Description

Sofa block and offshore structure to which it is applied {WAVE DISSIPATION BLOCK AND OCEANIC STRUCTURE USING THE SAME}

The present invention relates to a tetrapod-type sofa block capable of improving rigidity, porosity and interlocking performance, improving sofa performance, and providing a stable habitat for marine ecosystems.

In general, a sofa block is an offshore structure that dissipates wave energy so that high waves in the open sea do not reach the inland sea or land as they are. These sofa blocks are used in a static or difficult way for various offshore structures such as breakwaters, quay walls, and jamje.

The sofa block is evaluated for its technical value by the porosity generated by mounting the sofa block in a static or difficult way, and the K _d value determined by the shape and mounting method of the sofa block.

For example, if the sofa block is poorly designed or mounted poorly to increase the porosity, the foundation stone leaks or the sofa block moves and collides and is damaged, resulting in damage to the body.

In addition, the sofa block, the volume (tonne) is determined in response to the marine environment in which the sofa block is constructed and installed. For example, the greater the design wave height of the ocean, the greater the self-weight of the sofa block is designed.

Meanwhile, in the sofa block, the binding force (interlocking) between neighboring sofa blocks is also one of the most important factors. If the design wave height is too large, the construction cost increases significantly, resulting in an inefficient design. Conversely, if the design wave height is too tight, the sofa block is helpless at the wave height exceeding it. Therefore, the interlocking between neighboring sofa blocks is one of the most important design factors so that an appropriate design wave height can be set and the sofa blocks do not float away or are damaged even at an unexpected wave height that exceeds the design wave height. .

However, excessive interlocking is a factor that makes it difficult to install the sofa block, so an appropriate compromise is required.

The present invention has been devised to solve the above problems, and it is possible to secure high rigidity and porosity, and has a large wave energy dissipation ability, and to provide a sofa block that is well interlocked and not difficult to install. do.

The technical gist of the present invention for solving the above problems is applied to a tetrapod-type sofa block including four main leg parts 10 extending from the center of a virtual tetrahedron toward each vertex of the tetrahedron.

The cross section of the main leg part 10 may be circular or regular polygonal. The regular polygon may be, for example, an equilateral triangle or a regular hexagon. Of course, the cross section does not necessarily have to be a regular polygon, and may be a general polygon (triangle, hexagon, etc.).

The main leg unit 10 may be in the form of a truncated cone whose cross section decreases from the center of the sofa block toward the end of the main leg unit 10, or may be in the form of a column having a constant cross section.

The sofa block 1 has a main goal to further include a sub-leg part 30 at the end of the main leg part 10 .

When the sub-leg part 30 protrudes long in the radial direction from the main leg part 10, a high porosity is ensured, the wave energy dissipation ability is large, and interlocking is well done, but installation is not difficult.

The sub-leg part 30 may be provided on all four main leg parts 10 . In some cases, the sub-leg part 30 may be provided only in the three main leg parts 10 , only in the two main leg parts 10 , or in only one main leg part 10 .

When the sofa block provided with the sub-leg part 30 is mounted only on a part of the main leg part 10, the main leg part 10 provided with the sub-leg part 30 is directed downward, and the sub-leg part 30 is provided. The main leg portion 10 that has not been oriented may be mounted in an upward direction.

However, the cross-sectional shape of the radial angle is not necessarily limited thereto, and as described above, if the width of the cross-section is greater than the height of the cross-section, it is of course possible to transform into various shapes such as a flat oval shape.

The strength of the three radial portions 40 may be secured by the connection portion 50 between them. The connecting portion 50 may be disposed between the two adjacent radial portions 40 to connect the two adjacent radial portions 40 . This can be understood as being like the webbing of a flipper.

The length of the connecting portion 50 radially extending from the center of the sub-leg portion 30 is equal to or greater than the length of the radial angle portion 40 extending radially from the center of the sub-leg portion 30 . can be small

[First embodiment]

Hereinafter, a first embodiment of a sofa block according to the present invention will be described with reference to FIGS. 1 to 5 .

The sofa block of the first embodiment may be substantially in the form of a tetrapod.

That is, the sofa block 1 may have a shape including four main leg parts 10 extending from the center of the virtual tetrahedron toward each vertex of the tetrahedron.

According to the first embodiment, the shape of the cross section of the main leg part 10 (a plane cut in a plane perpendicular to the central axis of the leg part) is substantially circular. And the main leg part 10 is in the form of a truncated cone whose cross section decreases from the center of the sofa block toward the end of the main leg part 10 . That is, the main leg portion 10 has a substantially truncated cone shape.

