Description

Sofa block and marine structures using it {WAVE DISSIPATION BLOCK AND OCEANIC STRUCTURE USING THE SAME}

The present invention relates to a tetrapod-type sofa block that can improve rigidity, porosity, and interlocking performance, improve sofa performance, and provide a stable habitat for the marine ecosystem.

In general, a sofa block is a marine structure that dissipates wave energy so that high waves in the open sea do not directly reach the inland sea or landside. These sofa blocks are used in a static or passive manner for various marine structures such as breakwaters, quay walls, and dams.

The technical value of a sofa block is evaluated by the porosity generated by mounting the sofa block statically or randomly, and the K _d value determined by the shape and mounting method of the sofa block.

For example, if the sofa block is designed sloppily or placed sloppily in order to increase the porosity, the foundation riprap stone may leak out or the sofa block may move and hit and be damaged, causing damage such as destruction of the body.

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

Meanwhile, for sofa blocks, cohesion (interlocking) between neighboring sofa blocks is also one of the most important factors. If the design wave height is set too large, construction costs will increase significantly, resulting in an inefficient design. On the contrary, if the design wave height is set too tightly, the sofa block will be helpless against wave heights exceeding this. Therefore, it can be said that interlocking between neighboring sofa blocks is one of the most important design elements in order to set an appropriate design wave height and prevent the sofa blocks from floating away or being damaged even if the wave height is unexpected and exceeds the design wave height. .

However, excessive interlocking becomes a factor that makes installation of sofa blocks difficult, so an appropriate compromise is necessary.

The present invention was developed to solve the above-mentioned problems, and its purpose is to provide a sofa block that can secure high rigidity and porosity, has a large wave energy dissipation ability, interlocks well, and is not difficult to install. do.

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

The cross section of the main leg portion 10 may be circular or a regular polygon. 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 portion 10 may be in the form of a cone whose cross-section becomes smaller as it moves from the center of the sofa block to the end of the main leg portion 10, or may be in the form of a pillar with a constant cross-section.

The main point of the sofa block (1) is to further include a sub-leg portion (30) at the end of the main leg portion (10).

When the sub-leg portion 30 protrudes long in the radial direction from the main leg portion 10, a high porosity is secured, the wave energy dissipation ability is high, interlocking is good, and mounting construction is not difficult.

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

When mounting a sofa block in which sub-leg portions 30 are provided only on some of the main leg portions 10, the main leg portion 10 provided with the sub-leg portion 30 is directed downward, and the sub-leg portion 30 is provided.

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

The strength of the three radial parts 40 can be secured by the connection part 50 between them. The connection part 50 may be disposed between two neighboring radial parts 40 and connect the two neighboring radial parts 40. This can be understood as being similar to the flippers of flippers.

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

The direction in which the radial portion 40 extends from the end of the main leg portion 10 may correspond to the direction in which the remaining three main leg portions 10 adjacent to the main leg portion 10 extend. there is.

Accordingly, by increasing the section modulus (Z) of the main leg portion 10, the strength of the main leg portion can be significantly increased.

For example, when the cross section of the main leg portion 10 is an equilateral triangle, the first beam portion 13 may be disposed at the vertex of the equilateral triangle.

Also, for example, when the main leg portion 10 has a regular hexagon in cross section, the first beam portion 13 may be disposed at three vertices of the regular hexagon that are spaced apart from each other.

[First Embodiment]

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

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

That is, the sofa block 1 may be in a form including four main leg portions 10 extending from the center of a virtual tetrahedron toward each vertex of the tetrahedron.

According to the first embodiment, the cross-section (a surface cut in a plane perpendicular to the central axis of the leg portion) of the main leg portion 10 is substantially circular. And the main leg portion 10 is in the shape of a cone whose cross-section becomes smaller as it goes from the center of the sofa block to the end of the main leg portion 10. That is, the main leg portion 10 is substantially in the shape of a truncated cone.

