Definitions

  • the invention relates to a composite anchor of a laminated panel of the type specified in the preamble of claim 1.
  • a known from practice, made of stainless steel composite anchor of this type, the opposite ends of which are releasably embedded in the concrete when forming the supporting and the facing plate, has the shape of a rectangular, flat plate with holes arranged near the narrow sides for passage of anchor rods and the ends of this composite anchor facing the reinforcing steel mats of the supporting or facing plate are pushed through a mesh mat for the tensile connection of the reinforcing steel mats to each other, in order to subsequently be able to insert the anchor rods that can be placed on the reinforcing steel mats.
  • This known composite anchor can be inserted relatively easily and effortlessly through the insulating layer, which usually consists of foam plastic, but with this known composite anchor there is no correct and positionally secure mounting of it on the reinforcing steel mats and relative to them, before they are made from concrete by primary molding
  • the supporting and facing plates are hardened because the composite anchor can hinge around the anchor bars lying along the side of the reinforcing steel mats both when pushing through the insulating plate and when inserting the fresh concrete into the layered composite panel form, so that incorrectly aligned arrangements of the reinforcing steel mats can also result from each other.
  • the object of the invention is now to provide a composite anchor of the type specified in the preamble of claim 1 while maintaining the advantages already achieved in the prior art, namely that the composite anchor is relatively effortlessly inserted through the insulating plate in the production of the layered composite panel and also relatively simple and inexpensive can also be produced in such a way that a considerably simpler production of the layered composite slab and an almost inevitable correct arrangement of both the plate reinforcements relative to one another and the composite anchor relative to the latter can be achieved without reducing the stability of both the composite anchor and the slabs.
  • the aforementioned relatively slender end parts can be inserted, for example, even with a greater or lesser lateral offset of the reinforcing steel mesh meshes or even with reinforcing steel mesh meshes that are smaller than the width of the tie rod for connecting the reinforcing steel meshes together in their meshes.
  • the composite anchor is now held non-rotatably relative to the reinforcing steel mesh by the double support points provided in the area of the hook or hooks. With its straight end part, the composite anchor can also be effortlessly inserted through the insulating layer without fear of unintentional changes in the position of the insulating layer relative to the already connected reinforcing steel mat.
  • the composite anchor can be manufactured inexpensively by cutting it out of sheet metal.
  • An advantageous further development consists in that an end part of the first composite anchor end which decreases in width towards the free end of the first composite anchor end at the other second composite anchor end is opposed by a recess arranged between two, approximately wedge-shaped end parts which are spaced apart and which are provided at the first composite anchor end , approximately wedge-shaped tapering end part is congruent and is arranged symmetrically to an axis running at right angles to the longitudinal axis of the tie rod, wherein preferably the tie rod also has longitudinal sides running parallel to each other, the recess and the wedge-shaped tapered end part arranged on the other tie rod end essentially each the shape of an isosceles triangle have and are arranged symmetrically to the central longitudinal axis.
  • the greatest width of the cutout and the greatest width of the end part arranged at the other composite anchor end and tapering in a wedge shape can be smaller than the total width of the composite anchor.
  • a composite anchor 4 is inserted into a composite layer plate, which essentially consists of a thick support plate 1, a thin facing plate 2 and an insulating plate 3.
  • the supporting and facing plates 1, 2 are made of concrete, in each of which a reinforcing steel mat 5 or 6 are embedded.
  • the insulating plate 3 is made of foam plastic.
  • the essentially flat, cut out of stainless steel sheet, for example 1.5 mm thick composite anchor 4 (particularly clearly in FIGS. 2 to 5) with mutually parallel longitudinal sides 7 has at one end a triangular end part 8 which is symmetrical to the longitudinal central axis of the composite anchor is trained.
  • This end part 8 is smaller than the distance of the long sides 7 from one another.
  • a triangular recess 9 arranged symmetrically to the longitudinal center axis, through which two end parts 10 and 11 tapering in a wedge shape towards their free end result at that composite anchor end.
