Patent ID: 8595912

Claim:
Method for reinforcing a construction work using reinforcing bands, said method comprising, for each of the reinforcing bands: a) anchoring a first zone of the reinforcing band onto the construction work and establishing a free portion of the reinforcing band; b) tensioning the reinforcing band by applying traction to a second zone of the reinforcing band located in the free portion, said traction causing an elongation of and a reactive force in the reinforcing band, the free portion of the reinforcing band being free to slide on the construction work as it elongates; and c) mechanically attaching the reinforcing band to the construction work, so as to absorb the reactive force from the reinforcing band in an area of the construction work which can support the reactive force from the reinforcing band, wherein, at the end of the tensioning step b), the reinforcing bands are located within a reinforcing area which is substantially rectangular and longer in a given direction, said reinforcing area having a first end area and a second end area located opposite one other in the given direction, wherein, in step a), a first set of reinforcing bands are anchored by their first zones onto the first end area of the construction work, and a second set of reinforcing bands are anchored by their first zones onto the second end area of the construction work, and wherein, in step b), tension is applied to a third set of reinforcing bands containing at least one reinforcing band from the first set and at least one reinforcing band from the second set, tensioning the third set being obtained by means of a spacing tool applying simultaneous tensile forces to the second zones of the reinforcing bands in the third set, the tensile forces applied by the spacing tool moving the second zone or zones of the reinforcing bands in the first set away from the second zone or zones of the reinforcing bands in the second set.
