The bundle combining, knitting and lashing device is characterized by also comprising a bundle combing plate which is also provided with a plurality of through holes the diameters of which are slightly larger than the diameter of the steel strand; the through holes of the bundle combing plate are in one-to-one correspondence to the through holes of the drawing plug screws; and the bundle combining, knitting and lashing device also comprises a heading device which is communicated with a pump station. The utility model has the advantages that the whole bundle is convenient to draw and is easy to pass through a pipeline; the bound strand bundle is sorted and an anchorage device is correspondingly mounted after the whole bundle passes through, so that the strand bundle is plain and smooth and no phenomenon of mutual winding occurs; the bundle lashing efficiency is high and particularly the lashing time for a plurality of long bundles can be greatly saved; and each strand can be uniformly forced during stretching.
Description
Technical field
The utility model relates to the pre-stress construction facility, is specifically related to a kind of steel strand comb and compiles penetrating device.
Background technology
Early stage steel strand are reeved and are adopted single lashing method, cause that easily steel strand twine mutually, and steel strand are stressed seriously inhomogeneous when causing stretch-draw.At present, the general bridge particularly long-span beams body steel strand method of reeving generally adopts whole bundle (or grouping) lashing method, an end that is about to whole bundle (or several one group) steel strand welds together, entangle the termination with steel pipe again and weld together, form a heading, by being enclosed within the traction of the wire rope on the heading, (or direct and pull rope welding) makes whole bundle steel strand pass the prestressing tendon pipeline.Because heading is thick and rigidity is better, scratches crooked prestressing tendon pipeline in distraction procedure easily, particularly zinc-plated bellows squeezes a ball after scratching easily, causes steel strand to be blocked in the prestressing tendon pipeline.And last group difficulty of grouping is worn, and causes that easily steel strand twine mutually, even can't pass! The also whole bundle that has is worn (welding) but is dredged bundle, and particularly the ground tackle installation will aggravate twisted wire and beats strand.Therefore, the method for steel strand lashing and construction equipment need be improved.
Summary of the invention
The purpose of this utility model provides a kind of steel strand comb and compiles penetrating device, and it can make the steel strand integral bundle lashing carry out fast smoothly, and can guarantee that each single steel strand is stressed evenly, does not damage the prestressing tendon pipeline.
A kind of steel strand comb described in the utility model is compiled penetrating device, comprise traction plug screw, screw-casing, an end is connected haulage cable, is connected with the other end of haulage cable with screw-casing main rack winch with the cooperation of traction plug screw, be provided with the through hole of a plurality of slightly larger in diameter at the traction plug screw in the central hair diameter, it is characterized in that: comprise that also a comb bundle pulls, this comb bundle is pulled and also is provided with the through hole of a plurality of slightly larger in diameter in the steel strand diameter, and the through hole of the through hole pulled of comb bundle, traction plug screw all with corresponding ground tackle on the position, hole corresponding one by one; Also comprise a heading device, this heading device is communicated with pumping plant; Also comprise an auxiliary hoisting winding, this auxiliary hoisting winding is located on the end beam body of prestressing tendon pipeline.
Described a kind of steel strand comb is compiled penetrating device, and the distance between its each through hole of traction plug screw is slightly larger than the diameter of central hair; Via count on its traction plug screw is divided into 10-16 hole, 16-19 hole, 19-25 hole, the four kinds of forms in 25-30 hole, and pitch-row is 12mm; The via count that the comb bundle is pulled is corresponding with it.
Described a kind of steel strand comb is compiled penetrating device, and its described comb bundle is pulled to anchor and pulled or spacing pulling.
The utility model is compared with prior art and had the following advantages: the whole bundle of traction is very convenient, and the screw-casing size is little, and twisted wire bundle external diameter is close with tightening, and is easy to pass through pipeline; Unclog and readjust the twisted wire bundle after the colligation, after whole bundle passes, ground tackle is installed is sat in the right seat, make it smooth-going slyness, do not have mutual wrapping phenomena; Lashing efficient height especially can be saved the lashing time greatly to many long bundles; Stressed evenly in the stretch-draw with each single twisted wire of bundle.
