Definitions
- the present invention belongs to the field of the construction of glazed facades for buildings, and relates more particularly to a seal for a curtain wall, as well as a curtain wall comprising such seals.
- the present invention finds a particularly advantageous application, although in no way limiting, in the case of a curtain wall delivered in separate parts and assembled on site.
- Such a waterproofing system must above all prevent the infiltration of water within the curtain wall, so that the structure of the curtain wall is not subject to humidity which, if it accumulates for an extended period, can be the cause of inconvenience: water infiltration directly into the interior environment, development of mold within the structure of the curtain wall, etc.
- a curtain facade comprises a frame formed by assembling mullion sections with crosspiece sections.
- This framework supports glazed elements of said curtain wall, typically double glazing taking the form of panels, for example rectangular panels.
- These glazed elements are in contact with seals fitted to the profiles in order to prevent water from penetrating.
- connection elements have been proposed between mullion sections and crosspiece sections.
- Such a connecting element forms an extension of a transom profile and is configured so as to allow the evacuation of moisture accumulated in said transom profile through drainage surfaces of a mullion profile to which the transom profile is connected.
- connection elements and associated with seals all substantially identical dimensionally and fixed on mullion and crosspiece sections of particular configurations.
- the joints of the transom profiles are only in contact with the joints of the mullion profiles at the level of the intersection zone, which contributes to the improvement of sealing, without making it optimal.
- the contact between two seals is all the more tight as said seals are compressed towards each other.
- the shape of the seals used hitherto does not favor obtaining sufficient compression to achieve optimum sealing, and this especially when the glazed elements are installed bearing against the seals.
- the present invention is defined by the characteristics of claim 1 and its objective is to remedy all or part of the drawbacks of the prior art, in particular those set out above, by proposing a solution which makes it possible to have a joint of seal for a curtain facade, said seal being adapted to promote excellent compression in the direction of another seal of the same type with which it is intended to be brought into contact at the level of a zone intersection of the curtain wall. Said seal also makes it possible to compensate effectively, over time, for the manufacturing tolerances of the curtain wall that it is intended to equip, as well as the deformations undergone by the structure of said curtain wall.
- the present invention aims to provide a curtain facade comprising such seals.
- the seal may also include one or more of the following characteristics, taken separately or in any technically possible combination.
- Said deformation means are a curved surface of said contact part, said curved surface extending between a first end common to the lateral junction face and a second end common to the lateral bearing face, so as to present a curvature oriented towards the fixing foot, said curved surface being inclined at least at the level of said first end by a non-zero angle ⁇ with respect to the horizontal, in the direction going from the fixing foot towards the contact part.
- said second end has the shape of a protruding tab.
- Said junction side face is inclined at a non-zero angle ⁇ with respect to the vertical, in the direction going from the support side face towards the junction side face.
- said lateral support face comprises a lug so as to form a support part positioned between said fixing foot and said lug, said support part being intended to be arranged in leaktight support against a edge of the drainage surface of the profile.
- said seal comprises means for aiding the cutting of said seal along a horizontal plane P positioned between said contact part and said fixing foot.
- said cutting aid means are at least one cell extending, in the plane P, over a predetermined distance along the length of said seal.
- the seal deprived of its fixing base is made of cellular EPDM foam.
- the invention relates to a curtain facade with the characteristics of claim 1.
- the curtain facade can also include one or more of the following characteristics, taken individually or in all technically possible combinations.
- the seal of a crosspiece profile extends over a length substantially greater than the length of said crosspiece profile.
- each profile comprises two seals cooperating respectively with two fixing grooves arranged on either side of said at least one drainage surface of said profile.
- each drainage surface comprises a rim resting on a fixing groove and extending in the direction of the glazed elements, said rim further comprising a return end so as to present an L-shape facing towards said drainage surface, said bearing part of each seal being arranged to bear tightly against the edge of the drainage surface of the profile fitted with said seal, so as to conform to said L-shape
- the present invention finds its place in the field of the construction of curtain walls for buildings, such as for example a building comprising housing or offices, and more particularly finds an application in the protection of such curtain walls against projections of water (or any other liquid) and moisture resulting from such splashes.
- FIG 1 schematically represents an exemplary embodiment of such a seal 100, and corresponds to a view in a cross section of said seal 100.
- the seal 100 as shown in the figure 1 is at rest, i.e. it is not deformed by any compressive force.
- Said seal 100 extends along a longitudinal axis, and along a predetermined length, between two ends which respectively have a cross section conforming to that illustrated in the figure 1 .
- transverse reference is therefore made here and for the rest of the description to a section along a plane normal to said longitudinal axis.
- the curtain facade with which the seal 100 is intended to cooperate comprises a framework formed by assembling mullion sections with crosspiece sections, said framework supporting glazed elements of said curtain façade.
- Each profile comprises, in a manner known to those skilled in the art, a fixing groove as well as a drainage surface.
- a geometric and mechanical configuration of the curtain wall is described in more detail later.
- the seal 100 includes a fixing foot 110 intended to cooperate with a fixing groove of a profile.
- said fixing foot 110 has an end taking the form of a mushroom with an inverted head and extending from a base which forms a face of the seal.
- the fixing foot 110 is also sized so that it can be clipped into the fixing groove of the profile, thus maintaining the seal 100 in a fixed position on the profile.
- said section with which the seal 100 is intended to cooperate can equally well be a mullion section or a cross section.
- the seal 100 is conventionally formed by extrusion, along its longitudinal axis, of extensible polymer materials, typically synthetic rubber.
- the seal 100 deprived of its fixing foot 110 is made of cellular EPDM (acronym for the ethylene-propylene-diene monomer formulation) foam.
- active part reference is made here to a part intended to undergo mechanical stresses, for example following a support exerted by a glazed element or even another contiguous seal, as well as configured, both in terms of shape and of materials used, to compensate for these constraints.
- the fixing foot 110 for its part, is for example made of compact EPDM material, which advantageously makes it possible to stiffen the seal 100 at the level of said fixing foot 110. It should be noted that a person skilled in the art knows produce a seal 100 consisting of materials having different respective densities. Alternatively, the seal 100 in its entirety is for example made of cellular EPDM foam.
- the seal 100 has an outer surface comprising a contact part 120 opposite said fixing foot 110 and intended to support a glazed element. More particularly, such a glazed element is planar in shape and is pressed, during the assembly of the curtain facade, against said contact part 120 which therefore crushes under the effect of this cladding due to the materials used for the realization of the seal 100, in particular its active part.
- the contact part 120 then tends to match the flat shape of the glazed element when the latter exerts a pressure directed from said contact part 120 towards the fixing foot 110.
- Said external surface comprises a lateral face, called junction 130, connecting said contact part 120 to said fixing foot 110. Furthermore, the external surface also comprises a lateral face, called support 140, connecting said contact part 120 to said fixing foot 110 and opposite to said lateral junction face 130, said lateral support face 140 being intended to be arranged on the side of a drainage surface of the profile. As shown on the figure 1 in no way limiting, said side faces 130, 140 are substantially parallel when the seal 100 is at rest.
- the notions of upper, lower, above, below, high, low, horizontal and vertical are defined with respect to the relative position of the fixing foot 110 with said contact part 120.
- the direction according to an axis connecting the fixing foot 110 to the contact part 120 is said to be vertical, the horizontal direction being for its part orthogonal to the vertical direction.
- the contact part 120 and the fixing foot 110 are arranged respectively at the upper level and at the lower level of the seal 100.
- the face of the seal 100 from which extends the fixing foot 110 is called the underside 150.
- the seal 100 comprises deformation means configured to extend substantially horizontally, in a cross section of said seal 100, said contact portion 120 at least in the direction going from the lateral bearing face 140 towards the lateral junction 130, when a pressure, substantially directed from said contact part 120 towards said fixing foot 110, is exerted on said contact part 120.
- extend here has the same meaning as the term “stretch”, so that the use of this or that term should not create confusion.
