Here, in the multi-porous concrete block, multi-gol means to have a plurality of protrusions in the skeleton of the rectangular parallelepiped, and the term "pore" means that a plurality of through-holes are formed through the rectangular parallelepiped.

As shown in Figures 8 and 9, the concrete block 500 produced by the formwork of the present invention is used as artificial reefs, the size and weight is quite large. The concrete block 500 may be formed at four corners of the left side 503, the right side 504, the front side 505, and the rear side 506 of the rectangular parallelepiped except for the upper and lower surfaces 501 and 502 of the rectangular parallelepiped. Protruding portions 511, 512, 513, and 514 are formed, respectively, and through-holes 521, 522, and 523 are formed on each side of the rectangular parallelepiped, which penetrates the center in three directions of up, down, left, and front directions. . The concrete block 500 may be manufactured in a cube shape in order to facilitate manufacturing, in which case the plurality of assembly frames 300 constituting the formwork of the present invention will all have the same molding frame 302. . Reinforcement is entered into the concrete block 500 is shown in Figure 9, the arrangement of the reinforcement is made after placing and assembling the formwork of the present invention, and then the concrete material is put into the formwork of the present invention.

FIG. 8 shows the bottom surface 502 to face the front side and the back surface 506 to the bottom side because the concrete block 500 shows the state in which the concrete block 500 is placed when being introduced into the sea as artificial reefs. However, in the arrangement | positioning of the formwork of this invention, it will be in the state named differently from FIG. In the present specification, the direction is indicated based on the arrangement of the formwork.

1 to 5, the formwork 10 of the present invention includes a bottom plate 100. In the central portion of the bottom plate 100 is disposed a vertical pipe 200 is formed with a through hole in the vertical direction. In addition, four assembly frames 300 are disposed at the corners of the bottom plate 100. The assembly frames 300 contact the bottom plate 100 and the vertical pipes 200 and combine with each other to form a space in the shape of the porous porous block 500. The block 500 is manufactured by arranging the reinforcing bar as shown in FIG. 9 and filling and hardening concrete in such a space. The number and shape of the assembly frame can be changed according to the shape of the concrete block to be manufactured. For example, the concrete block to be manufactured has a regular hexagon on the top and bottom and a square on the side thereof. As long as the ball is formed, six assembly frames having the same shape mold may be used.

Specifically, the assembly frame 300 is to dismantle the molding frame 302 for the shape of the concrete block 500, the assembly frame coupling means 340 for coupling the two neighboring assembly frame and the assembly frame 300. In order to reverse the assembly frame 300 includes at least one assembly frame reversing means 350.

The mold 302 has a flat portion 310 which is flat in the vertical direction. This planar portion 310 is for forming the shape of the side of the concrete block 500 shown in FIG. Four protrusions 320 protruding backward are formed at four corners of the planar portion 310. These protrusions 320 are for forming the shape of the protrusions 511, 512, 513 and 514 of the concrete block 500 shown in FIG. In addition, the mold 302 includes a horizontal pipe 330 extending in the horizontal direction from the center of the plane portion 310, the through-hole is formed in the horizontal direction therein. The horizontal pipe 330 is in close contact with the vertical pipe 200, and the shape of the distal end thereof corresponds to the curvature of the vertical pipe 200. Thus, the horizontal pipe 330 works with the vertical pipe 200 to form the through holes 522 and 523 passing through the center in the left and right directions and the front and rear directions of the concrete block 500 shown in FIG. 8. The horizontal pipe 330 may be used in a solid form, but since the material is made of a metal material, in particular, a steel material, a hollow pipe form is preferable. However, the present invention does not exclude the use of a solid form. On the other hand, the end of the horizontal pipe 330 on the opposite side of the plane portion 310 may have a closed or open shape. Even if the end of the horizontal pipe 330 is open, if the edge of the end of the horizontal pipe 330 is in close contact with the vertical pipe 200, the through holes 522 and 523 penetrating the center in the left and right and front and rear directions of the concrete block 500 It is preferable to use the open form because there is no obstacle to formation. In this specification, therefore, horizontal pipes, which are the most economical shape, are used as reference terms to form the through holes 522 and 523 of the concrete block 500. However, it is as mentioned above that the hollow form and the closed end may be used alternatively.

Assembly frame reversing means 350 includes a jack bolt 352, one end of which passes through the planar portion 310 of the forming die 302, and the other end is formed with a handle for rotation. The jack bolt 352 is a flat portion at the time of forming the formwork 10 of the present invention by the arrangement and assembly of the assembly frame 300, that is, before the concrete material is introduced into the space formed in the formwork 10. It does not penetrate the inner wall of the 310 but is arranged to coincide with the inner wall of the planar portion 310. However, after the material is put into the space of the formwork 10 and the concrete is cured, the material is advanced through the inner wall of the flat part 310 as described below. As described above, in order to operate the jack bolt 352, the jack bolt is screwed with the nut 354, and the nut 354 is coupled to and supported by the nut support frame 356.

