Definitions

  • the invention relates to a pourable anchor rail, the type mentioned in the preamble of claim 1.
  • Such anchor channels are used to create flexible attachment points on a cast component, eg. As concrete, previously in the formwork of the component, eg. As a wall or ceiling, inserted and poured in the Glessen of the component in this.
  • Fastening elements are fixed directly to the anchor channels by means of rail nuts, rear grip parts or hammer head bolts. The loads are transferred via the rail geometry and the anchor elements into the hardened component.
  • a pourable anchor rail with a rail body and anchor elements fixed thereto is known.
  • the rail body has a extending in the longitudinal extent of the rail body, rectangular receiving space which is accessible via a limited opening edges of mounting and laterally from opposite side walls and opposite the mounting opening is bounded by a rear wall.
  • the side walls enclose a right angle with a plane defined by the mounting opening.
  • transverse forces acting on an armature rail cast in the component and lateral forces acting obliquely on the anchor rail loads acting in one of the Mounting opening clamped plane act.
  • a disadvantage of the known solution is that, in particular in an arrangement of the anchor rail in an edge region of the component under transverse force load a failure crack occurs, starting from the transition of the side wall to the rear wall runs obliquely to the edge of the component and generates a correspondingly large outbreak (floe) in the component.
  • the object of the invention is to provide a pourable anchor rail, which has an improved carrying capacity with respect to transverse forces.
  • a crack initiator means is provided on at least one of the sidewalls.
  • the crack initiator means two cracks are generated in a near-edge arrangement of the anchor rail and under load by lateral forces in the component instead of a crack, which do not intersect and therefore do not affect each other.
  • the crack initiator means arranged on the at least one side wall ensures a controlled formation of the first crack and thus also of the second crack.
  • the first of the second crack formation different cracking two independent break-off cone are generated.
  • the position of the significant pressure resultant is displaced away from the surface by a distance defined by the crack initiator means into the component. This results in the eruption in the near-edge region of the component a larger fracture surface than is the case with an anchor rail, is formed in the transverse force load only a crack.
  • the anchor rail according to the invention can be positioned closer to the edge of the component or, with the same edge distance, a higher transverse force can be applied to the cast anchor rail.
  • both, opposite side walls are each provided with a crack initiator means, so that in the positioning of the anchor rail in the component no special orientation of the same with respect to the edge of the component is taken into account.
  • the crack initiator means on the side walls are advantageously formed similar.
  • the mounting aperture biases one plane and the crack initiator means is spaced from that plane by a maximum of 0.75 times the overall height of the rail body.
  • the crack initiator means is preferably formed by a material reduction provided in regions in the at least one side wall, which forms a joint in the corresponding side wall of the rail body.
  • the material reduction is provided for example on one side or on both sides of the corresponding side wall of the rail body.
  • the material reductions are advantageously arranged symmetrically to each other and advantageously designed the same.
  • the material reinforcement is, for example, during molding of the rail body, z. B. in a rolling process, formed directly on the material portion which forms the corresponding side wall in the formed state.
  • the crack initiator means is formed by a material reinforcement provided in regions in the at least one side wall, whereby a notch effect is exerted on the material of the component in the region of the crack initiator means.
  • This notch effect is advantageous, especially in brittle materials, such as concrete, crack initiation.
  • the material reinforcement in cross section has a triangular configuration, so that its tip defines the starting point of the first crack.
  • the material reinforcement is provided for example on one side or on both sides of the corresponding side wall of the rail body.
  • the Mate ria reinforcements are advantageously arranged symmetrically to each other and advantageously formed the same.
  • the material reinforcement is, for example, during molding of the rail body, z.
  • differently shaped crack initiator means may also be provided on the side walls on a rail body.
  • One type of crack initiator means is provided on the receiving space side of the side walls and another type of crack initiator is arranged on the side of the side walls facing away from the receiving space.
  • the crack initiator is provided on the side facing away from the receiving space of the rail body side of at least one side wall, on the one hand an advantageous notch effect in the material of the component and thus an advantageously defined formation of the first crack is ensured and on the other hand, the receiving space of the rail body not inwardly projecting Elements, e.g. B. for the arrangement of Anbindemaschine restricted.
  • the crack initiator is formed by varying the wall thickness of the at least one side wall, wherein advantageously in the region of the side wall with the lowest material thickness, a joint is formed, which is crack initiating.
  • varying the wall thickness over the extension of the corresponding side wall of the power flow can be adjusted so that when the deformation of the rail body under load locally increased pressure in the component arise, which initiate the first crack. Further, this makes optimum use of the material of the rail body in relation to transverse and tensile load.
  • the variation of the wall thickness of the corresponding side wall may be additionally combined with another type of crack initiator means to further influence the initiation of the first crack.
  • the variation of the wall thickness of the at least one side wall for example, during molding of the rail body, z. B. in a rolling process, formed directly on the material portion which forms the corresponding side wall in the formed state.
  • the crack initiator means is an edge on the side facing away from the receiving space of the rail body of the at least one side wall, which is formed by a first wall portion of the at least one side wall and a second wall portion of the at least one side wall, wherein the first wall portion and the second Wall section in each case with respect to a plane spanned by the mounting hole level include different angles with this. Due to the deflecting forces arising when loading the anchor rail, in addition to the notch effect as a result of the edge, a splitting effect is created, which has an increased crack-initiating effect.
  • an advantageous bearing behavior of the anchor rail due to this inclination of the first wall sections of the corresponding side wall, an advantageous bearing behavior of the anchor rail, so that a simple optimization of the wall thicknesses of the rail body is possible, which leads to advantageous material savings in the production of the rail body and thus the anchor rail.
  • this embodiment corresponds to the anchor rail, the first angle 90 ° to 120 °, whereby the force is introduced substantially in the region of the first wall portion of the side wall in the component.
  • This force acts in the direction of the surface of the component, which leads to an earlier formation of the first crack and thus a rapid release of the near-surface portion of the component under transverse force.
  • an anchor rail to create attachment points z. B. for curtain wall elements is advantageously a second angle in a shallower area, starting from 20 ° selected.

  • the second wall section of one of the side walls can also run along a curvature, with which the force curve in the rail body can additionally be optimized for deriving the force via the anchor element into the component.
  • the second wall section extends along a circular arc.
