[0001] The invention relates to the technical field of single-side formwork structures, in particular to a single-side formwork structure with secondary docking. Background Art

[0002] In a single-sided formwork structure, multiple independent formworks are usually used for support. When the length of a formwork is insufficient, two formworks need to be connected together through secondary docking to form a long formwork to support concrete pouring. The secondary docking needs to ensure the firmness and stability of the connection point to prevent the formwork from tipping over or collapsing during construction, thereby ensuring construction safety and quality. However, in the prior art, it is necessary to adjust the inclination angle of the formwork according to the inclination angle of the building. After the inclination angle is adjusted, the angle of the outer support column also needs to be adjusted to avoid a decrease in the bearing capacity of the support column. However, in the existing structure, the support columns are mostly fixed, which makes it impossible to quickly adapt after adjusting the inclination of the formwork. Summary of the invention