For convenience of explanation, when the sofa block is placed on the ground among the four main legs, the main leg that faces the top is called the first main leg, and the remaining main legs that are in contact with the ground are called the second main leg and the third main leg, respectively. It is referred to as the leg part and the fourth main leg part. However, they are referred to this way for convenience of explanation, and in reality, there is no difference in the shapes of the first to fourth main legs.

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

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

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

The three radial parts 40 extend radially on a plane.

The cross-sectional shape of the radial part 40 cut in a plane perpendicular to the direction in which the radial part 40 extends is such that the direction perpendicular to the virtual central axis of the main leg part 10 is the main leg part 10. It may have a rectangular shape that is longer than the direction parallel to the virtual central axis of . To put it simply, the cross section of the radial portion 40 may have a flat rectangular shape. Of course, as mentioned earlier, the cross-sectional shape is not necessarily limited to this.

The sub-leg portion 30 further includes a connecting portion 50 therebetween.

The connecting portion 50 may be disposed between the three radial portions 40, respectively. That is, the connecting portions 50 may also be provided three at 120 degree intervals. The connecting portion 50 is disposed between two neighboring radial portions 40 and connects the two neighboring radial portions 40. The radial portion 40 has its strength determined by the connecting portion 50. can be reinforced.

The length at which the connecting portion 50 extends radially from the center of the sub-leg portion 30 is smaller than the length at which the radial angle portion 40 extends radially from the center of the sub-leg portion 30. Accordingly, the radial angle portion 40 protrudes further in the centrifugal direction than the connecting portion 50 between them.

Referring to FIG. 3, the direction in which the radial angle portion 40 extends from the end of the main leg portion 10 is the direction in which the remaining three main leg portions 10 adjacent to the main leg portion 10 extend. It's the opposite direction. In other words, the azimuth of the direction in which the radial angle part 40 extends from the main leg part 10 based on the virtual central axis of the main leg part 10 is the virtual center of the main leg part 10. The direction is opposite to the azimuth of the direction in which the remaining three main leg parts 10 adjacent to the main leg part 10 extend from the main leg part 10 relative to the axis. Then, as shown in FIG. 5, one radial portion 40 of the sub-leg portion 30 provided at the ends of the second to fourth main leg portions comes into contact with the ground. This arranges the sofa block (1) slightly higher from the ground than when the two radial angle parts (40) are in contact with the ground. Therefore, the orientation of the radial angle portion 40 increases the porosity of the sofa block 1.

The sofa block (1) has a shape that protrudes in the centrifugal direction from the circumferential surface of the main leg portion (10) and is provided with a first beam portion (13) that extends along the longitudinal direction of the main leg portion (10). .

The first beam portion 13 may be Y-shaped. Specifically, the first beam portion 13 connects three neighboring main leg portions 10.

The first beam portion 13 protrudes in a centrifugal direction from the surface of the main leg portion 10, and extends from the point where all three neighboring main leg portions 10 meet at the center of the sofa block. It extends in a Y shape to the end of the leg portion 10. Accordingly, the first beam portion 13 is formed in a region where the first main leg portion, the second main leg portion, and the third main leg portion are adjacent to each other, and the first main leg portion, the second main leg portion, and the fourth main leg portion are adjacent to each other. The leg portions are formed in adjacent portions, the first main leg portion, the third main leg portion, and the fourth main leg portion are formed in adjacent portions, and the second main leg portion, the third main leg portion, and the fourth main leg portion are formed in adjacent portions. Absences may be formed in neighboring areas. In this way, four first beam units 13 may be provided.

