Description

Formwork for sofa block and method of manufacturing sofa block using same

The present invention is a form similar to that of two tetrapods forming the eastern part by sharing one leg, and a specific shape of a formwork for manufacturing a sofa block in which three leg portions are provided at both ends, and a method of manufacturing a sofa block using the same It is about.

The sofa block is installed in a place that receives large waves from a breakwater or revetment for the purpose of dispersing or dissipating the energy of the wave and reducing the reflected wave, and it refers mainly to a block made of concrete.

As a conventional sofa block, tetrapods shaped like four horns are most commonly used, and pod locks, dolos, and sealocks, which are modified tetrapods, have also been widely used recently. In particular, the tetrapods are covered with a single layer or a double layer on the slope of the breakwater, or when a coastal erosion structure such as a submerged material is constructed, a plurality of tetrapods are densely formed to form a single structure. Breakwaters or river floors formed by laminating tetrapods disperse or dissipate wave energy due to the interstitial space between adjacent tetrapods, the uneven shape of the tetrapod itself, and their interlocking.

The sofa block should have sufficient stability against wave power, etc., should have sufficient structural strength against external force or its own weight, should be easy to lift and construct, and should be able to obtain an appropriate porosity when stacked to reduce wave energy, etc. The requirements of are required.

There are two-layered and non-removable types for mounting sofa blocks, and two-layered types include upright and inclined coating types, and the bulky type includes an upright shear surface covering type and inclined shear surface covering. There is a format.

Difficulty type is easy to implement porosity and is easy to install, so it has good constructability, but to the general public, it is not good because it is seen as a huge concrete structure piled up messy.

On the other hand, the two-story covering type is advantageous in that the sofa blocks are arranged in an orderly manner so that even if the sofa blocks, which is a huge concrete structure, are arranged, it is advantageous in that it does not spoil the surrounding beauty. There is a problem that construction is difficult in that it must be adjusted to the (angle).

In addition, when repairing or reinforcing the previously constructed tetrapod-covered breakwater, it is difficult to apply the existing modified sofa blocks because they are not compatible with the tetrapod, so it is inconvenient to use a tetrapod of the same standard as the existing tetrapod. There was a ship.

On the other hand, in the case of fabricating a sofa block with a complex structure, it is difficult to pour and compact while securing a view from the concrete pouring hole at the top of the formwork to the corners at the bottom, so there is a possibility that there is a risk of crushing at the tip of each part. When working in a lying state, there was a problem that the strength of the cylinder-shaped eastern part decreased due to the occurrence of many air bubbles on the upper surface of the eastern part.

In addition, as the formwork is divided into more parts to implement a complex structure, the number of formwork parts increases, making maintenance difficult and field construction difficult.

In particular, when the height of the formwork is high, it cannot be ruled out that there is a risk of serious injury to the operator or loss of life in the process of assembling or removing parts of the formwork.

The present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, only the present embodiment is intended to complete the disclosure of the present invention, and the scope of the invention to those of ordinary skill in the art. It is provided to inform you.

[소파블록의 형상][Shape of sofa block]

1 is a perspective view of an embodiment of a sofa block according to the present invention, FIG. 2 is a front view of the sofa block of FIG. 1, FIG. 3 is a plan view of the sofa block of FIG. 1, and FIG. 4 is a side view of the sofa block of FIG. .

The sofa block of the present invention has a structure in which a body portion 10 serving as a body is provided, and three

leg portions

21 and 22 are provided at both ends of the body in a longitudinal direction away from the center of the body.

As will be described later, the cross-section of the eastern part with respect to the plane perpendicular to the central axis 1 of the eastern part 10 and the cross-section of each part with respect to the plane perpendicular to the central axis 2 of the

corner parts

21 and 22 are all regular hexagons. to be. At this time, the actual diameter of the eastern part 10 and the actual diameter of each

part

21 and 22 are determined as the distance between two sides facing each other in a regular hexagonal cross section. However, even if the actual diameter of the regular hexagonal cross section is determined in any way, if the method of determining the diameter in the eastern part and the method of determining the diameter in each part coincide, the relationship between the diameter of the eastern part and the diameter of each part (e.g., relational formulas to be described later) is also understood. Can be.

The eastern part 10 has a central axis 1 along the longitudinal direction. The length (W) of the eastern part along the central axis (1) is the length (w1) of the central diameter surface (11) provided at the center portion in the longitudinal direction, and the cross-sectional area gradually decreases toward both ends from both sides of the central diameter surface It can be expressed as the sum of the lengths (w2) of the inclined diameter surface 12, that is, W = w1 + 2 × w2.

