Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sofa block,

The present invention relates to a mold for a sofa block, and more particularly, to a mold for manufacturing a sofa block in which two tetrapods are formed in a shape similar to that of an east portion by sharing one corner, And a method of manufacturing a sofa block using a mold.

A sofa block is a block made of concrete mainly for the purpose of dispersing or dissipating the energy of the wave, and receiving a large wave of a breakwater or a revetment for the purpose of reducing the reflected wave.

In the conventional sofa block, four horn-shaped tetrapods are most commonly used, and pod locks, dolos, sealock, and the like, which have modified tetrapods, have been recently used. In particular, the tetrapods are covered with a single layer or a plurality of layers on the slope of the breakwaters, or a plurality of blocks are densely formed when a coastal erosion structure such as a submerged structure is built to form a single structure. The breakwaters or stream bottoms formed by laminating tetrapods disperse or dissipate the wave energy due to the gap space between adjacent tetrapods, the rugged shape of the tetrapod itself, and their intertwining.

The sofa block should have sufficient stability against wave power, sufficient structural strength against external force or self weight, easy to install and use, and adequate porosity when laminated to attenuate wave energy. Are required.

There are two layers of covering type and embankment type for the sofa block. There are two types of covering type: upright type and inclined type. In the case of hard type, There is a format.

The embankment type is not easy because it is easy to implement porosity and it is easy to install and easy to construct, but it is seen that huge concrete structures are piled up on the public.

On the other hand, the two-layer covering type is advantageous in that the sofa block is arranged squarely so that a large concrete structure, a sofa block is arranged, does not hurt the aesthetics of the surroundings. However, whenever a sofa block of tens of tons is mounted one by one, (Angle), which is difficult to construct.

In addition, when repairing or reinforcing a built-up detached-wall breakwater, it is difficult to apply the conventional modified sofa blocks because they are incompatible with the tetrapod. Therefore, it is necessary to use the tetrapod of the same standard as that of the existing tetrapod There was.

On the other hand, when a sofa block having a complicated structure is produced, it is difficult to place and compact the concrete while securing the view from the concrete pouring hole located at the ceiling of the pouring mold to the lower parts of the pouring hole. There is a problem in that when the work is performed in a lying down state, many bubbles are generated on the upper surface of the eastern portion, and the strength against the cylindrical portion of the cylindrical shape is lowered.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

[Shape of Sofa Block]

Fig. 1 is a perspective view of one embodiment of a sofa block according to the invention, Fig. 2 is a front view of the sofa block of Fig. 1, Fig. 3 is a top view of the sofa block of Fig. 1 and Fig. 4 is a side view of the sofa block of Fig. .

The sofa block according to the present invention is provided with an earthen portion 10 to be a trunk and has three leg portions 21 and 22 at both ends in the longitudinal direction of the trunk in a direction away from the center of the trunk.

As will be described later, the cross section of the east portion relative to the plane perpendicular to the central axis 1 of the above-mentioned cross section 10 and the cross section of each corner with respect to the plane perpendicular to the central axis 2 of the above- to be. At this time, the substantial diameter of the eccentric portion 10 and the substantial diameter of the angular portions 21 and 22 are defined as distances between two sides opposed to each other in a regular hexagonal cross-section. However, even if the actual diameter of the hexagonal section is determined in any manner, the relationship between the diameter of the eastern part and the diameter of each part (for example, the relational expressions described below) .

The eccentric portion 10 has a central axis 1 along the longitudinal direction. The length W of the east portion along the central axis 1 is determined by the length w1 of the central diameter face 11 provided at the central portion in the longitudinal direction and the length w1 of the cross sectional area gradually decreasing from both sides of the central diameter face toward both ends The sum of the lengths w2 of the oblique-diameter faces 12, that is, W = w1 + 2 x w2.

The diameter D of the central diameter face 11 is the largest. The angle (a) formed by the surface of the oblique-diameter surface with respect to the surface of the center-diameter surface is determined to be about 3 °? A? 11 °, as the oblique-diameter surface 12 is a form in which the substantial diameter gradually decreases as the distance from the center- . When the angle a formed by the surface of the inclined diameter surface is smaller than 3 DEG, the effect of forming the inclined diameter surface is hardly observed, and when the angle a formed by the inclined diameter surface is larger than 11 DEG, It is difficult to sufficiently secure the length w2 and the base of the corner portions 21 and 22 to be described later, that is, the diameter B of the maximum diameter portion can not be ensured. Therefore, when the angle formed by the surface of the inclined diameter surface is in the above range, the load is applied to the sofa block as a whole, and the diameter of the gradually decreasing diameter is gradually reduced toward both ends of the east portion, By further ensuring the protruding lengths of the leg portions 21 and 22, the sofa effect can be further enhanced.

