Meanwhile, referring to FIG. 5, a second through hole 210 is formed in the second die body 200. The second through hole 210 is formed at a position in communication with the first through hole 100 when one side of the second form body 200 is in close contact with one side of the first form body 100.

1, 5 and 6, one side of the tube 300 is closely installed on the other side of the second formwork body 200. Therefore, referring to FIGS. 1 and 5, the fixing frame 240 protrudes to surround the circumferential surface of the tube 300 that is in close contact with the other side edge of the second formwork body 200. 5 and 6, the tube 300 is formed in a closed shape, and one side and the other side are formed in a shape corresponding to the unevenness formed on the other side of the first die 200. On the other hand, one side and the other side of the tube is formed to have a predetermined thickness that can maintain the shape corresponding to the irregularities formed on the other side of the first formwork 100 in the air or the like state.

5 and 6, the tube 300 is formed with a tube tube 310 extending. The tube tube 310 is internally formed with the tube 300, and an end thereof is inserted into the second through hole 210 and the first through hole 110 to protrude toward the other side of the first die body 200. . On the other hand, the male screw portion 312 is formed at the end of the tube tube 310.

3, 4, 5 and 6, the first embodiment has a fixing part 400 for fixing the tube tube 310 to the other side of the first die body 100. The fixing part 400 is composed of a cylindrical body 410 and the contact plate 440.

4 and 6, the cylindrical body 410 has a fixing groove (not shown) from one side end, communicates with the fixing groove (not shown), and guide groove 420 to the other end. It is an extended form. 5 and 6, the fixing groove (not shown) is formed so that the end of the tube tube 310 protruding to the other side of the first die body 100 is fitted, the fixing groove (not shown) The grant) is provided with a female screw portion (not shown) corresponding to the male screw portion 312 of the tube tube 310. The female screw portion (not shown) is a tube tube fastening portion to which the male screw portion 312 of the tube tube 310 is screwed. 5 and 6, the check groove 420 is mounted in the guide groove 420 so that the tube 300 into which air or the like is introduced maintains a constant pressure.

3, 4, 5, and 6, the plate-shaped contact plate 440 is extended to one side of the cylindrical body 410 to the outside, and the male screw portion 430 is formed at the other end of the cylindrical body 410. ) Is formed. Referring to FIGS. 2 and 6, the contact plate 440 is configured such that one end of the cylindrical body 410 is tightly fixed to the other side of the first die body 100. Therefore, a fastening hole 442 for screwing with the first formwork body 100 is formed in the contact plate 440.

3, 4, 5 and 6, Embodiment 1 has an injection portion. The injection part is made up of an injection tube 500 and a coupling part 700. The injection tube 500 is a cylindrical tube connected to the other end of the cylindrical body 410 and communicated with the guide groove 420. At one end of the injection tube 500, a circular locking plate 510 is formed to be in close contact with the other end of the cylindrical body.

On the other hand, referring to Figure 3, the first embodiment has a ring-type gasket 600. Referring to FIG. 6, the gasket 600 is inserted into one side of the locking plate 510 so that the adhesiveness between one side of the locking plate 510 and the other end of the cylindrical body 410 is improved. Ring-shaped gasket insertion groove (not shown) corresponding to the shape of the is formed.

4 and 6, the coupling part 700 is inserted into the injection tube to one side and is caught by the locking plate 510 of the injection tube 500 so that the through hole 720 is formed to protrude to the other side. In addition, the coupling portion 700 is formed with a female screw portion (not shown) corresponding to the male screw portion 430 of the cylindrical body 410 to be screwed with the other side of the cylindrical body 410. 3, 4, 5, and 6, the holding protrusion 730 is formed to protrude radially on the outer periphery of the coupling portion 700.

Hereinafter, the use state and operation of the above-described embodiment will be described.

Referring to Figure 5 for the concrete outer wall of the first embodiment, which is configured by combining the tube 300, the second formwork body 200 and the first formwork body 100 at a certain distance from the building outer wall 800 Install the formwork. In this case, water or air is introduced into the tube 300 through the injection pipe 500, and the introduced air is not discharged to the outside by the check valve 422, so that the tube 300 maintains a constant pressure. Therefore, the left side and the right side of the tube 300 are spaced by a predetermined distance to maintain a constant shape. By maintaining a constant pressure by the check valve 422 it is possible to cure the poured concrete without the inner surface of the tube does not stick to each other and facilitate the expansion of the tube 300 after curing.

Referring to FIG. 5, the concrete 900 is poured between the building exterior wall 800 and the concrete exterior wall formwork. At this time, since the tube 300 in contact with the concrete 900 forms an uneven shape having a shape of a sculpture, the outer surface of the cured concrete 900 is cured in a shape corresponding to the uneven shape of the tube 300. . Therefore, when the uneven shape of the tube 300 forms the shape of the natural sculpture, the outer surface of the cured concrete also forms the shape of the corresponding natural sculpture.

5 and 6, after the concrete 900 is cured, water or air may be injected through the injection pipe 500 to remove the formwork for the concrete outer wall. When water or air is injected through the injection pipe 500, the tube 300 is expanded, and as the repulsive force acts between the right side of the concrete 900 and the left side of the first formwork body 100, the formwork for the concrete outer wall is formed. It can be easily removed. In addition, even after the concrete 900 is cured, the concrete 900 is not cured solidified integrally with the tube 300, and thus, the tube 300 is easily separated from the right side of the concrete 900.

Example 2

Example 2 relates to a concrete outer wall forming method according to the present invention. 7 is a block diagram of a second embodiment.

Example 2 has a formwork installation step (S10). In the formwork installation step (S10) by connecting the formwork for concrete outer wall according to the first embodiment described above to be installed so as to be spaced apart from the building outer wall at a predetermined interval.

After the formwork installation step (S10) has a concrete pouring step (S20). In the concrete placing step (S20), the concrete is placed between the installed formwork and the building outer wall in the formwork installation step (S10).

After the concrete pouring step (S20) has a concrete curing step (S30). In the concrete curing step (S30) it is to cure the concrete poured in the concrete pouring step (S20).

After the concrete curing step (S30) has a form dismantling step (S40). In the form dismantling step (S40), by injecting air or water into the injection portion of the formwork for concrete outer wall installed in the form installation step (S10) to expand the tube to separate the second formwork body from the cured concrete to dismantle the formwork.

The present invention can recycle the styrofoam used to form the concrete outer wall having the same shape as the natural sculpture after curing the concrete, and can be easily separated from the formwork and the cured concrete outer wall by expansion of the tube after curing, curing Since there is no need for post-treatment, such as removing styrofoam, it is possible to shorten the air and reduce the waste of manpower. In addition, since the tube 300 is cured by maintaining a certain shape such as a natural sculpture at a certain pressure during the curing process of the concrete outer wall, the inner surface of the tube does not stick to facilitate the expansion of the tube when removing the formwork, thereby easily removing the formwork. There is an advantage to this.
