Concrete bracket structure replacement truss column supporting system

The invention provides a concrete bracket structure replacement truss column supporting system, and belongs to the technical field of building construction. According to the technical scheme, the device comprises a plurality of main truss columns, the main truss columns are sequentially connected and built through bolts from bottom to top, the top of the main truss column at the uppermost end is connected with a top truss column through bolts, and a hydraulic jack is arranged on the top truss column. The construction method has the beneficial effects that the problems that an existing floor type steel pipe fastener all-round scaffold supporting system is high in construction cost, long in period, large in potential safety hazard, complex in erecting process, high in supporting stability requirement, capable of influencing the upper-layer bracket replacement and reinforcement construction progress and the like can be effectively solved, and on the premise that safety is guaranteed, the construction efficiency
