The present invention relates to a prefabricated retaining wall block used in the construction of retaining walls for protecting land, cutouts, and the like, and more particularly, to a side binding block for closing the side surfaces of prefabricated retaining wall blocks that are fitted together.

In general, the retaining wall block is to prevent the collapse of the soil due to the loss of soil in the filly land or incision. In the conventional construction, the retaining wall block combines the block and the block by means of a separate binding means and a brick block having a jaw formed at the rear end As the construction time increases according to the construction area of the retaining wall, the construction of the fast and solid retaining wall is inevitably limited, and the binding is weakened and partially collapsed by the earth pressure applied to the built retaining wall.

In order to solve this problem, a prefabricated retaining wall block has been proposed to be fitted to each other, the present invention is specifically to provide a side binding block for the side finish of the prefabricated retaining wall block.

As a way to improve this problem, the Utility Model Registration No. 20-0194534 'prefabricated retaining wall block' by the present applicant has been proposed. However, as shown in FIG. 8, although the prefabricated retaining wall block has a form in which the binding block 30 is coupled to the support block 20, the groove formed in the binding block 30 is formed in the support block 20. Since the binding block 30 and the support block 20 are not firmly fixed, the binding block 30 slides along the binding block 30 even when the binding block 30 is coupled to the support block 20. I had a problem.

In addition, the gap between the binding blocks 30 has a structure that combines a separate second reinforcing block 50 to fill the gap, the assembly process is somewhat complicated, the assembled structure is not robust problem I had.

It is an object of the present invention to provide a side binding block for closing the filling material inside the prefabricated retaining wall block so as not to flow through the side.

It is an object of the present invention to provide a prefabricated retaining wall block coupled to each other without a separate fastening means.

The present invention for achieving this object has a vertically symmetrical shape, the support block having a coupling hole in the upper end and the lower end; and, having a vertical symmetry, having a width larger than the coupling hole and the support in the front and rear A coupling groove having a shape corresponding to an upper end and a lower end of the block, and a width of the portion in which the coupling groove is formed is a binding block formed to correspond to the width of the coupling hole; and a coupling groove identical to the binding block. It provides a prefabricated retaining wall block including a side binding block, characterized in that it comprises an extension between the coupling grooves.

The side binding block is provided with a drain groove at the bottom of the extension, the length of the extension preferably corresponds to the thickness between the coupling holes of the support block.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the prefabricated retaining wall block according to the present invention.

For convenience of description, the thicknesses of the lines and the size of the elements shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

1 is a perspective view showing a support block of a prefabricated retaining wall block according to an embodiment of the present invention.

As shown, the support block 100 has a long rod shape, the longitudinal direction of the support block 100 is arranged in a plurality of rows along the outer surface of the incision.

The support block 100 has a cross-section of the upper and lower symmetrical shape, and has a structure that can be stacked up and down regularly.

The front surface 120 of the support block 100 forms a surface of the retaining wall. The convex portion 122 protrudes convexly in order to improve the appearance of the retaining wall structure and to absorb noise and to prevent slipping on the retaining wall structure. ). The convex portions 122 are formed above and below, respectively, and are formed to be symmetrical to the center line C1.

The rear surface 140 of the support block 100 forms a flat surface. The back of the support block 100 is a portion that is filled with the filling material does not have to form the appearance or to consider the noise absorption, etc., unlike the front has a simple shape.

As described above, since the upper end 160 and the lower end 180 of the support block 120 have a symmetrical shape with respect to the center line c1, the following description will be made based on the upper end 160 and have a symmetrical shape. The description of the lower end 180 will be omitted.

The upper end 160 is a portion where the rear surface 140 and the front surface 120 are connected, and is also a portion directly coupled to the binding block 200 described later in FIG. What should be considered in the shape of the upper end 160 is to have a shape that can be easily fitted with the binding block 200, and has a shape that can be easily separated from the mold. To this end, the present invention has an upper end portion 160 having a shape in which the rear surface 140 is widest and narrower toward the front surface 120. In other words, since the upper end portion 160 has a cross section inclined downward from the rear surface 140 toward the front surface 120, the support block 100 manufactured in the mold can be easily separated from the mold.

In addition, the upper end 160 and the lower end 180 are provided with coupling holes 162, 164, 182, and 184 at predetermined intervals. The coupling holes 162, 164, 182, and 184 are formed in the vertical direction toward the center line at the upper end 160 or the lower end 180. Forming depth of the coupling holes (162, 164, 182, 184) is preferably formed to be 1/3 or less of the height of the entire support block (100). The coupling holes 162, 164, 182, and 184 are intended to prevent the strength of the neck 190 generated by facing each other.

The coupling holes 162, 164, 182, and 184 have a width corresponding to a cross-sectional thickness of the groove of the binding block 200, which will be described later. The coupling holes 200 are fitted into the coupling holes to be fixed to each other.

Figure 2 is a perspective view showing the binding block of the prefabricated retaining wall block according to an embodiment of the present invention.

