Part, the floorings are equipped with cast-in-place hole corresponding with shearing-resistant member arrangement position, are poured ultra-high performance concrete in cast-in-place hole.
Further, the shearing-resistant member includes peg and steel plate, and the peg is symmetrically fixed on the two sides of steel plate, institute
The steel plate stated vertically connects girder.
Further, the peg is shank of bolt, which, which wears, is welded on steel plate.
Further, the peg is arranged in parallel on the steel plate or is staggered.
Further, the shearing-resistant member along girder along bridge to middle line be alternatively arranged.
Further, the shearing-resistant member along girder along bridge to middle line continuous arrangement.
Further, the shearing-resistant member is connected with girder by welding manner.
Further, the girder is i-shape steel beam or steel beam with box shape.
Compared with prior art, the utility model has the advantage that
1, the utility model is coupled by the cast-in-place hole on shearing-resistant member and floorings, and passes through very-high performance coagulation
Soil carries out casting fixation, and simple structure and reasonable design, construction is convenient, can significantly improve welding quality and shear behavior.
2, the shearing-resistant member of the utility model includes peg and steel plate, and steel plate is vertically connected on girder, and the two sides of steel plate is set
There is symmetrical peg, after ultra-high performance concrete pours, the active force of bridge panel is first transmitted to peg and carries out certain subtract
It is slow, then steel plate is transmitted to by peg, it is applied on girder finally by steel plate, largely reduces and act directly on steel plate and master
The residual stress of beam weld makes main beam stress performance more preferably, improves shear behavior, keeps connection structure safer reliable.
3, the cast-in-place hole on the utility model floorings customizes in advance in factory, and shearing-resistant member carries out prefabricated in factory and girder
Welding, thus welding quality improves, and factory's welding is better than site welding, and then floorings exist with the girder for being connected with shearing-resistant member
Construction site carries out assembly, greatly improves construction efficiency, shortens the construction period.
4, in the utility model, floorings carry out live dress by ultra-high performance concrete with the girder for being welded with shearing-resistant member
With splicing, ultra-high performance concrete, which pours, can accordingly reduce anchorage length, and shrinkage and creep is smaller, meanwhile, with superelevation
Energy concrete cast in situs is conducive to the shear behavior of girder Yu the common stress of floorings.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
As shown in Figure 1 to 4, a kind of shear connections structure for bridge, including more girders 3 are present embodiments provided
With floorings 4.The girder 3 is steel construction girder, and more girders 3 are arranged in parallel on bridge pier, and section form can be I-shaped,
Box etc., uses steel I-beam in the present embodiment, floorings 4 are mounted on girder 3.It is respectively provided on the top surface of every girder 3 more
A shearing-resistant member, floorings 4 are equipped with cast-in-place hole 5 corresponding with shearing-resistant member arrangement position.Floorings 4 use reinforced concrete structure,
Transverse structure reinforcing bar in floorings 4 clean cut system at cast-in-place hole 5 is pre-buried, the longitudinal structure reinforcing bar in floorings 4 along bridge to
Arrangement.When assembled in situ, cast-in-place ultra-high performance concrete completes the connection of girder 3 and floorings 4 at cast-in-place hole 5.