For convenience of explanation, the main leg part facing upward when the sofa block is placed on the ground among the four main leg parts is referred to as the first main leg part, and the remaining main leg parts in contact with the ground are called the second main leg part and the third main leg part, respectively. referred to as a leg part and a fourth main leg part. However, these are referred to as such for convenience of description, and there is substantially no difference in the shapes of the first main leg part to the fourth main leg part.

A sub-leg part 30 is connected to an end of the main leg part 10 .

The sub-leg part 30 is perpendicular to the central axis of the main leg part 10 and has a flat plate shape having a predetermined thickness.

The sub-leg part 30 includes three radial angle parts 40 extending in a centrifugal direction from the central axis of the main leg part 10 . The radial angle portions 40 are arranged at intervals of 120 degrees around the central axis of the main leg portion 10 .

The three radial portions 40 are radially extended on a plane.

The cross-sectional shape of the radial angle part 40 cut in a plane perpendicular to the extension direction of the radial angle part 40 has a direction perpendicular to the imaginary central axis of the main leg part 10, the main leg part 10 It may be in the form of a rectangle longer than the direction parallel to the imaginary central axis of . For ease of explanation, the cross-section of the radial portion 40 may have a flat rectangular shape. Of course, as mentioned above, the cross-sectional shape is not necessarily limited thereto.

The sub-leg part 30 further includes a connection part 50 therebetween.

The connecting portion 50 may be disposed between the three radial portions 40 , respectively. That is, three connecting portions 50 may also be provided at intervals of 120 degrees. The inter-connection portion 50 is disposed between the two adjacent radial portions 40 to connect the two adjacent radial portions 40 , and the radial portion 40 has its strength by the inter-connection portion 50 . can be reinforced.

A length in which the connecting part 50 extends radially from the center of the sub-leg part 30 is smaller than a length in which the radial angle part 40 extends radially from the center of the sub-leg part 30 . Accordingly, the radial portion 40 protrudes more in the centrifugal direction than the interconnection portion 50 .

Referring to FIG. 3 , the direction in which the radial angle part 40 extends from the end of the main leg part 10 is the same as the direction in which the main leg part 10 and the remaining three main leg parts 10 adjacent to each other extend. it's in the opposite direction Then, as shown in FIG. 5 , one radial angle part 40 of the sub leg part 30 provided at the end of the second main leg part to the fourth main leg part comes into contact with the ground. This places the sofa block 1 slightly higher from the ground than the form in which the two radial portions 40 are in contact with the ground. Accordingly, the orientation of the radiation angle portion 40 increases the porosity of the sofa block 1 .

The sofa block 1 has a form protruding in the centrifugal direction from the circumferential surface of the main leg unit 10 and includes a first beam unit 13 extending in the longitudinal direction of the main leg unit 10 . .

The first beam unit 13 may have a Y-shape. Specifically, the first beam part 13 is in the form of connecting three adjacent main leg parts 10 .

The first beam part 13 protrudes in the centrifugal direction from the surface of the main leg part 10, and the three main leg parts 10 from the point where all three neighboring main leg parts 10 meet at the center of the sofa block. It is a form extending in a Y-shape to the end of the leg portion 10 . Accordingly, the first beam part 13 is formed in a portion adjacent to the first main leg part, the second main leg part, and the third main leg part, and the first main leg part, the second main leg part, and the fourth main part. The leg parts are formed in adjacent parts, and the first main leg part, the third main leg part, and the fourth main leg part are formed in adjacent parts, and the second main leg part, the third main leg part, and the fourth main leg part are formed. An addition may be formed in a neighboring site. As such, four first beam units 13 may be provided.

The first beam part 13 can further secure the strength of the main leg part 10 while reducing the area of the cross-section of the main leg part 10 , and in particular, in a radial direction from the central axis of the main leg part 10 . By being disposed at the furthest position to the, the bending rigidity of the main leg portion 10 is greatly reinforced. Since the first beam part 13 itself is made of concrete, the first beam part 13 can exert a very large resistance to compressive force or shear failure occurring along its longitudinal direction.

