The principle of choose bridge steel formwork

1. Ensure that the shape and size of the bridge steel formwork components are correct.

2. Ensure that the strength, stability and rigidity of the bridge steel formwork are sufficient to withstand the weight, lateral pressure and various construction loads of the newly poured concrete.

3. The selected bridge steel formwork should be as large as possible. It must also be ensured that it is a universal template. When installing the steel formwork, you need to choose a tightening bolt. The use of flat-cut square timber instead of bolts can reduce the loss of drilling in the steel formwork of the bridge.

4. Ensure that the bridge steel formwork is simple in structure, convenient to load and unload, and does not affect the subsequent bonding of steel bars. When injecting concrete, you need to make sure that there is no grout leaking.

5. After the bridge steel template is matched with the plate, the corresponding plan view of the plate needs to be drawn to accurately mark the position and size of the steel template. If you want to pre-install large-scale bridge steel formwork, you need to mark the dividing line. The layout drawing of the steel formwork of the bridge shall indicate the position of the embedded body and the reserved holes as much as possible, and indicate the fixing method.

6. For the splicing of the long sides of the bridge steel formwork, the staggered arrangement must be selected. The main purpose is to increase the overall rigidity of the formwork.
