Description

Sofa block {WAVE DISSIPATION BLOCK}

The present invention relates to a sofa block, and to a sofa block that can be manufactured in a large tonnage class, is easy to manufacture, is easy to mount, and has high stability after mounting.

Sofa blocks are structures that dissipate the energy of waves and waves by being mounted on slopes such as breakwaters. Various sofa blocks called "Tetrapod", "Dolos", "Sea Rock", "Dimple", etc. are being constructed on sites that have their own advantages.

Republic of Korea Patent Publication No. 1400283 shows a shape of a sofa block called "Dolos II". However, the sofa block has a problem in that the body is cut off because the shear surface of the body is small, compared to a pair of leg portions respectively present at both ends of the body in the longitudinal direction.

In addition, the sofa block has a flat shape with corners extending from the end of the body to both sides. Accordingly, when the sofa block is mounted on the slope, the corners extending horizontally are in close contact with the slope. That is, the sofa block does not have a passage through which seawater can flow between the slope and each part, and thus receives a great pressure in the downward direction of the slope when the wave is released. However, since the center of gravity of the sofa block is at the center of the body in the longitudinal direction, the center of gravity of the sofa block mounted on the upper end of the slope is located on the horizontal leg portion of the sofa block mounted at the lower end thereof. Therefore, it is the cause of the displacement of the position where the sofa block is mounted in the process of releasing the wave.

In addition, since the horizontal leg portion at the rear of the body extends flat, when the sofa block is mounted, the rear portion of the sofa block is in close contact with the slope, while the front portion is placed on the upper portion of the sofa block at the lower end and lifted considerably. There is a problem in that the vertical angle in front of the sofa block is arranged in a shape that is quite lie down in the direction of the slope, so that an overpass occurs.

[Shape of sofa block]

Hereinafter, the shape of the sofa block will be described with reference to FIGS. 1 to 6.

The sofa block (1) of the embodiment includes a body (2) extending in the front and rear direction, a pair of rear end inclined portions (3) extending in both sides from the rear end of the body (2), and the body (2) ), and a shear downward angle portion 5 extending downward from the front end of the body 2, and an intermediate upward angle portion 4 extending upward from the central portion (central portion biased toward the front) of the body 2.

<body>

The body 2 substantially forms a form of a regular octagonal column. The upper surface of the regular octagonal cross section of the body 2 faces upward, the lower face faces downward, and both sides are aligned to face both sides. That is, the eight sides of a regular octagonal cross section are at 12 o'clock, 1:30 o'clock, 3 o'clock, 4:30 o'clock, 6 o'clock, and 7 o'clock when viewed from the front to the rear (see Fig. 3). Look at the 30-minute, 9 o'clock, and 10:30 directions.

One side of the front end 21 of the body 2 has an inclined surface for connection with the side at the 3 o'clock direction, and the other side has a side at 9 o'clock and an inclined surface for connection with the side at 9 o'clock. .

<Rear slope angle part>

On both sides of the rear end portion 22 of the body 2, a pair of rear end inclined angle portions 3 extend outwardly to both sides. The proximal end of one rear inclined angle part 3, that is, the olfactory base 30, is provided on the side of the body 2 in the direction of 1:30, the side at 3 o'clock, and the side at 4:30, and the other rear inclined angle part ( The olfactory base 30 of 3) is provided on the side of the body 2 at 7:30, 9 o'clock, and 10:30.

The rear end inclined angle portion 3 may be in the form of a regular octagonal cone tapered so that the cross section gradually narrows from the proximal end to the distal end.

The extension length of the rear end inclined angle portion 3 may be about 40% to 70% of the extension length of the body 2, more preferably 40% to 60%. In the examples, a form of about 50% is exemplified. As a result, stability can be ensured when the sofa block 1 is mounted. That is, a sufficient width between the two olfactory end faces 31 can be secured so that the sofa block 1 does not turn left and right and maintains a stable posture. In addition, this corresponds to a longer distance than the intermediate upward angle portion 4 or the shear downward angle portion 5 to be described later. Therefore, it is possible to secure the volume of the rear inclined angle portion 3 so that the center of gravity c can move to the rear of the body 2 as much as possible.

