Abstract: A structural support for frame and grid constructions of vehicle cabs and transport elements includes at least two profile parts, e.g., an outer profile part and an inner profile part, the profile parts being connectable together such as with an adhesive. Preferably the outer profile part is made of a metal such as aluminum, and the inner profile part is made of a plastic and particularly a fiber-reinforced plastic.

Abstract: The clamping type compressive joint made between a continous section (10) and a component (14) is created by means of at least one clamping plate (16) that can be introduced from the front into an undercut groove (12) and rotated by a securing bolt (18). On tightening the securing bolt (18) the continuous section (16) is partly deformed by the clamping plate/plates (16). Each of the section flanges (22), which tend to taper in cross-section in the direction of the longitudinal opening (20) of groove (12), features at least one weakening notch (24) running in the longitudinal direction (c). Clamping cam tips (26) on flanges (22) lying beyond these weakening notches (24) are, after tightening the securing bolt (18), plastically deformed in the region of the clamping plate/plates (16) which is/are essentially in plan view in the form of a parallelpiped and is/are rotated 30.degree.-60.degree. in the groove (12).
