The reason for using positive and negative wires for the connection of steel bar sleeves is to prevent the heads connected at other places from being loosened or falling off. The rebar sleeve is used in the position where the rebar cannot be rotated, and it can be connected with a left and right threaded connecting sleeve. It requires that one end of the connecting sleeve and the steel wire head on the corresponding side be processed into a left-handed thread. Close in the middle and screw into the top, so as to realize convenient and quick connection.
Rebar connection technology is quite successful in some senses, and has its own characteristics, so as to adapt to the continuously developing industry and social trends. The lap connection method can no longer be used for the connection of large-scale steel bars, and welding has many shortcomings, (such as unstable steel material, poor weldability, etc.; unstable power supply or poor welder level; construction period tightness, insufficient capacitance; and weather effects such as wind, rain and cold; and construction plans for places with high fire protection requirements; the quality and speed of on-site connection of horizontal steel bars.) Welding quality cannot be guaranteed.
