[0002] With the increasing number of super high-rise buildings, in order to meet the effect of highlighting the building facade shape during architectural design, designers often design some cantilever structural components that are difficult to construct in the pursuit of beautiful appearance and unique shape in super high-rise design. This brings certain difficulties to the construction of the cantilever structure formwork support system.

[0003] At present, most of the existing construction methods are difficult, the construction process is difficult to master, the structure is too complicated, the assembly and disassembly are cumbersome, and the safety and reliability are relatively low. Due to the long cantilever length, high floor height, large component load, high height of the cantilever structure component formwork frame, poor ultra-high stability, the cantilever structure component is easy to deform, and the forming effect is poor. For this reason, we propose a detachable hinged support steel structure support system. Utility Model Content

[0006] Preferably, a movable supporting square steel is arranged inside the angle between the I-beam and the diagonal bracing square steel, and both ends of the movable supporting square steel are movably connected to the I-beam and the diagonal bracing square steel respectively through end hinge supports.

[0007] Preferably, the force unloading support is composed of a plurality of transversely installed I-beams, and the bottom of the force unloading support is fixedly installed on the top of the first cantilever platform through embedded parts.

[0008] Preferably, angle steels are provided on both sides of the I-beam inside the force unloading support, and both ends of the angle steels are fixedly connected to adjacent I-beams by welding.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The use of segmented construction of cantilever structures can effectively solve the problems of high height of the cantilever structure formwork frame, poor ultra-high stability, easy deformation of cantilever structure components, and poor forming effect. The concrete structure is constructed in segments, and the load is applied in stages, reducing the load on the steel platform.
