Definitions

  • the present invention relates to three-dimensional constructions which comprise at least one rigid plate, according to the preamble of Claim 1.
  • the present invention also relates to a method of producing three-dimensional
  • basins and containers are made of metal or concrete which, in these purposes of use, have totally replaced wood-based materials. Concrete basins are often cast in situ because of their considerable weight. Concrete is cheaper than metal but it presents major difficulties when it comes to recycling the material after the containers are taken out of service. Whereas metal is susceptible to corrosion and must be coated, during a separate production stage, with polymeric materials, for instance for corrosion resistant
  • thermoplastic materials have several advantages over wood and metal, particularly regarding, among other things, recycling and resistance to corrosion and decay caused by micro-organisms.
  • larger structures which are entirely or mainly comprised of thermoplastic material have not been available for construction purposes.
  • the containers produced have had a maximum diameter of approximately 3-4 m and only cylindrical structures have been possible.
  • rigid plates it is very possible to construct open basins and other non-pressurised applications of rigid plates, if these plates can be joined together reliably in order to generate compact structures.
  • Rigid plates for different structural purposes usually consist of thin solid plates which are stiffened by beams, such as beams having an L-or I-shaped cross-section or similar form.
  • the plate constructions are made by cutting out large plates and then modifying them by means of flexurally rigid beams of the abovementioned type.
  • a typical double wall construction therefore comprises two rigid plates arranged at a distance from each other and which form the surfaces of the construction and which are joined by intermediate, longitudinally or transversely running beams.
  • stiffening layers of beehive structure are also used. If, in practice, you want to produce polymeric double-wall plates of substantial dimensions out of thermoplastic material by means of extrusion, it is not possible to make such double-wall constructions thick enough because only a limited amount of heat can be removed from the beams binding together the surface layers in these double-wall constructions.
  • the purpose of the present invention is to eliminate at least some of the disadvantages associated with the prior art and to generate new solutions for basins, tanks and similar constructions.
  • the present invention is based on the idea that a three-dimensional construction is built by using a plate material which possesses a double-wall structure and which is comprised of elongated hollow profiles, which have essentially straight and parallel central axes and which abut each other and are joined together to form the abovementioned double-wall structure.
  • a plate material which possesses a double-wall structure and which is comprised of elongated hollow profiles, which have essentially straight and parallel central axes and which abut each other and are joined together to form the abovementioned double-wall structure.
  • Rigid plates made of thermoplastics offer the possibility of joining by welding, and the present invention therefore relates to a new process for the production of three- dimensional structures by joining at least two rigid plates, which are comprised of a plate- shaped thermoplastic material, formed of elongated tube profiles, each of which has an essentially straight central axis and which tube profiles abut each other and are welded together to form a double-wall structure, in which case the plates, when welded together, form a three-dimensional construction.
  • the plates are formed of hollow profiles, it is possible, if desired, to reinforce and anchor the construction by filling the cavities with, for instance, reinforcing bars or concrete mass.
  • the cavities can also be utilised for electrical wiring and even as pipelines for liquid media.
  • striped structures can be designed.
  • thermoplastic or metal plates of the present type welded together to form three-dimensional constructions, such as basins and tanks.
  • the present thermoplastic plates - and thus also the three-dimensional constructions made from these - exhibit good resistance to corrosion, decay and also mould.
  • the structures are composed of tube profiles, they are durably coloured and protected against UV.
  • the structures are easy to repair or modify. In relation to their mechanical properties, their weight is low, especially when comparing these structures with equivalent structures made of reinforced concrete.

  • the seam surface is separately prepared before the welding to ensure a good welding quality This can be done for example by mechanically working the seam in an initial sweep along the stack, for instance by using (chip)cutting machining and then by adding the molten plastic mass in a second sweep.
  • the preparation removes any dirt or oxidised surface layer from the welding surfaces. It is also possible to supply radiant heat or convection heat (e.g. by way of hot air) to the seam from a separate nozzle simultaneously with the welding of the previous seam.

  • the welding excrescence is shaped to the adjacent surface so as to produce a welded seam which, together with the side of the tube profile, forms an essentially flat and smooth surface of the plate.

  • Three of the hollow profiles 25 to 27 are identical, whereas one is wider 28.
  • the wider profile gives a greater flexural rigidity in the longitudinal direction of the profiles and in the direction of the structure, and thus forms a kind of reinforcing element for the entire construction.
  • the present double-wall structures are produced by using hollow profiles which comprise tube profiles, preferably hollow profiles of a thermoplastic material, which comprises one or more layers.
  • thermoplastic tube profiles are welded by using a thermoplastic material, suitably the same thermoplastic material which the tube profiles are composed of.
  • profile is used interchangeably with “tube” (i.e. an elongated object that has an open cross-section).
  • the thermoplastic profile is composed of 1 to 5 layers. According to one embodiment it contains several layers, in which case one of these forms the inner layer of the profile, and one the outer layer of the profile. Mainly in cases where a multi-layer wall comprises functional layers, it is preferable to arrange the functional layer separately in the outer wall (e.g. a conductive layer) or in the inner wall (e.g. a layer with good wear resistance).
  • the hollow profile comprises mainly or entirely conventional thermoplastic, such as a polyolefin, such as polyethylene, especially HD-PE, or polypropylene, polyacrylonitrile-butadiene-styrene (ABS), polyamide (PA) or another thermoplastic material.

  • a material of the latter type can be comprised of a thermoplastic material which has been made permanently conductive.
  • the thermoplastic material can be the same as that which is used in the core layer of the tube profile. Having this arrangement achieves good compatibility between the layers.
  • the cross-section of the tube profiles is typically rectangular, in which case the abutting sides of the tube profiles constitute at least 1/10 of the jacket surface of the tube profiles.
  • the term "rectangular" also includes such cases where the cross-sections of the tube profiles are quadratic or essentially quadratic.
  • the ratio of the width to the height of the tube profiles is preferably 1 : 1-1 : 10, in which case the ratio between the minimum thickness of the tube wall and the height of the cross- section of the tube profile is in particular approximately 1 : 100-1 :4, especially

In the figures, the profiles are joined together along the narrower side walls.

  • the type of plate shown in Figures 4a and 4b is straight and rigid. However, it can be shaped to exhibit a curved shape, such as an arch structure, and this curved shape can be rendered permanent.

  • elements which are essentially two- dimensional can also be produced for these three-dimensional constructions, i.e. the plates can form merely part of the construction, even though such a construction is three- dimensional, and the other sides are then comprised of conventional sides and materials.