When viewed in the extending direction of the rear end inclined angle portion 3, the 12 o'clock and 6 o'clock sides of the 8 sides of the regular octagonal section are, respectively, of the 8 sides of the regular octagonal section of the body (2). It is connected to the 12 o'clock side and the 6 o'clock side. The side at 3 o'clock and the side at 9 o'clock of the eight sides of the regular octagonal cross section of the one rear-end inclined portion 3 are connected to the side at 3 o'clock of the eight sides of the regular octagonal cross section of the body 2. Of the eight sides of the regular octagonal cross section of the one rear end inclined part 3, the side toward 1:30 and the side toward 10:30 is 1:30 of the eight sides of the regular octagonal cross-section of the body (2). It is connected with the direction side. Of the eight sides of the regular octagonal cross section of the rear end inclined portion 3, the side toward 4:30 and the side toward 7:30 is 4:30 of the eight sides of the regular octagonal section of the body 2 It is connected with the direction side.

When viewed in the extension direction of the other rear-end inclined portion 3 (see Fig. 2), the 12 o'clock and 6 o'clock sides of the eight sides of the regular octagonal cross-section of the other rear-end inclined portion 3 are, respectively, Of the eight sides of the regular octagonal cross section of the body 2, it is connected to the 12 o'clock side and the 6 o'clock side. Of the eight sides of the regular octagonal cross section of the other rear end inclined portion 3, the 3 o'clock side and the 9 o'clock side are connected to the 9 o'clock side of the 8 sides of the regular octagonal cross section of the body 2. Of the eight sides of the regular octagonal section of the other rear end inclined portion 3, the side toward 1:30 and the side toward 10:30 is 11:30 of the eight sides of the regular octagonal section of the body (2). It is connected with the direction side. Of the eight sides of the regular octagonal section of the other rear end inclined part 3, the side in the direction of 4:30 and 7:30 of the eight sides of the regular octagonal section of the body 2 is 7:30 of the eight sides of the regular octagonal section of the body 2 It is connected with the direction side.

The upper portion of the rear end portion 22 of the body 2 is connected to the side in the direction of 10:30 of the one rear inclination angle portion 3 and the side in the direction of 1:30 of the other rear inclination angle portion 3, the It is connected to the 12 o'clock side of the body 2 by an inclined surface. Similarly, the lower portion of the rear end portion 22 of the body 2 is connected to the side at 7:30 of the one rear inclined angle portion 3 and the side in the 4:30 direction of the other rear inclined angle portion 3, It is connected to the 6 o'clock side of the body 2 by an inclined surface.

The rear end inclined angle portion 3 extends outwardly, extends slightly rearward, and extends slightly downwardly at the same time. Referring to FIG. 4, the rear end inclined angle portion 3 is inclined downward by a predetermined angle i with respect to the xy plane. Further, referring to FIG. 5, the rear end inclined angle portion 3 is inclined backward by a predetermined angle j with respect to the xz plane. That is, the rear end inclined angle portion 3 is obliquely downwardly downward and extends outward. This shape allows the center of gravity (c) of the sofa block 1 to move to the rear of the body 2 as much as possible, and to move to the lower part. Due to the lower chamfer surface 52 of the shear downward angle portion 5 to be described later, the volume of the shear downward angle portion 5 may be smaller than the volume of the intermediate upward angle portion 4, so that the center of gravity (c) has room to move upward. However, if the rear end inclined angle portion 3 is inclined downward as described above, the center of gravity c has an effect of compensating so that it does not rise.

The olfactory front end surface 31 of the rear inclined angle portion 3 faces the outer side and looks slightly rearward and downward at an angle.

When the sofa block 1 is mounted on the slope, the posture of the sofa block 1 is a state in which the front of the body 2 is slightly lifted than the rear of the body 2, as shown in FIG. 12. Therefore, if the rear end inclined angle portion 3 is obliquely downwardly downward and extends outward, in contrast to the case where it is simply obliquely inclined backward or downwardly inclined, as shown in Fig. 11, the rear of the body 2 is The end 22 is mounted with the most lifted position.

