Roof for buildings, designed to recover solar energy, includes concrete panels with sealing, insulation, framework, embedded pipes and photovoltaic cells

摘要

The roof framework supports concrete panels (14) resting together, with projections on their underside. These are supported on a resilient layer (16) on the roofing framework. An external layer seals the panels. Pipes are embedded in the panels, to be connected to the heat exchanger of a thermal solar energy plant. Additionally or alternatively, solar cells are arranged on the outside of the concrete panels. In an otherwise similar construction, Steel, wood, reinforced concrete or grid supports are let into the underside of the panels. They connect diagonally down from an upper bracing strip (20) in the panels, to a lower bracing strip (24). A further variant is described, based on the foregoing principles. A further layer may be hung below the roof construction. Thermal insulation is included between upper and low concrete panels. A further grid construction for the support frame is described; this too, includes a resilient support layer.
