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 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.

Since the first beam part 11 and the second beam part 13 themselves are composed of concrete, the first beam part 11 and the second beam part 13 have a very large resistance to compressive force or shear failure generated along the longitudinal direction thereof. can perform

For example, when the main leg unit 10 receives an external force bending toward the body unit 20, the beam unit provided in the main leg unit receives a compressive force or shear force in the second beam unit 13. As described above, the second beam unit (13) Since itself is composed of concrete, the second beam part 13 greatly resists the external force bending the main leg part. In addition, since the second beam part 13 formed in the main leg part extends to the body part 20, the second beam part 13 provided in the body part 20 is the first beam part 11 part of the main leg part. has the effect of supporting At this time, if reinforcing bars are provided in the first beam part 11 , the first beam part 11 greatly resists the tensile force and shear force generated when the main leg part 10 is bent.

In addition, for example, when the main leg part 10 receives an external force that bends away from the body part 20, the first beam part extending to the main leg part 10 and the main leg part 10 connected adjacent thereto ( 11) receives a compressive force or shear force. As described above, since the first beam part 11 itself is made of concrete, the first beam part 11 extending to the neighboring main leg part 10 is the main leg part.

Therefore, although not directly mentioned in the description of the fourth embodiment, such matters may be fully understood from the description of other embodiments, for example, the first to third embodiments.

The sofa block 1 of the fourth embodiment is different from that of the first embodiment in that the radial extension distance of the connecting portion 50 reaches the end of the radial angle portion 40 . According to this, the sub-leg part 30 forms a hexagon.

The sofa block 1 of the fourth embodiment has the advantage that the shape of the sub-leg part 30 is simpler than that of the first embodiment, and thus the manufacture is easier.

[Example 5]

Hereinafter, a fifth embodiment of the sofa block according to the present invention will be described with reference to FIGS. 25 to 30 . In the description of the fifth embodiment, the differences from the fourth embodiment will be mainly described. Therefore, although not directly mentioned in the description of the fifth embodiment, such matters may be fully understood from the description of other embodiments, for example, the first to fourth embodiments.

The sofa block of the fifth embodiment is different from the fourth embodiment in the shape of the sub-leg part 30 .

The sub-leg part 30 includes three radial angle parts 40 extending radially from the imaginary central axis of the main leg part 10 defined along the extension direction of the main leg part 10 . .

In the fifth embodiment, the plurality of radial portions 40 extend radially on a plane.

The radial angle portion 40 is provided at intervals of approximately 112.5 degrees, 112.5 degrees, and 135 degrees in the circumferential direction. That is, it can be said that the three ends of the radial portion 40 form the vertices of an isosceles triangle.

Of the three radial parts 40, the radial part 40 that is spaced apart by the same angular distance from the other two radial parts 40, that is, the radial part 40 corresponding to the apex of an isosceles triangle extends in the direction in which the body part (20) is parallel to the extending direction, and the same direction as the extending direction of the body portion (20).

The cross-sectional shape of the radial angle part 40 is a rectangular shape in which the direction perpendicular to the imaginary central axis of the main leg part 10 is longer than the direction parallel to the imaginary central axis of the main leg part 10 . .

The connecting part 50 provided between the three radial parts 40 is disposed between the two adjacent radial parts 40 to connect the two adjacent radial parts 40 .

A length in which the inter-connection part 50 radially extends from the center of the sub-leg part 30 corresponds to a length in which the inter-connection part 50 and two adjacent radial parts 40 extend. That is, both sides of the end of the connecting portion 50 are connected to the end of the adjacent two rectangular portions (40). Accordingly, the shape of the outline connecting the end of the radial portion 40 and the end of the connecting portion 50 may be hexagonal.

As in the fourth embodiment, the wave block of the fifth embodiment is also provided with each part surface beam part 43 and each part back side beam part 45 on the front and back surfaces of the radiation angle part 40, and the surface of the connecting part 50 between them. A connection part surface beam part 53 and a connection part back surface beam part 55 are provided on the and the back surface, respectively. Radial inner ends of the back-beam section 45 and the connecting section back-beam section 55 are connected to the main leg section 10 .

On the surface of the sub-leg part 30 , the three corner surface beam portions 43 and the three corner back surface beam portions 45 both extend in a Y-shape. And the centers of these Y-shapes are substantially coincident.