Both angles i and j are limited to 5 degrees or more and 25 degrees or less for stable mounting of the sofa block 1. The ratio between the two angles (i, j) is the rear end 22 of the body 2 from the slope considering the inclination angle of the slope and the angle at which the front of the sofa block 1 is lifted compared to the rear. Can be determined so that it can be lifted the most. For example, by a downward angle (i), the lower end of the olfactory end surface 31 may be located further downward by a predetermined distance dz than the lower end of the body 2 (see Fig. 4), and at the rearward angle j The rear end of the olfactory front end 31 can be located further rearward by a predetermined distance dy than the rear end 22 of the body 2 (see Fig. 5), and by adjusting this ratio, the body 2 It is possible to determine so that the rear end 22 of) can be lifted the most.

In this way, when the rear end portion 22 of the sofa block 1 is slightly lifted from the slope, the angle at which the front of the sofa block 1 is lifted can be reduced. (45) The tendency to lie down at an angle can be minimized, and the effect of preventing overpass can be further increased. In addition, since the rear end portion 22 of the sofa block 1 floats with a certain gap with the slope, it provides a passage through which seawater escapes in the process of translating, thereby reducing the pressure exerted on the sofa block 1 by seawater. This can be alleviated, and accordingly, the phenomenon of leaving the position where the sofa block 1 is mounted can be minimized.

Of course, a chamfer is formed between the rear end face 31 and the circumferential face of the rear inclined angle portion 3, and this is the same for the intermediate upward angle portion 4 and the shear downward angle portion 5 to be described later.

<Middle upper leg>

In the upper portion of the body 2, as shown in FIG. 2, an intermediate upward angle portion 4 is provided at a distance moved rearward by a predetermined distance e from the front end 21 of the body 2 . The intermediate upward angle portion 4 extends upwardly and obliquely to the front, at approximately the center of the upper portion of the body 2. The base end portion of the intermediate upward leg portion 4, that is, the depreciation base portion 40 is provided on the side of the body 2 at 12 o'clock, the side at 1:30 and the side at 11:30.

The intermediate upward angle portion 4 has an approximately regular octagonal cross section. As shown in FIG. 2, the upper front surface 45 of the intermediate upward leg portion 4 is spaced apart from the front end portion 21 of the body 2 by a predetermined distance e. The intermediate upward angle portion 4 extends upward in a form that is obliquely inclined forward. Accordingly, when the sofa block 1 is mounted on a slope, the angle at which the upper front surface 45 lies obliquely along the slope can be minimized.

As can be seen in Figs. 1, 2, and 5, the intermediate upper angle portion 4 is connected to the olfactory base portion 30 of the rear end angle portion 3. That is, the intermediate upward angle portion 4 and the rear end inclination angle portion 3 overlap each other in some sections in the front-rear direction as shown in FIG. 2. Then, as shown in FIG. 2, the rear end inclined angle portion 3 is included in the smallest front surface (S-S) that can be broken in the body (2) portion of the sofa block (1). That is, as above, as the intermediate upward angle portion 4 and the rear end slope angle portion 3 of the sofa block 1 of the embodiment overlap with each other in the front and rear direction, the front surface of the body 2 of the sofa block 1 It has the effect of greatly increasing the value. As a result, the embodiment has an effect of preventing the phenomenon that the body 2 of the sofa block 1 is broken.

The intermediate upward angle portion 4 may be in the shape of a regular octagonal cone tapered so that the cross section gradually narrows from the proximal end to the distal end.

When viewed in the extending direction of the intermediate upward leg portion 4 (see Fig. 5), the side at 6 o'clock (rear depreciation) and the side at 12 o'clock (depreciation front) out of the eight sides of a regular octagonal cross section, the body ( It is connected to the 12 o'clock side out of the 8 sides of the regular octagon section in 2). The 3 o'clock side and the 9 o'clock side of the 8 sides of the regular octagonal cross section of the intermediate upward leg portion 4 are the 9 o'clock side and the 3 o'clock side of the 8 sides of the regular octagonal cross section of the body 2, respectively. It is connected with the stool. Of the eight sides of the regular octagonal cross section of the intermediate upward leg portion 4, the side toward 1:30 and the side at 4:30 are 10:30 of the eight sides of the regular octagonal section of the body 2 It is connected with the stool. Of the eight sides of the regular octagonal cross section of the intermediate upward leg portion 4, the side toward 7:30 and the side at 10:30 is the direction of 1:30 of the eight sides of the regular octagonal section of the body 2 It is connected with the stool.

