The present invention relates to a retaining wall block for use in constructing retaining walls, such as fillets, cutouts, and the like. More specifically, the present invention provides a retaining wall block, and more specifically, a stacking unit between blocks is stable and solid, and the supporting force of the block is good and heavy. The present invention relates to a retaining wall block having coupling means that can be easily constructed and constructed using large blocks to reduce construction period and cost.

In general, in the land, incisions, etc., a retaining wall that supports earth pressure on one side or prevents the collapse of the slope is constructed to withstand the earth pressure acting on the retaining wall.

Conventional retaining wall is formed by arranging reinforcing bars forming a frame of retaining wall on the fill surface or incision surface in a certain form, wrapping the reinforcing bar with formwork, and then casting concrete to cure the form to form the wall, and then the back of the wall. It was constructed by filling reinforcement soils containing soil, crushed stone, rubble, etc.

As described above, the reinforced concrete retaining wall constructed of reinforcing steel and concrete has a disadvantage in that the construction process is very complicated and the construction period is consumed a lot.

In order to solve various problems of the reinforced concrete retaining wall, the retaining wall block has been widely used in retaining wall construction in recent years. As the filling of rubble, the Korean Utility Model Registration Application No. 2005-18368 of the "retaining wall block including the connecting means" is disclosed and known.

In the retaining wall block 1 for constructing the retaining wall as shown in FIGS. 1 and 2, the front horizontal plate protrudes forward on the upper end of the plate-shaped rear vertical stand 21 and the rear vertical stand 21 ( 22) and a connecting clip (2) consisting of a pair of longitudinal vertical plates (23) protruding upward from both front sides of the front horizontal plate (22), the front of both sides of the retaining wall block (1) upper front In the rear, the first and second horizontal grooves 11 and 12 are formed to selectively insert the rear vertical stand 21, and the first and second horizontal grooves 11 and 12 are formed at both sides thereof. The horizontal plate 22 is formed with a longitudinal recessed groove 13 into which the horizontal plate 22 is recessed, and the connecting clip 2 fitted to the other retaining wall block 1 is formed at both front sides of the lower portion of the retaining wall block 1. The connecting groove 14 is formed so that a pair of longitudinal vertical plates 23 can be inserted therein.

Therefore, when the retaining wall is constructed, the retaining wall block 1 is first constructed on the ground in the transverse direction, and the first horizontal long groove 11 or the second horizontal long groove 12 formed on both sides of the upper front of the constructed retaining wall blocks 1 and the longitudinal line are vertically formed. The rear vertical stand 21 and the front horizontal plate 22 constituting the connecting clip 2 by inserting the rear vertical stand 21 and the front horizontal plate 22 of the connecting clip 2 into the direction recessed groove 13.

Projecting a pair of longitudinal vertical plate 23 provided in the upper portion, and between the retaining wall blocks (1) located in the lower portion of the retaining wall blocks (1) to be stacked to complete the retaining wall .

Here, when the multi-stage staircase retaining wall is constructed, the rear vertical stand 21 of the connecting clip 2 is inserted into the second horizontal long groove 12 and the first horizontal long groove 11 to construct the retaining wall. Between each retaining wall block 1, a grid 3 buried in soil is provided to improve the strength of the retaining wall after construction to prevent the retaining wall from falling down.

However, in order to build the retaining wall with the retaining wall block 1, the retaining wall block not only has to be separately provided, but the retaining wall block between the lower retaining wall blocks 1 is connected only with a pair of connecting clips 2. There was a problem that the strength of the retaining wall was insufficient, accompanied by cumbersome work of installing the grid 3.

In particular, as the connecting clip 2 is interposed between the upper and lower retaining wall blocks 1 as a connecting means, it is manually connected to the first horizontal groove 11 or the second horizontal groove 12 of the lower retaining wall block 1 when stacked. A skilled worker inserts the rear vertical stand 21 of (2) one by one, and lifts the retaining wall block 1, which is a large weight to be stacked on the top, with heavy equipment to connect the groove 14 for the connection of the retaining wall block 1. In order to insert the retaining wall block 1 into the pair of longitudinal vertical plates 23, the skilled worker must manually position the retaining wall block 1, thereby increasing labor costs in constructing the retaining wall and delaying the construction period. There was a problem.

The present invention has been made to solve the various problems caused by the conventional retaining wall construction, the object of the present invention is to provide the coupling means of the concave-convex structure integrally with the upper and lower parts of the block body, the stacking of the upper and lower blocks is stable To provide a retaining wall block having a fastening means that is strong and has a good bearing capacity.

The body 110 has a front central portion protruding forward and a first through-space portion 111 penetrating up and down in the center and a rear wall portion 114 formed on the rear surface, on one side of the body 110 Protruding portion 112, the groove portion 113 is formed on the other side, the protruding portion 112 is formed in a semi-circular shape having a length from the upper surface to the lower surface of the body 110 and integral with the body 110, the The groove 113 is integral with the body 110 in the shape of a semi-circular tube having a length from the upper surface to the lower surface of the body 110.

The side wall portions 120 and 120 ′ are integrally formed with the body 110 so as to extend rearward from both sides of the rear wall portion 114, which is the rear surface of the body 110, to be symmetrically paired with each other. The rear wall portion 130 is integrally formed with both side wall portions 120 and 120 'between the rear sides of the side wall portions 120 and 120' such that the rear wall portion 114 and the both side wall portions of the body 110 are formed. The second through space portion 111 'penetrating up and down by the 120, 120' and the rear wall portion 130 is formed.

