[0012] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 The present invention will be described in further detail below.

[0013] Reference Figures 1-9 This invention discloses a cement molding construction method, comprising the following steps: S1. Based on the existing cement model, find the corresponding airbag 1 manufacturer. The airbag 1 manufacturer will produce airbags 1 with the corresponding shape according to the model. The cement model is designed by a design institute and manufactured using 3D printing equipment.

[0014] The bottom end of the airbag 1 is integrally formed with a rubber plate 11, and the rubber plate 11 has mounting holes 111. The rubber plate 11 is located on the side of the bottom end of the airbag 1. A fixing component 4 is provided on the ground to fix the rubber plate 11 to the ground.

[0015] S2. When installing the airbag 1, first place the rubber plate 11 in the corresponding fixing component 4 position, and fix the rubber plate 11 through the fixing component 4. After the airbag 1 is installed and fixed, inflate the airbag 1 so that the air pressure of the airbag 1 reaches the construction strength.

[0016] The fixing component 4 includes a base plate 41 and a pre-embedded connecting plate 411 embedded in the ground concrete. The pre-embedded connecting plate 411 is fixed below the base plate 41, and the upper surface of the base plate 41 is flush with the ground. An inverted U-shaped connecting frame 413 is fixed at the upper center of the base plate 41. Multiple positioning rods 412 are fixed on the base plate 41. The rubber plate 11 has positioning holes 112 for the positioning rods 412 to be inserted. When fixing the rubber plate 11, the mounting holes 111 are aligned with the connecting frame 413, so that the connecting frame 413 passes through the mounting holes 111, and the positioning rods 412 are inserted into the corresponding positioning holes 112.

[0017] The fixing assembly 4 also includes a clamping housing 42, within which a first movable plate 431 and a second movable plate 441 are disposed, located on opposite sides of the connecting frame 413. A first locking block 43 is fixed to the side of the first movable plate 431 closest to the second movable plate 441, and a second locking block 44 is fixed to the side of the second movable plate 441 closest to the first movable plate 431. The bottom surface of the first locking block 43 and the top surface of the second locking block 44 are both inclined surfaces. Both the first locking block 43 and the second locking block 44 can be inserted into the connecting frame 413. When the first locking block 43 and the second locking block 44 are inserted into the connecting frame 413, the top surface of the first locking block 43 contacts the inner top surface of the connecting frame 413, and the bottom inclined surface of the first locking block 43 contacts the top inclined surface of the second locking block 44.

[0018] A first spring 432 is provided on the side of the first movable plate 431 away from the second movable plate 441. The first spring 432 is fixed between the inner wall of the clamping housing 42 and the first movable plate 431. Two first rods 433 are fixed on the side of the first movable plate 431 away from the first spring 432. The first rods 433 pass through the second movable plate 441, and the second movable plate 441 can slide along the first rods 433. A first connecting plate 434 is fixed to the end of the first rod 433 away from the first movable plate 431. A first pressing rod 435 is fixed on the first connecting plate 434 and extends out of the clamping housing 42.

[0019] A second rod 443 is fixed on the second movable plate 441. The second rod 443 passes through the first movable plate 431. The first movable plate 431 can slide along the second rod 443. A second spring 442 is fixed between the second movable plate 441 and the inner wall of the pressing housing 42. A second connecting plate 444 is fixed on the side of the second rod 443 away from the second movable plate 441. A second pressing rod 445 is fixed on the second connecting plate 444. The second pressing rod 445 extends out of the pressing housing 42.

[0020] When the rubber plate 11 is pressed and fixed, after placing the rubber plate 11 on the base plate 41 on the ground, press the first pressing rod 435 and the second pressing rod 445, causing the first moving plate 431 to compress the first spring 432 and the second moving plate 441 to compress the second spring 442, thereby separating the first locking block 43 and the second locking block 44. Then, align the middle position of the first locking block 43 and the second locking block 44 with the position of the connecting frame 413, release the first pressing rod 435 and the second pressing rod 445, and the first locking block 43 and the second locking block 44 are inserted into the connecting frame 413. At the same time, the pressing housing 42 presses the rubber plate 11.

[0021] When it is necessary to disassemble the rubber plate 11, the first pressing rod 435 and the second pressing rod 445 need to be pressed simultaneously. The first pressing rod 435 pushes the first moving plate 431 to squeeze the first spring 432, thereby causing the first locking block 43 to disengage from the connecting frame 413. The second pressing rod 445 pushes the second moving plate 441 to squeeze the second spring 442, thereby causing the second locking block 44 to disengage from the connecting frame 413. Then, the pressing housing 42 is removed from above the rubber plate 11, and the rubber plate 11 can be removed from the base plate 41.

[0022] S3. Steel structure profiles 2 are installed on both sides of the airbag 1 installation position.

[0023] The steel structure profile 2 includes multiple uprights 21 and multiple crossbars 22. The bottom of the uprights 21 is fixed to the ground, and the crossbars 22 are installed on the uprights 21 and fixed to the uprights 21 by steel pipe fasteners. The placement of the uprights 21 and crossbars 22 can be set according to the shape of the airbag 1. In this embodiment, the airbag 1 model is an elephant, with the hindquarters of the elephant on the ground and the head and trunk tilted towards the sky. The crossbars 22 are tilted, with the tilt angle of the crossbars 22 being approximately the same as that of the trunk. Multiple crossbars 22 can be set.

[0024] S4. Attach multiple steel mesh pads 3 to the outer wall of the airbag 1. The steel mesh pads 3 are evenly distributed along the outline of the airbag 1. After the steel mesh pads 3 are fixed to the airbag 1, tie the shaped steel mesh along the shaped airbag 1 and install the steel bars on the steel mesh pads 3.

[0025] The steel mesh pad 3 is made of rubber. The steel mesh pad 3 includes a base 31 and an installation block 32 integrally formed with the base 31. The four installation blocks 32 are arranged in a cross shape on the base 31. The installation blocks 32 have a snap-fit ​​groove 321 for snapping the steel bars 5.

[0026] S5. Connect the reinforcing mesh to the steel structure profile 2. Connecting bars are welded and fixed between the reinforcing bars 5 and the horizontal bars 22 or vertical bars 21, thus securing the reinforcing mesh and increasing its stability. Next, proceed with the cement surface work, selecting either shotcrete or manual application based on the size of the molded volume. For smaller volumes, manual application is used; for larger volumes, shotcrete is used. During cement surface work, a pre-drilled opening is required to allow the airbag 1 to be removed.

[0027] S6. After the concrete has initially set, allow airbag 1 to release air, causing the mounting block 32 to separate from the reinforcing bar 5, and then remove airbag 1.

[0028] The cement molding construction method of the present invention can solve the problem of high construction difficulty in complex shaping, and can improve work efficiency and reduce labor costs.

[0029] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
