The present invention relates to a retaining wall reinforcing fixing means, and a rear wall of the reinforcing bar wraps around the perimeter of the buried block, and relates to a retaining wall reinforcing fixing means capable of increasing the reinforcing strength of the block in which the front of the reinforcing bar is fixed.

In general, a retaining wall refers to a wall made to prevent the slopes generated by stacking or shaving soil from collapse due to the pressure of the soil.

Therefore, generally known retaining wall is a wall retaining wall using a retaining wall block and reinforced concrete, which is constructed by stacking a plurality of blocks to be installed in front of the slope to prevent collapse of the slope, as described above.

Accordingly, the present invention is an improvement of the retaining wall block of the retaining wall, which will be described below.

That is, Figure 9 is a perspective view showing an embodiment of a conventional reinforcement fixing means.

A conventional retaining wall block (hereinafter referred to as a "retaining wall") includes a retaining wall stacked in a plurality of blocks 1 at a distance in front of the slope and soils filled between the rear of the retaining wall and the slope. do.

And each of the blocks (1) is further provided with reinforcing fixing means (2) which is embedded in the earth and sand to securely maintain the stacked state of each block (1).

That is, the conventional reinforcement fixing means 2 is integral with the reinforcement bar 21 and the rear side of the reinforcement bar 21 which the front side is fixed to the upper part of each block 1, protrudes to the rear, and is embedded in the earth and sand. It is provided with a concrete block 4 is embedded in the soil.

Therefore, in the construction of the retaining wall, by laying the concrete block fixed to the rear of the reinforcement bar fixed to the upper part of each block and the concrete block integrally fixed to the rear side of the reinforcement bar, the stacking state of each block can be maintained firmly. .

However, the concrete block fixed integrally to the rear side of the reinforcement bar is a weight body, when constructing the reinforcement bar to which the concrete block is integrally fixed to the rear of each block, there is a problem that the workability is reduced.

In the related art, a prefabricated reinforcing fixing means for assembling a concrete block is known to solve the above problems.

That is, Figure 10 is a perspective view showing another embodiment of the conventional reinforcing fixing means, according to Republic of Korea Patent Publication No. 43815, the retaining wall is bent in one side to the front is inserted into the groove 11 formed on the upper portion of the block (1) And a reinforcement bar 21 having a rear portion protruding to the rear of the block 1 and having an end portion bent, and having a rear side of the reinforcement bar 21 inserted therein. Insertion hole 22 is provided with a buried block 22 including a recessed groove 226 formed by recessing one side of the bent portion 216 of the reinforcement bar 21 in the lower portion of the recessed groove 226 is inserted. 227 is further provided.

Therefore, through the investment block to secure the rear of the reinforcement bar and the reinforcement bar to prevent the separation and distortion of the block, as well as to facilitate the reinforcement bar to be embedded in the investment block.

However, due to the recessed groove into which the rear side of the reinforcing bar is inserted, the thickness of the investment block capable of supporting the rear of the reinforcing bar becomes thin. Therefore, the reinforcement strength of the investment block for supporting the reinforcement bar is weakened, so that the load due to the pressure of the earth and sand is transferred to the reinforcement bar as time passes, so that the investment block is damaged.

The present invention has been invented to solve the above problems, the rear of the reinforcement bar is wrapped around the perimeter of the buried block to retain the retaining wall reinforcement fixing means for increasing the reinforcement strength for the block is fixed to the front of the reinforcement bar The purpose is to provide.

In addition, the rear of the reinforcing bar is inserted into the vertical through-hole of the buried block, there is also an object to provide a retaining wall reinforcement fixing means that can increase the reinforcement strength for the block is fixed to the front of the reinforcing bar.

In addition, it is another object of the present invention to provide a retaining wall reinforcing fixing means capable of quickly constructing a retaining wall by easily installing a reinforcing bar around the investment block.
