What are the basic requirements when designing steel formwork

The function of the steel formwork of the bridge construction is to make the concrete members be poured into shape according to the designed shape and size; the supporting parts and fasteners are used to maintain the spatial design position of the formwork. For bridge construction steel formwork to have a long service life, it is necessary to standardize the operation during the design and meet the corresponding quality standards. The processing of every detail will affect the overall use effect. What are the basic requirements?

1. The safety accessories are complete, and the safety facilities and operating environment meet the requirements of the operation.

2. The self-designed template and its construction plan, operating procedures, etc. must be approved by the chief engineer of the unit.

3. It has sufficient strength, rigidity and stability, can reliably bear various construction loads specified in the formwork construction specification, and ensure that the deformation does not exceed the allowable range.

4. It is convenient to install and dismantle, and try to be standardized and serialized. If there are special requirements or complex operating procedures, the operating procedures should be formulated at the same time.

The steel formwork of bridge construction is a very important part of the forming of concrete members. Therefore, the rationality of the material selection and structure of the formwork and the quality of the formwork and installation directly affect the quality of the concrete structure engineering. Therefore, the steel formwork for bridge construction should pay attention to the above contents when designing, and it must be standardized in this link, so as to ensure the long-term use.