(W1) in the longitudinal direction of the center axis of the central diameter surface of the above-mentioned portion and a length (w1) in the longitudinal direction of the central portion of the above- By distributing the length w2 in the longitudinal direction of the central axis of the oblique-diameter surface substantially the same, the outer surface of the east portion can have various angles, and the effect of dispersing waves can be further enhanced. This is an effect that can be enjoyed regardless of whether the sofa block of the present invention is erected by standing, mounted on a slope in an inclined direction, or placed on a slope in a contour direction.

The angular portions 21 and 22 of the present invention are formed such that the center axis 2 thereof is at an angle of 120 degrees with respect to the center axis of the east portion at one end portion of the central axis 1 of the same portion 10, Three first corner portions 21 and a central axis 2 thereof are formed at an angle of 120 degrees with respect to the center axis of the east portion at the other end of the center axis 1 of the east portion 10, And a second corner 22. Since the center axis 1 of the east portion and the center axis 2 of all six corner portions are at 120 degrees to each other, the corner portions extend in the direction away from the center axis 1 and the center point 15 of the east portion.

At this time, since the lengths of the central axes 2 of all the parts are equal to each other, the lengths of all the legs 21 and 22 coincide with each other. Also, the three first corner portions 21 are equally arranged at intervals of 120 degrees with respect to the center axis direction of the east portion, and the same is true for the three second corner portions 22. [

The first corner portion 21 and the second corner portion 22 are provided at positions mutually point symmetrical with respect to the center point 15 of the earthed portion 10. That is, referring to FIGS. 2 and 4, for example, the second corner 22 extending upward is provided at the other end corresponding to the first corner 21 extending downward from one end.

The edges of the legs 21 and 22 are chamfered or chamfered to prevent edges of the legs from being broken and to have a surface having normal lines in various directions to enhance the sofa effect.

The first angle portion and the second angle portion each have an inclined surface in which the substantial diameter gradually decreases toward the end portion. The inclination angle c formed by the inclined surface with respect to the central axis of the angle portion has a relationship of 4 ° ≤ c ≤ 10 ° Satisfies. If the angle of inclination is less than 4 degrees, the angular portions become substantially cylindrical, and the interlocking mount becomes difficult during the construction process. If the inclination angle is larger than 10 degrees, it is difficult to secure the diameter of each end portion, , Which may cause the sofa effect to deteriorate.

The substantial diameter D of the center diameter face of the east portion and the substantial diameter B of the maximum diameter portion of the corner satisfy a relation of 2 x B < 3 ^0.5 x D. This is a condition for allowing the base of three legs to come into contact with each other as shown at the time when three legs start to extend from the surface of the eastern part. In other words, according to these conditions, one corner is geometrically connected to the neighboring two corners and the same level uniformly, so that the external force applied to each corner is well dispersed, so that damage to each corner can be minimized. If the diameter of the base of the corner portion is excessively large, the area where the corner portions protruding from the east portion are overlapped with each other increases, so that the protruding length of the substantially corner portion decreases, leading to a reduction in the interlocking effect and a reduction in the sofa effect. On the other hand, if the diameter of the base of the corner portion is too small, each corner portion is individually connected to the east portion, so that each portion may be easily broken.

The present invention is characterized in that the substantial diameter D of the center diameter face of the east portion and the substantial diameter B of the maximum diameter portion 27 of the corner portion have the above- ) Portion of the hexagonal cross section of the square section of the square section meets at the center p near the center of the regular hexagonal section of the leg sections 21 and 22, (Vertex) portion (q). That is, the side of the square section of the square section that meets the corner (vertex) section of the regular hexagonal section of the east section meets the corner (vertex) section of the east section in the vicinity of the center p, (Q) of the side part of the square section of the square section is brought into contact with the angle (vertex) part of the corner section, and the variation of the east section which meets the corner section becomes "> ".

This results in a geometric shape that further enhances the sofa effect. That is, since the central portion of the side portion of the regular hexagon section of the eccentric portion 10 meets the angular portion (q) of the regular hexagonal section of the leg portions 21 and 22, the flow of water, which hits the surface of the eccentric portion, The flow of the water which is dispersed once again at the angle (vertex) portion q of the regular hexagon cross section of the leg portions 21 and 22 and dispersed once more, (Apex) portion (p) d of the regular hexagonal cross-section.

