1, a concrete block 1 according to an embodiment of the invention is continuously coupled by a cable 2, on a slope 4 leading to a river or sea 5 from a weir 3. Can be located. In this case, the slope 4 may be referred to as an x-y plane.

The concrete block 1 is connected by a cable, so that it can be positioned fluidly according to the inclination of the slope 4. That is, since the concrete block 1 according to an embodiment of the present invention is connected to the cable between the concrete block 1 by the cable 2, it can have flexibility and adaptability to the slope of the various slopes (4). In addition, the concrete block 1 can reduce the capillary phenomenon of fine granules because the ground adhesion is increased.

2, the concrete block 1 which continues from the weir 3 is shown. At this time, the concrete block 1 is connected in both directions in the x-axis direction and the y-axis direction by the cable 2 can prevent the separation between the concrete block (1).

3 shows a state in which the concrete block 1 is joined by a crane. As can be seen in Figure 3, the concrete block (1) coupled in both directions by the cable (2) can be lifted by the crane in the mutually coupled state, so that it can be carried in the coupled state and positioned on the slope.

When the combination of the concrete block 1 is lifted by the crane 6 as shown in FIG. 4, the concrete block 1 receives more load as it is located in the center portion. Thus, the concrete block 1 located in the center portion is gravity More down in the direction, the concrete block (1) located at the edge of the crane (6) hardly goes down. Thus, the combined concrete block 1 may form a curved cross section.

5 is a plan view of a concrete block according to an embodiment of the present invention, Figure 6 is a perspective view of a concrete block according to an embodiment of the present invention, Figure 7 is a perspective view of a coupling protrusion of a concrete block according to an embodiment of the present invention 8 is a side view of the AA of Figure 5, Figure 9 is a side view of the engaging projection of the concrete block according to an embodiment of the present invention.

According to FIG. 5, the concrete block 1 includes a body 10, coupling protrusions 21, 22, and 23, first coupling holes 31, 32, and 33, and second coupling holes 41, 42, and 43. It may include.

Body 10 has a constant thickness, the bottom surface of the body 10 is in contact with the slope of the river or the shore. The body 10 may serve as a prop to which the coupling protrusions 21, 22, and 23 to be described later may be attached.

In Figure 6, the body 10 is shown in the form of a rectangular parallelepiped, the body 10 may be a cylindrical shape or the like as needed, all forms that a person skilled in the art can easily think of.

Referring back to FIG. 5, the coupling protrusions 21, 22, and 23 may be attached to the body 10 and may be formed in plural. Coupling protrusions 21, 22, 23 are located at the upper end and the lower end of the body 10, inducing coupling in the x-axis direction between the concrete blocks. That is, the coupling protrusion located at the upper end of the body 10 of the concrete block 1 may be engaged with the coupling protrusion located at the lower end of another concrete block body. That is, the plurality of concrete blocks 1 may be continuously coupled in the x-axis direction by the coupling protrusions 21, 22, and 23.

In addition, as illustrated in FIG. 7, the coupling protrusion 23 may have a convex shape on one surface thereof. Coupling protrusion 23 of the convex shape of one surface, it is possible to reduce the friction between the blocks by reducing the area in contact when engaging with other concrete blocks.

As shown in FIG. 8, the coupling protrusion 23 may have the same thickness as the body 10. When the thickness of the coupling protrusion 23 and the thickness of the body 10 are the same, the concrete block 1 may have a uniform thickness as a whole.

As shown in FIG. 9, the thickness of the coupling protrusion 23 may be different from the thickness of the body 10. At this time, the thickness of the coupling protrusion 23 may be thinner than the thickness of the body (10). When the thickness of the coupling protrusion 23 is thinner than the thickness of the body 10, the coupling protrusion 23 may be located at the center of the height of the body 10. In addition, the coupling protrusion 23 may be located at the upper or lower side of the center of the height of the body (10).

