Definitions

  • the present invention relates to an anchoring element for casting in concrete, with an anchor rail with a plurality of anchor webs and a strip-shaped receptacle for mounting fasteners, with at least one retaining bracket being fixed to the anchor rail, which engages over the anchor rail perpendicular to its longitudinal direction and over the the anchor rail can be fixed to a formwork component, with at least one flange protruding laterally from the anchor rail being formed on the retaining bracket, and a method for assembling an anchor rail in a concrete structure.
  • DE 102008029838 A1 discloses an anchor rail for fixing loading fastening means on a structure made of concrete, the anchor rail having a plurality of anchor bars which are cast into the concrete.
  • the anchor rail In order to position such an anchor rail before concrete is poured, it is known to fix the anchor rail to a formwork component by means of nails. After the concrete has been poured, the formwork component is then removed, where the nails remain in the concrete.
  • the nails in the assembly area of the anchor rail are disruptive.
  • the introduction of nails into small openings on the anchor rail is also complex in terms of assembly, since the nails cannot be shot with so-called nail guns.
  • US 2005/0217197 A1 discloses a clamp for fixing a rail in a concrete component, in which two sleeve-shaped fastening elements are formed on a bracket, which are then torn off when a formwork is removed. Openings are formed in the formwork, into which the sleeve-shaped fastening elements can be inserted. The assembly of these Klam numbers with the fasteners is therefore complex.
  • a rail is fixed to formwork using brackets in order to cast the rail in a concrete component.
  • the bracket is attached to the formwork with nails that are intended to be pulled out of the bracket when the formwork is removed. If the nails get caught in the clamp remain, the tips of the nails protrude from the concrete part and pose a risk of injury.
  • an anchor rail with a plurality of anchor webs and a strip-shaped receptacle for Mon days of fasteners, such as hammer head screws is provided, the anchor rail being fixed via at least one bracket, via which the anchor rail can be fixed to a formwork component.
  • the retaining bracket enables secure positioning and alignment of the anchor rail on the formwork component and an indirect form-fitting fastening of the anchor rail, since the anchor rail can be fixed to the formwork component via the at least one retaining bracket.
  • the fixation of the retaining brackets makes it easier to assemble the anchor rail before pouring concrete.
  • the at least one retaining bracket engages over the anchor rail perpendicular to its longitudinal direction. At least one flange protruding laterally from the anchor rail is formed on the retaining bracket; a flange is preferably provided on each opposite side. Each flange is connected via a predetermined breaking point with a central section of the retaining bracket a related party.
  • This enables the anchor rail to be fixed using fixing elements, such as nails or staples, which are introduced into the flange.
  • the flange can then be removed from the anchor rail together with the fixing element, so that no fixing elements remain on the building body made of concrete.
  • the flanges can be separated from the central portion of the bracket.
  • the resulting recess in the concrete body by removing the flange is negligible with regard to the holding forces of the anchor rail and the visual impairment.
  • the flange can for example have a thickness of less than 5 mm, preferably between 1 mm to 4 mm, so that it can be easily penetrated and the im Concrete recess remaining by removing the flange is small.
  • the size of each flange can be, for example, between 1 cm 2 to 4 cm 2 and is therefore easy to meet during assembly.
  • folding brackets For easy assembly of the folding brackets, they can be attached to the anchor rail.
  • the folding brackets can be fixed to the anchor rail by clamping or locking.
  • a positioning aid for example a web or a projection, which engages in a receptacle or recess on the anchor rail in order to prevent displacement of the anchor rail in the longitudinal direction, can be provided on an inside of the retaining bracket.
  • Each anchor rail is preferably fixed to a formwork component by means of several retaining brackets.
  • the retaining bracket is preferably made of plastic Herge, but can also be made of other materials.
  • the anchoring element is preferably assembled into a unit before casting, in which the anchor rail is fixed to a plate-shaped formwork component via at least one retaining bracket.
  • the at least one retaining bracket is fixed to a protruding flange of the formwork component via at least one fixing element, preferably via a nail in each case.
  • Such a unit can also be produced in any length, with a retaining bracket being used to align two adjacent anchor rails, which extends over both anchor rails in the joint area. This allows the two anchor rails to be aligned using the retaining bracket.
  • an anchor rail is first positioned on a formwork component in order to then arrange at least one bracket over the anchor rail.
  • the retaining bracket is then fixed to the formwork component via at least one fixing element, in particular a nail, in order then to cast the anchor rail in concrete.
  • the formwork component with the at least one fixing element is then removed from the anchor rail.
  • the fixing element on the concrete structure can no longer pose a safety risk or lead to a visual impairment due to rust.
  • at least one flange of the retaining bracket with the fixing element is removed during removal, the flange being separated from a central section of the retaining bracket along a predetermined breaking point.
  • the fixing elements are designed as nails and are shot into the formwork component using a nail gun.
  • FIG. 1 shows a perspective view of an anchor rail with two retaining brackets and a formwork component
  • FIGS. 2A to 2D show several views of the anchor rail of FIG. 1 in an assembled position
  • FIGS. 3A to 3C show several views of the anchor rail of FIG. 1 after it has been removed from the formwork component
  • FIGS 4A to 4D several views of a retaining bracket for fixing the
  • FIG. 5 shows a perspective view during the assembly of two anchor rails on a formwork component.
  • An anchoring element for casting in concrete comprises an anchor rail 1 and at least one retaining bracket 20, by means of which the anchor rail 1 can be fixed to a formwork component 10.
  • the anchor rail 1 comprises a plurality of anchor webs 2 which protrude from a strip-shaped rail part with a receptacle for mounting fasteners supply means.
  • Each anchor bar 2 has a widened end section and is poured into concrete.
  • a shaped body 4 made of an elastic material is inserted into the receptacle of the rail part, which prevents concrete from penetrating into the receptacle.
  • the anchor rail 1 can be made from two rail parts which are fixed to one another via connecting webs 5. On the side facing the formwork component 10, a channel-shaped receptacle for fastening means, such as hammer head screws, can be formed.
  • the anchor rail 1 can be designed as is disclosed in document DE 102019 106 155.
  • the at least one retaining bracket 20 engages over the anchor rail 1 in a direction perpendicular to the longitudinal direction.
  • Each retaining bracket 20 has a middle bracket-shaped section 21 on which a flange 22 is formed on opposite sides.
  • the flange 22 can be connected to the formwork component 10 via a fixing element 11, such as a nail or a staple, in order to fix the anchor rail 1 indirectly via the retaining bracket 20 on the formwork component 10.
  • FIGS. 2A to 2D the anchor rail is shown in a position mounted on a formwork component 10.
  • Two retaining brackets 20 are mounted on the formwork component 10.

  • flanges 22 extend on both sides, which are essentially plate-shaped and are connected to the middle section 21 via a predetermined breaking point 24.
  • the predetermined breaking point 24 can be produced by weakening the material, that is to say by reducing the material cross section, for example by reducing the thickness or by a perforation, so that the flange 22 can be securely separated from the central section 21.
  • a reinforcement strut 25 is formed, which strengthens ver in the area adjacent to the predetermined breaking point 24.
