Can be expressed as the sum of the lengths w2 of the inclined diameter surfaces 12, i.e., W = w1 + 2xw2.

The central diameter surface 11 has the largest substantial diameter D. The inclined diameter surface 12 has a shape in which the actual diameter gradually decreases away from the central diameter surface, and the angle (a) formed by the surface of the inclined diameter surface with respect to the surface of the central diameter surface is determined to be about 3 ° ≤ a ≤ 11 °. Can be. If the angle (a) of the surface of the inclined diameter surface is smaller than 3 °, the effect of forming the inclined diameter surface is hardly observed. If the angle (a) of the surface of the inclined diameter surface is larger than 11 °, It is difficult to secure the length w2 sufficiently, and it is also impossible to secure the base B of the corner portions 21 and 22 to be described later, that is, the diameter B of the largest diameter portion. Therefore, if 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 prevents the breakage of the eastern part 10, while the diameter is gradually reduced toward both ends of the eastern part to protrude outward from the eastern part. By further securing the protruding length of the corner portions 21 and 22, the sofa effect can be further enhanced.

In addition, the surface of the eastern part is not flat and has a slanted diameter surface in this way to have a plane having normals in different directions, and the length (w1) in the longitudinal direction of the central axis of the central diameter surface of the eastern part and the eastern part of the eastern part If the length w2 in the longitudinal direction of the central axis of the inclined diameter surface is substantially equally distributed, the outer surface of the eastern surface may have various angles to further increase the dispersion effect of the wave. This is an effect that can be enjoyed regardless of whether the sofa block of the present invention is mounted upright, laid down in the inclined direction of the slope and searched or laid down in the slope of the slope.

On the other hand, the corner portions 21 and 22 of the present invention, the central axis (2) at each end of the central axis (1) of the eastern part 10 at an angle of 120 degrees with respect to the central axis of the eastern part projecting outwardly Three first angled portions 21 and the central axis 2 are three protruding outward at an angle of 120 degrees with respect to the central axis of the eastern portion at the other end of the central axis 1 of the eastern portion 10. The second corner portion 22 is formed. Since the central axis 1 of the eastern part and the central axis 2 of all six leg parts form 120 degrees from each other, the corner parts extend in a direction away from the central axis 1 and the central point 15 of the eastern part.

At this time, the central axis (2) of all the corners are the same in length, so all the corners (21, 22) are the same in length. In addition, the three first corner portions 21 are equally disposed at 120-degree intervals when viewed in the direction of the central axis of the eastern part of the eastern part, and the same applies to the three second corner portions 22.

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

The circumference of the ends of the corners 21 and 22 is formed with a chamfer, that is, a chamfer to prevent the edges of the corners from being broken and further includes a surface having normals in various directions to enhance the sofa effect.

The first and second corner portions have an inclined surface of which the diameter decreases gradually toward the ends thereof, and the inclination angle c formed by the inclined surface with respect to the central axis of the corner portion has a relationship of 4 ° ≦ c ≦ 10 °. Satisfies. If the angle of inclination is less than 4 °, each part becomes a cylindrical shape, which makes the interlocking process difficult during the construction process. If the angle of inclination is greater than 10 °, it is difficult to secure the diameter of the end of each part. This may lower the sofa effect.

The substantial diameter D of the central diameter plane of the eastern part and the substantial diameter B of the largest diameter part of each part satisfy the relationship of 2xB < ^30.5xD . This is a condition that allows the bases of the three corners to come into contact with each other, as shown, when the three corners begin to extend from the eastern surface. That is, according to these conditions, one part can be geometrically connected to each other at the same level with two neighboring parts and the eastern part, and the external force exerted on each part is well distributed, thereby minimizing the breakage of each part. If the base diameter of each part is too large, there are many areas where the parts protruding from the eastern part overlap each other, and the actual protruding length of the parts is reduced, leading to a decrease in the interlocking effect and a sofa effect. On the other hand, if the diameter of the base of each part is too small, since each part is individually connected to the eastern part, there is a fear that each part is easily broken.