- Such deformation means thus make it possible to increase horizontally, by elastic deformation, the surface of the contact part 120, this deformation occurring, when said pressure is exerted, essentially at the upper level of the seal 100, namely its contact part 120. It should nevertheless be noted that due to its elastic composition, the active part of the seal 100, located beyond the contact part 120, is also likely to extend locally horizontally when said pressure is exercised. This being the case, the deformation means advantageously allow the deformation undergone by the contact part 120 to be substantially greater, in terms of horizontal distance, than that undergone by the rest of the active part of the seal 100.
- Such a configuration then makes it possible to obtain excellent sealing at the level of an intersection zone between a mullion section and a crosspiece section of the curtain wall, even more particularly in an interior corner of this zone in contact with a glazed element. Indeed, by stretching in this way, the seal 100 will be all the more compressed when faced with an obstacle located in its direction of stretching. Therefore, it is understood that if this obstacle is another seal, the compression between these two seals is greatly accentuated due to said deformation means.
- the deformation of the seal 100 also makes it possible to advantageously compensate for the manufacturing tolerances of the curtain wall that it is intended to equip, more specifically the dimensional tolerances of the mullion and transom profiles. This is further reinforced when the gasket is fixed to a mullion profile so as to be in contact with another seal fixed to a transom profile. Indeed, the relative movements of these two seals due to the compression generated by the deformation means make it possible to minimize the possible assembly deviations which could result from manufacturing errors, which in general can be of the order of a few millimeters in regarding the profiles of the facade.
- said deformation means are a curved surface of said contact part 120.
- Said curved surface extends between a first end 121 common to the side face of junction 130 and a second end 122 common to the side face of support 140, so as to present a curvature oriented towards the fixing foot 110.
- curvature oriented towards the fixing foot 110 reference is made here to the fact that the curved surface has a curvature whose center of curvature is outside to the seal 100.
- the contact part 120 thus shaped hollows the external surface towards the fixing foot 110.
- the contact part 120 has such a domed surface only when the seal 100 is at rest.
- the configuration of said contact part 120 not only aims for a horizontal stretch but also flattening along the stretch direction. Such flattening promotes better sealing at the level of contact with the glazed element.
- said curved surface is inclined at least at the level of said first end 121 by a non-zero angle ⁇ with respect to the horizontal, in the direction going from the fixing foot 110 towards the contact part 120.
- the inclination of such a slope is adapted so that the contact part 120 stretches in priority horizontally, in the direction going from the lateral face support 140 towards the lateral junction face 130.
- the angle ⁇ is included in the interval [15°, 35°] with respect to the horizontal (the horizontal and the inclination of the slope are shown in dotted lines on the figure 1 ), for example more particularly a value of 25°.
- said first end 121 is in the form of a point pointing upwards.
- Such a configuration thus allows the seal 100, when it is compressed and fixed on a profile of the curtain wall, to stretch first of all towards the outside of said profile.
- said second end 122 has the shape of a protruding tongue.
- said tab is substantially directed in the direction going from the lateral junction face 130 towards the lateral support face 140, said tab being further inclined with respect to the horizontal so as to point upwards and extend to the -beyond the lateral support face 140 according to a predetermined distance.
- Such a configuration of the second end 122 allows the contact part 120, when it is subjected to a pressure directed from said contact part 120 towards the fixing foot 110, to extend horizontally also in the direction going from the lateral face of junction 130 towards the lateral face of support 140. This is particularly advantageous when the seal 100 is fixed on a profile, because then said tab 122 makes it possible to narrow an air space located between the glazed element and the drainage surface, thereby slowing the passage of moisture from an external environment to said profile.
- the curved surface of the contact part 120 may have a horizontal slope at the level of the second end 122 so that the support side face 140 is substantially perpendicular to the contact part 120 at the level of said second end 122.
- said junction side face 130 is inclined at a non-zero angle ⁇ relative to the vertical, in the direction going from the support side face 140 towards the junction side face 130.
- said angle ⁇ has a value comprised in the interval [2°, 10°] when the seal 100 is not deformed (the vertical and the inclination of the lateral face of the junction are shown in dotted lines on the figure 1 ), for example more particularly a value of 3.5°.
- the lateral junction face 130 leans outwards, beyond a frame forming said profile.
- Such a configuration is particularly advantageous when it is combined with the means for deforming the seal 100.
- the inclination of the lateral junction face 130 allows, in itself, when the seal 100 is fixed on a mullion profile, to favor contact of the upper part of said joint 100 with another joint of a cross member profile connected to said mullion profile.
- the deformation means alone contribute to obtaining excellent sealing, it is understood that the combination of these means with an inclined junction side face 130 according to the invention contributes to obtaining optimum sealing. Indeed, once a joint of a mullion section has come into contact with a cross section of a crosspiece joint, via the lateral junction face 130 of said mullion joint, the deformation means will allow, pressure of the glazed element on the joints, that the joint of the mullion profile extends towards the joint of the crosses so as to increase the compression at their contact. The contact is then sealed by this increase in the level of compression.
- the junction side face 130 is flat. This is an advantageous configuration when the seal 100 equips a mullion section and is brought into contact with a seal of the same type of a cross section. Indeed, as explained above, when contact is established between these two joints, the reinforced compression obtained by the deformation means initially brings the joint of the mullion profile closer to the joint of the crosspiece profile at the level of the part top of the mullion seal. As the compression increases, and in a second step, the flat surface of the mullion joint also approaches the joint of the transom profile to end up pressing against the cross section of the latter, thus limiting any risk. moisture infiltration.
- said lateral support face 140 comprises a lug 141 so as to form a support part 142 positioned between said fixing foot 110 and said lug 141, said support part 142 being intended to be arranged in waterproof support against an edge of the drainage surface of the profile.
- a rim of the drainage surface is in particular configured so that hardware elements cooperate with the drainage surface.
- the lug 141 of the lateral support face 140 extends for example substantially normally to the lateral support face 140. In this way, when the rim of the drainage surface is configured substantially in the shape of an L, the part support 142 matches the shape of the rim, said lug 141 resting in tight support on a branch of the L.
- the seal 100 comprises means for aiding the cutting of said seal 100 along a horizontal plane P positioned between said contact part 120 and said fixing foot 110.
- Such means advantageously allow easy cutting of the seal 100 in said plane P so as to be able to remove a mass from said seal 100 (the plane P is shown in dotted lines in the figure 1 ). It is in fact understood that when a mass of substantially parallelepipedic shape must be removed from the seal 100, from the contact part 120, it is first necessary to cut the seal 100, over a distance allowing said cutting aid means, along substantially parallel cross sections. The respective executions of such notches are easy insofar as they are made from the contact part 120 which is directly accessible.
- the final cutting of the mass takes place at the level of the plane P which is less accessible than the contact part 120 insofar as it extends into an internal volume of the seal. 100, said internal volume being delimited by the external surface.
- said cutting aid means make it possible to cut the seal 100 more easily and more quickly at the level of the plane P.
- said cutting aid means are at least one cell 170 extending, in the plane P, over a predetermined distance along the length of said seal 100.
- said cutting aid means constitute a targeted recess of the seal 100 at the level of the plane P, which facilitates cutting due to a reduction in the resistance encountered against the elastic mass, and allows thus a clear and rapid execution in a privileged direction.
- the seal 100 comprises four contiguous cells 170 extending in the plane P along the longitudinal axis of said seal.
- the invention relates to a curtain facade comprising seals.
- FIG 2 schematically represents an embodiment of a portion 200 of a curtain facade, and corresponds to a perspective view from an observation point located in an external environment 10 of said curtain facade 200.
- the curtain wall comprises a frame formed by assembling mullion sections 210 with crosspiece sections 220, said frame supporting glazed elements 300 of said curtain wall.
- Said profiles 210, 220 are conventionally made by extrusion, for example from aluminum material.
- said mullion 210 and crosspiece 220 profiles are identical, which contributes to facilitating and accelerating the production of the elements necessary for the construction of the curtain wall.
- the framework of the curtain wall is for example assembled even before being delivered to the site, or for example still delivered to the site in separate parts to be assembled on site.
