Definitions

  • the invention relates to a double-walled lining element consisting of two large-area lining panels which can be used as lost formwork, in particular for concrete structures, and a method for its production.
  • Linings are used for a variety of applications e.g. used for tanks, pipelines, channels, etc. made of concrete as chemically resistant, liquid and gas-tight protection.
  • lining elements consist of a lining plate made of thermoplastic material, which by means of a plurality of anchor nubs with e.g. the wall of concrete structures are connected.
  • a double-walled design of the lining is required. This means, for example, that the container walls are to be protected by two liquid and gas-tight lining layers.
  • liquid- and gas-tight containers made of thermoplastic materials are known, which e.g. be placed in a concrete container interconnected with the lining plates described above.
  • This measure has the disadvantage that e.g. the inner container holding the liquid has no non-positive connection with the concrete structure and / or the lining plate fastened directly on the concrete and therefore cannot absorb any rearward or lateral forces or is not protected against displacement.
  • the invention is based on the object of providing a large-area lining element which can be used as lost formwork and consists of two lining panels which are essentially parallel to one another with a continuous space between the two panels and a method for their production, the two panels being available are non-positively, liquid-tight and gas-tight.
  • a first lining plate produced according to conventional methods and provided with welded-on anchor knobs is connected to a further, second lining plate by means of several connecting knobs.
  • the connection knobs are attached to the second lining plate and are inserted into holes in the first lining plate and welded to it in a liquid-tight and gas-tight manner.
  • the free part of the connecting knobs between the two lining plates defines their distance.
  • the advantages of the invention consist in the fact that the two lining plates can be firmly connected to one another and secured against displacement and that any leakage fluid that occurs can be connected between the two lining plates.
  • lining systems for differently shaped constructions can be assembled inexpensively and simply by means of the lining element according to the invention, and there is a positive connection between the lining plates.
  • the various parts of the lining element such as the two lining plates, the anchor knobs and the connecting knobs, preferably consist of plastic, thermoplastic plastic being particularly preferred.
  • FIG. 1 shows a cross-sectional section of an embodiment according to the invention fastened to a concrete wall
  • ⁇ *. 2 shows a cross-sectional section of another variant 35 of the embodiment according to the invention according to FIG. 1, 3 shows a cross-sectional section of a lining system according to the invention in the area of a lateral connection of two lining elements, and
  • FIG. 4 shows a cross-section of a lining system according to the invention in the area of a corner connection of two lining elements.
  • the lining element according to the invention consists of a first and second lining plate 2 or 4, which are connected to one another by means of a plurality of connecting knobs 6 to form a continuous space 7.
  • the first or outer lining plate 2 has, on the side facing away from the second or inner lining plate 4, a plurality of anchor knobs 3, with which the lining element in e.g. the wall of a concrete structure (container, channel, pipeline, etc.) can be attached lying down.
  • the second or inner lining plate 4 stands with the content of the concrete structure e.g. in contact with a water-polluting liquid.
  • FIG. 1 shows an example of the connection of the second cladding panel 4 to the first cladding panel 2, which is fastened in the concrete 1 by means of the anchor knobs 3.
  • connection knobs 6 fastened to the lining plate 4 penetrate the bores 5 in the lining plate 2 and are welded to the rear of the lining plate 2.
  • the connecting knobs 6 in the outer part facing the second lining plate 4, adjacent to the first lining plate 2, have a larger cross section than the bores 5. In this way, they sit on the lining plate 2 and form a defined distance and thus an intermediate space 7 from the lining plate 4.
  • the connection of the connecting knobs 6 with the first lining plate 2 is liquid and gas tight, so that no liquid or gases can get behind the lining plate 2. Any leakage fluid, caused by leaks in the second lining plate 4, flows into the continuous space 7 and can be drained off.
  • the connecting knobs 6 ensure a non-positive connection between the first and the second lining plate 2 or 4, so that rear forces are absorbed and a displacement of the second lining plate 4 against the concrete structure is reliably prevented.
  • connection knobs 6 can already be welded to it in the plane of the first lining plate 2 and not on its rear side.
  • connection knobs 6 can be connected to the first lining plate 2 by fitting by means of hot pressing.
  • the lining element according to the invention preferably consists of a thermoplastic material.
  • Fig. 2 the connecting knobs 6 are riveted to the lining plate 2 on the rear side thereof.
  • the liquid and gas tight seal is achieved by means of acid and / or alkali-resistant O-rings 16 which are arranged on the shafts 17 of the connecting knobs, adjacent to the walls of the bores 5, and by the widening of the shafts 17 which occurs during riveting be clamped between the connecting knobs 6 and the walls of the holes 5.
  • the O-ring 16 can be held in place during the assembly of the lining element by a conical expansion of the shaft 17, by a groove or by means of a fitting clamp.
  • the embodiment according to the invention shown in FIG. 2 allows also the use of different thermoplastics in combination, such as polyethylene (PE) and polyvinylidene fluoride CPVDF).
  • FIGS. 3 and 4 several lining elements according to the invention can be connected to form a lining system.
  • Fig. 3 shows the connection of two lining elements on the side wall e.g. a concrete structure 1.
  • the first lining plates 2 are connected to one another on a strip 11 by the welding point 10 and are sealed off from the concrete wall.
  • the second lining plates 4 are welded to the welding points 9 with a sealing strip 8 and compared to e.g. sealed with a liquid.
  • FIG. 4 A corner connection according to the invention in a lining system according to the invention is shown in FIG. 4.
  • the first lining plates 2 are connected to one another by a corner connecting strip 13 (e.g. 90 °) welded at the welding points 14.
  • the second lining panels 4 are e.g. connected to one another by a quarter-circle connecting piece 12 which is welded to the inside of the welding points 15.
  • corner connecting strips 13 the angle of which is greater or less than 90 °
  • differently shaped connecting pieces 12 are also conceivable within the scope of the invention.
  • the lining elements according to the invention with the intermediate space 7 formed between them can furthermore form a leak detection system, as a result of which a significant increase in safety is ensured when transporting or storing dangerous liquids.

Abstract

Elément de revêtement à double paroi, comprenant deux plaques de revêtement de grande surface utilisables comme coffrage perdu, notamment pour des constructions en béton. Ces deux plaques sont assemblées par liaison de force, de façon étanche aux liquides et aux gaz, et forment entre elles un espace intermédiaire. L'invention empêche tout déplacement des deux couches de revêtement, tout en permettant l'écoulement d'un liquide de fuite pouvant éventuellement se présenter. Grâce à l'invention, il est possible d'assembler de façon simple et à moindre frais, des systèmes de revêtement pour des constructions de formes diverses.
