Structure and Types
Self - climbing formwork

It can climb upward automatically, suitable for high - rise pylon construction. It can improve construction efficiency and quality, and reduce the risk of high - altitude operations.

The formwork is disassembled and reassembled section by section from bottom to top. It is simple in structure and easy to operate, but the construction efficiency is relatively low, which is suitable for the construction of tower columns with relatively low heights.
Working Principle

- Installation: First, the formwork panels are assembled according to the design size and shape, and then the supporting system and connection parts are installed. The formwork is hoisted into position by a crane and adjusted to the correct height and position.

 

- Concreting: After the reinforcement is placed, the concrete is poured into the formwork. During the concreting process, the formwork bears the pressure of the concrete and maintains its shape and position.

 

- Demoulding: After the concrete reaches the required strength, the connection parts are removed first, and then the formwork panels and the supporting system are removed in sequence.

 

Composition

 

- Formwork panels: Usually made of steel plates, they have high strength, good durability and smooth surfaces, which can ensure the surface quality of the tower columns.

 

- Supporting system: Composed of soldiers, jacks, etc., it is used to bear the pressure of the formwork and concrete and adjust the height and position of the formwork.

 

- Connection parts: Such as bolts and nuts, they are used to connect the formwork panels and the supporting system to ensure the integrity and stability of the formwork structure.


Advantages
01
Strength, stiffness and stability
It should be able to withstand all construction loads to ensure that the deformation does not exceed the allowable range.
02
Accuracy
The manufacturing and installation accuracy of the formwork should be high to ensure the dimensional accuracy of the tower columns.
03
Ease of operation
It should be easy to install, disassemble and move to improve construction efficiency.
