Technical field
The utility model relates to a kind of hinge seam structure of concrete plate beam.
Background technology
In Chinese Highway bridge construction, most of middle-size and small-size structure adopts assembling articulated slab girder construction, its principle is: between each plate-girder is horizontal, by cast-in-place tongue and groove concrete pin and welded reinforcement, connect, whereby each plate-girder is laterally linked to be to integral body, increase the active area of load, making to act on Local Loads on carriageway plate distributes to each plate-girder and jointly bears, the load that makes each piece plate-girder bear is tending towards evenly, thereby avoids the excessive situation that even occurs that veneer is stressed of the stressed difference of each single plate-girder.Simultaneously, the size of the Transverse Distribution of load is determined by hinge seam and the coupling stiffness of plate-girder, the quality of bridge integrity also depends on the size of hinge seam and plate-girder coupling stiffness, and therefore, hinge seam plays an important role to the workability of whole bridge and durability.
Yet under actual conditions, owing to being subject to the impact of the factors such as design, construction, the actual operation situation of bridge, the force-mechanism complexity of hinge seam is various, destruction multi-form, in various degree very easily occurs, thereby lose its due effect.Once hinge seam is destroyed, its Shear transfer deleterious, when wheel acts on a certain plate-girder, all wheel load will be born separately by this plate-girder, formed disadvantageous " veneer is stressed " state, when particularly loaded vehicle passes through repeatedly, the changing of the relative positions repeatedly up and down of hinge seam both sides plate-girder, the destruction of more having increased the weight of hinge seam.So just, affect the stressed of whole bridge, shortened the service life of bridge.
