Abstract
The utility model relates to a cable saddle used at the tower top of a suspension bridge. The cable saddle is characterized in that the tower top saddle is respectively provided with main cable anchoring points and a stay cable anchoring point. Two sides of the tower tope saddle are provided with the main cable anchoring points, and the middle of the tower top saddle is provided with the stay cable anchoring point. A main cable of parallel steel wire, after the cable release through a cable release sleeve, adopts a cast iron steel structure to be anchored at the main cable anchoring point of the cable saddle, and a stay cable adopts a welding structure to be anchored at the stay cable anchoring point. Therefore, the cable saddle has the advantages that on the one hand, the structure and the production of the saddle are simpler, and on the other hand, the complex process of the top push of the saddle is avoided. Meanwhile, the proposal can be adapted to the change of the main cable in a tridimensional plane.
Description
Technical field
The utility model relates to the bridge field, is specifically related to a kind of cable saddle that is used for the suspension bridge cat head.
Background technology
At present, conventional ground anchor type or the self-anchored suspension bridge structure of implementing striden main push-towing rope in its limit and is conitnuous forms both at home and abroad, realizes at cat head saddle place turning to.Saddle can adopt full casting structure, cast welding integrated structure or all-welded structure mainly to bear pressure.
During the construction and installation, the king-tower saddle must a pre-inclined to one side side, with drop in beam (stretch-draw hoist cable), operation such as mat formation, use jack stage by stage pushing tow reset.
The utility model content
The purpose of this utility model is to provide a kind of cable saddle that is used for the suspension bridge cat head, makes the structure of saddle and processing simpler.
In order to realize this purpose, the technical solution of the utility model is as follows: a kind of cable saddle that is used for the suspension bridge cat head, comprise the cat head saddle that is located at the king-tower cat head, and it is characterized in that this cat head saddle is respectively equipped with main push-towing rope anchor point and suspension cable anchor point.Cat head saddle both sides are provided with the main push-towing rope anchor point, are provided with the suspension cable anchor point in the middle of the cat head saddle.The parallel steel wire main push-towing rope adopts the cast steel structure anchor at cable saddle main push-towing rope anchor point after the noose that looses looses rope, and suspension cable adopts welded construction to be anchored at cable saddle suspension cable anchor point.
The utility model has constituted tangible technical characterstic by the such scheme feature, one, and cable disconnects at cat head, has reduced the processing length of main push-towing rope steel wire; Its two, end bay adopts suspension cable, stretch-draw has as required at any time made things convenient for construction control; Its three, it is flexible and changeable that member is formed, compliance is strong, strides main push-towing rope in promptly no matter in perpendicular or in three-dimensional inclined-plane, all can solve easily by the anchoring structure of cat head.Therefore, advantage of the present utility model is to make on the one hand the structure of saddle and processing more simple, has avoided the complicated technology of saddle pushing tow on the other hand.Simultaneously, this scheme can adapt to the variation of the main push-towing rope in the three-dimensional planar.

The specific embodiment
A kind of cable saddle that is used for the suspension bridge cat head shown in the figure comprises the cat head saddle 1 that is located at king-tower 7 cats head, it is characterized in that cat head saddle 1 both sides are provided with cable saddle main push-towing rope anchor point 2, is provided with cable saddle suspension cable anchor point 3 in the middle of the cat head saddle 1.Stride wherein parallel steel wire main push-towing rope 4 two ends respectively with cable saddle main push-towing rope anchor point 2 anchorings of two king-towers, suspension cable 5 one ends and 5 anchorings of cable saddle suspension cable anchor point, the other end is connected with the suspension bridge end bay.Parallel steel wire main push-towing rope 4 adopts the cast steel structure anchor at cable saddle main push-towing rope anchor point 2 after the noose 6 that looses looses rope, and suspension cable 5 adopts welded construction to be anchored at cable saddle suspension cable anchor point 3.
During the construction and installation, king-tower cat head saddle need not be inclined to one side in advance, with drop in beam (stretch-draw hoist cable), operation such as mat formation, uses jack stretch-draw end bay suspension cable stage by stage, guarantees that king-post is stressed within allowed band.
