Description

Title of the invention: Framing blade, kit and method for cladding a facade with simplified assembly for insulating a building Technical field

[0001] The present invention relates to the field of building facade cladding. The present invention relates more particularly to a facade cladding dedicated to the insulation of buildings, the assembly of which is simplified.

[0002] The present invention relates in particular to the framework of a facade cladding, that is to say the supporting structure of such a cladding.

[0003] The present invention relates more particularly to a frame blade for cladding the facade of a building having a simplified shape allowing both compact transport and simplified assembly.

[0004] The present invention also relates to a cladding of a facade covering, that is to say the exterior covering of such a covering, and to its fixing on a frame.

[0005] The present invention also relates to a kit for facade cladding comprising such blades and / or such cladding, as well as methods for facade cladding using these blades and / or this cladding.

[0006] The present invention will thus find numerous advantageous applications in the design and installation of facade cladding. Prior art

[0007] The Applicant notes that, in the field of building cladding, it is increasingly common to prefabricate the frame of the cladding before its installation, before fixing it to the building. Such prefabrication corresponds to an “off-site” assembly of the frame, as opposed to an “in situ” assembly corresponding to an assembly directly on the building, or close to it.

[0008] The frame is composed of a set of uprights and crosspieces, corresponding to vertical and horizontal blades or bars respectively.

[0009] The frame is generally made of wood or metal. The sections used for a wooden frame are commonly 45*145mm. The Applicant notes that, in the context of thermal rehabilitation of an existing building, the frame is used exclusively to receive insulation and to be covered with cladding, the cladding forming the covering of the facade. The sections commonly used are thus particularly oversized compared to their actual use. Such oversizing requires additional means for handling the various elements, increases material costs, and results in a higher carbon impact of the dressing, both because of the material used and the additional constraints.

[0010] The assembly of the frame, off-site and in situ, is thus a complex operation, which requires heavy tools, lifting equipment, and qualified personnel.

[0011] In the case of work carried out off-site, once assembled, the frame is transported to its installation location, generally by truck. Due to the shape of such a frame, corresponding to an assembly of uprights and crosspieces, it is extremely bulky compared to the actual quantity of material. The transport of this frame is therefore particularly complex. The Applicant thus submits that a truck transporting conventional frame walls can only transport a very limited number of frame walls, for example only 8 frames corresponding to the quantity necessary to clad two houses of a standard size, corresponding to the ground floor, one floor and the attic.

[0012] The Applicant therefore submits that there is currently no satisfactory alternative solution for carrying out the cladding of a facade, particularly in the context of new insulation and / or thermal rehabilitation, which minimizes the qualified human and material resources required for the assembly, transport and installation of the facade cladding. Summary of the invention

[0013] The present invention aims to improve the current situation described above.

[0014] The present invention aims more particularly to remedy the above drawbacks- above by offering a blade, a cladding system and a kit for facade cladding allowing simplified assembly. Such simplification makes this assembly accessible to an individual, and reduces the carbon impact of the construction sector.

[0015] In particular, the present invention is dedicated to the insulation of a facade, that is to say to providing a facade cladding comprising insulating means, in particular in the context of a thermal rehabilitation of a building. The present invention can also be used so as to produce a simple cladding, without any particular impact on the insulation. The present invention can for example be used, with respect to a building having a ground floor and an attic, the attic being already insulated, to provide a first insulated cladding at the ground floor level and a second non-insulated cladding at the attic level, completing the structure and appearance of the first cladding.

[0016] To this end, the subject of the present invention relates in a first aspect to a frame blade for cladding and insulating the facade of a building, the blade having substantially the shape of a rectangular parallelepiped extending longitudinally finally along a first axis defining two longitudinal ends separated by a set of lateral edges of the blade.

[0017] Advantageously, the blade has a set of notches arranged along one of the lateral edges, the notches being configured to allow the nesting, in one of the notches of the blade, of one of the notches of another similar blade placed perpendicular to the blade, the lateral edges provided with notches of the two blades being placed opposite one another, the nesting allowing the immobilization of the two blades in the plane formed by them and being done along a trajectory perpendicular to the plane, the blade being configured both to form a crosspiece and an upright of the frame.

[0018] The blade can be made of any material, and correspond for example to a blade of wood, metal, or composite material.

[0019] Preferably, the blade has a relatively planar shape along the first axis. Those skilled in the art will identify, for example, that the length and width of the blade define the faces (also called "flat") of the blade, the length and thickness define the (lateral) edges of the blade, and the width and thickness define the tips of the blade, i.e., the longitudinal ends. The lateral edges encompass both the faces and the edges of the blade.

[0020] The notches are also preferably arranged along the lateral edges of the blade, that is to say that the notches pass entirely through the thickness of the blade, and partially through its width.

[0021] It is understood here that the nesting corresponds to the assembly of two blades, one perpendicular to the other, according to their respective notches. The blades are thus maintained at this angle, so that one of the blades forms an upright and the other blade forms a crosspiece of a frame for the cladding and insulation of a building. When the two blades are assembled, the other blade thus extends along a second axis perpendicular to the first axis, the plane being formed by the first axis and the second axis.

[0022] It is also understood that the assembly of the frame simply corresponds to the nesting of a set of blades into each other, via their notches, so as to form the set of uprights and crosspieces. Such an assembly is extremely simple and does not require any sophisticated mechanical tools or particular skills.

[0023] The design of the notches for assembling the blades thus helps to enable the same blade to form both an upright and a crosspiece. It is also understood that the entire design of the blade meets the constraints necessary for an upright and a crosspiece, so that the blade can fulfill each role.

[0024] In particular, the frame blade is here dedicated to the cladding and insulation of a building, that is to say to the production of a cladding specific to the insulation. This design thus results in a specific dimensioning and set of constraints, distinguishing the frame blades according to the present invention from the uprights and crosspieces commonly used for facade claddings having structural functions. As stated previously, such cladding may also, in certain cases, be devoid of insulation. Naturally, the non-provision of insulation does not result in additional structural stress on the frame blades.

[0025] The Applicant further submits that this design makes it possible to limit the uprights and crosspieces to their functions of carrying insulation and a cladding material. This design is therefore particularly suitable in the manufacture of facade cladding requiring, at most, only these two elements, particularly during the thermal renovation of a building.

