Roll the supporting component of screw-thread steel 3；The hexagonal (hexagon)nut 2 of repacking meets bottom 4cm internal diameters and the external diameter hexagonal matching of nut 1, ensures
The synchronous rotary of fining twisted steel 3 when the hexagonal (hexagon)nut 2 of repacking rotates, length according to condition of construction ensure after installation with concrete top
Face flushes；Spanner 7 selects live welded steel, and front end matches with the hexagonal (hexagon)nut 2 reequiped, and it is a fold-line-shaped to pull handle, full
Foot operation requires.
Tensioning base 5 is welded by 2cm steel plates, meets tensioning requirement for bearing capacity, and middle reserving hole meets 32 finish rolling spiral shells
Line steel 3 passes through.
Connector 4 is the component supporting with 32mm fining twisted steel 3.
The hexagonal (hexagon)nut of repacking, meet bottom 4cm internal diameters and the external diameter six of nut 1 while internal diameter passes through fining twisted steel 3
Side shape matching.
The advantages of the utility model：
Vertical prestressing tensioning equipment described in the utility model, pedestal use live welded steel, convenient material drawing, welding
Simply, construction cost is low.It is directly fixed using tower crane lifting installation during use.By reequiping hexagonal (hexagon)nut, spanner is made
Turn height with position, convenient operation, solve vertical prestressing and occupy the difficulty that most of space nut screws limited space with nut
Topic.Avoid and dig out concrete waste of time, the drawbacks of causing a hidden trouble is produced to construction quality.Same work is completed in each circulation
Amount, save the time of chisel concrete and cleaning, efficiency improves 3-5 times, can accelerating construction progress, reduce auxiliary of constructing and set
Standby power consumption, has saved cost of labor, from duration, economic dispatch angle analysis, has dissemination.It is easy to operate, jack
Occur loss of prestress after returning back to top to greatly reduce, bridge construction is made potential safety hazard and effectively eliminated.
