Definitions

  • the invention relates to a roof element according to the preamble of claim 1 comprising a hollow plate-shaped roof body, which has a one-piece support trough and at least one web protruding therefrom or out of the trough from the tub material, and at least one collector device for solar energy.
  • the DE magazine “Solar Principal Ulm”, edition 1995, pp. 1 1 -16 shows a roof element with a flat solar collector, which is mounted on an existing inclined roof pitch with a roof covering.
  • a roof element is used as a single component up to one Size of maximum 12 m 2. Larger areas are realized by interconnecting several elements, but this creates a large edge area on the roof pitch. However, a large edge area on a solar surface leads to greater cooling.
  • the roof element with integrated collector device stands out from a conventional one Roof cover.
  • the DE prospectus "Solar Fox" from Johann Kalkgruber in A-4400 Steier describes a roof element with an integrated collector device for solar energy, is mounted on a conventional sloping roof with a roof covering and also rests on it.
  • the arrangement has a weatherproof and tempered cover element made of approx. 4 mm thick glass and differs significantly from a conventional roof covering.
  • DE-U-9208387 shows a roof element which rests on an under-roof construction, has a roof body with a support trough and cover elements which, arranged on webs, cover the entire arrangement.
  • the cover elements consist of a large number of customary roof tiles.
  • a solar cell device is provided with the overlap area between adjacent and / or stacked roof tiles, with which solar energy can be converted into electrical current.
  • DE-A-2807487 shows a roof element which consists only of roof tiles. This arrangement has joined roof tiles that rest on a roof support. Each roof tile has a cavity in its interior, in which a collector device for solar energy is arranged (roof tile collector). These hollow roof tiles are placed on the roof support. On the outside there is an adaptation to conventional roof areas. However, the roof element has several cover elements, which in turn have a large edge area, which lead to a large cooling and thus to a low thermal efficiency of the roof element.
  • DE-A-3000289 describes a roof element which consists of a cast material, in the interior of which a tube arrangement forming a collector device is cast.
  • the roof element is a compact body, whose outward-facing surface is colored and profiled to match conventional roof surfaces.
  • a roof body with a support trough and webs, on which a cover element is arranged, and cover elements which cover the roof element are not present. This arrangement also has a low thermal efficiency due to the compact dimensions of the roof element.
  • DE-U-29506798 shows a roof element with a roof body and a collector device for solar energy integrated therein.
  • the roof element is arranged between two rafters.
  • a glass plate is provided as the cover element, which is enclosed within the rafters and cannot be removed.
  • DE-A-3124992 shows a roof element with prefabricated roof bodies, to which a collector device for solar energy is assigned.
  • This device is characterized in that the roof body is designed as a self-supporting, ribbed concrete slabs, and come with their ribs to the outside.
  • the collector device is arranged in depressions between the ribs.
  • a sun-permeable covering device covers the recess. The side facing the sun is smooth and corresponds in its surface structure to a conventional glass cover.
  • the object of the invention is to provide a roof element as a solar roof according to the preamble of claim 1, which does not differ in appearance, weight and dimensions from conventional roof elements and can be assembled inexpensively.
  • this object is achieved by the characterizing features of claim 1 in that the cover element is colored and profiled, at least in adaptation to the conventional roof surface.
  • the cover element according to the invention visually resembles most regionally different roof structures, so that a roof consisting of the roof elements according to the invention resembles the usual roofs without impairing the aesthetics.
  • Visually striking structures are added to the surface of a cover element by appropriate, targeted admixtures of dyes or dyed fibers during manufacture. This takes place either in one layer with an attached structure or else in two layers by edging or deep-drawing the structure on an upper and / or lower layer of the cover element.
  • the structure can also be achieved by spot welding the layer to be structured to the element only at a few points and pressing the layer to be structured against a mold under pressure.
  • the support trough is closed by a single cover element.
  • This extends the roof element to size of a complete roof. There is no need for intermediate cooling between the individual elements. This reduces assembly costs and saves the cost of fasteners.
  • Such large-area roof elements with full roof function can also be manufactured industrially and make it possible to use large-area and powerful collectors and elements with significantly higher or differentiated performance, as with the usual collectors or elements, at reduced costs and thus lower the running energy costs of a house as well , such as in particular the initial equipment costs in relation to the comparable range of services. Possibly slightly higher transport costs of such large solar elements, which, however, can only be significant for long distances, are compensated for by the advantages provided by the higher energy exploitation.
  • Such a large-area element preferably has a surface with a dimension of at least 16 m 2 or an edge length of at least 4 m. so that overall a higher overall use is possible, as seen on the entire roof area.
