Definitions

  • the present invention relates to an anchor rail for fixing fasteners to a channel-shaped receptacle, with two strip-shaped webs between which a slot is formed for the passage of fasteners, and a plurality of anchor elements which are fixed or integrally formed on the two webs, each An anchor element forms a lateral wall of the channel-shaped receptacle with a portion adjacent to the web, and has an integrally formed anchor web, and a method of manufacturing an anchor rail.
  • DE 10 2019 106 155 A1 discloses an anchor rail for casting in concrete, which has a channel to which hammer head screws and other fastening means can be fixed.
  • the anchor rail has two rail parts, which have a bent edge with teeth at one end, to which the hammer head screws are fixed.
  • On the opposite side a large number of integrally formed anchor bars protrude.
  • the two rail parts are connected to one another via integrally formed connecting webs which are welded to one another. To produce these connecting bars, openings are cut out in the anchor bars, which reduces the maximum holding forces through the anchor bar.
  • a multiplicity of anchor elements are fixed or formed integrally on two webs which are arranged on both sides of a channel-shaped receptacle. At least two anchor elements arranged on opposite sides of the channel-shaped receptacle are connected to one another via a separately produced connecting element, which is fixed to the anchor elements in a materially bonded and/or non-positive manner. Via the materially and/or non-positively fixed connection element, the distance between the anchor elements and their position can be specified.
  • the anchor rail is fixed with high strength, so that it can also absorb high loads in the area of the anchor elements.
  • the individual anchor elements can be produced without larger openings or recesses, in particular there is no recess for an integrally formed connecting web, since the connecting element is manufactured separately and then mounted on two anchor elements.
  • Each anchor element of the anchor rail is preferably connected to an anchor element on the respective other strip-shaped web with a connecting element. This ensures high strength over the entire length of the anchor rail.
  • the connecting element is preferably designed as a pin, in particular as a metallic pin.
  • the pin can have a stepped end and can be inserted with a tapered end section into an opening in the anchor element. As a result, an exact distance between two anchor elements can be specified via the pin when the end section of the pin is inserted into an anchor element on opposite sides.
  • the pin can be cylindrical between the end sections, which simplifies assembly and enables centering.
  • the end sections are preferably also of cylindrical or frustoconical design and are inserted or driven into a circular opening on the anchor elements.
  • a front end of the pins can end essentially flush with a surface of an anchor element. As a result, the transition area between the end section and the anchor element can optionally be welded well.
  • each anchor element is welded to a strip-shaped web, a first portion of the webs projecting towards the slot between the two webs and a second portion projecting from the anchor element to the opposite side.
  • the web with the anchor element is T-shaped in the connection area, so that after casting in a cast material, the outwardly protruding web serves as a supporting web for stabilizing the inwardly protruding web.
  • deformation or pivoting of the anchor element can be limited or reduced by using the outwardly protruding section as a support web acts and forms a counter bearing. This significantly increases the load capacity of the anchor rail.
  • Each anchor element and preferably also each strip-shaped web is preferably made from sheet steel.
  • the material of a strip-shaped web can have greater strength and/or be thicker than the material of an anchor element.
  • the strip-shaped web can have a thickness of between 3 mm and 8 mm, while the anchor element has a thickness of between 2 mm and 5 mm.
  • the strip-shaped web is preferably at least 20% thicker and/or has a 20% higher strength than the material of the anchor element.
  • the strip-shaped web can have teeth on the side of the slot between the two webs in order to be able to fix the fasteners in the longitudinal direction of the anchor rail.
  • first two strip-shaped webs are produced, to which separate anchor elements are attached or integrally formed anchor elements are provided by bending over the two webs. Furthermore, separate connecting elements are produced, for example pins, before the connecting elements are fixed to two anchor elements in a non-positive and/or cohesive manner, with the two anchor elements each being fixed to one of the two strips. This enables the anchor bar to be efficiently manufactured with high strength.
  • each anchor element is welded to a strip-shaped web, the welding being butt-welded to an end face of the anchor element, so that a first portion of the web protrudes towards the slot between the webs and a second portion protrudes to the opposite side and can act as a support web .
  • the anchor elements and/or the webs can be made of sheet steel, for example, with the webs being cut out by laser cutting or other cutting methods.
  • the material of a strip-shaped web can have greater strength and/or be made thicker than a material of the anchor element in order to produce the anchor rail with high strength.
  • Figure 1 is a perspective view of an inventive
  • FIGS. 2A to 2C show several views of the anchor rail of FIG. 1;
  • FIG. 3 shows a sectional view through the anchor rail of FIG. 1;
  • FIG. 4 shows a detailed view of an anchor element of the anchor rail of FIG. 1, and
  • FIGS. 5A to 5C show several views of the anchor rail of FIG. 1 during manufacture.
