Description

GLASS PANEL DEVICE AND ASSOCIATED IMPLEMENTATION METHOD

TECHNICAL AREA

The present invention falls within the field of building construction and relates to a glazed panel device.

The invention will find its application in the installation of panels, in particular on the facade of a building, preferably of the curtain wall type.

Remember that the generic term "curtain wall" corresponds to a light-type facade, ensuring the closure of the envelope of a building, without participating in its load-bearing structure. A curtain wall comprises a plurality of independent walls intended to be interconnected by a frame or "frame", said frame being mounted on the structure of the building.

Further on, the invention relates specifically to a panel device whose walls are glazed, hereinafter also referred to as “glazed panel”.

At present, there is a wide variety of glazed panels, with different frames and walls, depending on the construction to be made, which must withstand many constraints, in particular linked to bad weather such as rain and wind, earthquakes, fire and explosion, and air infiltration and exfiltration. In addition, the panels must ensure acoustic and thermal insulation, in order to limit noise pollution as well as energy losses between the exterior and the interior of the building.

In this context, an existing glazed panel comprises at least two glazed walls, separated by a cavity.

PRIOR TECHNIQUE

It will be noted that each glazed wall or “glazing” can be single, double or triple with several spaced panes, or even laminated with several joined sheets. In the case of double or triple glazing, the assembly of the panes makes it possible to obtain insulating characteristics, in particular by creating a vacuum or introducing an inert gas within the hermetically sealed space located between the windows. Glazing can be reinforced, tempered or even laminated. In addition, a glazing can be transparent or translucent, tinted, or even opaque, or even reflective, by treatment during the manufacture of the panes or of the glazing itself.

A glazed panel therefore comprises at least one outer wall, essentially subject to climatic constraints, and an inner wall, in contact with the internal environment of the building, such as in particular the heating and air conditioning. The cavity makes it possible to compensate for the differences in behavior between the walls faced with their respective constraints, serving as a separating buffer between the exterior and the interior of the building. In particular, a known glazed panel comprises at least two outer and inner walls fixedly mounted on the various elements of the frame, parallel to each other. In particular, the frame may comprise elements, fixed to the structure of the building or between them, forming a spacer which ensures parallelism between the glazings. Due to this parallelism, a glazed panel undergoes specific acoustic and thermal stresses, in particular according to the incidence of the forces considered.

First of all, considering the acoustic stresses undergone by the outer wall, the incident waves are likely to pass through the glazing and penetrate the cavity, generating a sound nuisance which is passed on to the inner wall. This penetration is all the greater when the angle of attack is normal with respect to the outer face of the outer wall, which is often the case when installing a glazed panel vertically. In order to limit the noise level of this nuisance, the current solution consists in increasing the thickness of the panes of the exterior wall, or even adding panes, in an attempt to attenuate the penetration. This results in a considerable additional cost, in financial terms but also in energy consumption at the time of manufacture. In addition, the panel is all the heavier, requiring the frame to be adapted accordingly.

In order to limit the angle of incidence from the outside, there is a glazed panel, the inner wall of which is inclined with respect to the vertical outer wall, as described in document BE 676 258, the glazing of which comprises an inner pane inclined with respect to a vertical outer pane. The cavity formed between the walls converges towards an internal side of said cavity, directing the sound waves coming from the interior towards this side. Therefore, an insulating material is placed along this side, directly or within a closed cell, ensuring the attenuation of the acoustic waves towards which they are directed and enclosed.

Moreover, considering the thermal constraints, in the event of a significant temperature difference between the inside and the outside of the building, increasing the glazing remains a recommended solution, as well as the addition of thermal insulation placed essentially on the the periphery of the cavity in the case of translucent glazing, or even a break in the thermal bridges between the elements of the frame supporting the outer wall and the inner wall. Taking these aspects into account considerably complicates the installation of glazed panels, increasing the related costs accordingly.

Relatedly, during the superposition of several glazings within the same panel, the cumulative mass makes it necessary to increase the resistance of the lower panels and, in fact, the thickness of the glazed walls. In addition, the internal pressure applies a horizontal and transverse force to approximately one third of the total height of the glass panel. In order to avoid deformation of the lower glazing, one solution therefore consists in distribute this load through the frame, which complicates the design and installation of such a panel.

