Definitions

  • the invention relates to a fastening element for fastening a roofing membrane on a Insulation on a flat roof with the features of the preamble of claim 1.
  • Such a fastener is known from the German patent application 26 17 911.
  • the known fastener has a perforated disc, one of which Protrudes hollow shaft. There is a hollow hollow shaft through the hole in the blade accessible.
  • the fastener is with its hollow shaft through a roofing membrane inserted, which rests on insulation such as mineral wool.
  • the roofing membrane is, for example, a plastic film or tar paper that covers the flat roof waterproof seals.
  • Before inserting the hollow shaft there may have to be a hole be installed in the roofing membrane.
  • the fastener is with his Hollow shaft inserted through the roofing membrane into the insulation so that the washer on the Roof membrane is on.
  • For fastening on the flat roof is a screw, a nail or the like.
  • Element inserted into the hollow shaft, from an end distal to the disc protrudes from the hollow shaft and so into a dowel inserted into the flat roof the metal support lying on the flat roof or a support lying on the flat roof Wood substructure or the like can be screwed in.
  • the known fastener has the disadvantage that its clamping effect on the roofing membrane is low. Thanks to wind-reduced tensile forces acting on the roofing membrane can the roofing membrane from a push-through point of the hollow shaft of the fastener starting to tear down and shift. The result is a leak in the roofing membrane.
  • the invention is based on the object of a fastening element for fastening to propose a roofing membrane on an insulation on a flat roof that has a higher Holding value for the roofing membrane.
  • the Disc of the fastener according to the invention has claw elements that press into the roofing membrane when pressing on the pane.
  • the claw elements can for example be designed as teeth or serrations. They are trained that they penetrate the roofing membrane but do not penetrate it.
  • the claw elements pressed into the roofing membrane create a positive connection between the roofing membrane and the washer of the fastener that hold the roofing membrane improved on the disc of the fastener. This avoids that the roofing membrane moves against the pane of the fastener and on the insertion point of the hollow shaft of the fastener tears.
  • the fastener is under load can move axially on the screw with its hollow shaft. Will be at Walking on the flat roof on the fastener, the insulation compressed and the fastener lowers together with the roofing membrane. The fastener does not stand up from the roofing membrane in front, whereby a risk of injury is avoided. At the same time Damage to the roofing membrane avoided, since the fastening element with the roofing membrane with moves. This is indicated by air in the hollow shaft Fastening element according to the invention has an insulating effect, a cold bridge avoided. Due to the hollow shaft, a short and therefore inexpensive is sufficient Screw or the like. For fastening the fastener on the flat roof. Another advantage is that the screw or the like is less susceptible to corrosion since a head of the screw is not in the area of a due to its recessed position in the hollow shaft Dew point.
  • the fastening of the fastening element to the flat roof can, as already mentioned by screwing a screw inserted into the hollow shaft into a sheet metal support or in a wooden substructure on the flat roof.
  • a screw inserted into the hollow shaft into a sheet metal support or in a wooden substructure on the flat roof.
  • the Hollow shaft inserted nail driven into such a wooden substructure become.
  • the screw is screwed into a dowel, which is inserted in a hole in the flat roof.
  • the hollow shaft of the fastener be provided in one piece extending dowels, in one Screwed in or in for spreading and anchoring the anchor in the flat roof Nail or other expansion element can be driven.
  • the hollow shaft of the fastener according to the invention can be made in one piece with the the disc having claw elements.
  • the hollow shaft has a head under which the claw elements have Washer is arranged in the manner of a washer.
  • the disc can be made of sheet metal, i.e. H. made of a rigid material his.
  • the hollow shaft with the head can be used to achieve a good insulation effect Plastic.
  • the disk has Invention a stiffener.
  • the stiffening can be radial, for example or circumferential beads.
  • the fastening element 10 has a blade 12 and a hollow shaft 14 with a head 16.
  • the hollow shaft 14 is made in one piece with the head 16 from plastic, for example by injection molding.
  • the disc 12 is made of sheet metal.
  • the hollow shaft 14 is tubular and tapers an end 18 distal to the head 16 in the shape of a truncated cone.
  • the frustoconical end 18 has a hole for the exit of a screw 20.
  • the head 16 of the hollow shaft 14 has the shape of a radially projecting flange.
  • a cavity 22 of the Hollow shaft 14 passes through the head 16 as a central hole, so that the screw 20 can be inserted into the hollow shaft 14 through the hole in the head 16.
  • the disc 12 is a perforated disc with a central hole 24 for inserting the hollow shaft 14 trained.
  • the disc 12 has a concentrically rotating one Bead 26 on which when the shaft 12 is inserted through the disc 12 Head 16 of the hollow shaft 14 surrounds ( Figure 2).
  • An edge 28 of the disc 12 is oblique bent at an angle of about 45 ° to the disk 12.
  • the edge 28 is with the outside open, radially extending slots 30, edges of the slots 30 are bent into jagged claw elements 32.
  • the hollow shaft 14 is through the center hole 24 of the disc 12 inserted, so that the head 16 of the hollow shaft 14 on the Disc 12 is present.
  • the screw 20 is through the head 16 of the hollow shaft 14 introduced into the cavity 22 of the hollow shaft 14, so that its threaded shaft on tapered end 18 emerges from the hollow shaft 14.
  • the disc 12 is oriented that the bead 26 and the inclined edge 28 on one of the tapered end 18 of the Hollow shaft 14 facing away from the disc 12.
  • the claw elements 32 project from the disk 12 in the same direction as the hollow shaft 14.
  • the fastening element 10 is as shown in FIG. 3 for fastening a roofing membrane 34 is provided on insulation 36 on a flat roof 38.
  • the screw 20 has a drill tip 33. With the help of an electrical or pneumatic screwdriver, which is non-rotatably engaged with the screw 20, the Screw 20 and together with it the fastener 10 is rotated. With the drill tip 33 of the screw 20, the roofing membrane 34 is pierced and the insulation 36 pierce.
  • the insulation 36 is, for example, a mineral wool.
  • the Drill tip 33 of screw 20 is drilled through a trapezoidal sheet 40, for example rests on the flat roof 38 and is fastened thereon.
  • the trapezoidal sheet 40 has trapezoidal stiffeners in cross section.
  • the screw 20, which is a self-tapping Has thread is screwed into the trapezoidal sheet 40, where that Fastening element 10 is attached to the flat roof 38.
  • the screw 20 is screwed into the trapezoidal sheet 40 until the Disk 12 of the fastener 10 rests on the roofing membrane 34 with pressure.
  • the Claw elements 32 press into the roofing membrane 34 without the roofing membrane 34 punctured.
  • the disc 12 resting on the roof membrane 34 with pressure causes one Clamping force that holds the roofing membrane 34.
  • the claw elements pressed into the roofing membrane 34 32 of the disc 12 cause a form fit between the disc 12 and the roofing membrane 34, which improves the hold of the roofing membrane 34.
