An armoury assembly is provided for the protection of a structural material and/or load-carrying element having a longitudinal axis. The armoury assembly is provided longitudinally surrounding the structural material and/or load-carrying element to be protected. The armoury assembly comprises at least two different layers, one being an energy-absorption matrix, the other layer being made of a metal, an alloy or a fibre reinforced polymer having a thickness less than the energy-absorption matrix. Two or more longitudinal channels are provided to the armoury assembly, wherein the channels are substantially parallel to the longitudinal axis of the structural material and/or the load-carrying element.

The present invention relates to a hybrid pipe () for stay cable, comprising a tubular shaped wall (), the wall having an internal face () and an external face (). The hybrid pipe () further comprises at least one reinforcing element (), the reinforcing element () being provided at the wall () to form the hybrid pipe () such that the hybrid pipe () has a higher mechanical properties/resistance such as higher buckling resistance, higher tensile strength and/or a lower thermal dilatation than the wall () itself. The present invention also relates to a cable-stayed system comprising such a hybrid pipe () and a method of manufacturing such a hybrid pipe ().

Hybrid pipe for stay cable and its manufacturing method

Present invention relates to a pipe () for stay cable and a method for tightening the pipe () using stressing means (). The pipe () comprises a tubular shaped wall having an interior and an exterior surface, wherein stressing means () are provided to the exterior surface of the tubular shaped wall of the pipe (), wherein the stressing means () are configured in a way to exert a compression force around the tubular shape wall of the pipe () longitudinally.

A cable anchorage system for anchoring a cable to a support structure in a civil engineering construction comprises an anchorage socket attached to the cable, a support socket attached to the support structure and a longitudinal coupling rod, which couples the anchorage socket to the support socket. The coupling rod comprises a threaded end, which interacts with a counter thread on one of the two parts which are the anchorage socket and the support socket, and a mounting end with a radially extending rod shoulder. The other one of the two parts which are the anchorage socket and the support socket comprises a longitudinal opening for receiving the mounting end of the coupling rod, which opening comprises an inwardly extending abutment shoulder. The rod shoulder abuts on the abutment shoulder in a first longitudinal direction and is slideable within the opening in a second longitudinal direction opposite to the first direction, when the anchorage socket is moved towards the support socket for tuning the cable anchorage system.

Cable anchorage system

The present invention concerns a cable anchorage comprising at least one axial channel for accommodating an elongated element with a sheathed portion and an unsheathed end portion, wherein the channel between a first channel end, proximal to a running part of the elongated element, and a second channel end equipped with immobilising device, a seal element in the channel, a stop element having an end facing said seal element which defines a shoulder, so that an axial displacement of the of the elongated element with respect to the stop element in said channel is possible up to the abutment of the end of the sheathed portion against the shoulder, creating thereby an abutment position of the elongated element in said channel.

A cable anchorage anchors a cable, for example a stay cable having multiple strands (), against a longitudinal tension force. The anchor block () of the anchorage includes multiple channels, through which the strands () are individually threaded. Once in position and tensioned, the space around the strands () in the anchor block () is injected with a liquid, such as a polyurethane, which subsequently sets to form a tough elastic bedding material () within the anchor block (). The elastic bedding material () has a durometer at 23&#xb0; C. in the range 10 to 70 Shore, so as to form bedding cushion extending substantially around the strand () in the strand-channel () along a bedding region () of strand-channel (), the bedding cushion reducing the bending stresses in the strand () by absorbing bending stresses along the bedding region ().

Cable anchorage with bedding material

A cable anchorage is described for anchoring a cable, for example a stay cable comprising multiple strands (), against an axial tension force. Each strand () is individually sealed in an individual channel () of the anchorage against moisture ingress, and each strand () may be removed and replaced individually. A tight-fitting elastic annular seal () is fitted into a recess () in the channel. The annular seal () is inserted from the anchor block end () of the anchorage.

A friction damping device () for damping relative movements between a first structural element and a second structural element of a construction, comprising: &#x2014;a first damping system () for damping a first relative movement component and having a first friction surface () and a second friction surface (), &#x2014;a second damping system () for damping a second relative movement component and having a third friction element () and a fourth friction element (). The first friction surface and the second friction surface of the first and the second damping system form a frictional engagement. The first damping system () and the second damping system () are placed in series.

The present invention relates to a sealing arrangement () for a building element comprising tension members. The sealing arrangement () is arranged to seal off an internal part of the building element. The sealing arrangement () comprises: (a) a first pressing element () of rigid material; (b) a transition pad () of deformable material; (c) a sealing pad () of elastic material; and (d) a second pressing element () comprising a rigid layer () for pressing the transition pad () and the sealing pad () against the first pressing element (). The transition pad (), the sealing pad () and the second pressing element () are provided with holes for the tension elements to pass through. When operationally in place, the first pressing element (), the transition pad (), the sealing pad () and the second pressing element () are pressed together.

Sealing arrangement

The present invention relates to a strand guiding device that comprises a curved body having a first end and a second end. The strand guiding device further comprises at least one channel extending from the first end to the second end inside the strand guiding device, the channel being arranged to be traversed longitudinally by a strand of a cable, and further arranged to hold the strand in place when under tension. The body of the guiding device is filled with a protective material for protecting the strand from corrosion and allowing later removal of the strand.