DISCLOSURE OF THE INVENTION

The present invention aims to overcome the drawbacks of the state of the art by proposing to improve the behavior between the outer and inner walls, in particular in the face of the acoustic and thermal stresses undergone by each of them.

To do this, the invention relates to a glazed panel device for a building of which at least the outer wall has an inclination with respect to the longitudinal median plane of said panel. Firstly, this inclination makes it possible to provide a cavity having a converging section, having the effect of guiding towards one edge of the panel at least the acoustic waves passing through the outer wall, just as well as those originating from the interior.

In addition, said edge comprises a planned cell communicating with the internal volume of the cavity between the outer and inner walls, as well as emerging at an opening towards the outside. This open cell makes it possible to channel the acoustic waves, but also to attenuate them through a sound absorber implanted at the level of said cell.

In addition, in order to limit the penetration of external waves through the open cell and to ensure the outward circulation of the waves channeled by the cavity and attenuated during their passage through the cell, advantageously, the invention provides for 'installing shields according to a specific layout and design, attached to the outside and/or inside of the fixing frame of the outer and inner walls.

Thus, the invention can provide sound shields, in the outer part facing said opening of the cell. In addition, the specific layout and design of such sound shields ensure, on the one hand, an orientation of the acoustic waves during their expulsion from said cell and, on the other hand, protection against external waves, to prevent their penetration from the outside to the inside of said cell. In addition, the orientation and implantation of the sound shields between them generates a zone of depression, with respect to the external incident waves, improving the extraction of the acoustic waves from the cell and the interior towards the exterior.

Thus, alternatively or in combination, the invention can provide heat shields, in the interior part facing the lower part of the interior wall. In addition, the specific layout and design of such heat shields ensure protection of the air coming from the interior of the room towards the loss surface of said interior wall, thus impacting the natural rise of the air flow along the along this inner wall. Indeed, the invention takes into consideration the mass of the air in the room, essentially depending on its height, which induces a horizontal force from the inside outwards, this force being essentially located in the lower third of said part, according to a transposition of Coulomb's theory of active pressure or "earth pressure", often referred to as "Coulomb's triangle". This horizontal force applied to the air mass creates a horizontal flow in the lower part of the room, oriented towards the glazed panel.

Thus in position a heat shield in the lower part and along the inner wall, the induced air flow is diverted, limiting heat loss in contact with said inner wall.

In addition, such heat shields also make it possible to redirect part of the sound waves coming from inside the room.

To do this, according to the invention, the glazed panel device for a building comprises

- at least one exterior glazed wall,

- at least one interior glazed wall,

- a frame for fixing said exterior glazed wall and said interior glazed wall with a structure of said building, said fastening frame forming a cavity between said exterior glazed wall and said interior glazed wall,

- at least said outer glazed wall being inclined with respect to a longitudinal median plane of said panel,

- said cavity being oriented convergently towards an edge of said panel,

- at least one cell communicating with said cavity at said edge and emerging at an opening towards the outer wall, said cell being provided with at least acoustic insulation.

The device is characterized in that it comprises:

- at least one sound and/or heat shield,

- said at least one shield being implanted in the upper and/or lower part of said frame,

- Said at least one shield being oriented towards the center of said device, along a slope widening with respect to said longitudinal median plane of said panel.

According to additional, non-limiting characteristics, said cavity can be oriented convergently towards the upper edge of said panel.

According to one embodiment, said at least one shield comprises a section with a flared section from an end for fixing with said armature, towards with a distal end.

Said distal end may include a concave edge.

The device may comprise a sound shield implanted externally and in the upper part of said frame, said fixing end being mounted on said reinforcement, above the opening of the cell, said sound shield being oriented downwards, covering said opening.

Said sound shield can also comprise a diffuser, said diffuser being mounted on said frame, below the opening of said cell, said diffuser being oriented towards the distal end of said sound shield.

The device may comprise a heat shield being implanted internally and in the lower part of said frame.

Said interior glazed wall may be vertical or inclined with respect to the longitudinal median plane.

Said opening of the cell can be closed by a loss surface.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to building construction and is aimed at the installation of panels, in particular on the facade of a building, preferably of the curtain wall type.

To this end, the invention relates to a panel device 1 for a building.

