Overall tensioning system for pre-tensioning method pre-cast beam plate
The invention belongs to an overall tensioning system for a pre-tensioning method pre-cast beam plate. The overall tensioning system is composed of a pedestal, a stranded steel wire, a jack and a tensioning oil pump; and the overall tensioning system comprises a middle structure, a left structure and a right structure. The pedestal in the middle structure is arranged between two L-shaped butted tension transfer columns, the stranded steel wire for preparing the pre-tensioning method pre-cast beam plate is arranged on the pedestal, and an anchoring end steel transverse beam and a tensioning end steel transverse beam are located at the outer ends of the two ends of each tension transfer column. Steel plates are arranged between the anchoring end steel transverse beams of the left structure and the lateral faces of the tension transfer columns on the corresponding sides, the outer lateral faces of the anchoring end steel transverse beams are provided with anchoring limiting steel plates, and one end of each finish rolling thread connecting rod at the end of each anchoring limiting steel plate penetrates a puncture hole in the corresponding anchoring limiting steel plate to be connected with a corresponding nut. The other end of each finish rolling thread connecting rod penetrates the corresponding anchoring end steel transverse beam to be located on the outer side of the pedestal, and anchoring end connectors are arranged on the finish rolling thread connecting rods. The overall tensioning system has the beneficial effects of being simple and practical in structure, good in efficiency and quality, low in production cost, safe in use and good in using effect.
