Wave Dissipating Block with Submerged Function and Structure using it}

The present invention relates to a sofa block having a locking function, and more particularly, a hollow habitat space portion is formed in the center of a block body manufactured to have the shape of a tetrahedron as a whole, and the surface of the four virtual vertices facing each other and It relates to a sofa block having a locking function in which a flat surface is formed in a shape cut to be parallel, and a water hole is formed in the virtual four-sided part to communicate with the habitat space part.

The coast has a beautiful natural environment and is a highly effective place where a port for trade is installed, but the wind generated wave destroys coastal facilities or makes it difficult for ships to dock, depending on the size. A continuous wave causes scouring.

Breakwater is the most representative disaster prevention structure known to the general public, and it is located on the coast and serves to protect local residents and coastal facilities from waves. In particular, it functions to facilitate berthing and operation of ships for maritime activities by reducing the wave energy of the inland sea divided by the breakwater.

These breakwaters have to be able to resist wave force sufficiently, so they were made by stacking rocks in the past. It is a tetrapod (Tetrapod).

On the other hand, sofa blocks are manufactured in various shapes and their own weight according to the mounting method. Self-weight sofa blocks that resist waves by securing their own load sufficiently, and binding type sofa blocks that resist waves by cohesion between adjacent sofa blocks. , can be classified into friction-type sofa blocks that resist breakage by frictional force through surface contact between adjacent sofa blocks.

However, since the sofa block aims to effectively crush waves, it must increase its own weight or secure structural stability based on solidarity, and furthermore, it must be able to dissipate energy by diverting the flow of running water in multiple directions. That is, if sufficient amount of concrete is secured, its own weight can be increased, but if sufficient voids are not formed, reflected waves are generated and the breakwater is deformed or the energy dissipation efficiency is lowered, so that the sofa function cannot be exhibited, so a high porosity can be secured. there should be

For this reason, as shown in FIG. 1 (a), self-weighted sofa blocks such as caisson have a filling material inside and try to secure porosity by forming a lattice hollow part, but most of the hollow parts adopt a lattice-type monotonous structure. As a result, there was a limit that the sofa efficiency was not high.

In addition, as shown in (b) of Figure 1, by forming a pod in a branched shape similar to that of a tetrapod to implement interlocking between adjacent sofa blocks while providing a gap therebetween various types of binding type Sofa blocks have been proposed. However, these binding-type sofa blocks are structurally unstable due to their shape and inevitably have to be laminated, but there is a problem in flowing with strong wave energy, which causes safety accidents such as tripping.

Furthermore, as shown in (c) of FIG. 1, by laminating construction so that adjacent sofa blocks face each other, friction-type sofa blocks that resist waves are formed based on frictional force between sofa blocks, and grooves or stones are formed on the surface of the sofa blocks. An attempt was made to crush the wave based on the three-dimensional shape by additionally forming the part, but the effect of energy dissipation was extremely limited.

In addition, the conventional sofa blocks also function as latent agents, but most of them have the main purpose of preventing the loss of sand due to the excavation phenomenon. The current situation is to manufacture and install fish reefs.

The present invention has been proposed to solve the above problems, and by implementing a stable binding force between adjacent sofa blocks, effective resistance to waves is possible and high porosity is ensured, so that energy dissipation efficiency can be promoted, and aquatic life An object of the present invention is to provide a sofa block having a latent function that can be expected to function as a reef for habitation, has excellent construction efficiency, and has a high utility as a civil engineering structure, and a laminated structure using the same.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the following examples. This example is provided to more completely explain the present invention to those of ordinary skill in the art.

The sofa block (DB) having a locking function of the present invention is to form a laminated structure (BS) such as a breakwater so that a plurality of them are laminated as shown in FIG. 2 to resist the wave, primarily structurally stable sofa It is proposed to provide a structure, and furthermore, to function as a submerged submersible block (DB), which is eco-friendly by realizing that it does not block the flow of running water, and provides a habitat for aquatic organisms.

