Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to a kind of compound beam perforate steel plate shear connector device.
Background technology
At present, many countries have studied multiple shear connector device and have used in the combining structure beam, but different shear connectors all can have certain influence to the economy and the durability of bridge or building structure.
Existing shear connector all is to adopt traditional weldering nail formula shear connector or round hole formula shear connector basically, and traditional weldering nail formula shear connector is being striden in the girder construction greatly or used less in the composite beam bridge owing to the restriction of shear-carrying capacity.Round hole formula steel plate shear connector begins to be subjected to extensive attention striding greatly in the composite beam bridge, but because its open-cellular form be circular, can allow rotation, so its supporting capacity is had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, composite beam bridge perforate steel plate shear connector device that supporting capacity is strong.
The composite beam bridge perforate steel plate shear connector device that the utility model proposes, constitute by concrete 1, steel work 2, shear connector 3, transverse reinforcement 4, wherein, shear connector 3 is column construction, have tri-angle-holed 5 in it, shear connector 3 is fixed in steel work 2 one sides, any drift angle of tri-angle-holed 5 in the shear connector 3 is facing to steel work 2, or the triangle in the shear connector 3 is parallel with steel work 2 on one side arbitrarily, shear connector 3 is built in concrete structure 1, concrete 1 is connected with steel work 2, and transverse reinforcement 4 passes tri-angle-holed 5.
In the utility model, the number of tri-angle-holed 5 in the shear connector 3 be 1 to a plurality of, look the length decision of shear connector 3.
In the utility model, the arrangement mode of tri-angle-holed 5 in the shear connector 3 is: arrange facing to the order of steel work 2 according to any drift angle.
In the utility model, the arrangement mode of tri-angle-holed 5 in the shear connector 3 is: arrange according to the order that triangle is parallel with steel work 2 on one side arbitrarily.
In the utility model, the arrangement mode of tri-angle-holed 5 in the shear connector 3 is: alternately arrange facing to parallel with the steel work 2 on one side arbitrarily mode of steel work 2, triangle according to any drift angle.Limit the rotation of reinforcing bar, improved the structure shear-carrying capacity greatly.
This device is become by the steel rib of steel, concrete, reinforcing bar, two kinds of materials of connection and the perforate bonding force key combination on the steel rib, and the form of bonding force key is the triangle perforate.Mechanism's concatenation ability of this form is strong, shear resistance height, thereby the efficient of performance shear connector.
The beneficial effects of the utility model are:
1, improves the shear resistance of combining structure
Adopt the utility model, can improve the shear resistance of combining structure, give full play to the efficient of combining structure.The triangle perforate steel plate shear connector that the utility model proposes, in the numerical experiments process, bear 383.901kN external force after, malformation only is 0.726811mm.And traditional circular shear connector is after bearing 383.2836kN external force, and malformation is 1.56396mm.Therefore the utility model can improve the shear resistance of combining structure.
2, strengthen the binding ability of combining structure
Compare common shear connector, the utility model can make steel and concrete material more effectively combine, thereby has improved the binding ability of two kinds of materials.
3, the steel rib use amount that combines with concrete of minimizing
Because the utility model than traditional shear connector efficient height, therefore, is compared traditional circular shear connector, can use combination steel rib still less, and reach same effect, reduce construction costs.
