Problems solved by technology
The stud is a flexible shear connector. Compared with the rigid connector, its bearing capacity is lower, the slip resistance is poor, and it does not have the function of detachment; secondly, the stud connector needs to have a welding link , there will be a lot of wet work during the construction process, so the construction site environment is poor, and the inhalable particulate matter increases, which is harmful to human health
During the use of bolted joints, the preset openings and bolts in the flange of the steel beam often leave holes, and the steel beam and the bolt will have relative misalignment, which will cause problems such as initial slippage and low initial rigidity, and the bolts under the flange of the steel beam Corrosion will occur at the thread of the thread, seriously affecting its mechanical properties

The invention provides an anti-sliding detachable stainless steel stud shear connector which comprises a stud rod, a positioning hole formed in a steel plate corresponding to the stud rod and an anti-corrosion nut, a threaded connector is arranged at one end of the stud rod, penetrates through the positioning hole and extends out, the threaded connector is fixed in the anti-corrosion nut in a screwed mode, a sleeve is connected between the stud rod and the positioning hole, and the anti-corrosion nut is arranged in the sleeve. And the positioning hole is a conical hole. The steel-concrete composite structural material is reasonable in design, has good ductility while meeting the shear bearing capacity, and can be better suitable for high-reinforcement development of the steel-concrete composite structural material; secondly, the conical nut is made of stainless steel, and the stainless steel has excellent ductility and deformation strengthening performance, so that in the screwing process, through plastic deformation of the conical sleeve, on one hand, connection is tight, and on the other hand, the strength of the conical sleeve is higher through corresponding deformation strengthening; and the stainless steel nut is used, so that the corrosion resistance of the material is improved, and the crevice corrosion risk possibly occurring in the later period can be avoided.
Description
technical field [0001] The invention relates to an anti-slip type detachable stainless steel stud anti-shear connector. Background technique [0002] The existing shear connectors of prefabricated composite beams mainly include stud connectors and bolt connectors. The stud is a flexible shear connector. Compared with the rigid connector, its bearing capacity is lower, the slip resistance is poor, and it does not have the function of detachment; secondly, the stud connector needs to have a welding link , There will be a lot of wet work during the construction process, so the construction site environment is poor, and the inhalable particulate matter increases, which is harmful to human health. During the use of bolted joints, the preset openings and bolts in the flange of the steel beam often leave holes, and the steel beam and the bolt will have relative misalignment, which will cause problems such as initial slippage and low initial rigidity, and the bolts under the flange...
