Abstract

The support has arms comprising fixation profiles at respective ends with two edges. One of the edges is formed as a sliding edge for spacing the arms at the time of passage of a flange that is placed under roof modules (3). The other edge blocks the profiles against a receiving part located on the flange. An opening (6) is provided for passage of a fastener i.e. nail, toward a frame (4) or under a cover. A base plate (25) carries a coolant system i.e. tube (2), in an inner surface to block the coolant system against the flange. An independent claim is also included for a method for fabricating a support.

Description

The present invention relates to a versatile fastening support for laying solar thermal recovery modules.

The invention mainly relates to a support for the production of roofs, but also vertical walls and decorative walls.

The present invention further relates to a method of manufacturing the support.

To fix this set and to make the sensors, the network and the frame or framework, solid, different modes of fixing have been developed.

Some manufacturers use mounting devices enclosing the network inside a kind of opening in the thermal recovery modules.

The heat-carrying tube is blocked between two recuperating elements. The state of the art is known from US 4319437, US 4204520, DE 2853287 and US 4086913.

Others block the heat pipe on a platen, allowing thermal transfer with the recovery module, as shown in DE 3026217.

These different fastening systems have one or more of the following disadvantages. Often, the mounting technique of the network imposes a specific type of solar collector whose aesthetics is incompatible with the realization of a roof of traditional appearance. For most systems, the clamping of the network against the heat recovery element does not allow to add a fixation on the framework. This requires another device for its attachment, such as a platinum, which increases the cost.

The mounting time is increased and may in some cases be a deterrent due to the tightening of many fastening collars. Another technique proposes a heat exchange panel intercalated on the underside of the roof. This system requires separate fasteners. It also imposes constraints for the immobilization of the elements of the cover itself, often called outer facing.

These intermediate recovery elements fail to increase the roof, increase the manufacturing cost and energy consumption for their production, while requiring additional exposure time for the apparent part.

Another system proposed by the patent filed under the number FR 2.935.172 makes it possible to maintain a traditional aesthetics of roofs and to overcome the aforementioned disadvantages, but has other disadvantages. Two features make it possible to keep the tube in contact with the roof modules.

Bosses located on the module recovery tiles block the tube and promote thermal transfer between the network and the module. A piece of support fixed on the frame under roof face positions the network. This piece is in the form of a hollow flange receiving within it the recovery network. These two devices have several disadvantages. Bosses are expensive to produce. They are not achievable by molding and require additional intervention in the production process.

The consequence is an additional cost of roof modules that is not compatible with the project economy. The interlocking of the network on the module is difficult because of a significant friction of the tube on the recovery profile, which causes a difficulty of pause and the frequent breakage of the elements.

The positioning of the bosses is imprecise and associates approximately with the diameter of the network.

In the case of a roof realization with modules having no embossing, the contact between the tile and the heat transfer network is affected and the thermal efficiency is reduced. - Regarding the holding part which takes the place of support, its size is difficult to control because of variations in ribs in the realization of the cover and in particular the frame. And by the inaccuracy of the thickness caused by the installation of a reflective material.

This inaccuracy is increased by the use of an insulating or reflective material consisting of variable thicknesses during the compression of the holding piece and mounting battens on this material. Another disadvantage is the fixing of the thermal recovery module by a nail or a screw, which causes an additional break time.

The purpose of the device according to the invention is to fix the thermal recovery module by overcoming these disadvantages.

It completes by improving the patent filed under the number FR 2.935.172.

To this end, the subject of the invention is a novel fastening device for the thermal roofing modules 20.

It allows better contact between the heat transport network and the thermal recovery modules.

This device ensures the reliable connection of the components of the cover, the frame and the solar thermal collector.

Finally, this innovation extends the use of thermal recovery modules to other roofing styles or for the realization of walls and walls.

The support according to the invention consists of a base which includes a location for the passage of the attachment to the frame. It is positioned on the frame of the roof is usually maintained by screws, lag bolt, nail or rivet borrowing this passage. This base is extended by a minimum of two arms located in opposition, separated by an interval, allowing the insertion of the heat transport network therein.

This base is positioned on the frame or frame and carries on its inner side the heat transfer network, blocking it in opposition of the thermal recovery bead located under the module. According to an advantageous characteristic of the innovation, the base accommodates a cradle at the inner part of the support, which laterally blocks the conduit in front of the receiving part of the bead located under the thermal recovery module. The installation of the modules is made simpler, the network does not lock on the outer edges of the bead. This cradle may be a constituent part of the support.

It may also be in the form of a selected insert and positioned later. This allows a greater flexibility for example for the selection of a different network diameter, in connection with the use of heat transfer fluid, or for the adoption of a more insulating material for a thermal break with the roof. It is also possible to use an insert which has a higher elasticity which has the characteristic of maintaining the heat transport network against the thermal recovery bead in the manner of a spring. This also makes it possible to reduce the production cost of the support, since only one type of support is necessary for several heat transfer network diameters. This thermal break in the frame, according to the use of the invention, may also be carried out for the benefit of a wall or building.