The structure of the coupling protrusion 23 and the body 10 may be variously configured according to the needs of the user. For example, when the coupling protrusion 23 is located below the height of the body 10, the concrete block 1 may also be used as a stair because the body 10 protrudes from the concrete block 1.

Referring to FIG. 5 again, the first coupling holes 31, 32, and 33 may be formed through the coupling protrusions 21, 22, and 23. One coupling protrusion 21, 22, 23 may include one first coupling hole 31, 32, 33. The first coupling holes 31, 32, and 33 may be formed to be parallel to the coupling protrusions 21, 22, and 23 in the y-axis direction.

The cable may be inserted into the first coupling holes 31, 32, and 33. In this case, the cables inserted into the first coupling holes 31, 32, and 33 may be inserted in the y-axis direction. The cable inserted into the first coupling holes 31, 32, and 33 may be coupled to a plurality of concrete blocks so that the plurality of concrete blocks may not be separated from each other in the x-axis direction. The first coupling hole of the coupling protrusion located at the upper end of the body 10 may be discontinuously connected to the first coupling hole of the coupling protrusion located at the lower end of another concrete block body. As one continuous cable is inserted into two discontinuously connected first coupling holes, the concrete block may be fixed. However, the concrete block can be fluid because it is connected by cables. The second coupling holes 41, 42, and 43 may be formed through the coupling protrusions 21, 22, 23, and the body 10 simultaneously. In this case, the second coupling holes 41, 42, and 43 may be formed in the x-axis direction. One coupling protrusion 21, 22, 23 may include one second coupling hole 41, 42, 43, and if necessary, the coupling protrusion 21, 22, 23 may have a second coupling hole ( 41, 42, 43) may not be included. That is, only two coupling protrusions 21 and 22 of the three coupling protrusions 21, 22 and 23 may include the second coupling holes 41 and 42.

The cable may be inserted into the second coupling holes 41, 42, 43. In this case, the cables inserted into the second coupling holes 41, 42, and 43 may be inserted in the x-axis direction.

The cable inserted into the second coupling holes 41, 42, 43 may be coupled to a plurality of concrete blocks so that the plurality of concrete blocks may not be separated from each other in the y-axis direction. When the engaging projection located at the upper end of the body 10 of the concrete block 1 is engaged with the engaging projection located at the lower end of another concrete block body, the second engaging holes of the two concrete blocks may be connected to each other. As one continuous cable is inserted into two discontinuously connected second coupling holes, the concrete block may be fixed. However, because concrete blocks are connected by cables, they can be flexible.

10 is a perspective view of a body of a concrete block according to an embodiment of the present invention. Referring to FIG. 10, the concrete block 1 may have a structure in which one surface of the body 10 is convex. Preferably, the concrete block 1 may have a structure in which an opposite surface of the bottom surface is convex.

The central portion 15 of the body 10 is protruded so that the body 10 may be a semi-circular cross-sectional shape. For example, when a slope of a river or a coast is formed in the xy plane, and the bottom surface of the body 10 of the concrete block 1 is in contact with the slope, the central portion 15 of the body 10 moves in the z-axis direction. It can be protruding. At this time, the wave hits the central portion 15 of the protruding body 10, and thus the wave pressure may be attenuated.

11 is a perspective view of a body of a concrete block according to another embodiment of the present invention, Figure 12 is a plan view showing a convex surface and a concave surface of the concrete block according to an embodiment of the present invention.

11 and 12, the body 10 of the concrete block 1 according to an embodiment of the present invention, the outer surface of the body 10 is one surface that is not attached to the engaging projection (21, 22, 23) It may be composed of a convex surface 51 protruding toward the other side, the other surface may be composed of a concave surface 52 recessed inwardly of the body (10). In this case, the convex surface 51 and the concave surface 52 may have the same outer surface shape of the convex surface 51 and the inner surface shape of the concave surface 52. At this time, the convex surface 51 of the concrete block 1 may be inserted into the concave surface of the other concrete block.