[0026] Thanks to the present invention, the assembly of the frame is extremely simplified and can be carried out In Situ as well as Off-Site, directly on or near the facade. As a result, the frame does not need to be transported assembled over long distances, the blades being able to be transported in a more compact manner, that is to say in greater numbers and / or in lighter vehicles. The tooling, personnel and transport constraints associated with the cladding of a facade are therefore greatly reduced.

[0027] In an advantageous embodiment of the present invention, the blade is further provided with a first set of fixing holes configured for receiving means for fixing the cladding and the facade insulation.

[0028] Such holes correspond for example to through or non-through holes. The fixing means correspond for example to pins, fishplates, or any other fixing means known to those skilled in the art and used in the field.

[0029] Preferably, the holes are arranged along the flats of the blade, as defined above, so that, when a plurality of blades are assembled together, the holes are arranged on the lateral faces, left-right or top-bottom, of the blades forming uprights and crosspieces. Optionally, the holes are also arranged along the ends of the blade. This design also allows the arrangement of fixing means at the ends of the frame, as well as the end-to-end assembly of two blades, for example via dowels.

[0030] It is also understood that, when the blades are made of a relatively soft material, for example wood, the fixing means can be directly screwed onto the blade, without requiring prior holes. The placement of holes can however still be useful in such a case, as an aid in positioning the fixing means.

[0031] In an embodiment that can be combined with the previous embodiment, the blade is provided with a second set of fixing holes configured to receive means for adjusting the depth of the notches.

[0032] The first set and the second set of fixing holes are for example merged into a single set of fixing holes, the different means being able to be freely fixed on various fixing holes of the blade, according to their design and the different advantages of the position of the fixing holes. Alternatively, the first set and the second set of fixing holes correspond to holes arranged in very distinct positions of the blade.

[0033] Such adjustment means correspond for example to any means forming a stop for the interlocking of the notches of two blades, for example a pin assembled with the fixing holes and extending through the notches.

[0034] It is understood that such means for adjusting the depth of the notches make it possible not to push the blades completely into each other. Each blade has, for example, a lateral edge opposite the lateral edge provided with the notches, the adjustment means being arranged so that, when another similar blade is nested in the blade, the lateral edge provided with the notches on one of the blades is offset relative to the opposite lateral edge on the other similar blade and vice versa.

[0035] In other words, when the slats are nested to form a set of uprights and crosspieces, the front (or rear) flank of the uprights has a spacing relative to the front (or rear) flank of the crosspieces, the concept of front (or rear) flank being taken into account in the arrangement of a facade cladding, the front extending from the facade, and the rear approaching the facade. The front flanks are therefore not arranged in the same plane. In other words, the slats nest together along a trajectory perpendicular to the plane formed by the slats, that is to say along a third axis perpendicular to the first axis and the second axis. When they are nested, the slats have, relative to each other, an offset along this third axis, in particular between a lateral edge of one slat and the opposite lateral edge of the other slat. This design allows for ventilation space to be maintained via the recessed front flanks.This design also allows the installation, in the frame, of insulation of a thickness additional to that of the slats. The same slat can therefore be adapted to form a frame of variable thickness, according to the needs and constraints of the facade to be dressed and / or insulated.

[0036] Preferably, the fixing holes, in particular the fixing holes of the second set of fixing holes, are at least partially arranged between the notches.

[0037] This design thus makes it easier to receive means for adjusting the depth of the notches, for example by assembling a stop with two fixing holes arranged on either side of a notch.

[0038] In a particular embodiment, the notches are uniformly distributed along said first axis.

[0039] This design also makes it possible to simplify the assembly between the slats, without requiring any specific orientation or order in the assembly. A high number of uniformly distributed notches makes it possible both to precisely position the uprights and crosspieces with respect to the facade, by selecting the notches arranged at the correct dimensions, and to facilitate the assembly work, the notches serving as a guide.

[0040] Preferably, the fixing holes are also uniformly distributed, so as to also allow relatively free placement of the fixing means, and by extension the facade cladding and insulation parts.

[0041] In an additional embodiment, the blade has a thickness of between 1 and 2 centimeters, the notches being arranged on the edge of the blade.

[0042] It is understood here that the thickness of the blade corresponds to its smallest dimension, the notches being arranged according to the thickness of the blade, on the lateral edges.

[0043] The Applicant submits that this thickness makes it possible to optimize the mechanical strength of the frame formed by the assembly of the blades, in particular for a facade with a height of between 3 and 5 meters, while minimizing their weight and volume for reduced bulk during their transport and assembly. Blades of reduced weight also make it possible to simplify the lifting of an assembled frame, or even of a cladding or a portion of a facade cladding comprising the blades.

[0044] In yet another embodiment, the blade has a maximum length of 5 meters.

[0045] Preferably, the blade has a length of between 3 and 5 meters.

[0046] It is understood here that a limited length allows simplified transport of the blades, these being able to be transported in a light vehicle or a trailer without requiring a dedicated heavy goods vehicle. A length of approximately 3 meters remains an appropriate dimension for cladding a facade of a dwelling, an upright being able to be used for cladding an entire floor. Similarly, a length of approximately 5 meters is suitable for cladding facades of buildings in the tertiary sector, in particular offices.

[0047] A plurality of adjacent blades, for example crosspieces, can be assembled together via fixing means, for example fishplates and / or dowels assembled on the fixing holes as described above.

[0048] According to a second aspect, the present invention relates to a kit for cladding and insulating a facade of a building, the kit comprising a set of blades according to the first aspect of the present invention, the blades being configured to form a set of crosspieces and uprights of a framework of the cladding and facade insulation.

[0049] It is understood here that the kit comprises a plurality of blades capable of fitting into one another so as to form the crosspieces and the uprights.

[0050] The assembly of the blades thus forms a light framework which can serve as a support for insulation and facade cladding, in particular for insulation means and cladding.

[0051] Obviously, the kit may include a plurality of additional elements necessary for the assembly of the cladding and the facade insulation. It is also understood that minimizing the number of separate elements simplifies assembly, manufacturing and transport. Such additional elements correspond, for example, to constituent elements of the cladding and the facade insulation or to tools used for the installation of the facade cladding.

[0052] In a particular embodiment, the kit further comprises a set of means for adjusting the depth of the notches of the blades.

[0053] It is understood that such means correspond to the depth adjustment means described with regard to the first aspect of the present invention. Preferably, the blades are configured to receive such depth adjustment means according to the fixing holes as described above. The fixing of the adjustment means may vary depending on their specific design, as well as the nature of the blades. It is therefore, for example, also possible for the adjustment means to be fixed directly to wooden blades, without a prior hole, or for the adjustment means to comprise their own fixing means, for example clamping means on the blades.