Specifically, the invention relates to a glazed panel device 1, hereinafter also referred to as “device” or “glazed panel”.

Therefore, the device 1 comprises at least one outer glass wall 2 and at least one inner glass wall 3. In addition, the device 1 comprises an interior glazed wall 3 for each exterior glazed wall 2 . The walls 2.3 are located vis-à-vis one another, their largest surface facing each other.

According to different embodiments, the device 1 can comprise several superposed and/or contiguous walls 2,3, namely arranged respectively in columns or rows.

Preferably, the device 1 comprises an exterior glazed wall 2 and an interior glazed wall 3, thus forming a module with only two walls 2.3.

Each of the walls 2.3 can be single glazing, double or triple glazing with several spaced panes, or even a laminate of several joined sheets. In the case of double or triple glazing, the assembly of the panes makes it possible to obtain insulating characteristics, in particular by creating a vacuum or introducing an inert gas within the hermetically sealed space located between the windows. Glazing can be reinforced, tempered or even laminated. In addition, a glazing can be transparent or translucent, tinted, or even opaque, or even reflective, by treatment during the manufacture of the panes or of the glazing itself.

Thus, the device 1 can be a panel in the form of double glazing, or even more, or else of which each of the walls 2,3 are formed of single, double or triple glazing. In addition, the walls 2.3 can be identical or different, in particular with identical or different dimensions.

In addition, the device 1 comprises a frame 4, also referred to as a "chassis". This reinforcement 4 secures said at least one exterior glazed wall 2 and said at least one interior glazed wall 3 with a structure 100 of said building. The armature 4 thus provides the mechanical connection between the walls 2.3, in particular their bracing. Said fixing frame 4 thus provides a cavity 5 between the exterior glazed wall 2 and the interior glazed wall 3,

Furthermore, in the case of a panel 1 forming double glazing, the reinforcement 4 can form peripheral edges of said panel 1 .

Such a frame can be solid or perforated. It includes suitable elements and materials, ensuring good performance between the walls 2.3. Such elements may in particular be beams, angles or brackets. These elements can be made of any type of material, in particular plastic, composite or preferably metallic material.

In addition, the reinforcement 4 makes it possible to attach the panel 1 to the structure 100 of the building, such as for example the floor, the entresol, the walls or the ceiling, or even corresponding construction elements.

Thus, the armature may comprise members shaped to, on the one hand, be secured with the structure 100 and, on the other hand, ensure the fixing of the panel 1, in particular of each of its walls 2.3.

In particular, the armature 4 may comprise members 40 intended to receive the edges of the walls 2,3.

Examples of such members 40 are shown in particular in Figures 3 to 9. The members 40 are then in the form of U-shaped rails and dimensioned to allow the insertion and maintenance of an edge of each wall 2,3 .

The frame 4 can also comprise other elements, in particular for connecting several panels 1 between them, or else several exterior glazed walls 2 between them, or else several interior glazed walls 3 between them.

Advantageously, the invention provides for improving the performance of the panel 1 by tilting one of the walls 2.3. In particular, the invention provides at least one inclination of the exterior glazed wall 2 3 with respect to said panel 1 . In short, the walls 2.3 are not parallel to each other.

In addition, the inclination of the outer glazed wall 2 3 with respect to said panel 1 makes it possible either to keep the heat inside the room, or to leave the heat outside the room and thus to cool it. The inclination of the exterior glazed wall 2 also improves the sound insulation of said panel 1. This limitation of heat loss, this heating of the room or this cooling of the room make it possible to achieve considerable energy savings.

Preferably, the panel 1 is characterized in that said exterior glazed wall 2 3 is inclined with respect to said longitudinal median plane of said panel 1 . Such a median plane is shown schematically in dotted lines in FIGS. 2 to 9. Such a plane extends along the length, namely the longest axis, of said panel 1 . This plane also passes through the center of said panel 1, giving it its median character. According to the examples shown in the figures, said median plane extends vertically.

More specifically, according to one embodiment, the outer glass wall 2 is inclined with respect to the inner glass wall 3. Figures 3 to 5 show different embodiments, where the inner glass wall 3 extends vertically, parallel to said then vertical median plane, while the outer glass wall 2 is inclined convergently towards said glass wall 3 interior, with an upward-facing convergence.

