Abstract
The present invention relates to a machine and to a method for producing uniaxial reinforcing steel bar meshes, in particular for uses with not predominantly static load, wherein reinforcing wires are fastened to support strips by means of individual wire tying.
Claims12
A machine for producing uniaxial reinforcing steel bar meshes, having a steel strip conveyor (1) for conveying a plurality of support strips (2) which are parallel to one another and spaced apart from one another, and a reinforcing bar conveyor (3), wherein the reinforcing bar conveyor (3) conveys individual reinforcing bars (4) in a crossing manner onto the plurality of support strips (2), forming crossing points (5), and also positions them in a longitudinal-axial manner with respect thereto, and a plurality of connecting units (6) operatively arranged at each crossing point (5), wherein a connecting unit (6) has a binding wire conveyer (7) feeding a binding wire (8) through a rotating unit (9), wherein the rotating unit (9) is movable relative to the support strip (2) and the crossing reinforcing bar (4) and is arranged on a side of the plane defined by the support strip (2) and the reinforcing bar (4), wherein the connecting unit (6) further has a binding wire guide unit (10) which is arranged on the opposite side of the plane and which frictionally feeds out and holds a binding wire (8) fed thereinto by the binding wire conveyer (7) in a direction reverse to the infeed direction, wherein the rotating unit (9) twists the two binding wire strands (11) located on a side of the plane together and cuts them to length, characterized in that the rotating unit (9) and the binding wire guide unit (10) are moved towards each other in a closing manner to form a wire loop connecting the support strip (2) and the reinforcing bar (4) in such a manner that the support strip (2) and the reinforcing bar (4) are pressed against each other.
A method for producing a uniaxial reinforcing bar mesh from a plurality of reinforcing bars which are parallel to each other and spaced apart from each other and are orthogonally oriented to and fastened to a plurality of support strips which are parallel to each other and spaced apart from each other, comprising the following steps:
- a) feeding a reinforcing bar orthogonally to the longitudinal axes of parallel support strips which are spaced apart from each other to create a plurality of crossing points between the respective steel strip and reinforcing bar,
- b) pressing the reinforcing bar onto the support strip to hold it in close position,
- c) feeding a binding wire in the region of a crossing point around the steel strip and the reinforcing bar thereby forming a double binding wire strand on one side,
- d) cutting the binding wire to length and twisting the two binding wire strands thus created to form a twisting section.
