Definitions

  • the loadings borne by the cover support members and legs in supporting the cover and in withstanding loads applied to the cover can be significant, and the cover support members and legs are designed in such a manner that they are able to withstand these loads.
  • the cover support members are typically formed from relatively thick walled tubes.
  • relatively thick walled tubes is disadvantageous in that it results in the loads having to be borne by the legs being increased, and in that the cover support members are of relatively costly form.
  • a polytunnel structure 10 that comprises a plurality of rows 10 of upstanding legs 12, each leg 12 being screwed or otherwise secured to the ground in a location in which a polytunnel structure 10 is desired, the legs 12 each extending generally vertically.
  • Each leg 12 includes an upright 14 and a bifurcated support region 16 defining arms or projections 18 that are angled to the upright 14.
  • the projections 18 are of non-circular cross-sectional shape, in the arrangement shown being of a hollow tubular form. It will be appreciated, however, that the projections 18 could be of solid construction, if desired, and may be of other shapes than illustrated.
  • cover support members 20 and projections 18 are substantially non- rotatably fitted to one another, the relative rotation therebetween that often occurs with traditional polytunnel structures having cover support members of circular cross-sectional shape as a result of the tendency of the cover support members to rotate and sag under their own weight is resisted.
  • the polytunnel structure is thus of enhanced structural rigidity.
