Cold extrusion bar splicing is a new form of mechanical connection, the basic principle is: Insert two un-connected bars into a special connecting sleeve, then use hydraulic tool press sleeve in radial direction, make sleeve occur plastic deformation, thus make sleeve's inner wall embed the grooves of rebar's cross rib, finally implement the connection of two bars. Axial force that the rebar bears is mainly through rebar's rib and the shear force between sleeve after deformation to pass.

Main Features:

 It belongs to Grade 2 connection

(1)The tensile strength of rebar splicing is very strong, it can meet requirement of standard at home and abroad such as: China Standard(JGJ107), America Standard(UBC1997), British Standard(BSB110), French Standard(NF25-20-1), German Standard(DIN1045), ISO/WD15835(draft);

(2)Handy operation, no need skilled operator;

(3)Small need of impetus, no affected by the electric power supply in the site;

(4)Environmental protection, no need operation with open flames, no affected by the weather.