Next, when the sofa block is placed on the ground by one first corner portion and two second corner portions, the internal angle b between the ground and the central axis of the east portion satisfies the relationship of 8 ° b 15 ° . (A) having an inclined diameter surface with respect to the central diameter surface and an inner angle (a) formed by the central axis of the east portion and the ground when the sofa block is placed on the ground by the one first corner portion and the two second corner portions b) satisfies the relationship of 3 ° a a b 15 °.

In particular, when the condition of a &amp;le; b is satisfied, when the sofa block is laid down on the ground, the central axis 1 of the east portion 10 is raised in the upward direction, The outer surface of the waveguide 12 is also upwardly inclined at different angles with respect to the ground, thereby further enhancing the energy dispersion effect of the wave.

On the other hand, the catch grooves 40 are formed along the longitudinal direction of the legs on the outer side of the corner portions opposite to the positions where the leg portions 10 are arranged with respect to the leg portions 21, 22. Therefore, when the locking or breakwater is installed with the sofa block of the present invention, the function of the artificial reptile can be combined.

[Interlocking Structure of Sofa Block]

Hereinafter, a structure for allowing the sofa blocks of the present invention to be interlocked with respect to various forms will be described.

The length W of the central axis of the eccentric portion 10 and the substantial diameter B of the maximum diameter portion 27 of the leg portions 21 and 22 satisfy the relationship of 1.1 x B? W? 1.3 x B. This is a condition for allowing the eastern portion 10 of one sofa block to be covered by neighboring portions of the other sofa block. Simply put, the eastern portion of the sofa block and the adjacent portions of the sofa block, where the length of the east portion must be greater than the diameter of each portion, can be interlocked with each other. However, in the present invention, each of the other sofa blocks may be interlocked at various angles with respect to the east portion of one sofa block, and each of the other two sofa blocks may be provided at the east portion of one first sofa block In order to prevent simultaneous fitting in the longitudinal direction of one sofa block, W was determined within a range of 1.1 times and 1.3 times of B, respectively. By this dimensional relationship, as shown in FIG. 5, it can be seen that the eastern portion of one sofa block and the parts of the neighboring sofa blocks are interlocked with each other among the defective sofa blocks.

Next, the substantial diameter D of the central diameter face 11 of the eccentric portion 10 and the length L of the central axis 2 of the leg portions 21 and 22 are (4/3) ^0.5 x D < L . This is a condition for ensuring that the ends of the central axes of the two neighboring angles are located further outward than the centers of the eastern portions lying in contact with both of the two central axes. If this condition is not satisfied, It can not be surrounded by the eastern part and can not expect smooth interlocking.

That is, when the sofa block of the present invention has the above-mentioned geometric relationship, the moving part 10 has a geometric shape that can be seated between two neighboring corner parts, and the central diameter face of the east part is located between two neighboring parts The sofa blocks can be interlocked in various forms not only between the parts but also between each part and the east part so that the interlocking between the sofa blocks is excellent not only in the static but also in the dead area.

Next, the substantial diameter D of the central diameter face 11 of the eccentric portion 10, the length L of the central axis 2 of the leg portions 21 and 22, and the center axis of the eccentric portion 10 The length W of the wirings 1 is set to satisfy the relationship of (3/4) ^0.5 x L + 0.5 x D x 0.9 < 0.5 x L + W < (3/4) ^0.5 x L + 0.5 x D x 1.1 Respectively. This is a geometric relationship that enables interlocking between the two sofa blocks between the sofa block and the raised sofa block.

That is, when the sofa block is set up, the value of 0.5 × L + W corresponding to the sum of the height of the lower part and the height of the eastern part is smaller than the height of the lower part of the sofa block, (X) and the slope (y) of FIG. 6, if it is configured to be 0.9 times or more and 1.1 times or less the value of (3/4) ^0.5 x L + 0.5 x D corresponding to the sum of the heights It can be seen that the respective parts can be interlocked with each other between the sofa block laid down on the sea floor at the boundary surface of the slope surface and the sofa block laid on the first slope surface, z between the sofa block laid down at the interface of the slope and the sofa block standing at the end of the slope, the parts can be interlocked with each other.

If the value of 0.5 × L + W is less than 0.9 times the value of (3/4) ^0.5 × L + 0.5 × D, the distance between the legs at both ends in the longitudinal direction of the raised sofa block is short, If the value of 0.5 × L + W is not interlocked and the value of 0.5 × L + W is more than 1.1 times the value of (3/4) ^0.5 × L + 0.5 × D, the distance between the legs at both ends in the longitudinal direction of the sofa block is too far, It is not interlocked with each part of the sofa block which is laid down.