The coupling protrusion 140 forms an inclined surface inclined from the front to the rear, and a plurality of right triangle coupling protrusions 140 of which the rear surface is vertical is the upper surface of both sidewall portions 120 and 120 'at the rear of the body 110.

The coupling recess 150 may be formed in the shape of a plurality of rectangular quadrangles.

Here, the number of the coupling protrusion 140 and the coupling recess 150 is selected as necessary.

That is, when only the vertical stacking without retaining the retaining wall block 100 in a stepped manner, the coupling protrusion 140 and the coupling recess 150 are formed in the same number, and the retaining wall block 100 is stacked in a stepped manner. In order to build the retaining wall, the number of coupling protrusions 140 is formed at least one less than the number of coupling recesses 150.

When the retaining wall block 100 is laterally built, the semi-circular protrusion 112 of the other retaining wall block 100 is inserted into the semi-circular tube-shaped groove 113 to be constructed. When the semi-circular projection portion 112 is inserted into the role of the retaining wall blocks 100 are firmly coupled to each other, and due to the rotatable coupling of the semi-circular tube-shaped groove portion 113 and the semi-circular projection portion 112 When it is necessary to construct the retaining wall block 100 on the top of the terrain, the retaining wall block 100 may be usefully constructed to bend by rotating the retaining wall blocks 100 little by little.

Next, the construction which builds a retaining wall with the retaining wall block provided with the coupling means of this invention comprised as mentioned above is demonstrated in detail.

First, a plurality of retaining wall blocks 100 are constructed in a transverse direction on a concrete foundation by inserting the semi-circular protrusions 112 of the other retaining wall blocks 100 into the semi-circular pipe grooves 113 of the retaining wall blocks 100.

Next, the retaining wall blocks 100 are alternately stacked on top of the retaining wall blocks 100 constructed in the transverse direction in the concrete foundation, which is shown in FIG. 4, which is a right coupling protrusion of the retaining wall blocks 100 located on the left side. The 140 is inserted into each of the lower left coupling recesses 150 of the retaining wall block 100 stacked on the upper side, and each of the left coupling protrusions 140 of the retaining wall block 100 positioned on the right is stacked on the upper side. The lower surface of the retaining wall block 100 is inserted into each of the right coupling recesses 150, and the protrusion 112 of the retaining wall block 100 adjacent to the groove portion 113 of the retaining wall block 100 is inserted in the transverse direction.

As such, the construction of the retaining wall is completed by repeating the stacking of the retaining wall block 100. When the retaining wall blocks 100 are constructed in the transverse direction on the first concrete foundation, the retaining wall block 100 is lifted by heavy equipment. The retaining wall block 100 is placed on the foundation and positioned so that the protrusion 112 of the adjacent retaining wall block 100 is inserted into the groove portion 113 of the retaining wall block 100 to the groove portion 113 of the retaining wall block 100. The protrusions 112 of the adjacent retaining wall block 100 may be inserted, and when the retaining wall block 100 is stacked on each upper layer, the retaining wall block 100 to be stacked is lifted with heavy equipment to lower the retaining wall block 100. Positioning so that the coupling groove 150 of the upper retaining wall block 100 is inserted into the coupling projection 140 of the insertion protrusion is laminated.

The reason why the coupling groove 150 of the other upper retaining wall block 100 can be inserted into and coupled to the coupling protrusion 140 at the time of stacking the retaining wall block 100 in each upper layer is as described above. Coupling protrusion 140 forms an inclined surface inclined from the front to the rear, and a plurality of right-angled triangular coupling protrusions 140 having a vertical rear face the upper surfaces of both sidewall portions 120 and 120 'at the rear of the body 110. It is formed in the shape of a tooth, the coupling groove 150 also forms a slope inclined to the rear to the front so that the coupling protrusion 140 is inserted, the coupling groove 150 of a plurality of right-angled triangular the back is vertical. Since it is formed along the lower surface of the side wall portions 120 and 120 'at the rear of the body 110, it is positioned on the lower retaining wall block 100 constructed by carrying the upper retaining wall block 100 with heavy equipment with tongs. Put it up and put it back a bit with heavy equipment Pushing the engaging projection 140 and the coupling groove 150 is coupled while pushing easily because of the inclined right triangle shape.

In addition, since the rear surface of the coupling protrusion 140 and the coupling groove 150 is formed as a vertical surface, even if the earth pressure is largely applied to the rear wall of the some retaining wall block 100, the vertical surface does not collapse because it is not pushed forward due to the vertical surface. Do not.

Although the present invention has been described by way of example as a case of constructing the stepped retaining wall shown in FIG. 5, the present invention is not limited thereto, and various modifications can be made without departing from the spirit of the invention.

Retaining wall block provided with a coupling means of the present invention, which acts as described above, has a stacking force between the upper and lower blocks by a combination of a plurality of coupling protrusions having a right triangle shape and a plurality of coupling grooves having a right triangle shape, and the support force of the block is stable. Not only this is good but there is an advantage that the retaining wall does not collapse even if the earth pressure is largely acted on the back surface.

In addition, the stacking of the upper and lower blocks does not require a separate connection means, it is possible to simply stack the blocks by combining the upper and lower coupling means formed integrally with the block by positioning and slightly pushing with heavy equipment, so that the construction of large blocks that are heavy Since it is easy, there is a special advantage that can significantly reduce the construction period and cost.
