Definitions

  • the invention relates to a roof structure with inclined first profile rails and transparent plates inserted between these profile rails, which have a slope and are inserted at their horizontally running lower edges in a second profile rail, which are connected at both ends to two of the inclined first profile rails and have a drainage channel for the discharge of water, which penetrates from the top of the plate located above the profile rail, the drainage channel opening into at least one outlet opening in at least one of the inclined profile rails.
  • the profile rails of such a roof construction form a frame structure subdivided into grid dimensions, in which the horizontal profile rails must also absorb the shear forces of the transparent plates in the direction of the slope.
  • the inclined first profile rails can also be referred to as "rafters and the horizontally running second profile rails also as” rungs.
  • plastic glass acrylic glass
  • rafters first profile rails
  • the high-strength plastic web glass panels were light in weight, which posed no particular problems even if the roof dimensions in the downward direction, i.e. the length of the «rafters», were several meters, for example more than 3 m.
  • the subject of the invention is intended for the subsequent glazing of balconies and verandas (old building modernization) as well as for new buildings for the upper end of bay windows, glass verandas, balconies and pavilions, as well as for the structured design of entire facades and roof structures when it comes to that to allow certain places to light, such as. B. also with studio glazing and roof ends over stairwells and galleries.
  • the desire to use mineral glass plates preferably insulating glass plates, in which two or more mineral glass plates are separated from one another and sealed together by gaps instead of plastic plates.
  • the insulating glass described above has a basis weight of 30 to 35 kg / m 2 when using two mineral glass plates with a thickness of 6 to 8 mm, so that the maximum plate dimensions are limited for reasons of transport and handling during assembly.
  • the sprouts mentioned have the unpleasant property of forming a kind of retention basin for the water even after a downpour, which is limited on the sides by the rafters.
  • the rainwater generally contains more impurities the lower the amount of rain.
  • FR-OS 2 507 648 discloses a roof structure of the type specified at the outset, but in which a reliable seal against rainwater should normally be present.
  • the cited document only deals with the discharge of accidental rain and condensation water. If the known roof construction functions properly, the problem is solved in any case, the solution of which is addressed with the present invention: the dreaded dirty edges are formed.
  • the known solution when laminated glass panes are used today there is a considerable risk that their indispensable sealing on the bottom edge in each case will be destroyed by the penetrating rainwater, especially since the “drainage channel” formed is also not vented.
  • a roof structure is known from DE-GM 83 16 570, in which the rainwater should not penetrate into the supporting structure consisting of hollow profiles, the so-called “supporting structure”.
  • the solution given is only suitable to a very limited extent to avoid dirty edges. This is because both the pipe parts intended for drainage and the sealing strip in which the pipe parts are arranged must have finite wall thicknesses, and that the bevels in the region of the inlet edges of the pipe parts cannot be made arbitrarily pointed. The amount of non-draining water necessarily increases the flatter the roof pitch.
  • the invention is therefore based on the object of specifying a roof structure of the type described in the introduction, in which any backwater or any accumulation of water on the inclined transparent plates and thus the removal of impurities and the formation of incrustations is excluded without this in the internal drainage channel of the horizontal profile rails can penetrate into the room in which the sensitive connection points between the individual glass panels of insulating glass are located.
  • the object is achieved according to the invention in that the drainage channel is in constant communication with the overlying plate top via at least one defined gap-shaped inlet opening and in that the lower edge of the respective upper plate is connected to a wall surface of the drainage channel via an adhesive strip .
  • the top of the plate in question runs continuously and at least in places seamlessly into the drainage channel, so that there is no barrage, a retention basin or the like for the water.
  • the at least one inlet opening can be formed by lining up slit-shaped inlet slots, which are formed by sections of elastomeric sealing profiles which are used to fix the plate at intervals in the profile rail.
  • the dimensions of the inlet openings or the gap width is expediently chosen to be smaller than the cross-section of the drainage channel, so that coarse contaminants such as leaves, branches, etc. are retained, smaller contaminants that can pass through the inlet openings, but easily through the drainage channel (and downstream Channels) can be dissipated.
  • the adhesive tape ensures that the water is led over the lower edge of the plate, and can not penetrate into the space in which the plate is supported against the rung and in which the sensitive joints between the individual glass sheets of the insulating glass are located .
  • Such a profile can be composed of conventional profile parts, as will be explained in more detail using an exemplary embodiment.
  • the plate edges abutting and parallel to the horizontal profile rail (rung) are each covered to a sufficient extent by the end profile rail or by the holding profile rail, so that the interconnected edges of the insulating glass pane are under no circumstances affected by the UV radiation can be taken. This is particularly important because the processing guidelines of the glass manufacturers stipulate that the relevant panes or plate edges must be protected accordingly.
  • the main planes of two plates abutting the horizontal profile rail from above and below lie in a common plane (FIGS. 1 and 2), or that the main planes mentioned run at an obtuse angle to one another (FIG. 3).
  • the construction method described last is preferably used for pavilions or so-called galleries, the cross-section of which is in principle a polygon.
  • first rails 1 and 2 which run in the direction of the slope and represent the so-called «rafters». These first profile rails run continuously within the section shown. Outside the cut-out there are further first profile rails, all of which run parallel to one another. Between the first profile rails there are second profile rails 3, 4 and 5, the so-called “rungs”, along a horizontal line.
  • Plates 6 and 7 are inserted between the above-mentioned rails, specifically the plates 6 are referred to as upper plates and the plates 7 are referred to as lower plates with respect to the second rails 3 to 5.
  • the gradient (in the direction of line II-II) is, for example, between 15 and 30 degrees.