For example, when the first main leg unit receives an external force that bends toward the second main leg unit and the third main leg unit, the first beam unit is formed in adjacent parts of the first main leg unit, the second main leg unit, and the third main leg unit. In (13), the beam part provided in the first main leg part receives compressive force or shear force. As described above, since the first beam part 13 itself is made of concrete, the first beam part 13 is the first main leg part. It greatly resists the external force bending the leg. In addition, since the first beam part 13 formed in the first main leg part extends to the second main leg part and the third main leg part, the first beam part 13 extended to the second main leg part and the third main leg part. The beam part 13 exerts an effect of supporting the first beam part 13 part of the first main leg part.

In addition, for example, when the first main leg unit receives an external force that bends toward the fourth main leg unit, in the first beam unit 13 formed in a region adjacent to the first main leg unit, the second main leg unit, and the fourth main leg unit. In the beam portion provided in the first main leg portion and the first beam portion 13 formed in a region adjacent to the first main leg portion, the third main leg portion, and the fourth main leg portion, the beam portion provided in the first main leg portion compresses the compressive force. Alternatively, a shear force is applied. As described above, since the first beam part 13 itself is made of concrete, the two first beam parts 13 greatly resist the external force bending the first main leg part. In addition, since the two first beams 13 formed in the first main leg part extend to the second main leg part and the fourth main leg part, respectively, and extend to the third main leg part and the fourth main leg part, The first beam portion 13 extending to the second main leg portion and the fourth main leg portion and the first beam portion 13 extending to the third main leg portion and the fourth main leg portion are the first It exhibits the effect of supporting the two first beam parts 13 of the first main leg part.

Additionally, in the interior of the first beam part 13, reinforcing bars may be reinforced along the longitudinal direction thereof. Then, for example, when the first main leg part receives an external force bending toward the second main leg part and the third main leg part, the first beam part provided in the first main leg part, the second main leg part, and the fourth main leg part In (13), the beam of the second main leg part of the first beam part 13 provided in the first main leg part, the first main leg part, the third main leg part, and the fourth main leg part. In addition, the first main leg unit resists tensile force or shear force generated when the first main leg unit is bent toward the second main leg unit and the third main leg unit, thereby greatly resisting the external force bending the first main leg unit.

This effect will be the same even when, for example, the first main leg part receives an external force that bends toward the fourth main leg part.

In addition, the sofa block 1 further includes a second beam unit 15 . The second beam part 15 is formed at a portion where the two adjacent main leg parts 10 contact each other in order to reinforce the proximal ends of the two adjacent main leg parts 10 .

The second beam part 15 is protruded from the surface of the main leg part 10 in the centrifugal direction, and is made of any one along the periphery of the part where two adjacent main leg parts 10 meet at the center of the sofa block. It may extend from the center of the first beam part 13 to the center of the first beam part 13 adjacent thereto. In the sofa block of the tetrapod type as in the first embodiment, six second beam portions 15 as above are provided.

If necessary, reinforcing bars may also be provided in the second beam unit 15 .

Since the second beam part 15 is formed along a portion where two adjacent main leg parts 10 contact each other in the center of the sofa block, as shown in FIGS. 2 and 4, the three adjacent main leg parts 10 With the center of the meeting point, three portions of one Y-shaped first beam unit 13 are arranged at intervals of 120 degrees, and three second beam units 15 are arranged at intervals of 120 degrees. This can be said to have the same shape as when the six beam parts are arranged at intervals of 60 degrees around the part where the three neighboring main leg parts 10 meet.

Accordingly, for example, when the first main leg unit receives an external force that bends toward the second main leg unit and the third main leg unit, the first main leg unit, the second main leg unit, and the third main leg unit are formed in adjacent parts. In the first beam part 13, the beam part provided in the first main leg part resists compressive force and shear force, and a part of the first beam part 13 extending to the second main leg part and the third main leg part; The compression or shearing resistance of the second beam part 15 between the second main leg part and the third main leg part supports the compression or shearing resistance of the first beam part 13 provided in the first main leg part. In addition, if reinforcing bars are provided in the second beam part 15 , the second beam part 15 between the first main leg part and the second main leg part and the second beam part between the first main leg part and the third main leg part The tensile or shear resistance of (15) supports the first beam part 13 provided in the first main leg part.

That is, no matter which direction the main leg part receives an external force, both the first beam part 13 and the second beam part 15 extending in various directions provide sufficient resistance to the stress generated by the external force.

As such, the first beam part 13 and the second beam part 15 of the first embodiment greatly reinforce the strength of the main leg part 10, and even if the cross section of the main leg part 10 is small, the main leg part 10 to prevent breakage in the In addition, the first beam part 13 and the second beam part 15 provide rigidity that can sufficiently resist stress generated in the main leg part 10 due to the sub-leg part 30 being subjected to an external force. do.