The nut support frame 356 for fixing the nut 354 is an upper nut support frame 356-1 and a lower nut support frame 356-2 that are coupled to the nut 354 at the upper and lower portions of the nut 354, respectively. It can be configured as. These upper and lower nut support frames 356-1 and 356-2 are coupled to the outside of the mold 302. At this time, the upper and lower nut support frame (356-1 and 356-2) is preferably coupled to the outside of the two projections 320 horizontal in the mold 302. In addition, a mold support frame 360 for supporting it is formed on the outside of the mold 302, and the upper and lower nut support frames 356-1 and 356-2 are preferably molded mold supports. It is also combined with the frame 360.

As shown in the drawing, the assembly frame reversing means 350 is preferably an upper assembly frame reversing means 350-1 and a lower assembly frame reversing means 350-2 installed above and below the horizontal pipe 330. Is done. And, in the assembly frame 300 in the position corresponding to the position where the upper assembly frame reversing means 350-1 is formed scaffolding 370 allowing a person's access to operate the upper assembly frame reversing means (350-1) Is formed. The position corresponding to the position where the upper assembly frame reversing means 350-1 is formed refers to a suitable position where a person can operate the upper assembly frame reversing means 350-1 by raising the footrest 370, and the key of the person In consideration of this, the footrest 370 is placed at a position lower than the position of the upper assembly frame reversing means 350-1.

The scaffold 370 is supported by the bracket 372 which is coupled to the mold support frame 360 to be coupled to the mold 302 itself or the mold 302. The bracket 372 is also bent vertically upward at the end of the footrest 370 and also supports a safety railing 374 for safety. Thus, the operator climbs up the scaffold 370 through the ladder 390 installed in the mold 302 to operate the jack bolt 352.

The operation of the assembly frame reversing means 350 for dismantling the formwork 10 of the present invention will now be described with reference to FIG. 7. In order to dismantle the formwork 10 after the concrete block 500 is hardened by the formwork 10, the worker rotates the handle 352 ′ of the jackbolt 352 in the direction in which the jackbolt 352 moves forward. . At this time, it is preferable to simultaneously rotate the jack bolts 352 in the upper assembly frame rewinding means 350-1 and the lower assembly frame rewinding means 350-2. Then the jack bolt 352 is going to move forward but can not move forward because it is blocked by the generated concrete block (500). The force of the jack bolt 352 to be advanced causes a reaction to the mold 302 and the nut support frame 356 of the assembly frame 300 corresponding to the assembly frame 300 is reversed. As the jack bolt 352 is rotated, the assembly frame 300 moves backward, whereby a space is formed between the mold frame 302 and the concrete block 500. This process is carried out for all four assembly frames 300 and then the vertical pipe 200 is removed from the concrete block 500 formed by lifting by a lifter such as a crane using a turnbuckle 210 installed therein. The inner concrete block 500 is fully exposed. The exposed concrete block 500 is lifted by a lifter such as a crane, transferred to a ship or barge, and then moved to a desired sea and dropped.

On the other hand, in order to couple the neighboring assembly frame 300 in the formwork 10 of the present invention, the assembly frame coupling means 340 is provided.

First, at both sides of the planar portion 310 of the forming die 302, extended portions 380 are formed which are bent backwards, and the extension portion 380 has a plurality of through holes 382 in the vertical length direction. Is formed (see FIG. 3).

Assembly frame coupling means 340 is bent at a right angle with a predetermined length in the vertical direction to be coupled to the extensions 380 formed in the two assembly frames 300 adjacent to each other, the two surfaces are bent It includes a bending piece 342 is formed with a plurality of through holes 344 in the vertical longitudinal direction. That is, the bending piece 342 has a predetermined length in the vertical direction, and two surfaces that meet at right angles are integrally formed, and the plurality of through holes 344 are formed in the two surfaces in the longitudinal direction.

One side of this bending piece 342 is in contact with the extension portion 380 of one of the neighboring assembly frame 300 and their through holes 344 and 382 to coincide with each other, the first bolt (not shown) C) penetrates through the through holes 344 and 382 and engages with a first nut (not shown). In a similar manner, the other side of the bending piece 342 abuts so that the extension 380 of the other assembly frame of the neighboring assembly frames 300 and their through holes 344 and 382 coincide with each other, and the second bolt (Not shown) passes through the through holes 344 and 382 and engages with a second nut (not shown). Thus, in the formwork of the present invention, four assembly frames 300 are combined with neighboring assembly frames.

At this time, preferably, as shown in Figure 2, at least two horizontal forming frame support frame 362 in the form of a horizontal bar for supporting it is formed on the outside of the forming frame 302, the horizontal forming frame support frame 362 supports the planar portion 310 of the mold 302 and also supports the extension 380 of the mold 302 at its distal end.

In the present invention, the molding die 302 of the assembly die 300 is formed of a metal material, in particular a steel material.

As described above, the formwork 10 of the present invention can be formed by simply and quickly combining the bottom plate 100, the vertical pipe 200, and the four assembly molds 300, and also manufactured a concrete block. Its decommissioning work can then be carried out simply and quickly, improving productivity for concrete blocks such as artificial reefs. In addition, since the parts of the formwork of the present invention is made of a metal material, in particular, steel material, it is possible to repeatedly reuse and efficient.