As shown in Fig. 3a, the sofa block DB according to an embodiment of the present invention is made of reinforced concrete to have a tetrahedral shape as a whole and is formed as a single block body 10 integrated. The block body 10 may be manufactured at a factory and transported to the shore to be constructed, but depending on the scale, a formwork is provided near the shore to solve the difficulty of transportation, and reinforcing bars 50 to be described later are provided. After arranging the inside, the block body 10 can be produced by pouring concrete.

On the other hand, the sofa block (DB) of the present invention has a hollow form space portion 20 is formed in the center of the block body 10 to communicate with the water hole 40 to be described later to induce the flow of running water. It can function as a habitat for living things, and since the running water flowing into the plurality of running water holes 40 in different directions can function as an intersection where they cross each other, it is possible to provide a very advantageous space as a habitat.

As shown in the conceptual diagram of Figure 3b, the block body 10 of the present invention is formed to be close to the shape of a tetrahedron as a whole, so that the four sides (shown by hatching) on which the water holes 40 to be described later are formed are extended and formed. A tetrahedron is defined as a virtual tetrahedron, and four virtual vertices and four virtual faces are defined based on this virtual tetrahedron.

As shown in FIG. 3 , a flat surface 30 is formed in the block body 10 in a shape in which four imaginary vertices are cut parallel to opposite surfaces. The block body 10 has a quadrangular truncated pyramid shape by the flat surface 30, but the flat surface 30 is formed at all four vertices. The flat surface 30 is structurally stable and the convex body By removing the tip in (10), the ease of construction can be secured, and the occurrence of a safety accident can be prevented in advance.

In addition, as shown in Figures 4 to 6, the virtual four-sided portion of the block body 10 may be formed with a water hole 40 so as to communicate with the template space (20). In the case where the flowing water hole 40 is arranged in a positive direction so that one side faces downward, the flow of flowing water can be induced from three sides that have different directions as a whole, so the organic relationship with the above-described habitat space unit 20 is obtained. Effective energy dissipation is possible based on the flow of multi-directional running water. In addition, in the center of the block body 10, a hollow nesting space portion 20 is formed so that a high porosity can be secured, so that the sofa efficiency can be improved.

On the other hand, the block body 10 is made of integrated reinforced concrete, but six column parts 11 are formed at the corners by the above-described form space 20 and water hole 40, and the flat The flat portion 12 is formed so that the surface 30 is formed on the outside to have a constant thickness.

That is, since the block body 10 has a high porosity by the habitat space portion 20 and the water hole 40, the reinforcing bar 50 is provided in the column portion 11 and the flat portion 12 for structural reinforcement. ), it is possible to reinforce the tensile load acting on the column part 11, and it is possible to achieve structural stability while ensuring the porosity.

In addition, the column part 11 is composed of a plurality of outer column surfaces 11a exposed to the outside and a plurality of inner column surfaces 11b formed inside based on the four virtual surfaces of the block body 10 to form a polygon. It may be formed to have a cross-section. At this time, based on the four virtual surfaces of the block body 10, a surface formed outside the block body 10 is defined as an outer column surface 11a, and a surface formed inside the block body 10 is defined as an inner column surface 11b.

The column part 11 is a structural part formed by the habitat space part 20 and the water hole 40 and induces flow of water in multiple directions. It is preferable to be formed of a plurality of outer column surfaces 11a and inner column surfaces 11b having different directions.

In addition, in each column part 11 , a groove part 13 may be formed to a predetermined depth along the plurality of outer column surfaces 11a . The groove part 13 promotes construction efficiency by providing a binding part in the stacking construction process of the sofa block DB using a crane, and provides structural stability to prevent mutual slippage in stacking a plurality of sofa blocks DB. can be promoted

On the other hand, as described above, the block body 10 is formed to have the column part 11 and the flat part 12 by the habitat space part 20 and the water hole 40, so that the overall block weight is reduced and the porosity is high. It can be expected, but it can act as a structural weakness. In particular, a strong tensile load may be generated in the column unit 11 due to a load due to stacking or waves.

