Definitions

  • the invention relates to an anchor rail for construction technology with one rail part and at intervals from each other anchors attached to the rail part, whereby the anchors one anchor foot and one opposite the Have anchoring shank with a smaller cross-section, the anchors on the rail part in in the Holes made through the rail part through these are fixed, with the anchor foot inside the rail rests on the rail part and the anchor shaft one lying on the outside of the rail on the rail part Has captive security.
  • - anchor channels for the Construction technology is manufactured by the meter, with the Anchors can be detached or fixed, but cannot be lost with the Rail part are connected.
  • the rail part has in usually, but not mandatory, essentially one C- or U-shaped cross-section perpendicular to the longitudinal extension of the rail part.
  • the anchors are in this case usually connected to the back of the rail.
  • the both legs of the rail part leave a gap free, the width of which is such that an anchor foot can be passed through.
  • the anchor foot do not fit through the hole in the rail part may.
  • the diameter of the anchor shaft the anchor foot is the same or slightly smaller than the diameter of the hole in the rail part his.
  • the distances between two anchors are for example 250 mm.
  • Anchor channels of the structure mentioned at the beginning are, for example from references DE 25 31 396 C1 and EP 0 226 710 B1.
  • the anchor channels are fixed by that the anchor shaft with a fixed anchor base with a Clamping tool gripped at a distance from the rail part and moves it towards the anchor foot and thus a shaft part adjacent to the rail part is compressed becomes.
  • the result is the anchor on the one hand shortened and on the other hand by means of the outside of the rail attached, as it were squeezed material.
  • a structural change occurs during compression, in particular Microstructure compression.
  • These well-known anchor channels have several disadvantages. First of all it is complex to carry out a compression.
  • the invention is the technical problem to create an anchor rail, in which the anchors with less effort on the rail part are fixable and also the tensile strength of the anchor remains essentially unchanged or preserved.
  • a scraper collar is a loss protection, which by essentially cutting Material shaping is formed from the shaft.
  • the circumference of the shaft is by means of a Cutting tool a thin outer layer of the shaft peeled off towards the rail part, until at least part of the peeled off or stripped material on the outside of the rail comes to the concern.
  • the core of the shaft remains here practically unchanged, especially occurs practically no structural change.
  • the one stripping Scraper collar formed is of a comparative nature as such low strength, this strength is however, it is completely sufficient to protect against loss to fulfill.
  • the holes are convex on the outside of the rail Formations of the rail part arranged, preferably arranged concentrically to the formations.
  • the holes usually have in the rail part a substantially cylindrical cross section. Accordingly, the anchor shaft is orthogonal to Longitudinal extension of the anchor a circular cross-section, the diameter of the anchor shaft then to the anchor base preferably slightly is smaller than the diameter of the hole. Basically the invention is also for holes and anchor shafts with other cross sections, for example rectangular cross section, can be used.
  • the process of stripping can vary widely Ways take place as long as stripping continuously stripped or cut material or at least in the final phase of stripping stripped material not separated from the shaft core becomes. In any case, at least in the final phase of the Stripping so much material connected to the shaft core remain that a functioning as loss prevention Scraper collar connected to the shaft core remains.
  • the invention is characterized in that the Scraper collar from a before fixing the anchor compared to a second shaft part larger in diameter first shaft part of the anchor shaft is formed.
  • the first shaft part preferably closes immediately to the anchor foot. Then it needs Cutting tool only in the direction of the longitudinal extent the anchor shaft are moved, material from the the first shaft part is stripped.
  • the inside diameter of the cutting tool between the diameters of the first and second Part of the shaft. In this case, the cross sections the hole in the rail part and the first shaft part practically congruent.
  • the anchor typically has an anchor head.
  • the anchor head can be attached in a variety of ways his.
  • the second shaft part have an external thread on which one the anchor head forming nut is screwed on. Can too the anchor head is welded onto the second shaft part become.
  • the Anchor head from the second shaft part by means of wobble riveting is formed.
  • the striking tool is on the protruding from the rivet bed End of the shaft due to plastic material deformation an anchor head is formed.
  • the striking tool guides with one orthogonal to the shaft axis Level with an angle ⁇ 90 °, preferably between 1 ° and 20 °, most preferably 2 ° to 10 °, for example 5 °, angled striking surface a rotationally symmetrical Precession movement running to the shaft axis out.