The binding block 200 is installed in a direction perpendicular to the support block (100 in FIG. 1), and serves to connect the support blocks 100 and the upper and lower support blocks 100 of different rows to each other. Specifically, the binding block 200 is inserted into the coupling holes 162, 164, 182, and 184 of the support block 100 to connect the upper and lower support blocks 100 and the support blocks on the outer and inner surfaces thereof.

The binding block 200 also has a shape in which the top and bottom symmetry similarly to the support block 100. The binding block 200 has coupling grooves 212, 214, 216, 218 on both side surfaces of the front part and the rear part. One binding block 200 is combined with one support block 100 in each coupling groove 212, 214, 216, and 218 to be combined with a total of four support blocks 100.

The coupling grooves 212, 214, 216, and 218 are recessed grooves corresponding to the cross-sectional shapes of the upper end and the lower end of the support block 100 so as to be symmetrically formed up and down with respect to the center line C2 of the binding block 200. The gap t between the coupling grooves 212 and 26 is equal to the gap between the support blocks 100 at the upper and lower ends when the support blocks 100 are stacked.

When the supporting blocks 100 to be stacked are in close contact with each other, the water permeability or drainage property is not good, and thus, the supporting blocks 100 are preferably stacked at a predetermined interval. However, if the interval is too large, since the inner filling material may flow out at intervals between the support blocks 100, the interval is preferably set to about 1 ~ 6cm.

3 is a perspective view showing a state in which a support block and a binding block of a prefabricated retaining wall block according to the present invention are stacked.

As shown, the support blocks 100 are stacked alternately with each other by a stagger, and the outer surface support block 100-1 forming the surface of the retaining wall and the inner side support block 100-2 in contact with the surface of the cutout are bound. The blocks 200 are connected to each other so that the inside thereof has a lattice structure.

According to the present invention, the structure may be formed of the support block 100 and the binding block 200 alone without a separate connecting means by being coupled to each other by the fitting structure of the support block 100 and the binding block 200.

 The inner side S of the lattice form formed by the binding block 200 and the support block 100 is filled with a filling material, and a filling material is also filled between the inner side support block and the surface of the cutout. The filler may be used to generate the material generated in the field.

By the way, when both ends of the retaining wall has a shape as shown, the filling material filled in the inner space of the binding block 200 and the support block 100 is a gap G between the binding block 200. There is a risk of outflow. When the filler inside the retaining wall flows outward, the weight of the retaining wall is reduced, which affects the strength of the retaining wall.

In order to prevent this, by using a side binding block as described later in Figure 4 to prevent the interior of the filling material to flow out to the side.

Figure 4 is a perspective view showing an embodiment of a side binding block of the prefabricated retaining wall block according to the present invention.

As shown, the side binding block 300 has the same coupling grooves 312, 314, 316, 318 as the binding block (200 in Figure 2), the length is also formed the same as the binding block 200 do. However, the side binding block 300 has an extension portion 320 formed to extend downwardly between the coupling grooves (316, 318). The extension part 320 fills the gap G between the binding block (200 of FIG. 3) and the binding block (200 of FIG. 3) in the assembled retaining wall block. To this end, the length L of the extension part 320 preferably corresponds to the width of the gap G.

The gap G is equal to the thickness of the neck (190 in FIG. 1) between the coupling holes (162 and 182, or between 164 and 184) of the support block 100, and consequently of the extension 320 The length corresponds to the thickness of the neck of the support block 100.

In addition, the lower end of the extension 320 is provided with a drain groove (322). When the side binding block 300 is stacked, the upper and lower side binding blocks 300 closely adhere to each other, as shown in FIG. 5, and the drain groove 322 is extended to extend water 320 so that the water inside the retaining wall can be discharged. It is preferable to provide at the bottom of the). If the water inside the retaining wall is not discharged smoothly, the risk of retaining wall collapse due to hydraulic pressure increases.

Figure 5 is a perspective view showing a state laminated by using the side binding block of the prefabricated retaining wall block according to the present invention.

As shown, the side binding block 300 is coupled to the support block 100 in the same manner as the binding block 200, the extension 320 of the upper side binding block 300 is the lower side binding block ( It is in close contact with the upper surface of 300-1). Therefore, when the side binding block 300 is used at both edges of the retaining wall, the left and right ends of the retaining wall are blocked. Since the front and rear surfaces of the retaining wall are blocked by the support block 100, as a result, it is possible to provide a structure in which the filling material inside the entire retaining wall cannot flow out. In addition, even when the side surface of the retaining wall is exposed to the outside, it may have a beautiful appearance that the surface blocked by the side binding block 300 is exposed.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.

As described above, the prefabricated retaining wall block according to the present invention is excellent in workability by providing a structure in which the supporting blocks are stacked in a staggered structure, and the binding block and the side binding block are sandwiched with their own irregularities therebetween.

In addition, the left and right sides and the front and rear surfaces of the retaining wall are blocked so that the filling material inside the retaining wall does not leak to the outside to maintain a constant strength.