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

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

In addition, for example, when the first main leg part receives an external force that bends toward the fourth main leg part, the first beam part 13 formed in the area adjacent to the first main leg part, the second main leg part, and the fourth main leg part. In the beam portion provided in the first main leg portion and the first beam portion 13 formed in adjacent areas of 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 has compressive force. Alternatively, it is subjected to a shear force. As described above, since the first beam portion 13 itself is made of concrete, the two first beam portions 13 greatly resist the external force that bends the first main leg portion. In addition, the two first beam parts 13 formed on the first main leg extend to the second main leg and the fourth main leg, respectively, and extend to the third main leg and the fourth main leg, A portion of the first beam portion 13 extending to the second main leg portion and the fourth main leg portion and a portion of the first beam portion 13 extending to the third main leg portion and the fourth main leg portion are It has the effect of supporting the two first beam parts (13) of the first main leg part.

Additionally, reinforcing bars may be placed inside the first beam portion 13 along its longitudinal direction. Then, for example, when the first main leg part receives an external force that bends 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. (13), the beam portion of the first main leg portion, and the beam portion of the second main leg portion among the first beam portions 13 provided in the first main leg portion, the third main leg portion, and the fourth main leg portion. Additionally, the first main leg resists the tensile force or shear force that occurs when the first main leg is bent toward the second and third main legs, thereby greatly resisting the external force that causes the first main leg to bend.

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

In addition, the sofa block (1) further includes a second beam portion (15). The second beam portion 15 is formed at an area where two adjacent main leg portions 10 meet in order to reinforce the base ends of the two adjacent main leg portions 10.

The second beam portion 15 protrudes in a centrifugal direction from the surface of the main leg portion 10, and has a certain length along the circumference of the portion where two neighboring main leg portions 10 meet at the center of the sofa block. It may extend from the center of the first beam portion 13 to the center of the adjacent first beam portion 13. In the tetrapod-shaped sofa block as in the first embodiment, six second beam parts 15 as above are provided.

If necessary, reinforcing bars may also be placed in the second beam portion 15.

Since the second beam portion 15 is formed along the area where the two neighboring main leg portions 10 come into contact at the center of the sofa block, as well shown in Figures 2 and 4, the three neighboring main leg portions 10 Centering on the area where the , the three parts of the Y-shaped first beam part 13 are arranged at 120-degree intervals, and the three second beam parts 15 are arranged at 120-degree intervals. This can be said to be in the same form as six beam parts arranged at 60-degree intervals around the area where the three neighboring main leg parts 10 meet.

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

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 such external force.

In this way, the first beam portion 13 and the second beam portion 15 of the first embodiment greatly reinforce the strength of the main leg portion 10, so that even if the cross section of the main leg portion 10 is reduced, the main leg portion 10 This prevents fracture from occurring. In addition, the first beam portion 13 and the second beam portion 15 provide rigidity to sufficiently resist stress generated in the main leg portion 10 due to the sub leg portion 30 receiving an external force. do.

In addition, the first beam portion 13 and the second beam portion 15 provide significant curvature to the smooth surface of the tetrapod, thereby greatly increasing the sofa effect. Additionally, this shape provides an excellent habitat for the marine ecosystem.

In the first embodiment, the cross-sectional shape of the first beam portion 13 and the second beam portion 15 is illustrated to be rectangular. However, as explained several times, this is only an example and the cross-sectional shape may vary.

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

To one sub-leg portion 30, three first beam portions 13 are connected at intervals of 120 degrees.

According to the first embodiment, the first beam portion 13 is connected to the radial angle portion 40. Accordingly, the radial angle portion 40 that protrudes further outward than the connecting portion 50 in the radial direction can be supported more stably.

The sub-leg portion 30 is a corner surface beam portion that protrudes from the surface of the radial angle portion 40 and extends in a Y shape from the center of the sub-leg portion 30 to the ends of the three radial angle portions 40. 43) is provided.

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

Accordingly, the angle surface beam portion 43 and the connection surface beam portion 53 can be said to be in the form of six radially extending sections at 60-degree intervals, which are centered around the area where the three neighboring main leg portions 10 described above meet. It has the same form as 6 beam parts arranged at 60-degree intervals. Accordingly, the each part surface beam part 43 and the connection surface beam part 53 have similar strength reinforcement, sofa ability, and porosity improvement as the first beam part 13 and the second beam part 15, and provide a marine ecosystem habitat space, etc. effect can be achieved.

