Description

High blue-adaptive sofa block

The present invention relates to a sofa block, and more particularly, to a high-wave-responsive sofa block which is installed in a breakwater that protects the coast from waves incident on the shore from the outer sea and reduces incident waves and reflected waves generated from the breakwater. will be.

In general, sofa blocks are installed in port structures such as breakwaters and shore banks, and when the blue waves invade the sea, they break the waves and reduce the forces of the waves. Also, the waves are reflected by hitting the structure by passing the waves through the air gaps between the installed sofa blocks. And by reducing the rise of the wave has the function of preventing breakage of the harbor structure such as breakwaters, lakes and the like to prevent the wave to the sea side.

Such a common sofa block is advantageous to attenuate a large amount of blue waves at a time when a large number of voids between the installed sofa blocks are secured, so that the installation is made in various forms with a large number of pillars or feet for easy installation and many voids. This breaks the waves through multiple poles or feet and weakens them so that they do not radiate again in the voids with other sofa blocks.

Therefore, the number of blue contact surfaces on the surface of the sofa block as much as possible to increase the area that the blue touches, it will be crushed finely by resistance, and the sofa effect is increased, such as to sharply weaken the breakdown and to prevent the rise and reflection of waves and waves of reflected waves and waves. .

However, the existing sofa block is composed of a cylinder protruding a square pyramid, and the surface of the column has a circular cross section, so the blue bumps on the surface bounce off without much resistance or slide slightly apart from the front of the column. As you go out, there is a problem that the blue is not crushed smoothly.

In addition, the existing sofa block is difficult to cope with the high blue wave 10m or more frequently caused by the recent rapid climate change, there is a problem that a portion of the column is broken or the structure itself is broken by the high blue impact.

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

The sofa block of the prior art, as shown in Figure 1, the central body 110, a plurality of radially extending from the central body and the first connection portion 120 which is integral with the central body and the first formed at the end of the first connection portion It consists of one block 135, the second connecting portion 140 which extends up, down, left and right from the central body and is integral with the central body, and the second block 155 formed at the end of the second connecting portion.

However, the sofa block of the prior art can not be naturally bound with another sofa block because the connecting

portions

120, 140 and

blocks

135, 155 extending from the center body form an approximately hexahedron, and a separate fastening There is a limitation that must be connected through the member.

On the other hand, there is a polygonal sofa block proposed in Republic of Korea Patent Publication No. 10-1214463 as another prior art.

The prior art is the configuration of the connection pillar, the lower support legs in three directions on both sides of the connection pillar to form a hexagonal as a whole.

Such prior art has a problem that the legs are formed in a cylindrical shape and insufficient to crush the blue, and the protrusions are formed on each leg, which makes manufacturing troublesome.

In addition, the sofa block of the prior art has a problem that the leg is vulnerable to breakage because it lacks a configuration that can be reinforced of the connection portion of each leg.

For example, the drainage, the leg extension portion forming an extension of the radiating leg while protruding to the maximum width in the center of the block body; And a haunting portion connecting both ends of the leg extension portion and both ends of the block body with a slope of a flat surface or a curved surface, respectively.

In addition, the present invention, protruding in the form of connecting the leg extensions of the neighboring drainages of the drainage to each other while connecting the end of the drainage side of the radiating legs in the form of an inclined surface in the circumferential direction It may be configured to further include; leg bridge portion to expand.

In addition, the present invention further comprises an additional haunch which forms both the end portions of the leg haunch with both ends of the block body in a planar or curved inclination, respectively, and forms the cross-section of the drainage form together with the leg haunch portion. Can be.

The present invention may further include a wedge portion which protrudes in a wedge shape at each end of the radiating leg and protrudes in an inclined direction in the same direction as the drainage.

In addition, the block body is formed of a regular polygonal pillar, the length of one side constituting the regular polygon may be formed the same as the width and height of the radiation leg.

In addition, the length of the radiation leg, may be formed shorter than the sum of the length of one side constituting the regular polygon of the block body and the protruding length of the drainage.

In addition, the maximum protrusion length of the drainage may be formed shorter than the length of one side constituting the regular polygon of the block body.

