Definitions

  • the present invention relates to a fastening anchor for tightly anchoring an object in a stone substrate, a continuous sealing layer being arranged between the object to be anchored and the stone substrate. It also relates to a lining of ceilings and walls of buildings, which lining has a continuous sealing layer acting as a surface seal, on which a layer of concrete is arranged and with a plurality of fastening anchors designed according to the invention for the layer of concrete.
  • the basic material of the building When lining ceilings and walls of buildings, e.g. made of concrete, the basic material of the building applied a sealing layer, which e.g. is applied in a flowable state and then hardens or has the form of plastic sheets. A layer of reinforced concrete is applied to this sealing layer. This layer of concrete must obviously be anchored and for this purpose fastening anchors are used, which are anchored in the basic material of the building. It is now evident that these fastening anchors penetrate the sealing layer, which means that the sealing is interrupted.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of providing a fastening anchor for the tight connection of an object in a stone substrate, in which a plate section is integrally connected to a pin section to be inserted into the stone substrate, in which pin section a blind hole extending from the plate section is formed, which plate section is connected on its side facing away from the pin section with a disk-shaped film part, the diameter of which is larger than the diameter of the plate section and is connected with a continuous sealing layer can be welded integrally, a threaded rod intended for connection to the object to be carried being screwed into the blind hole.
  • the lining of ceilings and walls of buildings equipped with such fastening anchors which lining has a continuous sealing layer acting as a surface seal, on which a layer of concrete is arranged, the fastening anchors projecting into the basic material of the building is characterized in that the peg section of the respective beams runs through the sealing layer and is inserted in a hole in the base material of the building and is locked therein by means of a connecting material, preferably adhesive mortar, the plate section resting on a side region of the sealing layer facing away from the base material and being tightly connected to it, and that section of the threaded rod protruding from the blind hole is embedded in the layer of concrete and carries at least two nuts, which are used, for example, to support a reinforcement plate, such that a penetration-free anchor fastening Arrangement for the surface seal is present, in which the threaded rod corrosion-encasing pin portion as a seal and at the same time as a force-transmitting body between the Basic material of the building and the threaded rod bearing the layer of
  • the lining of ceilings and walls made of rock in underground construction equipped with such fastening anchors which lining has a first layer of concrete applied to the rock, which is separated from a second layer of concrete by a continuous sealing layer acting as a surface seal, the fastening anchors being in the second layer
  • Protruding concrete is characterized in that the peg section of the respective carrier runs through the sealing layer and is inserted in a hole penetrating at least the first layer and possibly continuing into the rock and is locked in the same by means of a connecting material, preferably adhesive mortar, the plate section bears on a side region of the sealing layer facing the space broken out in the rock, and the disk-shaped film part in its outer section e projecting in a radial manner over the plate section in the radial direction if necessary, it bears against a side region of the sealing layer facing the space broken out in the rock and is tightly connected to it, and that the section of the threaded rod protruding from the blind hole is embedded in the second layer of concrete and carries at
  • the continuous sealing layer usually consists of a flowable plastic or of sheets of soft PVC or another plastic. Accordingly, that from the pin section and plate section existing carrier advantageously consist of hard PVC or another plastic and the disc-shaped film part made of soft PVC or another plastic.
  • the plate section of the carrier can thus be connected to the disk-shaped film part by hot air welding or a connecting material, which disk-shaped film part in turn can be welded absolutely tightly by hot air welding or with a connecting material to the continuous sealing sheet or layer.
  • the fastening anchor has a one-piece carrier made of plastic, preferably hard PVC in this exemplary embodiment, which is formed from a plate section 1 and a pin section 2 protruding therefrom.
  • the spigot section can be made of hard PVC and the plate section thus formed in one piece from soft PVC.
  • the outer wall 10 of the pin section 2 is structured in the form of a coarse thread. This results in extremely high pull-out forces of the pin section 2 inserted in a bore. This structuring of the outer wall 10 of the pin section 2 could, for example, take the form of a coarse screw thread.
  • a blind hole 3 is formed, which is equipped with an internal thread. A threaded rod 6 with a screw thread 7 is screwed into this blind hole 2.
  • the carrier is tightly connected to a plate-shaped film part 4 in the plate section 1.
  • This disk-shaped film part 4 consists of soft PVC, which material is here the same as that of the sealing layer or sealing membrane, with which, as will be shown below, the fastening anchor has a sealing effect.
  • the plate section 1 of the carrier is welded to the disk-shaped film part 4 by means of hot air welding, so that there is no space at any point between the plate section 1 and this film part 4. This means that the entire surface area, see FIG. 1, over which the plate section 1 rests on the film part 4 is welded, so that there is absolute tightness, since the plate section 1 and the disk-shaped film part 4 are in one piece at this point.
  • a suitable connecting material can be used to connect the plate section 1 to the film part 4.
  • a nut 8 is further screwed onto the threaded rod 6, which is made of a suitable metal or steel.
  • This nut 8 serves as a locking nut for a reinforcement to be described.