The center diameter surface 11 has the largest practical diameter D. The inclined diameter surface 12 is a shape whose actual diameter gradually decreases as it moves 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°. I can. If the angle (a) formed by the surface of the inclined diameter surface is less than 3°, the effect of forming the inclined diameter surface is hardly seen. If the angle (a) formed by the surface of the inclined diameter surface is greater than 11°, the It is difficult to sufficiently secure the length w2, and it is not possible to secure the base of each

part

21 and 22 to be described later, that is, the diameter B of the maximum diameter part. Therefore, if the angle formed by the surface of the inclined diameter surface is within the above range, a load is applied to the sofa block as a whole and prevents damage to the eastern part 10, while the diameter gradually decreases toward both ends of the eastern part and protrudes outward from the eastern part. By further securing the protruding length of the

corners

21 and 22, the sofa effect can be further increased.

In addition, the eastern surface is not flat and has an inclined diameter surface as described above, so that it is made of 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 If the length w2 of the central axis of the inclined diameter surface is substantially equally distributed, the outer surface of the eastern part forms various angles, thereby further enhancing the dispersion effect of waves. This is an effect that can be enjoyed regardless of whether the sofa block of the present invention is mounted upright, searched by lying down in an inclined direction of a slope, or laid down in a contour direction of a slope.

On the other hand, each part (21, 22) of the present invention, its central axis (2) at one end of the central axis (1) of the eastern part 10 forms an angle of 120 degrees with respect to the central axis of the eastern part, each protruding outward The three first leg portions 21 and their central axis 2 form an angle of 120 degrees with respect to the central axis of the eastern part from the other end of the central axis 1 of the eastern part 10, and each of the three It consists of a second leg 22. Since the central axis 1 of the eastern part and the central axis 2 of all six parts form 120 degrees to each other, the each part has a shape extending in a direction away from the central axis 1 and the central point 15 of the eastern part.

At this time, since the lengths of the central axes 2 of all the corners coincide with each other, all the

corners

21 and 22 have the same lengths. In addition, the three first leg portions 21 are evenly arranged at intervals of 120 degrees to each other when viewed in the direction of the central axis of the eastern portion of the eastern portion, and this is the same for the three second leg portions 22.

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

A chamfer, that is, a chamfer is formed around the ends of the

corner portions

21 and 22 to prevent breakage of the end edges of the corner portions, and a surface having normals in various directions is further provided to enhance the sofa effect.

The first leg and the second leg have an inclined surface in which the actual diameter gradually decreases toward the end, and the inclination angle (c) formed by the inclined surface with respect to the central axis of the leg is 4° ≤ c ≤ 10°. Satisfies. If the angle of inclination is less than 4°, the angle part becomes substantially cylindrical, making interlocking difficult during the construction process, and if the angle of inclination is greater than 10°, it is difficult to secure the diameter of the end of each part, so there is a limit to extending the angle part long. , As a result, there is a concern that the sofa effect may decrease.

The actual diameter (D) of the central diameter surface of the eastern portion and the actual diameter (B) of the maximum diameter portion of the corner portion satisfy the relationship of 2 x B <3 ^0.5 x D. This is a condition in which the bases of the three leg portions are brought into contact with each other as shown at the time when the three leg portions begin to extend from the eastern surface. That is, under these conditions, one leg is geometrically connected to each other at an equal level with the adjacent two leg portions and the eastern portion, so that the external force applied to each portion is well distributed, thereby minimizing the damage of each portion. When the diameter of the base of the leg portion is too large, there are many areas where the leg portions protruding from the eastern portion overlap each other, so that the length of the protrusion of the leg portion decreases, which leads to a reduction in the interlocking effect and the 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 possibility that the part is easily damaged.

In the present invention, while the actual diameter (D) of the central diameter surface of the eastern part and the actual diameter (B) of the maximum diameter portion 27 of the corner portion have the above-described relationship, each (vertex) of the regular hexagonal cross section of the eastern part 10 ) The part meets near the center (p) of the side of the regular hexagonal cross-sections of the corners (21, 22), and the central part of the side of the regular hexagonal cross-section of the eastern part (10) It meets the angle (vertex) part (q).

This becomes a geometric shape that further enhances the sofa effect. That is, the central portion of the side portion of the regular hexagonal cross section of the eastern part 10 meets the angle (vertex) portion (q) of the regular hexagonal cross-section of the

corners

21 and 22, so that the flow of water colliding with the eastern side and distributed toward the corners Of the regular hexagonal cross-sections of each part (21, 22), it is divided again at each (vertex) part (q) and is dispersed once more. Of the regular hexagonal cross section, it is divided again at each (vertex) part (p)d and dispersed once more.

Next, when the sofa block is placed on the ground by one first leg and two second leg 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 when the sofa block is placed on the ground by the inclination angle (a) of the inclined diameter surface with respect to the center diameter surface and the one first leg and two second leg portions, the inner angle formed by the central axis of the ground and the eastern part ( b) satisfies the relationship of 3° ≤ a ≤ b ≤ 15°.

