Definitions

  • Our invention refers to a thermally welded plastic sheet destined for covering cultivations of vegetable or animal productions. These constructions consist of the framework and covering material, which in this particular category are sheets of plastic. These plastic sheets are fixed on the framework by: a) special clips ( there are several inventions ) b) wires c) the weight of the ground after the edges of the sheets have been covered in ditches d) several systems that combine two or more of the above cases
  • the goal of our invention is to create a product with such a low investment cost that makes it worth covering products of very low value.
  • the above can be realized by the creation of cylindrical water storage tubes of the same plastic material that are thermally welded on the plastic sheets that cover the cultivations.
  • Our invention renders indispensable expensive greenhouse frameworks, metal water drains and all types of clips that hold the sheets on the roof. Its advantages are:
  • connection means (unnecessary use of clips)
  • the water works as a means of storing energy, by collecting the heat of the sun and maintaining the temperatures during the night.
  • Step 1 Fold the left and right sides of a plastic sheet (1) that has the appropriate dimensions.
  • Step 2 Thermally weld the water storage tubes (2) on the folded edges of the plastic sheet, leaving on both sides a portion of the plastic sheet in excess (3)(fig. 2)
  • Step 3 Cut into strips the portion of the plastic sheet that is left in excess (4) and form webbings (5) in order to avoid further tearing, (fig. 2 and 3)
  • Step 4 In the middle and underneath the main plastic sheet thermally weld an extra sheet (6) with the edges also formed by strips (7) and webbings (8). ( fig. 4)
  • Step 1 Fold the left and right side of the plastic sheet (1) with the appropriate dimensions leaving a larger part of the sheet in excess in comparison to the first way of production described above. Form the storage tubes (2) by thermally welding the excess sheets(9) ( fig. 5 )
  • Step 2 Cut into strips of 50 centimetres the portion of the plastic sheet that is left in excess after the tubes are formed (4) and make webbings at their ends (5) in order to avoid any further tearing, (fig. 5)
  • Step 3 Thermally weld in the middle of the main sheet an extra plastic sheet (6) that is also cut into strips (7) and has webbings (8) (fig. 6) Below find an application of our invention. Covering two successive cultivation areas:
  • Step 1 Fix three lines of stakes on the ground, (fig. 7)
  • Step 2 Form ridge by placing steel wires on the stakes, (fig. 8)
  • Step 3 Place the thermally welded plastic sheet on the steel wires in the middle of the sheet where the extra sheet has been additionally welded. Tie the strips of the extra plastic sheet to the ridge. ( fig. 9)
  • Step 4 Tie together the plastic strips on each side of the consecutive sheets, (fig. 9). The cavity that is made at each connection point is used as a water drain. (10) Step 5: Fill the tubes with water. With the above a roof of a green house construction is made.
  • the number of the water storage tubes depends on the width of the basic construction unit. The more water storage tubes the better the weight of the water can confront the sub-pressure that is created by the highest winds in the area of the installation.

Abstract

La présente invention concerne une feuille plastique soudée thermiquement, destinée à la couverture de constructions de serre, qui une fois repliée et soudée thermiquement, constitue des tubes de stockage d‘eau (2). Une fois que l’on a replié la feuille, on laisse une portion superflue de la feuille plastique pour former des bandes (4), qui se raccordent aux bandes correspondantes de la feuille plastique suivante. Au milieu de la feuille plastique et entre les tubes créés plus haut, une feuille plastique supplémentaire (6) est soudée thermiquement pour permettre avec les bandes (7) la fixation de la feuille plastique au sommet de la construction. De cette manière, la feuille plastique proprement dite satisfait les besoins de fixation sur le châssis de l’installation et le reste des feuilles tout en créant, au niveau des pièces de connexion, les drainages d’eau indispensables (10). Les tubes de stockage d‘eau subissent, sous l’effet de leur propre poids, la sous-pression des vents, de telle sorte que tout le système puisse être en mesure de garantir la résistance nécessaire à l’humidité.
