It is now known to use additional elements in such roof structures to use the air conditioning of the building or the heat recovery from the incident solar radiation or that supplied by the wind Serve circulating air temperature. These additional elements are generally a burden the roof structure, d. H. the roof becomes heavier and more complex with otherwise constant requirements.

According to the present invention, novel components are now to be proposed which replace the previously common elements, such as roof tiles, roofing felt, sheet metal or the like. And which are used to build climate roofs suitable.

The characteristics of the new type of component result from the identification of claim 1.

The invention is based on the basic idea that to build Plate-shaped or strip-shaped extruded parts made of metal or plastic are suitable for climatic roofs. To the knowledge of the applicant, such Extrusions have not yet been used in the relevant technology. The closest thing to the subject of the invention are sheet metal roofs, which are assembled from longer sheet metal strips. The edges of the metal strips are generally bent upwards at right angles. One Edge also has an envelope. The envelope is pushed onto the edge of the adjacent sheet metal strip. Then will the connection is flanged one or more times using a continuous tool. In this way, a closed outer skin is created of the roof, which, however, is not suitable for accommodating supporting elements or for drilling that carry a heat exchange medium.

The extruded parts proposed according to the invention can be priced produce in the order of magnitude of the metal strips previously used.

Flg. 13 cross sections of elements in combination with each other

to build a roof use and

15 shows a cross section with a tubular flow channel.

All of the elements shown in the figures can be up to 30 m Own length. However, they are relatively narrow, for example 30dm or 60 cm board, the cross-sections are extruded in continuous lengths achieved. The intended semicircular or hook-shaped bulges now fulfill a number of important functions, namely:

1. As long as the strip emerging from the extruder does not penetrate When cooling has solidified, they stabilize the strip. they allow

| i.e. the production of an extruded part with a relatively small wall thickness,

e.g. under 2mm.

| 2. They also enable relatively long elements and to be transported

craning them up onto the roof structure, i.e. bending or

s Kinking in the direction of the surface normal is prevented.

3. They enable the components to be connected to one another, with support

. share and with hollow parts, which carry a heat exchange medium.

In the cross section shown in Fig. 1, the extruded part consists of an essentially flat central section 1, on which there is an approximately semicircular bulge 2 on the left in the sense of the illustration, which protrudes downwards is directed, and on the right an approximately three-quarter circular bulge 3, which is directed upwards, connect. In the bulge 3 is a Broken pipe 4 indicated by dashed lines, whereby the inherent elasticity of the extruded part results in a full and highly thermally conductive system of the bulge 3 on the tube 4. Now is the next item hung with the bulge 2 in the tube 4, this partially resting on the tube 4 and partially on the outer surface of the bulging 3. Repetition creates a chain which can be braced transversely to the axis of the tubes 4 and which provides a rainproof seal. the

Pipes 4 can, for example, over the air duct or the track of a Roof to be arranged running horizontally. Between the outside of the? Hochwölbuing 3 and the inside of the downward bulge 2 are Hook-shaped tensioning elements are inserted in regular sections that are attached to the battens or rafters.

The tubes 4 therefore serve, on the one hand, for bracing and bracing the extruded prilt elements. On the other hand, however, they form a relatively dense network on the Daoh, which in series or parallel connection or a combination of both allows the flow of a heat exchange medium, ζ. Β. Air, water or a brine is used. The heat exchange medium can now z. B. serve to heat a visual swimming pool. Since the 'heat absorption of the surface of the Strangpreßelemente let greater than, for example, the heat absorption of a swimming pool surface, and since in a conventional Bungalowbau already the roof surface is generally about ten times larger than the area of an associated swimming pool, there is the result that the heating time of the swimming pool against normal solar radiation is reduced by at least a factor of 10. By switching on a heat pump, considerable amounts of heat can be withdrawn from the roof, which are then fed into the area by solar radiation or the air currents sweeping across the roof.

The embodiment shown in Fig. 2 differs from the embodiment according to FIG. 1 in that a downward bulging 5 and an upwardly directed bulge 6 are provided, which are U-shaped in cross section. Furthermore, they are hook-shaped Approaches 7 and 8 provided on the underside of the flat central part 1, which can fulfill various functions. On the one hand there is the level Central part 1 stabilized during manufacture, on the other hand, the hook-shaped lugs 7 and 8 allow bracing and fastening of the Extruded part on battens or rafters. So you can

Kotto described above, for example, by means of a cable winch under tension place, where mnn the wall hook, for example, in the hook-shaped Element 8 can intervene. By inserting sheet metal strips, the one Have envelope, in the hook-shaped approach 8 and nailing the sheet metal strip for example on the battens, the chain thus formed is then fixed under pretension to the roof structure, so that the winch tension can be released.

However, the hook-shaped lugs 7 and 8 can also be used to accommodate Thermal insulation panels are used that are spread apart.

Fig. 3 now shows the connection in Flg. 2 shown extruded parts with each other and with a drill 9 with a square cross-section, the tube 9 in turn acting both as a support element and as an air-conditioning component. "Air conditioning" should not only include the above-mentioned Heat recovery from the roof, but also any type of heat exchange with the roof can be understood. In tropical zones, for example the drill 9 can be used to cool the roof without the extracted heat is used. The drill 9 can also, for example, be used for automatic snow defrosting, e.g. B. by using hot air be applied.

The roof structures made with the extrusions according to the invention have the advantage that they are suitable for a wide variety of air conditioning tasks. Since the roof structure is not More expensive than a standard sheet metal roof covering, it's beneficial, too if air conditioning was not yet considered when the building was erected. However, you can also do it afterwards without any structural changes use some or all of the tubes 4 and 9 accordingly.

may have the same length as the associated extrusions. It however, shorter elements can also be used for reasons of economy which are "narrated at a distance from one another.