In particular, if the condition of a ≤ b is satisfied, the central axis (1) of the eastern part 10 is upward when the sofa block is laid on the ground, and the central diameter surface 11 of the eastern part and the two inclined diameter surfaces of both sides thereof All the outer surfaces of (12) are also upward, but the energy dissipation effect of waves can be further increased by making them at different angles to the ground.

On the other hand, on the outer surface of the corner portion facing the position where the eastern portion 10 is disposed based on the

corner portions

21 and 22, a fishing groove 40 is formed along the length direction of the corner portion. Therefore, if the sofa block of the present invention is used to construct a submerged or breakwater, it can also have the function of an artificial reef.

[소파블록의 인터록킹 구조][Interlocking structure of sofa block]

Hereinafter, a structure in which the sofa blocks of the present invention can be interlocked with each other in relation to various shapes will be described.

First, the length (W) of the central axis of the eastern portion (10) and the actual diameter (B) of the maximum diameter portion (27) of the corner portions (21, 22) satisfies the relationship of 1.1×B≦W≦1.3×B. This is one condition in which the eastern part 10 of one sofa block can be wrapped around the neighboring parts of the other sofa block. To put it simply, 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 the part. However, in the present invention, each part of the other sofa block can be interlocked at various angles with respect to the eastern part of one sofa block, and the parts of the other two second sofa blocks are located at the eastern part of one first sofa block. In order not to be fitted in the longitudinal direction of the eastern part of one sofa block at the same time, W was determined within the range of 1.1 times and 1.3 times of B. According to this dimensional relationship, it is possible to confirm a relationship in which the eastern part of one sofa block and each part of the neighboring sofa block are interlocked with each other between the sofa blocks that are scattered as shown in FIG. 5.

Next, the actual diameter (D) of the central diameter surface (11) of the eastern part (10) and the length (L) of the central axis (2) of the corners (21, 22) are (4/3) ^0.5 × D <L To satisfy the relationship. This is a condition to ensure that the ends of the central axes of the two neighboring legs are located outside the center of the eastern portion, which is placed so as to be in contact with both the central axes.If these conditions are not satisfied, the two neighboring legs are sandwiched between them. As it cannot surround the eastern part, smooth interlocking cannot be expected.

That is, when the sofa block of the present invention has the above geometrical relationship, the eastern part 10 has a geometric shape that can be seated between two neighboring legs, and the central diameter surface of the eastern part is between two neighboring legs. Since the sofa blocks have a structure that is stably seated and supported on each other, the sofa blocks can be interlocked in various forms not only between each part, but also between each part and the eastern part, and interlocking between the sofa blocks is excellent in both static and difficult environments.

Next, the actual diameter (D) of the central diameter surface 11 of the eastern part 10, the length L of the central axis 2 of the each

part

21, 22, and the central axis of the eastern part 10 ( 1) The length (W) 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 I was satisfied. This is a geometrical relationship that enables interlocking between the parts of the two sofa blocks even between the laid sofa block and the standing sofa block.

In other words, when the sofa block is laid, the value of 0.5×L + W, which is the sum of the height of the lower parts and the height of the eastern part, is equal to the height of the lower part and the eastern part when the sofa block is laid down. If the value corresponding to the sum of the heights corresponding to the radius (3/4) is 0.9 times or more and 1.1 times or less of the value of ^0.5 × L + 0.5 × D, the sea floor (x) and slope (y) of FIG. 6 It can be seen that between the sofa block laid on the sea floor and mounted on the sea floor at the interface of and the sofa blocks erected at the first end of the slope, each part can be interlocked with each other. Likewise, the slope (y) and the top surface ( It can be seen that between the sofa block laid on the boundary of z) and the sofa block erected at the last 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 parts at both ends in the length direction of the eastern part of the erected sofa block is short If interlocking fails 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 in the length direction of the eastern part of the sofa block is too far and neighbors. Interlocking with each part of the laid sofa block is not possible.

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

Next, the length of the central axis of each part (L) and the length of the central axis of the eastern part (W) are {0.5×L + 0.5×W}×sin 33.69° × 1.3 <(3/16) ^0.5 × L × cos 33.69° Satisfy the relationship. 33.69° corresponds to the slope of the slope in the national standard specification where the slope of the slope is 1.5: 1 in the horizontal direction versus the vertical direction. In addition, the value of {0.5×L + 0.5×W}×sin 33.69° indicates the horizontal distance from the point where the extension line of the central axis of the eastern part meets the slope when the sofa block is mounted on a slope of 33.69° to the center of gravity of the sofa block. It is a value of (3/16) ^0.5 × L × cos 33.69° when the sofa block is erected and mounted so that two of the three corners of the sofa block face the sea floor and are placed on the slope of 33.69° It is a value representing the horizontal distance from the point where the extension line of the eastern central axis and the slope meet to the support points of the two legs placed on the slope.