Since the sofa block of the present invention has the above-described geometric relationship, the sofa block that is laid down and the sofa block that is installed upright can be interlocked with each other, so that various types of mounting methods can be implemented.

Next, the length L of the center axis of the corner portion and the length W of the center axis of the east portion are 0.5 × L + 0.5 × W × sin 33.69 × 1.3 (3/16) ^0.5 × L × cos 33.69 ° Lt; / RTI &gt; 33.69 ° corresponds to the slope slope on the National Standard Specification with a slope of 1.5: 1 in the horizontal to vertical direction. The value of {0.5 × L + 0.5 × W} × sin 33.69 ° represents the horizontal distance from the point where the extension line of the center axis of the east section intersects the slope of the sofa block to the center of gravity of the sofa block when the sofa block is mounted on a slope of 33.69 °. (3/16) ^0.5 × L × cos 33.69 ° when the sofa block was mounted on a slope of 33.69 ° with two corner portions of three sides of the sofa block facing the sea floor Is a value indicating the horizontal distance from the point at which the extension line of the central axis of the east portion meets the slope to the support point of the two corner portions placed on the slope.

If the horizontal distance from the point at which the extension line of the center axis of the east section and the slope face meet to the center of gravity of the sofa block is greater than the horizontal distance from the point at which the extension line of the center axis of the east section meets the slope to the support point of the above- The sofa block can not be laid on a slope of 33.69 ° and is turned away. Therefore, the horizontal distance from the point where the extension line of the center axis of the east part meets the slope to the support point of the two corner parts placed on the slope is larger than the horizontal distance from the point where the extension line of the center axis and the slope meet, In the present invention, the construction stability is secured for upright mounting on the slope by making the height at least 1.3 times larger for stability of the installation. That is, according to the present invention, even when a sofa block is mounted on a slope having a slope of 1.5: 1, which is a standard specification standard, the center of gravity is low and is disposed close to the center, and a stable standing state can be maintained.

[Manufacturing method of sofa block]

Hereinafter, a method of manufacturing a sofa block using the form according to the first embodiment of FIG. 9 and a method of manufacturing the sofa block using the form according to the second embodiment will be described.

Since the general procedure to assemble the mold, to pour, to compact, to cure, to demold and clean the mold, and to replace the cured sofa block is not much different from the conventional sofa block manufacturing process, The description related to the technical idea of the present invention is not described in detail.

Referring to FIG. 9, a method of manufacturing a sofa block according to an embodiment of the present invention includes assembling the three east molds, the first corner molds, the second corner molds, and the six end molds in a standing state, The concrete is poured through the piercing hole (first casting step). In the first casting step, the concrete is poured to confirm that the concrete is poured down to a position lower than the height of the window provided at the second corner portion corresponding to the lower portion of the form.

Concrete pouring can be done by hopper, chute, pump car. It should be noted that the separation between the discharge port of the chute pump pipe and the installation surface should be less than 1.5m so that the material separation does not occur.

Then, the concrete of each part arranged below is squeezed through the window of the second corner disposed together with the first casting step or after the first casting step (first compaction step).

Compaction during casting is carried out to diffuse the concrete mixer into the corners of the casting mold to dissipate the unnecessary air contained in the concrete mixer and to make the concrete concrete. If the compaction is insufficient, there is a problem that deep bubbles are formed and strength is lowered. On the other hand, overcompensation causes detachment of the material, which may affect the strength, so it is necessary to set the compaction to an appropriate level.

A common internal vibrator (vibrator) can be used for such compaction. During the compaction, the bubbles of concrete are gathered near the shaft of the vibrator. Therefore, it is recommended to gradually remove the shaft from the concrete at the end of each corner of the sofa block. Particularly, since the tip of each corner is a part where a pile is easy to appear, it is preferable to perform a vibrator so that the concrete spreads widely at this part. Since the window of the present invention has a window, the compaction process of each corner can be easily carried out .

Next, in a state where the window of the second corner portion disposed at the lower portion is covered, the concrete is poured through the concrete pouring hole, and the concrete is poured to a position lower than the height of the window provided at the first corner portion disposed at the upper portion And pour concrete (second casting step).

Then, the concrete of each part disposed on the upper part is squeezed through the window of each part disposed at the upper part together with the second casting step or after the second casting step (second compaction step).
