Four Types of Mechanical Connection
Mechanical connections has four types: Rebar sleeve extrusion connection It is used for on-site connection construction of grade Ⅱ and Ⅲ hot-rolled ribbed steel bars with a diameter of Ф20-32mm in reinforced concrete structures according to the requirements of first and second-level seismic fortification. Rebar taper thread sleeve connection It is used for the connection between steel bars with the same diameter or different diameters of Ф18-50mm grade II, III, and IV ribbed steel bars (including poorly weldable steel bars). Reinforcement upset straight thread sleeve connection It is used for the on-site connection construction of II, III grade vertical, oblique or horizontal steel bars with a steel bar diameter of Ф16-40mm in the concrete structure of industrial and civil buildings. Steel bar rolling straight thread sleeve connection Steel bar rolling straight thread sleeve connection is utilizes the characteristics of plastic deformation of metal materials and cold hardening to...
