Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a novel municipal administration way bridge pretension method prestressing force is put construction device, including first stretch-draw crossbeam 1, second stretch-draw crossbeam 2, third stretch-draw crossbeam 3, the cylinder body 4, the movable plate 5, first stretch-draw crossbeam 1, second stretch-draw crossbeam 2, guide slot 6 has all been seted up to 3 inner walls of third stretch-draw crossbeam, guide slot 6 is inside all to be equipped with a plurality of guide blocks 7, perforation 8 has been seted up at guide block 7 middle part, 7 one end of guide block is equipped with steel strand wires anchor clamps 9, one of them first stretch-draw crossbeam 1 right-hand member is equipped with guide arm 10, a plurality of scale marks 11 have been seted up to guide arm 10 upper end, spout 12 has been seted up to guide arm 10 front end, spout 12 is inside to be equipped with slider 13, slider 13 front side left end is equipped with switch 14, the inside lead screw 15 that is equipped with of guide arm 10. The steel strand clamp 9 is the same as in the reference.
