What is turnover?

The turnover formwork refers to the tripod turnover formwork construction technology, which evolved from the traditional slip form and is now widely used in high pier construction. It is often encountered in the construction of cooling tower tube in power plant.

The lower part of the formwork is supported by a tripod supported by a mast. Slipform is used in the construction of chimney wall in power plant, and jack-up hydraulic device is needed as a tool to lift the formwork.

Matters needing attention

1, turnover formwork structure consists of construction platform, formwork system and auxiliary equipment.

2. There are four steel dies on the outside, which are internal dies with chamfers. The internal mold is divided into four pieces, and the chamfer is detachable. The inner and outer molds are tightened with wall tie rods.

3. Lifting equipment: mainly tower cranes and elevators, which are the main power equipment for transporting machines, tools and personnel.

4. The process flow of turnover formwork construction is: construction preparation → binding reinforcement → turnover formwork assembly → pouring concrete → lifting the working platform → lifting the formwork → construction to the pier top, dismantling the formwork → dismantling the working platform. During operation, formwork lifting, steel binding, concrete pouring and platform lifting are carried out in cycles.