  • FIG. 1 In the middle of FIG. 1 it is shown what happens when the horizontal profile rail 4 forms, together with the inclined profile rails 1 and 2, a retention basin for rainwater 8, which is accumulated in a wedge shape. After this rainwater has evaporated, a dirt rim 9 usually remains.
  • FIG 2 now shows on the basis of the second profile rail 4 how it is possible to prevent the backwater of the rainwater 8 and the dirt edge 9 in Figure 1: in the profile rail 4 (and equally naturally in the profile rails 3 and 5) there is a drainage channel 10, which is connected to the top 11 of the plate 6 located above the profile rail 4 via an inlet opening 12.
  • a drainage channel 10 which is connected to the top 11 of the plate 6 located above the profile rail 4 via an inlet opening 12.
  • One of the two outlet openings 10a is located on the rear end of the profile rail 4 and is only shown in broken lines.
  • the outlet opening 10a leads into the inclined profile rail 1, in which there is of course a further drainage channel, not shown here.
  • the inlet opening 12 is formed by a parallel gap running the length of the horizontal profile rail 4, the gap width “s” being smaller than the width of the drainage channel 10 and the inlet 13 leading to this drainage channel. In this way it is ensured that coarser impurities are prevented from penetrating into the drainage channel 10, but that smaller impurities which have penetrated, however, can flow off without hindrance.
  • the horizontal rail 4 consists of a thermally insulated composite profile. This is formed by a lower profile part 14 and an upper profile part 15.
  • the lower profile part 14 has on its two longitudinal edges 16 and 17 grooves 18 and 19 for the form-fitting mounting of elastomeric sealing profiles 20 and 21, which in turn serve as a support for each of the plates 6 and 7.
  • the upper profile part 15 is connected to the lower profile part 14 via two heat-insulating spacers 22 and includes the drainage channel 10. Furthermore, the upper profile part 15 below the drainage channel 10 has an extension 15a, on which a drainage channel 10 and the lower edge of the upper plate 6 covering the end profile rail 23 is inserted by a so-called clip connection.
  • This upper end profile rail 23 has at its free end two unspecified projections which determine the dimension “s” of the inlet opening 12 and between which there is a groove 24 into which a further sealing profile, not shown here, can be inserted.
  • This sealing profile should (if present) not close the inlet opening 12. Rather, the sealing profile in the form of short sections and at a distance from each other in the Groove 24 used so that a sufficient fixing of the plate 6 is possible without unduly blocking the inlet opening 12. As already said, it is sufficient that the residual water can drain off in a short time after the precipitation has ended.
  • a holding profile rail 25 covering the upper edge of the lower plate 7 is inserted at the bottom by means of an analog clip connection.
  • This retaining profile rail 25 contains a further sealing profile 26 in a corresponding groove, by means of which the retaining profile rail is supported on the edge of the plate in a well-sealing manner via the sealing profile.
  • the wall thickness of the adhesive strip is exaggerated; in practice it does not markedly narrow the dimension "s" of the inlet opening 12.
  • the rainwater runs off the top of the adhesive strip 27 without having the opportunity to penetrate into the space 28 below, in which the connection points of the plate 6 and spacer blocks 29 are located, which absorb the thrust of the upper plate 6 and are against corresponding, Support unspecified projections of the profile parts 14 and 15 without hindering the ventilation of the joints of the plates.
  • the lower profile part 14a is of subdivided design, and in the region of its longitudinal edge 16 there is an insert profile 30 which essentially has the shape of an “L” in cross section and can be positively connected to the profile part 14a.
  • a corresponding groove for the sealing profile 20 is in the present case in the insert profile 30, so that this is reliably held within the profile rail 4a by the bearing weight of the plate 6. Details are shown in Figure 4.
  • the spacer blocks 29 are also present here.
  • a side wall of the drainage channel 10 is formed there by the upstanding leg of the insert profile 30, which is inserted or snapped tightly into a groove 14b of the profile part 14a.
  • the selected distances maintain the thermal resistance of the entire profile .
  • the adhesive strip 27 is connected to the leg of the insert profile, the side wall of which simultaneously forms the one wall surface of the drainage channel 10. In this way, the rainwater is conducted over the room 28 analogously to FIG.
  • the attachment of the adhesive strip 27 is also explained in more detail with reference to FIG. 4.
  • the first profile rail 1a has a correspondingly bent course.
  • the adhesive tape can be a self-adhesive metal foil or a self-adhesive ceramic fleece which is provided with a protective foil in the manner specified.
  • Such long-lasting adhesive tapes are commercially available today.
  • FIG. 4 shows the insert profile 30, one leg 31 of which has the groove 18 for receiving the sealing profile 20, not shown, and lugs 33 and 34 for a clip connection with the groove 14b of the lower profile part 14a (FIG. 3).
  • the adhesive strip 27 In order to be able to attach the adhesive strip 27 easily, its protective film 27a or 27b is made divided in the region of the later kink (dividing line 27c). The adhesive strip is then attached if the end profile rail 23 and plate 6 are not yet present, by first removing the lower part 27a of the protective film and the adhesive strip 27 over part of its width with the inner wall surface of the drainage channel, ie. H. is connected to the upwardly projecting leg 32, the plate 6 shown in broken lines is then placed (using spacer blocks 29), the upper part 27b of the protective film is removed and the adhesive strip 27 is also folded down in the direction of arrow 35 with the lower edge the plate 6 connected so that the rectangular configuration of the adhesive strip 27 shown in Figure 3 results.
  • the adhesive coating is indicated by the dotted areas.
