Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a formwork support structure for shear walls. Background Technique

[0002] Shear walls are also known as wind-resistant walls, seismic walls or structural walls. They are the main walls in buildings or structures that bear the horizontal loads and vertical loads (gravity) caused by wind loads or seismic actions, preventing the structure from shear (shearing) failure.

[0003] Before the formwork support project of shear walls, the formwork support system should be designed and calculated. During the installation process of the formwork and its supports, temporary fixing facilities to prevent tilting must be set up. Different formwork support structures are required for different shear walls, which requires recalculation and design, consuming a large amount of manpower, material resources and time; for some relatively high formwork structures, there is a risk of instability, tilting and collapse during the pouring process. Based on this, a formwork support structure for shear walls is proposed. Content of the Utility Model
