Definitions

  • the invention relates to a device for driving wedge dowels.
  • Wedge dowels are known. They have a shaft which is flattened on one side and has a holding disk arranged at the end. The flattened surface runs obliquely towards the free end of the shaft. A shaft-like wedge rests against this flattened portion, one end of which protrudes through an opening in the retaining disk. The free end of the shaft-like wedge rests on the flattening of the shaft connected to the retaining disk.
  • the transverse dimensions of the shaft-like wedge in the area with which it passes through the above-mentioned opening in the holding disc is dimensioned such that it is held in a force-locking manner in this opening.
  • Such wedge anchors are used used when mounting fittings are to be attached to a solid building ceiling, on which a suspended ceiling or a support grid for such a ceiling is to be mounted.
  • a hammer drill and a drill inserted therein, receiving holes are drilled in the massive ceiling.
  • These drills have a drill shank and a clamping shank, which is picked up by the hand drill.
  • An oblique shoulder is provided between the drill shaft and the clamping shaft, since the clamping shaft has a larger diameter than the drill shaft.
  • the wedge dowels which are connected to a holding fitting, are now inserted into the holes in the solid ceiling.
  • This holding fitting can consist of a perforated iron, an adjustable swing arm or a wire with an eyelet at the end.
  • the invention is characterized by a tubular one-sided closed sleeve, wherein the inner diameter of the cavity of the sleeve corresponds at least to the diameter of a drill shaft, which is used for drilling the receiving bore for the wedge dowel.
  • Expedient embodiments of the invention are set out in the subclaims.
  • the wedge dowel 1 shown in FIGS. 1 and 2 has a first shaft 2, which is firmly connected at the end to a retaining washer 3 or is integrally formed therewith.
  • This shaft 2 has a flattened portion 4 on the long side, which ends at a slope 5 against the free end of this shaft 2.
  • a flat, wedge-like second shaft 6 At this flattening 4 and the tapered bevel 5 is a flat, wedge-like second shaft 6, the lower end 7 is guided through an opening in the holding disc 3, so that this second wedge-like shaft 6 or its lower end 7 with respect to this holding disc 3 protrudes downwards.
  • This shaft 6 also has a shear zone 8 in its longitudinal central region.
  • this wedge dowel 1 is inserted into the bore 13, it is connected to an iron 14. Instead of such a perforated band iron or in addition to this, other holding fittings such as adjustable swing arm or wire bracket can be attached.
  • the wedge dowel inserted into the bore 13 - FIG. 3 - is held frictionally in the bore, but is not yet braced in the bore.
  • Fig. 5 now shows in vertical section a sleeve 15 which is made of hardened steel and which is closed on one side with a bottom 16.
  • a dent-like depression 17 is arranged in the center of the outside of this base 16.
  • This recess 17 can be designed as a flat spherical shell.
  • the axial length L of the inner cavity 18 of this sleeve 15 is greater than the axial length of the drill shaft 10.
  • the outer diameter D of the sleeve 15 corresponds approximately to the outer diameter of the clamping shaft 11 of the drill 9.
  • the inner diameter of the cavity 18 is somewhat larger than the diameter d of the drill shaft 10, so that this sleeve 15 can be plugged onto the drill shaft 10 without any particular effort.
  • the open end face of the sleeve 15 is slightly beveled, this bevel being designed to correspond to the oblique shoulder 19 of the clamping shank 11. With this beveled end face, the sleeve 15 then lies positively on the shoulder 19 of the drill 9.
  • the second shaft 6 of the wedge anchor 1 is now driven in and the wedge anchor 1 is clamped in the bore 13.
  • the sleeve 15 is pressed with the hammer drill switched on against the lower end 7 of the second shaft 6 of the wedge dowel 1, this lower end 7 being received by the dent-like depression 17.
  • This dent-like depression 17, which is expediently designed as a flat spherical shell, prevents the sleeve 15 from sliding sideways during operational use.
