Description

COVERING DEVICE BASED ON PHOTOVOLTAIC PANELS, MEMBRANE AND SUPPORTS FOR ALL ROOFING
FIELD OF THE INVENTION The present invention relates to the field of buildings in which photovoltaic panels for the production of electrical energy from solar radiation are integrated.
More specifically, the invention relates to a covering device made from such photovoltaic panels within a roof, in particular using a membrane providing the sealing function.
PRIOR ART The installation of photovoltaic panels on the roofs of buildings, regardless of the type of building, is nowadays largely implemented, in particular because of the emphasis placed by the government authorities on the development described as sustainable and therefore, the use of non-fossil energy sources. Moreover, in some states, particularly France, the development of photovoltaic energy is encouraged by the purchase of the electrical energy thus produced under advantageous conditions, provided that said photovoltaic panels are integrated within the building and for example, within the roof, and therefore form a part of it.
In fact, many technological solutions have been developed to, on the one hand, ensure the fixing of such photovoltaic panels on the roofs, and on the other hand, meet the specifications set by the administration within the framework of this " integration ". Most of the time, however, there is a problem of sealing. Traditionally, this tightness between the photovoltaic panels and the roof structure is achieved by means of plates supporting said panels, said plates coming to overlap while being oriented so that their undulation is substantially parallel to the greatest slope of the roof. roof, as for example described in EP-1 310 747.
It has also been proposed, for example in document DE-20 2005 015455, another technical solution, consisting in sealing between the photovoltaic panels and the roof structure by means of a membrane covering the upper face of flat plates. underlying. To these flat plates, are fixed several profiles, each of which supports one or more pairs of adjacent photovoltaic panels. This solution is not satisfactory insofar as the installation of this membrane is a delicate operation, likely to alter the desired seal, especially at the fixing areas of the support profiles of the photovoltaic panels.
The present invention is part of a membrane roof to provide the sealing function.
SUMMARY OF THE INVENTION
The invention therefore relates to a covering device produced by the integration of photovoltaic panels, a synthetic membrane and a base ensuring the attachment of the cover on the structure of the roof and the attachment of the membrane.
According to the invention, the base is in the form of a linear section defining a receiving surface of said membrane, adapted to cooperate with a surface of complementary shape formed on another linear section, said upper section, secured to said auditory base profile, and ensuring the clamping of said membrane on the base profile, and provided with members adapted to receive, adjust, guide and fix the photovoltaic panels.
In other words, according to the invention, the membrane no longer remains completely under the panel fixing device, but just covers the base of said device, where it is maintained at this level like the punch principle - matrix to ensure sealing at this level, the punch being constituted by the base profile, and the matrix by the upper profile.
According to an advantageous characteristic of the invention, the base profile defines a hollow central portion capable of receiving a loop of said membrane or the two free edges of two adjacent membranes making it possible to join the membrane lays outside. common parts and ensuring optimized sealing and clamping.
According to a feature of the invention, the base profile may have on either side of the central portion, water discharge tubes extending along the entire length of said profile. Indeed, at this level, that is to say on either side of said central portion, the base profile can receive fastening elements of the upper section, encasing or enclosing said membrane, at which Sealing losses can occur even if the pressure between the base and the upper profile and the pressure between the fasteners of the base and the upper profile and the upper profile make them very improbable. In doing so, and assuming the occurrence of such a leakage loss, flowing water is received at the tubes and discharged to the ends of the roof.
According to another characteristic of the invention, the base profile may have a substantially semicircular cross-section, and in this case, the base of the upper profile acting as a matrix, has a shape also complementary.
According to a variant, this base section may have a substantially polygonal cross-section, the upper section again having a complementary shape. Other profile variants can be made on the same punch-matrix principle.
According to an advantageous variant of the invention, said upper profile has lugs projecting from either side of said central portion, adapted to cooperate with a female part 30 formed on the base profile, this cooperation being suitable to ensure the formation of the drop of water for the water likely to rise by capillary action, and thus to prohibit the loss of leakage that may result. According to an advantageous variant of the invention, said profiles have flats positioned on either side of the central portion of the base profile, suitable for optimizing the clamping of the membrane at this level and corollary sealing.
BRIEF DESCRIPTION OF THE FIGURES
The manner in which the invention can be realized and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments, given by way of non-limiting indication, in support of the appended figures.
