  • Patent number: 8925279
    Abstract: Anchoring devices and systems are disclosed for use with elongated reinforcement members such as FRP, SRP, metallic bars, or cables. Such devices and systems impart a compressive stress into a static structure having the elongated reinforcement member running there through or there along. An anchoring system can include an anchor block that includes a front end surface for contacting the static structure, an axial bore for receiving the elongated reinforcement member, and clamping members that work with fasteners to provide a clamping force. The bore may be tapered and the fasteners optionally provide different clamping levels to reduce the stress on the elongated reinforcement member near the front end surface. The disclosed systems also include pre-stressing devices that can be used with the disclosed anchor systems, and that can place a tensile force on the elongated reinforcement members to also impart a compressive force on the static structure.

    Abstract: Anchoring devices and systems are disclosed for use with elongated reinforcement members such as FRP, SRP, metallic bars, or cables. Such devices and systems impart a compressive stress into a static structure having the elongated reinforcement member running therethrough or therealong. An anchoring system can include an anchor block that includes a front end surface for contacting the static structure, an axial bore for receiving the elongated reinforcement member, and clamping members that, when closed, exert a radial clamping force on a reinforcement member in the axial bore. A tensioning and anchoring system may include one or more tensioners integrally connected to an anchor block. At least one sleeve may be secured to the anchor block and cooperate with a bolt that displaces the anchor block to place a tensile force on the elongated reinforcement member and impart a compressive force on the static structure.

  • Patent number: 8881493
    Abstract: Disclosed is a force-applying element including a tensioning anchor for anchoring a tape-shaped material to a support structure. The tape-shaped material is pretensioned by means of the tensioning anchor. An extension element is disposed in the transition area between the tensioning anchor and the tape-shaped material following the tensioning process. The extension element is effectively connected to the tape-shaped material and the tensioning anchor.

  • Patent number: 8869476
    Abstract: The present invention relates to a sealing arrangement (202) for a building element comprising tension members. The sealing arrangement (202) is arranged to seal off an internal part of the building element. The sealing arrangement (202) comprises: (a) a first pressing element (500) of rigid material; (b) a transition pad (501) of deformable material; (c) a sealing pad (503) of elastic material; and (d) a second pressing element (505; 507) comprising a rigid layer (507) for pressing the transition pad (501) and the sealing pad (503) against the first pressing element (500). The transition pad (501), the sealing pad (503) and the second pressing element (505; 507) are provided with holes for the tension elements to pass through. When operationally in place, the first pressing element (500), the transition pad (501), the sealing pad (503) and the second pressing element (505; 507) are pressed together.

  • Publication number: 20140245678
    Abstract: A wedge for a concrete post-tension reinforcement anchorage system is shaped such that the compressive force on the tendon after tensioning of the anchorage system is substantially evenly distributed over a length of the outer surface of the tendon that is engaged by the internal surface of the wedge. The external surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being larger than the first taper angle. The internal surface of the wedge may have a first section with a first taper angle and a second section with a second taper angle, the second taper angle being greater than the first taper angle. An anchor with a bore with two taper angles and tooth profiles of threading patterns on the internal surface of the wedge are also disclosed.

  • Publication number: 20140237914
    Abstract: The present invention relates to a windfence supporting tower with tension-integrity, comprising a tubular metal tower comprising a central tubular post (1) and four inclined tubular structural tensile elements (2) attached to the post via the coupling ring (3) and the lower ends attached to the free ends of a yoke of compression tubes (4), which is in turn attached to the post (1) by means of the reaction flange of the yoke (5), further receiving at the free ends of the yoke (4) four vertical tensile structural elements (6) which, by means of tensioners (7), are tensioned and anchored to the ground through four independent foundations (8) located around the foundation of the central tube. These vertical ties pull on the connection point of the yoke and in turn the inclined structural elements connected to the coupling ring, thereby providing stability with tension-integrity, which is the main feature of the present supporting tower for absorbing forces caused by the wind.

  • Patent number: 8813446
    Abstract: An insert for embedment in a concrete component during casting, having a tubular cavity for receiving a threaded anchorage member, the tubular cavity having an opening arranged to face outward of the concrete component when cast for insertion of the threaded anchorage member, wherein the insert is externally tapered such that, when the insert is embedded in the concrete component and the anchorage member is threadedly engaged within the tubular cavity, axial loading applied to the anchorage member in a sense to withdraw the anchorage member from the insert causes reactional force from the surrounding concrete to be applied to the insert in a direction radially inwardly of the insert, and wherein the insert is formed of deformable plastic material such that said reactional force in turn causes the insert to exert force radially inwardly upon the anchorage member.