If the horizontal distance from the point where the extension line of the eastern central axis and the slope meets to the center of gravity of the sofa block is greater than the horizontal distance from the point where the extension line of the eastern central axis and the slope meets the support points of the two legs placed on the slope, The sofa block cannot be placed on a slope of 33.69° and will fall over. Therefore, at least the horizontal distance from the point where the extension line of the eastern central axis meets the slope and the support points of the two legs placed on the slope must be greater than the horizontal distance from the point where the extension line of the eastern central axis and the slope meet to the center of gravity of the sofa block. And, in the present invention, by making it at least 1.3 times larger for mounting stability, construction stability for upright mounting on a slope was secured. 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 a stable erect state can be maintained.

[소파블록의 거치방법][How to mount sofa block]

Hereinafter, a method of mounting the sofa block having the above-described interlocking structure will be described.

5 is a view showing a state in which the sofa block of FIG. 1 is in a difficult state, FIG. 6 is a view showing an embodiment in which the sofa block of FIG. 1 is static, and FIG. 7 is another implementation of the sofa block of FIG. 1 A view showing an example, and FIG. 8 is a view showing another embodiment in which the sofa block of FIG. 1 is static.

As shown in FIG. 5, since the sofa block of the present invention has a geometrical relationship with the standard described above, even if it is difficult, it is difficult to interpolate not only between each part of the neighboring sofa block, but also between each part and the eastern part of the neighboring sofa block. It should be noted that locking can be done very robustly.

Next, the mounting method shown in FIG. 6 will be described. First, a sandstone mound (i) having a sea floor (x), a slope (y), and a top surface (z) is constructed. Next, the intermediate coating material (j) is coated and mounted on the mound (i). The slope of the slope formed by the intermediate cladding (j) mounted on the slope may be about 33.69 degrees as in the standard specification.

Next, the sofa block is laid and mounted on the sea floor (x) adjacent to the slope (y). At this time, one first leg portion 21 placed on the floor may be mounted as shown so that the two second leg portions 22 placed on the floor face the slope.

Next, a sofa block is erected and mounted on the first stage of the slope (y) adjacent to the sea floor (x). The sofa block mounted on the first stage is mounted so that the two second leg portions 22 placed on the floor face the sea floor, and the one second leg portion 22 placed on the floor faces the top end surface, and the slope ( Of the first leg portions 21 of the first stage of the sofa block in y), one first leg facing the sea floor is two first leg portions facing upward among the first leg portions 21 of the sofa block mounted on the sea floor It is placed between and is interlocked. Then, interlocking is also performed between the two second leg portions 22 of the slope placed on the floor and the one first leg portion 21 of the sea floor placed on the floor.

Next, a sofa block is erected and mounted at n stages of the slope (2 ≤ n, according to the drawing, n = 2, 3, 4). It is mounted so as to be oriented in the same direction as the sofa block mounted on the first stage. That is, the two second leg portions 22 placed on the slope floor face the sea floor, and the one second leg portion 22 placed on the slope bottom face the top surface, but the second leg portion of the n-stage sofa block (22) It is mounted so that one second leg of the second leg 22 of the sofa block of n-1 is placed between the two second leg portions facing the sea floor. As a result, one first leg of the n-stage first leg portion 21 facing the sea floor is between the two first leg portions of the n-1’s first leg 21 of the sofa block facing the top surface. Will be placed.

Next, the sofa block is laid and mounted on the slope (y) and the top (z), but the two second leg portions 22 placed on the slope are placed at the immediately preceding end (n=4). It is placed so as to surround one second leg portion 22, and mounts so that one first leg portion 21 is placed on the top surface. In this way, one second leg portion 22 positioned on the slope side but disposed upward is disposed between the two first leg portions 21 of the sofa block placed at the immediately preceding end and interlocked.

Next, a sofa block is erected and mounted on the top surface z, with the two second leg portions 22 placed on the floor facing the slope, and one second leg portion 22 placed on the floor facing the top end. Orient the sofa block so that it is. At this time, the two second leg portions 22 facing the slope are laid across the slope and the top end surface, and are interlocked by mounting the sofa block to surround one first leg portion 21 placed on the top surface. Let this happen.

The above-described mounting method of the sofa block is a description of the portion shown in the drawing of FIG. 6. However, the sofa block must also be mounted on the side of the part shown on the drawing (ie, the direction through which the drawing paper penetrates or exits). According to an embodiment of the present invention, interlocking between the sofa blocks arranged in the side can be performed by alternately mounting sofa blocks in a direction complementary to the mounting direction of the sofa block from the same end to the side as described above. .

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

Next, lay the sofa block on the sea floor (x) and the slope (y) and mount it. At this time, the two second leg portions 22 are placed on the floor toward the sea floor, and one first leg portion 21 is mounted on the floor toward the slope.

