[0002]

2. Description of the Related Art As shown in FIGS. 6 and 8, a conventional construction block having a pseudo-stone uneven surface on the surface side is a type in which a block A consisting only of a main body 10 is stretched when the inclination of a retaining wall is 30 degrees or less. 5, 6 and 7, the slope of the retaining wall is 30 to 8
In the case of 0 degrees, a type in which blocks B having a body 11 are stacked on the back of a main body 10 is known.

In FIGS. 7 and 8, reference numeral 12 denotes backfill concrete for fixing the block B, 13 denotes body concrete, 14 denotes backfill crushed stone, and 15 denotes foundation concrete.

[0004]

However, for example, as shown in FIGS. 5 and 6, since the main blocks A and B have a rectangular outer periphery, when these are arranged, a joining line C between the blocks is formed.
Is a straight line. When viewed from near, the rectangle of each block can be seen, and when viewed from a distance, the straight line of the joining line C can be clearly recognized.

In many cases, only a few types of the same stone pattern are produced due to the cost of the formwork, and the same stone pattern continues after construction. Nevertheless, the pattern becomes repetitive and artificial.

[0006] For example, Japanese Utility Model Publication No. 53-47761 discloses a cross-shaped building block, in which the position of the small connecting recess is determined by the position of the projecting end of the block.
It is an annular part that protrudes into the small recesses on both side edges.
The connecting means comprises a U-shaped connecting bracket and a bolt.
These parts are expensive and always require screw tightening.
There is a construction problem that it is necessary and troublesome .

[0007] Therefore, the present invention is the joining line between blocks becomes uneven lines, and unevenness of the body surface allows numerous combinations by also rotating construction in several patterns, moreover components are inexpensive, transportation Ya The purpose is to form a natural-style stone masonry retaining wall that facilitates assembly work.

[0008]

As shown in FIGS. 1A to 1E, an outer peripheral edge 1A of a concrete construction block body 1 is formed in a cross shape as shown in FIGS. The surface of the main body 1 is an uneven surface, and the four cross-shaped outer peripheral edges 1A are provided.
Small recess 2 is formed in each of the projecting end central place, these
A head 3A of a bolt connecting rod 3 is protruded at the center of each small concave portion 2, and the axial direction of the connecting rod 3 and the protruding direction of the protruding end portion.
Is the same as the one that was determined .

In the retaining wall construction state, a plurality of blocks
The main body 1 is juxtaposed so that its cross-shaped outer peripheral edges fit together.
Then , the heads 3A of the connecting rods 3 of the small recesses 2 facing each other in the lateral direction are fitted to the both end engaging portions 4A of the substantially U-shaped connecting piece 4.
The head 3A and the connecting piece 4 are embedded and fixed by a mortar 5.

[0010]

In the above-mentioned means for solving the problems, since the outer peripheral edge 1A of the main body 1 of each block D is formed in a cross shape, it is possible to construct while rotating these blocks, and the joining line between the blocks becomes a greatly concave and convex line. In addition, the blocks are firmly fitted in both up, down, left, and right directions, and the pseudo-stone uneven surface 1B can be rotated in one or several types of patterns to enable many combinations. Has a random pattern, and although it is an artificially manufactured block, a natural-style stone retaining wall can be formed.
