Space steel truss suspension structure

A space steel truss suspension structure comprises a steel truss fixed between two adjacent building frame columns, a suspended ceiling is fixed to the bottom of the steel truss, a truss penetrating air pipe is arranged in the steel truss in a penetrating mode, the steel truss comprises at least two primary trusses and a plurality of secondary trusses fixed between the two adjacent primary trusses, and the secondary trusses are connected with the suspended ceiling. The main trusses are respectively fixed between two adjacent building frame columns, and fixing pieces for fixing the main trusses are fixed on the building frame columns. The steel truss is additionally arranged below the building floor and used for bearing the load of the suspended ceiling, the building floor of the floor does not bear the load of the suspended ceiling, the two ends of the steel truss transmit axial force through the building frame columns, and therefore the stability of the building floor and the stability of the building struct
