A shed roof of conventional design is heavy and complex and meager in terms of thermal insulation and room acoustics; Cracks often occur on concrete parts of the roof due to different temperature expansion and floor displacement.

It is an object of the invention to remedy these shortcomings, that is, to propose a shed light roof which is inexpensive and reliable and meets all of today's requirements for sound and heat insulation.

This object is achieved with the characterizing features of claim 1. Because the Shedlicht roof according to the invention can advantageously over a rectangular section of a reinforced concrete, z. B. from TT panels (panels with double T-webs), or HP shells (hyperbolo-id-shaped shells) existing flat roof can be attached in that on the circumference of the cutout mainly made of wood e.g. Layered squared timber frames are placed on edge; the frames on one long side carry a profiled sheet metal strip made of galvanized steel, which has a support surface that is inclined at 60 ° to the horizontal and an adjoining support surface that is inclined at an opposite angle of 30 ° for rungs made of square tubing arranged at a distance from one another. Glass panes, namely in the form of single glazing or insulating glazing, rest on these with a known interposition of strips of flexible material; these sit with a part projecting downwards over the rungs on another holding surface of the profiled sheet which is again inclined at 30 °. The frames on the other long side of the cut-outs carry a profiled sheet metal strip made of galvanized steel, which has a support surface for the roof covering that is inclined at 30 ° to the horizontal.

The two support points on the frames and the connection point on the roof ridge are so flexible, despite being screwed together, that different temperature expansions and floor displacements cannot cause cracks in the concrete roof.

This joint property is not hindered by the roof covering; it can be a trapezoidal corrugated sheet, in particular made of light metal, which is covered by a sheet of thermal insulation material, in particular mineral wool, with another sheet protruding downwards beyond a trapezoidal corrugated sheet. This roof covering does not require any rungs.

For roofing, however, rungs made of square tube can also be provided, which are aligned with the first-mentioned rungs of the glass panes and are connected by screws across the ridge; these rungs are supported on the abovementioned bearing surface and on a subsequent holding surface of the profiled sheet metal strip which is inclined at an angle of 60 °.

On these rungs are either transparent double-wall sheets, z. B. from acrylic glass or an opaque roof. This can be made of a smooth or perforated steel sheet. or a layer of chipboard with plates of thermal insulation material, in particular mineral wool, and a sheet of trapezoidal corrugated sheet, in particular made of light metal, covering the outside. The latter then lies on a further contact surface of the profiled sheet metal strip which is again inclined at an angle of less than 30 °.

The roof coverings discussed are much lighter than the known roofs; they result in significantly better thermal insulation and room acoustics. These favorable properties also apply with regard to the further features which are stated in the subclaims; they relate to the special design of the gable walls, the covering on the roof edges and the ridge as well as other details of the shed light roof.
