Definitions

  • the invention relates to a suspension wire, which is designed at its upper end as part of a device for fastening to a bare ceiling.
  • Suspended ceilings suspended from a bare ceiling have different distances from the bare ceiling depending on the height of the rooms or the supply lines laid on the bare ceiling. Different suspension elements are used to bridge these distances. In the majority of all cases, however, directional suspension wires of 4 mm 0 are used.
  • Suspended wires of the aforementioned type are manufactured in different lengths. Its upper end is designed as part of a device for fastening to the bare ceiling: they have a hook, an eyelet lying in the plane of the hanging wire or an eyelet bent at right angles to the hanging wire. Quick-release clamps are pushed onto the middle parts of the directional suspension wires, which Hold the support rails of a ceiling structure and allow the ceiling structure to be adjusted - cf. e.g. DE 89 02 613 U1 -.
  • dowels are inserted into the raw ceiling, at the lower end of which an eyelet is screwed or punched out. The hook of the suspension wire is hooked into one of these eyelets.
  • suspension wires with eyelets When installing suspension wires with eyelets at the upper end, dowels are used that are mushroom-shaped at the lower end. As far as suspension wires with eyelets in their plane are concerned, they still have to be bent vertically. Since the suspension wire is notched when the eyelet is turned on, the notch can tear or even break when the eyelet is bent. The hooks on the suspension wires can stretch when loaded; the eyes open. In addition, two parts are always necessary for fastening the suspension wire to the bare ceiling, namely the dowel inserted into the bare ceiling and the suspension wire suspended from the dowel. In summary, the aforementioned attachment of the suspension wires is unsafe and complex.
  • the invention seeks to remedy this.
  • the invention has for its object to form a suspension wire at its upper end so that it can be introduced into the bare ceiling while avoiding a dowel and without having a hook or an eyelet.
  • this object is achieved solved that the upper end, which is formed on an elongated - linear - and unthreaded part - middle part - has a cross-section increasing towards the end face, which has a length at least on a diagonal that is greater than the diameter of the

  • the middle part 2 is selectable long.
  • Quick-release clamps, not shown, are attached to it, with the aid of which the height compensation between a bare ceiling and a false ceiling is carried out.
  • the suspension wire 1 has a cross section that increases toward the end face 4.
  • the cross-section has at the top end 3 at least on a diagonal a length which is greater than the diameter of the suspension wire 1. This diameter increases towards the free end.

  • the wedge 10 becomes to the end face 4 based on the diameter of the central part 2 of the suspension wire 1 on the one hand increasingly wider, on the other hand - in the view rotated by 90 - narrowingly narrower.
  • the upper end 3 is designed as a cone 11 that widens toward the end face 4.
  • the upper end 3 is designed as a nail head 12.
  • the expansion sleeve 6 bears on the surface 5 of the 5 upper end 3, which also surrounds the middle part 2 of the suspension wire 1.

  • the compression spring 17 is supported on the end face 18 of the expansion sleeve 6 facing away from the upper end 3.
  • Suspended wire 1 supported.
  • the support takes place here with the aid of two diametrically opposed cams 19 arranged on the suspension wire 1.
  • the upper end 3 of the suspension wire 1 is first inserted into the borehole without the expansion sleeve.
  • the expansion sleeve 6 is then pushed over the middle part 2 to the upper end 3 and into the borehole. There, the expansion sleeve is driven into the borehole with the help of a set iron.
  • a wedge sleeve 13 is supported on the nail head 12.
  • the insertion of the nail head 12 with the wedge sleeve 13, which together form a cone, is also carried out with the aid of a setting iron.
  • the suspension wire 1 is provided with two mutually parallel surfaces 21 at the transition between the upper end 3 / the wedge 10 and the middle part 2. Each surface 21 runs in the extension of one of the wide sides of the wedge 10.

  • the expansion sleeve 6 has a continuous longitudinal slot 23. However, this is now so wide that the expansion sleeve 6 can be placed around the suspension wire 1 and does not have to be pushed on in the axial direction. This makes it possible to request a hook or the like at the lower end of the suspension wire 1 before the expansion sleeve is applied. Approximately halfway up two claws 24 are provided.
  • Each claw 24 is created by a transverse slot starting from the edge of the longitudinal slot 23 and bending of the cut corner.
  • recesses 25 are provided in the expansion sleeve 6.

  • the expansion sleeve 6 can be introduced into the borehole in a controlled manner: it is fixed in a correct position on the lateral recesses 25, the part pressed flat as a result of the parallel surfaces 21, and the longitudinal slot 23.
  • the expansion sleeve 6 like the expansion sleeve shown in FIGS. 7 and 8, has the slot 23 running in the longitudinal direction. This, in turn, is so wide that the expansion sleeve 6 can be placed around the suspension wire 1 and does not have to be pushed on in the axial direction. This makes it possible to form a hook or the like on the lower end of the suspension wire 1 before the expansion sleeve is applied.
