Abstract
The invention relates to a fixed connecting structure of a steel tube arch rib and a steel box girder. A steel box girder longitudinal web, a supporting beam and transverse partition boards on two sides are welded with the inside of the steel box girder. Outer side plates of a rectangular structure, an inner partition board of a rectangular structure, a bottom plate of a rectangular structure and a top plate of a rectangular structure are arranged on the positions, corresponding to the longitudinal web and the two transverse partition boards on the two sides of the supporting beam, of top of the steel box girder in a penetration welding mode. The steel tube arch rib extends into the rectangular structure and form a whole with the rectangular structure in a penetration welding mode. The steel tube arch rib and the four walls of the rectangular structure are provided with a first longitudinal connecting plate, a second longitudinal connecting plate, a third longitudinal connecting plate and a transverse partition board in a penetration welding mode. The rectangular structure is arranged on the position, corresponding to the longitudinal web and the transverse partition boards, of the top face of the steel box girder in a penetration welding mode, and the steel tube arch rib extends into the rectangular structure and form the whole with the rectangular structure, so that force of the steel tube arch rib is reliably transmitted to the steel box girder through the rectangular structure. The steel tube arch rib is connected with the steel box girder through the rectangular structure, so that the fixed connecting structure is good in integrity, smooth in force transmission, good in anti-fatigue performance, easy to manufacture in factories, and capable of guaranteeing welding quality.
Description
Technical field
The present invention relates to arched girder junction round steel pipe arch rib and steel case beam consolidation steel tube arch rib and steel case beam consolidation structure in a kind of steel pipe arch bridge.
Background technology
For arch structure, arch springing is arch bridge superstructure load to be delivered to the important Force transmission parts on basis.Aspect stressed, except bearing moment of flexure and axle power, arch springing also will bear bearing and concentrate counter-force.In addition, the steel case beam supporting traverse being connected with arch springing is also bearing larger transverse bending moment and shearing, so the structure design comparison at arch springing place is complicated.At present, there are two kinds of tectonic types Long-Span Tied Arch Bridge arch springing junction.Be a Steel Pipe Concrete Tied-arch Bridge, generally adopt steel pipe type arch rib, girder adopts concrete structure, and arch springing is that steel pipe is connected with concrete structure.Another is rectangle steel arch rib, and girder is steel case beam, and junction, arch springing place is that rectangular configuration is connected with steel case beam.Some little span pedestrian overcrossinges, also have circular empty steel tube arch rib to be connected structure with steel case beam, but arched girder junction is all to adopt that arch rib is stretched into girder inside is fixed.The method adopting is in the perforate of steel case top surface of the beam, arch rib steel pipe is stretched into steel case beam, by vertical lateral partitions and stiffening construction are set, arch rib and steel case beam are connected into integral body, in case, connect structure arch rib and will pass case back plate and case internal partition, stiffening construction is all in case, top board and supporting traverse web all need perforate, and supporting traverse cross section is weakened greatly, support stiffening construction because narrow space is difficult to arrange.In addition, due to narrow space, connect stiffener and be difficult to welding, weldquality is difficult for guaranteeing.
Summary of the invention
The object of the invention is for above-mentioned present situation, aims to provide a kind of levels bridge deck width that can adapt to and differs larger Plate-truss Composite Structure beam, and reasonable stress, construction costs be low, be convenient to manufacture, install and steel tube arch rib and the steel case beam consolidation structure of maintenance.
The implementation of the object of the invention is, steel tube arch rib and steel case beam consolidation structure, vertical web, supporting traverse and both sides diaphragm of weldable steel case beam in steel case beam; At steel case back welding rectangular configuration outer panel, rectangular configuration internal partition, rectangular configuration base plate and rectangular configuration top board;
Steel tube arch rib extend in rectangular configuration, and is welded into integral body with rectangular configuration; Rectangular configuration outer panel, rectangular configuration internal partition are corresponding with the vertical web position of steel case beam, and rectangular configuration base plate is corresponding with diaphragm position, both sides with rectangular configuration top board;
Between steel tube arch rib, rectangular configuration outer panel and internal partition, weld longitudinal junction plate one, longitudinally junction plate one extends to steel case back plate to fulcrum crossbeam place and the welding of steel case back plate; Between steel tube arch rib, rectangular configuration base plate and rectangular configuration top board, weld longitudinal junction plate two, longitudinally junction plate two extends to the vertical web place of steel case beam and the welding of steel case back plate; Between two longitudinal junction plates one, weld longitudinal junction plate three; Longitudinally between junction plate one, two and rectangular configuration base plate, rectangular configuration top board, rectangular configuration outer panel or rectangular configuration internal partition, welding diaphragm.
The present invention, in rectangular configuration of position penetration weld of the corresponding vertical web of steel case top surface of the beam and diaphragm, extend into steel tube arch rib in rectangular configuration, and penetration is welded into integral body, and the power of steel tube arch rib is passed to steel case beam reliably by rectangular configuration.
Adopt tubular arch rib steel of the present invention to be connected with steel case beam by rectangular configuration, good integrity, transmits mechanical compliance smooth, and has good anti-fatigue performance, is easy to factory and manufactures, and guarantees welding quality.
