It can be used for traditional construction methods, as well as new industrialized construction methods such as formwork-free systems, prefabricated assembled buildings, and steel structure buildings; it is suitable for building structures such as frame structures, shear wall structures, frame shear wall structures, and steel structures. The floor-standing assembled formwork system is generally divided into three parts: working platform, climbing frame, and lifting column. The working platform includes a steel platform, a truss platform, an operating platform, and the like.