  • the precession movement can additionally a rocking movement around a workpiece Swing axis be superimposed.
  • the cutting tool also the rivet bed at the same time Wear the anchor head.
  • the rivet bed lies then the cutting element in the axial direction of the anchor shaft across from.
  • Essential feature of wobble riveting is that the striking tool on a workpiece surface is passed on and practically no "smearing" of the material takes place.
  • the wobble riveting has the advantage that the required pressure forces or the opposite support staff compared to other techniques are considerably smaller. In this respect, both the Fixing the anchor as well as the design of the anchor head with relatively little elaborate design and operated devices.
  • the anchor foot carries a label. This is already before the anchor is fixed to the Rail part attached to the anchor and can be any Be kind; however, labeling is preferred to be embossed (raised or deepened). Such labels are mandatory. in the Within the scope of the invention it is possible to use the labeling on the anchor base during the manufacture of the anchor to attach, as the when stripping or if necessary wobble rivets forces occurring to support the Anchor feet are so small that the marking is not is destroyed, for example by equalization.
  • the Anchor foot can adjoin the perimeter on the strinside wear a support ring which is sufficient to prevent Pressure forces of processing when fixing and to pick up when tumbling. With such a ring even the most delicate markings in front of one Equalization or destruction protected.
  • the invention also teaches a method of manufacture an anchor rail, an anchor with an anchor foot and an anchor shaft from the inside of one Part of the rail with the anchor shaft through a hole in the rail part is inserted, the anchor foot on the inside of the rail against the rail part brought and held there, with the outside of the rail and spaced from the rail part
  • Anchor shaft comprehensive cutting tool set up is and wherein the cutting tool relative to the Anchor foot is moved towards the anchor foot and in the course of the movement of the anchor shaft, one on the outside of the rail wiper collar attached to the rail part forming, material is stripped.
  • the Anchor shaft can be orthogonal to its longitudinal extension have a circular cross section, the Anchor shaft adjoining the anchor foot and compared to a second shaft part larger in diameter has the first shaft part. After stripping the Scraper collar at the outside of the shin Anchoring can be done by wobble riveting an anchor head be shaped.
  • the holes 6 are protruding in a convex manner on the outside of the rail Formations 8 concentrically of the rail part 2 arranged.
  • the holes 6 in the rail part 2 have a substantially cylindrical cross section on.
  • the anchor shaft 5 points orthogonally to the longitudinal extent the armature 3 has a circular cross section on.
  • the scraper collar 7 is made before a fixation of the armature 3 relative to a second shaft part 9 diameter larger first shaft part 10 of the anchor shaft 5 formed (Fig. 1a-d).
  • the anchor head 11 is from the second shaft part 9 by way of wobble riveting molded (Fig. 2a-c).
  • the anchor 3 is from the inside a rail part 2 with the anchor shaft 5 by the Hole 6 inserted into the rail part 2 (Fig. 1a and 1b).
  • the anchor foot 4 is on the inside of the rail brought the rail part 2 into contact and held there. Outside of the rail and spaced from it Rail part 2 then becomes an anchor shaft 5 Cutting tool 12 with tool jaws 13 and in the cutting plates 14 mounted on the tool jaws 13 established (Fig. 1c).
  • the cutting plates 14 form essentially a circular opening, at whose the Anchor foot 5 facing edge cutting arranged are.
  • the cutting edges form a circle, the Diameter larger than the diameter of the second Shaft part 9, but smaller than the diameter of the first shaft part 10 (see also FIG. 3).
  • FIG. 2c A comparative view of Figures 2a-c is removable that after stripping the scraper 7 at your shank outside end of the anchor shaft 5 an anchor head 11 by means of wobble riveting is formed.
  • the second shaft part 9 of a tool which is preferably a coaxial concave to anchor shaft 5, for example bowl-shaped, rivet bed 15, collected and by means of a drive in the axial direction towards the rivet bed 15
  • Döpperwerkzeuges 16 is from the Rivet bed protruding shaft end due to plastic material deformation an anchor head 11 is formed.
  • the Döpperwerkmaschine 16 leads with one against one Shaft axis orthogonal plane with an angle of 15 ° angled striking surface 17 a rotationally symmetrical Precession movement running to the shaft axis out.
  • the figures also show that the cutting tool 12 also the rivet bed at the same time 15 for manufacturing the anchor head 11 carries.