The upper portion of the front end portion 21 of the body 2 is treated as an inclined surface so as to be connected to the depreciation base portion 40 of the upper front surface 45.

The intermediate upward angle portion 4 is inclined to the front from the body 2 and extends upwardly. Thus, for example, the upper upper surface 45 may form a vertical surface with respect to the extending direction of the body 2, and the upper upper upper surface 44 may form a surface that is obliquely inclined forward. Accordingly, the upper end face 41 faces upward from the body 2 but faces the front slightly obliquely.

The extended length of the intermediate upward leg portion 4 may be about 30% to 60% of the extended length of the body 2, more preferably 30% to 45%. In the examples, a form of about 38% is exemplified. If the extension length of the intermediate upward leg portion 4 is longer than this, the center of gravity c moves upward to reduce stability, and if the extension length is shorter than this, the sofa effect is greatly reduced.

<Shear downward leg part>

In the lower portion of the front end of the body 2, a shear downward angle portion 5 extending obliquely downward from the lower portion of the body 2 to the front is provided. The front end of the front downward angle portion 5 is connected to the front end portion 21 of the body 2, and the lower leg rear surface 54 of the front downward angle portion 5 is provided with the rear slope angle portion 3 and a predetermined They are arranged spaced apart by a distance. A distance in which the lower leg rear surface 54 is spaced apart from the rear end inclined angle portion 3 by a predetermined distance is greater than the rearward movement distance e of the intermediate upward angle portion 4. That is, the shear downward angle portion 5 is disposed at the front end as much as possible. This minimizes the angle at which the front of the body 2 is lifted when the sofa block 1 is mounted, so that the connection part between the bottom surface of the body 2 and the lower leg rear surface 54 is located as far as possible.

The shear downward angle portion 5 may have a shape of a horn having an approximately regular octagonal cross section, gradually narrowing in cross section from the lower leg base portion 50 as the base end to the lower leg end surface 51 as the tip end.

The extension length of the shear downward angle portion 5 may be about 25% to 40% of the extension length of the body 2. If the extension length of the shear downward angle portion 5 is longer than this, the sofa effect may be deteriorated because the distance to the sofa block 1 mounted in the lower part of the second stage cannot be secured. If the extension length is shorter than this, the sofa effect decreases. It is difficult to be stably placed on the sofa block 1 mounted at the lower part of the first stage. The extended length of the shear downward angle portion 5 is shorter than that of the intermediate upward angle portion 4. Accordingly, the center of gravity (c) can be further moved rearward.

When viewed in the extending direction of the shear downward angle portion 5 (see Fig. 6), the 12 o'clock side and the 6 o'clock side (lower leg rear side) of the eight sides of the regular octagonal cross section are, respectively, of the body 2 It is connected to the front end 21 and the 6 o'clock side of the 8 sides of the regular octagonal cross section of the body 2. The 3 o'clock side and the 9 o'clock side of the 8 sides of the regular octagonal cross section of the front downward angle part 5 are the 3 o'clock side and the 9 o'clock side of the 8 sides of the regular octagonal cross section of the body 2, respectively. It is connected with the stool. Of the eight sides of the regular octagonal cross section of the shear downward leg portion 5, the side at 4:30 is connected to the side at 4:30 of the eight sides of the regular octagonal cross section of the body 2. Of the eight sides of the regular octagonal cross section of the front downward angle portion 5, the side at 7:30 is connected to the side at 7:30 of the eight sides of the regular octagonal cross section of the body 2. Of the eight sides of the regular octagonal cross section of the shear downward angle portion 5, the side at 1:30 is an inclined surface between the front end 21 of the body 2 and the side at 3 o'clock (this inclined surface is formed by a curved surface). Can be composed of two triangular surfaces) and connected. Of the eight sides of the regular octagonal cross section of the shear downward angle portion 5, the side at 10:30 is an inclined surface between the front end 21 of the body 2 and the side at 9 o'clock (this inclined surface is formed by a curved surface). Can be composed of two triangular surfaces) and connected.