- the curtain facade thus formed separates the exterior environment 10 from an interior environment 20 (offices, living spaces, etc.) intended to accommodate people.
- picture 3 schematically represents an embodiment of a section of the portion 200 of the picture 2 , and corresponds to a view in a cross section of said profile.
- the mullion 210 and crosspiece 220 sections used to form the framework of the figure 2 are identical to each other.
- picture 3 therefore illustrates a mullion section 210, but it is easy to understand that the reference sign "210" of the picture 3 can be replaced by the reference sign "220" without this causing any confusion.
- the use of the term "profile” without it being specified whether it is a mullion profile or a cross member profile refers indiscriminately to one of these two types of profiles.
- the length of a profile 210, 220 then corresponds to the dimension of said profile 210, 220 counted along the axis normal to the cross section as illustrated in the picture 3 .
- Each profile 210, 220 comprises along its length at least one fixing groove 230 as well as at least one drainage surface 240. Such a configuration is known to those skilled in the art.
- each profile 210, 220 comprises two fixing grooves 230 arranged on either side of said at least one drainage surface 240 of said profile 210, 220.
- Each fixing groove 230 comprises two side faces 231, 232 interconnected by a base so as to have a general U-shape.
- One 231 of said side faces extends a face of the profile 210, 220 intended to be normal to the glazed elements 300.
- the other side face 232 of the fixing groove 230 is in turn resting against one end of the drainage surface 240, so that this other side face 232 is substantially normal to said drainage surface 240.
- the profile 210, 220 comprises a retaining groove 250 configured to receive a retaining element, such as for example a screw 251, said retaining element 251 making it possible to connect the profile 210, 220 in a fixed manner to an outer cover 400 so that the glazed elements 300 are held between said outer cover 400 and said profile 210, 220.
- a retaining element such as for example a screw 251
- the two fixing grooves 230 are interconnected by a surface from which extends normally, in the direction of the glazed elements 300, said holding groove 250. In this way, said surface is separated into two parts which respectively form two drainage surfaces 240.
- Each profile 210, 220 is equipped with at least one seal 100, so that the contact part 120 of a seal 100 is deformed by compression exerted by a glazed element 300.
- a seal 100 is fixedly arranged in a fixing groove 230 of a profile 210, 220 by inserting the fixing foot 110 of said seal 100.
- each profile 210, 220 comprises two seals 100 cooperating respectively with two fixing grooves 230 arranged on either side of said at least one drainage surface 240 of said profile 210, 220.
- the fixing foot 110 of a seal 100 is inserted by clipping between the side faces 231, 232 of a U-shaped fixing groove 230.
- each section includes two seals, one of said two seals of conventional configuration known up to now to those skilled in the art. It is however noted that the implementation for each profile of two seals according to the invention advantageously makes it possible to obtain optimum sealing at the level of each glazed element.
- THE figures 4a and 4b schematically represent an embodiment of a mullion section 210 connected with two crosspiece sections 220 to form the portion 200 of the picture 2 , and correspond to respectively grouped and exploded views of the assembly of these sections 210, 220.
- Each crosspiece profile 220 is connected in a substantially orthogonal manner to at least one mullion profile 210 by means of a connector 221 fixedly mounted at one connecting end 222 of said crosspiece profile 220, so as to extend said at least a drainage surface 240 of said cross-piece profile 230, said connecting end 222 then resting against said mullion profile 210.
- a connector 221 is fixedly connected to a cross-piece profile 220 in a manner known per se, for example by means of 'a screw.
- Such a connector 220 is known per se, and for example conforms to the connector described in the document EP2787138 .
- the connecting end 222 of a cross member profile corresponds to a cross section of said crosspiece profile 220 as illustrated for example in the picture 3 . It is also noted that when the crosspiece section 220 includes a retaining groove 250 as described above, the connector 221 is also advantageously configured to extend said retaining groove 250.
- said framework forms a frame of the grid type.
- Each mullion section 210 is then connected to one or two crosspiece sections 220 depending on whether said mullion section 210 is arranged on the edge or not of said grid.
- connectors 221 it is also possible to use, in a manner known per se, retaining pins to connect the mullion 210 and crosspiece 220 sections to each other.
- the facade portion 200 comprises a mullion section 210 substantially normal to the ground plane (not shown in the figures), two crosspiece sections 220 being further connected to said mullion section 210 on either side of the latter of so that said portion 200 has a cross shape delimiting four quadrants equipped with glazed elements 300.
- Said glazed elements 300 are panels of rectangular shape, each panel forming for example double glazing.
- a first pane then faces the outside environment 10, while a second pane, separated from the first pane by an air gap, faces the inside environment 20.
- Such intersection zones 500 are for example illustrated on the figure 4b (dashed circles).
- a seal 100 of a crosspiece profile 220 extends over at least the entire length of said crosspiece profile 220, so as to be in exclusive contact with a seal 100 of mullion profile 210.
- exclusive contact and as illustrated in the figure 4b , reference is made here to the fact that a joint 100 fitted to a crosspiece profile 220 has no point of contact with the very rigid structure (for example made of aluminum) of the mullion profile 210 with which said transom profile 220 is connected.
- the fact of having such an exclusive joint-to-joint contact is advantageous because it makes it possible to avoid multiple contacts between materials of different constitutions at the level of the connecting end 222 of the crosspiece profile 220, for example contacts between a gasket and aluminum. Indeed, such multiple contacts are known to be a limiting factor in sealing performance in the intersection area 500.
- the seals 100 of the mullion 210 and of the crosspiece 220 are for example configured so that they have respective side junction faces 130 of substantially identical dimensions.
- the vertical heights of the seals 100, at their respective side junction faces 130, are identical.
- the seal 100 of a crosspiece profile 220 extends over at least the entire length of the crosspiece profile 220 allows said seal 100 to have a cross section which, at a minimum, flush with a connecting end 222 of said crosspiece profile 220.
- Such a configuration makes it possible to engage the contact with the seal 100 located opposite on the mullion profile 210 connected to said crosspiece profile 220.
- the contact part 120 of the mullion seal 210 is stretched due to the support provided by the glazed element 300, it is understood that the two seals 100 come into contact by compressing each other at the level of the intersection zone 500. A such compression is moreover accentuated when at least the lateral junction face 130 of the joint 100 of the mullion profile 210 is inclined by a non-zero angle ⁇ , as explained above in detail.
- a seal 100 of a crosspiece section 220 extends over a distance substantially greater than the length of the crosspiece section 220.
- the difference in length between the seal 100 and the crosspiece profile 220 is of the order of a few centimeters, for example a difference comprised in the interval [1cm, 3cm], for example more particularly 2cm.
- Such a configuration allows the joint 100 of the crosspiece profile 220 to extend slightly beyond the fixing end 222 of said crosspiece profile 220, so as to bring the end of the joint 100 of the transom even closer to the contact portion 120 of the mullion joint.
- the mutual compression obtained between the crosspiece joint and the mullion joint is further advantageously reinforced.
- each seal 100 of a mullion profile 210 includes a notch 160 configured to cooperate, in compression along said seal 100, with the connector 221 connecting said mullion profile 210 to a cross member profile. 220.
- a notch 160 therefore forms a recess in which the connector 221 is housed so as to be in contact with the entire surface of said notch 160. It is important to note that by "notch”, reference is made here to a part recessed which does not entirely cross the seal 100. In other words, the mullion seal comprising such a notch 160 remains in one piece.
- said notch 160 is substantially U-shaped, so that it corresponds to the release of a substantially parallelepipedic mass from the joint 100 of the mullion section 210. It is for example obtained by transverse cuts in the joint 100 of the mullion 210, then by cutting along a plane P (said plane P is horizontal with reference to the figure 1 ). To this end, when the joint 100 of the mullion section 210 comprises cutting aid means, the production of the notch 160 is facilitated.
- the cutout along said plane P defines a base of the notch against which the connector 221 is arranged. More particularly, the connector 221 is pressed against said base so as to compress it, which advantageously contributes to increasing the sealing at the level of the contact between the connector 221 and the base.