Likewise, reinforcing bars may also be placed in the corner surface beam portion 43 and the connection surface beam portion 53, if necessary.

Then, for example, when one of the radial angle parts 40 receives an external force and the corner surface beam part 43 of the radial angle part 40 receives a compressive or shear force, this compressive force or shear force is applied to the remaining two radial angle parts 40. It can be further supported by the compression resistance of the connection surface beam portion 53 of each surface beam portion 43 and the connection portion 50 provided between them, and the tension of the connection surface beam portion 53 of the remaining two connection portions 50 Alternatively, it may be further supported by shear resistance.

The reinforcing bars placed in each surface beam portion 43 and the connecting surface beam portion 53 may be connected to the reinforcing bars of the first beam portion 13, thereby ensuring higher strength.

The cross sections of each surface beam portion 43 and the connection surface beam portion 53 are square.

The corner surface beam portion 43 and the connecting portion surface beam portion 53 can increase the surface curvature of the sub-leg portion 30, thereby improving the sofa effect. Additionally, it becomes an excellent habitat for the marine ecosystem.

On the other hand, although not directly explained in explaining the embodiment, a chamfer can be added to prevent the sharp edge of the sofa block from breaking and to eliminate sharpness, and to reinforce the cross section of the deep edge (corner of the structure) and facilitate Of course, haunches can be formed for demolding the form.

[Second Embodiment]

Hereinafter, with reference to FIGS. 6 to 10, a second embodiment of the sofa block according to the present invention will be described. In explaining the second embodiment, the differences from the first embodiment will be mainly explained. Therefore, even if not directly mentioned in explaining the second embodiment, such matters can be fully understood from the description of other embodiments, such as the first embodiment.

In contrast to the first embodiment, the sofa block of the second embodiment further includes a corner beam section 45 on the back side of the radial corner section 40 of the sub-leg section 30. The cross section of each side beam portion 45 is rectangular.

The angle back beam portion 45 protrudes from the back surface of the radial angle portion 40 and extends in a Y shape from the center of the sub-leg portion 30 to the ends of the three radial angle portions 40. Since the back surface of the sub-leg portion 30 is connected to the end of the main leg portion 10, the centripetal end of each back beam portion 45 is connected to the peripheral surface of the main leg portion 10. achieve

For example, when one of the radial angle sections 40 receives an external force and the corner surface beam section 43 of the corresponding radial section 40 receives a compressive or shear force, the tension or tension of the corner surface beam section 45 of the corresponding radial section 40 The shear resistance supports the radial angle portion 40 so that the radial angle portion 40 is not deformed or damaged.

In particular, since the angle beam portion 45 is connected to the first beam portion 13, the radial angle portion 40 extending long in the radial direction is supported more firmly.

In addition, the angle back beam portion 45 can increase the curvature of the back surface of the sub leg portion 30, thereby improving the sofa effect.

The portion that extends further in the centrifugal direction than the end of (10) is connected to the main leg portion (10) through the connecting back beam portion (55). Accordingly, the connection back beam section 55 further reinforces the connection strength between the connection section 50 of the sub-leg section 30 and the main leg section 10.

The three corner back beam parts 45 and the three connection back beam parts 55 provided on one sub-leg part 30 may be arranged radially at intervals of 60 degrees. Accordingly, not only can the strength reinforcement effect be further increased, but also the curvature of the back surface of the sub-leg portion 30 can be increased to improve the sofa effect.

In other words, the azimuth of the direction in which the radial angle part 40 extends from the main leg part 10 based on the virtual central axis of the main leg part 10 is the virtual center of the main leg part 10. It corresponds to the azimuth of the direction in which the remaining three main leg parts 10 adjacent to the main leg part 10 extend from the main leg part 10 based on the axis.

