  • Patent number: 4878640
    Abstract: An anchoring rail that includes a hollow section which is provided with a slot that extends in the longitudinal direction, with each of the sides of the slot being provided with a toothing that is engaged by a corresponding toothing on a latching plate that is wider than the slot and is part of a mounting element. In order to increase the capacity of the mounting element to take up loads applied in the longitudinal direction of the anchoring rail, without the mounting element being displaced, the load-carrying surfaces of the toothings, which are in contact with each other in the longitudinal direction of the anchoring rail, are oriented at right angles to the plane defined by the slot.

  • Patent number: 4624089
    Abstract: A tie anchor for use in reinforced sandwich panels of cast concrete, to support a face panel on a carrier panel by reaching through an intermediate insulating panel, the tie anchor being a sheet metal stamping with a central A-shaped end portion on one axial end and a V-shaped recess flanked by two tapered end portions on the other axial end. Hook portions formed of the tapered end portions are engageable over a rod of a reinforcing steel rod mesh and attachable thereto by means of positioning rods which are inserted through transverse positioning bores in the hook portions.

  • Patent number: 4283896
    Abstract: Tie anchor for sandwich panels of reinforced concrete in the form of a metal strip of undulated zigzag shape whose loop portions are anchored in the concrete panel layers and whose connecting leg portions reach through the intermediate insulating layer. Two central leg portions of the tie anchor are oppositely inclined to form a rigid central connecting point between the panel layers, while all other leg portions are parallel, to allow for limited panel displacements, under unequal thermal expansion.