The present invention has a relationship between the substantial diameter (D) of the central diameter plane of the eastern part and the substantial diameter (B) of the largest diameter part (27) of each part, and the angle (vertex) of the regular hexagonal cross section of the eastern part (10). ) Part meets near the center of the side (p) of the regular hexagonal cross-section of the corners (21, 22), the central portion of the side of the regular hexagonal section of the eastern portion 10 of the regular hexagonal cross-section of the corners (21, 22) The angle (vertex) part (q) meets.

This is a geometric shape that further enhances the sofa effect. That is, since the central portion of the side portion of the regular hexagonal cross section of the eastern portion 10 meets the angle (vertical) portion q of the regular hexagonal cross sections of the corner portions 21 and 22, the water flows toward the eastern side and is dispersed toward each portion. Of the regular hexagonal cross-section of each of the sections 21, 22, it is divided again at the angular (vertical) part (q) again and distributed again. In the regular hexagonal cross section, it is divided into two parts at the angular part (p) d and distributed again.

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

In particular, if the condition of a ≤ b is satisfied, the central diameter plane 11 of the eastern part and the two inclined diameter planes of the eastern part 10 in the direction in which the central axis 1 of the eastern part 10 moves upward when the sofa block is laid on the ground are mounted. All the outer surfaces of (12) are also raised, but at different angles with respect to the ground, it is possible to further enhance the energy dissipation effect of the waves.

On the other hand, the outer groove 40 is formed along the longitudinal direction of each portion on the outer surface of the portion facing the position where the eastern portion 10 is disposed on the basis of the respective portions (21, 22). Therefore, the construction of a sleeper or breakwater with the sofa block of the present invention can combine the function of artificial reefs.

[Interlocking Structure of Sofa Block]

Hereinafter, a structure for allowing the sofa block of the present invention to be interlocked with each other in various forms and relationships will be described.

First, the length W of the central axis of the eastern part 10 and the substantial diameter B of the maximum diameter part 27 of each of the parts 21 and 22 satisfy a relationship of 1.1 × B ≦ W ≦ 1.3 × B. This is a condition that allows the eastern part 10 of one sofa block to surround neighboring parts of another sofa block. In short, the eastern part of the sofa block and the parts of the neighboring sofa block can be interlocked with each other when the length of the eastern part is larger than the diameter of each part. However, in the present invention, the parts of the other sofa block can be interlocked at various angles with respect to the east side of one sofa block, and the parts of the other two second sofa blocks on the east side of one first sofa block W was determined to be 1.1 times and 1.3 times B in order to prevent simultaneous insertion in the longitudinal direction of the east side of one sofa block. By this dimensional relationship, as shown in FIG. 5, it is possible to confirm a relationship in which interlocked parts of the sofa block and the eastern part of one sofa block are interlocked with each other.

Next, the substantial diameter D of the central diameter surface 11 of the eastern part 10 and the length L of the central axis 2 of each of the parts 21 and 22 are (4/3) ^0.5 × D <L To satisfy the relationship. This is a condition for the end of the central axis of two neighboring corners to be located outside the center of the eastern side which is placed in contact with both central axes. It does not enclose the eastern part, so smooth interlocking cannot be expected.

That is, when the sofa block of the present invention has the geometrical relationship as described above, the eastern portion 10 has a geometric shape that can be seated between two neighboring portions, and the eastern central diameter plane is adjacent between two neighboring portions. Since it has a structure that is stably seated and supported, the sofa blocks can be interlocked in various forms not only between each part but also between each part and the eastern part, so that the interlocking between the sofa blocks is excellent even in the static as well as in the turbulence.

