Abstract
The present invention relates to a method for suspending a guy cable of twisted steel cables for an oblique pulling bridge, which comprises the steps: 1) three parallel cables are suspended firstly, the positions of the three parallel cables are arranged at three periphery holes uniformly distributed on anchor plates, one end of each of the three twisted steel cables is fixedly locked on the upper anchor plate 2 by a clamping sheet 3 firstly, then the other end of each of the twisted steel cables 5 is fixedly locked on the lower anchor plate 9 by another clamping sheet 3, and the upper anchor plate and the lower anchor plate can be parallel; 2) other cables are suspended in sequences according to a sequence that the upper anchor plate 2 is suspended and penetrated firstly and the lower anchor plate 9 is suspended and penetrated successively, and each of the twisted steel cables is impressed with required force after being suspended and penetrated. The method can guarantee the contact surfaces of the upper anchor plate, the lower anchor plate, an upper bearing plate and a lower bearing plate to be parallel, and the subjected stress among all the twisted steel cables can be maintained uniformly.
Description
Technical field
The present invention relates to a kind of extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge, particularly a kind of extension Suo Fangfa of sheet clamping type group anchor guy of twisted steel cable.
Background technology
It all is to hang to wear under the situation that anchor slab does not have to fix up and down that the extension of sheet clamping type group anchor guy of twisted steel cable is in the past worn, stress application, at last anchor slab, down anchor slab is with last loaded plate, under loaded plate contact surface irrelevancy is capable down the situation, give in the steel strand application of force process, the angle of last anchor slab and last loaded plate contact surface changes, make steel strand pressure after angle changes of existing stress take place to reduce or increase, the inhomogeneities of suffered stress between each steel strand is increased, easily cause steel strand to rupture in advance.
Summary of the invention
The object of the present invention is to provide a kind of extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge, it can guarantee the contact surface keeping parallelism of upper and lower anchor slab and upper and lower loaded plate, and makes that suffered stress keeps evenly between each steel strand.
For reaching above-mentioned purpose, solution of the present invention is: adopt and to hang three parallel ropes earlier, its position on equally distributed three perimeter holes on the anchor slab, the method for formally hanging rope according to the order of sequence again.
Earlier an end of three steel strand is locked with intermediate plate admittedly at last anchor slab, then the other end of steel strand is locked with intermediate plate admittedly at following anchor slab.These three steel strand apply certain prestressing force for three steel strand at last anchor slab, be evenly distributed on the anchor slab down, the tension force of steel strand by intermediate plate, go up anchor slab, down anchor slab, go up loaded plate, loaded plate passes on tower or the beam down.Hang other rope afterwards again, the extension Suo Shunxu of other steel strand is: hang earlier and put on anchor slab, hang and wear anchor slab; Hang earlier and wear intermediate vertical one row's steel strand, again by from top to bottom order, about row hang steel strand symmetrically; Every extension has been worn steel strand, promptly in time applies desired power to it, wears until extension to finish.Each root steel strand hang wear finish after, mend again and execute prestressing force at first hanging three parallel ropes wearing.
The extension Suo Fangfa of the present invention's guy of twisted steel cable for cable stayed bridge, owing to there are three steel strand that evenly carry to be locked in admittedly on anchor slab, the following anchor slab, 3 of causes are fixed a plane, the fixed-site of anchor slab then, hang the suffered stress of steel strand wear stress application after making and exempt from rocking and change with anchor slab, the suffered stress of each steel strand is even, and easy fracture has not prolonged application life.
Description of drawings
Fig. 1 is the extension Suo Fangfa schematic diagram of guy of twisted steel cable for cable stayed bridge of the present invention.
The specific embodiment
Below, the feature to the present invention is described further in conjunction with the accompanying drawings and embodiments.
Shown in Figure 1, a kind of extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge.The steps include: 1) hang three parallel ropes earlier, its position is on equally distributed three perimeter holes on the anchor slab; Earlier three steel strand 5
1, 5
2, 5
3An end at last anchor slab 2 usefulness intermediate plates 3 solid locks, then steel strand 5
1, 5
2, 5
3The other end following anchor slab 9 usefulness intermediate plates 3 solid locks, so that make upper and lower anchor slab 9 keeping parallelisms; Give three parallel rope steel strand 5
1, 5
2, 5
3Apply certain prestressing force, steel strand 5
1, 5
2, 5
3Tension force by intermediate plate 3, go up anchor slab 2, down anchor slab 9, go up loaded plate 6, loaded plate 8 passes on tower 1 and the beam 7 down; 2) extension is worn other ropes according to the order of sequence: put on anchor slab 2 by hanging earlier, hang the order of wearing anchor slab 9 again, hang earlier and wear intermediate vertical one row's steel strand, press order from top to bottom again, about row hang symmetrically and wear (referring to accompanying drawing), every extension has been worn steel strand, promptly in time applies desired power to it, wears until extension to finish; 3) mend again and execute prestressing force at first hanging three parallel ropes wearing.
