  • Patent number: 8702063
    Abstract: The invention provides a method for pulling strands or sub-groups of strands of a multi-strand cable into a conduit (3). In accordance with this method, a strand or sub-group of strands (2) to be pulled into the conduit is conveyed from one end of the conduit to the other by the movement of a drive element (1) in tension, to which the strand or sub-group of strands is temporarily coupled. In addition, the drive element in tension is designed not to enter a bundle of previously installed strands.

  • Patent number: 8595912
    Abstract: The method comprises the following steps for each of the reinforcing bands: a) anchoring a first zone (2a, 3a, 4a) of the reinforcing band onto the construction work and establishing a free portion of the reinforcing band; b) tensioning the reinforcing band (2, 3, 4) by applying traction to a second zone of the reinforcing band located in the free portion, said traction causing an elongation (d2, d3, d4) of and a reactive force (R2, R3, R4) in the reinforcing band, with 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 itself and/or to the construction work, so as to absorb the reactive force from the reinforcing band within a region of the construction work which can support the reactive force from the reinforcing band.

  • Publication number: 20110257926
    Abstract: Method for the analysis of the thermal behaviour of a structure including an energy-consuming appliance for providing a thermal environment by heating or cooling, the structure being modelled using a thermal model so that a relationship between a theoretical consumption by said appliance and a reference temperature inside the structure satisfies a determined criterion. According to this method, an actual consumption by said appliance, a temperature actually obtained inside the structure and at least one parameter relating to a use of the structure are measured; a variation between the aforesaid relationship and a corresponding relationship between the actual consumption by said appliance and the temperature actually obtained inside the structure are estimated; and when the estimated variation exceeds a threshold, a contribution relating to the use of the structure to said variation is estimated by taking account of said measured parameter.
