Description

ARMOR UNIT AGAINST HIGH WAVE

The present invention relates to a sofa block, and more particularly, to a sofa block provided on a breakwater for protecting the coast from waves incident on the coast from the outside sea to reduce the wave of incident waves and the reflected waves generated from the breakwaters will be.

Generally, the sofa block is installed in a harbor structure such as a breakwater, a sea shore, etc., and when a large wave from the sea breaks waves, it breaks waves to reduce the power of wave. Also, it permeates waves through the space between installed sofa blocks, And the rise of wave gears to prevent breakage of port structures such as breakwater and shore,

Such a conventional sofa block is advantageous to attenuate a large amount of waves at a time because a lot of space between installed sofa blocks must be secured. Therefore, it is manufactured in various forms having many pillars or feet, Thereby weakening the waves so that the waves do not emit again in the pores of the other sofa blocks.

Therefore, as long as the contact surface of the wave block is as large as possible, the surface area of the wave is increased, and the wave is crushed by the resistance, and the wave is abruptly weakened to prevent the rising and falling of the reflected wave and wave. .

However, since the existing sofa block is composed of a cylinder protruding in the shape of a square horn, the surface of the column has a circular cross-section, so that the wave hitting the surface protrudes without any resistance or slips slightly from the front of the column There is a problem that the wave can not be smoothly pulverized as it goes out.

In addition, existing sofa blocks are difficult to cope with high waves of 10 m or more, which frequently occur due to recent rapid climate change, and there is a problem that a part of a column is broken or a structure itself is damaged by such a high-impact.

On the other hand, there is a sofa block proposed in Korean Patent Registration No. 10-1399812 as a sofa block of the prior art.

As shown in FIG. 1, the sofa block of the prior art includes a central body 110, a first connecting portion 120 formed integrally with the central body, a plurality of which extend radially from the central body, and a second connecting portion 120 formed at the end of the first connecting portion. And a second block 155 formed at an end of the second connection part. The second connection part 140 is formed integrally with the central body. The second connection part 140 extends vertically and horizontally from the center body.

However, the sofa block of the prior art can not be naturally tied to another sofa block since the connecting portions 120 and 140 and the blocks 135 and 155 extending from the central body form a substantially hexahedron, There is a limit to be connected through the member.

On the other hand, as another prior art, there is a polygonal sofa block proposed in Korean Patent Registration No. 10-1214463.

The prior art is composed of connecting pillars and three supporting pillars on both sides of the connecting pillars.

This prior art has the problem that the legs are formed in a cylindrical shape and are not enough to crush the waves, and protrusions are formed on the respective legs.

In addition, the sofa block of the prior art lacks a structure in which the connecting portions of the respective legs can be reinforced, so that there is a problem that the legs are vulnerable to breakage.

The sofa block of the present invention including the above-mentioned components is installed along the longitudinal direction of the breakwater or the coastal structure so as to break the incident wave and reduce the wave.

At this time, the sofa block of the present invention is inserted into the space of another sofa block through the chamfered portion 400 formed at the end of the leg portion 300, and is interlocked and installed in a state of being engaged.

The sofa block of the present invention breaks the wave by making contact with the incident wave through the surface of the protrusion 200 or the surface of the leg 300, and breaks the reflected wave of blue through the gap with the other sofa block.

At this time, as the connection part of the leg part 200 with the body part 100 is reinforced by the protrusion part 200, the wave part breaks the wave while maintaining the binding force without being damaged by the wave.

As described above, in the sofa block according to the present invention, the trapezoidal protrusions 200 are protruded from the vertical surfaces of the body portions 100 forming the rectangular parallelepiped, and the leg portions 300 of the rectangular parallelepiped are extended from the respective trapezoidal protrusions 200 The connecting portion between the leg portion 300 and the main body portion 100 is reinforced by the trapezoidal protrusion portion 200 according to the present invention so that the stiffness is improved so that it is not easily damaged even in the high incident wave. (200) remains in a protruded state, so that structural stability can be maintained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.
