Patent number: 7779499Abstract: A method for assembly of a stay includes a series of steps that include connecting in the vicinity of an anchoring zone, a new group of N reinforcements to a shuttle located within the sheath of a stay to be installed. The shuttle is driven towards another anchoring zone by means of driving and guiding means. When the shuttle has arrived substantially in the vicinity of the anchoring zone, and as long as entangling is detected between the driving and guiding means in a portion contained substantially between the shuttle and the first anchoring zone, the shuttle is rotated about its main axis in the opposite direction to the said entangling. The group of N reinforcements is then separated from the shuttle. Each reinforcement of the group is tensioned between the anchoring zones. The preceding steps are repeated until the installation of the reinforcements is completed.Type: GrantFiled: August 18, 2004Date of Patent: August 24, 2010Assignee: Freyssinet International (STUP)Inventors: Benoit Lecinq, Sebastien Petit, Francois Bignon, Jerome Stubler

Patent number: 7739766Abstract: A stay comprises an inclined casing and a bundle of substantially parallel taut reinforcements lodged in the casing and individually anchored in a first and a second anchoring region. According to the invention, the casing and some of the reinforcements are installed by applying substantially uniform tension values to the reinforcements, then several iterations of the following steps are formed: compacting the installed reinforcements, at least at one end of the casing; slipping a further group of reinforcements along inside the casing, in a space left available by the compacted reinforcements; and tensioning each reinforcement of the further group between the first and second anchoring regions so that all the installed reinforcements exhibit substantially uniform tension values.Type: GrantFiled: December 18, 2003Date of Patent: June 22, 2010Assignee: Freyssinet International (STUP)Inventors: Benoit Lecinq, Jean-Pierre Messein, Jean-Claude Percheron, Craig Robertson

Patent number: 7347227Abstract: In order to reinforce a cylindrical pipeline, in particular an underground water supply pipeline, prestressing reinforcements are placed and tensioned around it. In a zone where the pipeline has a radial projection, for example providing a manhole for access to the inside of the pipeline, the prestressing reinforcements are deflected to bypass the radial projection so that the reinforcements, located in the same layer on a side of the pipeline opposite the side having the projection, are distributed in a plurality of layers on this side having the protuberance.Type: GrantFiled: March 19, 2004Date of Patent: March 25, 2008Assignee: Freyssinet International (STUP)Inventors: Ivica Zivanovic, Benoît Lecinq, Dominique Deschamps, Ronan Solet

Patent number: 7234280Abstract: The anchoring device, for anchoring at least two reinforcements for prestressing a civil engineering works structure, has a block through which there pass at least two pairs of anchoring orifices arranged symmetrically on each side of a mid-plane of the block. The two orifices of each pair have axes substantially parallel to the mid-plane and are directed toward two opposite sides of the block to take, respectively, two ends of a taut reinforcement surrounding the structure. The block has a bearing zone pressed against the structure in response to the tension in the reinforcements.Type: GrantFiled: March 8, 2002Date of Patent: June 26, 2007Assignee: Freyssinet International (STUP)Inventors: Jean-François Nieto, Benoît Lecinq, Fernand De Melo

Patent number: 7124460Abstract: The cable, in particular of the stay cable type, comprises a set of traction reinforcements, two devices for anchoring the reinforcements in two respective zones of the construction, the reinforcements being spaced apart from one another at the anchoring devices, means for deviating the reinforcements in order to cause the reinforcements to converge toward a running part of the cable into a substantially parallel bundle which is more compact than at the anchoring devices, and a guide member which is in closely set contact around the set of reinforcements. This member has an inner surface, the cross section of which is adapted to the peripheral shape of the parallel bundle and the longitudinal section of which has a convex curvature which, over the length of the guide member, allows angular deflections of the reinforcements which are substantially greater than the maximum angle of convergence of the reinforcements between the anchoring device and the running part of the cable.Type: GrantFiled: March 24, 2003Date of Patent: October 24, 2006Assignee: Freyssinet International (Stup)Inventors: Benoit Lecinq, Jean-Pierre Messein