[0054] In one embodiment, the kit further comprises a set of rails configured to be fixed to the facade, the rails being provided with brackets configured to receive the uprights.

[0055] It is understood here that the reception of the uprights by the rail brackets allows the facade cladding to be fixed to the building. The rail brackets correspond to parts extending substantially perpendicularly from the rails and forming a support point. The rails are for example configured to extend across the width of the facade, the brackets extending substantially perpendicularly from the facade.

[0056] The rails are for example made of aluminum, or any other light and solid material allowing the reception of the uprights, and by extension of the facade cladding.

[0057] Preferably, the kit further comprises a first compression insulator sized to be fixed to the facade between the rails.

[0058] The compression insulation allows, in addition to its thermal insulation functions, to compensate for imperfections and protrusions of the facade, for example moldings, so as to present a substantially flat profile.

[0059] The compression insulation is preferably sized so as to be installed in the thickness of the rails, i.e. so that when the compression insulation and rails are fixed to the façade, the compression insulation does not extend beyond the rails. This design ensures that the compression insulation does not collide with the rest of the cladding, including the studs and transoms.

[0060] The compression insulation is for example dimensioned with respect to a precise height and / or width, i.e. specifically with respect to a type of facade, for example also taking into account openings with respect to windows or doors. According to another variant, the compression insulation has given maximum dimensions and is configured to be cut according to the desired dimensions, so as to adapt it to the dimensions of the facade.

[0061] The kit may additionally comprise means for fixing the compression insulation, for example fixing rosettes configured to be regularly arranged on the surface of the compression insulation.

[0062] In a particular embodiment, the kit further comprises: - a set of second insulators configured to be placed between the uprights and the crosspieces at least partially over the thickness of the frame; and - a set of fixing claws configured to be attached to the uprights and to hold the second insulators in position.

[0063] It is understood here that, when the uprights and crosspieces, that is to say the slats, are assembled together, the uprights being perpendicular to the crosspieces, these form a set of spaces or "boxes" of substantially rectangular shape. The second insulators are then placed inside each space.

[0064] The dimensions of the second insulators may be predetermined, for example according to a predefined center distance between each upright and each crosspiece. According to another variant, the second insulators are packaged in one or more blocks of given dimensions, and capable of being cut according to the dimensions of the spaces between the slats, in particular when the center distance varies between the different uprights and crosspieces of the frame. Second insulators of approximately 15 cm thickness are preferably provided.

[0065] The thickness of the frame corresponds for example at least to the width of the slats as defined above, optionally increased by the distance by which the lateral edges of the slats are offset from each other. The thickness of the second insulators is thus for example determined so that the second insulators do not extend beyond the thickness of the frame.

[0066] The fixing claws correspond for example to parts in the shape of a bracket, configured to be fixed on the lateral edges of the uprights or crosspieces, in particular via the fixing holes, and to extend, at the level of the front face of the uprights or crosspieces, towards the inside of each space.

[0067] Optionally, additional means for fixing the second insulators are provided, for example strings configured to be attached to the notches or fixing holes, and passing through the spaces so as to block the movement of the second insulators.

[0068] The second insulators may be made of flexible, semi-rigid or rigid materials without specific restriction, provided that the associated fixing means are suitable for holding them in position.

[0069] In a specific embodiment, the kit further comprises: - a set of panels configured to form a cladding for the facade cladding; and - a set of panel fixing brackets.

[0070] The cladding here corresponds to the facade covering of the cladding, in particular so as to protect the facade from the rain as well as to define the aesthetic appearance of the facade. The panels can thus be made of a plurality of materials, for example of wood treated for its waterproofing or of a composite material.

[0071] The panels have, for example, a line creating a drip breaker in the lower part, when they are mounted as cladding. The panels are for example configured to be arranged horizontally along the facade, the line creating a drip breaker being arranged along the flat of the panels, close to one or more side edges.

[0072] The fixing lugs correspond to parts configured to receive and hold the panels so as to create the cladding. The fixing lugs are fixed to the frame, preferably attached to the uprights, for example via pins, so that the panels extend parallel to the crosspieces. Their dimensioning allows the removal of a blade without having to intervene on the entire row. In particular, panels arranged horizontally can be held in position by the fixing lugs simply by gravity. The assembly is then greatly simplified, the panels only having to be placed or slid onto the fixing lugs.

[0073] Advantageously, the fixing lugs and the panels are configured so that, when the panels are assembled with the fixing lugs to form the cladding, the panels are arranged adjacent to each other, each end of a panel being covered by another end of an adjacent panel.

[0074] It is understood here that the adjacent panels partially overlap each other. Obviously, a panel arranged at the end of the cladding may not overlap or be covered by another panel. Preferably, panels are provided extending horizontally, parallel to the crosspieces, and arranged so that the lower end of an upper panel overlaps the upper end of a lower panel. This design thus makes it possible to form, in other words, a mechanical overlap of the panels, preferably a mechanical overlap over the height. Such a mechanical overlap makes it possible to prevent any water infiltration, without resorting to a rain screen. Such a rain screen, as known to those skilled in the art, is in fact a complex part to install. On the contrary, the installation of panels overlapping each other is simpler to implement and does not require any particular skill.

[0075] Preferably, the fixing lugs are configured to be attached to the uprights, each fixing lug being provided with two slots for receiving the panels arranged along two opposite lateral edges of the fixing lugs, each fixing lug extending in a substantially longitudinal direction and each slot extending obliquely with respect to the longitudinal direction.

[0076] The receiving slots are then arranged substantially obliquely to the vertical, so as to receive an upper end of a lower panel and a lower end of an upper panel. The panels are then held simply by gravity in the fixing lugs, and mechanically overlap in height.

[0077] The fixing lugs are for example dimensioned so that, when the fixing lugs are attached to the uprights, the receiving slots are offset from the uprights, so as to allow ventilation between the uprights and the panels. In other words, the fixing lugs maintain a space between the uprights and the panels, the space allowing air circulation.

[0078] It is further understood that, according to other variants, the frame receives traditional cladding as known to those skilled in the art, in particular cladding provided with a rain screen. The kit may thus comprise such traditional cladding. It is thus provided, in such an example, that the frame receives cubic pieces, in particular made of wood, in some of the corners formed by the uprights and the crosspieces, so as to receive traditional cladding comprising a rain screen in the bare edges, vertical lathing fixed to the cubic pieces, and cladding arranged directly on the lathing or on counter-slats.

