Description
Technical Field
The utility model belongs to the technical field of the bridge, specifically speaking especially relates to a shear connector for steel-concrete composite beam.
Background
The steel-concrete composite beam is a new type of beam developed on the basis of steel structure and concrete structure, and usually, the bottom and rib portions of the beam are made of steel beams, the wing plates are made of concrete plates, and the steel beams and the wing plates are connected into a whole by using shear connectors or perforated steel plates. Compared with a structure stressed by a single material, the steel-concrete combined beam bridge has the advantage of high rigidity of a concrete beam, but is lighter than the concrete bridge; the steel is used on the tension side of the structure, so that the defect of poor tension performance of concrete is overcome, and the defect of poor stability of a thin-wall structure is also overcome. Due to the advantages, the combined beam bridge is widely popularized and applied in recent years. The steel-concrete composite beam is mainly connected through a shear connector, the common shear connector is provided with a head stud, the head stud does not need large rolling equipment, field welding is facilitated, and the head stud is widely applied at present, but the head stud also has the problem of weak lifting resistance.
Disclosure of Invention
The utility model aims at providing a shear connector for steel-concrete composite beam to overcome the weak defect of anti ability of lifting that the tape head toggle pin exists as shear connector among the prior art.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a shear connector for steel-concrete composite beam, includes anti-lift auxiliary member and a plurality of interval distribution's bolt group, bolt group is including connecting plate and both sides bolt, the bolt includes bolt pole and bolt head, bolt pole bottom fixed connection first base, the both sides bolt in a bolt group passes through the connecting plate to be connected, anti-lift auxiliary member is including anti-lift pole and a plurality of interval distribution's supporting seat, anti-lift pole setting is at the connecting plate downside and between the both sides bolt in a bolt group, the supporting seat include with anti-support pole fixed connection's bracing piece, bracing piece bottom fixed connection second base.
Furthermore, the two ends of the connecting plate are respectively provided with a C-shaped opening, and the bolt rod is arranged in the opening of the connecting plate.
Furthermore, the middle part of the connecting plate is provided with an arc part protruding upwards.
Further, the stud and the first base are integrally cast.
Further, a plurality of fins are mounted on the bolt rod.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a reform transform present peg commonly used, make anti ability of lifting promote by a wide margin, also can satisfy field weld's needs, reform transform with low costs simultaneously.

In the figure: 1. a stud; 2. a pin rod; 3. bolting the nail head; 4. a first base; 5. a connecting plate; 6. an anti-lifting rod; 7. a support bar; 8. a second base; 9. an opening; 10. an arc-shaped portion.
Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples.
The utility model provides a shear connector for steel-concrete composite beam, includes anti-lift auxiliary member and a plurality of interval distribution's bolt group, bolt group is including connecting plate 5 and both sides bolt 1, bolt 1 is including bolt pole 2 and bolt head 3, 2 bottom fixed connection first bases 4 of bolt pole, and both sides bolt 1 in a bolt group passes through connecting plate 5 to be connected, anti-lift auxiliary member is including anti-lift pole 6 and a plurality of interval distribution's supporting seat, anti-lift pole 6 sets up at connecting plate 5 downside and between the both sides bolt 1 in a bolt group, the supporting seat include with anti-lift pole 6 fixed connection's bracing piece 7, bracing piece 7 bottom fixed connection second base 8.
The utility model can greatly improve the anti-lifting capability of the stud 1 by arranging the anti-lifting auxiliary piece and the connecting plate 5, and the supporting seat further improves the anti-shearing capability; the anti-lifting rod 6 can be made of steel bars, and the support rod 7 and the second base 8 are integrally cast; when the device is installed, the supporting seat and the anti-lifting rod 6 are installed firstly, then the studs 1 on two sides and the connecting plate 5 are installed, and the first base 4 and the second base 8 are fixedly installed on the steel beam through welding.
The two ends of the connecting plate 5 are respectively provided with a C-shaped opening 9, and the bolt rod 2 is arranged in the opening 9 of the connecting plate 5.
The width of the opening 9 on the connecting plate 5 of the utility model is smaller than the diameter of the bolt pin head 3, so that the bolt pin head 3 can not pass through the opening 9 on the connecting plate 5.
The middle part of the connecting plate 5 is provided with an arc part 10 which protrudes upwards.
The stud 1 and the first base 4 are integrally cast.
A plurality of fins are arranged on the bolt rod 2.
The utility model discloses a set up the fin, can further strengthen anti ability of lifting.
The above embodiments are only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