  • An anchor rail 1 comprises two strip-shaped webs 2, in particular made of sheet steel, between which a slot 3 is formed for the passage of fastening means.
  • a multiplicity of anchor elements 4 are fixed, in particular welded, to each web 2 .
  • the anchor elements 4 can be manufactured individually, or units made up of several anchor elements 4 can be connected to form a strip of anchor elements.
  • Two anchor elements 4 each arranged on opposite sides of the slot 3 are each fixed to one another via a connecting element 10 .
  • the anchor rail 1 can have any length, for example between 0.1 m to 6 m, in particular 0.5 m to 2 m, the number of anchor elements 4 per web 2 being between 2 and 120, in particular 4 to 50, for example.
  • the anchor rail 1 is designed symmetrically to a central plane parallel to the longitudinal direction, as can be seen in FIG. 2C.
  • Each anchor element 4 comprises a section 5 adjacent to the web 2 , which is aligned parallel to the section 5 of a section 5 fixed to the web 2 lying opposite.
  • a connecting element 10 is fixed to these two parallel sections 5 so that a channel-shaped receptacle is formed, which is delimited by the webs 2 , the sections 5 adjacent to the web 2 , and the connecting elements 10 . Heads of fasteners, for example hammer head screws, can be inserted into this channel-shaped receptacle 9 .
  • Each anchor element 4 comprises, integral with the section 5, an anchor web 6 which is essentially in the form of a strip, and a widened anchor 7 which is cast in concrete, in particular behind a reinforcement.
  • a kink 8 is formed between the anchor bar 6 and the section 5, so that the anchor bar 6 is aligned at an angle to the section 5, for example at an angle of between 5° and 90°, in particular 10° and 25°. The angle depends on the design of the concrete component, in particular whether there is sufficient space for accommodating the anchor webs 6 due to the thickness or width of the concrete component.
  • the kink 8 can also be dispensed with.
  • FIG. 10 A section through the anchor rail 1 in the area of a connecting element 10 is shown in FIG.
  • the connecting element 10 is designed as a pin, in particular as a cylindrical pin which has a tapered cylindrical end section 11 on opposite sides.
  • the distance between the two sections 5 of the anchor elements 4 is predetermined.
  • the axial length of the end sections 11 essentially corresponds to the thickness of the anchor elements 4.
  • the section 5 of the anchor elements 4 is butt-welded to one of the webs 2 on one end face.
  • the section 5 is welded in a central region of the web 2 so that, starting from the section 5, a section 2a protruding inwards towards the slot 3 and a section 2b protruding outwards are provided.
  • the outwardly protruding section 2b acts as a support web which, in the event of a tensile load on section 2a, provides support on the cast material after the anchor rail has been cast by means of a fastening means. This reduces pivoting of the section 5 of the anchor element, which is held by the anchor 7 under a tensile load.
  • the protruding sections 2a and 2b can, for example, have a length perpendicular to the longitudinal direction of the anchor rail 1 of between 2 mm and 8 mm.
  • the material of the strip-shaped webs 2 can be thicker or have a higher strength than the anchor elements 4. This ensures high holding forces with an effective use of material for the anchor rail 1.
  • the webs 2 have a toothing 12 on the side facing the slot 3 so that fastening means can be fixed in the axial direction of the anchor rail 1 via the toothing 12 .
  • An anchor element 4 is shown in detail in FIG.
  • the anchor element 4 is cut out of sheet steel and comprises a section 5 which is wider than the strip-shaped anchor bar which is connected to the section 5 via the bend 8 .
  • the widening anchor 7 is formed integrally on the anchor web.
  • An opening 14 is recessed in the section 5, which opening can have a smaller diameter than the end section 11 of the connecting element 10, so that the end section 11 is fixed in a clamping manner when it is inserted into the opening 14 by pressing.
  • the end section 11 can also be inserted into the opening 14 in an essentially form-fitting manner in order to then be welded to the anchor element 4 .
  • end section 11 it is possible to make the end section 11 longer than the thickness of the anchor element 4 and to let it protrude over the anchor element 4, so that the protruding section can then be pressed and the pressed end rests on the outside of the opening 14 on the anchor web 4 .
  • FIGS. 5A to 5C The manufacture of the anchor rail 1 is shown in FIGS. 5A to 5C.
  • a web 2 in the form of a strip is cut out of sheet steel, in order then to fix individual anchor elements 4 to the web 2 .
  • an end face 13 of an anchor element 4 is placed in a central region of the web 2 and welded, so that adjacent anchor elements 4 are welded to the web 2 along a line parallel to the longitudinal direction.
  • the anchor elements 4 can rest against one another at the ends or be arranged at a distance.
  • connecting elements with a different geometry can also be used, in particular pins or brackets.
