Definitions

  • the present invention relates to interior panels of light ventilated facades of buildings comprising bays.
  • ventilated light facades are well known. They are appreciated for their excellent technical performance, in particular with regard to thermal insulation, the wide variety of choice of exterior cladding and their easy removal. Exterior facings can, in fact, be removed and replaced quickly and cleanly, totally or partially, and at low cost, without affecting the use of the buildings and without disturbing their occupants.
  • the interior wall is generally a masonry wall or a reinforced concrete veil.
  • the present invention aims to provide interior panels of ventilated light facades which are themselves light and whose construction provides a simple and inexpensive bay frame as is the case in the construction of ventilated light facades whose wall interior is heavy, in masonry or reinforced concrete.
  • Another object of the invention is to allow the systematic, easy and economical construction of bays of very different dimensions.
  • Another object of the invention is to allow the combination of an interior panel with window, which resists corrosion by atmospheric agents, which is mechanically resistant and which may optionally include a frame frame incorporated in the interior panel.
  • Another object is to provide a light interior wall, easy to provide with means of thermal insulation, not itself presenting a thermal bridge, offering by itself a seal both at water and at vapor. water and allowing easy realization of the ventilated air knife.
  • Another object is to facilitate, simplify, rationalize and make modular the manufacture and assembly of the interior wall and its mounting on the framework.
  • Another object of the invention is to make ventilated light facades even more easily removable and interchangeable, partially or totally, than are the known light facades.
  • the present invention relates to an interior panel of ventilated light facade provided with at least one opening.
  • This interior panel has stylized vertical C-shaped profiles having a central back panel to which are connected, at right angles, two side panels themselves carrying a rim at right angles, the two rims being directed towards each other. .
  • These vertical profiles, juxtaposed and assembled to each other by their side panels, are interrupted at the location of the bay.
  • the interior panel thus formed is reinforced by stiffening profiles fixed along the horizontal edges of the interior panel and of the opening.
  • the series of dorsal sections of the vertical profiles forms a continuous dorsal sheet intended to be fixed to the framework of a building.
  • the edges of the vertical C profiles are intended to carry an exterior facing of the ventilated light facade.
  • the inner panel comprises, vertical profiles whose back panels are of different widths, for example 30, 45 and 60 cm.
  • the appropriate juxtaposition of profiles of different widths thus allows the production of panels of various dimensions themselves provided with bays of the desired width, which may differ from one panel to another.
  • the height of the opening is defined by a simple choice of the length of the profiles, depending on the height required above and below the opening for the lintel and for the sill. It is thus possible to produce panels and bays of various dimensions without there ever being any loss of material, which is economically very important.
  • the profiles used can be made of various materials including metal.
  • these profiles are preferably made of composite material comprising polymers and reinforcing materials. This choice of material makes it possible to produce interior panels which are light while being mechanically resistant, and also makes it possible to avoid thermal bridges between the exterior and the interior of the building.
  • the profiles of composite material can easily be assembled together, in particular by gluing.
  • the polymers can be chosen from a very wide range of plastics, such as, for example, unsaturated polyesters, poly (vinyl chloride), polyimide and polycarbonate.
  • the reinforcing materials can also be of various kinds. These are, in general, fibers, for example glass or carbon fibers.
  • the first C profiles, made of reinforced plastic are produced by pultrusion.
  • the vertical C-shaped profiles preferably have an extra thickness at the point of their edges and at the part of the back panel situated opposite.
  • these extra parts the inertia of which is thus increased, form with the lateral sections profiles reinforced in I which allow the interior panel to better withstand dynamic stresses of pressure and depression generated by the wind and the static stresses generated by the more or less significant weight of the exterior facings.
  • a layer of insulating material covers the central back panel inside each vertical section in C.
  • the thickness of this insulating layer is less than the width of the side panels, so as to create a space constituting a vertical air gap between the insulation layer and the exterior facing which will be fixed in front of the interior panel.