Figure 1 is a schematic partial perspective view of the photovoltaic panel mounting device according to a first embodiment of the invention, Figure 2 is a cross-sectional view. Figures 3 and 4 illustrate a variant of the embodiment of Figures 1 and 2.
Fig. 5 is a schematic cross-sectional representation of a second embodiment of the invention.
DETAILED DESCRIPTION OF THE INVENTION FIG. 1 thus shows a first embodiment of the covering device made from photovoltaic panels, membranes and profiles according to the invention.
The integration of the panels and the membrane is basically carried out by two profiled elements, respectively a base profile 1 and a receiving section, of adjustment (orientation, height, inclination) and fixing of the photovoltaic panels proper 2, also referred to in the following description by upper profile.
The base profile 1, which can be better detailed on the sectional view of FIG. 2, firstly comprises a base plate 3 intended to bear on a roof element 30, sealing, thermal insulation or framing. It is therefore, in this case, plan. From this base 3 emanate two partitions 20, 21, extending perpendicularly to the base, and connected again to the base 3 by two substantially quarter-circle sections 22, 23.
It is therefore defined a volume profile, intended to receive a membrane 5, to confer the required sealing to the roof. This membrane, made of synthetic material, is for example PVC.
Between said partitions 20, 21, there is also defined a central volume or central portion 4, receiving a loop of said membrane 5, or, in the event that the mounting device is positioned at a connection zone of two adjacent membranes 32, 33, the free edges 34, 35 of said membranes (Figure 5).
The bottom of said central portion 4 receives a floor 7, pierced with through orifices, and implemented for the attachment of this base profile 1 above the material / carrier, in this case by means of screws 8.
According to the invention, the upper profile 2 has at its base 9 a shape substantially complementary to the shape of the base profile, as can be seen in particular in Figure 2. The membrane 5 is clamped between the base profile 1 and said upper section 2, the device of the invention being provided with means for fixing the upper profile to the base method, in this case by means of sealed rivets 10 fixed on both sides of the central portion 4.
The upper profile 2 has at the top of the complementary zone with the base profile, a slide 11, within which is slidable a plate 12 of corresponding shape, which can be moved freely by sliding according to requirements imposed by the dimensions of the photovoltaic panels 25 that the device of the invention is intended to receive. Said platen 12 is lockable within the slide 11 by simply tightening a bolt 13. It is furthermore secured to a U-shaped part 14 receiving the fixing means 15, 16 of the photovoltaic panel 25, and furthermore a groove 17 for adjusting the height of the receiving means 15,16 of the photovoltaic panel as needed. Said platen 12 can be inserted in the upper profile 2 vertically relative to the latter.
It is therefore conceivable, on the one hand, that the seal is safeguarded even though it happens by the cooperation of the base profile and the upper profile coming to grip the membrane (s) on the seal as a matrix.
Moreover, and according to an advantageous version of the invention, and shown in Figures 3 and 4, the base profile comprises on either side of the central portion 4 of the tubes 26, 27 defined on the one hand by the lateral partitions 20, 21 defining the central portion, on the other hand, by the floor 7 mentioned above, and finally, by the quarter-circle portions 22, 23, on which the membrane 5 is inserted. These tubes are likely to receive the water likely to flow in the attachment areas of the upper profile on the base profile, and allow its evacuation at the ends of the roof, said tubes extending for this purpose to the edge of the edge the roof.
According to another version of the invention shown in Figure 5, the cross section of the base profile and the upper profile is not circular as in Figures 1 to 4, but polygonal. It is thus defined a specific zone 28, 29 plane of cooperation of the base profile 1 with the upper profile 2.
In addition, in order to optimize the desired technical effect of optimizing the seal, one defines on each of these planar zones (in the embodiment of FIG. 5), or not (FIGS. 1 and 2), a recessed profile 30 and a projecting profile 31, intended, like the punch-matrix principle, to cooperate with each other, inducing additional tightening of the membrane 5 at this level.
These profiled elements are now advantageously derived from aluminum dies and therefore are particularly simple to achieve. They can also be made from any spinning or extrusion process in a simple manner. They thus make it possible to secure and integrate photovoltaic panels within roofs, including flat roofs, while preserving the watertightness, which could not be done efficiently or at a reduced cost to date. They therefore make it possible to have an integrated photovoltaic roofing system for any roof regardless of its slope and without structure recovery.