In addition, since the first beam part 13 and the second beam part 15 provide a significant curvature to the smooth surface of the tetrapod, the wave effect is greatly increased. In addition, this shape provides an excellent habitat for marine ecosystems.

In the first embodiment, it is exemplified that the cross-sectional shapes of the first and second beams 13 and 15 are rectangular. However, as described several times, this is only exemplary, and the cross-sectional shape may vary.

The first beam part 13 is connected to the back surface of the sub-leg part 30 connected to the end of the main leg part 10 . That is, both the main leg part 10 and the first beam part 13 are connected to the back surface of the sub leg part 30 . The first beam part 13 reinforces the strength of the connection portion between the sub-leg part 30 and the main leg part 10 . In addition, since the first beam part 13 is directly connected to the sub-leg part 30 , when the sub-leg part 30 receives an external force, the distance between the sub-leg part 30 and the main leg part 10 is In addition to reinforcing the connection portion, it also resists stress generated in the main leg portion 10 due to an external force applied to the sub-leg portion 30 .

In one sub-leg part 30 , three first beam parts 13 are connected at intervals of 120 degrees.

According to the first embodiment, the first beam part 13 is connected to the radiation angle part 40 . Accordingly, it is possible to more stably support the radial portion 40 protruding more outward than the connecting portion 50 in the radial direction.

And the sub-leg part 30 is a connecting part surface beam part that protrudes from the surface of the inter-connection part 50 and extends from the center of the sub-leg part 30 to the ends of the three inter-connection parts 50 in a Y-shape. (53) is provided.

Accordingly, it can be said that six of the surface beam parts 43 and the connection part surface beam parts 53 are radially extended at intervals of 60 degrees. It has the same shape as the six beam units arranged at intervals of 60 degrees. Accordingly, the each part surface beam part 43 and the connecting part surface beam part 53 are similar to the first beam part 13 and the second beam part 15 for strength reinforcement, wave breaking ability, porosity improvement and marine ecosystem habitat space provision, etc. can exert the effect of

Also, if necessary, reinforcing bars may also be provided in the each part surface beam part 43 and the connecting part surface beam part 53 .

Then, for example, when one of the radiation angle parts 40 receives an external force and the surface beam part 43 of the corresponding radiation angle part 40 receives a compressive force or shear force, this compressive force or shear force is of the other two radiation angle parts 40 . It can be further supported by the compressive resistance of the connecting part surface beam part 53 of the each part surface beam part 43 and the connecting part 50 provided therebetween, and the tension of the connecting part surface beam part 53 of the other two connecting parts 50 is Or it may be further supported by shear resistance.

The cross section of each part surface beam part 43 and the connecting part surface beam part 53 is square.

The each part surface beam part 43 and the connecting part surface beam part 53 may increase the surface curvature of the sub-leg part 30, thereby improving the sofa effect. In addition, it becomes an excellent habitat for marine ecosystems.

On the other hand, although not directly described in the description of the embodiment, a chamfer can be added to prevent breakage of the sharp corner of the sofa block and to solve the sharpness, and the cross-section of the deep corner (the corner of the structure) can be reinforced and easy Of course, it is possible to form a haunchi for demolding the formwork.

[Seventh embodiment]

Hereinafter, a seventh embodiment of the sofa block according to the present invention will be described with reference to FIGS. 31 to 35 . Matters not directly described in the seventh embodiment may be fully understood from the description of the corresponding content in other embodiments.

Since the sofa block of the seventh embodiment is the same as that of the first embodiment in the shape of the main leg part 10 itself and the sub-leg part 30, the overlapping description will be omitted.

In comparison with the first embodiment, the sofa block of the seventh embodiment is provided with a third beam part 17 instead of the second beam part 15 being omitted.

The sofa block 1 has a shape protruding from the circumferential surface of the main leg unit 10 in the centrifugal direction, and has a first beam unit 13 and a third extending along the longitudinal direction of the main leg unit 10 . A beam portion 17 is provided.

The first beam unit 13 may have a Y-shape. Specifically, the first beam part 13 is in the form of connecting three adjacent main leg parts 10 .