According to the sofa block according to the present invention, as the bleeding protrudes on each vertical plane of the block body constituting the polygonal pillar, the stiffness is improved because the connecting portions of the limbic leg are reinforced by the bleeding as the limbic legs are extended to each bleed. It is not easy to break even in high-incidence blue, and even when the broken leg is broken, the shedding remains in a protruding state, thereby maintaining structural stability.

Specifically, in the present invention, as the radiating legs are extended to the leg extensions forming the maximum protrusion of the shedding, the haunting portions forming the inclined surfaces are formed at both ends of the leg extensions, so that the radiating legs are connected in an inclined shape rather than at right angles, so that the cross-sectional area is increased. This extension can improve the resistance to forces and moments on the spinning leg.

In addition, the present invention can be firmly bound while being easily interlocked with the sofa blocks because the wedge portion is formed at the end of the radiating legs to easily penetrate into the space with another sofa block around.

In addition, according to the present invention, since the block bodies are formed of regular polygonal pillars, the radiating legs are formed corresponding to the number of vertical planes of the block body, respectively, so that the number of radiating legs can be differently produced according to the site situation.

In addition, the present invention is easy to design and manufacture because the width and height of the spinning leg is formed equal to the length of one side of the block body.

In addition, the present invention is not easily broken as the length of the spin leg is shorter than the sum of the protruding length of the block body and drainage, even if all the spinning legs are cut stability through the weight of the block body and drainage Can provide.

The sofa block according to the present invention is installed on the outer sea side of the breakwater while being interlocked with another sofa block to reduce the wave incident to the shore by reducing the block body 100, as shown in FIG. It may be configured to include (200) and a plurality of radiating legs (300).

The block body 100 is a part forming the center of the sofa block.

The block body 100 is formed of a concrete structure while being made of a concrete structure to provide a weight.

Here, the block body 100 is formed in the form of a square pillar, that is, a rectangular parallelepiped as shown in FIGS. 3 and 4 to provide four vertical surfaces along the circumference, as shown in FIG. It can be formed to provide six vertical planes along the perimeter.

Of course, the block body 100 may be composed of a triangular pillar, a pentagonal pillar or a hexagonal pillar or more unlike shown.

Drainage 200 is a component that reinforces the connection portion of the block body 100 and the radiating leg 300 while providing an extended portion of the radiating leg 300 to be described later formed protruding along the circumference of the block body 100. .

These drainages 200 are formed to protrude while forming a drainage structure on each of the vertical plane constituting the block body (100).

That is, the drainage 200 has a structure in which the protrusion width is increased toward the central portion of the block body 100 while being protruded along the longitudinal direction on the vertical surface constituting the block body 100.

Therefore, the drainage 200 functions to reinforce the connecting portion of the radiating leg 300, and maintains stability while remaining in the protruding state along the circumference of the block body 100 even when the radiating leg 300 is damaged. Let's do it.

More specifically, the drainage 200 may include a leg extension 210 and haunche 220 as shown in FIG.

The leg extension part 210 provides an extension part of the radiating leg 300 to be described below while making a maximum protrusion length at the center of each vertical surface of the block body 100.

Here, the protruding length L3 of the drain 200 by the leg extension 210 may protrude shorter than the length L2 of one side constituting the regular polygon of the block body 100 as shown in FIG. 4. (This description is limited to the length as an example, and may be left as it is for the purpose of refusal by the JPO examiner.)

The haunting unit 220 protrudes in the form of connecting both ends of the leg extension unit 210, that is, the upper and lower ends and the upper and lower ends of the block body 100, respectively.

The haunch 220 may be formed while forming a planar inclined surface as shown in FIGS. .

Radiating leg 300 is a component that extends to each of the above-described shedding 200 to form a radial bridge around the block body 100 while interlocking with the legs of another sofa block to provide a binding force.

As shown in FIG. 3, the radiating leg 300 protrudes along the protruding direction to the leg extension 210 constituting the drainage 200.

Here, the radiating leg 300, when the block body 100 is formed as a hexagonal column as shown in Figure 7, each extends to six vertical planes to form six quantities.

