Abstract
The utility model discloses a kind of compound PBL shear connectors suitable for corrugated steel web combination bridge, including the flange plate being welded on corrugated steel web, open pore steel plate is welded among flange plate, reinforcing bar is run through in open pore steel plate hole, and two through weld stud on the corresponding flange plate of reinforcing steel bar center.The utility model not only has stronger shear behavior, and there are also good corrosion resistances.
Description
Technical field
The utility model relates to a kind of compound PBL shear connectors suitable for corrugated steel web combination bridge, for connecting
The corrugated steel web and concrete bridge deck of corrugated steel web composite bridge belong to bridge construction field.
Background technique
Corrugated steel web composite bridge is as a kind of novel steel-concrete combined structure bridge, reasonable stress, beauty
Many advantages, such as economic, makes such bridge have vast potential for future development.
Shear connector is the Force transmission parts for connecting steel-concrete combined structure, and mainly there are two aspects for effect: first is to hold
By the shearing of steel reinforced concrete interface, limits and slid between two kinds of different materials；Second is resistant between two kinds of different materials
Start effect.
The fashioned iron shear connector such as socket cap peg and angle steel, channel steel is most common several in current steel reinforced concrete combined bridge
Connector form, shear resistance is generally and the fatigue problem at root weld is also than more prominent.
PBL shear connector is a kind of novel shear connector, and such shear connector essential characteristic is the vertical welding on steel member
Round-meshed steel plate is connect out, with the frictional force and chemical adhesion of open pore steel plate and concrete and mostly important pin effect
Shearing is resisted, but the lateral shear resistance of PBL shear connector is weaker.Therefore, for corrugated steel web composite bridge, it is necessary to
Existing corrugated steel web PBL shear connector is improved.
Summary of the invention
In order to improve the deficiency of existing corrugated steel web PBL shear connector transverse direction shear resistance, increase its corrosion resistance
Can, the utility model provides a kind of compound PBL shear connector suitable for corrugated steel web combination bridge, and the shear connector is not only
With stronger lateral shear behavior, there are also good corrosion resistances.
The utility model is completed by following technical proposal: a kind of suitable for the compound of corrugated steel web combination bridge
PBL shear connector welds open pore steel plate including the flange plate being welded on corrugated steel web among flange plate, in open pore steel plate hole
Through reinforcing bar, and two through weld stud on the corresponding flange plate of reinforcing steel bar center.
Perforative reinforcing bar is basalt fiber tendons in the open pore steel plate hole.
The utility model has the advantage that the isotropism that peg shearing resistance is utilized on the basis of PBL shear connector shearing resistance
Ability enhances its lateral shear resistance, and perforative basalt muscle can reinforce the shearing resistance effect of open pore steel plate inner concrete, simultaneously
Shear connector is avoided to reduce shear resistance because of corrosion.

Fig. 1 is the perspective view of the utility model.
Fig. 2 is the side view of the utility model.
Fig. 3 is the top view of the utility model.
Fig. 4 is the front view of the utility model.
Wherein, 1, steel plate hole, 2, flange plate, 3, corrugated steel web, 4, peg, 5, basalt fiber tendons, 6, open pore steel plate.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawing.
A kind of compound PBL shear connector suitable for corrugated steel web combination bridge as shown in Figure 1,2,3, 4, first by the wing
Listrium 2 is welded on corrugated steel web 3, then open pore steel plate 6 is welded on to the center of flange plate, then in open pore steel plate 6
Steel plate hole 1 go out weld basalt fiber tendons 5, finally in the middle position weld stud 4 of two basalt fiber tendons 5 in the edge of a wing
On plate 2.
As described above, the utility model can be realized.
Claims (2)
1. a kind of compound PBL shear connector suitable for corrugated steel web combination bridge, it is characterised in that: on corrugated steel web