13 is a plan view of a combined state of a plurality of concrete blocks according to an embodiment of the present invention. Referring to FIG. 13, the convex surface 51 and the concave surface 52 have the same outer surface form of the convex surface 51 and the inner surface form of the concave surface 52, so that the convex surface of the concrete block 1a is made of other concrete. It can be inserted into the concave surface of the block 1b. Accordingly, the plurality of concrete blocks 1a and 1b may be more stably coupled in the y-axis direction.

14 is a perspective view showing a combination of two concrete blocks according to an embodiment of the present invention and Figure 15 is a side view showing a combination of two concrete blocks according to an embodiment of the present invention.

According to FIG. 14, when the first concrete block 1a and the second concrete block 1b are coupled in the x-axis direction, the first concrete coupling protrusion is disposed between the coupling protrusions 22b and 21b of the second concrete block 1b. As the 23a is inserted, the three coupling protrusions 23a, 22b, and 21b may be engaged with each other. In this case, the first coupling holes 32b and 31b of the second concrete block 1b and the first coupling hole 33a of the first concrete block 1a may be placed on a straight line. As one continuous cable (not shown) is inserted into three discontinuous first coupling holes 31b, 32, b, and 33a, the first concrete block 1a and the second concrete block 1b may be coupled to each other. have.

Referring to FIG. 15, the coupling protrusion 23a of the first concrete block 1a may partially overlap the coupling protrusion 21b of the second concrete block 1b. At this time, the coupling protrusion 21b may have a convex shape. In this case, the area in which the coupling protrusion 21b contacts the body 10a of the first concrete block 1a may be reduced. Accordingly, when the first concrete block 1a and the second concrete block 1b are coupled, friction between the concrete blocks 1a and 1b is reduced and wear of the concrete blocks 1a and 1b can be prevented. .

16 is a side view showing a combination of three concrete blocks according to an embodiment of the present invention. As described above, when the concrete block (1a, 1b, 1c) coupled to the cable 20 by lifting the crane, the angle to the horizontal line of the concrete block will vary for each concrete block.

As can be seen in FIG. 16, if the first concrete block 1a is a concrete block at the midpoint of the crane, the second concrete block 1b is inclined more than the first concrete block 1a, and the third concrete block ( 1c) is tilted further than that.

When one surface of the engaging projection of the concrete block 1b is convex, even if the convex curved surface of the engaging projection is in contact with the body of the other concrete block 1a, the concrete block 1b is rotatable along the convex curved surface. Therefore, the concrete block 1b in which one surface of the coupling protrusion is convex may maintain the coupling between the concrete blocks even at various slopes.

If the concrete blocks 1a, 1b, 1c can hold the bonds to various inclinations, the concrete blocks 1a, 1b, 1c can be transported in the engaged state. In addition, the concrete blocks (1a, 1b, 1c) of the combined state can be installed on various slopes.

When the concrete block 1 is configured as described above, the concrete block can be moved in fluidity along the curved portion in contact with the concrete blocks. Accordingly, it is easy to transport and combine the concrete block, the construction time for installing the concrete block on the slope can be shortened. In addition, the concrete block can be applied to all the various slopes of the slope, it is possible to increase the adaptability to the slope.

17 is a side view showing a combination of two concrete blocks according to another embodiment of the present invention. Referring to FIG. 17, the coupling protrusions 21a and 21b are thinner than the thicknesses of the bodies 10a and 10b and are located on the upper portions of the bodies 10a and 10b. Even in this case, if one surface of the coupling protrusion 21b is convex, the concrete block 10b may be advantageously coupled at an angle.

18 is a perspective view of a concrete block according to another embodiment of the present invention. In the concrete block according to the present embodiment, one surface of the body 10 is convex. In addition, the convex projections 21, 22, and 23 do not include convex surfaces. In this case, when the concrete block is combined with another concrete block, both concrete blocks are in contact with the convex portion of the body 10, so the fluidity between the concrete blocks can be increased.

