The existing formwork support frame is mostly made of wooden bar or iron pipe, and its height is not adjustable due to its size. In order to solve the above problems, the formwork support frame comprises a telescopic sleeve, a screw, a threaded seat and a bolt, and the threaded seat is sleeved or inserted and circularly sliding at the end of the telescopic sleeve; The screw is matched with the threaded through hole in the center of the threaded seat; A plurality of longitudinally distributed through holes are opened on the pipe wall of the telescopic sleeve, and the inner diameter of the through hole is greater than the outer diameter of the bolt. After adopting the above scheme, the telescopic sleeve, through hole and bolt are its primary expansion, and its height can be roughly adjusted through the cooperation of the three; The screw rod and the screw seat are two-stage telescopic, and their height can be fine adjusted with the cooperation of the two. Because of its adjustable height, it can meet the requirements of various landforms; When the foundation is soft and sinking, the height of the formwork and the concrete in it can be readjusted only by rotating the threaded seat. It is widely used in the pouring of various concrete under different landform and geological conditions.

The above is the traditional formwork support frame, which is now using the formwork support system or the new formwork support system in 2022, which is the upgrading of the formwork support system. The new building formwork support system has the advantages of energy saving, material saving, cost saving, ensuring project quality and improving construction efficiency. It can be recycled, with high strength and good perpendicularity and flatness of concrete. It has implemented the basic national policy of energy conservation and emission reduction, which is beneficial to the country and the people. It is the welcome truth of the new formwork support system.

The characteristics of the new shear wall formwork support are as follows

1. The frame is stable and firm, with strong bearing capacity and high safety factor;

2. Low unit cost and small steel consumption, only 15kg;

3. The disassembly and assembly steps are simple and do not need professional and technical workers. Ordinary workers can see it at a glance, which is in line with the operating habits of workers;

4. The external image of the project is clean and tidy to improve the popularity of the enterprise.

The new formwork support system has the following advantages:

1、 "Replacing wood with steel", the part of the new formwork support system instead of wood square is composed of retractable main keel and auxiliary keel. The main keel can be retracted freely. It is suitable for support of any size, with high turnover and utilization rate and strong universality.

2、 The connection between the vertical rod and transverse tie rod of the new formwork support system replaces the traditional steel pipe fastener scaffold. It has the advantages of simple installation and disassembly, and the construction speed is 8-10 times that of the traditional steel pipe fastener scaffold. It not only saves labor, but also shortens the construction period.

3、 The new template supports the standardization, structure, beautiful and tidy construction site of the components used, which not only improves the overall image of the project, but also reflects the strength of the engineering enterprise.
