The small square steel formwork support system, also known as the new shear wall formwork support system, is a new type of formwork support system, mainly composed of the main and secondary small square steel keels. The materials are all made of high-quality cold rolled steel series, and the formwork is stable and not easy to deform and twist. Compared with traditional wood formwork support systems, it has many advantages, such as: high qualification rate of wall flatness and verticality, simple construction, easy operation, strong and durable Long service life and other advantages.

Although traditional wood formwork support systems are easy to process and have low one-time investment costs, they are less frequently used, easy to deform, and have poor aesthetic appearance on the wall surface, requiring secondary plastering, increasingly not meeting the requirements of engineering quality.

Steel pipes and timbers have become difficult to meet construction needs, and workers need to cut according to wall thickness, wall length, and wall height. When several floors are down, the wood becomes shorter and shorter, and the steel pipes are also cut, resulting in higher construction costs and difficulties in storing construction waste on the construction site. When pouring and tamping concrete, due to wet expansion and dry shrinkage of timber, improper handling can easily warp and crack, resulting in formwork expansion, section bulge, slurry leakage, and other phenomena. It is also easy to cause the poured concrete to not be formed as designed in advance.

The combination of steel pipes and wooden squares has insufficient fixation effect on the openings and inner and outer wall corners of the shear wall, resulting in unclear corners of the poured wall corners, which is prone to mortar leakage. The mechanical properties of square timber and steel pipes differ greatly, and often there is a phenomenon of formwork shifting caused by deformation at the contact point with the steel pipe when the square timber is under pressure. It is difficult to ensure the construction quality, and workers need to repair it later, which not only wastes labor, but also affects the progress of the construction period. Wood is not environmentally friendly and has few turnover times, resulting in a waste of resources and a significant increase in costs.

The small square steel support system can avoid these shortcomings of steel pipes and wooden beams, so it is popular among builders in construction. It improves the strength of formwork reinforcement, eliminates distortion, mortar leakage, and waste of building materials, responding to the national idea of promoting environmentally friendly building materials.
