With the continuous improvement of aluminum alloy formwork, aluminum alloy formwork has demonstrated good economic and social value in construction, safety, quality control and other aspects.

[0003] Since the contact surface between the aluminum alloy formwork and the concrete is relatively smooth, it is easy to bond with the concrete, making it inconvenient to disassemble and even causing certain damage to the concrete surface, affecting construction efficiency and quality.

The spring is sleeved outside the sleeve, and the two ends of the spring are respectively abutted against the pressure plate and the bottom of the installation groove. The limiting component is fixedly installed on the end of the sleeve extending outside the inner template or the outer template. A limiting groove is provided on the pull rod. When the limiting component is matched with the limiting groove, the side of the pressure plate away from the sleeve is flush with the surface of the inner template or the outer template. Otherwise, the pressure plate slides out of the installation groove under the action of the elastic force of the spring.

The support plate is fixedly installed outside the sleeve. The support plate is provided with a threaded hole corresponding to the limiting hole. One end of the limiting rod is threadedly connected to the threaded hole, and the other end passes through the threaded hole and the limiting hole in turn and extends into the sleeve. When one end of the limiting rod located in the sleeve cooperates with the limiting groove under the action of threaded engagement, the sleeve and the pull rod are relatively fixed.

[0006] Furthermore, the pressing plate is circular, and the connection position between the sleeve and the pressing plate is located at the center of the pressing plate.

[0007] Furthermore, the limiting groove is an annular groove surrounding the axis of the pull rod, and the limiting rod is rotationally matched with the limiting groove.

[0010] Beneficial effects:

[0011] 1. In the utility model, by setting the sleeve, the pressure plate, the installation groove, the through hole, the spring and the limit assembly, the inner formwork and the outer formwork can be conveniently disassembled by utilizing the elastic force of the spring, thereby improving the disassembly efficiency and the construction quality. Specifically, during pouring, the sleeve is pulled along the pull rod by pulling the limit assembly, and the pressure plate is driven to compress the spring until the limit assembly and the limit groove are engaged. At this time, the spring is in a compressed state, and the pressure plate is flush with the surface of the inner formwork or the outer formwork to ensure that the concrete surface is flat. When the pouring is completed and the mold needs to be removed, and the inner formwork or the outer formwork is bonded to the concrete surface, the pressure plate slides out of the installation groove under the action of the elastic force of the spring and is squeezed against the concrete surface, thereby causing a certain looseness between the inner formwork or the outer formwork around the pressure plate and the concrete, or even causing it to completely separate, thereby effectively avoiding damage to the concrete surface caused by brute force removal.

[0012] 2. In the utility model, through the setting of the L-shaped support plate and the limit rod, the threaded engagement can be used to realize the coordination and separation of the limit rod and the limit groove, which is convenient and quick and can prevent the limit rod from loosening freely; the pressure plate is circular, and the connection position between the sleeve and the pressure plate is located at the center of the pressure plate, so that the sleeve can be subjected to nearly balanced forces in all directions, ensuring that it drives the pressure plate to slide more smoothly and labor-savingly; combined with the setting of the limit groove as an annular groove, the sleeve can always be rotated relative to the pull rod, so that during disassembly, the pressure plate can be quickly separated from the concrete surface through the shear force of rotation, and at the same time, it can also have a certain influence on the bonding force field between the inner formwork or outer formwork around the pressure plate and the concrete, further facilitating the disassembly of the inner formwork and the outer formwork, and improving the construction efficiency and quality.

[0013] 3. In the present invention, the inner chamfer and the outer chamfer are arranged to facilitate the matching of the limit rod and the limit groove.

[0014] 4. In the present invention, the sealing ring is provided to improve the sealing performance between the pressing plate and the installation groove, thereby preventing concrete from entering the installation groove during pouring. BRIEF DESCRIPTION OF THE DRAWINGS
