  • Patent number: 5729951
    Abstract: An anchoring device for the construction industry has an anchor rail that is C-shaped in cross-section and has a hollow interior so that the anchor rail has a back and legs connected to the back. The legs have angled free ends pointing toward one another and delimiting therebetween a longitudinal slot. The back has outwardly extending projections, each having an opening. Each opening has a double cone rim widening radially outwardly from the opening with radially outwardly diverging first and second conical surfaces. The double cone has an outer edge facing outwardly relative to the hollow interior. A plurality of anchors is connected to the anchor rail, whereby each one of the anchors is received in one of the openings and attached thereto by plastic material deformation of the anchor rail and/or the anchor. The anchor has a cylindrical shaft with a head and a base opposite the head. The base of the shaft is positioned in the opening.

  • Patent number: 5649782
    Abstract: A transport anchor for transporting a heavy part, which anchor is embedded in the heavy part, includes a sleeve having an inner thread for receiving a load bearing member. The sleeve has a first section with an exterior end face positioned flush with the exterior surface of the heavy part. The sleeve has a second section with a receiving member for an anchoring element of the heavy part. A first plug with an outer thread is threaded into the inner thread of the sleeve and is moveable along the inner thread. The first plug has a plug end face facing outwardly relative to the heavy part. The load bearing member can frictionally engage the plug end face of the first plug. The load bearing member has a base body with an outer thread for cooperation with the inner thread of the sleeve.

  • Patent number: 5560664
    Abstract: A coupling device for coupling a cable of a lifting device to a prefabricated component has a receiving member for receiving the cable and a fastener for connecting the receiving member to the prefabricated component such that the receiving member is rotatably supported at the prefabricated component. The receiving member is embodied so as to rest at the surface of the prefabricated component. The receiving member has a cable guide portion for guiding the cable. The cable guide portion extends substantially parallel to the surface of the prefabricated component and is located directly adjacent to that surface. Preferably, the receiving member is in the form of a plate and the cable guide portion is arc-shaped.
