The framework structural part (13) has at least two longitudinal frame bars (19) of freely selectable dimensions and transversal support parts between them. To the frame bar end parts (29) are connected connecting components (23) which in turn can be connected to a further framework structural part. The frame bars along their lowest cross-section define two angle legs (vb1,vb2), each extending at right-angles from the frame bar center line (CL) towards the nearest frame bar end part, forming a point of intersection (p) between the angle legs and the frame bar outer side (35). |
