performed along the fractured portion c-c, the excess thickness portion 10 is fractured and removed all at once. After the breakage, the through hole 7 forms the corner groove 5 (see FIGS. 4 and 6), and the through hole 6 at the intersection of the breakage portion aa and the breakage portion c-c has the breakage corner portion 9 (See FIG. 4).

The corner block forming body of the present invention is sent by a belt conveyor 14 to a predetermined position of a cutting machine having an upper blade 11 and a lower blade 12 shown in FIG. Between the lower blade 12 and the lower blade 12 to break, and the excess thickness portion 10 is broken and removed. Then, the breaking portion aa is broken by the cutting machine shown in FIG. The reference numeral 13 in FIG. 3 indicates a side blade. This may of course be provided in the case of FIG. The above embodiment has been described by taking the example of taking four corner blocks, but the number can be increased or decreased as appropriate. Further, the hollow of the corner block may have any suitable size, shape and number and is not particularly limited. In addition, the shape of the through hole at the fractured part can be designed in various shapes.

[0008]

[Effect of device]

 The corner block forming body of the present invention is suitable for first removing the corner surface portion in a lump at a time, and then rupturing and separating it into the corner blocks of each unit. It is possible to manufacture a corner block having a fracture surface with a low fracture rate and a good yield. In addition, since the number of rupture steps can be reduced, continuous production can be achieved by connecting the concrete block block production line and the rupture line.