According to other features of the invention, the arms in mutual opposition comprise at their ends hooking or anchoring profiles dedicated to the attachment of the modules.

The profiles come into contact with the bead located on the underside of the module. This causes the bending of the arms located on both sides. The profiles bear against the heat recovery beads facing them which constitute an outgrowth of the module and slide on at the time of assembly.

The inner face of the bead touches the network and compresses it into the final position. The profiles block the roof modules on their bead by one of the edges of the profile and by the friction caused by the pinching of the arms in opposition. For this purpose, the profiles positioned at the end of the arm have two categories of edges characterizing its use.

The first type of edge allows the sliding intended for the spacing of the arm at the time of passage of the bead located under the modules.

The second type of edge ensures the attachment or anchoring, it is blocking the profile against the receiving zone located on the bead of the module. The specificity of the edges and their impact on the binding does not depend on their shape which can be varied, but angles constituting them with respect to the arm as well as the nature of the bead provided opposite.

The axis perpendicular to the arm defines the function of the edge between sliding and hooking anchor explained in Figure 10.

To ensure the function of the support, at least one arm has at its end a fixing edge. Indeed according to particular embodiments of the invention, one or more arms may comprise only sliding edges opposing one or more arms performing the attachment or anchoring.

The receiving zone located on the beads of the thermal recovery modules is determined by the type of profile concerned at the end of the arm and the choice of fixation:

-For imprints intended to receive the male profile by a female form qualified as a hooking zone. -It is an area whose hardness lower than that of the profile allows anchoring on the bead.

Following the insertion of the module on the support, the arms are spread apart. The contact of the heat transfer tube and its compression limit the depression of the module to the proper position. The profiles at the end of the arm are anchored or hooked on the bead in this position. The network is then held tight in compression on the thermal recovery profile. This tightening is all the easier as the elasticity of the network is adapted.

The innovation thus meets the objective of a good thermal transmission achieved by the close contact between the network and the bead located under the thermal recovery module.

According to a particular embodiment, it is appropriate to use a heat transfer network flexible or qualified semi-flexible, such as crosslinked polyethylene, which will allow a better network voltage with the module.

The fixing by anchoring of the profiles benefits from the reaction to the crushing of the network and adjusts the position as close as possible to the contact. The heat-transfer tube is thus sufficiently in contact with the module to avoid the use of the delicate embossings to manufacture. Fixing by anchoring is carried out thanks to the reaction of the tube which blocks the profile on the softer zone of the bead located under the module. According to another embodiment of the invention, the fixing of the module is carried out by hooking. Fastening by hanging is perfectly adequate thanks to a sufficient number of indentations located on the thermal recovery profile of the roof modules.

The minimum of an impression is necessary to fix the modules by hanging.

According to an advantageous characteristic of the invention, several indentations will be positioned parallel to each other, allowing progressive tightening by progressive snapping of the profiles.

Each attachment profile located at the end of the arm or in its vicinity, faces a dedicated attachment zone, located on the bead of the module. One of the footprints of this zone allows the attachment edge 15 immobilization support of the module.

This attachment zone comprises either: One or parallel fingerprints of identical female shape to the male profile with a slightly larger dimension. - One or more imprints that have a geometric shape different from that of the male profile. They also have a larger dimension making it possible to interlock and hold with the hooking edge.

The slightly larger dimension of the hollows or imprints allows a good interlocking of the profile on the one that faces it. By increasing the width of the cavities, an adjustment of the position of the module on the support is possible and facilitates the displacement caused by the expansion. With its fingerprints, the support according to the invention makes it possible to bring the heat transfer network into close contact with the thermal recovery modules of the roof thanks to a gradual tightening.

This ease of adjustment contrasts with the lack of flexibility caused by the use of fixed pins. In addition, the possibility of adjustment offered by the innovation overcomes the difficulties caused by the use of a holding part, the dimensions defined in advance when laying on the frame. Otherwise this room would not compress the network regularly.

This system also makes it unnecessary to add the complementary fixing of thermal recovery modules often located at the top of the module.

According to another characteristic of the invention, the fixing device in the context of its use in the upper part of the module is substituted for the usual cleat for mounting. This allows for savings in materials and assembly time.

Indeed, the cleat which usually provides the function of fixing the modules on the frame, is advantageously substituted by the device according to the invention which constitutes a fastening profile usable on all cover sections. Thus, the fastening device makes it possible to perform and to satisfy the following minimum functions:

Ensure the fixing of the roof modules on the frame. 5 Receive within it the heat transfer network for thermal recovery transmitted by the bead in the underside of the modules. Allow lateral positioning of the network by means of a cradle in order to facilitate the installation of the modules. Ensure a precise tightening of the module against the heat transfer network for a good thermal exchange. Correct the dimensional inaccuracies related to manufacturing variations of the various components of the roof such as the frame, the roof modules, the diameter of the network, the installation angle of the modules ... 15 Fix the modules in all directions by making possible a displacement for the dilation. Resist the forces of wind and gravity on each individual roof module.

