The supporting framework comprises two-part binders having respective separate profiles (1a, 1b) which have respective upper flanges (3a, 3b) and webs (4a, 4b) and which extend along each other from web (4a) to web (4b) in a mirror-inverted manner. The binders are interspaced and supported on struts (9), the upper ends of the struts (9) being braced between the webs (4a, 4b) of the profiles (1a, 1b) and a layer of purlins (5) being arranged on the binders at a right angle. Each purlin (5) is clamped onto both upper flanges (3a, 3b) by means of clamping elements (16a, 16b), an undercut threaded channel (15a, 15b) being integrated into every upper flange (3a, 3b) for screw connections (17a, 17b) with which the clamping elements (16a, 16b) are braced to engage with. |
