With the development of heavy machinery and construction machinery, large blocks with good workability at construction sites have been used for river disaster recovery and road retaining wall construction. In the block molding process, cost problems such as soaring formwork prices due to the enlargement of formwork, increase in the cost of moving equipment such as hoist cranes in factories due to increase in product weight, and increase in transportation fare for finished products. Is coming.

Further, in the conventional block, the upper and lower blocks stacked as described above are provided with a through hollow portion through which a support member for preventing collapse is inserted. In a molding frame, this is formed by a core. Since it has a shape that must be molded, a high level of technology is required for drawing out the core after molding, and there has been a problem that the molded product is broken when the core is pulled out.

Further, various variations are required for the retaining wall to be constructed, and it is not possible to cope simply by stacking blocks of a single shape on one retaining wall.
For inclined retaining walls, etc., the length of the retaining wall changes according to the stacking, the block surface has an inclination angle to the retaining, the surface panel and the retaining panel are inclined in parallel, and the retaining wall surface and the retaining surface are inclined parallel by horizontal stacking It is becoming necessary to build blocks and the like.

If the conventional molding method is used, even if the basic shape is the same, but different lengths, different molds corresponding to the respective lengths are required. In addition, there is a problem that the cost is increased accordingly.

[0007]

SUMMARY OF THE INVENTION The present invention addresses the weight problem by dividing a block into a surface block and a stay block, and connecting the two blocks to one at the site or the like by a taper fitting structure. In addition, for a retaining block that requires a variety of retaining lengths even though the basic shape is the same, it is possible to adjust the retaining length by fitting it to the surface block and use the formwork at the molding stage It is.

Further, the basic shape of the unit block has a structure in which the front panel and the stay panel are connected by one or a plurality of support cylinders, and the front block and the stay block are detachably divided at a portion of the support cylinder. By changing only the block and changing the block, or changing the angle of the front panel and the stay panel with respect to the support cylinder, it is possible to meet various needs for the block.

Further, since the gap between the support cylinder connecting the front panel and the stay panel necessarily forms a hollow portion by the fitting connection of the front block and the stay block, the core molding which has a problem in drawing or the like is inevitable. The hollow part can be formed without performing, and it is also possible to adjust the length of the support cylinder in the forming mold of the retaining block, which can contribute to the efficient use of the forming mold. It is a thing.
