Abstract
The utility model discloses a tower-top saddle slot structure for a single-cable cable-stayed bridge and relates to a structure connecting the stay cable with the kingtower of a single-cable cable-stayed bridge. For the tower-top saddle slot structure of a single-cable cable-stayed bridge, a cast steel saddle slot 2 is fixed on a concrete base 1, an inner saddle steel pipe 4 is arranged inside the cast steel saddle slot 2, a saddle covering plate 3 is arranged above the cast steel saddle slot and a positioning steel plate 5 is arranged below the cast steel saddle slot. The tower-top saddle slot structure for a single-cable cable-stayed bridge is installed on the head of the concrete base 1 of the kingtower, wherein, an anchor-block steel pipe 10 is respectively anchored on both sides of the head of the concrete base 1; the stay cable 8 of the single-cable cable-stayed bridge is arranged penetrating the anchor-block steel pipe 10 and the inner saddle steel pipe 4; ethoxyline mortar 6 is concreted around the stay cable 8 outside the inner saddle steel pipe; a damping device 9 is anchored, and finally a parrel 7 is additionally arranged outside the damping device 9. The tower-top saddle slot structure for a single-cable cable-stayed bridge has simple construction, small lifting weight, uncomplicated manufacturing technique, strong applicability for the anchoring structural form of the tower-top stay cable, simple and sprightly appearance, convenient maintenance with fast and convenient maintenance structure, and simple and convenient assembly as well as disassembly.
Description
Technical field
The utility model 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 purpose of this utility model 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 utility model purpose 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 utility model 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 utility model 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.