Next, the sofa block is laid down on the n-stage of the slope and mounted, and the two second leg portions 22 are placed on the floor toward the sea floor and one first leg portion 21 is placed on the floor toward the top surface. . At this time, the two second leg portions 22 placed on the floor from the n-stage sofa block facing the sea floor are one first leg portion 21 placed on the floor from the n-1 stage sofa block toward the ceiling surface. Mount to wrap. Then, one second leg 22 protruding upward from the n-stage sofa block toward the sea floor is between the two first leg portions 21 protruding upward from the n-1 sofa block toward the ceiling. It is inserted and interlocked.

Next, the sofa block is mounted on the top surface (z), but the two second leg portions 22 placed on the floor face the slope and one second leg portion 22 placed on the floor faces the top end. It is mounted, and the two second leg portions facing the slope are mounted so as to surround one first leg portion placed on the top end surface of the sofa block mounted between the slope and the top end surface.

The above-described mounting method of the sofa block is a description of the portion shown in the drawing of FIG. 7. However, the sofa block must also be mounted on the side of the part shown on the drawing (ie, the direction through which the drawing paper penetrates or exits). According to an embodiment of the present invention, interlocking between the sofa blocks arranged in the side can be performed by alternately mounting sofa blocks in a direction complementary to the mounting direction of the sofa block from the same end to the side as described above. .

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

Next, the sofa block is laid down on the first stage of the slope and mounted, with the two first leg portions 21 placed on the floor facing one side and one second leg portion 22 placed on the floor facing the other side. do. In this way, the sofa block is laid on the n-stage (however, 2 ≤ n) of the slope, and the sofa blocks are alternately mounted on the n-1 stage in a complementary direction.

When mounting on the slope (y) is completed, a sofa block is erected and mounted on the top surface (z).

When mounting the sofa block on the ceiling, it can be mounted in an upright position. At this time, two of the second leg portions placed on the bottom of the ceiling surface are arranged to be one of the second leg portions placed on the floor in the sofa block placed on the immediately preceding slope, and one of the second leg portions placed on the bottom of the top surface. The second leg of the dog is mounted so that the two leg portions are disposed on the floor in the sofa block placed on the immediately front slope, so that interlocking can be implemented while the sofa blocks are disposed so as to be more dense with each other.

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 slope direction of the slope or laying it in the direction of the contour line, and at the bottom of the sea, the slope and the top, and the boundary thereof Not only can the sofa block erect or lay down and mount differently, but also the sofa block erect or lay down and mount differently within the same floor, appropriately respond to the wave propensity at the location where the breakwater is installed. The sofa block can be mounted.

Meanwhile, according to the present invention, the weight and height (H; see FIG. 3) of one sofa block laid down can be designed to be equal to the weight of the two tetrapods of the designed standard and the height of two floors. According to this, by mounting one sofa block, it is possible to achieve the same effect as two-layered two tetrapods, so that the construction process can be very simple. In addition, when repairing and/or reinforcing a breakwater previously constructed with tetrapods, determine the weight and height (H) of one sofa block lying down, and the weight and height of two floors of the pre-designed standard. By designing equally, the standard is compatible with each other to enable repair/reinforcement construction, and it is possible to simplify construction by having the effect of mounting two tetrapods when mounting one sofa block.

[소파블록 제작용 거푸집][Formwork for fabricating sofa block]

Hereinafter, a form for manufacturing the above-described sofa block will be described.

9 to 19, as an embodiment of the present invention, a formwork for fabricating a sofa block is an eastern formwork 710 that mainly covers the eastern part of the sofa block, and each

part formwork

Looking at one shape of the eastern formwork 710 divided into three with reference to FIGS. 10 and 11, the eastern formwork 710 extends along the longitudinal direction of the eastern part 10 of the sofa block, but is 1 in the radial direction of the eastern part. The eastern portion 711 covering a portion corresponding to /3, a first leg portion 712 covering a portion corresponding to 1/2 in the radial direction, and two second leg portions ( The second leg portions 713 that cover 22) by 1/4 in the radial direction are connected to each other.

9, 28, and 29, the pedestal 79 is a structure that is installed on the ground and supports the formwork 70 that is mounted in a form having a height longer than that of a width, that is, an erect form. The pedestal 79 has six radial members 794 extending radially with respect to the center 791. Since the interval between the radial members 794 is 60 degrees, they are arranged at equal intervals. The radial member 794 may be in the shape of a square tube or an I-beam, H-beam, or C-beam shape.