Next, the substantial diameter D of the central diameter surface 11 of the eastern part 10, the length L of the central axis 2 of each of the parts 21 and 22, and the central axis of the eastern part 10 The length (W) of 1) has a relationship of {(3/4) ^0.5 × L + 0.5 × D} × 0.9 <0.5 × L + W <{(3/4) ^0.5 × L + 0.5 × D} × 1.1 To be satisfied. This is a geometric relationship that allows interlocking between the parts of the two sofa blocks even between the lying down sofa block and the standing sofa block.

That is, the value of 0.5 × L + W, which is the sum of the heights of the lower parts of the lower part and the eastern height when the sofa block is set up, is the height of the lower part and the eastern part of the lower part when the sofa block is laid down. When it is configured to be 0.9 times or more and 1.1 times or less of the value (3/4) ^0.5 × L + 0.5 × D, which is a value corresponding to the sum of the heights corresponding to the radius, the bottom surface x and the slope y of FIG. It can be seen that the parts of the sofa block lying on the sea floor and the sofa block erected on the first stage can be interlocked with each other, and likewise the slope (y) and the cross section of FIG. It can be seen that the parts can be interlocked with each other between the sofa block lying on the boundary surface of z) and the sofa block standing at the end of the slope.

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 parts at both ends of the eastern length of the built sofa block is short and If it 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 parts at both ends of the eastern side of the sofa block is too far Interlocking with each part of the lying down sofa block is prevented.

Since the sofa block of the present invention has the above-described geometrical relationship, the sofa block mounted on the floor and the sofa block mounted on the floor can be interlocked with each other, so that various types of mounting methods can be implemented.

Next, the length L of the central axis of each part and the length W of the central axis of the eastern part are {0.5 × L + 0.5 × W} × sin 33.69 ° × 1.3 <(3/16) ^0.5 × L × cos 33.69 ° Satisfies the relationship. 33.69 ° corresponds to the slope of the slope according to the national standard specification, where the slope of the slope is 1.5: 1 in the horizontal to vertical length. Also, the value of {0.5 × L + 0.5 × W} × sin 33.69 ° indicates the horizontal distance from the point where the eastern central axis meets the slope to the center of gravity of the sofa block when the sofa block is mounted on a slope of 33.69 °. Value, and (3/16) ^0.5 × L × cos 33.69 ° value indicates that two of the three sides of the sofa block face the bottom and are placed on a slope of 33.69 ° when the sofa block is mounted upright. It is a value indicating the horizontal distance from the point where the extension line of the eastern central axis meets the slope and the support point of the two corner parts placed on the slope.

If the horizontal distance from the point where the eastern central axis meets the slope to the center of gravity of the sofa block is farther than the horizontal distance from the point where the eastern central axis meets the slope to the slope of the support of the two legs placed on the slope, The sofa block cannot be placed on the slope of 33.69 ° and will fall. Therefore, at least, the horizontal distance from the point where the extension line and the slope of the eastern central axis meet to the support point of the two parts placed on the slope should be greater than the horizontal distance from the point where the extension line of the eastern central axis meets the slope to the center of gravity of the sofa block. In the present invention, the construction stability for the upright mounting on the slope by ensuring at least 1.3 times larger for mounting stability. That is, according to the present invention, even if the sofa block is mounted on a slope having a slope of 1.5: 1, which is a standard specification, the center of gravity is low and disposed close to the center, so that it can maintain a stable standing state.

That is, two second corners 22 placed on the bottom of the slope face the sea bottom and one second corner 22 placed on the bottom of the slope faces the top surface, but the second corner of the sofa block of n steps (2) It mounts so that one 2nd angle part which faces the top section surface of the 2nd angle parts 22 of the sofa block of n-1 stage may be placed between two 2nd angle parts which face the sea bottom. Thus, one first angle part facing the sea bottom of the first angle parts 21 of the n-step sofa blocks is disposed between two first angle parts of the first angle parts 21 of the n-step sofa block facing the cloth section. To be placed.

Next, the sofa block is placed on the surface covering the slope (y) and the cross section (z), and the second block 22 placed on the slope is placed on the immediately preceding end (n = 4). It is placed so as to surround one second corner portion 22, and the first end portion 21 is mounted on the cloth end surface. In this case, one second corner portion 22 positioned on an inclined side and disposed upward is disposed between the two first corner portions 21 of the sofa block placed at the front end thereof and interlocked.

