Definitions

  • the invention relates to a large-area double plate, in particular made of thermoplastic material. Thanks to the anchor knobs on the back, this double plate is particularly suitable for pouring into concrete or mortar and thus for corrosion protection of concrete structures. Between the plates there is a coherent leak gap, defined in its width, sealed on both sides, as defined in claims 1 and 2.
  • linings are increasingly being prescribed by the authorities, which are to be provided as a tight and durable double-jacket version with an intervening leakage gap as a monitoring space.
  • the linings have to consist of two permanent sealing layers, which are separated by a monitoring space, the leakage gap.
  • DE-A-3 830 439 discloses double plates of the type mentioned.
  • a method for producing a leak gap between two mutually independent plates is described.
  • the leakage gap is formed between a tight plate facing the stress side and a perforated plate lying behind it at a leakage gap distance, the holes of which, however, are not tight.
  • the leakage gap is therefore not enclosed by two tight thermoplastic sheets, so that liquid penetrating into the leakage gap can reach the concrete. As a result of these leaks, one cannot speak of two sealing layers.
  • the invention has for its object to provide a double plate, in particular made of thermoplastic material, which has a tight leakage gap, against external forces even with little use of material is stable and is simple and inexpensive to manufacture.
  • the invention is based on the following basic ideas.
  • a non-perforated front thermoplastic plate facing the load side is tightly and non-positively connected to a perforated rear thermoplastic plate via a multiplicity of thermoplastic anchor knobs protruding through the perforated plate while maintaining an intervening gap.
  • the part of the anchor studs protruding over the double plate is poured into concrete or mortar when the double plate is installed.
  • the connection of the two thermoplastic sheets to a double sheet is carried out so that both parts of the connected thermoplastic sheets represent their own sealing layer.
  • a major advantage of the invention is that the anchor knobs cast into the concrete for mechanically anchoring the double plate in a straight line and thus statically favorable passage derive the forces acting on the double plate into the ground.
  • the rear plate therefore has no forces to transmit or redirect and can be kept thin for the intended use.
  • Another advantage of the invention lies in the economical manufacturing possibility, which allows the double plate to be produced in one operation.
  • a front plate 1 facing the stress side is welded to another rear plate 3 facing a concrete side with the aid of anchor knobs 5.
  • the rear plate 3 has depressions 4 at the connection points to the anchor knobs, through whose openings 7 the cylindrical ends 5b of the anchor knobs 5 pass.
  • the anchor knobs 5 were welded on, their part 5b was connected to the plate 1 and at the same time a plate or a plate-like or flange-shaped widening 5a of the anchor knobs 5 to the recessed part 4 of the plate 3 by friction welding tightly and non-positively at joints 6b and 6a.
  • anchor knobs 5 serves to anchor the "double plate by pouring the anchor knobs into fresh concrete or mortar.
  • the size and shape, as well as the number of anchor knobs per m 2, depend on the requirements for uniform anchoring of those produced from the double plates Leak protection lining under assembly and operating conditions
  • the weld connection is preferably made by friction welding, eg vibration or rotation welding.
  • the plate 1 is connected to the plate 3 by means of rotational welding of the anchor knobs 5 extending through the opening 7.
  • a depression 10 located in the plate 3 when the anchor knobs 5 rotate, a simultaneous welding in the joints 6a and 6b is achieved.
  • the width of the leak gap 2 is determined by the depth of the depression 10. Due to a circumferential joint 9 in the plane of the plate 3 following the anchor knob 5, the plate 3 can expand somewhat in relation to the position of the anchor knob 5 and thus reduce the rigidity of the double plate during its assembly.
  • the double plate is produced by friction welding.
  • welding processes e.g. possible with heating element or ultrasound.
  • the plates 1 and 3 can also be connected to the anchor knobs 5 by adhesive technology.
  • the leak gap 2 of the double plate can also be divided by sealing strips 12 into a plurality of sections which are liquid-tight to one another.
  • the sealing strips 12 can be welded between the plates 1 and 3.