  • the lateral sections of the vertical profiles in C have a rib directed towards the interior of the C. These ribs hold in place, in front of the layer of insulating material, a flexible sheet of a material different from that of the layer insulation, for example an aluminum sheet, thereby improving the sound insulation.
  • the central back panel of the vertical C-shaped sections is formed two or more parallel sheets joined together by the side panels.
  • the space provided between these parallel sheets is filled with an acoustic and thermal insulating material, for example a polymer foam or rock wool.
  • These parallel sheets which form the dorsal side of the vertical C-shaped profiles may possibly all be an integral part of the profile (which is preferably pultruded). However, it is also intended that only the sheet located furthest back forms an integral part of the vertical section in C, the sheet (or sheets) located (s) further forward being slid (s) in place between the side panels, in small slides provided for this purpose. In this case, it is advantageous to produce this sheet (or these sheets) in a material different from that of the profile itself, so as to improve the sound insulation.
  • the central dorsal section of the vertical C-shaped sections is formed from more than two parallel sheets (for example three sheets)
  • the spaces between the successive sheets can be filled with different insulating materials, which further improves the sound insulation.
  • the interior panel further comprises T-shaped profiles, of pultruded composite material, fixed vertically against its dorsal face at the junction points of the vertical C-shaped profiles, thus strengthening the connection between these vertical profiles.
  • a thin sheet or plate (for example a sheet or a thin fiber-cement plate) can be fixed against these T-profiles, parallel to the back panels of the vertical C profiles. The space between this sheet or plate and said back panels can be filled with an acoustic and thermal insulating material.
  • the lateral sections of the vertical C-shaped sections as well as the stiffening sections may be provided with sections facing the inside of the bay, forming a pattern in F. All of these patterns in F form a double window sash.
  • the stiffening profiles fixed along the horizontal edges of the interior panel and the opening are preferably made of composite material and formed by pultrusion. They are preferably box profiles and the space included in these profiles can be filled with a thermal and acoustic insulating material.
  • the lower horizontal profile of the opening can be extended by a window sill.
  • the interior panel further comprises horizontal load-bearing profiles fixed against the edges of the vertical C-shaped profiles and intended to hang there elements of external facing of the light ventilated facade.
  • the present invention also relates to a light ventilated facade which comprises interior panels as defined above.
  • the junction between the interior panels can be made by means of U-shaped profiles made of a flexible and waterproof material, these U-shaped profiles pressing against flat beats fixed to the rear edges of the interior panels. .
  • the space between these U-shaped profiles is filled with thermal and acoustic insulating material.
  • the invention relates to a light ventilated facade which includes interior panels as defined above, provided with horizontal support profiles to which are attached exterior facing elements.
  • the invention also relates to a method of constructing an interior panel of a ventilated light facade provided with at least one opening.
  • stylized C-shaped profiles are manufactured, which profiles have a central dorsal panel to which are connected, at right angles, two lateral panels themselves carrying a flange at right angles, the two edges being directed towards each other.
  • Such C-profiles of the same length are juxtaposed and at the place provided for a bay, shorter C-sections are inserted which frame the bay above and below. All the C sections are assembled together, side panel against side panel, all the back panels of these sections being arranged in the same plane. Stiffeners are then fixed to the upper and lower edges of the panels, as well as to the upper and lower edges of the opening.
  • the C profiles are advantageously produced by pultrusion of a composite material.
  • the central back panel is covered inside each C-shaped section with a layer of insulating material, the thickness of which is less than the width of the side panels.
  • T-shaped profiles are fixed against the dorsal face of the interior panel, parallel to the direction of the C profiles and at the places of their junction, strengthening the connection between them; the space between the successive T-profiles is filled with an acoustic and thermal insulating material and a sheet is fixed against the T-profiles.
  • the interior panels according to the invention have many advantages.
  • the profiles which compose them are made of composite material, they have at the same time a low weight, a good mechanical resistance and a low conductivity thermal.
