Description

Wave dissipating blocks and arrangement structure of the wave dissipating blocks

The present invention relates to a sofa block and its arrangement structure, and more particularly, to a technology for reducing wind wave and running water energy by mounting it on a breakwater or a shore.

A sofa block, also called a geungo block, is a concrete block that protects the structure by attenuating the wave force that invades the breakwater or shore structure and reducing the reflected wave. Sofa blocks are effective in reducing wind and running water energy by installing them in groups on breakwaters, on the coast, or on the shores of rivers.

In the conventional sofa block, a tetrapod having four legs extending radially from the center is the most common, and a dimple that is a modified tetrapod is also used a lot in recent years. In addition, Patent Registration No. 10-1668735 (“sofa block and mounting method using the same”) as a patent on a sofa block has a shape similar to that of two tetrapods sharing one leg, and has three legs at both ends of the center. Discloses a sofa block provided.

However, the tetrapods are prone to scattering or shaking due to a large wave height due to lack of interlocking, and thus, a part of the structure is often damaged or lost. In the aforementioned patented technology, a total of six legs are formed radially from the center to improve interlocking between blocks, but the complexity of the structure increases, resulting in various problems in terms of block manufacturing, quality control, and construction.

The more complex the structure of the sofa block, the greater the difficulty of manufacturing, assembling, and dismantling the formwork for block production, which increases the manufacturing cost of the sofa block. In addition, the complexity of the block structure causes problems with the concrete quality of blocks, such as honeycomb generated on the block surface after concrete curing due to excessive vibrating during concrete pouring. In addition, the more complex the structure, the more difficult it is to keep the balance of the blocks being lifted in a balanced state or to mount the blocks in a specific position at a specific location, and there is a high risk that workers are exposed to the risk of safety accidents during construction.

Registered Patent Publication No. 10-1668735

An object of the present invention is to provide a sofa block and an arrangement structure thereof with improved convenience and mounting constructability of sofa blocks while improving interlocking properties between sofa blocks.

The side formwork 420 is a formwork that forms the side surface of the sofa block 100 when pouring concrete, and has a shape corresponding to the front, rear, left and right sides of the sofa block 100, respectively. Accordingly, the formwork 400 includes four side formwork 420 corresponding to each side of the sofa block 100 . Since the sides of the sofa block 100 are the same front, back, left and right, the four side molds 420 have the same shape. Therefore, the formwork 400 is easy to manufacture and assemble, and it is advantageous for maintenance and transport such as storage and maintenance.

After connecting the support plate 410 and the side formwork 420 , the sofa block 100 is manufactured by pouring and curing concrete through the upper opening of the formwork 400 . The formwork 400 has a structure in which it is easy to put a concrete compactor from the upper part to the lower part, so that it is easy to compact concrete in every corner, and high-quality concrete can be cured.

The side formwork 420 is dismantled when the concrete demolding strength of the sofa block 100 is secured, and can be directly connected to another support plate 410 and used repeatedly. The support plate 410 supporting the sofa block 100 cannot be used until the concrete transport strength is secured and the block can be moved. However, since the support plate 410 is very easy to manufacture, it is possible to manufacture and utilize the extra support plate 410 and connect the extra support plate 410 to the side formwork 420 to continuously manufacture blocks.

Hereinafter, a sofa block arrangement structure in which a plurality of sofa blocks are arranged will be described.

First, the first sofa block 100 is self-supporting on the ground with two legs, and the second sofa block 200 supports the ground with two legs and is disposed on the side of the first sofa block 100 . At this time, a part of the second support leg 220 of the second sofa block 200 is inserted into the second insertion groove 124 of the first sofa block 100 , and the first insertion groove of the second sofa block 200 . A portion of the first support leg 110 of the first sofa block 100 is inserted into the 214 .

In the one-layer structure, the legs of another sofa block are inserted into the first insertion groove and the second insertion groove of the sofa block to increase the interlocking properties between the sofa blocks. Referring to FIG. 4B , since the four legs of the sofa block are inserted into the insertion grooves of other sofa blocks in the vicinity, all sofa blocks constituting the arrangement structure are engaged with each other. Therefore, the cohesive force between the sofa blocks is strong and the durability to withstand the waves is increased.

Figure 4c shows that the above-described one-layer structure is mounted on the slope. As shown in FIG. 4C , the one-layer structure may be continuously disposed on the slopes. The slope of the slope is formed in a vertical-to-horizontal ratio of 1.3 to 2.0.

For example, the first sofa block 100 and the second sofa block 200 support the ground with either one of the second supporting legs and two legs of the first supporting leg, respectively. In addition, when the first sofa block 100 and the second sofa block 200 are arranged side by side in the lateral direction, the second support legs of the first sofa block 100 and the second sofa block 200 are in the same direction as each other. toward, and disposed with a predetermined interval (s) between the second support legs. The first sofa block 100 and the second sofa block 200 constitute the first floor of the arrangement structure.

The direction of the second support legs of the first sofa block 100 and the second sofa block 200 may be appropriately determined by a person skilled in the art according to field conditions. When mounted on a slope, the first sofa block 100 and the second sofa block 200 may be disposed to face the upper end or the lower end of the slope, or to be perpendicular to the inclination direction.

Therefore, the second support leg 320 of the third sofa block 300 is mounted over the top without passing through the gap (s) between the first sofa block 100 and the second sofa block 200 .

5B is a group bond in which unit bonds of the above-described two-layer structure are aggregated, and a plurality of unit bonds overlap. When a group is combined, a plurality of rows are arranged on the first floor, and blocks in each row may be alternately arranged. Referring to FIG. 5B , in the two-layer structure, the first sofa block 100 and the second sofa block 200 stably support the ground with three legs, and their behavior is changed by the load of the third sofa block 300 . Limited. In addition, the movement of the third sofa block 300 is constrained by the first supporting leg 310 by the first sofa block 100 and the second sofa block 200 and the other second floor blocks. Therefore, all the sofa blocks constituting the two-layer structure are interlocked, and the aggregation between the sofa blocks is strong and the durability to withstand the waves is increased.

Figure 5c shows the above-described two-layer structure mounted on the slope. As shown in FIG. 5C , the two-layer structure may be continuously disposed on the slopes. The slope of the slope has a vertical to horizontal ratio of 1.3 to 2.0.