Next, the sofa block is mounted on the ceiling end surface z, and two second corners 22 placed on the floor face the slope, and one second corner 22 placed on the floor faces the ceiling. Orient the sofa block to At this time, the two second corners 22 facing the slope are placed between the slope and the top end surface so as to surround one first angle part 21 placed on the top end surface of the mounted sofa block to interlock. Let this be done.

The above-described mounting method of the sofa block is a description of the part shown on the drawing of FIG. However, the sofa block should also be mounted on the side of the part shown on the drawing (ie, the direction through or through the paper of the drawing). According to the embodiment of the present invention, in the same end side to the side, by interlocking the sofa block in a direction complementary to the mounting direction of the sofa block can be interlocked even between the sofa blocks arranged in the side. .

Hereinafter, a mounting method different from the above mounting method will be described with reference to FIG. 7. First, a sandstone mound (i) having a bottom surface (x), a slope (y) and a cloth section (z) is constructed. Next, the intermediate coating material j is coated on the mound i. The slope of the slope formed by the intermediate covering j mounted on the slope may be about 33.69 degrees as in the standard specification.

Next, the sofa block is placed on the bottom of the sea floor (x) and the slope (y). At this time, two second corners 22 are placed on the floor toward the sea bottom, and one first corner 21 is placed on the floor toward the slope.

Next, the sofa block is laid on the n-stage of the slope, and the second block 22 is placed on the floor toward the sea bottom and one first corner 21 is placed on the floor toward the top surface. . At this time, the two second corner portions 22 placed on the floor toward the sea bottom in the n-stage sofa block have one first corner portion 21 placed on the floor toward the top end surface in the n-1 sofa block. Mount to wrap. Then, one second corner portion 22 protruding upward from the n-side sofa block toward the sea bottom is between the two first corner portions 21 protruding upward from the n-1 sofa block. Fitted and interlocked.

Next, the sofa block is mounted on the ceiling end surface z and mounted so that two second corners 22 placed on the floor face the slope and one second corner 22 placed on the floor faces the ceiling. Two second corners facing the slope are mounted so as to enclose one first corner placed on the ceiling section of the sofa block mounted between the slope and the ceiling section.

The above-described method for mounting the sofa block is a description of the part shown on the drawing of FIG. However, the sofa block should also be mounted on the side of the part shown on the drawing (ie, the direction through or through the paper of the drawing). According to the embodiment of the present invention, in the same end side to the side, by interlocking the sofa block in a direction complementary to the mounting direction of the sofa block can be interlocked even between the sofa blocks arranged in the side. .

Next, a method of mounting the sofa block illustrated in FIG. 8 will be described. First, a sandstone mound (i) having a bottom surface (x), a slope (y) and a cloth section (z) is constructed. Next, the intermediate coating material j is coated on the mound i. The slope of the slope formed by the intermediate covering j mounted on the slope may be about 33.69 degrees as in the standard specification.

At this time, two second corner portions of the second corner portions placed on the top of the cross-section face are arranged so that one corner portion is placed on the bottom side of the sofa block placed on the previous slope, and one of the second corner portions placed on the bottom of the cross-section face is placed. Interlocking can be implemented while arranging the sofa blocks to be closer to each other by mounting the two second corners so that the two corners are placed on the floor in the sofa block placed on the slope immediately before.

As described above, according to the mounting method to which the sofa block of the present invention is applied, it is possible to mount the sofa block by laying it in the inclined direction of the slope or by laying it in the direction of the contour line, and at the sea bottom, the slope and the cloth section, and the boundary thereof Not only can the sofa block be erected or laid on the same floor, but the sofa block can be erected or laid on the same floor so that it can respond appropriately to the wave tendency at the location of the breakwater. Can be mounted on the sofa block.

