Description
Technical field
The utility model is related to a kind of multi beam prestress wire lashing banding draft gears, belong to architectural engineering technology neck
Domain.
Background technology
In continuous beam construction, traditional prestress wire lashing is generally integral by the welding of steel strand wires end, then welds
Reinforcing bar draw ring is connect, then lashing is carried out using hoist engine.In this mode kind, the strength of parent for destroying steel strand wires is welded in end,
Later stage need to carry out end portion the cutting of certain distance.Further, since steel strand wires are long, overweight, welding is caused to be drawn
Head easily pulled, cause steel strand wires can not lashing, the quality and lashing efficiency of steel strand wires can not ensure.
In existing public technology, such as publication number：CN103938874 B《A kind of prestress wire lashing draft gear and
Construction method》It describes using silk pier nose progress steel strand wires whole strand pricking in steel strand wires, the preferable lashing of technology energy, but in steel
Injury is easily caused when silk is removed in twisted wire, and only silk causes the risk that silk pulls in steel strand wires in traction.