2, the inclination angle (a) formed by the lower leg end surface 51 of the shear downward angle portion 5 with the xy plane may correspond to the inclination angle (a) formed by the upper angle end surface 41 with the xy plane. have. In addition, a portion where the extension surface of the lower leg end surface 51 of the shear downward angle portion 5 meets the xy plane and the portion where the extension surface of the upper angle end surface 41 meets the xy plane may substantially coincide with each other. The inclination angle (a) may be about 15 to 20 degrees. Preferably, the inclination angle (a) may be about 17.5 degrees. That is, the extension surface of the upper angle end face 41 and the extension face of the lower angle end face 51 are symmetric with respect to the xy plane which divides the body 2 into two vertically along the length direction. Accordingly, since the sofa block 1 of the embodiment maintains the symmetry of the shape to some extent, even when the sofa block 1 is difficult to load, the voids can be uniformly distributed.

Referring to FIG. 2, a lower chamfer surface 52 having a larger inclination angle b than the inclination angle a may be provided in front of the lower leg end surface 51. Referring to FIG. 5, the lower leg end surface 51 is provided in an area portion corresponding to three sides of an octagon, and the lower leg chamfer surface 52 is substantially in an area portion corresponding to the remaining five sides of an octagon. It may be a prepared form. The inclination angle (b) may be 40 degrees to 50 degrees. Preferably, the inclination angle (b) may be about 45 degrees.

The lower chamfer surface 52 functions and functions as follows.

First, the lower chamfer surface 52 cuts a portion corresponding to the frontmost portion of the shear downward angle portion 5 to reduce the volume of the frontmost portion of the shear downward angle portion 5. Accordingly, the center of gravity (c) of the sofa block (1) can be further moved to the rear.

Next, in the sofa block 1 of the embodiment, the intermediate upward angle portion 4 is located rearward by a predetermined distance e from the front end portion of the body 2. Therefore, if there is no lower chamfer surface 52, the shear downward angle portion 5 of the sofa block mounted at the upper end and the intermediate upward angle portion 4 of the sofa block mounted at the second stage lower end interfere, and the sofa block at the upper end There may be a phenomenon in which the sofa block at the lower end of the first stage is not well engaged with the rear sloped portion 3. In addition, even if interference is avoided, there is little space between the shear downward angle portion 5 of the sofa block at the upper end and the middle upward angle of the sofa block at the lower end of the second stage, reducing the sofa effect, and the shearing of the sofa block at the upper end. Since the downward angle portion 5 and the intermediate upward angle portion of the sofa block at the lower end of the second stage are connected along the slope direction, there is a concern that an overwhelming phenomenon may increase.

On the other hand, if the lower chamfer surface 52 is provided, sufficient space is secured between the shear downward angle part 5 of the sofa block at the upper end and the intermediate upward angle part of the sofa block at the lower end of the second stage, as shown in FIG. It can exert a sofa effect. In addition, as shown in Fig. 9, the height of the boundary between the lower chamfer surface 52 and the front end 21 of the sofa block at the upper end is greater than the upper end of the intermediate upper leg 4 of the sofa block at the lower end of the second stage. As shown in FIG. 12, the front end portion 21 forms a steep upward slope and the lower chamfer surface 52 forms a steep downward slope, as shown in FIG. 12, thereby further enhancing the sofa effect.

In addition, the lower leg chamfer surface 52 is of great help in preventing safety accidents in the manufacturing process of the sofa block 1. For example, as shown in Figure 7, the sofa block 1 of the embodiment, in order to simplify the finishing of the upper end surface 41 is installed in the form of the sofa block 1 in a horizontal position (HL) It can be produced by pouring and curing concrete. At this time, if the formwork 55 corresponding to the lower leg end surface 51 and the lower leg chamfer surface 52 is integrally manufactured, and the formwork 55 is opened and closed around the horizontal axis of the lower end, the formwork 55 is closed. In this state, it is possible to secure a working space by sufficiently securing an angle (a+b) made with the ground, so that the opening and closing operation is easy. In addition, even if the formwork 55 is suddenly opened wide because the formwork 55 is accidentally missed, the formwork surface corresponding to the lower angle chamfer surface of the formwork is at a predetermined angle with the ground even when the formwork surface corresponding to the lower leg end surface is in contact with the ground. Since it is floated at an inclined angle as much as (ba), it is possible to secure a space in which the worker may not be laid on the steel formwork 55 having a significant load.

