In the first to third embodiments described above, in the retaining wall block fixing device comprising a horizontal bar 1 and a vertical bar 2, a connecting means 3 connecting the horizontal bar and a vertical bar, and a fixing part 4, The fixing part 4 is shown in the figure as being fixedly connected to the vertical bar (2). However, since the position of the fixing part may change depending on the situation on the ground, it may be difficult to install the fixing part when the vertical bar is connected to the fixing part.

Accordingly, the fourth embodiment of the present invention proposes a structure in which the vertical bar is easily connected to the fixed portion.

As shown in Fig. 4A, in the structure of the horizontal bar and the vertical bar, the connecting means, and the fixing part of the second embodiment, the modified groove 4'11 and the horizontal groove 4'12 are formed on the surface of the fixing part 4; A groove formed in the shape of a " T " is formed, and a male thread 2'1 is formed on an outer surface of the end of the vertical bar 2, that is, the end connected to the fixed portion. By connecting the longitudinal bar 2 to a "T" shaped fixture 6 consisting of an upright portion 6'1 and a horizontal portion 6'2, corresponding to a "T" shaped groove formed in the surface of the The vertical bar is connected to the fixing part. An internal thread 6'11 corresponding to the male thread 2'1 is formed inside the upright portion 6'1 of the fixture 6 to be screwed with the male thread.

Then, when the "T" shaped fixing part is inserted into the groove 4'1 of the fixing part, the horizontal part 6'2 of the fixing tool has the horizontal groove 4'12 of the groove 4'1. The upright portion 6'1 is inserted into the vertical groove 4'11. Therefore, since the contact area between the horizontal portion and the horizontal groove is widened, even if a large force is generated from the retaining wall to the vertical bar and the horizontal bar connected through the connecting means, the fixing part supports the horizontal bar through the vertical bar and ultimately used in the example of the retaining wall. Horizontal bar and vertical bar may be expensive because it is made of metal such as iron and also uses connecting means for connecting horizontal bar and vertical bar, and it is necessary to form tabs and spirals for connecting horizontal bar and vertical bar to connecting means. This requires pre-machining work.

Accordingly, the fifth embodiment of the present invention proposes a block fixing device that does not use separate horizontal bars, vertical bars, and connecting means.

Figure 4b shows a block fixing device of a fifth embodiment according to the present invention.

As shown in FIG. 4B, the block fixing device according to the fifth embodiment is inserted into the horizontal bar 1 and the vertical groove 52 inserted into the horizontal groove 51 of the block, similarly to the first to fourth embodiments. It consists only of the wire means 7 and the fixing part 4 which fixes the wire means in the ground.

Circular first and second ring portions 7'1 and 7'2 are formed at both ends of the wire means. And the fixing part 4 is formed with the groove | channel 4'1 of "T" shape similarly to 4th Embodiment. The connection of the wire means to the fixing part is made by a connecting rod 8 inserted into the horizontal groove 4'12 of the groove 4'1. The installation method of the fifth embodiment configured as described above will be briefly described as follows.

First, one of the first and second ring portions 7'1 and 7'2 of the wire means 7 is inserted into the horizontal bar 1 to connect the wire means to the horizontal bar, and the horizontal bar is positioned in the horizontal groove of the block. Let's do it. Then, the wire means is inserted into the longitudinal groove (52). Then, the other ring portion of the wire means is inserted into the connecting rod 8 to connect the wire means and the connecting rod, and the connecting rod is positioned in the horizontal groove 4'12 of the groove 4'1. The wire is then placed in the vertical groove 4'11 of the groove. Accordingly, the horizontal bar 1, which is subjected to the force by the retaining wall, is supported by the fixing part connected to the horizontal bar through the wire means.

The wire means may consist of a single metal wire or wire rope.

In this way, since only the wire means 7 made of a single metal wire or a wire rope having a ring portion for connection at both ends is used, the construction means 3 is not used in the first to fourth embodiments. In addition, the construction process is simplified and the retaining wall construction efficiency is improved.

On the other hand, it is shown in Figure 4b to use one wire means in one block and one fixing portion, it is also possible to use two wire means in the two blocks and one fixing if necessary. In other words, since the two wires are connected to one fixing portion, they form a "V" shape at the time of installation. However, even in this case, the method according to the fifth embodiment of the present invention is used.
