Description

Technical Field

[0001] The utility model belongs to the technical field of wall support, in particular to a prefabricated formwork wall support device. Background Art

[0002] Prefabricated formwork wall support components are mainly used in the process of formwork wall installation and concrete pouring. Prefabricated formwork wall support components are mainly steel pipe supports. During installation, one end of the steel pipe is connected to the wall of the formwork wall, and the other end of the steel pipe is connected to the ground anchor. Due to the non-uniform size and height of the prefabricated formwork wall components, the fixing points of the steel pipe support and the ground anchor connection, and the fixing points of the prefabricated formwork wall support component and the steel pipe support connection have been fixed, resulting in the difficulty in determining the size of the connecting steel pipe at one end of the embedded ground anchor and one end of the formwork wall support component. When the steel pipe support is connected, the positioning of the prefabricated formwork wall support is inaccurate, the support is unstable, and the installation accuracy is insufficient. It is difficult to meet the requirements of the prefabricated formwork wall construction specifications. Since the fixing points at both ends are fixed and cannot be adjusted, it is necessary to determine the size of the connecting steel pipe according to the distance between the two ends on site, and then process the steel pipe. This support method has a lot of labor costs, material costs and time costs.

[0003] For example, a Chinese utility model patent with an authorization announcement date of 2023.01.24 and an authorization announcement number of CN218375183U discloses a diagonal brace structure for a swimming pool casting formwork, including a single formwork: the number of the single formworks is two, and the two single formworks are respectively located on both sides of the casting wall, and a plurality of back ribs are installed on the side of the single formwork away from the casting wall, and a plurality of tension bolts are penetrated between the two single formworks, and the tension bolts are pressed on the surface of the back ribs, and a triangular base is provided at the bottom of the right side of the right single formwork, and two diagonal brace assemblies are provided in the inner cavity of the triangular base.

[0004] In the above prior art, the length of the diagonal brace is adjusted by rotating the handle to support the wall, but there are the following disadvantages:

[0005] 1. The diagonal brace is pinned on the surface of the single template. When the user turns the handle to exert force, the pin is easily pulled out with the force of rotation;

[0006] 2. The pins are inserted into the surface of the single template. If you want to firmly insert the pins, you need to use tools to drive the pins into the single template. Therefore, installation and disassembly are more troublesome, and as the number of disassembly increases, the surface of the single template will also be damaged.

[0007] Therefore, how to effectively enhance the stability of the connection between the diagonal brace and the formwork and facilitate installation and disassembly for multiple turnover uses is a technical problem that needs to be solved urgently. Utility Model Content
