At present, although this system is widely used in construction sites in China, it also has some typical shortcomings, such as high cost, serious waste, insecurity, instability and difficulty in adjustment.
The wall made by this method also has a disadvantage that it is not flat enough, and slurry leakage often occurs. Especially in the hole and corner, the template fixing is very troublesome.
Because of the above problems in the traditional way, someone has developed a new shear wall support system, which can fundamentally subvert the traditional construction technology. The characteristics of this method are as follows:
The main back stare blankly is welded by two square pipes with the same cross section size. After installing the through-wall bolts during construction, only one person needs to pick up the main back stare blankly horizontally and lock it on the bolts.
This method is not only time-saving and labor-saving, but also because the secondary ridges used with it are all steel square structures, so the stress on the joint surface is more uniform and the construction effect is good. Nowadays, many houses are short-leg shear wall structures, and the last displacement of the wall can adjust the main back, so it can adapt to various architectural needs. No matter how big the shear wall and hidden column are, they can provide it with stable and beautiful support. This support method is firm, and the effect and quality after formwork removal are first-class, which greatly improves the engineering quality. Due to the use of square steel to strengthen the structure, all components are standardized and modular, which can be used for turnover and multiple projects, and the turnover times can exceed 300 times, which well solves the problem of ultra-high cost of wood square.
Another advantage is that cold-rolled steel has corrosion resistance, elasticity and high bearing capacity. After passing through the through-wall screws and cross washers, it will not expand with heat and contract with cold due to weather and temperature changes, which greatly ensures the flatness of shear walls and columns. The corners and openings are the best places to deal with the formwork support of the new shear wall. The design of this corner clamp solves the problems often encountered in the traditional shear wall support system. It not only ensures the edges and corners, but also avoids the occurrence of slurry leakage and slurry leakage at corners.
Therefore, using this new formwork support method in the construction site can greatly improve the construction efficiency and quality, and also make "
