Self-sustaining load tensioning system of double-row tensioning steel beam

The invention belongs to the technical field of prestressed member tensioning pedestals, and particularly relates to a self-sustaining load tensioning system for double-row tensioning steel girders, the self-sustaining load tensioning system for the double-row tensioning steel girders comprises a prestressed member forming module, and bearing columns are symmetrically arranged at the ends of the prestressed member forming module; a steel beam anchoring unit is arranged on the side part of the bearing column; a component bottom die unit is arranged in the prestressed component forming module; a base anchoring unit is arranged at the lower part of the prestressed member forming module; compared with the prior art, the self-sustaining load tensioning system replaces a traditional concrete foundation pouring mode, the tensioning force is borne by means of the strength and compression resistance stability of equipment, the construction process is more convenient, expandability is higher, the construction cost is r
