Cold-extruded connections of rebar connector is to insert the rebar into the extruding sleeve and use crushing clamp to squeeze the sleeve to produce plastic deformation and compact tightly with the surface of the concrete iron to form a joint. Comparing with the welding technology, the joint quality is stable and reliable. It has the advantages of no environmental impact, all-weather construction, joint seismic resistance, fatigue durability and low-temperature resistance. The rebar connector is used with high pressure pump station, high pressure oil pipe, crushing clamp, moulding-die and so on.
It is compacted tightly, easy to use, light in weight, easy to move, simple to operate, adjustable in press clamp speed, and used flexibly in various complex environments.
Cold-extruded connection of steel sleeve is a new technology for reinforced concrete structure construction. It is mainly used in hydropower construction, building engineering, high-rise frame, railway, flood control dam, airport construction, tunnel, earthquake-resistant buildings, marine embankment slope and other rebar connection applications.
Common faults and Exclusion methods
Abnormal phenomena and defects
Extruding machine without extrusion pressure
1. The connection position of high pressure oil pipe is incorrect and should be corrected. 2,oil pump fault, should be checked and removed.
Uneven indentation distribution
When pressed, press with the mark drawn on the sleeve.
1. straighten the rebar when crimped 2. cut or straightening the end of a rebar with a bend
Un-enough pressing level
1. Check if the pump and pipeline are leaking and the pump pressure is not enough.2. Check if the sleeve material can meet the requirement.
Un- enough length of the
rebar inside the sleeve
Mark the rebar accurately and align with the end of the sleeve
Obviously uneven indentation depth
1. check whether the sleeve material meets the requirements 2. check whether the rebar in the sleeve is of empty pressure.(the length of the rebar is not enough)