[0079] In yet another embodiment, the kit further comprises a set of finishing sheets for sealing the facade cladding, the sheets having a plurality of grooves extending transversely to a length of the sheets, the grooves being configured to allow the folding and / or cutting of the sheets along one of the grooves.

[0080] It is understood here that the sheets make it possible to complete the cladding and ensure its watertightness, in particular on the ends of the structure. The sheets thus make it possible to produce a cover in the upper portion, an anti-rodent grid in the lower portion lower, corner junctions or window splays, etc. The sheets also have, for example, a return forming a drip breaker on the outside, so as to complete the waterproofing of the facade.

[0081] The grooves thus make it possible to adapt the length and / or shape of the sheets without requiring specific tools or skills, so as to adapt the shape of the finishes to the shape of the building. The grooves are, for example, arranged regularly along the sheet, for example every 5 centimeters.

[0082] The sheets are for example fixed to the crosspieces via fishplates or any other fixing means known to those skilled in the art. For example, angles are provided configured to be arranged on an internal portion (i.e. opposite the facade) of the sheets so as to allow the sheets to be fixed to the rest of the structure.

[0083] In another embodiment which can be combined with the previous embodiments, the kit is packaged in the form of a block with a maximum length of 5 meters.

[0084] As stated above, a maximum length of 5 meters is suitable for cladding a facade, an upright being able to be used for cladding an entire floor, and adjacent crosspieces being able to be assembled in particular via fishplates and / or dowels. More precisely, a length of approximately 3 meters is suitable for cladding a facade of a dwelling. Similarly, a length of approximately 5 meters is suitable for cladding facades of buildings in the tertiary sector. The block preferably has a length of between 3 and 5 meters.

[0085] Packaging the kit in the form of a pack of reduced dimensions makes it much easier to transport, by ensuring that a kit can be transported by a light vehicle or trailer, or that a larger quantity of kits can be transported by a truck. The packaging of the kit can be further optimized by providing dimensions that are multiples of each other, so as to facilitate storage and transport. The Applicant submits in particular that the kit can be packaged in such a way that a truck can transport 20 times more kits than assembled frames, or in other words that the kit is packaged in a volume at least 20 times smaller than that of an assembled frame.

[0086] According to a third aspect, the present invention relates to a set of panels configured to form a facade cladding, and a set of fixing lugs for said panels, the fixing lugs and the panels being configured so that, when the panels are assembled with the fixing lugs to form the cladding, the panels are arranged adjacent to each other, each end of a panel being covered by another end of an adjacent panel.

[0087] It is understood here that the third aspect of the present invention relates to a set of panels and fixing brackets as described with respect to the second aspect of the present invention. The same details of embodiment, characteristics and advantages described above with respect to the set of panels and fixing brackets are also applicable with respect to the third aspect of the present invention.

[0088] Such a set of panels thus makes it possible to provide a simple solution for producing facade cladding, which can be assembled to a frame formed from the blades according to the first aspect of the present invention, or to any other frame known to those skilled in the art. In particular, this set of panels can also be assembled to a heavier frame in projects presenting additional structural constraints.

[0089] Such a set of panels and fixing brackets may also be packaged in the form of a kit, in particular a kit comprising other additional elements necessary for the assembly of the facade cladding. This set of panels and fixing brackets may also be integrated into a variety of other kits for the production of cladding, for example kits for the assembly of a complete cladding of a facade, or even a kit for the assembly of a facade itself.

[0090] According to a fourth aspect, the present invention relates to a method for directly installing a facade cladding on a wall using a kit according to the second aspect of the present invention, in which a platform forming a scaffold is temporarily assembled with some of the notches of the uprights fixed to the facade, the facade cladding being installed partially from the platform and then completed once the platform has been removed from the uprights.

[0091] This first type of assembly is intended for individuals, with a particularly simplified assembly requiring no specialized tools or skills, for buildings whose size is limited to a ground floor not requiring scaffolding. As stated above, this method is particularly advantageous for the installation of a cladding provided with insulation, but can also be used for the installation of a cladding without insulation.

[0092] It is understood here that the method of installation on the wall comprises a plurality of steps corresponding to the installation of the different constituent elements of the kit, and optionally of additional elements not included in the kit and used for the cladding and / or insulation of the facade. The kit corresponds for example to an assembly comprising at least the blades so as to produce the framework, all or part of the other elements being supplied separately from the kit.

[0093] In particular, this direct wall installation method corresponds to a method in which the various elements of the cladding and / or facade insulation are assembled directly on the wall, without requiring prior assembly.

[0094] The installation of a platform forming scaffolding on the uprights makes it possible to provide a easy access to the upper portions of the facade. It is understood that the uprights are arranged to receive the crosspieces according to their notches, that is to say that the notches of the uprights are arranged to present horizontal alignments. The platform can therefore be assembled, like a crosspiece, according to one of these horizontal alignments.

[0095] The platform is for example additionally equipped with metal rods forming corbels in order to stiffen it. A platform installed at most one meter high allows access to approximately 3 meters high, corresponding to the average height of the eaves of a single-family house comprising a ground floor and attic. The upper portion of the cladding can therefore be installed from the platform, without requiring dedicated scaffolding or specialized equipment. The lower portion of the cladding can then be installed after the platform has been removed.The upper portion of the cladding corresponds, for example, to the part of the cladding located above the platform, or to any part of the cladding that is easily accessible when the platform is assembled on the uprights, for example also including lateral portions of the cladding or by removing parts of the cladding that are too close to the platform and difficult to access from the platform. The lower portion of the cladding thus corresponds to the remaining portion of the cladding, once the upper portion has been installed.

[0096] This design thus allows the installation of the facade cladding of a building, by directly assembling all the parts on the facade, up to a height of 3 meters, and without requiring specialized tools or qualified personnel. The installation of the cladding is therefore greatly simplified, and can be carried out by an individual.

[0097] According to another variant, it is possible to envisage the direct installation of the cladding at higher heights, in particular by providing for the addition of stairs and / or guardrails on one or more levels.

[0098] According to a fifth aspect, the present invention relates to a method for indirectly installing a facade cladding on a wall using a kit according to the third aspect of the present invention, the method comprising a projection of the facade onto an offset platform, the facade cladding being assembled on the offset platform according to the projection, then installed on the facade by lifting.