- the fact that the notch 160 is configured to cooperate with the connector 221 in compression along said seal 100 also makes it possible to obtain an excellent seal at the level of the contacts established between the connector 221 and the surface of the notch 160 which is not parallel to the longitudinal axis of the seal 100.
- the base of the notch 160 connects two cross sections of the seal 100 of the mullion section 210.
- the connector 221 then cooperates with the notch 160 so as to be in sealed contact with said two cross sections.
- the length of the base, counted in the direction of the longitudinal axis of the seal 100, is substantially less (for example by a few millimeters, typically 5mm to 10mm) than the dimension of the connector 221 along this same axis. In this way, the connector 221 is held in the notch 160 by compression between said cross sections of the gasket 100.
- each drainage surface 240 comprises a rim 241 resting on a fixing groove 232 and extending in the direction of the glazed elements 300, said rim 241 further comprising a return end so as to present an L-shape facing towards said drainage surface 240.
- Said bearing part 142 of each seal 100 is arranged to bear tightly against the edge 241 of the drainage surface 240 of the profile equipped with said seal 100, so as to conform to said L-shape
- the support part 142 also has an L-shape thanks to the presence of the lug 141.
- the fact that the support part 142 of the joint 100 comprises a lug 141 so to cooperate with the L-shape of said rim 241 makes it possible to increase the seal at the level of the support of the seal 100 with the drainage surface 240. Indeed, if the rim does not include a return and if the part of support does not have a lug, moisture could infiltrate between the support part and the rim.
- such a configuration of the rim 241 of the drainage surface 240 advantageously allows the cooperation of hardware elements which are thus kept fixed with the profile 210, 220 at the level of the drainage surface 240.
- said elements hardware are glazing support plates, fixed to the crosspiece profiles 220 and substantially normal to the drainage surfaces 240 of these profiles.
- a curtain facade fitted with seals according to the invention has optimum and long-lasting sealing performance, said seals also making it possible to effectively compensate, during the time, the manufacturing tolerances of said curtain wall, as well as the deformations undergone.

Description
La présente invention appartient au domaine de la construction de façades vitrées pour bâtiments, et concerne plus particulièrement un joint d'étanchéité pour une façade rideau, ainsi qu'une façade rideau comportant de tels joints d'étanchéité. La présente invention trouve une application particulièrement avantageuse, bien que nullement limitative, dans le cas d'une façade rideau livrée en pièces détachées et assemblée sur chantier.The present invention belongs to the field of the construction of glazed facades for buildings, and relates more particularly to a seal for a curtain wall, as well as a curtain wall comprising such seals. The present invention finds a particularly advantageous application, although in no way limiting, in the case of a curtain wall delivered in separate parts and assembled on site.
Actuellement, il existe différents types de systèmes d'étanchéité destinés à assurer l'étanchéité à l'eau (ou tout autre liquide) d'une façade rideau qui sépare un environnement extérieur d'un environnement intérieur (bureaux, pièces de vie, etc.) que la façade rideau vise à protéger.Currently, there are different types of sealing systems intended to ensure the watertightness (or any other liquid) of a curtain facade which separates an external environment from an internal environment (offices, living rooms, etc.). .) that the curtain wall aims to protect.
Un tel système d'étanchéité doit avant tout empêcher l'infiltration d'eau au sein de la façade rideau, afin que la structure de la façade rideau ne soit pas sujette à une humidité qui, si elle s'accumule pendant une durée étendue, peut être à l'origine de désagréments : infiltration d'eau directement au sein de l'environnement intérieur, développement de moisissures au sein de la structure de la façade rideau, etc.Such a waterproofing system must above all prevent the infiltration of water within the curtain wall, so that the structure of the curtain wall is not subject to humidity which, if it accumulates for an extended period, can be the cause of inconvenience: water infiltration directly into the interior environment, development of mold within the structure of the curtain wall, etc.
De manière conventionnelle, une façade rideau comporte une ossature formée par assemblage de profilés de meneaux avec des profilés de traverses. Cette ossature supporte des éléments vitrés de ladite façade rideau, typiquement un double vitrage prenant la forme de panneaux, par exemples des panneaux rectangulaires. Ces éléments vitrés sont en contact avec des joints équipant les profilés afin d'empêcher l'eau de pénétrer. S'il apparait clairement que le problème de l'étanchéité se pose au niveau de l'ensemble des contacts réalisés entre un élément vitré et les joints équipant les profilés, il n'en reste pas moins que la zone située à l'intersection d'un profilé de meneau et d'un profilé de traverse reste la plus sensible. En effet, il s'agit là d'une zone dans laquelle différents éléments s'interconnectent (profilés, joints, éléments vitrés), si bien que de multiples contacts entre ces éléments sont créés et fragilisent d'autant l'étanchéité de la façade rideau.Conventionally, a curtain facade comprises a frame formed by assembling mullion sections with crosspiece sections. This framework supports glazed elements of said curtain wall, typically double glazing taking the form of panels, for example rectangular panels. These glazed elements are in contact with seals fitted to the profiles in order to prevent water from penetrating. Although it is clear that the problem of sealing arises at the level of all the contacts made between a glazed element and the seals fitted to the profiles, the fact remains that the zone located at the intersection of a mullion profile and a transom profile remains the most sensitive. Indeed, this is an area in which different elements interconnect (profiles, seals, glazed elements), so that multiple contacts between these elements are created and weaken the sealing of the facade accordingly. curtain.
Aussi, afin d'étanchéifier à l'eau une construction de ce type, plusieurs solutions ont été proposées jusqu'à présent. Il a par exemple été proposé des éléments de raccord entre profilés de meneau et profilés de traverse. Un tel élément de raccord forme une extension d'un profilé de traverse et est configuré de sorte à permettre l'évacuation de l'humidité accumulée dans ledit profilé de traverse par des surfaces de drainage d'un profilé de meneau auquel le profilé de traverse est relié.Also, in order to waterproof a construction of this type, several solutions have been proposed so far. For example, connection elements have been proposed between mullion sections and crosspiece sections. Such a connecting element forms an extension of a transom profile and is configured so as to allow the evacuation of moisture accumulated in said transom profile through drainage surfaces of a mullion profile to which the transom profile is connected.
Toutefois, si ces solutions mettant en oeuvre de tels éléments de raccord ont certes permis d'améliorer sensiblement l'étanchéité d'une façade rideau, il n'en reste pas moins qu'elles présentent des désavantages. En effet, du fait de leur conception, de tels éléments de raccord nécessitent généralement l'emploi de joints coupés au niveau des angles formés entre les profilés de meneau et de traverse. Il est alors impératif d'injecter une masse étanche, comme par exemple du mastic, au niveau de jonctions entre les joints coupés de sorte à garantir une étanchéité suffisante. Il en résulte une mise en oeuvre générale compliquée, la bonne injection de la masse étanche étant notamment difficile à contrôler. Alternativement, pour se passer d'une telle masse étanche, un joint formant un cadre est soudé dans lesdits angles. Néanmoins, une telle mise en oeuvre est contraignante dans la mesure où des joints de ce type sont produits à la demande en fonction des dimensions des chantiers, s'opposant ainsi à une solution d'étanchéité qu'on souhaite la plus générique et la plus simple possible.However, if these solutions implementing such connecting elements have certainly made it possible to substantially improve the sealing of a curtain wall, the fact remains that they have disadvantages. Indeed, because of their design, such connecting elements generally require the use of joints cut at the angles formed between the mullion and crosspiece sections. It is then imperative to inject a waterproof mass, such as putty, at the level of the junctions between the cut joints so as to guarantee sufficient sealing. This results in a complicated general implementation, the correct injection of the sealed mass being in particular difficult to control. Alternatively, to do without such a sealed mass, a joint forming a frame is welded in said corners. Nevertheless, such an implementation is restrictive insofar as seals of this type are produced on demand according to the dimensions of the sites, thus opposing a sealing solution which is desired to be the most generic and the most as simple as possible.