Meanwhile, according to the present invention, the weight and height (H; see FIG. 3) of one sofa block to be laid down can be designed to be equal to the weight and height of two tetrapods of the designed standard, respectively. According to this, mounting a single sofa block can have an effect equivalent to stacking two tetrapods, and the construction process can be made very simple. In addition, when repairing and / or reinforcing the breakwaters constructed with tetrapods, the weight and height (H) of one sofa block to be laid down are set to the weight and height of two tetrapods of a predesigned standard, respectively. By designing equally, repair and reinforcement work is possible because the specifications are compatible with each other, and the work can be simplified by mounting two tetrapods when mounting one sofa block.

<Partial formwork between parts formwork>

As described above, the partial formwork abuts each other's flanges. 23 to 25, flange grooves 81 are formed in both flanges in contact with each other. Flange grooves 81 respectively formed on two flanges in contact with each other are provided at positions corresponding to each other. The plurality of flange grooves 81 may be formed at predetermined intervals along the longitudinal direction of the flange.

A bolt support member 82 is installed on one of the two flanges facing each other. The bolt support member 82 may be installed in pairs with the flange groove 81 therebetween. The bolt support member 82 may be installed for each flange groove 81.

The ring portion 841 of the bolt 84 of the eye bolt type is accommodated between the pair of bolt support members 82. In the state where the ring portion 841 is accommodated, a bolt support shaft 83 is installed through the pair of bolt support members 82. The bolt support shaft 83 penetrates through the ring portion 841. Therefore, the threaded portion 842 of the bolt 84 may rotate about the bolt support shaft 83.

In the state where the formwork is installed, the bolt support member 82 and the bolt 84 may be provided at a position where the bolt 84 can rotate in a direction in which the bolt 84 is separated from the flange groove 81 by the weight of the two flanges. have. Accordingly, the first flange 7311 of the second corner formwork 722, the second flange 7162 and the third flange 7103 of the first corner portion 712 of the eastern formwork 710, and the first corner formwork 721. The bolt support member 82 and the bolt 84 may be provided at the third flange 7213.

On the other hand, the first end surface formwork 731 and the second end surface formwork 732 are large movements during form assembly and removal. Therefore, when the bolt 84 is installed in the first end face formwork 731 and the second end face formwork 732, the bolt may be damaged or the worker may be injured by the bolt. Accordingly, the bolt support member 82 and the bolt 84 may be provided at the third flange 7103 of the second corner portion 713 of the eastern formwork 710.

On the other hand, when the two flanges which are in contact with each other in the state where the formwork is installed are in a position where the bolt does not rotate by gravity, the bolt support member 82 and the bolt 84 may be provided on either of the two flanges. For example, the first flange 7101 of the eastern portion 711 of the eastern formwork 710 corresponds to this. Further, even when both flanges are rotated in the same direction by gravity in the state where the formwork is installed, either of the two flanges may be provided with the bolt support member 82 and the bolt 84. For example, the first flange 7101 of the second corner portion 713 of the eastern formwork 710 corresponds to this. Thus, the first flange 7101 of the eastern form 710 of the eastern formwork 710 and the first flange 7101 of the second corner portion 713 of the eastern formwork 710 are left and right sides of the eastern formwork 710. To be installed on either side. Then, in fastening the three eastern formwork which is identical to each other, all can be treated identically. That is, the installation position and order of three eastern formwork may be arbitrarily made.

The hook handle 754 includes a handle 7541 that can be gripped by an operator, and a cantilever hook 7702 fixed to the second support 753. The cantilever hook 7702 has a cantilever structure extending in an arc direction about an axis of rotation of the hook handle 754. The tip portion of the cantilever hook 7702 is deformed well when caught by the second support portion 753, but the amount of deformation decreases toward the proximal end of the cantilever hook 7542. Therefore, the deeper the cantilever hook 7702 is inserted into the second support portion 753, the closer the hinge door is to the die outer surface. Opening the hinged door of the window structure can see the interior space of the formwork.

