  • the invention relates to a reinforced concrete component having at least one anchor rail with a substantially C- or U-shaped cross section comprising an anchor rail back, two anchor rail legs and an anchor rail interior open to the outside of the reinforced concrete component, and with at least one and substantially orthogonal to the anchor rail back of the anchor rail and up or anchors attached in the anchor rail back and away from the anchor rail back.
  • connection between anchor rail and anchor for example by means of the stripping Taumelniettechnik, as in the reference DE 199 07 475 A1 described, be prepared. All other usual connections between anchor rail and anchor are used in the invention, on the type of connection is not important in the invention.
  • substantially plate-shaped reinforced concrete components which have lateral edge regions, is typically close to the edge region an anchor rail, the longitudinal extent of which is typically (but not necessarily) parallel to the edge region, the anchor rail being located near one of the two major surfaces and the armature facing the opposite major surface.
  • an anchor rail typically (but not necessarily) parallel to the edge region, the anchor rail being located near one of the two major surfaces and the armature facing the opposite major surface.
  • the invention is therefore based on the technical problem of specifying a reinforced concrete component, which has an improved carrying capacity, in particular in the edge region and with large transverse forces acting on the anchor rail.
  • the invention teaches that at least one net-shaped reinforcing element is set up, wherein the net-shaped reinforcing element with a main surface of the net-shaped reinforcing element substantially parallel to the surface or at an angle, measured in a cross-sectional area orthogonal to the longitudinal extent of the anchor rail, from 5 ° to 45 ° is arranged to the anchor rail back.
  • the reticular reinforcing element is in any case oriented in the region of the anchor rail either parallel to the anchor rail back or angled against it.
  • the reticular reinforcing element can either be spaced from the anchor rail back, or touch this or abut it, in line contact in the longitudinal direction of the anchor rail or in surface contact.
  • the anchor rail or the anchor rails can be arranged at any point in the reinforced concrete component in accordance with the static requirements.
  • the anchor rail is arranged in an edge region of the reinforced concrete component, the anchor rail extending substantially parallel to the longitudinal extent of the edge region.
  • the carrying capacity of the reinforced concrete component is improved.
  • high, acting on the edge of the reinforced concrete component or the anchor rail transverse forces are absorbed and derived from the net-shaped reinforcing element.
  • the reinforcement Due to the reticular formation, the reinforcement is made Offaxial and thus contributes to a particularly homogeneous load distribution.
  • the meshes can be braided, welded or otherwise connected to each other.
  • a mesh form in question diamond mesh, Langstegmasche, hexagonal mesh, round mesh, square mesh, rectangular mesh, or other special mesh.
  • a mesh such as a rectangular mesh, has a short and a long major axis.

  • the anchor rail has a plurality of anchors attached to the anchor rail back at regular (or even irregular) and predetermined distances, based on the longitudinal extent of the anchor rail. It is also possible that a plurality of transverse anchors is arranged at the anchor rail.
  • the free ends of the anchor rail legs are typically, but not necessarily, on the surface of the steel concrete component so that the anchor rail interior is directly accessible from outside.
  • the type of arrangement of the net-shaped reinforcing element in the anchor rail can be arbitrary. It is essential only a fixation of the position of the net-shaped reinforcing element relative to the anchor rail to the hardening of the concrete.
  • the reticular reinforcing element can be connected directly or via any connecting elements with the anchor rail, for example by means of fixing wires.
  • anchor rail and associated reticulated reinforcing elements are pre-assembled and must be used in the production of reinforced concrete element only in a predetermined position.

  • this distance relates to the distance of the point of the net-shaped reinforcement element closest to the edge region of the reinforced concrete component to the same edge region (and otherwise also relates, for example, to a subsequently described side part of the net-shaped reinforcement element).
  • net-shaped reinforcing element also includes bar grids.
  • the same or different materials can be used independently of each other for anchor rail, armature and reticulated reinforcing element.
