摘要

The base (1) has wedge-shaped, lightweight constructional components (10) comprising a fastening unit for fastening on a flat roof and/or for adaptation with adjacent components. Each component is designed as a hollow body and has a vacuum stable body. The components are made of plastic, air permeable foam material, recycling material or compressed natural material. The components are adapted with each other to form a construction set. Each component has a vacuum valve (50) penetrating through a front wall (11), and a fastening edge (20) made of a material corresponding to the roof material.