[0099] By remote platform is meant here any support on which the facade cladding can be assembled, separate from the facade for which the cladding is dedicated. Such a remote platform may for example correspond to a platform of a flatbed truck, close to the facade, or even in a separate workshop, for example in the absence of space close to the facade.

[0100] It is understood here that this design corresponds to an assembly of the facade cladding, in particular of the frame from the blades according to the first aspect of the invention, separately from the facade, before its installation and fixing on the facade.

[0101] This design is particularly suitable for the installation of cladding on facades of large dimensions, for which direct assembly on the facade would be complex and / or dangerous. Assembly on a remote platform always makes it possible to avoid transport-related constraints, by assembling the cladding as close as possible to the facade before its installation. If such an assembly remains more restrictive than direct installation on the wall, it still requires simpler tools than previously due to the design of the slats. This second type of assembly is intended for professionals, with comparatively simplified assembly, for any building size, in particular for a building comprising several levels and requiring a lifting means and the installation of scaffolding.As stated above, this process is particularly advantageous for installing a cladding with insulation, but can also be used for installing a cladding without insulation.

[0102] The projection of the facade is for example carried out at least partially via rulers equipped with laser, allowing a precise transfer of the dimensions of the facade, in particular the width and position of each subdivision sought, for example the total width of the facade, the width of the windows and doors. The cladding is therefore assembled precisely directly before its installation, respecting the dimensions of the facade.

[0103] Thus, through the various functional and structural technical characteristics above, the Applicant proposes a blade for facade cladding, as well as a kit for facade cladding and associated installation methods, allowing simple assembly of the framework of the facade cladding, from a minimum of basic elements, requiring little material, optimizing transport, and suitable for In Situ or Off Site renovation projects of buildings, by individuals or professionals, in particular in order to improve their insulation and their energy efficiency.

[0141] A frame blade for a facade cladding and insulation, a kit for facade cladding and insulation, a method for direct installation on a wall and a method for indirect installation on a wall of a facade cladding will now be described in what follows with joint reference to Figures 1 to 18. The same elements are identified with the same reference signs throughout the description which follows.

[0142] [Fig.l] describes a frame 2' for a facade cladding known from the prior art. The frame 2' is composed of a set of uprights 21' and crosspieces 22' assembled together, each upright 21' and crosspiece 22' corresponding to a bar or blade made of wood, metal, or even composite material. The frame 2' thus forms a robust structure to support the cladding elements of the facade.

[0143] As indicated in the preamble to the description, the frame 2' of the prior art corresponds to a relatively heavy and bulky structure, which can be assembled in a dedicated warehouse before being transported to the site of its installation, i.e. to the facade for which the frame 2' is dedicated. By nature, the frame 2' is mainly hollow, or empty, and its transport is particularly restrictive with respect to the actual quantity of material transported. In addition, such a frame 2' is oversized with respect to certain facade cladding operations, in particular thermal renovation operations, which are mainly aimed at providing a new waterproof and insulating cladding, without additional function. Even when the 2' frame is assembled directly in situ, the installation of the cladding, in particular the assembly of the 2' frame, is a complex operation requiring dedicated equipment and qualified personnel.

[0144] One of the objectives of the present invention is to propose a new type of element for manufacturing a frame allowing optimization of material, simplified assembly accessible by individuals and greatly reduced transport.

[0145] This is made possible in the examples described below, which consider the installation of cladding and insulation on a plurality of facades using the present invention. It will be understood that these examples are not limiting and in particular that the invention can be adapted to numerous facade geometries, without direct limitation.

[0146] According to the example of figures 2, 3 and 6, a dedicated blade 1 is provided for the production of a frame 2. The blade 1 has substantially the shape of a rectangular parallelepiped and extends longitudinally along a first axis Z. The blade 1 thus defines two longitudinal ends (or “tips”) 11 and lateral edges 12, 13. In this example, the blade 1 also defines edges 12 and faces (or “flats”) 13. The blade 1 thus has a length along the first axis Z, a thickness along a second axis Y and a width along a third axis X.

[0147] As illustrated in Figures 2 and 3, the blade 1 also has a set of notches 14 arranged along a lateral edge 12, 13, here along an edge 12. The notches 14 therefore extend along the entire thickness of the blade 1, and along a portion of the length and width of the blade 1. Each notch 14 is configured to allow the nesting, in the blade 1, of a notch 14' of another similar blade 1'.

[0148] [Fig. 3] thus illustrates two blades 1, 1' nested according to one of their notches 14, 14'. This nesting thus corresponds to an assembly of the two blades 1, 1', in which the lateral edges 12, 13 provided with notches 14, 14' are placed opposite each other, and the blades 1, 1' are oriented perpendicularly to each other. In this example, the blade 1 extends along the first axis Z while the other blade 1' extends along the second axis Y. The nesting thus corresponds to a relative translation of the blades 1, 1' along the third axis X, and locks the movement of the blades 1, 1' along the first axis Z and the second axis Y.

[0149] Consequently, the design of the blade 1 allows it to be assembled with at least one other blade 1', so that the two blades 1, 1' extend perpendicular to each other. The two similar blades 1, 1' being configured for the production of a frame 2, they can then alternately play the role of an upright 21 or a crosspiece 22, as illustrated in [Fig.6]. For example, it is considered that the blade 1 forms an upright 21 and that the other blade 1' forms a crosspiece 22 of the frame 2. The two 1,1' blades being structurally identical, they are interchangeable in these roles. In addition, the interlocking of the 1,1' blades being done by simple manipulation and translation of the 1,1' blades, it does not require any specialized tool.

[0150] As illustrated in [Fig.2], the blade 1 has a plurality of notches 14, so as to be able to receive a plurality of other blades 1' in different positions along the first axis Z. It is advantageously provided that the notches 14 are uniformly distributed along the first axis Z, without variation with respect to the orientation of the blade 1 or the distance from the ends 11. [Fig.6] thus illustrates a frame 2 composed of a plurality of uprights 21 and crosspieces 22, each upright 21 being assembled with several crosspieces 22 and vice versa.

[0151] As stated above, the blade 1 is sized to form both an upright 21 and a crosspiece 22, that is to say it is sized to form part of the frame 2, in particular a frame 2 for supporting a facade cladding, comprising insulation means, sealing means and finishes. It is thus expected that the blade 1 has a thickness of between 1 and 2 centimeters, corresponding to its smallest dimension. It is also expected that the blade 1 has a length of between 3 and 5 meters. Such a length allows the production of an upright 21 of a size adapted to a floor of a building, or even to the total height of a single-story building. In addition, the transport of the blades 1 is simplified by limiting their maximum dimension.

