Description
Technical field
The present invention relates to bridge construction technical field, especially relate to a kind of steel case Combined concrete trough girder bridge construction.
Background technology
At present, along with the develop rapidly of China's communications and transportation, in Practical Project, highway and Urban Bridge and railway arrange clover leaf situation and get more and more, road network interweaves, bridge often need to go up simultaneously across with Xia Chuanduotiao highway and railway, on bridge, under-clearance requires harsh, bridge can be very little by building height, steel tank type girder construction bridge deck building height is little, significantly reduce grade elevation, reduce bridge approach, and structure section space availability ratio is high, also have sound barrier effect concurrently, sound insulation and noise reduction is effective, and vehicle can be stoped to topple whereabouts, ensure that the operation security of crossed line well, there is good economic benefit and urban effect.Existing steel tank type girder construction, the restriction of the own characteristics such as, welding residual stress large, fatiguability many by the structure such as the easy unstability of steel work, stiffening rib diaphragm, exists a lot of difficult in actual applications.
Summary of the invention
The present invention provides a kind of steel case concrete grooved beam bridge for solving in known technology the technical problem that exists, this bridge not easily unstability, weld seam is few, welding residual stress is little, can effectively improve structural bearing capacity, rigidity, anti-fatigue performance.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
The advantage that the present invention has and good effect are:
1) compared with conventional steel grooved beam bridge, girder adopts steel case concrete structure, make full use of the compressive property that concrete is good, assist steel case stressed, reduce steel case stress level, prevent tank wall steel plate local buckling, Reducing distortion, drastically increase the bending resistance of component, torsional rigidity, supporting capacity and ductility are significantly improved.
2) compared with traditional steel tank type beam bridge, girder adopts steel case concrete structure, steel grade can reduce, and scantling and deck-molding can significantly reduce, and stiffening rib and diaphragm can less with even not using, weld seam quantity falls sharply, welding residual stress significantly reduces, and effectively prevent the fatigue failure caused thus, and cross-sectional configuration is tending towards simple, specification reduces, adapted to modern industry efficient, fast, batch production, standardization, segmentation requirement.
3) compared with traditional steel tank type beam bridge, steel case concrete structure is adopted in the region that the shearings such as bearing, Concentrated load place are larger, except concrete itself can participate in cross section bending resistance, shearing resistance and partial pressing, also substantially increase the local stability of steel case web and frange plate, and facilitate follow-up bearing jacking, for construction and later stage replacing time provide good platform.
4) compared with traditional steel tank type beam bridge, in bridge deck and steel case web junction, improve rigidity and the bearing capacity of node build concrete in steel case after, reduce the stress concentration degree of Nodes, improve the anti-fatigue performance of structure.
5) compared with traditional steel tank type beam bridge, after girder adopts steel case concrete structure, anticorrosion area falls sharply, and saves anticorrosion expense, also makes fire resistance simultaneously, crashworthiness is improved.
In sum, the present invention is by adopting steel case concrete structure girder, except there is the advantage of conventional steel grooved beam bridge, steel and concrete material feature are separately given full play to, there is stress system reasonable, the features such as supporting capacity is high, rigidity is large, anti-fatigue performance is good, improve traditional structure in construction and the safety of operational phase, reliability, durability and the ability to ward off risks.And the present invention is simple and reasonable for structure, make easy construction, structural mechanical property is superior, has a good application prospect.