The radial edges of the six radial members 794 are connected to each other by a circular ring-shaped outer ring member 793. The outer ring member 793 may be in the shape of a square tube or in the form of I-beam, H-beam, or C-beam. Stopper members 7933 are installed at three of the six points of the outer ring member 793 meeting the radial member 794 at intervals of 120 degrees. When the second end surface formwork 732 of the formwork 70 mounted on the base 79 is opened, the stopper member 7933 has an inclined surface facing the outer surface of the second end surface formwork 732 of the base. . The inclined surface of the stopper member 7933 limits the angle of opening when the second end surface formwork 732 is opened, thereby preventing an operator from injuries or damage to the formwork. The stopper member 7933 may be detachably installed on the pedestal 79.

Support surface members 7922 are installed at three of the six points of the inner ring member 792 meeting the radial member 794 at intervals of 120 degrees. Of the six radial members 794, the stopper members 7933 are installed together on three radial members 794 on which the support surface members 7922 are installed. The support surface member 7922 faces and abuts the bottom surfaces of the three support portions 78 of the second leg part formwork 722.

The outer ring member 793 has a circular ring shape so that all portions of the outer ring member 793 are disposed away from the center 791 at the same distance, thereby ensuring the stability of the formwork 70 mounted on the pedestal 79. . The radius of the outer ring member is set to be slightly larger than the lower end of the three corners of the second leg form 722 of the formwork 70. On the other hand, the inner ring member 794 has a regular hexagonal ring shape and connects neighboring radial members 794 in a straight line. And the support part 78 is disposed more radially outward than the eastern part. Therefore, the radial inner ring member 794 greatly improves the resistance of the pedestal 79 against the load applied through the second leg portion of the formwork 70, and more stably while distributing the weight of the heavy formwork on which concrete is placed. Support.

A center support member 7911 is installed at the center 791.

ii) one eastern formwork and three first end face formwork modules, and

iii) One form of the first leg

It can be handled as a total of 5 parts including. No matter how much the number of the formwork 70 is reduced, it is possible to manufacture a sofa block such as connecting two tetrapods while only one part is more than a tetrapod handled as four parts.

When the second end surface formwork 732 rotatably installed at the front end of the three corners of the second leg formwork 722 is opened without any restrictions, there is a risk of injury to the operator. Accordingly, as shown in FIG. 22, a stopper member 7933 limiting the rotational opening range of the second end surface formwork 732 is installed on the pedestal 79 supporting the second leg part formwork 722. .

In addition, when storing or transporting the second leg formwork 722 and the second end surface formwork 732, the second leg formwork 722 and the second end surface formwork 732 are connected to each other through the

flanges

7223 and 7322. It can be stored or transported in a fastened state.

20 and 21, when the first end surface formwork 731 that is rotatably installed on the front end of the first leg portion 712 of the eastern formwork 710 is opened without any restrictions, there is a risk of injury to the operator. There is. Accordingly, the first leg portion 712 of the eastern formwork 710 and the first end surface formwork 731 may be connected to each other by a tension member 89 such as a wire or a chain.

The rib 717 of the first leg portion 712 of the eastern formwork 710 is provided with a connection hole 7125 to which one end of the tension member 89 is connected and fixed. In addition, a connection hole 7315 to which the other end of the tension member 89 is connected and fixed is provided in the rib 717 of the first end surface formwork 731.

The length (L) of the tension member 89 is the distance between the connection hole 7125 and the connection hole 7315 when the first end surface formwork 731 is closed with respect to the eastern formwork 710 Longer than (D _C ). In addition, the length (L) of the tension member 89, the first end surface formwork 731 is opened with respect to the eastern formwork 710 and rotates to form a straight line including the hinge shaft member 7319 As a reference, when the connection hole 7315 and the connection hole 7125 are positioned opposite to each other, the distance D _L between the two

connection holes

7315 and 7125 is shorter.

D _C <L <D _L

Then, the opening angle of the first end surface formwork 731 may be limited.

In addition, the length of the tension member 89 is set to a length that is more open than the vertical surface including the hinge shaft member 7319 and less open than the horizontal surface including the hinge shaft member 7319 I can.

The degree of opening of the first end surface formwork 731 is preferably closer to a vertical surface than to the horizontal surface. The length of the tension member 89 may be appropriately selected to meet these conditions.

As described above, the partial formwork is in contact with each other by the flange portion. 23 to 25, flange grooves 81 are formed in both flanges in contact with each other. Flange grooves 81 respectively formed in the two flanges in contact with each other are provided at positions corresponding to each other. In addition, 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 interposed therebetween. The bolt support member 82 may be installed for each flange groove 81.

Between the pair of bolt support members 82, the ring portion 841 of the bolt 84 in the form of an eye bolt is accommodated. In the state in which the ring portion 841 is accommodated, a bolt support shaft 83 is provided through the pair of bolt support members 82. The bolt support shaft 83 passes through the ring portion 841. Accordingly, the threaded portion 842 of the bolt 84 may rotate around the bolt support shaft 83.

