Abstract
A method for suspending the stay cable of steel strand for the cable-stayed bridge includes such steps as suspending three parallel ropes uniformly distributed to three periphery holes on anchor plate, fixing the one end of each of three stay cables to upper anchor plate by clamps, fixing their other ends to lower anchor plate by clamps making upper and lower anchor plates parallel, suspending other stay cables by passing them through upper anchor plate then lower anchor plate one by one, and applying required force to each stay cable after it is suspended. Its advantages are parallel contact planes of upper and lower anchor plates and upper and lower bearing plates, and uniform stress for all stay cables.
Description
The present invention relates to a kind of extension rope job practices of cable stayed bridge suspension cable, particularly a kind of extension Suo Fangfa of sheet clamping type group anchor guy of twisted steel cable.
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.
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.
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.
Below, the feature to the present invention is described further in conjunction with the accompanying drawings and embodiments.
Accompanying drawing: the extension Suo Fangfa schematic diagram of guy of twisted steel cable for cable stayed bridge of the present invention.
Embodiment
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 or the beam 7 down; 2) extension is worn other ropes according to the order of sequence: by extension is put on anchor slab 2 earlier, extension is worn the order of anchor slab 9 again, hang earlier and wear intermediate vertical one row's steel strand, press order from top to bottom again, about row wear (referring to accompanying drawing) to become claiming ground to hang, every extension has been worn steel strand, promptly in time apply desired power, wear until extension and finish to it; 3) mend again and execute prestressing force at first hanging three parallel ropes wearing.
Claims (3)
1, a kind of extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge is characterized in that: hang three parallel ropes earlier, its position hangs other ropes again on equally distributed three perimeter holes on the anchor slab; During construction, earlier three steel strand (5
1), (5
2), (5
3) an end at last anchor slab (2) with the solid lock of intermediate plate (3), then steel strand (5
1), (5
2), (5
3) the other end at following anchor slab (9) with the solid lock of intermediate plate (3), so that make upper and lower anchor slab keeping parallelism.
2, the extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge according to claim 1, it is characterized in that: the extension Suo Shunxu of other steel strand is: by extension is put on anchor slab (2) earlier, extension is worn the order of anchor slab (9) again, hang earlier and wear intermediate vertical one row's steel strand, again by from top to bottom order, about row wear becoming to claim ground to hang; Every extension has been worn steel strand, promptly in time applies desired power to it, wears until extension to finish.
3, the extension Suo Fangfa of guy of twisted steel cable for cable stayed bridge as claimed in claim 1 or 2 is characterized in that: each root steel strand hang wear finish after, mend again and execute prestressing force at first hanging three parallel ropes wearing.
