Description

A shear wall formwork in structural joint

Technical Field

The utility model relates to the technical field of shear wall formworks, in particular to a shear wall formwork in a structural joint.

Background Art

A shear wall is a structural wall used to withstand horizontal loads (such as earthquakes or wind loads). Its main function is to increase the stability and seismic resistance of a building by bearing and dispersing loads. Shear wall formwork is used during the construction of concrete shear walls. Shear wall formwork is a special building formwork used for the construction of shear walls.

The prior art has the following deficiencies: During the construction process, in order to avoid the influence of factors such as temperature expansion and contraction, foundation settlement and earthquake collision as much as possible, it is usually necessary to set a structural joint between two adjacent buildings or two parts of a building. When constructing the concrete shear walls on both sides of the structural joint, due to the adhesion between the concrete and the shear wall formwork, the traditional shear wall formwork needs to apply a large force when dismantling and demolding. The width of the structural joint limits the traditional force application method, resulting in the problem that the shear wall formwork in the structural joint cannot be normally demolded and removed without being damaged.

Therefore, it is necessary to invent a shear wall formwork in a structural joint.
