Abstract
The invention relates to a support structure of a cover of a structure capable of being inserted into the ground, for example of a shaft or a channel, wherein the cover () comprises a traversable surface () and the support structure () extends downwards under said cover into the structure and comprises beam-shaped supports (-) such that their under support side () facing away from the surface () experiences a tensile stress when the surface () is loaded. The invention is further characterized in that between two areas (A, A') a thickness (D) of the carriers with minimum tensile stress is configured substantially symmetrically in an increasing manner up to a maximum value and then, in turn, in a decreasing manner to form a ball shape when viewing the cover from below.