The partial formwork can be easily lifted and demolded using the circular lifting hole 718 and the long hole-shaped demolding hole 718 provided in the rib 717.

[Production method of sofa block]

Hereinafter, a method of manufacturing a sofa block using formwork according to an embodiment.

The general procedure of assembling the formwork, placing and compacting, curing, demoulding and cleaning the formwork, and displacing and repositioning the cured sofa block are not significantly different from the manufacturing process of the existing sofa block. This will not be described in detail, but will be described with respect to the technical spirit of the present invention.

First, the concrete is poured through the concrete pouring hole 77 (first pouring step). In the first pouring step, the concrete is poured while confirming that the concrete is poured to a position lower than the height of the window provided in the corresponding portion of the second corner portion disposed under the formwork.

Concrete pouring can use a hopper, chute, and a pump car. It should be noted that free fall from the outlet of the chute pump pipe to the pour surface should be, for example, 1.5 m or less to prevent material separation.

Then, the concrete of the second corner portion is compacted through the window of the second corner portion disposed below or after the first pouring stage.

Compaction during pour is carried out to spread the ready-mixed concrete into the corners of the formwork to dissipate unnecessary air contained in the ready-mixed concrete and make dense concrete. If there is a lack of compaction, there is a problem that the size of the deep bubbles are falling and the strength is reduced. On the contrary, excessive compaction may cause material to separate and affect strength, so it is necessary to make the compaction at an appropriate level.

For this compaction, a general internal vibrator (vibrator) can be used. During the compaction, the bubbles of concrete collect near the shaft of the vibrator, so it is better to slowly remove the shaft from the front end of the sofa block. Particularly, the tip of each part is a part that is easy to appear, so it is good to perform the vibrator so that the concrete spreads widely enough. Since the formwork of the present invention has a window, it is easy to secure the view and accessibility through the compaction process of each part. Can be done.

Next, in the state covering the window of the second corner portion disposed in the lower portion, while placing concrete through the concrete pouring hole, the concrete is to be poured to a position lower than the height of the window provided in the first corner portion disposed in the upper portion Placing concrete while confirming (second pouring step).

The concrete of the first corner portion is compacted through the window of the corner portion disposed in the upper portion together with the second pouring stage or after the second pouring stage (second compaction stage).

Before and after the compaction step, a sparging step of inserting a thin, long bar-shaped spacing bar between the formwork and the concrete may be further performed.

Next, in the state of covering the window of the first corner portion, while pouring concrete through the concrete pouring hole 77, the concrete is poured to confirm that all the concrete to be poured up to the ceiling (pouring step 3) .

When the casting is finished, choose the Temple of Heaven. The top selection is performed on feminine concrete after the concrete has stabilized after pouring. We push water for woman by choosing the temple of heaven and drive water and air which are easy to gather to taper part of temple of heaven.

After that, cure.

And the formwork is demoulded, which is achieved after the compressive strength of concrete is expressed above a predetermined level. Demoulding can be accomplished in approximately the reverse order of assembly, as follows.

1) The first end face formwork 731 and the second end face formwork 732 are opened (see FIG. 32).

2) demold the first corner formwork 721 on the eastern formwork 710 (see FIG. 33).

3) The module of the eastern formwork 710 and the first end face formwork 731 on the second corner formwork 722 is demolded.

4) Lift the sofa block by lifting it when the sofa block is completely cured.

5) Clean the formwork.

According to the formwork of the present invention as described above, it is easy to secure visibility and compaction for each part disposed at the lower part during concrete curing, so that concrete placement and compaction can be faithfully secured even for the weak part, thereby securing the strength of the sofa block. .

As described above, the present invention solves the problem of the vulnerable area of the sofa block, which may be vulnerable to compaction or air bubbles by performing pouring in multiple stages while utilizing the window in manufacturing the sofa block. Strength can be secured.

As described above, the present invention has been described with reference to the 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 modifications can be made.
