Definitions

  • the invention relates to a building according to claim 1 and a profile rail arrangement according to claim 7.
  • anchor channels known which are poured into a concrete body so that a rail slot of the respective anchor rail appears.
  • Hammer head elements can be anchored in the anchor rail and thus on the concrete body via this rail slot.
  • WO09083002 A1 shows an anchor rail which is provided with additional transverse anchors.
  • the sustainability of the anchor rail especially in the edge region of a concrete body at high shear forces to be improved.
  • Another anchor channel with transverse anchors is evident from EP2907932 A1 (WO14058151 A1).
  • the object of the invention is to achieve particularly high load values in the case of profile rails in a particularly simple and reliable manner, which are embedded in concrete bodies, in particular near the edges, in particular in the case of transverse loads.
  • An inventive structure has:
  • a concrete body having a first surface and an second surface disposed at an angle to the first surface
  • the rail has a rail body with a extending in the direction of the longitudinal axis of the rail rail slot, and wherein the rail on the first surface of the concrete body comes to light, and a reinforcing body, which appears on the second surface of the concrete body, and which at least partially overlaps the rail body, viewed in the direction of the longitudinal axis of the rail.
  • a first basic idea of the invention can be seen in addition to reinforce the concrete body in the vicinity of the edge in addition.
  • the rail body is preceded by a reinforcing body near the edge.
  • This idea of the invention is based on the recognition that with transverse loading of an arranged near the edge rail not the rail itself, but also the surrounding concrete can be load-limiting, since the edge near concrete at transverse load transverse to the rail and the edge may possibly break across the edge , This is where the invention starts and provides with the reinforcement body an element which can counteract this process effectively, so that the load behavior can be improved in a simple manner.
  • the reinforcing body reaches as far as the surface of the concrete body lying in front of the rail body and emerges on this surface.
  • Rail bodies or reinforcing bodies thus appear on surfaces that are separated by the edge.
  • a particularly efficient reinforcement with correspondingly good load values can be achieved here, among other things because a particularly large distance can be reinforced.
  • this embodiment allows a particularly simple positioning of the reinforcing body in the glazing of the concrete body, since the reinforcing body can be easily attached with its projecting later on the second surface contact surface on the provided for Glessen the concrete body shuttering element.
  • the second surface may in particular be arranged at right angles to the first surface.
  • the aforesaid edge is formed between the first surface and the second surface.
  • the longitudinal axis of the rail expediently runs parallel to this edge.
  • the rail is conveniently a C-rail.
  • the rail slot serves to insert hammerhead elements, such as a hammerhead bolt or a sliding block, into the rail body, where the hammerhead element can then be secured by rotation about an axis perpendicular to the rail slot in the rail.
  • the profile rail appears on the first surface, in particular in the region of the rail slot of the profile rail. Under the longitudinal axis of Profile rail can be understood in the usual way in particular that axis with the largest extent.
  • a head element of the reinforcing body described in more detail below emerges on the second surface of the concrete body, and that this head element of the reinforcing body at least partially overlaps the rail body, viewed in the direction of the longitudinal axis of the profile rail.
  • the fact that the reinforcing body, in particular its head element, the profile rail overlaps at least partially considered in the direction of the longitudinal axis of the rail can in particular include that the reinforcing body or its head element of the rail is at least partially transversely upstream and / or that the reinforcing body or its head element at least partially abeam away from the rail.
  • the reinforcing body and / or the head element is preferably made of a metal material, which may be advantageous in terms of the power consumption.
  • the reinforcing body in particular its head element, completely overlaps the rail body, viewed in the direction of the longitudinal axis of the profile rail. Accordingly, therefore, the reinforcing body or its head element is at least as long as the rail, particularly preferably longer than the rail. As a result, the load behavior can be further improved.
  • the reinforcing body preferably has a head element, which, among other things, may allow a particularly simple construction.
  • the reinforcing body has at least one tension element which protrudes from the head element, in particular towards the rail.
  • the tension element is particularly suitable for receiving tensile loads and initiation of tensile loads in the surrounding concrete.
  • the tension element may for example be a round rod, with or without profiling, or a metal band.
  • the tension element can also be referred to as a reinforcing bar.
  • the tension element consists of metal.
  • the at least one tension element is connected to the head element, for example, welded.

In order to hold the tension element in the prestressed state, a tension nut can be screwed onto the tension element, which is supported on the head element.
  • the at least one tension element crosses the profile rail, in particular when viewed perpendicular to the first surface and / or when viewed perpendicular to a slot plane spanned by the rail slot.
  • the at least one tension element accordingly extends from the second surface behind the rail body, so that a particularly good introduction of force into the concrete body can be provided.
  • the head element is expediently a head plate, preferably a flat cuboid, which may be advantageous in terms of the production effort and the introduction of force.
  • the reinforcing body in particular its head element, at least one passage opening for a fastening pin, for example a nail having, which allows a particularly simple installation of the reinforcing body on the formwork element.
  • the rail has anchors which are arranged on the rail body, that is, that the rail is an anchor rail.
  • the anchors are expediently arranged on a rail slot facing away from the back of the rail body on the rail body.
  • the at least one tension element expediently extends between the anchors and / or crosses the anchor when viewed in the direction of the longitudinal axis of the profile rail.
  • the invention also relates to an existing before the Glessen the concrete body element, namely a suitable pouring into concrete profile rail assembly, with a rail, wherein the rail has a rail body with a extending in the direction of the longitudinal axis of the rail rail slot, and a Reinforcing, which at least partially overlaps the rail, preferably on the head element of the reinforcing body, viewed in the direction of the longitudinal axis of the rail, and having a contact surface for a formwork element.
  • this contact surface of the reinforcing body can be easily positioned before the glazing of the concrete body. After glazing, the contact surface of the reinforcing body can then protrude from a surface of the concrete body.
  • the contact surface for the formwork element preferably extends at an angle, in particular at right angles, to a plane defined by the rail slot slot plane, which is advantageous in terms of the structural design and power transmission in near-edge applications.
  • a further preferred embodiment of the invention is that the reinforcing body - is already connected to the rail before pouring into concrete, ie outside the concrete.
  • the profile rail assembly can be mounted in a particularly simple and reliable manner.
  • the connection of the reinforcement body with the rail can be given in particular to at least one tension element of the reinforcement body.
  • the reinforcing body and the rail can be welded, for example.