The first beam part 13 protrudes in the centrifugal direction from the surface of the main leg part 10, and the three main leg parts 10 from the point where all three neighboring main leg parts 10 meet at the center of the sofa block. It is a form extending in a Y-shape to the end of the leg portion 10 . Accordingly, the first beam part 13 is formed in a portion adjacent to the first main leg part, the second main leg part, and the third main leg part, and the first main leg part, the second main leg part, and the fourth main part. The leg parts are formed in adjacent parts, and the first main leg part, the third main leg part, and the fourth main leg part are formed in adjacent parts, and the second main leg part, the third main leg part, and the fourth main leg part are formed. An addition may be formed in a neighboring site. As such, four first beam units 13 may be provided.

The third beam unit 17 may have an I-shape. Specifically, the third beam unit 17 is configured to connect two adjacent main leg units 10 .

The third beam unit 17 is protruded in the centrifugal direction from the surface of the main leg unit 10, and the two main legs from a point where two neighboring main leg units 10 meet at the center of the sofa block. It is a form extending in an I-shape to the end of the part 10 .

By being disposed at the furthest position to the, the bending rigidity of the main leg portion 10 is greatly reinforced. Since the first beam part 13 itself is made of concrete, the first beam part 13 can exert a very large resistance to compressive force or shear force generated along its longitudinal direction.

The third beam unit 17 can also reduce the area of the cross-section of the main leg unit 10 and further secure the strength of the main leg unit 10 . When the cross-sectional shape of the main leg unit 17 is circular or hexagonal, the third beam unit 17 is also disposed at the position furthest from the central axis of the main leg unit 10 in the radial direction, so that the bending rigidity of the main leg unit 10 is will be greatly reinforced. When the cross-sectional shape of the main leg unit is an equilateral triangle, the third beam unit 17 is disposed at a position farthest in the radial direction from the central axis of the main leg unit 10 , so that the bending rigidity of the main leg unit 10 . will be greatly reinforced.

Since the first beam part 13 and the third beam part 17 themselves are composed of concrete, the first beam part 13 and the third beam part 17 exert a very large resistance to the compressive force or shear force generated along the longitudinal direction. can

For example, when the first main leg unit receives an external force that bends toward the second main leg unit and the third main leg unit, the first beam unit is formed in adjacent parts of the first main leg unit, the second main leg unit, and the third main leg unit. (13), a third beam unit 17 formed in a region adjacent to the first main leg unit and the second main leg unit, and third beam units 17 formed in a region adjacent to the first main leg unit and the third main leg unit. In the above, the beam parts provided in the first main leg part are subjected to compressive force or shear force. As described above, since the first beam part 13 and the third beam part 17 themselves are made of concrete, the corresponding part is the first main part. It greatly resists the external force bending the leg. In addition, since the first beam part 13 and the third beam part 17 formed in the first main leg part extend to the second main leg part and the third main leg part, the second main leg part and the third main leg part The first beam part 13 and the third beam part 17 extending to the leg part exert an effect of supporting the first beam part 13 and the third beam part 17 part of the first main leg part.

In addition, in the interior of the first beam part 13 and/or the third beam part 17, reinforcing bars may be reinforced along the longitudinal direction thereof. Then, the first beam part 13 and/or the third beam part 17 can resist tensile force and shear force.

As such, the first beam part 13 and the third beam part 17 of the seventh embodiment greatly reinforce the strength of the main leg part 10, and even if the cross section of the main leg part 10 is small, the main leg part 10 to prevent breakage in the In addition, the first beam part 13 and the third beam part 17 provide rigidity that can sufficiently resist stress generated in the main leg part 10 due to the sub-leg part 30 being subjected to an external force. do.

In addition, since the first beam portion 13 and the third beam portion 17 provide considerable curvature to the smooth surface of the tetrapod, the sofa effect is greatly enhanced.

In the seventh embodiment, it is exemplified that the cross-sectional shapes of the first beam part 13 and the third beam part 17 are rectangular.

That is, the main leg part 10 , the first beam part 13 , and the third beam part 17 are all connected to the back surface of the sub leg part 30 . The first beam part 13 and the third beam part 17 reinforce the strength of the connection part between the sub-leg part 30 and the main leg part 10 . And, since the first beam part 13 and the third beam part 17 are directly connected to the sub-leg part 30, when the sub-leg part 30 receives an external force, the sub-leg part 30 and In addition to reinforcing the connection portion between the main leg parts 10 , it also resists stress generated in the main leg part 10 due to an external force applied to the sub-leg part 30 .

In one sub-leg part 30, three first beam parts 13 are connected at intervals of 120 degrees, and three third beam parts 17 are connected at intervals of 120 degrees, and the first beam part 13 and The third beam units 17 are arranged at intervals of 60 degrees.

Accordingly, the sub-leg part 30 can be supported more stably by both the radial angle part 40 and the connecting part 50 between them.