En outre, de telles solutions ont toutes pour inconvénient de mettre en contact, au niveau de la zone d'intersection, des éléments de dureté différente, notamment des joints équipant les profilés de traverse en contact direct avec des profilés de meneau. De tels contacts sont connus pour ne pas favoriser une bonne étanchéité.In addition, such solutions all have the drawback of bringing into contact, at the level of the intersection zone, elements of different hardness, in particular seals fitted to the crosspiece sections in direct contact with the mullion sections. Such contacts are known not to promote good sealing.
Plus récemment, de nouveaux systèmes d'étanchéité ont été développés. Ces derniers mettent encore en oeuvre des éléments de raccord améliorés, et associés à des joints tous sensiblement identiques dimensionnellement et fixés sur des profilés de meneau et de traverse de configurations particulières. Selon ces configurations, les joints des profilés de traverse sont uniquement au contact des joints des profilés de meneau au niveau de la zone d'intersection, ce qui contribue à l'amélioration de l'étanchéité, sans pour autant la rendre optimale. En effet, le contact entre deux joints est d'autant plus étanche que lesdits joints sont compressés l'un vers l'autre. Or la forme des joints utilisés jusqu'à présent ne favorise pas l'obtention d'une compression suffisante pour atteindre une étanchéité optimale, et ce tout particulièrement lorsque les éléments vitrés sont installés en appui contre les joints. Par ailleurs, la compression atteinte lors du montage de la façade rideau est altérée par des déformations de l'ossature, en raison de contraintes mécaniques et thermiques subies dans le temps, ainsi que par les tolérances de fabrication qui restent inévitables. Ces nouveaux systèmes d'étanchéité ne sont donc pas en mesure de fournir une étanchéité optimale pérenne.
La présente invention est définie par les caractéristiques de la revendication 1 et elle a pour objectif de remédier à tout ou partie des inconvénients de l'art antérieur, notamment ceux exposés ci-avant, en proposant une solution qui permette d'avoir un joint d'étanchéité pour façade rideau, ledit joint d'étanchéité étant adapté à favoriser de manière pérenne une excellente compression en direction d'un autre joint d'étanchéité de même type avec lequel il est destiné à être mis en contact au niveau d'une zone d'intersection de la façade rideau. Ledit joint d'étanchéité permet également de compenser efficacement, au cours du temps, les tolérances de fabrication de la façade rideau qu'il se destine à équiper, ainsi que les déformations subies par la structure de ladite façade rideau. La présente invention vise à proposer une façade rideau comportant de tels joints d'étanchéité.The present invention is defined by the characteristics of claim 1 and its objective is to remedy all or part of the drawbacks of the prior art, in particular those set out above, by proposing a solution which makes it possible to have a joint of seal for a curtain facade, said seal being adapted to promote excellent compression in the direction of another seal of the same type with which it is intended to be brought into contact at the level of a zone intersection of the curtain wall. Said seal also makes it possible to compensate effectively, over time, for the manufacturing tolerances of the curtain wall that it is intended to equip, as well as the deformations undergone by the structure of said curtain wall. The present invention aims to provide a curtain facade comprising such seals.
Dans des modes particuliers de réalisation, le joint d'étanchéité peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises isolément ou selon toutes les combinaisons techniquement possibles.In particular embodiments, the seal may also include one or more of the following characteristics, taken separately or in any technically possible combination.
Lesdits moyens de déformation sont une surface bombée de ladite partie de contact, ladite surface bombée s'étendant entre une première extrémité commune à la face latérale de jonction et une seconde extrémité commune à la face latérale d'appui, de sorte à présenter une courbure orientée vers le pied de fixation, ladite surface bombée étant inclinée au moins au niveau de ladite première extrémité d'un angle α non nul par rapport à l'horizontale, dans le sens allant du pied de fixation vers la partie de contact.Said deformation means are a curved surface of said contact part, said curved surface extending between a first end common to the lateral junction face and a second end common to the lateral bearing face, so as to present a curvature oriented towards the fixing foot, said curved surface being inclined at least at the level of said first end by a non-zero angle α with respect to the horizontal, in the direction going from the fixing foot towards the contact part.
Dans un mode particulier de réalisation, ladite seconde extrémité présente une forme de languette faisant saillie.In a particular embodiment, said second end has the shape of a protruding tab.
Ladite face latérale de jonction est inclinée d'un angle θ non nul par rapport à la verticale, dans le sens allant de la face latérale d'appui vers la face latérale de jonction.Said junction side face is inclined at a non-zero angle θ with respect to the vertical, in the direction going from the support side face towards the junction side face.
Dans un mode particulier de réalisation, ladite face latérale d'appui comporte un ergot de sorte à former une partie d'appui positionnée entre ledit pied de fixation et ledit ergot, ladite partie d'appui étant destinée à être agencée en appui étanche contre un rebord de la surface de drainage du profilé.In a particular embodiment, said lateral support face comprises a lug so as to form a support part positioned between said fixing foot and said lug, said support part being intended to be arranged in leaktight support against a edge of the drainage surface of the profile.
Dans un mode particulier de réalisation, ledit joint d'étanchéité comporte des moyens d'aide à la découpe dudit joint d'étanchéité selon un plan P horizontal positionné entre ladite partie de contact et ledit pied de fixation.In a particular embodiment, said seal comprises means for aiding the cutting of said seal along a horizontal plane P positioned between said contact part and said fixing foot.
Dans un mode particulier de réalisation, lesdits moyens d'aide à la découpe sont au moins une alvéole s'étendant, dans le plan P, sur une distance prédéterminée dans la longueur dudit joint d'étanchéité.In a particular embodiment, said cutting aid means are at least one cell extending, in the plane P, over a predetermined distance along the length of said seal.
Dans un mode particulier de réalisation, le joint d'étanchéité privé de son pied de fixation est réalisé en mousse EPDM cellulaire.In a particular embodiment, the seal deprived of its fixing base is made of cellular EPDM foam.
L'invention concerne une façade rideau avec les caractéristiques de la revendication 1.The invention relates to a curtain facade with the characteristics of claim 1.
Dans des modes particuliers de réalisation, la façade rideau peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises isolément ou selon toutes les combinaisons techniquement possibles.In particular embodiments, the curtain facade can also include one or more of the following characteristics, taken individually or in all technically possible combinations.
Dans un mode particulier de réalisation, le joint d'étanchéité d'un profilé de traverse s'étend sur une longueur sensiblement supérieure à la longueur dudit profilé de traverse.In a particular embodiment, the seal of a crosspiece profile extends over a length substantially greater than the length of said crosspiece profile.
Dans un mode particulier de réalisation, chaque profilé comporte deux joints d'étanchéité coopérant respectivement avec deux rainures de fixation agencées de part et d'autre de ladite au moins une surface de drainage dudit profilé.In a particular embodiment, each profile comprises two seals cooperating respectively with two fixing grooves arranged on either side of said at least one drainage surface of said profile.
Dans un mode particulier de réalisation, chaque surface de drainage comporte un rebord en appui sur une rainure de fixation et s'étendant en direction des éléments vitrés, ledit rebord comprenant en outre une extrémité de retour de sorte à présenter une forme en L tournée vers ladite surface de drainage, ladite partie d'appui de chaque joint d'étanchéité étant agencée en appui étanche contre le rebord de la surface de drainage du profilé équipé par ledit joint, de sorte à épouser ladite forme en LIn a particular embodiment, each drainage surface comprises a rim resting on a fixing groove and extending in the direction of the glazed elements, said rim further comprising a return end so as to present an L-shape facing towards said drainage surface, said bearing part of each seal being arranged to bear tightly against the edge of the drainage surface of the profile fitted with said seal, so as to conform to said L-shape

La présente invention trouve sa place dans le domaine de la construction de façades rideaux pour bâtiments, comme par exemple un immeuble comportant des logements ou bien des bureaux, et trouve plus particulièrement une application à la protection de telles façades rideaux face à des projections d'eau (ou tout autre liquide) et à l'humidité résultant de telles projections.The present invention finds its place in the field of the construction of curtain walls for buildings, such as for example a building comprising housing or offices, and more particularly finds an application in the protection of such curtain walls against projections of water (or any other liquid) and moisture resulting from such splashes.