[0152] Additionally, a set of fixing holes 15 ([Fig.2]) are provided on the blade 1. The fixing holes 15 are for example provided on the flats 13 of the blade 1. Alternatively or in addition, the fixing holes 15 can also be provided on the ends 11 of the blade 1.

[0153] The fixing holes 15 thus make it possible, separately from the notches 14, to receive a plurality of fixing means. The fixing holes 15 allow in particular the assembly of a facade cladding on the frame 2. The fixing holes 15 also allow the assembly of adjacent blades 1, for example by arranging dowels along the ends 11 or by assembling fishplates on the flats 13. This design makes it possible to ensure that a blade 1 with a maximum length of 5 meters can be used for cladding a facade of larger dimensions.

[0154] In this example, the blades 1, 1' are nested together so that their edges (or lateral edges) 12, 12' are located in the same plane (Y, Z). The notches 14, 14' thus extend substantially along half the width of the blades 1, 1' so as to achieve this alignment. According to a variant, it is provided that the fixing holes 15 are configured to receive means for adjusting the depth of the notches 14, 14', in particular means forming a stop before the two blades 1,1' are fully nested within each other. This design results in the edge 12 of the blade 1 being offset relative to the edge 12' of the other blade 1'. When the edges 12, 12' of the blades 1, 1' are offset, the frame 2 has a more irregular profile to ensure ventilation between the uprights 21 and the crosspieces 22. In addition, the total thickness of the resulting frame 2 is greater than the thickness of the blades 1,1', allowing more insulation to be accommodated.

[0155] It is thus understood that the blade 1 according to the present invention is intended to be used in conjunction with a plurality of other similar blades 1', so as to form a framework 2. Advantageously, a kit is provided comprising a plurality of blades 1, 1'. Such a kit thus corresponds to a predetermined number of blades 1, 1' necessary for the cladding and optionally the insulation of a given surface. Due to the simplicity of assembly of the blades 1, 1', the kit can be directly transported to the installation site, for example by truck, before assembly. As illustrated in [Fig.4], this kit can thus be packaged in the form of a block 29 of compact dimensions, in particular of a length of between 3 and 5 meters, just like the blades 1, 1'. A block has for example a format of 3 mx 0.3 mx 0.3m, and can be easily stacked in a transport vehicle.A single truck can thus transport a large quantity of kits for the cladding of a large number of buildings, or a light vehicle can transport one or more kits for the cladding of a specific building, without requiring a truck. The Applicant thus estimates that a single truck sized for the transport of 8 2' frames of the prior art can then transport up to 160 kits according to the present invention, corresponding to a number 20 times higher of 2 frames, and by extension of number of facades and associated buildings.

[0156] Once transported, the kit can thus be used for cladding and insulating a facade 4 of a building, for example one of the methods described in figures 5 to 9, 10 to 13, or 14 to 16.

[0157] Figures 5 to 9 thus describe the different steps of a method for installing a cladding 3 on a facade 4, from a set of blades 1, 1' according to the present invention. The blades 1, 1', as well as other elements used during this method, may be part of the kit as described above.

[0158] In a first step illustrated by [Fig.5], a set of rails 23 is fixed to the facade 4. The rails 23 are for example fixed along the upper and lower ends of the facade 4, or else along a distance corresponding substantially to the length of a blade 1. The rails 23 are also provided with brackets 231 for receiving the uprights 21 of the frame 2. It can be seen here that the rails 23 extend substantially horizontally. According to another variant, rails 23 are provided extending substantially vertically, the brackets 231 then being configured for receiving the sleepers 22.

[0159] Additionally, a first compression insulator 24 is fixed to the facade 4, between the rails 23. The first insulator 24 is for example fixed via a plurality of fixing rosettes 241. Such fixing rosettes 241 pass through the first insulator 24 to attach to the facade 4, and has a flat surface holding the first insulator 24 against the facade 4. As illustrated in [Fig. 5], the first insulator 24 is also adapted to the particularities of the facade 4. The first insulator 24 is for example cut to leave openings corresponding to the windows and / or doors of the facade 4, or more generally to any portion of the facade 4 not intended to be covered by the cladding 3.The first insulator 24 is also advantageously sized so as to be laid in the thickness of the rails 23, that is to say so as not to extend from the facade 4 beyond the rails 23, in particular so as not to block the laying of the frame 2 or any other element on the consoles 231.

[0160] In a second step illustrated by [Fig.6], the uprights 21 and the crosspieces 22 are assembled on the facade 4. As stated above, in this example, the uprights 21 are assembled to the rails 23, for example in a regular manner according to the length of the rails 23. Like the first insulator 24, the blades 1, both for the uprights 21 and the crosspieces 22, are adjusted to the dimensions of the facade 4. The length of the blades 1 is for example adjusted by simple cutting, in particular in the case of wooden blades 1, using a saw. The notches 14 also assist in cutting the blades 1, by providing a less wide portion to be cut as well as a reference position along the length of the blade 1.Furthermore, the maintenance of the blades 1 can also be improved by also providing rails at the openings of the facade 4, for example at the supports and lintels of the facade 4, so as to provide support in the upper and lower portions of each upright 21, even when the latter is cut.

[0161] In a third step illustrated by [Fig.7], a set of second insulators 25 is placed between the uprights 21 and the crosspieces 22. The assembly of the uprights 21 and the crosspieces 22 in fact forms a set of empty spaces ([Fig.6]), in which the second insulators 25 can be arranged and held in position. Thus, just as the first insulator 24 is placed in the thickness of the rails 23, the second insulators 25 are placed in the thickness of the frame 2. The second insulators 25 have, for example, a thickness of approximately 15 cm. Like the first insulator 24, the second insulators 25 are adapted to the dimensions of the empty spaces, for example so as to respect a defined center distance between each upright 21 and crosspiece 22, or even adapted and cut with respect to the specific shape of the frame 2. The second insulators 25 can be made of a flexible, semi-rigid or rigid material, provided that these can be held in position.