According to another embodiment, the walls 2, 3 are inclined with respect to the longitudinal median plane of the panel 1. FIG. 6 shows an embodiment, where the walls 3, 4 are both inclined, in particular symmetrically with respect to in the middle plane. In short, the angle of inclination of the exterior glazed wall 2 is equal or substantially equal to the angle of inclination of the interior glazed wall 3. Panel 1 then has a cavity 5 with a trapezoidal section, forming a funnel.

According to another possibility, the walls 2, 3 can be inclined asymmetrically with respect to the median plane, namely that their respective angle of inclination is different with respect to said plane.

According to yet another embodiment, it is the entire panel 1 which has an inclination, namely that its median plane is not vertical. Therefore, one and / or the other of the walls 2.3 can be inclined relative to said axis. Figure 7 shows a configuration where the inner glass wall 3 is parallel to the median plane of the panel 1, itself inclined relative to the vertical, while the outer glass wall 2 is inclined relative to said median plane, and therefore by relative to said interior glass wall 3.

Further forward, said at least one exterior glazed wall 2 and/or said at least one interior glazed wall 3 is mounted for fixing by said frame 4 according to an inclination of between three degrees and thirty degrees with respect to said at least one glazed wall 2 exterior.

According to different embodiments, said inclination can be 5, 7.5, 10, 15, 20 or 25 degrees.

Remember that one grade corresponds to 0.9 degrees. Therefore, the inclination can be: - 5 grades, i.e. 4.5 degrees;

- 7.5 grades, i.e. 6.75 degrees;

- 10 grades, i.e. 9 degrees;

- 15 grades, i.e. 13.5 degrees;

- 20 grades, i.e. 18 degrees; Or

- 25 degrees, or 22.5 degrees.

Therefore, said cavity 5 is oriented convergently towards an edge of the panel 1, as shown in Figure 1.

As can be seen in the embodiments represented in FIGS. 3 and 4, the cavity 5 is oriented convergently towards an edge of said at least one exterior glazed wall 2, preferably the upper edge 20 .

As can be seen in the figures, the cavity 5 is oriented convergently towards an edge of said at least one exterior glazed wall 2, preferably its upper edge 20 .

As can be seen in FIG. 6, the cavity 5 is oriented convergently towards the adjacent edges of said at least one exterior glass wall 2 and of said at least one interior glass wall 3, in particular their respective upper edges.

Such an orientation makes it possible to orient any flux penetrating the cavity 5 from the outside by crossing the exterior glazed wall 2, in particular an acoustic wave. In particular, as shown in Figure 3, a wave striking the outer face of the outer glazed wall 2, in particular with an incidence normal to said outer wall 2, can cross it in a lesser way and come to bounce against the inner face. inclined from the inner glazed wall 3, to be guided along the converging direction of the cavity 5, until reaching the level of the edge 20 of the outer wall 2. In short, the acoustic wave is directed towards one side of the panel 1, instead of constraining the interior glass wall 3 .

In addition, the inclination of the exterior glazed wall 2 (combined or not with the inclination of the interior wall 3) makes it possible to limit, or even cancel, the generation of acoustic interference, originating in particular from the combination by overlapping of several successive incident sound waves, such as reverberations or echoes.

Further, the edge 20 can be equipped with means ensuring the absorption of the acoustic wave thus channeled.

To do this, the panel device 1 advantageously comprises at least one cell 6 communicating with said cavity 5 at the level of said edge 20. In addition, as can be seen in the embodiments represented in FIGS. 2 to 7, the cell 6 is shaped to connect the walls 2.3 to the levels of the edge 20 of the inner glass wall 3 and the corresponding edge of the outer glass wall 2. Cell 6 has globally a rectangular parallelepiped or trapezoidal prism shape, open on one side located at the level of the converging side of the cavity 5.

Preferably, as seen in Figures 3 to 7, the cell 6 has a wider spacing section than the spacing section of the cavity 5 at its convergent end. This narrowing of the cavity 5 followed by a widening formed by the cell 6, generates a so-called "venturi" effect, guiding and accelerating the flows, like the acoustic waves carried by the air, along the cavity 5 according to its convergent direction, then effecting an expansion of said flows within cell 6.