The first beam part 11 and the second beam part 13 of the sofa block 1 of the fifth embodiment are connected to the connecting part 50 between them. In addition, the three connecting parts, the back beam part 55 is also connected to the one first beam part 11 and the two second beam parts 13, respectively.

The sofa block 1 of the fifth embodiment also has the advantage of being easier to manufacture because the shape of the sub-leg part 30 is simple, like the fourth embodiment.

In the fifth embodiment, in comparison with the fourth embodiment, it will be understood that the circumferential position of the radial angle portion 40 and the connecting portion 50 is exchanged with each other.

The drawings shown in relation to the first to fifth embodiments described above are only examples expressing the technical idea of the invention, and thus the technical idea of the present invention is not limited to the form shown in the drawings. For example, in the first to fifth embodiments, the height and shape of the first beam part 11 and the second beam part 13 protruding from the main leg part 10 and the body part 20 are the same as each other. However, since this is only an example, their height and shape may be different from each other. Similarly, although the height of the third beam part 15 is shown to be lower than the heights of the first beam part 11 and the second beam part 13, this is also only an example. Also, the fourth beam portion 17 has a shape in which the protrusion height gradually changes in the extending direction thereof. As such, the height and shape of the beam portion may be varied.

[Offshore structure for mounting sofa block]

The sofa block 1 of the present invention may be mounted on a slope. The sofa block 1 has horizontal leg parts 10-3 and 10-4 disposed at the rear with respect to the body 20, and vertical leg parts 10-1 and 10-2 disposed at the front. It is arranged so that the horizontal leg part is mounted on the slope at the upper part of the slope, and the vertical leg part can be mounted so as to be placed on another sofa block at the lower part of the slope.

Specifically, in the same stage (N stage), the horizontal leg parts 10-3 and 10-4 of the sofa block 1 are arranged in a line on the slope. And, at the upper end (N+1 stage), the horizontal leg portions 10-3 and 10-4 of the sofa block 1 are mounted on the slope, and the body portion 20 is directly lower than the lower end (N). Step) is spanned over the horizontal leg parts 10-3 and 10-4 of the two sofa blocks 1 adjacent to each other, and the vertical leg parts 10-1 and 10-2 are further lower than that (N-1 stage). ) is placed in the center of the two horizontal leg parts (10-3, 10-4).

Referring to FIG. 32 , the sub-leg part 30 of the vertical upper leg part 10-1 extends outward in a radial direction from an end of the vertical upper leg part 10-1. Accordingly, the back surface of the sub-leg part 30 is prevented from overtaking.

Also, referring to FIG. 33 , the sub-leg part 30 of the horizontal leg parts 10-3 and 10-4 allows the horizontal leg parts 10-3 and 10-4 to slightly float on the slope. Accordingly, while preventing the loss of the covered stone of the slope, even when a rip current occurs, the rip current can communicate through a slight gap between the covered stone and the sub-leg part 30, so that the sofa block 1 is moved. It has the effect of not being swept away by the flow.

Also, as shown in FIG. 33, the two sub-leg parts 30 of the two adjacent horizontal leg parts 10-3 and 10-4 of the two neighboring sofa blocks are located at the upper end than that, as shown in FIG. The first beam part 11, the second beam part 13, the third beam part 15 and/or the fourth formed in the horizontal lower leg part 10-2 and the body part 20 of the mounted sofa block 1) It interferes with the beam unit 17 and is interlocked.

In addition, as shown in FIG. 32, the surface beam parts 43 and 53 of the sub-leg part 30 of the vertical lower leg part 10-2 of the sofa block 1 of the upper stage (N+1 stage) are more The second beam part 13, the third beam part 15 and the second beam part 13 provided at the connection part of the two horizontal leg parts 10-3 and 10-4 of the two-stage lower end (N-1 stage) and the body part 20 are It comes into contact with the 4 beams 17, and the gap between these beams serves as a shelter for species such as fry and sea cucumbers, especially as habitats for marine ecosystems.

The sofa block of the present invention may be mounted in a static manner other than this static method, as well as in a difficult way. It can also be used for repair and reinforcement of pre-constructed so-called "Sirak" or "Dolos" offshore structures.

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, although the effects according to 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.
