12mm-40mm Metal Building Material Rebar Couplers Connector
product description:
The straight thread connection of steel bars is to peel off part of
the longitudinal ribs and transverse ribs at the ends of the steel
bars to be connected by cutting with a thread rolling machine, and
then directly roll them into ordinary straight threads, which are
connected with special straight thread sleeves to form steel bars'
Connection.
The technology is efficient, convenient and fast construction
method, energy saving, consumption reduction, improvement and
connection quality are stable and reliable.
Rebar straight thread connection technology
1. Rib stripping and rolling process
(1) The end of the steel bar is cut flat;
(2) The professional rib stripping and thread rolling machine strips and rolls the end of the rib; (3) Use the connecting sleeve to connect the steel bar.
2. Features
(1) The joint has high strength, which can exert the tensile and compressive strength of steel bars, and meet the Chinese standard (JGJ107), American standard (UBC1997), British standard (BS8110), French standard (NF35-20-1), German standard (NF35-20-1), German standard Standard (DIN1045), ISO/WD15835 (draft) and other relevant domestic and foreign standards requirements;
(2) simple operation, no need for professional technicians, fast on-site connection;
(3) high production efficiency, prefabricated in advance, not occupying the construction period;
(4) ) Economical, equipment, low cost;
(5) Environmental protection, safety, not affected by the environment and climate.
