ROD FOR CONCRETE STRUCTURES REINFORCEMENT AND PLANT FOR ITS PRODUCTION Russian patent published in 2005 - IPC

FIELD: building, particularly rods made of mineral fibers to reinforce concrete structures including structures for mounting current conducting components.

SUBSTANCE: rod is formed of mineral fiber roving bonded by hardened polymeric binding agent along the full length thereof. Rod has anchoring catches formed as conical-and-cylindrical bosses. Maximum dimension of boss cross-section is 1.5d - 2d, dimension between catches is 50d - 200d, where d is rod diameter. Plant for rod production includes bobbin carrier on which bobbins with roving are installed, tensioning devices, heating chamber, impregnating bath having wringing means installed at bath outlet, forming unit with extrusion nozzle assembly, transverse winding means, polymerizing chambers, drawing and cutting mechanisms. All above components are connected in single technological line. Drawing and cutting mechanisms are located at the end of technological line. Plant is provided with fixing means which forms anchoring catches located in front of transverse winding means, measuring means arranged in front of cutting mechanism, receiving and packing device installed behind cutting mechanism, remote computer-based control-and-regulating device linked with all above components and mechanisms by tie cables.

EFFECT: increased service performance.