Ledit joint d'étanchéité 100 s'étend suivant un axe longitudinal, et selon une longueur prédéterminée, entre deux extrémités qui présentent respectivement une section transversale conforme à celle illustrée dans la
La façade rideau avec laquelle le joint d'étanchéité 100 est destiné à coopérer comporte une ossature formée par assemblage de profilés de meneau avec des profilés de traverse, ladite ossature supportant des éléments vitrés de ladite façade rideau. Chaque profilé comporte, de manière connue de l'homme du métier, une rainure de fixation ainsi qu'une surface de drainage. Une telle configuration géométrique et mécanique de la façade rideau est décrite plus en détails ultérieurement.The curtain facade with which the
Le joint d'étanchéité 100 comporte un pied de fixation 110 destiné à coopérer avec une rainure de fixation d'un profilé. Tel qu'illustré sur la
Rien n'exclut cependant, suivant d'autres exemples non détaillés ici, d'avoir un pied de fixation 110 de forme différente (rectangulaire, carrée, triangulaire, etc...) dès lors qu'il est adapté à faire coopérer de manière fixe le joint d'étanchéité 100 avec la rainure de fixation d'un profilé.Nothing excludes however, according to other examples not detailed here, to have a fixing
Le joint d'étanchéité 100 est classiquement formé par extrusion, selon son axe longitudinal, de matières polymères extensibles, typiquement du caoutchouc synthétique. Dans un exemple préféré de réalisation, le joint d'étanchéité 100 privé de son pied de fixation 110 est réalisé en mousse EPDM (acronyme de la formulation éthylène-propylène-diène monomère) cellulaire. On note que la partie du joint 100 correspondant au joint privé de son pied de fixation 110 forme une partie active. Par « partie active », on fait référence ici à une partie destinée à subir des contraintes mécaniques, par exemple suite à un appui exercé par un élément vitré ou bien encore un autre joint contigu, ainsi que configurée, aussi bien en termes de forme et de matériaux employés, pour compenser ces contraintes. Le pied de fixation 110, quant à lui, est par exemple réalisé en matériau EPDM compact, ce qui permet avantageusement de rigidifier le joint d'étanchéité 100 au niveau dudit pied de fixation 110. Il est à noter que l'homme du métier sait réaliser un joint d'étanchéité 100 constitué de matériaux présentant des densités respectives différentes. Alternativement, le joint d'étanchéité 100 dans son entièreté est par exemple réalisé en mousse EPDM cellulaire.The
Le joint d'étanchéité 100 comporte une surface externe comprenant une partie de contact 120 opposée audit pied de fixation 110 et destinée à recevoir en appui un élément vitré. Plus particulièrement, un tel élément vitré est de forme plane et est plaqué, lors du montage de la façade rideau, contre ladite partie de contact 120 qui s'écrase donc sous l'effet de ce plaquage en raison des matériaux employés pour la réalisation du joint d'étanchéité 100, notamment de sa partie active. La partie de contact 120 tend alors à épouser la forme plane de l'élément vitré lorsque ce dernier exerce une pression dirigée de ladite partie de contact 120 vers le pied de fixation 110.The
Ladite surface externe comporte une face latérale, dite de jonction 130, reliant ladite partie de contact 120 audit pied de fixation 110. Par ailleurs, la surface externe comporte aussi une face latérale, dite d'appui 140, reliant ladite partie de contact 120 audit pied de fixation 110 et opposée à ladite face latérale de jonction 130, ladite face latérale d'appui 140 étant destinée à être agencée du côté d'une surface de drainage du profilé. Tel qu'illustré sur la
Pour la suite de la description, les notions de supérieur, inférieur, dessus, dessous, haut, bas, horizontal et vertical sont définies par rapport à la position relative du pied de fixation 110 avec ladite partie de contact 120. Ainsi, la direction selon un axe reliant le pied de fixation 110 à la partie de contact 120 est dite verticale, la direction horizontale étant quant à elle orthogonale à la direction verticale. De cette manière, la partie de contact 120 et le pied de fixation 110 sont agencés respectivement au niveau supérieur et au niveau inférieur du joint d'étanchéité 100. En outre, la face du joint d'étanchéité 100 à partir de laquelle s'étend le pied de fixation 110 est dite face inférieure 150.For the rest of the description, the notions of upper, lower, above, below, high, low, horizontal and vertical are defined with respect to the relative position of the fixing
Le joint d'étanchéité 100 comporte des moyens de déformation configurés pour étendre sensiblement horizontalement, dans une section transversale dudit joint d'étanchéité 100, ladite partie de contact 120 au moins dans le sens allant de la face latérale d'appui 140 vers la face latérale de jonction 130, lorsqu'une pression, sensiblement dirigée de ladite partie de contact 120 vers ledit pied de fixation 110, est exercée sur ladite partie de contact 120. On note que le terme « étendre » a ici la même signification que le terme « étirer », de sorte que l'emploi de tel ou tel terme ne saurait créer de confusion.The
De tels moyens de déformation permettent ainsi d'accroitre horizontalement, par déformation élastique, la surface de la partie de contact 120, cette déformation se produisant, lorsque ladite pression est exercée, essentiellement au niveau supérieur du joint d'étanchéité 100, à savoir sa partie de contact 120. Il faut néanmoins noter qu'en raison de sa composition élastique, la partie active du joint 100, située au-delà de la partie de contact 120, est également susceptible de s'étendre localement de manière horizontale lorsque ladite pression est exercée. Cela étant, les moyens de déformation permettent avantageusement que la déformation subie par la partie de contact 120 soit sensiblement plus grande, en termes de distance horizontale, que celle subie par le reste de la partie active du joint d'étanchéité 100.Such deformation means thus make it possible to increase horizontally, by elastic deformation, the surface of the
Une telle configuration permet alors d'obtenir une excellente étanchéité au niveau d'une zone d'intersection entre un profilé de meneau et un profilé de traverse de la façade rideau, encore plus particulièrement dans un angle intérieur de cette zone au contact d'un élément vitré. En effet, en s'étirant de la sorte, le joint d'étanchéité 100 va être d'autant plus compressé face à un obstacle se situant dans sa direction d'étirement. Dès lors, on comprend que si cet obstacle est un autre joint d'étanchéité, la compression entre ces deux joints est fortement accentuée du fait desdits moyens de déformation.Such a configuration then makes it possible to obtain excellent sealing at the level of an intersection zone between a mullion section and a crosspiece section of the curtain wall, even more particularly in an interior corner of this zone in contact with a glazed element. Indeed, by stretching in this way, the
En outre, la déformation du joint d'étanchéité 100 permet aussi de compenser avantageusement les tolérances de fabrication de la façade rideau qu'il se destine à équiper, plus spécifiquement des tolérances dimensionnelles des profilés de meneau et de traverse. Cela est encore renforcé lorsque le joint d'étanchéité est fixé sur un profilé de meneau de sorte à être en contact avec un autre joint fixé sur un profilé de traverse. En effet, les mouvements relatifs de ces deux joints dus à la compression engendrée par les moyens de déformation permettent de minimiser les écarts possibles de montage qui pourraient résulter d'erreurs de fabrication, qui en générale peuvent être de l'ordre de quelques millimètres en ce qui concerne les profilés de la façade.In addition, the deformation of the
