The components with the symmetrical surfaces are symmetrically arranged before concrete pouring, the reinforcing steel bar system is arranged in the components to form a cavity, and the components are called concrete cavity components for short and comprise concrete walls, columns, beams and the like. The main function of the formwork is to restrain the concrete formation, and the formwork is divided into a detachable formwork and a non-detachable formwork. The detachable formwork is generally used in combination with the expansion-proof formwork back edge and the split bolt, and the detachment-free formwork is a new emerging process in recent years, namely: the concrete and the template are formed together without separation.

The concrete member forming process comprises the following steps: generally, the method comprises the steps of binding a steel bar system, supporting a template, pouring and curing concrete, and forming a member. It should be noted that the steel bar system can not be tightly attached to the formwork, and a concrete protective layer is required to be arranged to ensure that the steel bars are not exposed and rusted, and the size of the protective layer is determined by design and is generally 15mm to 35 mm.

4. the component precision is difficult to guarantee.

2. Factory prefabrication and molding: the method needs to be completed on a special die table, and comprises the following steps: and (3) binding the side forms of the upper component of the mould platform and a reinforcing steel bar system, placing a concrete protective layer cushion block, pouring concrete, curing and forming, turning the semi-finished component, supporting the side forms, pouring concrete again, curing and forming, and forming the cavity concrete component.

Prefabricating a factory, namely, removing the hollow shell without formwork, and performing secondary casting molding on site: the method is a novel building industrialized production mode and comprises the following steps: the method comprises the steps of steel bar system integration, steel bar cage built-in anti-expansion mould back ridges, protective layer cushion block binding, straight anchor face templates, cavity components delivery, on-site assembly and preparation of a support system, concrete pouring, maintenance forming and template dismantling or dismantling-free.

The technical defects of the structure and the process are as follows:

1. special equipment is required;

2. the forming process is complicated, the efficiency is low, and the manufacturing cost is high;

3. the forming precision of the prefabricated part is difficult to ensure;

4. prefabricating a factory, namely, removing the hollow shell without formwork, and performing secondary casting molding on site:

5. the reinforcing steel bar system is flexible, and the forming precision is difficult to ensure;

6. the position of the built-in back edge has errors, the foundation of the straight anchor is unstable, and the deviation is determined to exist in the forming process;

7. and no support exists between the symmetrical templates, and errors can be generated on two surfaces when the anchor is straightened.
