The lower structure is composed of longitudinal and transverse supports which are made of an extruded aluminum alloy and are detachably connected to one another and to the upper structure by corner connectors. In interaction with the upper structure, it is of inherently sturdy construction. The corner connectors are, in particular, screw-on corner connectors.