  • the end part 8 and the recess 9 are congruent so that the composite anchor can be cut out of a sheet metal strip that has the same width as the composite anchor without waste. (Fig. 2).
  • the corners are preferably rounded in order, among other things, to reduce the risk of injury.
  • the end parts 10 and 11 are formed into hooks 12 and 13, respectively, the hook tips of which point towards the end part 8, the hook tips in each case enclosing an angle of approximately 170 ° with the original plane, so that the hooks can be inserted into the hook mouths of similar composite anchors to reduce the space required during storage and transportation of the composite anchors.
  • Holes 14 and 15 are arranged in each hook 12, 13 in the hook tip and the hook part opposite the latter so that, as can be seen from FIG. 1, an anchor rod 16 can be inserted through these holes 14 and 15 in such a way that the anchor rod 16 is placed alongside on a rod of the reinforcing steel mat 5 encompassed by the hooks 12 and 13, whereby the composite anchor 4 is kept at a right angle from the reinforcing steel mat 5 with almost no play.
  • the bending of the end parts 10 and 11 is carried out in such a way that two holes 14 and 15 lie opposite each other so that their common central axis (or the axis of the anchor rod 16) is perpendicular to the composite anchor.
  • the spatial assignment of the holes 14, 15 mentioned can be achieved, for example, by deliberately bending the end parts 10, 11 or by making additional holes on the part of the manufacturer.
  • the latter method has the advantage that it can still be specified on site whether a composite anchor should be installed perpendicular to the plane of the composite layer plate or inclined to it.
  • a plurality of holes 17 arranged at a distance from one another are provided, through which an anchor rod 16, which is supported on the reinforcing steel mat 6, is inserted.
  • the laminated composite panel shown in FIG. 1 was produced as follows by the so-called positive method.
  • the reinforcing steel mat 5 has first been inserted into a layered composite panel mold, not shown, with the aid of known spacers, not shown, at a distance from the bottom of the mold. Then, as can be seen from FIG. 1, the composite anchor 4 is attached to a rod of the reinforcing steel mat 5, and with two holes 14 and 15 of the hooks 12 and 13 penetrating anchor rods 16 have been fixed. Thereafter, the support plate 1 was cast, on which the insulating plate 3 was then placed.
  • the composite anchor 4 has been inserted with its free, straight end part through the insulating plate 3, the composite anchor forming its push-through opening with ease due to its slim shape.
  • the reinforcing steel mat 6 has been inserted in the correct position, with spacers (not shown) ensuring that the reinforcing steel mat 6 is in the correct position from the insulating plate 3, and the end part 8 is inserted through a mesh of the reinforcing steel mat 6 and by means of at least one hole 17 of the end part 8, which is fixed on the reinforcing steel mat 6 and is supported longitudinally on the anchor rod 16.
  • the facing plate was cast.
  • the part protruding over the anchor rod 16 can be bent over effortlessly, so that the entire end part 8 is also completely embedded in the concrete.
  • a plurality of composite anchors 4 are arranged at a distance from one another in a layered composite panel.
  • the facing panel 2 is to be formed first, composite anchors of the type shown in FIG. 5 are to be used, the end part 8 having a hook 18 being connected to the reinforcing steel mat 6 by means of an anchor rod 16, while the end parts 10 and 11 which are not hooked here are fastened to the reinforcing steel mat 5 by means of anchor rods 16.
  • Both types of composite anchors namely those according to FIGS. 1, 3 and 4 and those according to FIG. 5, can be produced from the same sheet metal blank (FIG. 2), which results in considerable manufacturing and storage simplifications.
  • the composite anchor shown in Fig. 6 is suitable for both the positive and the negative manufacturing process. However, this composite anchor is not to be cut out of a sheet metal strip entirely without waste, and in both cases the waste resulting from cutting out the holes 14, 15 and 17 is not taken into account.
  • the invention can also be used for such laminated composite panels, wherein only air is provided as insulation between the support panel and the facing panel.