  • the cover element consists of a weatherproof glass or of a translucent plastic or ceramic material. It is crucial that the material of the cover element meets the requirements of a conventional roof covering in terms of weather resistance, hardness, density or similar mechanical properties, but without reducing the light transmission or heat transmission. If they are made of glass, these cover elements must be heat-resistant and also meet a specific weather requirement or also be thermo-elastic. These mechanical or thermal properties essentially determine the selection of the material of the cover element.
  • the outside profiling of the cover elements is advantageously arranged in such a way that it has a roof-tile, slate-roof or shingle-roof-shaped structure.
  • Such roof arrangements are customary in many areas and conventional. It goes without saying that when structured differently Roofing in other countries or other areas other structures are possible.
  • photovoltaic elements for the direct conversion of solar energy into electrical current can advantageously be arranged on the outer surface of the cover element.
  • Such photovoltaic elements are flat, flat modules that are applied to the cover element, usually glued or cast. Several such modules are then connected in parallel and used as solar power. Due to the structure of the cover element according to the invention, the individual modules each have an area which corresponds to that of a “roof tile”.
  • a roof body in each case comprises a roof half of a roof, on the lower longitudinal side of which a gutter for rainwater or a collecting device for snow is arranged, the vertical sides of which form a roof ledge and the upper longitudinal side of which forms a roof ridge.
  • the roof element can be converted into a complete roof with roof structures such as a ridge dormer, windows, chimneys, roof balconies, roof terraces, roof riders and dormer windows.
  • Such an arrangement can then advantageously be removed as a whole from a support, is then transported and placed on a remote roof support.
  • Roof pads are, for example, the upper edges of the outer walls of a house, building or other structures that have a roof structure in the form of a flat, gable or other structures. Because the arrangement can be transported, the industrial production of a roof element described above is further improved with all the advantages that such a production method usually brings.
  • a single roof element is, for example, manufactured on a special device as a roof half and assembled to form a complete roof. The complete roof is then placed on a support using lifting equipment or other means of transport, for example on a prefabricated house that is also manufactured industrially. So that such a roof can also be used advantageously in relation to different requirements, it is advantageous if the roof has a value between 0 and 80 ° adjustable tilt angle.
  • the suspension or connection device necessary for transport or for the connection to a building or foundations can already be attached or cast into the roof structure during the manufacturing process.
  • the tub material advantageously consists of a mineral material, with lightweight concrete being preferred.
  • This material is light and at the same time allows the support trough to be appropriately stable.
  • a particularly advantageous embodiment of the support trough is, for example, a lightweight concrete honeycomb construction in which honeycombs in connection with a glass fiber or mineral fiber, carbon fiber or carbon or graphite fiber reinforced light concrete layer takes on the support function function.
  • the honeycomb material core which is made of polypropylene or another plastic, for example, the same admixture and filling of the plastic with wood flour or perlite and the like can take place, which also contributes to weight and cost reduction.
  • the support trough for the roof element is advantageously arranged in each case between two roof beams of a roof, which run perpendicular and / or parallel to the longitudinal sides of the roof elements and form the webs for the roof covering element.
  • the support trough of the roof element according to the invention can thus be integrated into a fixed frame and largely recessed into it, which is formed by the roof structures or by a similar lateral delimitation in the case of a single roof element. This means that the support trough is stored in a stable manner and is protected against external torsion.
  • the roof beam arrangement thus also forms the webs on which the cover element can be attached. This makes the roof element a complete part of a conventional roof construction.
  • the collector device for solar energy advantageously comprises a reflector, an absorber device, a fluid heated by solar energy and heat dissipation devices, the heat of the fluid being made usable via supply and discharge lines arranged on side edges of the roof element.
  • the fluid can advantageously be a liquid or air, which can in each case be supplied to the heat dissipation device via transmission media.
  • a transmission medium for example, a pipe can be used, which is installed with or without an absorber in a serpentine, segment-wise or grid-like manner as a register as a whole over a whole roof element with a lower and upper supply and a lower and upper discharge for the heat-carrying fluid.
  • the collector device for solar energy is advantageously arranged in a cavity delimited by an inside of the support trough, an underside of the cover element and by the lateral webs.
  • the collector device is thus integrated in a chamber arrangement which is covered by the removable and removable cover plate.
  • a chamber is advantageously first manufactured without a cover element and installed in an existing roof structure. After installation, the chamber is covered like a plate by the cover element structured on the outside. During subsequent maintenance or removal of parts of the roof element, the cover plate is simply removed so that the individual parts are easily accessible and can be easily replaced if necessary.
  • the elevation of the surface to a wave crest then advantageously forms the web projecting from the when and thus a support for the cover element.
  • a wave trough formed in this way is advantageously coated with a reflective material and serves to hold the complete collector device. It is further advantageous if the wave trough has the curvature of a concave mirror whose focal point, extended along the surface in the form of a surface, has the absorber devices with the heat dissipation device.
