Abstract
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Claims3
A method for packaging a reinforcement, the method comprising:
- forming a collection of solid wires which are mutually parallel, the solid wires include a central wire and peripheral wires, the peripheral wires being tangential to the central wire and separated from one another, delimiting grooves, a flexible plastic sheath which is extruded onto the bundle, wherein said sheath has a cylindrical exterior shape and has a lobed interior wall with recesses and projections, the peripheral wires being housed in the recesses and the projections extending into the grooves;
- and
- parallel winding the reinforcement onto a drum, making one full twist over one turn.
Method for implementing a reinforcement for a building work, the method comprising:
- forming a collection of solid wires which are mutually parallel, the solid wires include a central wire and peripheral wires, the peripheral wires being tangential to the central wire and separated from one another, delimiting grooves, a flexible plastic sheath which is extruded onto the bundle, wherein said sheath has a cylindrical exterior shape and has a lobed interior wall with recesses and projections, the peripheral wires being housed in the recesses and the projections extending into the grooves;
- and
- in at least one portion of the reinforcement, baring the solid wires and anchoring bared wires to at least a constituent part of the building work so as to cause the reinforcement to work in tension.
