    Abstract: 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.

  • Publication number: 20080250576
    Abstract: A tension member is provided for structures, in particular a cable stay for a cable-stayed bridge, in which one or more tension elements, such as steel rods, steel wires, or stranded steel wires, run inside a tubular sheath. The tension elements fill only a portion of the cross-section of the tubular sheath, so that a remaining unoccupied area is left. In order to prevent the tension elements from moving in the transverse direction with respect to the tension member, there is arranged in the remaining unoccupied area of the tubular sheath a filler body that extends over a limited longitudinal section of the tension member and includes a deformable sheath, which tightly encloses a hollow space that is delimited on all sides and can be filled with a filler medium.

  • Patent number: 7299516
    Abstract: A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in the open area is encapsulated by sheathing, and which in the area of a rerouting point, for example, at the pylon of a cable-stayed bridge, extends inside a saddle pipe in a canal having the shape of a circular arc. In order to avoid impairments at the ends of the saddle pipe when sheathing is connected to the structure, the saddle pipe is extended in the shape of a circular arc beyond a tangential exit of the bundle by a length L so that the bundle is exposed at an end of the saddle pipe without any risk of abutting.

  • Patent number: 7281287
    Abstract: There is disclosed a prop-type damping device which effectively consumes energy of up-and-down vibration on a main girder of a bridge caused by earthquakes, winds, passing vehicles or the like to prolong a life of the bridge and improve comfort for bridge users with a simple constitution. The prop-type damping device comprises: an inclined prop member having a higher end thereof connected to a lower part of a main girder of a bridge to be horizontally movable relative to the same, and a lower end thereof connected to a position below a main girder supporting point of a pier or abutment for supporting the main girder to permit up-and-down movement of the higher end; and a damper connected to the higher end of the prop member and the main girder lower part to brake relative horizontal movements therebetween.

  • Patent number: 7200886
    Abstract: A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in its open area is encapsulated by sheathing, and which within the structure extends inside a guide canal that is formed by a recess pipe. The sheathing—sealing off the front side of the guide canal—is thereby directly or indirectly connected to the structure. Between the sheathing and the entrance point of the tension member into the structure, a connecting pipe is arranged, which on the one hand is detachably connected to the sheathing and on the other hand is connected to the structure by a flange plate.

  • Patent number: 7124460
    Abstract: 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.

  • Patent number: 7003835
    Abstract: A cable-stay cradle system (“cradle system”) for cable stayed bridges is mounted onto a cable stay, the opposite ends of which are attached to anchors on a bridge deck. The cradle system is disposed along the length of the cable stay and located in a pre-formed opening in a pylon. The cradle system includes axially spaced sleeve centering plates that have radially spaced holes through which the cable strands of the cable stay are threaded. The cradle system ensures that a distance from center-points of adjacent cable strands remains essentially constant along the entire length of the cradle system. The invention also provides a method of installing a cable stay including a cradle system, which includes the steps of threading the cable stay through the opening in the pylon so as to locate the cradle system in the opening, and attaching the cable stay to anchors on the bridge deck.

  • Patent number: 6814523
    Abstract: Connecting element for joining two support members (2, 3) absorbing tensile forces, which connecting element (1) comprises at least a first and a second casing body (5, 6) with a through-hole (7) for receiving the respective support members (2, 3), which casing bodies (5, 6) can be joined together by way of a joining section (9) at a first end (11) of each casing body (5, 6), the opposing second end (13) of each casing body (5, 6) being provided with locking members (15, 16) for holding the support members (2, 3) fast. In a working position the locking member (15, 16) of at least one casing body (5, 6) produces an axial locking of the support member (2, 3) running through the casing body (5, 6) by way of a stop part (20) created on the support member (2, 3) within the area of the second end (13) of the casing body (5, 6).

  • Publication number: 20040128776
    Abstract: A tensioning element (1), especially for the suspension of building components, is provided with a number of wires (3) arranged approximately in parallel forming a wire cable (2). These wires (3) are anchored at each end in an end piece (6) absorbing the tensile forces exerted on the wire cable. The end piece (6) is at least partly provided with a plastic deformable sheath (6b) which serves to house one end of a wire cable, where this sheath (6b) is compressible with the end of the wire cable. This enables rapid anchoring of the wire cable in the end piece and this guarantees a high breaking load.

  • Patent number: 6728987
    Abstract: A method of modifying the vertical profile of a cable supported bridge. The method consists of sequentially adjusting a lower end of a series of supporting cables downward relative to the bridge superstructure and sequentially adjusting an attachment structure associated with the lower end of each cable to maintain the distance each cable has been adjusted. The adjustments preferably proceeds according to a pre-specified plan known as an adjustment sequence. The preparation of an adjustment sequence according to the methods disclosed allows the modification of the vertical profile of the bridge superstructure to be completed without overstressing any bridge members, and with predictable results.

  • Patent number: 6715176
    Abstract: A device for fixing together a construction element and a structural cable, the device has a rigid housing connected to the construction element and surrounding the cable, a wedging structure comprising at least one deformable material arranged between the cable and housing, and load transmitting means arranged to exert a longitudinal compressive force, parallel to the cable, on the wedging structure. The wedging structure is pressed against the cable and the housing under the action of the longitudinal compressive force, so as to offer resistance to movement of the housing and of the construction element parallel to the cable.
