Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a tie-rod-free single-side cantilever formwork support structure. Background Art

[0002] The single-sided cantilever formwork inclined bracket plate structure is a support component structure used in construction. It is usually used to support the component concrete formwork to provide support components when pouring concrete. This structure is common in situations where construction needs to be carried out on one side, such as in the construction of slopes, bridges or high-rise buildings. The design of this support component structure allows the side that needs construction to be cantilevered a certain distance to provide sufficient space for construction workers, while supporting the component concrete formwork to ensure safe and efficient construction and the quality of concrete pouring. At the same time, it also helps to protect the safety of workers because it provides a stable working platform.

[0003] However, in the process of realizing the embodiments of the present invention, the inventors found that there are at least the following defects in the background technology: the existing single-sided cantilever formwork support structure is inconvenient to install, the formwork operation is complicated, and due to the presence of tie rod holes, the wall's self-waterproofing performance is poor and the formwork does not have an angle adjustment function, which affects the stability of the overall structure. Therefore, we propose a tie rod-free single-sided cantilever formwork support structure to solve this problem. Utility Model Content
