Description
Technical field
The utility model belongs to civil works building technology field, specifically relates to a kind of main rope tower structure of suspension bridge of the not slippage of middle Tasso thigh that is applicable to the large-span multi-pylon cable suspension bridge.
Background technology
Bridge construction on coastal broad gulf mouth or the straits between Li Island and the land; The Foundation Design that has on the bridge if desired in multidirectional air route or the water is relatively more difficult excessive with cost; Adopt the structural concept of multitower multispan suspension bridge; This scheme not only rationally with is economically economized technically, can reduce density that bridge pier stands in great numbers again and to the adverse effect of water area ecological environment.Compare with the double tower single span suspension bridge that adopts middle main span one to stride across; The multispan suspension bridge can reduce main span greatly and stride the footpath; Significantly reduce tension of main cable and anchorage scale, its comprehensive cost decreases, thereby in the construction of long-span bridge beam, has stronger competitiveness.
Though all be to be the bridge of major bearing structures with the suspension cable and since the multitower suspension bridge than two tower suspension bridges many a main span, its general structure behavior, satisfy such as instructions for uses such as driving functions, all inequality with two traditional tower suspension bridges.King-tower is at vertical just vertical fulcrum of fixing through saddle and supporting main push-towing rope in the three tower suspension bridges.When uneven pulling force appearred in a side main push-towing rope, the part that it can be born need lean on the frictional resistance between main push-towing rope and the saddle to be used for realizing, the choosing of middle tower longitudinal rigidity need take into account said girder deflection span ratio, main push-towing rope and in antiskid moves between main saddle, middle tower is stressed.Since the constraint of middle column overhead a little less than than the limit tower many, when a main span adds basic variable load, when another main span does not load, if middle tower rigidity is little, though main push-towing rope cable power difference is less, loading the amount of deflection of striding stiff girder will increase greatly; If middle tower rigidity is big, it is little to load the amount of deflection stride stiff girder, but main push-towing rope cable power difference is bigger, and the uneven horizontal force of generation might cause main push-towing rope in saddle, to slide, thereby makes the stiff girder distortion bigger.In order to improve the rigidity of structure of multitower suspension bridge, the antiskid ability of moving of Tasso tower and strand is very important in the raising.
Summary of the invention
The utility model provides a kind of main rope tower structure of suspension bridge of the not slippage of middle Tasso thigh that is applicable to the large-span multi-pylon cable suspension bridge, adopts this structure, and the antiskid of Tasso tower and strand moves ability in the raising, has improved the rigidity of structure of multitower suspension bridge.

For ease of fixing of strand, in the optimized technical scheme, the cross section of described strand and moulding lining is rectangle, equilateral triangle or regular hexagon.For ease of processing, the number of described moulding lining setting is 1～3, and the quantity of positioning adapter also can be adjusted according to actual needs.
When the strand placed in the saddle groove more than a row; For preventing that strand takes place to slide relatively between adjacent two groups; In the optimized technical scheme; The location-plate of some parallel and equidistant settings can be set in described saddle groove, and the location-plate both sides are respectively equipped with second locating slot that aligns each other, and second locating slot relative with first locating slot aligns each other.The height that location-plate is provided with need confirm that the number that second locating slot is provided with on the location-plate also need be confirmed according to the number of positioning adapter on every strand of reality according to the strand quantity that every row's strand comprises.
The first above-mentioned locating slot and the shape of second locating slot need be confirmed according to the shape of strand and moulding lining, to play better position-limiting action.For ease of the processing of first locating slot and second locating slot, the cross section of generally selecting strand and moulding lining is a rectangle, at this moment, first locating slot and following second locating slot be the cuboid locating slot.
For guaranteeing the whole fastness of strand, three row's strands are set in each saddle groove, this moment, the quantity of described location-plate was two; For further preventing location-plate generation move left and right, be convenient to install, described saddle groove bottom land is provided with stopper slot, two location-plates bottoms respectively with the stopper slot two side near.
The quantity of saddle groove is 2～5 on the described strand fixed head.The quantity of the setting of concrete saddle groove is generally confirmed according to actual needs.
For ease of construction, guarantee the bulk strength of Sarasota simultaneously, described strand fixed head is provided with the saddle groove by the vertical gripper shoe and the notch gripper shoe at vertical gripper shoe top that are fixed on the cable saddle base plate in the notch gripper shoe.According to practice of construction occasion needs, also can select the strand fixed head of other structures for use.
The main rope tower structure of the suspension bridge of the utility model, moving of strand avoided in the employing of locating slot significantly; The antiskid of Tasso tower and strand moves ability in the raising; Improved the rigidity of structure of multitower suspension bridge, be specially adapted to the large-span multi-pylon cable suspension bridge, national economic profit is high.