A lifting groove 53 may be further provided on the lower chamfer surface 52.

The lower leg rear surface 54 forms an obtuse angle with the bottom surface of the body 2, so that when the sofa block is mounted, the rear end inclined portion 3 of the other sofa block 1 mounted below it is well enclosed. Can (see Fig. 9).

[Mounting of sofa block]

A method of mounting a sofa block according to an embodiment will be described with reference to FIGS. 8 to 12.

The lowermost end (the sofa block indicated in yellow in the drawing) is mounted so that the rear end inclined angle portion 3 of the sofa block 1 is disposed at the boundary between the slope and the sea floor. The sofa blocks are mounted so that the rear slope angle portion of one sofa block is aligned with the other rear slope slope angle portion of the other sofa block adjacent thereto.

In addition, the sofa blocks mounted on the slope have the rear slope angle portion mounted on the slope, and the body is a body between the one rear slope angle portion and the other rear slope slope portion adjacent to each other of the two adjacent sofa blocks mounted on the lower end thereof. Mount it so that it is raised. At this time, it is mounted so that the bottom surface and the lower leg rear surface of the body of the sofa block being mounted are placed in a form that surrounds the rear end inclined corners of the sofa blocks mounted at the lower end.

When the sofa blocks are mounted in this way, the rear slope of the sofa block mounted on the upper end is placed on the slope, and the body of the sofa block mounted on the upper end is placed on the rear slope of the two adjacent sofa blocks at the lower end of the first stage. And, the lower chamfer surface of the sofa block mounted on the upper end faces the upper leg rear surface of the sofa block at the lower end of the second stage, spaced apart.

According to the embodiment, since the center of gravity (c) of the sofa block has moved significantly backward, the center of gravity of the sofa block 1 at the upper end is of the sofa block 1 at the lower end, as shown in FIG. 12. The center of gravity of the sofa block (1) is in the upper part of the rear slope of the sofa block (1) at the lower end, so that the sofa block at the upper end is in the lower end of the sofa. You can maintain a stable posture by yourself while pressing the rear slope of the block well.

According to the above-described invention, the center of gravity of the sofa block is moved to the rear, so that the sofa block can be maintained stably mounted on the slope, and the degree of hearing in the front of the body is suppressed to reduce overwhelming and greatly increase the sofa effect, Since there is a gap between the sofa block and the slope, the pressure applied to the sofa block in the process of removing seawater is greatly reduced, and the body is sturdy, so no breakage occurs, and it is convenient to manufacture and can prevent safety accidents.

In addition, in the sofa block 1 of the embodiment, the intermediate upward angle portion 3 protrudes upward from an approximately central portion of the body 2 in the longitudinal direction, and the intermediate upward angle portion 3 and part of the body 2 The rear end inclined angle portion 3 which is disposed overlapping extends in both sides so as to face downwardly, and the front end angle portion 5 extends downward from the front end of the body 2 obliquely toward the front, while the lower chamfer surface 52 Since it is provided, it has the characteristic that it has a shape similar to a so-called "tetrapod" as a whole. That is, the sofa block 1 of the embodiment is also compatible with the "tetrapod". Therefore, unlike "Tetrapod" and "Chirak" and "Dolos", which are completely different in shape, they have the advantage that they can be applied to reinforcement construction of a tetrapod structure previously constructed a long time ago.

As described above with reference to the drawings illustrated for the present invention, the present invention is not limited by the embodiments and drawings disclosed in the present specification, and various by a person skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformations can be made. In addition, even if not explicitly described and described the operating effects according to the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effects by the configuration should also be recognized.
