The present invention relates to a block connection structure for a concrete block interconnecting the concrete block in the lateral direction and the vertical direction, and more particularly, to improve the stability of the structure consisting of a plurality of concrete blocks and to facilitate the inclination and bending angle of the structure It relates to a block connection structure for concrete blocks that can be adjusted easily.

In general, concrete blocks for building slopes such as embankments, breakwaters, lakesides, roads, and residential lands are used to prevent falling and collapsing of soil and sand.

In addition, a technology for adjusting the inclination angle and the bending angle of the block structure by efficiently constructing the concrete block has been developed. As an example, it is registered as Patent No. 10-401173, which is from the front and the front surface where various patterns may be formed. The rear side has a trapezoidal shape inclined to the rear side, and the rear side is connected to the side toward the rear side, and includes a rear side having a protrusion on the left and right sides, and a through hole is formed in a plane corresponding to the side length, and is formed in the plane between the through hole and the front side. In the retaining wall block provided with a connecting portion for connecting the block of the upper layer, the connecting portion is formed in a guide groove which is formed in a predetermined depth in the bottom direction in one plane of the through hole, a plurality of spaced apart in the front direction from the guide groove formed through the bottom A seating hole for placing each block upstream and alternately stacking it, The fixing groove for guiding the h-shaped clip for fixing the block by holding the position of the block assembled between the guide groove and the seating hole has a predetermined depth formed from the upper surface.

In other words, the conventional block connection structure for concrete blocks can be easily constructed the structure of the concrete block formed by the inclination angle by adjusting the front and rear positions of the concrete blocks arranged at the bottom and the concrete blocks arranged at the top by using the clip of the lowercase h-shape. It can be.

However, the prior art as described above has a disadvantage in that the structure of the clip for adjusting the inclination angle can adjust only two inclination angles, so that it is not possible to construct the inclination angle structures of various angles, and cannot connect the concrete blocks arranged in the transverse direction. Therefore, the stability of the structure is disadvantageous.

Meanwhile, another example of the prior art has been registered as Utility Model Registration No. 20-214299, which is a hexahedron including two sides extending from the front, top, bottom, rear, and front to rear in the retaining wall construction block. An in-block body, wherein the block body is formed to extend in parallel with the front surface at a predetermined depth on the bottom surface to accommodate a head portion of an angle pin; a vertical room from the front side to the accommodation groove of the bottom surface It includes a pin hole penetrated in the direction and fitted with the insertion portion of the angle pin, a vertical hole vertically penetrated between the pin hole and the receiving groove and the rear, and comprises an angle pin connecting the block, the angle pin of the block Insertion portion having a plurality of side surfaces corresponding to the cross-section of the pinhole, is formed larger than the cross-sectional area of the pinhole, protruding distance from the insertion portion is formed different for each side, The head portion is accommodated in the receiving groove of the block.

This is an angle pin inserted into the pinhole can be adjusted in four stages of the block position of the upper and lower blocks can be variously adjusted inclination angle of the structure of the concrete block.

However, since the angle pin has a rectangular cross-sectional structure, the angle pin does not fit tightly in the lower receiving groove of the block into which the head of the angle pin is inserted. Therefore, the angle pin moves to the front of the concrete block due to the soil load of the constructed structure. There is a disadvantage that the structure is very poor stability of the structure.

And, as described above, the angle pins of the prior art also do not connect in the transverse direction of the concrete structure has a disadvantage that the structure of a plurality of concrete blocks are very vulnerable to the action in the transverse direction.

The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to connect the lateral direction of the concrete block, as well as to interconnect in the vertical direction stability of the structure constructed of a plurality of concrete blocks It is possible to easily build the structure of the concrete block having an inclination angle by easily adjusting the position of the upper and lower concrete blocks, and to provide a block connection structure for the concrete block that can easily adjust the bending angle of the transverse concrete block There is.