  • the thickness of the vertical profiles varies according to the dynamic and static stresses to which its various parts are subjected, which allows to combine maximum stability with a minimum of material used.
  • the shape of the vertical profiles ensures good rigidity of the interior panel in the vertical direction.
  • the rigidity of the panel in the horizontal direction is ensured not only by the horizontal stiffening profiles but also by the fact that the panel is fixed at several points to horizontal elements of the frame of the building.
  • the panels are waterproof against rain, wind and water vapor and allow varying degrees of sophistication in thermal and sound insulation.
  • the manufacture of the interior panels separately from the exterior facing allows the mounting of exterior facing very diverse in nature, shape, relief and dimensions, even in the facades of the same building. It can be thin stones, marbles, granites, ceramics, aluminum or steel sheets, plastics, fiber cement sheets, etc.
  • the mounting of these facings on the interior panel can possibly be carried out in the workshop.
  • the interior panels according to the invention very advantageously replace the interior wall which in traditional heavy construction generally consists of a masonry wall or a reinforced concrete veil.
  • the prefabricated elements according to the invention can be used very advantageously for the production of ventilated light facades for buildings whose main structure is constructed by means of modular construction units, and in particular for buildings whose large work is done according to the technique described in European patent No. 0 012 736.
  • the interior panels according to the invention can be mounted, in the workshop, on modular construction units. If necessary, horizontal load-bearing profiles and possibly the exterior facing can be attached to the interior panels.
  • the face of the interior wall facing the interior of the building can be concealed by another wall, similar to the interior partitions of the building, which makes the appearance of the dorsal face of the interior wall irrelevant and is likely to further strengthen the acoustic and thermal insulation of facades.
  • the junction between panels and the sealing of the interior facing can be carried out as follows.
  • U-shaped sections of flexible but impervious material are fixed to these ends by gluing or screwing, and the space comprised in these U-shaped sections is filled with thermal insulating material.
  • FIG. 1 is an exploded view of a portion of a traditional ventilated light facade.
  • Fig. 2 is a horizontal section and
  • FIG. 3 is a vertical section through part of the facade shown in FIG. 1.
  • a heavy frame 1 of reinforced concrete carries a filling 2 of reinforced concrete or masonry which forms a heavy interior wall comprising openings 3.
  • insulating panels 5 are placed, which are cut at the location of the openings 3.
  • Horizontal load-bearing profiles are fixed on the vertical load-bearing profiles 4 6.
  • Cover plates 7 forming the external facing are fixed to the horizontal support profiles 6.
  • the insulating panels 5 have a thickness which is less than the height of the vertical profiles 4 in I thus leaving between the insulating panels 5 and the covering plates 7 a space 8 which allows natural vertical ventilation, specific to the light ventilated façades.
  • Fig. 4 is an exploded view of an interior panel with opening, according to the invention, intended to carry an exterior facing to form together a light ventilated facade.
  • Fig. 5 is a horizontal section and FIG. 6 a vertical section of a portion of ventilated light facade whose inner panel is produced according to the invention.
  • Fig. 7 is a horizontal section and FIG. 8 is a vertical section through a window opening, like that of FIG. 4, in which the frames and glazing are not shown.
  • FIGS. 4 to 8 illustrate well that the interior panel 10 according to the invention alone and advantageously fulfills the same functions as reinforced concrete or masonry 2 and the aluminum profiles 4 shown in FIGS. 1 to 3.
  • Each vertical section 9 has a central back panel 11 to which are connected, at right angles, two side panels 12 themselves carrying a rim, at right angles. The two flanges 13 are directed towards each other.
  • the juxtaposition of several sections 9 in C, side by side, forms the panel 10.
  • the series of back panels 11 of the vertical sections 9 forms a continuous back sheet intended to be fixed to the frame of the building (not shown).
  • an upper stiffening profile 17 is fixed along the upper edge of the panel 10 which is a box profile, substantially in the form of a P.
