Tall steel columns with studs what effect is there?
In China, most of the high-rise building load-bearing structure use of steel column, steel encased concrete in the outer layer, the stud used in steel columns of concrete layer surface is used to connect the column surface, to increase the connection area, increase the contact surface shear strength, the steel column and the concrete surface, firmly combined stress common.
The fastener stiffness of stud belongs to a kind of connection of high strength, used in all kinds of steel structure engineering, in different joints in rigid composite connection. The stud is cheese head studs for arc stud welding (Cheese head studs for arc stud English welding) abbreviation, the studs specifications for the nominal diameter of 10 mm to 25mm, the total length of 40 ~ 300mm before welding.
Methods: through stud welding welding robot power, column set in stud welding gun, anti arc seat, starting gun, current fuse, ring is generated by arc, short columnar stud with a certain speed the top tight end of base metal melting, cut off the power supply of columnar stud welding fixed to the base metal. This method is also called stud welding.