According to particular embodiments: the retaining arms of the fastener located laterally have slots which leave alternating place to parts free of arms. The number of arms per support then exceeds two.

The alternation of these holding arms with gaps forming the slots is possible regardless of the type of profile carried on the arm.

At the time of insertion of the module, the narrowness of the arms facilitates their flexion.

According to a particularly advantageous mode of innovation, in the case of use of the attachment profiles, the insertion of the attachment profile on the recessed module area can be done at different levels. For example, the hooking profile located at the end of the arm can be positioned on the second hollow encountered during the tightening maneuver of the tube, while the next arm will catch in the third hollow. And this, given a certain clearance between the hooking profile located at the end of the arm and the female footprint located on the bead.

This game is defined in that the female footprint is of a dimension slightly larger than the male profile.

Thus, variations of dimensions on the frame, the network or the module can be compensated quickly by successive clicks, providing a great flexibility of adjustment over the entire length of the support.

The discontinuities of the cover support, such as the flatness defects of the variations on the slope of the modules, can be corrected.

According to particular embodiments: Each support arm of an attachment profile taken individually corresponds to a zone for attachment located on the bead of the module. This recessed area located longitudinally on the profile of the module gives way to solid areas.

The axis of the supporting arms of these profiles and the axis of the impressions correspond as well as their alternations.

According to a particularly advantageous embodiment of the invention, the distance between the axes will be constant over the entire length of the bead and the supports.

The alternation of the slots formed by the arms makes it possible to shift the module of one or more sets of cavities or recesses on the bead. The narrowness of the arms and the increase of their number make it possible to shift them more finely along the bead. As before, the dimension of the impressions is greater than that of the profiles to allow mounting. To facilitate the adjustment, it is interesting to further increase the width of the impressions relative to the width of the latching arms. As this edge is accentuated, it allows a translational movement of the modules. This translation is strictly limited by the locking of the attachment profile located at the end of the arm on one of the two ends of the impression.

Consequently, the possibility of translation of the module on its support is framed by the delta between the two ribs constituted by the width of the arm and the width of the footprint.

The advantage that results from this characteristic is a greater flexibility of assembly, as well as the possibility of small movements related to the expansion of the materials. These characteristics are particularly useful in the context of the realization of a roof to limit the movements during the assembly and to face the strong variations of temperature.

The displacement of the roof modules on the support is strictly blocked by the profile of the arms abutting the lateral ends of their respective fingerprints.

The blocking of the module on its support is furthermore favorable to the use of thermal recovery on blankets having a bead in the direction of the slope.

Indeed, thermal recovery modules whose beads are arranged in this way are held in position and do not fall. This feature makes it possible to use the invention as a single attachment for the roof modules in the form of channel tiles and related like Provençal or Roman tiles on the so-called cover part (having the convex part upwards). According to a particular embodiment, the support comprises one or more orifices intended for the passage of links or collars allowing the presentation and the maintenance of the heat transport network before the installation of the modules. These orifices are placed under the cradle for holding the tube, or may also be placed in the base to exit on either side of the tube. The link or the clamping collar of the heat transfer network located around it is not impeded by mounting by the recovery bead, given the discontinuity that exists in the underside of the module. The bead-shaped profile that allows thermal recovery and transfer by conduction to the heat transfer network is not present under the entire surface of the module (this for example at the level of the tiles under the lateral overlap area).

If necessary, it is possible to undo the fastening links as and when the realization of the roof. These links or collars then become temporary and allow the presentation of the network at the time of fitting by fitting of the thermal module. The positioning of the network is done by the installation of the previous modules.

According to another more advantageous embodiment of the invention, these links or clamps can be replaced by a narrow piece for blocking the tube whose object identical to the link allows the positioning of the network before laying the modules. This piece has a location for receiving the heat pipe. This location located in opposition, maintains the tube in all positions on its support before the installation of the modules.

It takes again the function devolving to the cradle by blocking the tube laterally and possibly makes it possible to replace it.

The holding piece hangs on the end profile of the arms in the same way as the bead under the module. It correctly positions the heat transport network in order to nest the profile located on the thermal recovery module.

As previously this narrow piece can be removed at the time of installation modules.

According to another embodiment of the invention, an orifice positioned in the hollow of the cradle allows the positioning of nails, screws or rivets necessary for attachment to the frame. Since the fastener must not oppose the correct positioning of the tube on its cradle, the part at the fixing head will be positioned below the level of the tube with a bowl of sufficient size. On the other hand, the orifice may be offset from the cradle or the axial position to be placed laterally in the bottom of the support -12- constituting the base, without discomfort for the network, under the same conditions namely to have a sufficient bowl.

The orifice and the joint attachment according to another embodiment can also be made at the time of execution of the construction site and the installation of the support on the roof, forcing, striking or using cutting tools or drilling like a drill.

According to another advantageous characteristic of the invention, the cradle may consist of an insert positioned at the bottom of the support for receiving and laterally blocking the heat transfer network.

The material used for this part may be different from that of the support, with improved characteristics in terms of thermal insulation.

