<Configuration>

As shown in FIGS. 2 and 3, the wall retaining wall having a reinforced load resistance according to a preferred embodiment of the present invention, the wall 100, the wall 200 built up to support one surface of the wall 100, and the wall (100) and the bottom wall 300 is buried in the ground to fix the wall 200, and comprises a fastening means 400 for coupling the wall 200 and the bottom 300. Here, since the wall 100, the beam wall 200, and the floor 300 are components of a general retaining wall, the description thereof will be simplified.

First, the wall 100 is a member in close contact with and supports the inclined surface. The wall 100 is erected from the ground, and for this purpose, a lower side portion may be inserted into and installed in the insertion groove 310 processed in the bottom body 300.

Further, the beam wall 200 is a member that supports the wall 100. The complementary wall 200 is a substantially right triangle on the side, and is fixed to intersect one surface of the wall 100 so that the lower part is fixed to the floor 300 to support the wall 100 based on the floor 300 Can be installed. In addition, the lower height of the beam wall 200 may be positioned higher than the lower height of the beam wall 100 in FIG. 3. This is to secure the installation space of the fastening means 400 for the coupling between the wall 200 and the bottom 300. In addition, the retaining wall 200 may be maintained in a standing state before pouring through the fastening means 400 described below.

In addition, the bottom body 300 is a member to which the wall 100 and the beam wall 200 are fixed. The bottom body 300 has a predetermined area on a plane, and may be installed to be embedded in the ground. In addition, the bottom body 300 may include an insertion groove 310 processed to insert a bottom side portion of the wall 100. Therefore, the lower side of the wall 100 is inserted into the insertion groove 310, so that the wall 100 can be installed in a granular shape with respect to the floor 300. In addition, the bottom body 300 may include a receiving groove 320 for accommodating the fastening means 400 described below. Here, the insertion groove 310 and the receiving groove 320 may be created after cement placement. At this time, the bottom body 300 may be a material commonly used, such as non-constriction mortar, in addition to cement.

In addition, the fastening means 400 is a member that fastens the lower portion of the beam wall 200 and the upper portion of the bottom body 300. As an example, the fastening means 400 may include a support plate 410 and a fastener 420 as shown in FIGS. 3 to 5.

The support plate 410 is a member disposed between the beam wall 200 and the floor body 300. The support plate 410 has a plate-shaped steel material at regular intervals in which the yaw and iron parts are continuous, and the apex and the apex of the iron part have a certain length while the yaw part and the iron part are separated. It can be manufactured by slanting. In addition, the size of the support plate 410 may be the same as or similar to the width of the lower surface of the wall 200, and may be the same as or similar to the length on the side of the wall 200. At this time, the support plate 410 may be made of one on the side, or may be made of two or more and continuously disposed. The shape of the support plate 410 is distributed to the entire support plate 410 along the inclined portion and the support plate 410 installation portion of the bottom body 300 along the inclined portion when a load is applied upward or downward on the recess or iron portion, Through this, the resistance of the load can be increased. In addition, since the support plate 410 is disposed to support the lower surface of the beam wall 200, the beam wall 200 may be assisted to maintain a standing state in its own state in a fastened state with the fastener 420.

The fastener 420 may include a first fastener 430 and a second fastener 440 that are fastened to the main and iron parts of the support plate 410. Of course, the first fastener 430 or the second fastener 440 may be provided alone and installed.

Here, the anchor 441 may be a conventional anchor shape including a straight line shape or a "J" shape on the side.

On the other hand, as another example, the support plate 410, as shown in Figure 6, the main portion and the iron portion may be manufactured in a substantially wave-shaped square wave shape. The shape of the support plate 410 may be the most efficient shape to ensure that the load resistance is maximized by making the most effective contact with the reinforcement bar. To utilize this, the support plate 410 may be arranged to contact the reinforcing bars 330 to increase the load resistance. At this time, the square wave-shaped support plate 410 may support the beam wall 200 by standing on the reinforcing bar 330. For this reason, the next process may be performed after the wall 100 and the beam wall 200 are erected on the floor 300 without being fixed with separate equipment.

In addition, the reinforcing bar 330 may be reinforced on the upper and lower sides of the bottom body 300. In more detail, the lower reinforcing bar 330 is positioned below the main portion of the supporting plate 410 so that the supporting plate 410 can be placed on the lower reinforcing bar 330. In addition, the upper reinforcing bar may be installed to be located below the iron portion of the support plate 410 to fit. In addition, the lower reinforcing bar 330 may be installed to be installed and fitted on a recessed portion of the support plate 410, and the upper reinforcing bar 330 may be installed to be positioned below and fitted to the iron portion of the support plate 410. At this time, the support plate 410, the second fastener 440 may be fastened to the recessed portion, the first fastener 430 may be selectively fastened to the iron portion. Therefore, when the beam wall 200 is moved in a direction to support the wall 100, the fastening force and the load resistance between the beam wall 200 and the floor body 300, the support plate 410, as well as the reinforcing bar 330 It can be interlocked and raised.

On the other hand, the fastening means 400 is another example, as shown in Figure 7 (a), the support plate 410 is flat, the apex of the iron part is made inclined between the iron part and the recess, and the iron part and / or yaw Slot-shaped through-holes 411 may be processed at the apex of the region. In addition, the third fastener 450 may be fabricated such that the locking piece 451 is fixed in the form of a wing to the lower side of the anchor 441 protruding downward by being partially embedded in the lower side of the wall 200. . At this time, the engaging piece 451 may be installed protruding sideways in more than one direction, preferably in both directions, around the anchor 441. Also, the anchor 441 may be a straight shape or a "J" shape. And the length of the through hole 411 is shorter than the length of the engaging piece 451, which is to allow the engaging piece 451 to be refracted while passing through the through hole 411.

Thus, as shown in Figure 7 (b), when the wall 200 is seated on the bottom body 300, the anchor 441 and the engaging piece 451 moves downward to pass through the hole 411 while the engaging piece Both sides of the 451 may be bent upward. At this time, the anchor 441 and the engaging piece 451 may be integrally manufactured, or the anchor piece 453 may be fixed to the anchor 441 to be manufactured. Both sides of the hook piece 451 refracted in this way, when the wall 200 is moved in a direction to support the wall 100, especially when the wall 200 is rocked upward, it is in contact with the poured cement, Finally, by being in contact with the reinforcing bar 330, it can be interlocked with the support plate 410 to increase the fastening force and load resistance between the beam wall 200 and the bottom body 300.

On the other hand, as a modified example of FIG. 7, the fastening means 400 are the reinforcing bars 330 in which the third fastener 450 is reinforced while the support plate 410 is excluded, as shown in FIGS. 8(a) and 8(b). It may be manufactured such that both sides of the engaging piece 451 bend upward while passing between them. At this time, the length between the reinforcing bars 330 in which the length of the engaging piece 451 is reinforced may be longer. Therefore, when both sides of the engaging piece 451 are moved in the direction in which the wall 200 is supporting the wall 100, especially when the wall 200 is rocked upward, it is in contact with the poured cement, and finally By being in contact with the reinforcing bar 330, the fastening force and load resistance between the beam wall 200 and the bottom body 300 may be increased by being interlocked with the support plate 410.

In addition, the third fastener 450 may be buried after the support plate 410 is excluded and received in the receiving groove 320 in place of the first fastener 430 and/or the second fastener 440. .