19 is a plan view of a concrete block including a coir felt according to an embodiment of the present invention. The concrete block 1 may include a coir felt 60 containing coir as a main raw material and containing seeds. In this case, the coir felt 60 may be located at the center of the concrete block 1.

Coyer refers to a fiber obtained from the outer shell of coconut, a fruit of Cocos nucifera, belonging to the arecaceae family. Coir felt 60 may be prepared by embedding and pressing the seeds of the plant in the coir.

Coir felt 60 may be utilized as a vegetation space. The concrete block 1 including the coir felt 60 may be used as a revetment block on a river slope.

Coir is also environmentally friendly as it can be obtained from nature, and can contain plant seeds to enable plant growth.

Hereinafter, a concrete material is demonstrated.

The concrete of the concrete block 1 may be a mixture of a polycarboxylic acid-based organic admixture in a cement mixed with portland cement, blast furnace slag and gypsum.

Portland cement is the most commonly used cement, with a sufficient proportion of raw materials containing the main components lime, silica, alumina and iron oxide. At this time, the portland cement may be ordinary portland cement (OPC) of Korean Industrial Standard KS L 5201.

The blast furnace slag may be a blast furnace slag powder having a powder level of 5000 cm ² / g to 7000 cm ² / g. At this time, the blast furnace slag fine powder may be mixed in the same amount as the Portland cement.

Gypsum may be a mixture of anhydrous gypsum and dihydrate gypsum in a ratio of 2: 1. In this case, the cement mixed with the gypsum may be mixed and ground to have a powder degree of 4000 cm ² / g or more.

In addition to cement, aggregate, and water, admixtures are materials added to give concrete a special quality or to improve properties. In this case, the admixture may be mixed with 0.015 to 0.030% of the weight of the cement as a polycarboxylic acid-based organic admixture.

By using such a concrete material, the mechanical strength can be increased.

In Table 1, OPC usually refers to concrete using Portland cement, BFC refers to concrete in which 50% of OPC is replaced with blast furnace slag powder, and HBFC refers to concrete added with gypsum mentioned above in BFC.

According to Table 1, the compressive strength of 7 days of OPC showed 29.4 MPa, whereas the BFC decreased 23% strength to 22.5 MPa, while HBFC showed 32.3 MPa, 30% higher than BFC and 9% higher than OPC. Compressive strength is increased.

In general, incorporation of admixtures such as blast furnace slag fine powder into Portland cement may reduce premature strength. However, the use of a material such as HBFC may solve the premature strength deterioration problem.

Table 2 shows the test results of the chlorine ion penetration resistance test conducted according to the standard of the test method of chlorine ion penetration resistance of concrete by KS F 2711 electrical conductivity. As a result, HBFC shows that the total charge amount is 324 Coulombs at 28 days of age, which is higher in salt resistance than BFC and OPC.

By using such a concrete material, the surface peeling resistance can be increased.

Table 3 shows the results of the test for surface peeling resistance based on the test method for surface peeling resistance by freezing and thawing of concrete surface exposed to ASTM C 672 ice making salt. The peeling resistance test is an experiment to verify the degree of exposure of aggregate in concrete. After 50 cycles of freezing and thawing, the amount of surface peeling was 23.5g for HBFC and 189.6g for OPC. As shown in Table 3, HBFC has the highest resistance to surface peeling due to freezing and thawing.

20 is a view showing an experimental result comparing the surface peeling resistance of the concrete material according to an embodiment of the present invention. 20 shows the degree of exposure of aggregates of OPC 71, BFC 72 and HBFC 73 after 50 cycles of freezing and thawing. Referring to FIG. 18, the OPC 71 is rated as 5, the BFC 72 is rated 1, and the HBFC 73 is rated 0 according to the apparent grade of ASTM C 672. That is, the exposure degree of aggregate of HBFC 73 is the smallest, and the resistance to surface peeling is the largest.