In particular, due to the fact that the cavity 5 communicates directly with the cell 6, the air and the acoustic waves are guided along the converging slope, circulating freely without obstacle, to be channeled and retained in the cell 6 in view of their attenuation. In addition, this communication opening limits any overpressure effect between the walls 2.3, in particular during the circulation of a sound wave.

The acoustic wave is therefore guided by the convergence of the cavity 5, therefore penetrates within the cell 6. In addition, said cell 6 is provided with at least one acoustic insulation 60, making it possible to attenuate the sound power of the acoustic wave which crosses said cell 6. In short, the acoustic insulation 60 is located inside the cell 6.

Such acoustic insulation can be a covering made of a suitable material, capable of absorbing certain frequencies of an acoustic wave.

In addition, according to the invention the cell 6 opens out at an opening towards the outer wall (3). In particular, such a cell 6 may include a permeable side 61, in order to allow the circulation of air, while canceling certain frequencies of the residual acoustic wave having passed through said cavity 5. Thus, the cell 6 acts trap, recovering the acoustic waves to lock them in, while allowing air to circulate between cell 6 and the outside of the building.

According to one embodiment, said opening of the cell (6) is closed by a loss surface. The latter can be made of any type of material, permeable to acoustic waves, but at least partially ensuring their attenuation.

According to one embodiment, as seen in Figure 2, the panel device 1 comprises at least one additional outer glass wall 7 superimposed on said at least one outer glass wall 2. In addition, said at least one additional exterior glazed wall 7 is oriented parallel to said at least one interior glazed wall 3 . In short, only the outer glazed wall 2, located below, is inclined. In addition, according to the configuration shown in Figure 2, the cell 6 can be positioned between the edge 20 of the outer glazed wall 2 located below and the lower edge of said additional glazed wall 7 located above. According to another configuration, the upper edge 20 of the exterior glazed wall 2 opens at the level of the lower edge of the additional glazed wall 7 and the cell 6 is then offset and positioned communicating with the upper opposite edge of this additional glass wall 7.

According to another embodiment, not shown, the additional glazed wall 7 is also inclined, according to a degree of inclination similar or identical to the exterior glazed wall 2. In this case, the additional wall 7 can also comprise a corresponding additional cell, in particular at its upper edge.

From a thermal point of view, advantageously, the inclination of at least the exterior glazed wall 2 ensures better circulation of the thermal fluxes circulating inside the room where the panel device 1 is installed. The example of FIG. 2 highlights a circulation of thermal fluxes, represented by an arrow to the left, in particular under the action of heating or air conditioning means present within said room. These flows are turbulent but have a globally rotating direction, so that they come to slide along the inner face of the then inclined inner glazed wall 3, instead of confronting it in the case of a vertical wall.

Indeed, depending on the degree of inclination of the interior glazed wall 3, the invention makes it possible to modify the incidence of the thrust force generated horizontally towards the interior glazed wall 3. In particular, such a thrust force is generated due to thermal attraction, in particular in the case of a temperature difference greater than 2 degrees Celsius (°C) measured between said wall 3 and the environment of the part. The inclination of said wall 3 induces that this force no longer pushes the mobile heat flux of the part normally, but at an angle, which reduces the losses passing through said fixed interior glazed wall 3.

In addition, the thrust towards the inner wall 3 results from the mass of air, according to Coulomb's theory, inducing a horizontal force in the lower third of the part, pressing against said inner wall 3. Due to the inclination of the outer wall 2, combined or not with the inclination of the inner wall 3, this induced Coulomb force is redirected, modifying the air flow conditions inside the room. , thus improving thermal insulation.

The invention thus makes it possible to obtain a gain from the point of view of thermal insulation.

This being so, in order to improve the sound and/or thermal insulation already acquired due to the inclination of at least the outer wall 2, the invention provides for the installation of sound shields 8 and/or sound shields 9 respectively. thermal.

To do this, the device 1 of the glazed panel comprises at least one sound shield 8 and/or at least one thermal shield 9. In addition, said at least one shield 8.9 comprises a profile. Such a profile extends along the width of the panel 1. Said profile can be made of any type of material, preferably plastic, metal or composite.

In addition, said profile has a flared section from an end for fixing with said frame 4, to with a distal end 80,90. In short, the profile of the shield 8.9 is thicker at its free end than at its end for attachment to the panel 1.

