Bridging stone cover for caravans

摘要

The bridging stone cover (16) for caravans comprises boarding elements, with the lower side of stone cover built on the outer side of the back (2,2') of the boarding element. A shank (3,3') and bridge (4,4') are bound in a mixed concrete layer (15). Reinforcements may be present in the mixed concrete layer. At least one knob (11,11') may be arranged on the edge region on the inner-side of the back, and on both sides of the bridge, whose upper surface may have an incline. This incline may have an inclination of a recess (7,7') in the shank directed against it.