This piece allows a better rupture of the thermal bridge responsible for loss of the heat transport network through the base to the frame. This thermal break that benefits the heat transfer fluid in the network improves the recovery performance and economic performance of the whole.

This piece can also have enhanced elasticity qualities, which has the effect during tightening of the roof module to further maintain in compression the heat-transfer tube against the inner face of the module recovery bead.

Another advantage is the possibility of changing the module and the diameter of the tube, after the installation of the support on the frame. The attachment used for the support towards the frame can also allow the maintenance of this insert provided to cross it.

According to another characteristic of the innovation, the support can be fixed directly to the building or the masonry via the ordinary fixing which passes through the base of the support. This allows for vertical walls or decorative walls. In some cases, a wooden frame may be retained on the wall to create or improve a thermal break between the support and the modules. In its use, this frame is similar to the frame or the frame of the roof. According to particular embodiments: the arms for holding the support may have a zone of lesser thickness intended to facilitate the bending at the moment of sliding passage of the bead of the modules on the profile.

According to another characteristic of the invention, the hooking profile located at the end of the holding arm may have a rounded gripping edge or flanges, the angle of incidence of the edge allows disassembly of the module by negotiations. This angle of incidence and this shape must be adapted so that the pinching of the arms sufficiently holds the module in position against its heat transport network. In particular, that the reaction caused by the elasticity of the heat pipe at the time of assembly, as well as the expansion and external climatic stresses, can not dislodge the profile of its footprint. According to a particular embodiment of the modules, the bead can receive a surface treatment at the location of the receiving zone of the fastening profile, in order to locally improve the mechanical characteristics for sliding, anchoring or snapping. For example, to facilitate the sliding of the profile with a Teflon surface treatment or, on the contrary, to offer the fastening profile a more ductile material for its anchoring. This is achieved by plastic deformation of the surface material.

According to another characteristic of the invention, some arms of the support may have an absence of fixing edge. Their function is then limited to the sliding of the module and the pinching thereof in front of an arm comprising a fixing profile.

An asymmetry of the arms positioned on the support, in the case where they exceed the number of two, is also possible, provided that this asymmetry is taken into account by the thermal recovery modules for their fixing by a correspondence of the zones. for hanging or anchoring on the bead.

According to another particular embodiment, the anchoring profile may have a raised portion added to the arm of a hardness greater than that which is present on the beads located under the module, to allow the good insertion of the profile in the material of the bead. This anchoring is then achieved by friction or deformation -14- or micronization or morcellement. The production cost of the thermal recovery modules can be limited since an implementation of anchor impressions is not necessary. Nevertheless, the quality of the anchoring, the ease of installation and possibly the disassembly are affected.

According to a variant of the innovation, the base of the support can be widened and deepened. The base can extend laterally on each side of the arms allowing for example the offset installation of the attachment to the frame. To facilitate, for example, laying the nail support by the shift of the hammer strike on a less sensitive area with no cradle or arm nearby.

According to another particular embodiment of the support, the base is modified and takes the form of a constituent part of the frame. The base of the support is modified in its dimensions. It may be deeper, wider, or changing shape. The support thus accumulates the function of a structural part. This variant embodiment allows simplification of realization of the roof. For example, deeper, the support replaces the cleats of the covers in the style of ordinary flat tiles or mechanical tiles. According to another choice, it is given the shape of the triangular chevrons or cleats usually used for the realization of tile-channel style roofs by deepening, and widening the face of the base in contact with the framing failure. This retaining all the advantageous features of the support.

This enumeration of the cleats and chevron is not limiting. The change of the shape of the base allowing it to replace all constituent parts of the frame.

According to another variant of the innovation, the base of the support can be traversed by openings allowing ventilation on both sides. These orifices provide a passage to the air and allow aeration. This natural ventilation is intended to remedy condensation on the underside of the roof and meet the regulations for minimum ventilation in the roof.

The accompanying drawings illustrate the invention and provide a better understanding of its operation. FIG. 1 represents a roof section on which thermal recovery modules are arranged taking the appearance of ordinary tiles of flat tile style.

Figure 2 shows the section of the roof section of Figure 1 according to AA '. It makes it possible to distinguish on the underside of the modules the various elements including the fixing device according to the invention. FIGS. 3a, 3b and 3c illustrate different stages of the assembly of the different elements at the level of the section BB '. Figures 4, 5, 6 and 7 show a section delimited by sections BB 'and CC' of Figure 1, the elements were separated before assembly to better represent their specificity.

Figure 10 shows a variant of the invention consists of an arm which has a projecting portion attached to the arm of high hardness. FIGS. 11a to 11i illustrate different variants of the holding profiles whose characteristics are broken down into three families illustrated by FIGS. 12 to 14.

Figures 12 to 14 illustrate the operation of the attachment according to the three types of profiles located on the holding arm, or by hooking. Or by anchoring, with or without possibility of dismantling. FIGS. 12a to 12d show the basic profile allowing blocking by one-way clipping of the module on its support.

