Definitions

  • the invention relates to a greenhouse, consisting of a supporting framework structure and a flexible and transparent roofing.
  • Such greenhouses are known with a cover made of transparent PE film instead of glass.
  • Glass coverings or glazing made of glass have the disadvantage that they are not sufficiently resistant to weathering. This problem arises in particular with hail since glass sheets are relatively brittle and fragile.
  • the invention is therefore an object of the invention to improve a greenhouse of the type mentioned in terms of the disadvantages described above.
  • PVC polyvinyl chloride
  • the PVC skin of the greenhouse according to the invention is thus mechanically higher loadable, therefore easier to attach and resistant to hail and high wind load.
  • Another advantage of the greenhouse skin according to the invention is the fact that it is self-extinguishing in the presence of fire, whereas PE burns independently.
  • the PVC film is UV stabilized to prevent yellowing.
  • Its thickness may be about 0.3 to 2.0 mm, preferably 0.5 to 1.4 mm.
  • the UV stabilization of the covering is chosen so that light wavelengths below the photosynthetically active region are largely shaded. That is, the clear plasticized PVC film used is designed to be an optimal light transmission, ie on average over 90%, in the wavelength range between 380 and 700 nm. The shorter wavelength range outside this window is shaded by appropriate adjustment of the UV stabilization, ie there the film preferably has an average spectral transmission rate of less than 10%.
  • the radiation reduction is effected by absorption in the film.
  • the greenhouse shown in the drawing consists of a framework structure 1, in the form of a braced skeleton, for example of light metal rods, which is covered with a transparent PVC skin 2 as roofing.
  • the PVC skin 2 may be formed one or more parts depending on the size of the greenhouse. This can be fastened to the frame structure 1 with appropriate fastening means, for example tapes, cords, Velcro and push-button connections or by edge clamping, possibly with clamping rails.