The hook-shaped connecting element 24 has a bearing surface 25 with which it is nailed or screwed to a rafter 26, a web 26 directed vertically upwards, on which a horizontal up- ' location surface 27 for one of the extruded parts described connects as well

a convexly curved receiving part 28. An extruded element 29, whose Side edge has an approximately quarter-circular bulge 31 towards the top in cross section, is hung behind the receptacle 28. A previous one Element 29 is hung with the downwardly curved side edge 33. A connecting and tensioning element is generally used tube not shown. In the embodiment shown, this can also be inserted subsequently.

In the embodiment shown in FIG. 10, there is a connecting element 33, which in turn has a flat support surface 34 resting on a rafter 26, which is turned over at 35 and at 36 is bent upwards in the form of a concave hook. The associated

Extruded parts 37 have right edges in the sense of the illustration an angled flat surface 38 which is pushed into the envelope of the connecting element 33. This surface is together with the connecting element as indicated at 39, nailed to the rafters 26. The left edge of the extruded part 37 in the sense of the illustration is approximately Bent into a five-eighth circle, as shown at 41. This edge embraces a tube, not shown, which finds a corresponding abutment on concave hooks 36 of connecting element 33 when braced.

The extrusions shown in Figs. 11 and 12 have on their in the sense of the illustration, the left edge has a web 42 protruding vertically upwards. The right edge is, as shown at 43, in cross section designed hook-shaped. The connection of the elements to one another takes place in that the hook-shaped edge 43 over the web-shaped Edge 42 of the next element is pushed.

In the embodiment of an extruded part shown in FIG five omega-shaped bulges 44 are provided, which are arranged at a distance from one another and run parallel to one another. These high arches 44 can now serve to anchor a plastic plate 45, indicated by dashed lines, which serves as a thermal insulation layer. Result here two alternatives. The plastic plate 45, which is generally produced as a foam body, can have webs that fit into the omega-shaped High bulges 44 are pressed. The plastic plate 45 can several of the extruded parts overlap, so that they are also in their Be fixed in position. Another alternative is to calibrate the Plastic layer 45 also from the manufacturer on the underside of the Can foam extruded parts.

You can now in one or more of the omega-shaped grooves 44 one Element or only certain elements spread hoses or bores,

which lead a heat exchange medium. However, corresponding hose sections can also be arranged in the webs 45 of the plastic plate 45 which then offer the advantage that they ensure better anchoring in the omega-shaped grooves 44 due to their inherent elasticity. In addition, the omega-shaped bulges 44 serve to stiffen the extruded part during manufacture and during of transport. They also muffle the crackling noise of the rain, especially in connection with a plastic plate 45.

The extrusion shown in Fig. 12 differs from that in 11 in that omega-shaped bulges 46 are provided, which are directed downwards. One made from such extruded parts produced roof structure can be air-conditioned at any time afterwards, for example, that in the omega-shaped Grooves 46, a black plastic tube is inserted through which, for example, water can flow.

13 and 14 show an example of a combined roof covering, d. H. it is not the same extruded parts, but two different series of extruded parts are used. It is understandable, that the chains formed can also contain more than two different extruded parts.

The extrusion shown in Fig. 13 has on its in the sense of Representation of the left edge of an envelope 47, which is adjoined by a flat side surface 48, which is divided into a semicircular and hook-shaped High arch 49 passes over. A flat central part 51 connects to the bulge 49, which in turn turns into a hook-shaped, curved in opposite directions High bulge 52 passes. The latter is followed by a flat side area ending in an envelope 54.

The element shown in Fig. 14 has a substantially planar one Middle part 55. The side edges at 56 and 57 are each approximately semicircular curved downwards.

The extrusion shown in Fig. 13 is 47 with its folds and / or 54 attached to battens or rafters, specifically by means of connecting elements, not shown, which also have an envelope own, which engages in the envelopes 47 and 54, respectively. Subsequently, tubes are spread into the hook-shaped high arches 49 and 52. Now, a compression molding as shown in Fig. 14, with his curved edge 56 applied to the drill, wherein it overlaps the hook-shaped bulge 52 and with its middle part 55 the flat side 53 and the connection point 54 and the gap to the following extruded part according to FIG. 13 are bridged. Another element according to 14 is placed with its curved edge 57 on the tube inserted into the hook-shaped high arch 49, with its central part the flat side surface 48 and the envelope 47 as well as the gap to the spaced-apart next element according to FIG. 13 bridged. Although not shown, it is understood that the elements according to FIG. 14 with their free edges 56 and 57 in the hook-shaped High arches 49 and 52 and engage in the inserted tubes of the adjacent extruded parts according to FIG.

In principle, it is also possible to use the extruded parts shown from sheet metal to manufacture, which is bent into the appropriate shapes. It turned out, however, that apart from the high amount of work involved, hardening of the material occur, which have an unfavorable effect in various respects. In particular, a full, elastic contact with the tubes can be impaired, as a result of which the heat transfer to the tubes is worsened. However, with combined roofing, it is sometimes advantageous to have one of the parts as an extrusion and another to be designed as a preform tes sheet metal part. For example, with the in

Likewise, the tension of the chain and the connection of the same with the rafters serving elements extruded parts or sheet parts being.

Furthermore, all parts or a part of the parts can be made of plastic be made. Here, taste aspects can also be a Role-play. For example, wood clapboard covers can be imitated; will. If the aim is to extract heat from the roof, then the plastic should have good thermal conductivity. This can be achieved through appropriate admixtures, e.g. of metal powder, and through appropriate inserts, e.g. of metal foils. When the Strarigpreßteüe If they are made of metal, they can also be enamelled, which is more complex, but increases durability and is particularly attractive Roof covers made possible.