FIG. 17 shows a variant of the support whose enlarged lower base makes it possible to substitute it for the chevron in the context of its use with modules in the form of a covering channel tile. The set is here fixed with lag bolts.

Figure 18 shows the support positioned on a truncated chevron.

Figure 19 illustrates the use of the support on a corrugated under-roof in the economic coverage frame. The support is here fixed by rivet.

FIG. 20 illustrates another use of the support at the top of thermal recovery modules, thus making it possible to substitute them for the cleats ordinarily necessary for their fixing.

Figure 21 shows a support whose base allows a remote attachment to the frame.

Figure 22 shows a broad view of the use of the support with a corrugated under-roof. Referring to these drawings, I have shown in Figure 1 a roof pan on which thermal recovery modules are arranged taking the appearance of ordinary flat tile style tiles. These modules are commonly made of terracotta. The external appearance thus remains totally identical to that of an ordinary roof tile, since the entire recovery portion is located on the underside of the roof, invisible from the outside. Nevertheless, these modules can be made of other materials, for example glass or certain plastics. The solar heat recovery module (3), often simply called module or tile, is fixed using the support (1) object of the innovation in which is inserted the heat transport network (2). The support (1) is fixed on the frame (4) by the piece (5) here a nail. A cleat (19) in the upper part provides additional support which relieves the arms (9) of the support (1) of the constraints of rotation exerted around the pivot centered on the tube (2).

These cleats (19) may advantageously be replaced by recuperating supports as shown in FIG. 20.

Figure 2 shows the section of the roof of Figure 1 according to AA '. It makes it possible to distinguish on the underside of modules the different elements whose support according to the invention. The fixing support is positioned on the frame (4) consisting of a floor of rafters on rafters covered with a reflective and insulating multilayer screen. The thickness fluctuations of this screen cause variations in the position of the module. These fluctuations in thickness are not shown in the drawings, but are present in practice. These fluctuations can be compensated for by different positioning of the module on the support as illustrated by the following figures in contrast to an ordinary single thickness support. The variations of the thickness are not the only ones likely to be corrected by the support. The angle of inclination of the modules is indeed variable depending on the position of the module located lower below. This position depends on the spacing of the cleats (19) which determine the useful section of the module.

Figures 3a, 3b and 3c illustrate different stages of the assembly of the different elements at the BB 'section. These figures make it possible to better understand the possibilities of adjusting the module on its attachment as well as its operation. Figure 3a shows all the elements before assembly. The support consists of a base (25) extended by arms (9) in opposition, the inner portion comprises a profile (12) for fixing the thermal recovery modules 5 (3). The entire support is immobilized on the frame by means of an ordinary fastener, such as a nail or a screw (5), passing through a hole (6) the base of the support (25). The positioning of the orifice (6) allowing the fastener (5) to pass in the axis of the support is not a necessity and can be offset laterally. The only constraint is to cross the base and the attachment (5) does not interfere with the passage of the heat transport network (2) in the required position. The fastener (5) passes through these figures 3 the cradle (10) and the base (25). The orifice (6) for fixing may be made by force directly at the time of implantation of the nail or the screw by a hammer or using a rotary tool. The cradle (10) makes it possible to position the network (2) laterally opposite the bead of the module (13).

On the other hand, it will be easier for the mounting that the support is pierced from the beginning so as to guide the attachment to the most favorable location and to favor its implantation on the site.

According to one embodiment, a small bowl will be made by countersinking to receive the head of the binding whatever its shape and allow the passage without discomfort of the network.

Thus, the location between the arms (9) allows the passage and positioning of the heat transport network (2) on a cradle (10) positioned on the base (25) for preventing lateral movement of the tube on its support. The head of the nail or screw is embedded in the orifice (6) leaving the cradle (10) free from any outcropping. The heat transport network is then positioned within it, maintained by a fastening link (8) ready to receive the thermal recovery module (3). The link or clamp (8) keeps the network in position on the support prior to the installation of modules, as the retaining piece (24) 2966228 -19- presented in variants thereafter. These elements can be left on the network, because the bead (13) located on the underside of the thermal recovery modules has discontinuities on the lateral overlap areas with the mechanical tiles, or at the edge of the edge 5 of the modules for others types of coverage. If necessary, the function of holding by the link, the collar (8) is only temporary. It can be undone as soon as the network is maintained by a roof module. The roofer positions the module (3) on its support and exerts a bearing pressure as shown in Figure 3b. The holding arm (9) is stretched by a lever effect, caused by the sliding of the bead (13) on the profile (12). The geometric ratio between the width of the arm and its height facilitates its flexion. The module (3) reaches the contact of the network (2). The pressure exerted on the module by the roofer meets the opposition of the network by contact against the tube of the inner part of the bead (13) present in module face Figure 3c. The profile (12) hangs on the roof module in the last cavity encountered on the zone (11), located on the bead of the module. The spacing of the arms at rest is greater than the width of the bead, which leaves the possibility of the anchoring profile to be positioned by slight pivoting differently on both sides of the module. The module is pivoted the heat transport network (2); it remains limited in the angular movement by the position of the arms (9) and their abutting contact with the bead (13). The attachment of the module on its support is not affected by this shift, the latter having a small incidence on the position of the profiles with respect to their fingerprints which allow a certain clearance. The nip constraints by the profile (12 ), located at the end of the arm and the position of the other modules on the roof, immobilizes the assembly in fine.

