Description

Technical Field

[0001] The utility model belongs to the technical field of formwork support, and particularly relates to a building formwork structure. Background Technique

[0002] In building construction, the formwork project is a key step to ensure that the concrete structure is formed according to the design requirements. The formwork support is a formwork fixing frame, a frame for supporting the building formwork, which is used to enhance the anti-deformation function of the formwork. The traditional building formwork structure usually includes a side support system for fixing the building formwork, a bottom foot, and a diagonal brace member. These components work together to maintain the stability of the formwork, prevent it from deforming or shifting, and at the same time bear the loads during the construction process.

[0003] However, there are some deficiencies in the existing building formwork technologies. For example, when adjusting the lateral clamping force, it is often necessary to hammer the diagonal brace, which is not only complex in operation but also difficult to position, resulting in low construction efficiency and increased safety risks. In addition, once the position of the diagonal brace is adjusted, its stability often cannot be guaranteed, affecting the accuracy and reliability of the entire formwork system.

[0004] In view of the limitations of the existing technologies, there is an urgent need for a building formwork structure that can provide fast, stable and adjustable performance to improve the construction efficiency, ensure the project quality, and reduce the construction cost. For this reason, this application document provides a building formwork structure. Summary of the Utility Model