Then, as shown in FIG. 20, the two radial angle portions 40 of the sub-leg portion 30 provided at the ends of the second to fourth main leg portions come into contact with the ground.

[Embodiment 7]

Hereinafter, with reference to FIGS. 31 to 35, a seventh embodiment of the sofa block according to the present invention will be described. Matters that are not directly explained in the seventh embodiment can be fully understood from descriptions of other embodiments regarding the relevant content.

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

Compared to the first embodiment, the sofa block of the seventh embodiment omits the second beam portion 15 and is further provided with a third beam portion 17.

The sofa block (1) has a shape that protrudes in the centrifugal direction from the circumferential surface of the main leg portion (10), and includes a first beam portion (13) and a third beam portion (13) extending along the longitudinal direction of the main leg portion (10). It is provided with a beam portion (17).

The first beam portion 13 may be Y-shaped. Specifically, the first beam portion 13 connects three neighboring main leg portions 10.

The first beam portion 13 protrudes in a centrifugal direction from the surface of the main leg portion 10, and extends from the point where all three neighboring main leg portions 10 meet at the center of the sofa block. It extends in a Y shape to the end of the leg portion 10. Accordingly, the first beam portion 13 is formed in a region where the first main leg portion, the second main leg portion, and the third main leg portion are adjacent to each other, and the first main leg portion, the second main leg portion, and the fourth main leg portion are adjacent to each other. The leg portions are formed in adjacent portions, the first main leg portion, the third main leg portion, and the fourth main leg portion are formed in adjacent portions, and the second main leg portion, the third main leg portion, and the fourth main leg portion are formed in adjacent portions. Absences may be formed in neighboring areas. In this way, four first beam units 13 may be provided.

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

The third beam portion 17 protrudes in a centrifugal direction from the surface of the main leg portion 10, and extends from the point where two neighboring main leg portions 10 meet at the center of the sofa block. It extends in an I-shape to the end of the part 10. Accordingly, the third beam portion 17 is adjacent to the first main leg portion and the second main leg portion, a portion adjacent to the first main leg portion and the third main leg portion, and a portion adjacent to the first main leg portion and the fourth main leg portion. The area where the legs are adjacent, the area where the 2nd main leg and the 3rd main leg are adjacent, the area where the 2nd main leg and the 4th main leg are adjacent, and the area where the 3rd main leg and the 4th main leg are out. may form in the area.

The first beam portion 13 can further secure the strength of the main leg portion 10 while reducing the cross-sectional area of the main leg portion 10, especially in the radial direction from the central axis of the main leg portion 10. By being placed at the furthest position, the bending rigidity of the main leg portion 10 is greatly reinforced. Since the first beam portion 13 itself is made of concrete, the first beam portion 13 can exhibit very high resistance to compressive force or shear force occurring along its longitudinal direction.

The third beam portion 17 can also secure the strength of the main leg portion 10 while reducing the cross-sectional area of the main leg portion 10. When the cross-sectional shape of the main leg portion 17 is circular or regular hexagonal, the third beam portion 17 is disposed at the position furthest from the central axis of the main leg portion 10 in the radial direction, thereby increasing the bending rigidity of the main leg portion 10. will be greatly strengthened. When the cross-sectional shape of the main leg portion 17 is an equilateral triangle, the third beam portion 17 is disposed at the second most distant position in the radial direction from the central axis of the main leg portion 10, thereby increasing the bending rigidity of the main leg portion 10. will be greatly strengthened.

(13), a third beam portion 17 formed in a region adjacent to the first main leg portion and the second main leg portion, and a third beam portion 17 formed in a region adjacent to the first main leg portion and the third main leg portion. In the beam portions provided in the first main leg portion are subjected to compressive force or shear force. As described above, since the first beam portion 13 and the third beam portion 17 themselves are made of concrete, the corresponding portion is the first main leg portion. The leg portion greatly resists the external force of bending. In addition, the first beam portion 13 and the third beam portion 17 formed on the first main leg extend to the second main leg portion and the third main leg portion, so that the second main leg portion and the third main leg portion The first beam portion 13 and the third beam portion 17 extending to the leg portion have the effect of supporting the first beam portion 13 and the third beam portion 17 portion of the first main leg portion.