A nut 85 is screwed to the threaded portion 842. In a state where the nut 85 is disposed close to the edge of the bolt 84, when the bolt 84 is rotated, the threaded portion 842 of the bolt 84 becomes a flange groove 81 of two flanges in contact with each other. Can be inserted into or deviated from it. When the nut 85 is tightened while the threaded portion 842 is fitted into the flange groove 81 of the two flanges in contact with each other, the two flanges in contact with each other can be strongly compressed. This fastening structure makes it very convenient to assemble and remove the formwork.

A fastening hole 86 may be further formed between the plurality of flange grooves 81 in the flange. The fastening holes 86 are provided in both flanges in contact with each other. The fastening holes 86 of the two flanges in contact with each other are provided at positions corresponding to each other. When it is difficult to secure the fastening force between the partial formwork only with the bolts 84 (for example, if the size of the formwork is large), additional bolt-nuts (not shown) are additionally fastened to the fastening hole 86 to supplement the fastening force. I can.

In the state in which the formwork is installed, the bolt support member 82 and the bolt 84 may be provided at a position capable of rotating in the direction in which the bolt 84 is separated from the flange groove 81 by its own weight among the two flanges. have. Accordingly, the first flange 7311 of the second leg form 722, the second flange 7102 and the third flange 7103 of the first leg portion 712 of the eastern formwork 710, and the first leg form 721 ), the bolt support member 82 and the bolt 84 may be provided on the third flange 7213.

On the other hand, the first end surface formwork 731 and the second end surface formwork 732 are parts that move greatly when assembling and removing the formwork. Therefore, if the bolts 84 are installed on the first end surface formwork 731 and the second end surface formwork 732, there is a risk of damage to the bolt or injury to the operator due to the bolt. Accordingly, the bolt support member 82 and the bolt 84 may be provided on the third flange 7103 of the second leg portion 713 of the eastern formwork 710.

On the other hand, in the case where both flanges in contact with each other in the state in which the formwork is installed are in a position where the bolt does not rotate due to gravity, the bolt support member 82 and the bolt 84 may be provided on either side of the two flanges. For example, the first flange 7101 of the eastern part 711 of the eastern formwork 710 corresponds to this. In addition, even when both flanges rotate in the same direction by gravity in the state in which the formwork is installed, the bolt support member 82 and the bolt 84 may be provided on either side of the two flanges. For example, the first flange 7101 of the second leg portion 713 of the eastern formwork 710 corresponds to this. Therefore, the first flange 7101 of the eastern part 711 of the eastern formwork 710 and the first flange 7101 of the second leg part 713 of the eastern formwork 710 are left and right of the eastern formwork 710 It should be installed on either side. Then, in fastening the same three eastern formwork with each other, all can be treated the same. That is, the installation position and order of the three eastern formwork can be arbitrarily made.

Referring to FIGS. 26 and 27, the structure of the window 75 includes an opening/closing structure for opening and closing the hinge door 751 installed on the outer surface of the formwork, and a locking structure for firmly supporting the closed hinge door 751. The hinge door 751 may be opened more outwardly than the outer surface of the formwork around the hinge axis of one side. A locking structure is provided at an end of the hinge door 751 opposite to an end provided with a hinge shaft.

The locking structure includes a first support portion 752 provided on the hinged door side and a second support portion 753 provided on the outer surface of the formwork. A hook handle 754 is rotatably installed on the first support portion 752. The hook handle 754 includes a handle 7451 that can be gripped by an operator, and a cantilever hook 7452 that is caught and fixed by the second support portion 753. The cantilever hook 7452 has a cantilever structure extending in an arc direction around the rotation axis of the hook handle 754. The distal end of the cantilever hook 7452 is easily deformed when it is caught by the second support 753, but the amount of deformation decreases toward the base end of the cantilever hook 7452. Therefore, the deeper the cantilever hook 7452 is inserted into the second support portion 753, the closer the hinge door is to the outer surface of the formwork. When the hinge door of the window structure is opened, the inner space of the formwork can be seen.

[거푸집의 조립][Assembly of the formwork]

The assembly of the formwork can be made in the following 1 to 7 steps.

1) Arrange the pedestal 79 at an appropriate location on the ground (see Fig. 28).

2) A central support member 7911 is installed at the center 791 of the pedestal 79, and a stopper member 7933 is installed at a predetermined position among the connecting portions between the outer ring member 793 and the radial member 794. (See Figure 29).

3) On the pedestal 79, a module of the second leg form 722 and the second end surface form 732 is installed. The installation process of the module may be performed in a state in which the second end surface formwork 732 is closed to the second leg part formwork 722. By lifting the module, while matching the center of the center support surface member 7912 at the center of the upper end of the center support member 7911 and the bottom surface of the second leg mold 722, from the second leg mold 722 The three support portions 78 extending downward are matched to a predetermined position among the connecting portions between the inner ring member 792 and the radial member 794, and the second leg-shaped mold is fixed on the pedestal (see FIG. 30).

