Abstract
The invention discloses a saddle groove structure at the top of a tower for a single-cable cable-stayed bridge, in particular to a structure that the stayed cable is connected with main tower of the single-cable cable-stayed bridge, which is characterized in that: a casting steel saddle groove 2 is fixed on a concrete base 1 and is provided with an inner steel tube 4 for the saddle base with a cover plate 3 for the saddle base at the upper part and a positioning steel plate 5 at the lower part. The structure is arranged at the end of the concrete base 1 of main tower; wherein, firstly a steel tube 10 for an anchor block is anchored at both sides of the end; a stayed cable 8 of the single-cable cable-stayed bridge is penetrated through the steel tube 10 for the anchor block and the inner steel tube 4 for the saddle base; epoxy resin mortar 6 is poured around the stayed cable 8 outside the steel tube in the saddle base; a damping device 9 is anchored and is provided with a hoop 7. The invention has the advantages of simple and easy construction, small lifting, strong applicability for the anchoring structural style of the, good shape, brevity and lucidity, convenient maintenance, convenient maintenance structure and convenient assemble and disassemble.
Description
Technical field
The present invention relates to the structure that a kind of suspension cable of single cable stayed-cable bridge is connected with king-tower.
Background technology
Recent two decades comes, Bridges in Our Country technology, constructional materials develop rapidly, and cable stayed bridge is light and handy, attractive in appearance, economical, suitable with it, has obtained extensive use in the highway in China bridge construction, and its span ability continues to increase.
The suspension cable of single cable stayed-cable bridge plays critical role in cable stayed bridge, its end connects girder, and an end connects main tower, gives king-tower the huge weight transfer that the beam body bears, alleviate the suffered load of girder, form the primary structure of slant-pull structure as sinking support with it.The anchor type that suspension cable and king-tower generally adopt has multiple, suspension cable for single cable stayed-cable bridge is worth research in the anchor structure form of cat head, be anchored at cat head if adopt common form of structure to intersect, king-tower structure construction size certainly will will be strengthened greatly, if adopt the Tasso connection mode of part cable stayed bridge from moulding and on stressed, then to be difficult to satisfy related request, therefore need provide new suspension cable, king-tower anchor connection mode.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of profile brevity and lucidity/manufacturing, install uncomplicated, maintainable good, reliability is high, the saddle groove structure of single cable stayed-cable bridge tower top of good economy performance.
The implementation of the object of the invention is, saddle groove structure of single cable stayed-cable bridge tower top, cast steel saddle groove 2 is fixed on the concrete bed 1, and steel pipe 4 in the saddle is arranged in the cast steel saddle groove 2, on saddle cover plate 3 is arranged, fixing steel plate 5 is arranged down.
The present invention is positioned on the termination of the concrete bed 1 of king-tower, elder generation is at the both sides anchoring anchor block steel pipe 10 of concrete bed 1 termination, the suspension cable 8 of single cable stayed-cable bridge pierces in anchor block steel pipe 10 and the interior steel pipe 4 of saddle, the outer suspension cable 8 circumfusion epoxy resin mortars 6 of steel pipe in the saddle, and anchoring damping device 9, damping device 9 adds parrel 7.
The present invention has following advantage:
1, easy construction, lift heavy is little, and manufacturing process is uncomplicated;
2, applicability is strong, has very strong applicability for cat head suspension cable anchor structure form;
3, profile is good, brevity and lucidity;
4, easy to maintenance, have and safeguard structure very easily, dismounting is easy.

The specific embodiment
With reference to Fig. 1,2, the present invention is made up of cast steel saddle groove 12 and locking device 11.With reference to Fig. 2,3a, b, cast steel saddle groove 2 is fixed on the concrete bed 1, and steel pipe 4 in the saddle is arranged in the cast steel saddle groove 2, on saddle cover plate 3 is arranged, fixing steel plate 5 is arranged down.
With reference to Fig. 4,5, the present invention is positioned on the termination of the concrete bed 1 of king-tower, elder generation is at the both sides anchoring anchor block steel pipe 10 of concrete bed 1 termination, the suspension cable 8 of single cable stayed-cable bridge pierces in anchor block steel pipe 10 and the interior steel pipe 4 of saddle, the outer suspension cable 8 circumfusion epoxy resin mortars 6 of steel pipe in the saddle, and anchoring damping device 9, damping device 9 adds parrel 7.
The present invention adopts cat head saddle groove structure to avoid all construction problems that the general anchor structure form of suspension cable cat head is brought cleverly, the structure brevity and lucidity, the convenient installation and maintenance, have the dual function of suspension cable locker on suspension bridge cat head saddle groove, the part Tower Column of A Cable Stayed Bridge concurrently, not only economy but also suspension cable is reasonably solved in the anchoring problem of cat head.Suspension cable turns to by cast steel saddle groove, and locked device and cast steel saddle groove be fixed together, and safety is good, reliability is high.
