ABP Scaffolding
Steel bar ribbed and straight thread connection technology is a new technology of reinforcing bar connection. Its structure principle is to strip off part of the longitudinal and transverse ribs connecting the end of steel bar, and then directly roll into the normal straight thread and connect with the special straight thread sleeve to form the connection of the steel bar. There is no false thread, good mechanical properties, safe and reliable connection, and superior strength. The joint performance meets the indexes of the first grade joint.
Suitable for all kinds of reinforced concrete structures under tension and pressure bidirectional force.
Material saving, energy saving, with no restriction on steel composition and type.
Operation is convenient and fast, significantly shortening the construction period.
