Lightweight construction

Abstract

A lightweight construction, especially a greenhouse structure, comprises a plurality of pillars ( 12 ) arranged at the periphery of an area of said lightweight construction, said pillars ( 12 ) extending obliquely and outwardly so that an upper end ( 22 ) of said pillars ( 12 ) lies substantially in a vertical plane passing through a respective area border. According to the invention at least one of said pillars ( 12 ) comprises a supporting element ( 14 ), said supporting element being mounted onto said pillar ( 12 ) so as to define a predetermined inclination angle of said pillar ( 12 ).

1 . Lightweight construction, especially a greenhouse structure, said lightweight construction comprising a plurality of pillars arranged at the periphery of an area of said lightweight construction, said pillars extending obliquely and outwardly so that an upper end of said pillars lies substantially in a vertical plane passing through a respective area border, characterised in that at least one of said pillars comprises a supporting element, said supporting element being mounted onto said pillar so as to define a predetermined inclination angle of said pillar.  
     
     
         2 . Lightweight construction according to  claim 1 , wherein said supporting element comprises a horizontal bar, said horizontal bar being mounted adjacent a lower end of said pillar in such a way that the angle between said pillar and said horizontal bar equals said inclination angle of said pillar.  
     
     
         3 . Lightweight construction according to  claim 1  or  2 , wherein said supporting element comprises a vertical bar, said vertical bar being mounted onto said pillar so that the angle between said pillar and said vertical bar equals an angle complementary to said inclination angle of said pillar.  
     
     
         4 . Lightweight construction according to  claim 3 , wherein said vertical bar comprises an anchoring pole, said anchoring pole having a length greater than the length of the vertical leg of a rectangular triangle defined by said pillar, said anchoring pole and an imaginary horizontal line connecting a lower end of said pillar to said vertical leg.  
     
     
         5 . Lightweight construction according to  claim 4 , wherein said anchoring pole comprises at least one mark at the intersection between said anchoring pole and said imaginary horizontal line, said mark indicating the digging depth of said anchoring pole.  
     
     
         6 . Lightweight construction according to  claim 1 , wherein said supporting element comprises two oblique bars mounted onto said pillar, one of said oblique bars being mounted on either side of a imaginary vertical plane containing said pillar, said oblique bars extending downwardly in such a way that the lower ends of said bars and the lower end of said pillar define the corners of an horizontal triangle.  
     
     
         7 . Lightweight construction according to  claim 1 , wherein said supporting element comprises a supporting base, said supporting base being mounted adjacent a lower end of said pillar in such a way that the angle between said pillar and said supporting base equals said inclination angle of said pillar.  
     
     
         8 . Lightweight construction according to  claim 7 , wherein said supporting base comprises several rods extending outwardly from said lower end of said pillar in such a way that the outer ends of said rods substantially lie in a plane which is cut by said pillar in an angle equal to said inclination angle.  
     
     
         9 . Lightweight construction according to any one of  claims 1  to  8 , wherein said pillar comprises receiving means for receiving a horizontal distance element.  
     
     
         10 . Lightweight construction according to  claim 9 , wherein said distance element is a horizontal distance bar for mounting between the upper ends of two adjacent pillars.  
     
     
         11 . Lightweight construction according to any one of  claims 1  to  10 , wherein said pillar comprises a pedestal mounted on a lower end of said pillar.