On note que cette capacité à compenser les tolérances de fabrication permet de la même manière de compenser les déformations que l'ossature de la façade est amenée à subir au cours de son cycle de vie, par exemple des déformations résultant de contraintes mécaniques et/ou thermiques fortes (exposition à des températures élevées, etc.). Là encore, la déformation du joint d'étanchéité 100, et surtout le fait qu'il est prévu d'être fixé en forte compression contre un autre joint, fait qu'il peut être soumis de manière additionnelle aux contraintes agissant sur la façade sans que l'excellente qualité d'étanchéité obtenue initialement ne soit mise en défaut au cours du temps.It should be noted that this ability to compensate for manufacturing tolerances makes it possible in the same way to compensate for the deformations that the framework of the facade is liable to undergo during its life cycle, for example deformations resulting from mechanical stresses and/or strong thermals (exposure to high temperatures, etc.). Here again, the deformation of the
Dans un mode particulier de réalisation, illustré par la
Il est à noter que la partie de contact 120 présente une telle surface bombée uniquement lorsque le joint d'étanchéité 100 est au repos. Ainsi, eu égard au fait que la partie de contact 120 est destinée à épouser la surface plane de l'élément vitré prévu pour prendre appui sur cette dernière, on comprend que la configuration de ladite partie de contact 120 vise non seulement un étirement horizontal mais aussi un aplanissement suivant la direction d'étirement. Un tel aplanissement favorise une meilleure étanchéité au niveau du contact avec l'élément vitré.It should be noted that the
En outre, ladite surface bombée est inclinée au moins au niveau de ladite première extrémité 121 d'un angle α non nul par rapport à l'horizontale, dans le sens allant du pied de fixation 110 vers la partie de contact 120. L'inclinaison d'une telle pente est adaptée à ce que la partie de contact 120 s'étire en priorité horizontalement, dans le sens allant de la face latérale d'appui 140 vers la face latérale de jonction 130. Par exemple, l'angle α est compris dans l'intervalle [15°, 35°] par rapport à l'horizontale (l'horizontale et l'inclinaison de la pente sont représentées en pointillés sur la
Dans un mode plus particulier de réalisation, ladite seconde extrémité 122 présente une forme de languette faisant saillie. Tel qu'illustré sur la
Rien n'exclut cependant d'avoir une configuration différente de la surface bombée de la parti de contact 120, dès lors que cette dernière permet en premier lieu d'étirer horizontalement la partie de contact 120 dans le sens allant de la face latérale d'appui 140 vers la face latérale de jonction 130. Par exemple, la surface bombée peut présenter une pente horizontale au niveau de la seconde extrémité 122 de sorte que la face latérale d'appui 140 est sensiblement perpendiculaire à la partie de contact 120 au niveau de ladite seconde extrémité 122.However, nothing excludes having a different configuration of the curved surface of the
Dans un mode préféré de réalisation illustré par la
Ainsi, lorsque le joint 100 est fixé sur un profilé de la façade rideau, la face latérale de jonction 130 penche vers l'extérieur, au-delà d'un cadre formant ledit profilé. Une telle configuration est particulièrement avantageuse lorsqu'elle est combinée aux moyens de déformation du joint d'étanchéité 100. En effet, l'inclinaison de la face latérale de jonction 130 permet, en elle-même, lorsque le joint 100 est fixé sur un profilé de meneau, de privilégier un contact de la partie supérieure dudit joint 100 avec un autre joint d'un profilé de traverse relié audit profilé de meneau. Le fait d'assurer ainsi un contact de manière prioritaire au niveau de la partie supérieure du joint d'étanchéité 100 contribue à sécuriser en tout premier lieu, du point de vue de l'étanchéité, un contact de joint à joint entre meneau et traverse, ce type de contact étant une zone connue comme étant critique du point de vue de l'étanchéité. Par ailleurs, on comprend aussi qu'en raison de la composition élastique du joint d'étanchéité 100, l'angle θ augmente lorsque le joint d'étanchéité 100 est compressé de la partie de contact 120 vers le pied de fixation 110. Cela permet de privilégier encore plus un contact au niveau supérieur du joint d'étanchéité 100.Thus, when the
Si les moyens de déformation contribuent à eux seuls à l'obtention d'une excellente étanchéité, on comprend que la combinaison des ces moyens avec une face latérale de jonction 130 inclinée selon l'invention contribue à l'obtention d'une étanchéité optimale. En effet, une fois un joint d'un profilé de meneau entré en contact avec une section transversale d'un joint de traverse, par l'intermédiaire de la face latérale de jonction 130 dudit joint de meneau, les moyens de déformation vont permettre, par pression de l'élément vitré sur les joints, que le joint du profilé de meneau s'étende vers le joint du profilé de traverse de sorte à augmenter la compression au niveau de leur contact. Le contact est alors scellé par cet accroissement du niveau de compression.If the deformation means alone contribute to obtaining excellent sealing, it is understood that the combination of these means with an inclined
On note que selon ce mode préféré de réalisation, et tel qu'illustré dans la
Rien n'exclut cependant, suivant d'autres exemples non détaillés ici, d'avoir d'autres valeurs pour l'angle θ. En particulier, rien n'exclut non plus que la face latérale de jonction 130 soit horizontale, c'est-à-dire que l'angle θ soit nul, auquel cas, seul les moyens de déformation du joint d'étanchéité 100 participent au rapprochement substantiel (et donc à la compression) du joint vers un autre joint de la façade.Nothing excludes however, according to other examples not detailed here, having other values for the angle θ. In particular, nothing excludes either that the
Dans un mode particulier de réalisation illustré par la
Dans un mode particulier de réalisation, le joint d'étanchéité 100 comporte des moyens d'aide à la découpe dudit joint d'étanchéité 100 selon un plan P horizontal positionné entre ladite partie de contact 120 et ledit pied de fixation 110. De tels moyens de découpe permettent avantageusement une découpe facile du joint d'étanchéité 100 dans ledit plan P de sorte à pouvoir ôter une masse dudit joint 100 (le plan P est représenté en pointillés dans la
Par exemple, lesdits moyens d'aide à la découpe sont au moins une alvéole 170 s'étendant, dans le plan P, sur une distance prédéterminée dans la longueur dudit joint d'étanchéité 100. Ainsi, en prenant la forme d'une alvéole 170, lesdits moyens d'aide à la découpe constituent un évidemment ciblé du joint d'étanchéité 100 au niveau du plan P, ce qui facilite la découpe du fait d'une diminution de la résistance rencontrée face à la masse élastique, et en permet ainsi une exécution nette et rapide dans une direction privilégiée. Dans l'exemple de la
L'invention concerne une façade rideau comportant des joints d'étanchéité. La
La façade rideau comporte une ossature formée par assemblage de profilés de meneaux 210 avec des profilés de traverses 220, ladite ossature supportant des éléments vitrés 300 de ladite façade rideau. Lesdits profilés 210, 220 sont classiquement réalisés par extrusion, par exemple à partir de matériau aluminium. En outre, selon un exemple préféré de réalisation illustré par la
Il convient de noter que l'ossature de la façade rideau est par exemple assemblée avant même d'être livrée sur chantier, ou par exemple encore livrée sur chantier en pièces détachées pour être assemblée sur place. Classiquement, la façade rideau ainsi constituée sépare l'environnement extérieur 10 d'un environnement intérieur 20 (bureaux, lieux de vie, etc.) destiné à accueillir des personnes.It should be noted that the framework of the curtain wall is for example assembled even before being delivered to the site, or for example still delivered to the site in separate parts to be assembled on site. Conventionally, the curtain facade thus formed separates the
La
Comme indiqué ci-avant, les profilés de meneau 210 et de traverse 220 mis en oeuvre pour former l'ossature de la
Il convient néanmoins de noter que cette manière de former l'ossature n'est en aucun cas limitative, les profilés de meneaux et de traverses pouvant différer à condition de respecter les autres caractéristiques énoncées ci-après.It should nevertheless be noted that this way of forming the framework is in no way limiting, the profiles of mullions and crosspieces may differ provided that the other characteristics set out below are respected.