  • a stiffening profile 18 is fixed, identical but reversed, along the lower edge of the panel 10.
  • a stiffening section 19 which forms a lintel underside
  • a stiffening section 20 which forms a light support
  • the space included in the stiffening profiles 17, 18, 19 and 20 is filled with a thermal and acoustic insulating material.
  • the stiffness of the interior panel 10 in the vertical direction is automatically ensured by the shape of the vertical profiles 9 which compose it, by virtue of the side panels 12 and the flanges 13.
  • An insulating material 21 covers the back panel 11 inside each section 9 at C, the thickness of the insulator 21 is less than the width of the side panels 12.
  • the free space left between the insulator 21 and the rim 13 constitutes a vertical ventilation air gap 8 along the opening of the profile 9 at C.
  • the edges 13 of the profiles 9 carry horizontal profiles 6 to which the outer facing 7 is fixed.
  • the interior panels 10 according to the invention are produced by juxtaposition of vertical profiles 9 in C allows a wide variety of dimensions of these panels 10 and those of the bays 14 which they comprise.
  • the width of these sections 9 can be varied so as to have a set of standard widths, for example 30, 45 and 60 cm.
  • Various combinations of these profiles 9 of different widths thus allow the production of interior panels 10 provided with bays 14 of very different widths, possibly in the same building.
  • the variation of the height of the bays it is obtained even more simply, by cutting, before assembly, profiles 9 in C at the desired length corresponding to the desired height 15 for the lintel above the bay 14 and at the desired height 16 for the lighters below the bay 14, to leave the bay 14 a free opening of the desired dimension.
  • Another advantage which results from the construction of interior panels from vertical profiles 9 in C in composite material is the fact that one is not obliged to stick to a uniform thickness of the material of said profiles.
  • a profile can be pultruded which, in addition, carries a rib 24 in the side panel 12 between the insulation panel 21 and the flange 22.
  • the rib 24 holds a sheet 25 against the surface of the insulation 21, for example aluminum foil. This arrangement gives the thermal insulating layer 21 a better ability to play at the same time an acoustic insulation role.
  • the interior panel 10 further comprises T-shaped profiles 26.
  • These profiles 26 of pultruded composite material are bonded against the dorsal face of the interior panel 10, at the junction points of the profiles 9 at C, thus strengthening the connection between these sections 9 and further increasing the rigidity of the interior panel 10.
  • the space between the successive sections 26 is filled with an acoustic and thermal insulating material 27.
  • This insulator 27 is covered with a thin wall 28 in sheet metal or fiber cement, for example.
  • FIG. 11 further clearly improves the acoustic and thermal insulation of the interior panel 10.
  • Figs. 12 and 13 show that by making a modification to the sections 9, 19 and 20 which frame a bay 14, it is possible to produce a window frame incorporated in the interior panel 10 itself.
  • the side panel 12 of the vertical section 9 at C which forms the vertical table of the window frame 14, has, at the location of the window 14, two sides facing inwards giving to the side panel 12 a profile 29 in the form of F.
  • the upper horizontal stiffening profile 19, forming a lintel, and the lower stiffening profile 20, forming a light support have patterns 29 in F. towards the interior of the opening 14. All of these patterns 29 at F form a window frame with double battée.
  • the lower horizontal stiffener profile 20 is extended by a window threshold or sill support 30 overhanging the exterior facing panel 7 and leaving a space 31 allowing the ventilation of the vertical air gap 8 along the vertical profiles 9 at C .
  • Fig. 14 is a horizontal section of a vertical profile 9 as can also be seen in FIG. 5. It is a stylized C-shaped profile, of which the central dorsal panel 11 consists of a single sheet.
  • the central dorsal panel of these vertical sections can however be formed from two or more sheets parallel to each other, connected by the side panels 12.
  • the central dorsal panel is formed by two sheets 33 and 34 parallel to each other.
  • the space between these sheets 33 and 34 is filled with an acoustic and thermal insulating material 35.
