Definitions

  • the invention relates to a fastening element for fastening insulation boards to components, with a sleeve-shaped holding part having a head plate and a fastener according to the preamble of claim 1.
  • Such a fastening element is known from WO-A-9 101 420, the depth of penetration of the fastener in a predrilled component being fixed with the aid of a stop collar seated on the surface of the component, and the space available for the insulation boards between the head plate and the Top of the component can be adjusted both during assembly and subsequently by shortening the distance between the top plate and the top of the component. to adjust the adapter sleeve is moved in the direction of impact of the fastener along the shaft of the fastener according to the required adjustment.
  • EP-0 420 799 discloses a fastening element with a sleeve-shaped holding part having a head plate, which can be clamped against the component by means of a nail for holding the insulation board.
  • the length of the holding part corresponds exactly to the thickness of the insulation board, so that the end face of the holding part sits on the component when the nail is driven in.
  • the invention has for its object to provide a fastener for attaching insulation panels to components that largely unaffected by unevenness of the component surface or the penetration depth of the nails ensures a uniform tensioning of the holding part and thus the insulation board.
  • the nail driven into the anchoring base for example by means of compressed air-operated setting tools, generates the nail in the inner bore of the Holding part supported clamping sleeve a tensile force acting on the holding part and thus on the head plate in the direction of the component, which leads to a tension of the holding part and thus the insulation plate.
  • the friction of the nail in the clamping sleeve is set so that the insulation board is clamped sufficiently against the component without immersing the head plate.
  • the depth of penetration of the nail into the anchoring base largely depends on the strength of the anchoring base.
  • the tensioning of the insulation board is determined by the friction of the nail in the adapter sleeve regardless of the penetration depth of the nail.
  • the entire length of the nail shaft there is a possibility of compensating for unevenness or different penetration depth of the nail with constant tension acting on the insulation board.
  • Either a closed sleeve with a slightly smaller inner diameter than the outer diameter of the nail shaft or a spring sleeve provided with a longitudinal slot can be used as the clamping sleeve.
  • the length of the holding part is somewhat less than the thickness of the insulation plate to be fastened.
  • the clamping of the adapter sleeve on the nail shank can result in the head plate being pulled against the component until the end face of the holding part lies against the component surface.
  • the holding part limits the distance of the head plate from the surface of the component. Due to the very soft insulation board, the edges of the head plate do not bulge in these cases, but only a somewhat stronger compression of the insulation board in the area of the fastening element.
  • the clamping sleeve can be supported in the holding part in that the holding part has an enlarged first section starting from the top plate and then a second section, the diameter of which is approximately equal to the diameter of the nail shaft reduced to form a stop shoulder.
  • the clamping sleeve is now arranged on the nail shaft in such a way that it can be supported on this stop shoulder. It is expedient to arrange a metal disc on the stop shoulder.
  • the clamping sleeve is locked in the inner bore of the holding part. This can be done in such a way that either the clamping sleeve is molded around as an insert during the injection molding process of the holding part or by inserting the clamping sleeve in an expansion of the inner bore of the holding part. In this case it is advisable to close the extension with a cover cap and thus fix the clamping sleeve in the sleeve part so that it cannot move in both directions.
  • the clamping sleeve can also be locked in the sleeve part by means of projections and / or flanges of the clamping sleeve which engage in the sleeve part.
  • the fastening element 1 shown in FIG. 1 consists of a sleeve-shaped holding part 2, on the end of which a head plate 3 is integrally formed and protrudes radially.
  • the inner bore 4 of the holding part has an enlarged first section 4a, which is followed by a second section 4b with the formation of a stop shoulder 5, the diameter of which is reduced approximately to the shaft diameter of the nail 6.
  • the nail is held in the sleeve part by means of ribs or a correspondingly adapted diameter of section 4b.
  • a clamping sleeve 7 is slid onto the nail shaft and is supported with its lower edge over the metal disk 8 on the stop shoulder 5 of the sleeve part.
  • the clamping sleeve 7 is formed with a continuous longitudinal slot 9 as a spring sleeve, so that the friction of the nail in the clamping sleeve can be determined via the elasticity of the spring sleeve.
  • the fastening element 1 is pressed in through the insulation board 10 until the head plate 3 rests on the outer surface of the insulation board 10.
  • pre-drilling may be required to insert the holding part.
  • the nail 6 is now driven into the component 11 by means of a setting tool operated, for example, by compressed air (see FIG. 2).
  • the friction of the nail 6 in the clamping sleeve 7 creates a tensile force during the driving-in process, which leads to the insulation board 10 being braced by means of the head plate 3.
  • the nail 6 moves relative to the adapter sleeve and penetrates into the component 11.
  • the penetration depth depends, among other things, on the strength of the component 11 on the one hand and on the clamping of the clamping sleeve 7 on the nail shaft on the other hand. It is expedient that the length of the holding part 2 is somewhat less than the thickness of the insulating plate 10. In the case of the usual insulating plates, the axial displacement of the holding part 2 when the nail is driven in is limited by the head plate. In the case of insulation boards with very low compressive strength, the end face of the holding part 2 may sit on the component 11. This ensures that the distance of the head plate from the surface of the component always remains the same and at the same time a sufficient tensioning of very soft insulation boards is made possible.
  • a thin-walled protective cover 17 is arranged on the end face of the holding part 2. During the assembly process, this protective cover is compressed in accordance with the axial movement of the holding part 2, so that the nail shaft exposed between the holding part 2 and the component 11 is sealed.
  • the protective cover 17 is either integrally formed on the holding part 2 or attached as a separate part to the end face of the holding part 2.
  • the enlarged section 4a is either filled with a sealing compound or closed with a stopper 18 on the opening of the enlarged section 4a, as shown in FIG.
  • the clamping sleeve 7 is embedded in an extension 12 of the reduced diameter portion 4b of the holding part 2a. This is done by injection molding in such a way that the clamping sleeve 7 is inserted as an insert into the injection molding tool for the holding part 2a and overmolded.
  • the holding part 2b with the extension 12 for the clamping sleeve 7 is produced by the injection molding process.
  • the clamping sleeve 7 is then inserted into the extension 12 and the clamping sleeve is locked in the axial direction by pressing in the cover disk 13.
  • the clamping sleeve 14 is fixed in the holding part 2c via radially projecting projections 15 and additionally a collar-shaped flange 16.
  • the clamping sleeve 14 can be inserted either by extrusion coating with the holding part 2c or by an assembly process.