Said edge of the distal end 80,90 can be of any shape.

According to one embodiment, as seen in Figures 3 to 9, said distal end 80,90 comprises a concave edge. The shield section 8.9 then generally has the shape of a golf tee.

Regarding the sound insulation, the device 1 comprises a sound shield 8 implanted externally and in the upper part of said frame 4.

In addition, said fixing end is mounted on said frame 4, above the opening of cell 6.

In addition, said sound shield 8 is oriented downwards, covering said opening.

Therefore, the sound shield 8 makes it possible to deflect a part of the acoustic waves coming from the outside, by protecting the opening of the cell 6. This deviation makes it possible to limit the acoustic waves likely to penetrate into the cell 6 via its opening, ensuring that the waves channeled from inside the panel 1 propagate and come out attenuated by said opening. This deviation and the channeling of sound waves is represented in particular by corresponding arrows in Figure 2.

According to one embodiment, said phonic shield8 comprises a diffuser81. Several examples of a sound shield 8 with a diffuser 81 are shown in Figures 3 to 7.

In addition, said diffuser 81 is mounted on said frame 4, below the opening of said cell 6. In short, the diffuser 81 is another profile, attached under the profile of the sound shield 8, or else connected at regular intervals with the profile of said sound shield 8, through an openwork structure.

Said profile of the diffuser 81 can have any shape, in particular with a hollow or concave lower edge, as visible in Figures 6 to 7.

In addition, said diffuser 81 is oriented towards the distal end of said shield 8 phonic. In short, the diffuser 81 forms a step towards the outside, limiting the rise of the acoustic waves along the outer wall 22 and preventing their penetration into the cell 6 via its opening. According to a preferred embodiment, shown in Figure 7, the sound shield 8, as well as its diffuser 81, comprise profiles with specific rounded shapes, improving the flow of acoustic waves.

Relatedly, the sound shield 8 also makes it possible to limit the penetration of air flow from the outside to the inside of the cell 6, limiting heat loss in this direction.

As such, concerning the thermal insulation, the device 1 comprises a shield? implanted internally and in the lower part of said frame 4. Like the sound shield 8, the heat shield 9 is therefore oriented towards the center of the device 1, widening from its end of attachment with the frame 4 towards its distal end 90. In short, the heat shield 9 is turned upwards, generally forming a V with the inner wall 3 at the level of the base of the glazed panel 1, as visible in the two embodiments of Figures 8 and 9.

In addition, the heat shield comprises a profile which may have a shape and a section similar to that of the profile of the sound shield.

Therefore, due to its configuration, the heat shield 8 makes it possible to push back, from the base of the panel 1, the flow of air coming from inside the room, in particular induced by the horizontal force resulting from Coulomb's theory . As modeled in Figure 2, the air is deflected inward, diverting the rest of the airflow located above. Thus, the contact of the air stirred in this way with the interior wall 3 is disturbed, limiting the heat losses. In addition, this disturbance thus generated makes it possible to deflect the internal acoustic waves and to limit their transmission to the interior wall 3 of said panel 1 .

According to one embodiment, the panel device 1 comprises at least one member for heating or cooling said cavity 5. Such a heating or cooling member can be connected to a dedicated and independent means, report within the building, in particular at the level of the room where one or more devices 1 of panels are installed. In addition, the heating or cooling member can emerge at one of the edges of the cavity 5, in order to ensure the circulation therein of a heated or cooled flow from said dedicated means.

The example of FIG. 2 shows a heating flux circulating towards the cavity 5 via said heating or cooling member, then located in the lower position of said panel 1, at the level of the junction with the structure 100 of the building.

Furthermore, from a structural point of view, the inclination of at least the exterior glazed wall 2, in particular in the low position of a panel 1, makes it possible to considerably lighten the structure of the curtain wall, composed of one or more superimposed panels 1. In fact, the inclination transfers upwards the force originating from the combined mass of the panels 1 and/or of the external glazed walls 2 in superposition. He is then possible to reduce the resistance of the materials, in particular to reduce the thickness and the weight of the corresponding glazing.

Thus, through its glazed panel device 1, the invention makes it possible to improve the acoustic and thermal performance of the curtain wall attached to a building, while offering a reduced total mass for the materials used.
