Ultra-long cantilever truss structure high formwork supporting system

An ultra-long cantilever truss structure high formwork supporting system is characterized in that an upper frame body and a lower frame body are included, the lower frame body comprises a structural steel cantilever beam, a lower-supporting structural steel bracket, an upwards-pulling steel wire rope and a lower frame concrete truss, the upper frame body comprises a load-bearing formwork base, an outer protection frame and an upper frame concrete truss, one end of the structural steel cantilever beam is fixed on the top of the lower frame concrete truss and stretches out of the top of the lower frame concrete truss, the bottom of the lower-supporting structural steel bracket is fixed in the middle of the lower frame concrete truss, the top of the lower-supporting structural steel bracket is fixed at the bottom of the cantilever beam, the lower-supporting structural steel bracket inclines from bottom to top in the stretching direction of the cantilever beam, the bottom of the steel wire rope is fixed on the top of the cantilever beam, the top of the steel wire rope is fixed at the bottom of the upper frame concrete truss, the top of the load-bearing formwork base is fixed on the upper frame concrete truss, the bottom of the load-bearing formwork base is fixed on the cantilever beam, and the outer protection frame is arranged on the outer side of the load-bearing formwork base. The ultra-long cantilever truss structure high formwork supporting system greatly improves construction efficiency, reduces investment of revolving materials, saves cost, enables erecting time to be reduced, and improves the unit time utilization rate of machinery and staff.
