Further, reinforcing bar employed in the steel mesh is plain bar, spiral or fiber reinforced plastic rod.
The beneficial effects of the utility model are:
1, using the shear connector of the utility model, shearing strength and the shearing resistance for further improving shear connector are rigid
Degree, so that the combined efficiency between wood and concrete is improved, while shear connector category provided by the utility model
In partially rigid connector, there is good anti-fatigue performance.
2, the utility model reduces the shear-deformable of connector, and then subtract relative to traditional flexible shear connector
Lack wood-concrete combination beam overall deformation, is improved a combination thereof efficiency, structural behaviour is more superior.In addition, this reality
Belong to partially rigid shear connector with the shear connector that Novel photo provides, it, can be effective while resisting Relative sliding
Inhibit to start effect between concrete slab and wooden frame, so that the two can be good at cooperating.
3, the utility model provides a kind of new approaches of stud connector design, has expanded the application range of composite structure, tool
There are good social benefit and conversion prospect.