Meanwhile, as shown in FIG. 3, the radiating leg 300 may be extended while forming a rectangular parallelepiped shape having the same width and height as the length of one side forming the regular polygon of the block body 100.

In addition, as shown in FIG. 4, the length L1 of the radiating leg 300 is shorter than the sum of the length L2 of one side constituting the regular polygon of the block body 100 and the protruding length L3 of the drainage 200. (This description is limited to the length as an example, and may be left as it is for the purpose of rejecting the KIPO examiner.)

Accordingly, the radiation leg 300 is formed to extend in the form of the connection portion with the block body 100 is reinforced by the drainage 200, so that the rigidity is reinforced is not easily broken even by high-incidence blue.

In addition, even when the broken leg 300 is broken, the block body 100 and the shedding 200 remain in weight while providing stability, and the other bleeding block as the shedding 200 remains in a protruding state. Bond strength can also be maintained.

On the other hand, the radiating leg 300 may be formed to extend in the form of a cylinder or a hexagonal or octagonal pillar, unlike shown.

In addition, as shown in Figure 3 and 4, the radiating leg 300 may be formed with a wedge portion 350 to form a wedge at the end.

As shown, the wedge part 350 is formed at the distal end of the spinning leg 300 while forming an inclination in the same direction as the inclination direction of the haunting part 220 of the above-described drainage 200.

Accordingly, the radiating leg 300 can be easily engaged while interlocking by digging into the space with another sofa block through the wedge unit 350.

And, the sofa block of the present invention may be configured to further include a leg hunt 400 as shown in FIG.

Leg hunt 400 is protruding in the form of connecting the leg extension portion 210 of the above-mentioned fold 200, the shedding 200 of each other.

That is, the leg hunt 400 is connected to the radiating leg 300 by expanding the cross-sectional area of the block body 100 in the circumferential direction while connecting the end portions of the drain 200 of the neighboring radiating legs 300 in an inclined surface shape. Reinforce it.

Accordingly, the radiation leg 300 is a structure for the incident wave because the connection portion with the block body 100 is reinforced by the haunch 220 in the longitudinal direction, and at the same time is reinforced by the leg haunch 400 in the horizontal direction Stability can be even greater.

In addition, the sofa block of the present invention may be configured to further include an additional hunt 450 as shown in FIG.

The additional hunt portion 450 forms a cross section of the shedding 200 together with the above-described leg hunt portion 400, and is formed on both ends of the leg hunt portion 400, that is, the upper end and the lower end of the block body 100. It is formed to protrude so that the lower end is connected to each in the form of a slope.

That is, the additional hunt portion 450 is formed to protrude between the drainage 200 adjacent to each other with the leg hunt portion 400 to reinforce the connecting portion of the radiation leg (300).

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

At this time, the sofa block of the present invention is installed in a state of binding while digging into the space of another sofa block through the wedge 350 formed at the end of the radiating leg 300.

In addition, the sofa block of the present invention breaks the blue by contacting the incident wave through the surface of the drainage 200 made of a polygon or the surface of the radiation leg 300, and breaks the reflected wave of the blue wave through the air gap with the other sofa block. do.

At this time, the radiating leg 200 breaks the blue while maintaining the binding force without being damaged by the blue as the connecting portion is reinforced by the haunche 220 of the drainage 200.

As described above, the sofa block according to the present invention, as the drainage 200 is protruded to each vertical surface of the block body 100 forming a polygonal pillar as the radiation leg 300 is extended to each drainage 200 Since the connection part of the radiating leg 300 is reinforced by the shedding 200, the strength is improved, so that it is not easily broken even in the high-incidence blue, and even when the radiating leg 300 is broken, the shedding 200 protrudes. Since it remains in (100), it is possible to maintain structural stability.

Although specific embodiments of the present invention have been described above, these are merely for the purpose of description and are not intended to limit the protection scope of the present invention. It will be apparent to those skilled in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.

The sofa block of the present invention can be used in the breakwater or revetment structure or the like because the connection part of the radiating bridge is reinforced by the drainage to improve the rigidity and stability.