In order to solve this problem, as shown in FIG. 7 , it is preferable to reinforce the reinforcing bars 50 as a tension member so as to be interconnected, and the reinforcing bars 50 are provided in the column part 11 in the longitudinal direction. A main reinforcing bar 51 is provided, and the main reinforcing bar 51 may be formed to be surrounded by a rectangular stirrup reinforcing bar 52 .

In addition, triangular reinforcing bars 53 are reinforced adjacent to the flat surface 30 in the flat portion 12, and hexagonal reinforcing bars 54 are spaced apart from each other inside the triangular reinforcing bar 53, and the triangular reinforcing bars ( 53) and the hexagonal reinforcing bars 54 are formed to surround the different main reinforcing bars 51 reinforced in the three column sections 11, thereby achieving structural integrity between the column section 11 and the flat section 12.

In addition, in the flat part 12 , which is the part where the three column parts 11 meet, a binding bending part 51a obtained by extending and bending any one of the main roots 51 of each column part 11 is formed, so that three binding bending parts are formed. Tensile reinforcement and structural integrity can be expected by binding the parts 51a to each other.

On the other hand, below, a plurality of sofa blocks (DB) of the present invention shown in FIG. 2 will be described in more detail with respect to the sofa block stacked structure (BS) formed by stacking.

The sofa block stacked structure (BS) of the present invention is formed by stacking at least four sofa blocks (DB) with each other, and at the same time, at least a virtual surface is shared while ensuring a binding force in the relationship with the adjacent sofa blocks (DB) It is proposed to enable effective resistance to waves by providing frictional force by stacking them as much as possible.

To this end, the individual sofa blocks (DB) are formed with a hollow form space part 20 in the center of the block body 10 having the shape of a tetrahedron as a whole as described above, and the block body 10 is a virtual four The flat surface 30 is formed in a shape in which the vertex is cut parallel to the opposing surface, and the four imaginary surface portions of the block body 10 communicate with the living space portion 20 so that the water hole 40 is formed. is formed

At this time, since the sofa block DB has a structure close to a tetrahedron as a whole, it may be arranged with one virtual surface facing downward to enable upright, and in the present invention, this is defined as 'regular arrangement', and one Arranged so that the virtual surface faces upward is defined as 'reverse arrangement'.

As shown in Fig. 8a, the laminated structure (BS) of the sofa block of the present invention includes at least three sofa blocks (DB) that are regularly arranged so that one virtual surface faces downward. The sofa blocks DB are arranged so that at least one virtual surface excluding the lower part is parallel to each other in relation to the adjacent sofa blocks DB to form an equilateral triangle structure in plan view.

Furthermore, as shown in FIG. 8b , in the middle of the three sofa blocks DB, the sofa blocks BD are reversely arranged so that one virtual surface faces upward, and the three sofa blocks DB and each of the three sofa blocks DB are adjacent to each other. It is formed to share one side.

Accordingly, the laminated structure (BS) using the sofa block (DB) of the present invention can be laminated to share a virtual surface based on the combination of the normal arrangement and the reverse arrangement by forming the block body 10 as a whole in a tetrahedral shape. Thus, it is possible not only to secure the locking force, but also to form frictional force in multiple directions. As a result, structural stability is secured between the sofa blocks, so that it is possible to provide a sofa block capable of effective resistance to waves while providing a high porosity.

In addition, by combining the forward and reverse arrangement of the sofa block (DB), it is possible to expect a frictional resistance effect of more than a multi-layer sofa block while lowering the overall height of the sofa block.

In addition, according to the embodiment, the flat surface 30 of the three sofa blocks DB, which are normally arranged to form an equilateral triangle structure on a plane, and the virtual one surface facing the upper part of the sofa block DB, which are arranged reversely in the middle, are mutually It can be manufactured to form the same plane.

As a result, the flat surface 30 of the sofa block placed in the normal position and the virtual upper surface of the sofa block placed in the reverse direction can provide a flat surface by forming the same plane as each other. As a result, high usability can be expected.

And depending on the arrangement form, a tight space may be provided by the flat surface 30 formed by disposing a plurality of sofa blocks DB to function as a habitat for aquatic organisms.