Additionally, reinforcing bars may be placed inside the first beam portion 13 and/or the third beam portion 17 along the longitudinal direction. Then, the first beam portion 13 and/or the third beam portion 17 can resist tensile force and shear force.

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

The sofa block (1) of the present invention is further provided with a sub-leg part (30) having three radial angle parts at the end of the main leg part (10) of the sofa block (1). Therefore, as in the first embodiment, one of the three radial parts may contact the ground, or as in the tenth embodiment, two of the three radial parts may contact the ground.

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

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

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

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

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

The three radial angle parts of the sub-leg portion of the second main leg portion of the sofa block mounted so that the first main leg portion is mounted upward (downward) are adjacent to the three radial portions of the sofa block and the third main leg portion is mounted so that the first main leg portion is mounted 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 of Figures 60 and 62).

In addition, the three radial angle parts of the sub-leg portion of the second main leg portion of the sofa block on which the first main leg portion is mounted upward (downward) are adjacent to the three radial angle portions of the sofa block on which the first main leg portion is mounted downward (upward). It is interlocked with the radial part of the sub-leg part of the main leg part and the fourth main leg part (see part d in Figure 60).

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

Previously, the mounting form of FIGS. 56 to 62 was based on the B arrangement shown in FIG. 63 in which the first layer of the sofa block was installed. However, the method of mounting the sofa block of the present invention is not limited to this. For example, the sofa block may be mounted based on the A arrangement shown in Figure 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 transverse directions is tight even with the first layer of the A arrangement itself. In addition, as can be seen in Figure 64, which is a plan view, when mounting a sofa block, interlocking can be performed simultaneously with mounting by simply lowering the lifted sofa block. This interlocking is possible by neighboring sub-leg parts, and this interlocking is possible because the sub-leg parts extend radially on a plane substantially perpendicular to the central axis of the main leg part.

Figures 65 to 68 show a method of mounting a two-layer sofa block in a two-legged manner. Referring to this, the sub-leg portions provided on the two main legs that descend from the sofa block mounted on the second floor are interlocked with the beam portion provided on the main leg portion of the sofa block mounted on the first floor and the sub-leg portion of the sofa block mounted on the first floor. You can confirm that it can be done.

In this way, the sofa block of the present invention forms a sub-leg portion at the end of the main leg portion and makes the thickness of the main leg portion reinforced by the beam portions thinner, thereby increasing the porosity without losing the porosity and providing the sofa effect of the sofa block. and rigidity can be greatly increased.

In the marine structure of the embodiment, a two-layer structure is exemplified on a different single-layer form. However, by using the sofa block of the present invention, not only three-layer and four-layer structures are possible, but also various shapes for each floor or within one floor. Of course, it can be mounted in a two-legged form as shown in Figures 65 to 68, a one-legged form as shown in Figures 59 to 62, etc.) and combinations thereof.

In addition, the sofa block of the present invention can be mounted randomly and can also be used for repair and reinforcement of previously constructed tetrapod marine structures.

As described above, the present invention has been described with reference to the illustrative drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can occur. In addition, although the operational effects according to the configuration of the present invention were not explicitly described and explained in the above description of the embodiments of the present invention, it is natural that the predictable effects due to the configuration should also be recognized.

For example, among the shapes described above, the fact that the cross-sectional shape is square means that the cross-sectional shape is substantially square. In other words, if the corners of a square are chamfered, it can strictly be said to be an octagon, but since its actual effect has the effect of a square, it can actually be said to be a square. Also, for example, if both sides of a square have a slight inclination angle to facilitate demolding, this can strictly be called a trapezoid, but since the practical effect is that of a square, this can also be said to be a square in practice. will be.
