Designed specifically to coil standard coiled rebar into continuous circular spiral reinforcement. These spirals are primarily used in conjunction with prestressing anchorages; they are placed outside the bearing plate and embedded in the concrete to disperse localized stress at the tensioning end and prevent cracking beneath the anchor. It is specialized processing equipment for prestressing applications in bridge and building construction.
Horizontal Forming Drum: A rotating main spindle drum around which the rebar is wound to form uniform spiral coils; drums of various diameters can be interchanged to produce spirals of different specifications.
Rebar Guiding & Feeding Screw: A long spiral mechanism located at the bottom that feeds the rebar at a constant speed and controls the coil spacing (pitch).
Reduction Gearbox & Drive Motor: A motor located in the lower frame drives the drum and feeding mechanism synchronously via a gearbox, ensuring a consistent coiling rhythm.
Integrated Frame: A steel base structure ensuring stable operation and suitability for on-site processing layouts.
The produced spirals directly meet the requirements for various circular and flat anchorages, replacing manual bending. They feature uniform inner diameters, coil spacing, and coil counts, ensuring consistent stress dispersion beneath the anchor.
Interchangeable main spindle drums allow for the production of spirals compatible with anchorages ranging from 4 to 19 strands.
Precise control of spiral spacing is achieved by adjusting the feeding screw speed, ensuring high consistency across batches.
The number of coils can be preset; the finished product is obtained by manually cutting the rebar after forming.
Compared to manual bending and spot welding, mechanized continuous coiling offers high speeds. It is ideal for the centralized, high-volume production of spirals for bridge anchorages, significantly reducing labor costs.
Transmission components are standardized, and parts such as drums and guides can be replaced individually. Routine maintenance requires only bearing lubrication, and the machine maintains a low failure rate even in harsh construction site environments. IV. Main Applications
Fabrication of matching spiral reinforcements for use beneath multi-hole circular anchors and flat anchorages;
Processing of reinforcement at the anchorage ends of bridge T-beams, box girders, and prestressed basement floor slabs;
Prefabrication of spiral stirrups for the anchorage ends of foundation pit anchor cables.