Figures 4, 5, 6 and 7 show a section delimited by sections BB 'and CC' of Figure 1, the elements of which were separated before assembly to better represent their specificity.

Figure 4 shows the section of the module, the network and its attachment.

Figure 5 shows a section of the support viewed in profile. This stretch is limited in size for the sketch. But according to some particular embodiments, the support will be several meters long in the manner of boots cleats used in coverage. The zone located on the profile of the thermal recovery module intended for the attachment (11) is delimited laterally by the dimension (a) whose width is greater than that (b) of the arms (9) located on the support. The respective axes of the indentations (11) and the arms (9) are separated by an identical dimension (c) so as to allow attachment to the entire support. The section BB 'CC' represents a section of the support which illustrates these spacings. This characteristic allows adjustment by displacement of the module (3) along the axis (Z) on the support in successive steps. More precise adjustment of the position of the modules is made possible by the difference in size between the arms (b) and the imprint area (a). The fineness of this adjustment on the Z axis depends on the spacing represented by the dimension (c). This adjustment will allow lateral shifting of the roof modules of the dimension (c) multiplied by an integer plus or minus a control delta relative to the difference between the dimension (a) and (b). In the case of roof taking the appearance of flat or mechanical tiles as shown in Figures 1 to 7, this will shift laterally to the left or right. Regarding the recovery modules taking the appearance of Provencal tiles, 20 as shown in Figure 17 it allows to shift the modules higher or lower.

Figure 6 shows the section of the fastener seen from above. The bowl is clearly distinguished from the orifice (6) intended to receive the fixation occupied by a nail (5) in one of them.

Figure 7 shows the cavalier perspective of the elements. The arms located on either side are ready to receive the profile of the module (3). Only two fingerprint areas (11) intended to receive the clipping profile (12) are visible. The others are hidden by the module (3). Each fingerprint area has five notches that allow adjustment by five successive notches. This amount of five notches is not a limit. It is quite possible to reduce or increase them by additional notches above or below all along the bead. These notches can be made by milling the bead. This one allows a great precision in their realization.

According to a particular embodiment of the innovation described in the following paragraph, it is possible to specify the nature of the materials used, a scale of dimensions and a method of manufacture.

Thus, the thermal recovery module (3) will be made by clay molding in the manner of ordinary tiles. After firing, the bead (13) of the module will receive indentations (11) by milling which will be achieved by a rectilinear movement of the module in coordination with the rotational movement of a tool with several edges. The accuracy of the prints can be of a very good quality. If necessary the bead (13) will be previously ground by machining. The support according to the invention (1) will be made of a plastic material by extrusion. The manufacturer realizing this transformation will qualify the support (1) in profile. This profile (1) 15 can then be modified by machining and cutting to remove some parts when it will realize for example alternating arm and armless slots. In the same way we will drill the orifices provided for the links or collars (7), for fasteners (6) or for ventilation (27). The support (1) will be about two to three meters long. The internal spacing of the arms (9) will be about four to five centimeters for an overall external width of five to six centimeters and a depth of the same size. The anchoring profile (12) will have a depth (E Fig. 9) of two to four millimeters. The cradle for the network will have a curvature corresponding to its diameter located at about 14 to 20 millimeters. This cradle may consist of an insert (17) made of polystyrene to improve the thermal insulation towards the frame. The tube (2) will be commonly made of semi-flexible crosslinked polyethylene. In the cover banks, the network (2) can perform a loop in the module sub-face. But if the support (1) was extended to the end of the cover, it would be possible to insert the network in one of the slots located between two arms. An arm (9) otherwise could be removed by cutting to promote the passage of the tube (2). The particular embodiment thus described is not limiting in the use of materials and dimensions. Thus, in other particular embodiments, it will be possible for example to use innovation for large modules or with a support (1) made of recyclable and more ecological materials such as some softwoods. The method of manufacture of the support would then be different and could for example be manufactured by the passage of routers on a cleat, then sawing and drilling the elements. The type of wood used for the realization of the support (1) may be common ash which is a resilient and very resistant wood. It was used formerly for the manufacture of skis because of its nervousness. This support could be completed by an attached cradle (17) see Figure 15h, 15i cork which allows to properly isolate the network (2) .du base (25).

Figure 8 shows variants at the holding arms (9). A zone of lesser thickness located on the holding arm (16) facilitates the bending of the arm (9). On the other hand, the profiles (12) have an asymmetry. One of the arms taking the one shown in Figure 11d, allows the sliding of the bead of the modules, the other arm located opposite or in opposition to its attachment. The module is held by pinching the arms and fixing one of the two sides by a fastening profile may be sufficient in some cases. The base (25) delimited by the location under the support surface and the base of the arms (9) is traversed at the time of installation by the fastener (5) in the form of a nail, screw, rivet or lag bolt.