  • a washer 16 is also shown purely for example.
  • other structural arrangements made of metal and / or plastic can be used instead of the locking nuts 8 and 9.
  • FIG. 2 relates to the use of the fastening anchor in a building, for example in a building construction, in which, for example, a suspended ceiling (reference number 13 in FIG. 2) and a sealing layer 5 in the form of plastic sheets between the suspended ceiling 13 and the Base material 18, here concrete, with the reinforcement not shown, is present.
  • a suspended ceiling reference number 13 in FIG. 2
  • a sealing layer 5 in the form of plastic sheets between the suspended ceiling 13 and the Base material 18, here concrete, with the reinforcement not shown, is present.
  • FIG. 2 Another variant for a building sees the fastening anchors for anchoring, for example, masts on e.g. Buildings.
  • the drawing sheet of FIG. 2 must be turned upside down, in which case the peg section 2 penetrates into the ceiling (base material 18), the plastic sheet or sealing layer 5 is sealingly applied to the ceiling and e.g. Mast feet are screwed with the thread shown in the figure.
  • a hole 14 is formed in the concrete 18 wherever a fastening anchor is to be used.
  • the sealing membrane 5 from e.g. Soft PVC applied to the first layer of 12 concrete.
  • Such waterproofing membranes are generally known and are generally used as surface seals and therefore do not have to be described in more detail.
  • the sealing membrane 5 is cut through in each bore 14, e.g. two cuts are made in the shape of a cross. If the bore 14 is only made after the sealing membrane 5 has been applied, there is already a penetration of the sealing membrane 5 here.
  • a hardening connecting means is now introduced into the bore 14 produced, e.g. Epoxy resin mortar.
  • the pin section 2 can then be inserted into the bore 14, the depth of penetration of the pin section 2 into the bore 14 being determined by the abutment of the plate section 1 on the sealing film 5.
  • the epoxy resin mortar results in a firm connection between the peg section 2 and the wall of the bore 14.
  • the disk-shaped film part 4 is welded to the underside of the sealing membrane 5 at its peripheral area outside the plate section 1.
  • the disk-shaped film part 4 consists of the same plastic from which the sealing sheet 5 is made.
  • This welding can e.g. be a hot air welding. This welding creates a cohesive connection between the film part 4 and the sealing membrane 5 between the location of the circumference of the plate section 1 and the location of the circumference of the disk-shaped film part 4, which also creates an absolutely tight connection here.
  • the threaded rod 6 can now be screwed into the blind hole 3 of the pin section 2.
  • a reinforcement plate 15 can now be arranged, which is locked to the threaded rod 6 by the nuts 8 and 9 in the same way.
  • other connecting parts made of metal and / or plastic e.g. Spacers 22 may be arranged in a generally known manner.
  • the reinforcement is then attached, for example a reinforcement network 17 here.
  • the second layer 13 of concrete is arranged, for example shotcrete again, in order to complete the suspended ceiling.
  • a sealing, curable plastic can be applied in the flowable state instead of the sealing membrane 5.
  • the nut 19 shown in FIG. 1 with the washer 20 is not present.
  • the plate section 1 is connected to the sealing membrane 4 by means of a connecting material or is welded by a heat seal.
  • the sealing layer is not broken through at any point by a part of the fastening anchor and thus there is absolute tightness. Furthermore, the threaded rod 6 in the concrete 18 is completely protected against corrosion.
  • the sealing layer for example the continuous sealing sheet 5 is formed, continues through the integral welding in the disk-shaped film part 4. This film part 4 is in turn integrally welded to the plate section 1, so that a continuous horizontal sealing layer is present up to the pin section 2.
  • This sealing layer now continues in the form of the wall of the peg section 2 (the peg section 2 is formed in one piece with the plate section 1), that is to say rises vertically in FIG. 1 and bypasses the end of the threaded rod 3 at the uppermost end in order to be on the opposite end Page come down again and continue over the plate section 1, the disc-shaped film part 4 in the sealing film 5.
  • FIG. 3 shows an embodiment in which the lining in underground construction is shown with the aid of the fastening anchor described. The following description is based on that of FIG. 2, and accordingly only the differences from the embodiment according to FIG. 2 are dealt with.
  • the reference number 11 designates the rock, the rock which is pierced to build a tunnel, for example.
  • a first layer of concrete is applied to this rock 12, for example shotcrete in a known manner. Because of The rebars obviously present here are again not clearly drawn.
  • the holes 14 are formed through this first layer of concrete 12.
  • the respective bore 14 can now extend into the concrete layer or even completely through it up to the rock 11.
  • the sealing layer 5, e.g. flowable plastic or a sealing membrane made of e.g. Soft PVC is applied to the side of the first layer 12 of concrete facing the excavated space.
  • the insertion of the anchoring, the sealing connection between the plate section 1 and the exemplary sealing membrane 5 and finally the arrangement of the second layer 13 of concrete here takes place according to the embodiment according to FIG. 2.