The sub-leg part 30 is a leg part surface beam part protruding from the surface of the radial angle part 40 and extending from the center of the sub leg part 30 to the ends of the three radial angle parts 40 in a Y-shape ( 43) is provided.

First, the offshore structure on which the sofa block 1 of the first embodiment is mounted is shown in FIGS. 56 to 58 .

The two radial angles facing upward of the sub-leg part of the second main leg part of the sofa block mounted so that the first main leg part is upward are mounted adjacent thereto and the third main leg part of the sofa block mounted so that the first main leg part is mounted upward. and the fourth main leg part are interlocked with the first beam part, respectively (refer to part b of FIGS. 56 and 58).

Similarly, two radial angle portions facing upward of the sub-leg portion of the second main leg portion of the sofa block mounted so that the first main leg portion is supported on the ground are placed adjacent thereto and the sofa block mounted so that the first main leg portion is placed upward. is interlocked with the first beam part of the third main leg part and the fourth main leg part, respectively (see part c of FIG. 56 ).

In addition, the sub-leg parts provided at the ends of each main leg part are positioned in the space between the sofa blocks at various angles and shapes.

Next, the offshore structure on which the sofa block 1 of the tenth embodiment is mounted is shown in FIGS. 59 to 62 .

The three radial angles of the sub-leg part of the second main leg part of the sofa block mounted so that the first main leg part is mounted upward (downward), and the third of the sofa block mounted so that the first main leg part is mounted so that the first main leg part is upward (downward). It is disposed between the main leg part and the sub-leg part of the fourth main leg part and is interlocked (see part a in FIGS. 60 and 62 ).

In addition, the three radial parts of the sub-leg part of the second main leg part of the sofa block mounted to the first main leg part upward (downward) are adjacent to this and the third of the sofa block mounted so that the first main leg part is mounted downward (upward). It is interlocked with the radial angle part of the main leg part and the sub leg part of a 4th main leg part (refer part d of FIG. 60).

In this way, the sub-leg parts of the neighboring sofa blocks are very reliably interlocked with each other due to many radiation angle parts and beam parts.

Previously, the mounting form of FIGS. 56 to 62 was based on the B arrangement shown in FIG. However, the mounting method of the sofa block of the present invention is not limited thereto. For example, the sofa block may be mounted based on the arrangement A shown in FIG. 64 . According to the sofa block of the present invention, it can be confirmed that the interlocking between the sofa blocks in the longitudinal and lateral directions is made closely with only one layer of the A arrangement itself. In addition, as can be seen in FIG. 64, which is a plan view, when the sofa block is mounted, simply lowering the weighted sofa block allows interlocking to be performed at the same time as it is mounted. Such interlocking is made possible by neighboring sub-legs, which are made possible by the fact that the sub-legs extend radially in a plane substantially perpendicular to the central axis of the main leg.

65 to 68, it shows a method of mounting the sofa block with two layers in the form of hanging two feet. Referring to this, the sub-leg parts provided on the two main leg parts downward from the sofa block mounted on the second floor interlock with the beam part provided on the main leg part of the sofa block mounted on the first floor, and the sub-leg part of the sofa block mounted on the first floor. can confirm that it can be.

As such, the sofa block of the present invention forms a sub-leg part at the end of the main leg part, and by making the thickness of the main leg part reinforced by the beam parts thinner, the sofa block does not damage the porosity but rather increases the void ratio. and strength can be greatly increased.

In the offshore structure of the embodiment, a structure in which two layers are stacked on different one-story shapes is exemplified, but by using the sofa block of the present invention, three-story and four-story stacks are possible, as well as various shapes for each floor or within one floor Of course, it can be mounted in (two-foot hanging form like FIGS. 65 to 68, single-leg hanging type like FIGS. 59 to 62, etc.) and a combination thereof.

In addition, the sofa block of the present invention may be mounted with difficulty, and may be used for repair and reinforcement of an already constructed tetrapod offshore structure.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made. In addition, even if the effects of the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.

For example, among the shapes described above, the meaning that the cross-sectional shape is square means that the cross-sectional shape is substantially square. That is, if the corner portion of the square is chamfered, it can be technically called an octagon, but the practical effect is that it has the effect of a square, so it can be substantially called a square. In addition, for example, if both sides of the square have a slight inclination angle to facilitate demolding, it can be strictly called a trapezoid, but the practical effect is that it has a square effect, so it can be said that it is also substantially square. will be.
