Abstract
The utility model provides a binding pulling device of a prestressed steel strand. The binding pulling device comprises a bearing plate, an adapter coupling nut and a tapered pulling head; the bearing plate is arranged at the tail part of the pulling device and used for connecting and pulling a medium wire of the steel strand; the adapter coupling nut is arranged in the middle part of the pulling device and used for connecting the bearing plate and the tapered pulling head; the head part of the pulling device is the tapered pulling head and used for connecting a pulling steel wire rope; the bearing plate, the adapter coupling nut and the tapered pulling head are mutually engaged and connected through screw threads. The binding pulling device is simple to process and manufacture, and convenient to operate on site; a pier head is limited to the bearing plate through a medium straight wire of the steel strand, the tapered pulling head is used for pulling, the adapter coupling nut is used for connecting; the design is flexible, and the operation is convenient; the processing can be carried out according to prestressed steel beams of different quantity; the pier head is pulled through the medium straight wire of the steel strand, thus the problem that the steel strand is difficult to bind by the traditional mode can be effectively overcome, new problem of binding overlong, overweight and overmuch steel strands can also be overcome, and the speed of binding the prestressed steel strand is greatly raised.
Description
Technical field
The utility model relates to a kind of prestress wire lashing draw-gear.
Background technology
Traditional steel stranded wire penetrating adapter in pre-stress construction links without corresponding code requirement, in weak link, in construction, the general steel strand traction termination that adopts adopts electric welding or oxygen welding welding, destroy steel strand mother metal characteristic, easily cause quality, potential safety hazard to pre-stress construction, cost is higher, long construction period.Prestress wire strand pulling machine is comparatively expensive, and cannot effectively solve overlength, overweight, super multiply is counted a steel stranded wire penetrating adapter difficult problem.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome above-mentioned background technology, a kind of prestress wire lashing draw-gear is provided and wears delivery method, guarantees steel stranded wire penetrating adapter quality and safety.
The technical solution of the utility model is: a kind of prestress wire lashing draw-gear, it comprises: loaded plate, switching nut, taper drawing head, described prestress wire lashing draw-gear afterbody is loaded plate, middle part is switching nut, head is taper drawing head, and described loaded plate, switching nut, taper drawing head are connected mutually by screw thread.
Described loaded plate is used for connecting traction steel strand; Thickness minimum is 25mm, is 50mm to the maximum; Diameter is minimum with respect to bellows is 30mm, is 40mm to the maximum; Loaded plate perforate arrangement form is with ground tackle form, and aperture is δ=6mm, and for convenience of using, the positive processing of loaded plate is regular hexagon.
Described switching nut is used for connecting loaded plate and taper drawing head, adopts form of annular rings, and wall thickness minimum is 10mm, is 20mm to the maximum; Inner side screw thread is used for connecting loaded plate, and outside screw thread is used for connecting taper drawing head.
Described taper drawing head is used for connecting haulage cable, adopts conical form, and inner side screw thread is used for connecting switching nut, and rear end arranges circular hole, connecting steel wire ropes.
The beneficial effects of the utility model are: the utility model processing and manufacturing is simple, and execute-in-place is convenient, adopt the middle raw silk rings pier nose of steel strand to be constrained in loaded plate, the traction of taper drawing head, switching nut connects, flexible design, easy to operate, can process according to different number of share of stock prestressed strands; Adopt raw silk rings in steel strand to carry out pier nose traction, effectively solve a traditional steel stranded wire penetrating adapter difficult problem, while has also solved overlength, overweight, super multiply is counted the newborn difficult problem of steel stranded wire penetrating adapter, greatly improve prestress wire lashing speed, effectively ensure lashing quality and safety, and reduced significantly construction cost, formed and provide steel stranded wire penetrating adapter construction normative reference, the construction technology process meaning with specification steel stranded wire penetrating adapter, has better application prospect.
