Let's first understand several conceptual concepts, the concept of concrete structure: it is a structure mainly made of concrete, including plain concrete structure, reinforced concrete structure and prestressed concrete structure. The cast-in-place structure is formed by formwork erection on site and integral pouring.

The formwork structure is a temporary structure, which is made according to the design requirements, so that the concrete structural members are formed according to the specified position and geometric size, maintain the correct position, and bear the self weight of the formwork and the load acting on it.

The composition of formwork support system: panel, support, support and connector.

It is said that it is a rapid formwork support system, which is determined by its advantages.

1. Good molding effect.

The new steel support system has high strength and stability, and the solid reinforcement system can eliminate the rising mold, slurry leakage and structural deformation.

2. Low cost.

The turnover times of the new steel support system can reach more than 300 times, with low single use cost and high residue rate.

3. It is conducive to safe and civilized construction.

The new steel support system is used for construction. After demoulding, there is no garbage, rust, fire hazard, chain saw residual wood pins and other construction waste on the site. The construction site is clean and meets the green building construction standards.

4. The technology is simple and the operation is simple.

The new steel support system is easy to install, operate and learn. When installing, just carry out simple training, and anyone can install it.

5. High construction efficiency and short period.

Compared with the traditional formwork steel support system, the new formwork steel support system has high construction efficiency, which can greatly shorten the construction period, save management costs, and shorten the development cycle of real estate developers.

6. Wide application range.

The steel support system is applicable to all shear wall structures, frame shear structures, frame structures and wall columns.

Quality control of formwork support system:

1、 Control through calculation: according to the existing structural specifications and the actual situation of the construction site, the technicians of the project department

The strength, stiffness and stability of the formwork support system must be checked and calculated.

2、 Control through structural reinforcement:

1. Add horizontal connecting rod

2. Vertical and horizontal sweeping rods are set at the bottom

3. Set continuous diagonal bracing

4. Increase the section of upright

3、 Carry out mandatory control from the supervision and management system:

1. Implement a strict system of preparation, examination and approval

2. The content of the construction scheme shall be clearly required:

① Calculation sheet must be provided for formwork support

② Detailed structure drawing

③ Construction procedures, schemes and safety measures for fabrication, installation and demolition

④ After the installation of formwork works, it shall be inspected and accepted according to the design requirements
