Definitions

  • the invention relates to a device for sealing floors according to the preamble of claim 1.
  • a double-walled collecting trough for environmentally hazardous chemicals or the like is known, which, depending on the size, can be divided into sub-sections to be tested separately by welding corresponding sections of the base plate and cover plate to one another.
  • a double-walled sealing of floors is also known from the special print "New standard - double sealing for water-polluting liquids and special waste" of the GFA - Deutschen fürface-Abdichtung mbH, Hamburg (special printing from “Umwelt +technik", issue 10 - 1990) , in which the surface to be sealed is divided into individual sectors or individual segments. According to the prior art, this subdivision is carried out by welding the two plastic plates.
  • the protective concrete which is generally used as the top cover, must be pried open and the corresponding segment of the double-walled seal must be separated and removed.
  • the invention has for its object to design the generic device so that an improved and secure sealing of the individual sealing segments is ensured with each other and that the replacement of individual sealing segments is facilitated in the event of damage.
  • the double-walled seal for forming the individual segments is divided by thresholds, which are formed by double-walled edging of the seal with a sealing cover.
  • the replacement can be carried out completely with the appropriate protective concrete layer.
  • the protective concrete layer and the upper wall of the double-walled seal are replaced in individual steps.
  • the distance of up to 5 cm between the individual segments which is poured with mortar, concrete or the like, improves the interchangeability of the individual segments and prevents the risk of damage to a neighboring segment during replacement. Furthermore, the stability of the folds is increased.
  • welding or soldering the double-walled seal at its open ends further improves the tightness of the seal and reduces the risk of substances penetrating into the cavity or test space located between the walls.
  • a device for sealing floors according to Figures 1 and 2 consists of a double-walled seal 2 and 3, which is divided into separate test cavities 4 forming individual segments 1.
  • the double-walled seal 2 and 3 is divided by thresholds 5.
  • the thresholds 5 are formed by double-walled raised edges of the seal 2 and 3 with an overlying cover 6.
  • the individual segments 1 of the device are filled with a protective concrete 10.
  • spacer warts 7 are attached to the upper wall 3 of the seal 2 and 3.
  • plastic anchors 14 can be attached to the lower wall 2 of the seal 2 and 3.
  • the two lower walls 2 of the seal 2 and 3 can be welded or soldered together.
  • the cover 6 can be welded or soldered to the upper wall 3 of the double-walled seal 2 and 3 (weld seam 9).
  • the cover 6 can be flush with the bottom surface 11.
  • the cover 6 can also be covered by the protective concrete layer 10.
  • the double-walled seal 2 and 3 can be welded or soldered at its open ends 16.
