  • these two components can be chemically welded, for example by means of a swelling agent such as tetrahydrofuran.
  • the disk-shaped film section can be welded absolutely tightly to the continuous sealing layer by means of hot-air welding or a joining substance.
  • the fastening anchor formed according to the invention there is an absolutely tight connection between a respective substrate, concrete or rock and the sealing layer, or the concrete layer arranged underneath.
  • the fastening anchor shown in FIG. 1 has a sealing body 1 which contains a disk-shaped film section 2.

  • the film section 2 is formed integrally with the sleeve section 4.
  • a threaded rod 5 extends through the sleeve portion 4, the passage opening 3 and the disc-shaped film section. 2
  • the threaded rod 5 is materially connected to the sleeve portion 4.
  • the disk-shaped film section 2 (and obviously also the sleeve section) consists of a material which can be materially connected to the sealing layer 6 to be described later.
  • the disc-shaped film section 2 and the sealing layer 6 may consist of materials which can be welded together, advantageously of the same materials.
  • connection between the disk-shaped film section 2 and the sealing layer 6 can be produced by means of a hot-air welding.
  • a chemical welding by means of, for example, a swelling agent or also a compound by means of an adhesive may be used.
  • hot air welding is preferred.
  • sealing strips 6 preferably consist of a soft plastic, in particular soft PVC.
  • the sealing body 1 with the film section 3 and the sleeve section 4 likewise preferably consists of a soft plastic, in particular soft PVC.
  • the threaded rod 5 consists of three sections.
  • the first portion is a screw threaded portion 7 for receiving nuts 8,9. Obviously, there may be only one nut for other applications. For the sake of good order, washers 12,13 are shown.
  • This screw thread section 7 is followed by a connecting section 10, which has an at least approximately uniform, advantageously smooth surface.
  • This connection section 10 is in turn followed by an anchoring section 11.
  • This anchoring section 11 has a structured surface for anchoring in a respective substrate, for example by means of an adhesive mortar.
  • This surface-structured anchoring portion 11 is formed as a screw thread, wherein this screw thread is formed equal to that of the screw threaded portion 7, whereby a particularly cost-effective production of the threaded rod 5 is reached.
  • These screw threads can be, for example, M16 or M20 threads.
  • the sealing body 1 consisting of the disk-shaped film section 2 and the sleeve section 4 consists of a soft plastic, preferably soft PVC
  • the threaded rod 5 consists of a hard plastic, preferably hard PVC.
  • the threaded rod 5 extends through the sleeve portion 4, to emerge at the through hole 3 from the disc-shaped film section 2.

  • a source of welding agent for example, tetrahydrophorane or equivalent substance applied to the connecting portion 10 and optionally on the inner wall of the sleeve portion 4, the threaded rod 5 is pushed into the sleeve portion 4, whereby these two sections 4 and 10 materially and thus absolutely tightly connect with each other.
  • This joining method is particularly advantageous in the case of PVC for threaded rod 5 and sleeve section 4.
  • This welded region of the sections 4 and 10 is indicated by the thick bar with the reference numeral 14.
  • the sleeve section 4 may also be bell-shaped in the lower third of its longitudinal extension and may be connected to the threaded rod 5 only at the upper two-thirds of its longitudinal extent, so that a certain pivoting movement of the threaded rod 5 relative to the disk-shaped film section is possible.
  • FIG 2 relates to the use of the fastening anchor in a building, e.g. in a high-rise, in which as an example a suspended ceiling (in Figure 2 reference numeral 15) and a sealing layer 6 in the form of plastic sheets between the suspended ceiling 15 and the base material 16, here the concrete forming the substrate, wherein the reinforcement is not shown, is available.
  • a suspended ceiling in Figure 2 reference numeral 15
  • a sealing layer 6 in the form of plastic sheets between the suspended ceiling 15 and the base material 16, here the concrete forming the substrate, wherein the reinforcement is not shown, is available.
  • FIG. 1 Another variant for a building sees the fastening anchor for anchoring, for example, masts to e.g. Buildings in front.
  • the drawing sheet of Figure 2 must be turned upside down, in which case the anchoring portion 11 penetrates downwardly into the ceiling of the building (base material 16), the plastic sheet or sealing layer 6 is sealingly applied to the ceiling and e.g. Mast feet with the thread shown in Figure 2, i. Screw threaded portion 7 are screwed.
  • a hole 17 in the concrete 16 is formed wherever a fastening anchor is to be used.
  • the waterproofing membrane 6 of eg soft PVC on the concrete 16 layer.
  • Such sealing sheets are well known and are generally used as surface seals and thus need not be described in detail.
  • the sealing sheet 6 is cut, for example, two cuts are made in the form of a cross. If the bore 17 is made only after the attachment of the sealing strip 6, a penetration of the sealing strip 6 is already present here.
  • a curing bonding agent is introduced, for example, epoxy resin mortar.
  • the anchoring portion 11 can be inserted into the bore 17, wherein the penetration depth of the anchoring portion 11 is determined in the bore 11 by the abutment of the disc-shaped film section 2 on the sealing film 6.
  • the epoxy resin mortar results in a firm connection between the anchoring portion 11 and the wall of the bore 17th
  • the disk-shaped film section 2 consists of the same plastic from which the sealing strip 6 consists.
  • the welding can e.g. be a hot air welding. As a result of this welding, a cohesive connection is produced between the disk-shaped film section 2 and the sealing web 6, with the result that an absolutely tight connection is produced.
  • a reinforcement plate 18 are arranged, which is locked by the nuts 8, 9 on the screw threaded portion 7 of the threaded rod 5.
  • the reinforcement is attached, for example here a reinforcing mesh 20.
  • other objects may be connected to the screw threaded portion 7, such as lighting fixtures, electrical installations and other useful for the operation of a building apparatus and equipment.

  • a sealing, hardenable plastic can be applied in the flowable state.
  • FIG. 3 shows an embodiment in which the lining is shown in underground mining with the aid of the fastening anchor described. The following description is based on that of Figure 2, and accordingly, only the differences from the embodiment of Figure 2 will be discussed.
  • the reference numeral 21 designates the rock, the rock used to construct e.g. a tunnel is pierced. On this rock 21 a first layer of concrete 16 is applied, e.g. in a known manner shotcrete. For reasons of clarity, the rebars that are obviously present here are not drawn again.
  • the holes 17 are formed by this first layer of concrete 16.
  • the respective bore 17 can now extend into the concrete layer or even completely through them up into the rock 21 up.
  • the sealing layer 6, for example, flowable plastic or a waterproofing membrane made of soft PVC, for example, is applied to the side of the first layer of concrete 16 facing the erupted space.
  • the insertion of the anchoring, the tight connection between the disc-shaped foil section 2 and the exemplary sealing strip 6 and finally the placement of the second layer of concrete 15 here takes place according to the embodiment according to FIG. 2.