[0162] For this purpose, a set of fixing claws 251 is provided, illustrated in Figures 7 and 9, which are attached to the uprights 21 and hold the second insulators 25 in position. In this example, the fixing claws 251 have a right-angle shape, comprising a first portion attached to the flats of the uprights 21, and a second portion extending orthogonally to the first portion, and extending towards the inside of the empty spaces, that is to say towards the second insulators 25. The fixing claws 251 are for example assembled via the fixing holes 15. The fixing claws 251 then form a stop for the second insulators 25. Obviously, other variants can also be provided, in particular fixing claws 251 assembled to the crosspieces 22 or even fixing claws 251 assembled both to the uprights 21 (and / or to the crosspieces 22) and to the second insulators 25.In this same example, strings 252 are also provided, configured to hold the second insulators 25 in position. The strings 252 extend in front of the empty spaces, for example diagonally or in any other orientation, so as to form an obstacle with respect to the second insulators 25. The strings 252 are also assembled to the uprights 21 and / or to the crosspieces 22, for example via the notches 14 and / or the fixing holes 15.

[0163] In a fourth step illustrated by Figures 8 and 9, a set of panels 26 is assembled on the frame 2. The panels 26 form a cladding of the cladding 3 of the facade 4, that is to say they form the external covering of the cladding 3. Such panels 26 can be made of a plurality of materials, for example treated wood or composite material. In this example, the panels are arranged longitudinally along the crosspieces 22 of the frame 2, that is to say so as to extend horizontally. The panels 26 are assembled via fixing lugs 27, which are attached to the uprights 21, in particular via the fixing holes 15, for example using pins.

[0164] [Fig. 9] illustrates in more detail the assembly of the fixing lugs 27 and the panels 26. The fixing lugs 27 thus have a first portion configured to be hooked to the uprights 21, from which extends a second portion for receiving the panels 26. Each fixing lug 27 is then provided with a first receiving slot 271 for a lower end of an upper panel 26, and a second receiving slot 272 for an upper end of a lower panel 26, the two receiving slots 271, 272 being arranged along opposite lateral edges of the fixing lug 27. Each panel 26 is thus held by the upper and lower fixing lugs 27. In particular, as illustrated in [Fig. 8], the fixing lugs 27 are assembled to a plurality of uprights 21, along the facade 4, thus forming a plurality of points of support panels 26. The panels 26 are for example assembled with the fixing lugs 27 by sliding them in their longitudinal direction. In addition, the space between the first portion and the second portion of the fixing lugs 27 provides ventilation between the panels 26 and the rest of the cladding 3.

[0165] Advantageously, the second receiving slot 272 is set back from the first receiving slot 271, and the receiving slots 271, 272 extend substantially obliquely relative to the longitudinal direction of the receiving tab 27, so that the receiving slots 271, 272 of two adjacent receiving tabs 27 on the same upright 21 are opposite each other. Thus, when the panels 26 are assembled with the fixing tabs 27, each panel extends substantially obliquely relative to the vertical, the upper end of the panels 26 is set back from the lower end of the panels 26. In other words, the upper end of the panels 26 is closer to the frame 2, and the lower end of the panels 26 is further from the frame 2.This design results in a mechanical covering of the panels 26 over the height of the cladding 3, which improves the sealing of the cladding, by naturally redirecting the drops towards the outside of the cladding 3.

[0166] In a fifth step, also illustrated by figures 8 and 9, a set of finishing sheets 28 are assembled on the frame 2. These sheets 28 make it possible to ensure the sealing of the cladding 3, in particular according to the thickness of the frame 2. The sheets 28 are thus arranged according to the ends of the cladding 3 not covered by the panels 26. In this example, provision is thus made to arrange a coping according to the upper end of the cladding 3, an anti-rodent grid according to the lower end of the cladding 3, as well as a profile following the angles of the opening in the facade 4 and profiles of supports, lintels and panels at the right of the windows. This set of sheets 28 can also be supplemented by sheets 28 at the lateral ends of the cladding 3. The assembly of the sheets 28 on the frame 2 is for example carried out via fishplates assembled to the uprights 21 and / or to the crosspieces 22.

[0167] The method described above can thus be adapted to a plurality of installation scenarios, depending on the material conditions, the constraints of the facade 4, as well as the personnel available for the installation of the cladding 3.

[0168] The example of figures 10 to 14 thus describes a method of directly installing a cladding 3 of a facade 4 on a wall, using the kit described above, and repeating at least partially the steps of the generic method of figures 5 to 9. More precisely, figures 10 to 13 describe in detail different phases of the direct installation method, [Fig. 14] illustrating the complete sequence of the steps of the method.

[0169] In particular, such a direct laying method can be carried out without requiring specialized equipment, lifting means or scaffolding, and is suitable for the rea lisation of a cladding 3 of a facade 4 of approximately 3 meters in height, that is to say a template limited to a ground floor. This process can thus at least partially be carried out by individuals, without specific skills.

[0170] As illustrated in [Fig. 10], rails 23 are laid along the facade 4, and uprights 21 are assembled on the rails 23. Without scaffolding or lifting means, the rails 23 can be laid up to a maximum height of 2 meters. Advantageously, provision is made to lay the rails 23 at the level of the threshold, the supports and the lintels of the facade 4. The uprights 21 can extend over the entire height of the facade 4, that is to say up to approximately 3 meters, without requiring any particular tool. The uprights 21 are arranged regularly, for example at the ends of the facade 4, in alignment with the door and window frames, then in equivalent subdivisions between the uprights 21 already laid. For example, the uprights 21 are arranged in such a way as to ensure a maximum center distance of 60 cm between two adjacent uprights 21.

[0171] Additionally, provision is made for the temporary installation of a platform 5 forming scaffolding, and allowing access to an upper portion of the facade 4. The platform 5 is thus temporarily assembled in certain notches 14 of the uprights 21. It is understood here that the assembly of the platform 5 simply corresponds to its insertion into the notches 14. The platform 5 is also stiffened by metal rods 51, illustrated in figures 11 and 12, forming corbels. The rods 51 make it possible to prevent the platform 5 from being unstable due to its cantilevered assembly.

[0172] The platform 5 thus makes it possible to serve as scaffolding, that is to say as a support, for the subsequent operations of installing the cladding 3. Thus, as illustrated in [Fig. 11], from the platform 5, additional rails 23 and uprights 21 are installed, corresponding to the rails 23 and uprights 21 arranged at a height greater than 2 meters and which could not have been installed previously, in particular the rail 23 at the upper end of the facade 4 and the uprights 21 above the doors and / or windows. The length of such uprights 21 can be adapted by cutting, from a standard-sized blade 1.

[0173] The first insulator 24 can then be arranged between the rails 23, for example by sliding behind the uprights 21 or by cutting it into a plurality of strips whose width is defined by the uprights 21 and the length defined by the rails 23.

