Definitions

  • the invention relates to a plastic panel, in particular an extruded cellular thermoplastic panel.
  • French patent No. 1,256,507 already discloses a double-walled sheet of thermoplastic material which can be used particularly as a cover for greenhouses, rural buildings and the like, characterized in that its structure comprises two superimposed elementary sheets and a series of continuous intermediate diaphragms which are parallel to each other and joined to the two elementary sheets so that, when the elementary sheets are separated, a series of juxtaposed but not intercommunicating chambers is formed.
  • French Patent No. 2,073,791 a plastic panel characterized by the fact that it comprises two walls spaced from one another, which are connected together by a plurality of parallel ribs , spaced from each other, equidistant and perpendicular to the walls.
  • thermoplastics are beginning to find wide use in the field of construction.
  • all thermoplastics have the disadvantage of too much flexibility due to the open structure of the molecular chains, a disadvantage which is particularly noticeable if it is desired to use them with a large width between supports and with a small thickness.
  • a snow load of seventy five to one hundred kilos per square meter should be considered. Under this load, a bending of several centimeters is observed when using plastics such as polycarbonate, yet particularly rigid in its cellular structure.
  • plastics such as polycarbonate, yet particularly rigid in its cellular structure.
  • the edges of these panels rest on profiles and the panels under load tend, due to the bending due to the load, to escape from the profiles which support them.
  • French patent No. 1,347,592 already discloses a roofing element serving as an upper lighting panel consisting mainly or totally of a transparent synthetic material, which has on its opposite edges flanges making an angle with the adjacent main part. and allowing it to be placed on a roof opening in the manner of a hood, the main part being reinforced not only by the edges which have the shape of flat strips but also by the shape of its profile.
  • the element consists of two or more plastic plates which are spaced apart from each other at least over most of their surface and which are connected together at least on two opposite edges.
  • the aim of the present invention is to provide an element which is not subjected to bending work but to working in traction.
  • the opposite edges tend to approach, which increases the seal between the element in question and the metal structure.
  • the object of the present invention is to provide a remedy to the various difficulties mentioned above.
  • the invention as characterized in the claim solves the problem of creating a plastic panel, in particular a thermoplastic foamed extrudate panel primarily used in the greenhouses 1 which tensile strength is relatively high and of the order of four hundred to five hundred kilos per square meter and whose formation of fogging can cause the formation of algae inside the alveoli.
  • the panel designed according to the invention has a total seal produced on the lateral edges to prevent any penetration of foreign bodies and / or fluid into the cells due to a suction effect of these cells due to the pressure or the depression to which the panel is subjected.
  • the plastic panel 1 consists of two sheets 2 and 3 separated by parallel spacers 4, 5. This panel is an extruded cellular thermoplastic panel.
  • the transverse edges 6, 7, arranged perpendicular to the parallel spacers 4, 5, comprise a stop 8, 9 perpendicular to the plane of the panel 1. These stops 8, 9 are obtained during the forming of the panel 1.
  • each cell 10, 11 formed by the sheets 2, 3, the parallel spacers 4, 5 and the stops 8, 9, comprise an air or gas pocket subjected before drying.
  • the stop 8, 9 allowing the panel to work in tension and to make the best use of the performance of thermoplastics, also serves to make a connection between two panels 1 1 , 1 2 . It suffices that for the first panel II the stop 8 1 is directed upwards and that the stopper 8 2 of the second panel 1 2 is directed downwards.
  • This attachment principle is also used for the connection between the panels 1 1 , 12 and a profile 12.
  • the latter has on its sides a curved edge 13, 14 in which the stop 8 1 , 8 2 is hooked (see figure 3).
