Background technique

Jacking is a commonly used force-bearing component in the construction field. It is widely used in the bracket formwork system of cast-in-place concrete in housing construction, municipal and bridge engineering. Its function is to directly bear the load of formwork system, cast-in-place structure and personnel and equipment. It can also be used as a support member in the foundation pit and formwork to prevent deformation by taking advantage of its good supporting capacity.

With the development of architectural aesthetics, more and more special-shaped structures are used in construction projects, and there are more new requirements for formwork support systems. At present, the mainstream jacking products on the market are all at a horizontal angle. The common process used in the face of inclined structures is to adjust the height of the horizontal jacking according to the slope of the structure, and place wooden squares or shaped steel backs on the jacking. However, due to the They are all straight-line structures, and can only be in line contact with the top surface of the jacking, but cannot achieve surface contact. Therefore, after the back flute is installed, wooden wedges must be placed between the gap between the back flute and the top surface of the jacking. Increase the bearing area. This process consumes a lot of labor time and wastes a lot of resources. At the same time, due to the unreasonable processing size of the wooden wedge, it is impossible to realize the effective surface contact between the back flute and the top surface of the jacking, resulting in jacking or backing caused by concentrated force. The corrugated deformation will directly damage the components in severe cases.
