Definitions

  • the invention relates to a fastening element for the spacing of plates, profiles, slats or the like on a base, an adjustment part being coupled to a bolt which can be fixed on the base by means of a dowel, the adjustment part being infinitely adjustable in the direction of the longitudinal axis of the bolt via a threaded connection , and wherein the adjustment member carries a bracket to which the plate or the like can be attached.
  • Such a fastener is known from DE 32 32 105 A1.
  • a dowel is used, which in the usual way has a receptacle for a bolt designed as a screw.
  • the dowel has an external thread on its outer contour.
  • An adjustment part can be screwed onto this.

  • the setting part can be turned on the external thread of the dowel. This also sets the profile piece in the axial direction of the bolt.
  • the dowel must be adapted to the setting part, but this results in a complex manufacture for the dowel.
  • Another fastening element is known from DE 100 03 097 C2.
  • the fastening element has a bolt which can be screwed to a base, for example a wall, using a dowel. At its end facing away from the dowel, the bolt has a threaded section. After setting the bolt, an adjustment part can be screwed onto this.
  • the setting part takes a bracket axially immovable, but freely rotatable. As a result of a rotation of the adjustment part, a crossbar or the like coupled to the holder can thus be adjusted.
  • the production of the bolt is very complex. Furthermore, the mounting of the fastening element is not easy and can only be carried out using special tools.
  • the adjusting part is adjustable on a threaded section of a threaded sleeve, and in that the threaded sleeve is held by the bolt as a component separate from the dowel.
  • the adjusting part and the threaded sleeve form a functional unit.
  • Standard components can be used for the dowel. This can significantly reduce the amount of parts for the fastener. The amount of parts is also minimized if, for example, standard bolts are used for the bolt.
  • the dowel and the bolt can be dimensioned independently of the threaded sleeve and the setting part. This allows adaptation to different insulation structures of the sub-floor to be carried out with little effort.
  • the threaded sleeve is pushed onto the bolt with a base part having the threaded section, and that the base part has a connecting section which forms a rotationally fixed connection with the dowel when the bolt is in the assembled state.
  • the setting part can be easily fixed to the dowel without the need for additional parts.
  • the adjustment part is fixed with the aid of the bolt.
  • the connecting section of the base part has tooth-like projections and that the threaded sleeve consists of a harder material than the dowel.
  • the tooth-like projections dig into the softer material of the dowel, so that there is a positive connection in the circumferential direction of the bolt.
  • the threaded sleeve forms a stop which limits the screwing-in movement of the bolt into the dowel.
  • the dowel can be brought into its intended position.
  • the bolt can then be moved against the stop of the threaded sleeve. In this way, compliance with a predefined assembly sequence can be carried out.
  • the fact that the bolt against the stop of the If the threaded sleeve is driven, a certain distance ratio between the threaded sleeve and the substrate can also be maintained. Insulation can be fixed in this space or held with an insulation holder plate.
  • the adjustment part has a tool holder for an adjustment tool in the distance region between the base and the holder.
  • the adjusting part has a base body into which a receptacle is inserted, that the bolt passes through the receptacle, and that the receptacle has an extension in which the head of the bolt designed as a screw is received, then the bolt can be countersunk be included in the setting part.
  • a possible variant of the invention is characterized in that the holder has an open plug-in receptacle on a fastening section, by means of which the holder is plugged onto a holding receptacle of the adjusting part, that the holding receptacle secures the fastening section in the axial direction of the bolt and that the adjusting part is opposite the holder in the circumferential direction of the Bolt is freely rotatable.
  • the bracket can then be attached to an adjustment part already in the final assembly position. However, subsequent adjustment of the fastening element is still possible via the rotary bearing.
  • connection of panels for example facade cladding panels
  • the holder has a panel-like extension which is aligned perpendicular to the central longitudinal axis of the bolt and protrudes laterally beyond the adjusting part.
  • FIG. 1 shows a fastening arrangement with a fastening element in side view and in vertical section
  • FIG. 2a-2e an assembly sequence for attaching a wall covering to a substrate using the fastening element shown in FIG. 1.
  • Fig. 1 shows a base 10 on which insulation 1 1 is applied on the front.
  • the substrate 10 can be masonry, for example.
  • the insulation 1 1 is penetrated by a hole which opens into the underground 10.
  • a dowel 20 is inserted into the bore.
  • the dowel 20 is supported by a collar 21 on the front of the insulation 1 1. This also limits the insertion movement of the dowel 20.
  • a bolt 22 in the form of a fastening screw is screwed into the dowel 20.
  • the fastening screw spreads and braces the dowel 22 in the underground in a known manner.
  • a threaded sleeve 30 is pushed onto the shaft 24 of the bolt 22.
  • the threaded sleeve 30 is produced as an injection molded part and, following its sleeve-shaped base body, has a widened edge which is designed as a stop 32 for the head 23 of the bolt 22.
  • the threaded sleeve 30 is provided on its outer circumference with a threaded section 31. In the area of your the stop 32 remote end, the threaded sleeve 30 has a positive connection portion to the collar 21 or shaft of the dowel 20. Tooth-like projections, z. B. in the form of ribs which protrude in the direction of the collar 21 or the shaft of the dowel 20, increase the connecting forces between the threaded sleeve 30 and dowel 20th
  • An adjusting part 40 is screwed onto the threaded section 31 of the threaded sleeve 30.
  • the setting part 40 has a cylindrical base body 41, which has an attachment facing the insulation 11.
  • the approach is provided with the internal thread corresponding to the threaded section 31.
  • the extension forms a tool holder 44 on its outer contour.
  • the setting part 40 can be rotated with a tool.
  • the base body 41 surrounds a receptacle 42. This is penetrated by the bolt 22.
  • the inner geometry of the cylindrical receptacle 42 is adapted to the diameter of the stop 32 of the threaded sleeve 30. This results in a guide that improves the tilting stability of the adjustment part 40.
  • the receptacle 42 merges into an extension 45. In this, the head 23 of the bolt 22 can be picked up together with a tool, as will be explained later.
  • the setting part 40 has a holding receptacle 43 in the form of a circumferential groove.
  • the holder 50 engages in this groove with a fastening section 51.
  • the fastening section 51 has a fork-shaped, laterally open plug receptacle 57. This results in a bearing between the setting part 40 and the holder 50, which enables the setting part 40 to be freely rotated while at the same time axially fixing the holder 50.
