Definitions

  • reinforcement nets are not only understood to be flat structures, but more generally three-dimensional structures formed from such networks by means of bends.
  • reinforcement cage is also used.
  • Conventionally, such a reinforcement cage is often formed on the building site at the place of installation and tied with special wires. This is extremely labor-intensive, but has the advantage that the reinforcement cage can be easily adapted to the specific building conditions.
  • prefabricated reinforcement baskets must therefore be very carefully thought out so that they can be used in as many different ways as possible, despite their specified and thus restricting the application.
  • the legs of the bars bent at right angles are connected by binding with flat nets on the wall and / or the floor-ceiling slab.
  • the disadvantage of this solution can be seen in the fact that the ironlayer takes up relatively little work.
  • the reinforcement network described offers little help, in particular when creating a floor / ceiling slab, which usually has an upper and a lower armouring.
  • a reinforcement cage according to CH-A 642 131 serves considerably better.
  • This armouring basket consists of a number of identical, parallel, hairpin-shaped brackets.
  • the brackets are inseparably connected to one another by at least three bars lying in two planes arranged at right angles to one another.
  • two such reinforcement baskets are inserted into each other perpendicular to each other.
  • the vertically extending reinforcement cage stands on the narrow end of the hairpin-shaped bow.
  • the vertical baskets with the horizontally lying baskets must be fastened with the known binding wires. In these corner areas, however, accessibility is extremely poor, so that setting is difficult.
  • the element can only be used to a limited extent, particularly when used to create the reinforcements of a connection of a floor-ceiling plate to a wall or two walls. If, for example, the wall is only reinforced with one layer, connection problems arise.
  • a prefabricated reinforcement cage which is characterized by the fact that it consists of a number of long cross bars arranged in parallel at equal distances, each of which is connected at the two ends by a longitudinal bar, and at least approximately centrally between two adjacent long bars Cross bars parallel to these short cross bars extending from at least the middle of the length of the long cross bars to approximately one of the two terminal longitudinal bars, the central region of the long cross bars and the short cross bars located there being connected to one another by three parallel longitudinal bars are, and that the long cross bars are bent approximately centrally between two of the three longitudinal bars running in the central area by 90 ° and the free ends of the short bars are also bent by 90 ° in a parallel plane over the legs of the long cross bars.
  • the short crossbars When installed, the short crossbars come into the pressure range of the reinforced concrete structures, which is why the short crossbars can be up to 50% smaller in diameter than the long crossbars. This can save up to around a third of the total iron weight compared to conventional reinforcement nets.
  • Two of these longitudinal bars 4, 5 run at the same distance on either side of the fictitious center line m at the same distance from it.
  • a third longitudinal bar runs at the same distance as the two aforementioned longitudinal bars 4, 5 from the center line m to the longitudinal bar 5 and cross the short cross bars 3 and the long cross bars 1. At all intersections of two bars, these are connected to one another by spot welds.
  • the flat net shown in FIG. 1 is finally bent by two bends into the shape shown in the side view in FIG. 2 to form the reinforcement cage according to the invention.
  • a first bend all cross bars are bent at a right angle around the center line m.
  • the long crossbars 1 are formed into the two long legs 1 'and 1 "running perpendicular to one another, and the short crossbars 33 are optionally angled once.
  • a second bend around a straight line b only the short crossbars 3 now become and 33 by approximately 90 ° from the plane in which the legs 1 'of the long crossbars 1 are bent, so that the legs 3' of the short crossbars 3 and 33, at least approximately parallel to the other legs 1 "of the long crossbars 1 run.
  • the bent legs 1 "and 3 ' form a U with legs of different lengths.
  • the short cross bars 3 have, for example, a diameter that is approximately 40% smaller than the long cross bars 1. This can save a considerable amount of iron. If the legs 1 "and 3 'belonged to the same crossbar, this could not be achieved.
  • FIGS. 3 and 4 schematically show two application examples for the reinforcement baskets according to the invention.
  • Figure 3 shows a transition from a floor-ceiling slab P to a retaining wall M. Both concrete components are provided with a two-layer reinforcement.
  • the reinforcement cage is placed on the customary, lattice-shaped flat reinforcement net 10, which, like all other reinforcement irons not belonging to the reinforcement cage, is shown in broken lines so that the legs 3 'and 1 ", each lying in two parallel planes, are directed vertically upwards Already laid, flat reinforcement mesh 10 and the reinforcement cage can now be easily accessed, outside the actual corner area, by means of binding wires on the legs 1 'coming to lie in the floor cover plate and the longitudinal bar 2 attached to them the free ends of the relatively short legs 3 'of the short crossbars 3 are pushed, which often eliminates the need for additional binding by means of wires on the reinforcement cage.
  • the two flat reinforcement nets 12, 13 of the retaining wall M can now also simply be placed in the reinforcement cage and with the legs 1 "or 3 'are connected. This in turn happens outside of the actual corner area.
  • the reinforcing grids 12, 13 can also be attached both or only one on the outside of the two legs 1 ", 3 'forming a U. If the connection is one between a floor cover plate P and a partition T, see above the reinforcement cage can also be used rotated by 90 ° . However, all of the advantages of the simple handling described above are retained.
  • the cage can be placed again on the lower flat reinforcement net 10 and connected to the lower, longer legs 1 ".