[0174] One or more of the subsequent steps described with respect to figures 6 to 8 can then be carried out, in particular from the platform 5, for the portion of the covering 3 accessible from this platform 5.

[0175] The crosspieces 22 are thus placed on the uprights 21. So that the crosspieces 22 extend over the entire length of the facade 4, without requiring a blade 1 of dimension too large, for example, a set of fishplates and / or dowels is provided to allow the assembly of sleepers 22 arranged at the same height. The same type of fishplate assembly can also be considered for the rails 23, in order to limit their length.

[0176] Once the crosspieces 22 have been laid, the second insulators 25, the panels 26, and the sheets 28 can also be laid, on the accessible portion of the cladding, as illustrated in [Fig. 12]. These elements are for example laid as described with reference to Figures 5 to 9. In particular, the laying of the sheets 28 comprises at least the laying of the coping, at the upper end of the cladding 3.

[0177] Once all the elements in the upper portion have been assembled, the platform 5 is removed, and the rest of the cladding 3 is then also installed, as illustrated in [Fig. 13]. It is understood here that the exact separation between the elements installed from the platform 5 and the elements installed once the platform 5 has been removed may vary depending on the particularities of the facade 4, the exact position of the platform 5, and the relative ease of access to each element. However, there is no particular difference, structural or in terms of installation means, between the part of the cladding 3 installed from the platform 5 and the part of the cladding 3 installed once the platform 5 has been removed. Once the platform 5 has been removed and the rest of the cladding 3 installed, the installation of the cladding 3 on the facade 4 is complete.

[0178] The example of Figures 15 to 18 describes another method, which can at least partially repeat the steps of the method described in Figures 5 to 9. This example concerns a method of indirect installation on a wall of a cladding 3 of a facade 4, that is to say a method in which the cladding 3 is at least partially assembled before its installation on the facade 4. More precisely, Figures 15 to 17 describe in detail different phases of the indirect installation method, [Fig. 18] illustrating the complete sequence of the steps of the method.

[0179] In particular, such an indirect installation method can be implemented with respect to any facade template, and takes advantage of the use of scaffolding and / or lifting means, in particular by professionals. This method can be implemented in the direct vicinity of the facade 4, i.e. in situ, or at least partially at a distance from the facade, i.e. off-site.

[0180] As stated previously, this method comprises the establishment of a scaffolding 6 along the facade 4. This scaffolding is advantageously offset from the facade 4 by a distance greater than the thickness of the cladding 3. This design thus makes it possible to ensure that the cladding 3 can be placed on the facade 4 in the presence of the scaffolding 6. Obviously, the scaffolding 6 remains sufficiently close to the facade 4 to allow interaction with it.

[0181] Once the scaffolding 6 is installed, according to the example of [Fig.15], rails 23 are laid. For example, a rail 23 is planned to be laid at the threshold of facade 4, then at each level of facade 4, at the level of the slab noses. Each pair of rails 23 is thus associated with a floor, with a dimension of approximately 3 meters. It is therefore possible to divide the subsequent steps by floor, and to repeat them floor by floor, taking the rails 23 as a reference.

[0182] As illustrated in [Fig. 16], the first insulator 24 is placed between the rails 23, for example like the generic method with respect to [Fig. 5], similarly providing fixing rosettes 241. This design therefore corresponds to a direct installation of the first insulator 24 on the rails 23. According to another variant, it is possible to envisage an assembly of the first insulator 24 with the rest of the covering 3, for example via fixing claws like the second insulators 25.

[0183] In accordance with the concept of indirect installation, and in this same example, a projection 41 of the facade 4 is carried out on a remote platform 7, for example a platform of a truck equipped with lifting means 8, or on any other suitable surface close to the facade 4. The projection 41 is for example carried out at least partially by laser means, for example rulers equipped with lasers allowing precise transfer of the dimensions of the facade 4 on the remote platform 7. The projection 41 can also be carried out at least partially by manually recording the dimensions of the facade 4. Here, the lateral ends of the facade 4, as well as those of the door and window openings of the facade 4, are transferred by a laser trace, while the heights of the supports and lintels are recorded manually.

[0184] The remote platform 7 thus serves as a reference for the installation of all the elements of the cladding 3, for example for carrying out the steps described with regard to figures 6 to 9 of the generic method.

[0185] In other words, the uprights 21 are arranged on the offset platform 7 according to the projection 41, for example by following the position of the lasers. The uprights 21 are for example held in position by wedges arranged on the offset platform 7. Similarly, the crosspieces 22 are placed on the uprights 21 according to the projected dimensions, in particular according to the height of the rails 23, the supports and the lintels of the facade 4. The uprights 21 and the crosspieces 22 then form a base and a reference for the installation of the subsequent elements, in particular the second insulators 25, the panels 26 and the sheets 28, according to the example of figures 7 and 8. In accordance with the concept of the invention, all of the assembly steps of the cladding 3 from the slats 1 can be carried out close to the facade 4, on the offset platform 7, without requiring specialized tools.

[0186] All of these steps thus make it possible to obtain the covering 3 of [Fig.17], which is then placed on the remote platform 7. As illustrated in this figure, the assembled cladding 3 is then lifted via lifting means 8, so as to arrange it between the scaffolding 6 and the facade 4, then fixed on the rails 23. It can be seen here that, as stated previously, the cladding 3 is associated with a pair of rails 23, that is to say with a level of the facade 4, so as to limit the constraints on the lifting means and the dimensions of the offset platform 7. The above steps can thus be repeated for each pair of rails 23 of the facade 4, until a complete cladding 3 of the facade 4 is obtained, as illustrated by [Fig. 18].

[0187] Thus, it will be understood that the present invention provides a framework blade for producing facade cladding, a kit comprising a set of framework blades, a set of panels allowing the production of ventilated cladding, as well as a plurality of methods using such framework blades, allowing the production of a framework suitable for receiving insulation and sealing means, by simplifying as much as possible the production of this framework so that it can be assembled directly on or near the facade, without requiring assembly prior to transporting the assembled framework to the installation site of the facade cladding.

[0188] It should be noted that this detailed description relates to a particular embodiment of the present invention, but that in no case does this description have any limiting character with respect to the subject of the invention; on the contrary, its objective is to remove any possible imprecision or any misinterpretation of the claims which follow.

[0189] It should also be noted that the reference signs placed in parentheses in the following claims are in no way limiting; these signs have the sole purpose of improving the intelligibility and understanding of the following claims as well as the scope of the protection sought.
