Abstract
The invention relates to a main girder of a steel box composite girder with long cantilever arms for a single-plane cable stayed bridge. The two sides of a steel box girder in the middle of the main girder are respectively provided with a steel cantilever arm, and the steel box girder and the steel cantilever arms are connected by high strength bolts in bolting and welding modes; and the end part of each steel cantilever arm is provided with a longitudinal side beam, the tops of the steel box girder and the steel cantilever arms are paved with concrete bridge decks or cast-in-situ bridge decks, traffic lanes are arranged on the steel cantilever arms, the steel box girder is in a single-box single-chamber structure or multi-chamber structure, and a steel anchor box is arranged at the anchor point of a stayed cable. By adopting the steel box composite girder with long cantilever arms, the stress problems of the main girder, such as the torsion resistance and the like of the single-plane cable stayed bridge, are solved, and the horizontal dimension of the main girder is reduced; the main girder can be transported to the bridge location to carry out erection and installation, thereby solving the problem that the sectional dimension of the appearance is limited; and because most of the components of the main girder are prefabricated ones, the in-situ workload is reduced, and the construction quality and construction period can be effectively guaranteed. The main girder provided by the invention is specially adapted to the construction conditions in severe cold districts, for example, the main girder is applied to the construction of the Wusu Bridge in HeiXiazi Island of Heilongjiang Province, and achieves a good application effect.
Description
Technical field
Patent of the present invention relates to the steel case bondbeam girder that a kind of band that is used for single plane cable stayed bridge is chosen arm greatly.
Background technology
Cable-stayed bridge main-beam generally adopts forms such as girder steel, concrete beam, steel reinforced concrete bondbeam.
The span ability of girder steel is big, and speed of application is fast, reliable in quality degree height, but steel girder price is more expensive, and the paving steel bridge deck of orthotropic plate is a global problem simultaneously, does not also have good solution at present, durability is difficult to obtain assurance, and later maintenance maintenance work amount is big.Especially at extremely frigid zones, winter snow cover needs to remove with modes such as spilling Snow Agent, adopts the steel girder comparatively unfavorable for the anticorrosion maintenance of the later stage of bridge deck; And because steel work transportation in bridge location place can only be adopted the land route transportation, limited the size of transport member, adopted steel girder building-site welding job amount bigger.
The rigidity of concrete girder is big, and the mobile load amount of deflection is little, and train operation performance is good, and wind resisting stability is good, and cost is low.But span ability and speed of application are all not as steel work.At extremely frigid zones, the annual effectively construction period is 5 months, if adopt concrete girder time of setting up of then constructing longer, is unfavorable for mobilization.
The steel reinforced concrete bondbeam is to replace Orthotropic Steel Bridge Deck commonly used with precast concrete plank on the steel girder, and it can also be saved rolled steel dosage and rigidity thereof and wind resisting stability and all be better than the steel girder except that having the pluses and minuses identical with the steel girder.Its bridge floor rigidity is bigger, and train operation performance is better, and the long service life on road surface is convenient to maintenance.
Adopt the bondbeam scheme then to bring into play the advantage of steel girder and concrete girder and avoided their shortcomings separately, but traditional single rope face bondbeam girder steel partial cross section is bigger, be not easy to the land route transportation, if be transported to the scene after the transversal sectional manufacturing, then the field Welding workload is too big.
Usu, black bear island, Heilongjiang Province bridge is positioned at Fuyuan delta, Heilongjiang Province (claiming the black bear island again), is located in the eastern utmost point of China, is described as " east first bridge ".Because bridge location is in extremely frigid zones, geographical position and environment are all very special, have inconvenient traffic.
Adopt traditional steel reinforced concrete bondbeam cross section can not satisfy the structure manufacturing, transport and set up needs.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide and a kind ofly can effectively solve the antitorque problem of single plane cable stayed bridge girder, the exterior cross-section size is unrestricted, and the band that the duration is short, reliable quality is used for single plane cable stayed bridge is chosen the steel case bondbeam girder of arm greatly.
The implementation of the object of the invention is, the band that is used for single plane cable stayed bridge is chosen the steel case bondbeam girder of arm greatly, and the steel case beam both sides in the middle of the girder are that steel is chosen arm, and steel case beam is chosen arm with steel and is connected by high-strength bolt bolt or welding manner; It is the limit longeron that steel is chosen the arm end, and steel case beam and steel are chosen the arm top and laid concrete slab or cast-in-place bridge deck, and runway is positioned at steel to be chosen on the arm, and steel case beam is single box single chamber or multicell structure, at the suspension cable anchor point steel anchor box is set.
The present invention chooses the girder form of this half assembly unit of steel case bondbeam of arm by use with big steel, has both solved the antitorque stressed problem that waits girder of single plane cable stayed bridge, has reduced the lateral dimension of girder again; Girder communications and transportation over land sets up installation to bridge location, has solved the problem that the exterior cross-section size is restricted; Because the girder major part is prefabricated units, has reduced the field operation amount, the duration of setting up that the construction quality of structure reaches also can be effectively guaranteed; The problem of having avoided the paving steel bridge deck durability.The present invention adapts to the execution conditions of extremely frigid zones especially, as adopting at Usu, black bear island, Heilongjiang Province bridge, has obtained good utilization effect.
