Description
Technical field
The present invention relates to the pier beam connection type that a kind of steel-mixes composite beam bridge, steel box girder bridge, in particular to a kind of steel-is mixed
Combine pier consolidation structure.
Background technique
Bridge support pattern is mainly single hinge bearing, antitorque double support or multi- supports and pier consolidation at present.Girder with
When using single hinge bearing between pier stud, poor to the antitorque restriction ability of superstructure, Curved Beam Bridge can generate biggish torque,
When being constrained using single support, it is difficult to balance the torque that bridge load generates, causes seat empty or beam body capsizing case.It is antitorque double
Although support or multi- supports are capable of providing good antitorque counter-force, but when there are relatively larger transverse load action, in horizontal force
Effect undersetting still will appear dislocation and failure by shear.Pier consolidation is highly resistant to the torque of bridge superstructure generation,
With excellent overall stability, it is widely used in concrete bridge structure.
In recent years, steel-mixes composite beam bridge, steel box girder bridge, due to its significant Technological Economy comprehensive advantage, in bridge construction
In be continuously available extensive use.However it is a great difficult problem that steel box-girder and performance of concrete column confined, which form pier consolidation, needs to invent
A kind of mixed combination pier consolidation new construction of steel-.