FIG. 9 illustrates the anchoring and hooking profiles (22) and makes it possible to distinguish the characteristics of the locking protrusion (E) expressed by the angles measured from the arms of the support. The angle is between ninety degrees and one hundred and eighty degrees allows the sliding of the panel (21), the profile (12) on the bead located under the thermal recovery module and allows the spacing of the arm ( 9) of the dimension E which expresses the depth of the anchoring or hooking profile (12). The angle R makes it possible to define the quality of attachment or anchoring of the panel (22) located under the profile at the end of the support arm. For an angle (R) greater than or equal to 90 degrees, the attachment on the bead of the thermal recovery module is final. For an angle R less than 90 degrees, disassembly of the module becomes possible. For the anchoring of the module, an angle (13) greater than 90 degrees is required. The difference of the angles represented by a and 13 must be positive to allow the materiality of the fastening profile. The rating. (£) may not exist in the case of a sliding arm as shown in Figure 8 on the right arm. It even has a chamfer to facilitate the approach of the bead this is not the case for the left fixing arm which must have a dimension (E) positive.

Figure 10 shows a variant of the invention consists of an arm which has a raised portion reported high hardness as anchor profile. FIGS. 11a to 11i illustrate different variants of the holding profile, the characteristics of which are decomposed into three families illustrated in FIGS. 12 to 14. FIG. 11a has a three-sided profile, two of which are slidable and one of which hanging. FIG. 11b makes it possible to distinguish the two constituent zones of the profile. The curved shape is broken down into several tangents that take up the characteristics of the panels according to the angle formed with the arm. The axis GG 'at right angles to the arms delimits the two types of panels, here slipping and hooking. Figure 11c shows a profile whose pan (22) corresponds to either anchoring or hooking provided that the bead has corresponding sawtooth impressions (for example) (not shown). This profile does not allow natural disassembly. Figures 11d and 11h show a profile only for sliding and an opposing arm must have a fixing profile. Figures 11a, 11f, and 11g, have a pan (22) for attachment of the module and disassembly by traction. Figure 11e shows a pan (22) for the unmountable hooking of the modules. Figure Ili shows an arm (9) carrying a double fastening profile 25 indémontable (22) which allows the simultaneous attachment of the arm in two indentations located one below the other. This profile improves the fixation quality in difficult cases. For example for windy areas. The number of sections or edges is subordinated only to the presence of parallel prints in correspondence. In the same spirit, it is possible to increase the number of anchor edges on one arm. Several fastening profiles on the same arm are possible, the support remains characterized by arms (9) in mutual opposition, at least one provides fixation; this regardless of the number of profiles (12) it supports. The illustration Ili has a double hooking profile of which the other geometric shapes illustrated in FIG. 11 are compatible. As well as profiles with anchor edges or with anchors (20) figure10. Figures 12 to 14 illustrate the operation of the binding according to the three families of profiles on the holding arm. Level lines below these figures make it possible to judge the progression of the thermal recovery module towards the support. Each fixing profile has two sides. The first is the spacing and sliding edge of the arm (21): it will exert pressure on the support arm (9) located on the support at the time of depression of the module (3). The second is an anchoring or hooking piece (22) which allows fixation. In Figures 12 to 14, the arms (9) are truncated. Similarly for the modules (3) of which only a portion of the thermal recovery bead (13) is visible.

Figures 12a to 12d show the basic profile for hanging. Figure 12a shows the module positioned on the second notch in the tightening direction. The roofer puts pressure on the roof module and it sinks as can be seen on the level line DD '. The holding arm of the module flexes, Figure 12b to 12c by sliding on the edge (21) and the attachment profile is positioned in the third cavity located on the bead of the thermal recovery module. In the case of the illustration, given the angle of the pan (22) the thermal recovery module can only approach the support by a one-way lock (Figure 12d) as indicated by the gray arrows. The subsequent removal of the module is impossible without the deterioration of one of the elements or the voluntary separation by an external stress exerted on the arm located on the support.

Figures 13a to 13d show the profile with high hardness which allows its anchoring in the material of lower hardness. The bead of the module slides on the pan (21), while it approaches its final position. The reaction of the heat pipe on the module causes the anchoring of the profile by the incidence of the edge (22), (Figure 13d). This technique of fixing the support is particularly indicated with thermal recovery modules made of a soft material, for anchoring profiles of higher hardness and the difference between them angles a and 13 is low. See figure (9). In particular with an angle (3 approaching one hundred thirty degrees or for an anchor profile having a reported anchor and high hardness protruding part (20), for example metal, as shown in Figure 10.

Figures 14 illustrate a geometry of the anchoring profile for fixing the module while preserving a possibility of disassembly for a replacement operation or maintenance. The pan (21) allows the spacing (Figure 14b). The hooking edge (22) is positioned in the module on the third impression (FIG. 14c) as previously with FIGS.

