One unit consists of 24 modules Each unit consists of 5 x 12 modules in portrait orientation. The mounting structure is inclined by 25 in North-South direction. The total dimensions of the mounting structure are aprox. l/w = 12,2/2,75 m. The distance between top ground surface and lower edge of the module is approx. 0,80 m.The module bearing structure consists of 4 pairs of 2 columns each which are fixed to Sigma poles. The height of the Sigma poles above top ground surface is 20cm. The cross bracing is realized through diagonals which are mounted between the columns of one column-pair. The cross beam (vertical direction) is fixed onto the column-pair. The module bearing rail (horizontal direction) is fixed onto the cross beamsAll parts instead of screws, nuts etc. are made of extruded aluminum profiles. The Sigma poles are made of galvanized steel. 28 m/s0,49 kN/mSigma Blatec - Bulgaria DESCRIPTION0,75 kN/mDY = 3.100 DY = 3.100 DY = 3.100 DY = 10.800 4Seite : Sigma Blatec - Bulgaria DESCRIPTIONAngaben zum BaugrundFr den Standort liegen keine Angaben zu den Baugrundverhltnissen vor.
