After the perforate on anchor slab, fixed by bolt-nut, and branch sleeve, branch sleeve auxiliary connection threaded rod are set in its end
One end, the deputy thread bar other end pass through tensioning support, and are fixed on tensioning stent outer by tensioning nut;Tensioning nut with
Force transducer is additionally provided between tensioning support.
Wherein, screw shell one end is provided with longitudinal inner thread hole, and the other end is provided with horizontal unthreaded hole, longitudinal inner thread hole
For being connected with threaded rod, horizontal unthreaded hole is used for connecting steel wire ropes.
Wherein, after the horizontal unthreaded hole on screw shell, its end is extruded anchor head anchoring to steel wire penetrating.
Beneficial effect:A kind of prestress rope tensioning system of the present utility model, has the advantages that:
1st, many steel wire ropes can be anchored by one piece of anchor slab, substantially increases the reinforcing efficiency to existing structure and effect
Really;
2nd, can just realize applying steel wire rope prestressing force by rotating tensioning nut, and by controlling torsion reaching control
The stretching force of steel wire rope processed, it is convenient to construct, it is not necessary to main equipment, and cable tensios control high precision;
3rd, tensioning nut, pad, force transducer, branch sleeve and tensioning support are detachable and reuse, great Liang Jie
About reinforcement cost, and it is easy to use, install it is simple, rapidly and efficiently the characteristics of.