The possibility of disassembly is made possible by pulling the module FIG. 14d because of its profile whose tangential angle to the curvature R of the panel (22) is less than ninety degrees (FIG. 9).

Figures 15 illustrate different geometries for the cradle receiving the heat pipe. In the case of Figure 15b, 15c and 15g the cradle is made recessed in the base (25) of the support. FIG. 15f shows a cradle offset from the axis of symmetry located equidistant from the two arms (9) to adapt to a recovery bead (13) whose network (2) would itself be offset from the axis of the bead. Figures 15h, 15i and 15j present an interesting variant of innovation. The cradle and made using a view of several inserts (17) made of an insulating material, elastic or both sets. This part breaks the thermal bridge that transmits the heat from the tube to the frame through the base (25) .In the case of an elastic piece, it reacts to the crushing of the heat pipe (2) in the now in compression towards the inner face of the bead (13).

All geometric shapes of the cradle (10) such as those of Figs. 15 are compatible with the use of an adjoining part (17). Figure 15j shows the blocking by a narrow part (24) of the heat pipe. This piece is very easy to position without tools by simply pressing on the support which facilitates the installation of the network (2).

Figure 15a also shows an alternative embodiment of the support (1) with an orifice (27) which passes through the base (25) providing ventilation of the underside of the roof. Figure 16a shows this perspective view. This ventilation also makes it possible to meet the requirements of the roofing regulations.

Figures 16a and 16b illustrate the holding part (24) for prepositioning the heat transfer tube. In these figures, the support consists of two unique arms placed in opposition. FIG. 16a comprises a cradle, which is not the case of FIG. 16b where the base on its inner face (25) directly receives the grating (2) and allows it to come into opposition with the bead. module (not shown). To block the tube laterally and facilitate installation, the cradle is replaced by the holding part (24), which carries out the lateral positioning of the tube before the introduction of the thermal recovery modules, and ensures its attachment to the support.

As for the link or the collar (8) mentioned above, the positioning function is temporary and the module then ensures the holding of the network. It is therefore possible to remove this part after the successive laying of the modules.

FIGS. 16c and 16d show several arms (9) separated by crenellated voids and also cradles integrated into the support. In the case of Figure 16d, the arms (9) are located in opposition, but are not exactly face-to-face without this is a difficulty in operation. In the context of clashing profiles, the imprints on the bead must take up this dissymmetry.

Figure 17 shows a variant of the support whose expanded base and the deep lower base allow to replace it to the chevron in the context of its use with modules in the form of tile cover channel. In this case, the support has a location for the attachment (6), intended for a lag bolt or a nail (not shown), to attach to a part of the frame (4), which here is a failure. The thermal recovery module (3) takes the appearance of a roof canal tile. The current tile (14) remains ordinary.

Figure 18 shows the support positioned on a truncated chevron. This variant of use illustrates the versatility of the support. Because it is the same support (1) that can be used for the realization of roofs with very different appearances, as it is the case here with the tiles channel compared to the flat tiles or the mechanical tiles. It will be possible to reduce the production cost of the profiles by the quantity production of a single model. Especially since adaptations from the same support (1) are possible by the use of an insert (17) fig. 15i and i being a cradle (10). The curvature or the shape of the internal face of the part (17), while maintaining the spacing dimensions of the arms (9), makes it possible to change the diameter as well as the positioning of the heat transport network (2). The insert 17 takes for this reason the geometric possibilities illustrated in Figures 15 relating to the cradle. FIG. 19 illustrates the use of the support on a corrugated under-roof in the economic roofing frame. The support (1) is then fixed by rivet (5).

FIG. 20 illustrates another use of the support at the top of heat recovery modules, thus making it possible to substitute them for the cleats ordinarily necessary for their fixing.

Figure 21 shows a support whose base (25) is widened. It allows another position of the attachment (6) to the frame (4). The head of the fastener (5) does not interfere with the network (2), it is simpler to use a striking tool to drive the fastener (5) without the risk of damaging the cradle of the support (10).

Figure 22 shows a broad view of the use of the support (1) with a corrugated under-roof (25). This technique makes it possible to produce more economical roofs with a Provençal appearance.

Other types of covers could be represented, responding to the desire to maintain an ordinary appearance while allowing the recovery of solar energy. The support according to the invention makes it possible to respond to numerous installation technical constraints. It facilitates the realization of roofs recovering solar thermal energy.

However, this invention is also intended to broaden the use of heat recovery modules over a wider range of cover styles such as those in the Provencal style, in canal tile or in the Burgundy style with removable modules taking the appearance of tiles. decorative glazes.

Due to the quality of the fixing, it is also possible to achieve walls 30 which, well oriented, recover the energy and that by protecting weather new or old buildings. These walls can also be decorative using modules of different colors reproducing a drawing or a work of art.

Finally, this innovation is intended to enable roofers to offer environmentally friendly roofing, using their know-how and their experience. 2966228 -28- It will make it possible to the greatest number a saving of energy, without giving up the comfort and the esthetics of the existing buildings. 5