4) Three modules of the eastern formwork 710 and the first end surface formwork 731 are sequentially installed on the second corner formwork 722. The installation process of the module may be performed in a state in which the first end surface formwork 731 is closed to the eastern formwork 710. In contrast, the installation process of the module may be performed even when the first end surface formwork 731 is open with respect to the eastern formwork 710 (this means that the opening angle of the first end surface formwork 731 is the tension member 89). It is possible by being limited by). When assembling the eastern formwork 710 while the second end-side formwork 732 is closed to the second leg-side formwork 722, the second end-side formwork 732 is closed to the second leg-side formwork 722 By guiding the fastening of the eastern formwork 710, assembly is easier (see FIG. 31).

5) The first end surface formwork 731 is made open to the eastern formwork 710. If the first end surface formwork 731 is assembled in an open state in step 4) above, step 5) may be omitted.

6) The first leg form 721 is installed on the eastern formwork 710 (see Fig. 31).

7) Close the first end face formwork 731.

When the sofa block formwork according to the above embodiment is installed in an erect state, a concrete pouring hole 77 is provided in the first end surface formwork 731 disposed on the upper part, and the upper surface of the first leg part formwork 721 A window 75 is provided in the window 75, and a window 75 is also provided near the upper end of the second leg portion 713 of the eastern formwork 710. Since the three eastern molds have the same installation location of the window, there is no direction between the three eastern molds, so the assembly process is simpler.

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

[소파블록의 제조 방법][Method of manufacturing sofa block]

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

The general procedure of assembling the formwork, pouring and compacting it, curing it, demolding and cleaning the formwork, and displacing and installing the cured sofa block is not significantly different from that of the existing sofa block. The description thereof will not be described in detail, and a description will be made of a part related to the technical idea of the present invention.

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

For concrete pouring, a hopper, chute, and pump car can be used. It is important to note that the drop from the discharge port of the chute pump piping to the pouring surface should be less than 1.5m so that no material separation occurs.

In addition, the concrete of the second leg is compacted together with the first pouring step or after the first pouring step through the window of the second leg disposed at the bottom (first compaction step).

The compaction during pouring is carried out to spread the ready-mixed concrete to the corners of the formwork to dissipate unnecessary air contained in the ready-mixed concrete and to make dense concrete. If compaction is insufficient, deep air bubbles are generated and the strength decreases. On the contrary, if the compaction is excessive, it may cause the material to separate and affect the 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 compaction, air bubbles in the concrete gather near the shaft of the vibrator, so it is recommended to gradually remove the shaft placed at the tip of each part of the sofa block from the concrete. Particularly, since the tip of each part is a part where it is easy to appear, it is good to perform a vibrator so that the concrete spreads sufficiently in this part.The window is formed in the formwork of the present invention, so that visibility and accessibility are secured to facilitate the compaction process of the tip of each part. It can be done.

Next, while the window of the second leg disposed at the lower part is covered, concrete is poured through the concrete pouring hole, and the concrete is poured to a position lower than the height of the window provided in the first leg disposed at the upper part. Confirm and pour concrete (2nd pouring step).

Then, the concrete of the first leg is crushed through the window of the leg disposed at the top together with or after the second pouring step (second compaction step).

Before and after the compaction step, a spacing step in which a thin and long stick-shaped spacing stick is inserted between the formwork and the concrete may be further performed.

Next, while the window of the first leg is covered, concrete is poured through the concrete pouring hole 77, but the concrete is poured while confirming that the poured concrete is filled to the ceiling (third pouring step). .

When the pouring is finished like this, select the temple. Choosing the ceiling is performed for feminine concrete after the concrete is sufficiently stabilized after pouring. By pressing the female part in the selection of the temple, it removes water and air that tend to accumulate in the taper of the temple.

After that, cure.

Then, the formwork is demolded, which is achieved after the compressive strength of the concrete is expressed above a predetermined level. The demolding can be done roughly in the reverse order of assembly as follows.

1) Open the first end surface formwork 731 and the second end surface formwork 732 (see Fig. 32).

2) The first leg form 721 on the eastern formwork 710 is demolded (see Fig. 33).

3) The modules of the eastern formwork 710 and the first end surface formwork 731 on the second leg formwork 722 are demolded.

4) When the sofa block is completely cured, lift the sofa block out.

5) Clean the formwork.

According to the above-described formwork of the present invention, it is possible to secure visibility and compaction of each part disposed at the lower part when curing concrete, so that concrete pouring and compaction can be faithfully performed even for weak parts, thereby securing the strength of the sofa block. .

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

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 transformation can be made. In addition, even if not explicitly described and described the effects of the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effects of the configuration should also be recognized.