Pour la suite de la description, la longueur d'un profilé 210, 220 correspond alors la dimension dudit profilé 210, 220 comptée selon l'axe normal à la section transversale telle qu'illustrée dans la
Chaque profilé 210, 220 comprend sur sa longueur au moins une rainure de fixation 230 ainsi qu'au moins une surface de drainage 240. Une telle configuration est connue de l'homme du métier.Each
Dans un mode particulier de réalisation, illustré par la
Dans un mode plus particulier de réalisation, le profilé 210, 220 comporte une rainure de maintien 250 configurée pour recevoir un élément de maintien, comme par exemple une vis 251, ledit élément de maintien 251 permettant de relier de manière fixe le profilé 210, 220 à un capot externe 400 de sorte que les éléments vitrés 300 sont maintenus entre ledit capot externe 400 et ledit profilé 210, 220. Par exemple, et tel qu'illustré par la
Chaque profilé 210, 220 est équipé d'au moins un joint d'étanchéité 100, de sorte que la partie de contact 120 d'un joint d'étanchéité 100 est déformée par compression exercée par un élément vitré 300. Comme explicité ci-avant, un joint d'étanchéité 100 est agencé de manière fixe dans une rainure de fixation 230 d'un profilé 210, 220 par insertion du pied de fixation 110 dudit joint d'étanchéité 100. Par exemple, et tel qu'illustré dans la
Rien n'exclut cependant, suivant d'autres non détaillés ici, que chaque profilé comporte deux joints d'étanchéité, un desdits deux joints d'étanchéité de configuration classique connue jusqu'à présent de l'homme du métier. On note cependant que la mise en oeuvre pour chaque profilé de deux joints d'étanchéité selon l'invention permet avantageusement d'obtenir une étanchéité optimale au niveau de chaque élément vitré.Nothing excludes however, according to others not detailed here, that each section includes two seals, one of said two seals of conventional configuration known up to now to those skilled in the art. It is however noted that the implementation for each profile of two seals according to the invention advantageously makes it possible to obtain optimum sealing at the level of each glazed element.
Les
Chaque profilé de traverse 220 est relié de manière sensiblement orthogonale à au moins un profilé de meneau 210 au moyen d'un connecteur 221 monté fixe au niveau d'une extrémité de liaison 222 dudit profilé de traverse 220, de sorte à prolonger ladite au moins une surface de drainage 240 dudit profilé de traverse 230, ladite extrémité de liaison 222 prenant alors appui contre ledit profilé de meneau 210. Un tel connecteur 221 est relié fixement à un profilé de traverse 220 de manière connue en soi, par exemple au moyen d'une vis. Un tel connecteur 220 est connu en soi, et par exemple conforme au connecteur décrit dans le document
Ainsi assemblée, ladite ossature forme un cadre de type grille. Chaque profilé de meneau 210 est alors relié à un ou bien deux profilés de traverse 220 selon que ledit profilé de meneau 210 est agencé en bordure ou non de ladite grille. On note par ailleurs qu'en complément de la mise en oeuvre de connecteurs 221, il est également possible d'utiliser, de manière connue en soi, des goupilles de maintien pour relier les profilés de meneau 210 et de traverse 220 entre eux.Thus assembled, said framework forms a frame of the grid type. Each
Tel qu'illustré sur la
Lesdits éléments vitrés 300 sont des panneaux de forme rectangulaire, chaque panneau formant par exemple un double vitrage. Une première vitre fait alors face à l'environnement extérieur 10, alors qu'une seconde vitre, séparée de la première vitre par une lame d'air, fait quant à elle face à l'environnement intérieur 20. L'assemblage d'un profilé de traverse 220 avec un profilé de meneau 210, côté intérieur, délimite des zones dites d'intersection 500 représentatives des espaces les plus vulnérables en termes d'étanchéité pour la façade rideau. De telles zones d'intersection 500 sont par exemple illustrées sur la
Par ailleurs, pour la configuration de la façade rideau, un joint d'étanchéité 100 d'un profilé de traverse 220 s'étend sur au moins toute la longueur dudit profilé de traverse 220, de sorte à être en contact exclusif avec un joint 100 de profilé de meneau 210. Par « contact exclusif », et tel qu'illustré dans la
Afin d'obtenir un tel contact exclusif, les joints d'étanchéité 100 de meneau 210 et de traverse 220 sont par exemple configurés de sorte qu'ils présentent des faces latérales de jonction 130 respectives de dimensions sensiblement identiques. Par exemple, en référence aux
On note par ailleurs que le fait que le joint d'étanchéité 100 d'un profilé de traverse 220 s'étend sur au moins toute la longueur du profilé de traverse 220 permet audit joint 100 d'avoir une section transversale qui, a minima, affleure avec une extrémité de liaison 222 dudit profilé de traverse 220. Une telle configuration permet d'engager le contact avec le joint d'étanchéité 100 situé en regard sur le profilé de meneau 210 relié audit profilé de traverse 220. Dans la mesure où la partie de contact 120 du joint de meneau 210 est étirée en raison de l'appui réalisé par l'élément vitré 300, on comprend que les deux joints 100 entrent en contact en se compressant mutuellement au niveau de la zone d'intersection 500. Une telle compression est par ailleurs accentuée lorsqu'au moins la face latérale de jonction 130 du joint 100 du profilé de meneau 210 est inclinée d'un angle θ non nul, comme expliqué ci-avant en détails.It is also noted that the fact that the
Dans un mode particulier de réalisation, un joint d'étanchéité 100 d'un profilé de traverse 220 s'étend sur une distance sensiblement supérieure à la longueur du profilé de traverse 220. Par exemple, la différence de longueur entre le joint d'étanchéité 100 et le profilé de traverse 220 est de l'ordre de quelques centimètres, par exemple une différence comprise dans l'intervalle [1cm, 3cm], par exemple plus particulièrement 2cm. Une telle configuration permet au joint 100 du profilé de traverse 220 de se prolonger légèrement au-delà de l'extrémité de fixation 222 dudit profilé de traverse 220, de sorte à rapprocher encore plus l'extrémité du joint 100 de traverse de la partie de contact 120 du joint de meneau. Ainsi, la compression mutuelle obtenue entre joint de traverse et joint de meneau est encore avantageusement renforcée.In a particular embodiment, a
De plus, chaque joint d'étanchéité 100 d'un profilé de meneau 210 comporte une encoche 160 configurée pour coopérer, en compression le long dudit joint d'étanchéité 100, avec le connecteur 221 reliant ledit profilé de meneau 210 à un profilé de traverse 220. Une telle encoche 160 forme donc un évidemment dans lequel le connecteur 221 vient se loger de sorte à être en contact avec toute la surface de ladite encoche 160. Il importe de noter que par « encoche », on fait référence ici à une partie évidée qui ne traverse pas entièrement le joint 100. Autrement dit, le joint de meneau comportant une telle encoche 160 reste d'un seul tenant.In addition, each
Par exemple, et tel qu'illustré dans les
En outre, le fait que l'encoche 160 est configurée pour coopérer avec le connecteur 221 en compression le long dudit joint d'étanchéité 100 permet également d'obtenir une excellente étanchéité au niveau des contacts établis entre le connecteur 221 et la surface de l'encoche 160 qui n'est pas parallèle à l'axe longitudinal du joint d'étanchéité 100. Par exemple, et tel qu'illustré dans la
Dans un mode préféré de réalisation, illustré par la
On note qu'une telle configuration du rebord 241 de la surface de drainage 240 permet avantageusement la coopération d'éléments de quincaillerie qui sont ainsi maintenus fixes avec le profilé 210, 220 au niveau de la surface de drainage 240. Par exemple, lesdits éléments de quincaillerie sont des plaques de soutien du vitrage, fixées aux profilés de traverse 220 et sensiblement normales aux surfaces de drainage 240 de ces profilés.It is noted that such a configuration of the
La description ci-avant illustre clairement que par ses différentes caractéristiques et leurs avantages, la présente invention atteint les objectifs qu'elle s'était fixés. En particulier, une façade rideau équipée de joints selon l'invention présente des performances d'étanchéité optimales et pérennes, lesdits joints permettant également de compenser efficacement, au cours du temps, les tolérances de fabrication de ladite façade rideau, ainsi que les déformations subies.The above description clearly illustrates that through its various characteristics and their advantages, the present invention achieves the objectives that it had set itself. In particular, a curtain facade fitted with seals according to the invention has optimum and long-lasting sealing performance, said seals also making it possible to effectively compensate, during the time, the manufacturing tolerances of said curtain wall, as well as the deformations undergone.
