Sealing device of a carpentry assembly Field of application of the invention

[0001] The present invention is related to the field of carpentry assemblies and particularly to the adaptations that make it possible to optimize the tightness in the assembly of two profile ends whose longitudinal axes are likely not to be parallel.

Description of the prior art state

[0002] In the domain of curtain walls, frames consisting of factory pre-assembled profiles are used. To form completely or partially glazed facades, these frames are juxtaposed and joined together.

In order to realize the air and water tightness of these assemblies, joints are used to fill the connection spaces that separate said frames and are particularly susceptible to rain or condensation water filtration.

[0003] The creation of the sealing of such assemblies is sometimes with a complementary difficulty because the facades formed have faces that then define different spaces and separations for the joints that participate in the sealing.

[0004] US-3994107 shows a facade and its joints.

However, existing joints that have surfaces that fit and cover the surfaces of the ends of the profiles to be connected cannot adapt to the angle adopted by these two profiles without this detrimental to the tightness when deviating or stretching inconsiderately.

[0005] Until now, the solution has been to create a special meeting dedicated to each angle defined by the frames and the profiles that constitute them.

Such a solution makes the realization of a curtain wall with faces particularly expensive and constitutes an obstacle to further diffusion of the curtain walls.

Another solution is proposed by document WO-A-2004/063517.

[0006] Another drawback concerns the variations in the separation between the profiles that are likely to occur due to the phenomenon of dilatation.

Description of the invention

[0007] In verifying this, the applicant has carried out investigations that have led to a sealing system of a carpentry assembly that solves the problems found in the assemblies of the constituent frames of the curtain walls with faces.

[0008] According to the invention, the curtain wall system comprising a sealing device and at least two preassembled frames constituting the curtain walls, which performs the air and water tightness of these assemblies when filling the connection spaces that separate said frames, it is notable for the fact that it is disposed between the ends of two profiles of two adjacent frames and comprises at least one seal that is preformed to fit the shape of said ends and partially covers them to constitute at least one continuous surface, where the profiles are identical, said joint is preformed in its middle zone so that it forms folds arranged in divergent radii around a center disposed near the middle of the connection area between the two profiles, folds that allow the deployment and folding of the joint whatever the deformation and / or angular positioning followed by said profiles.

[0009] This feature is particularly advantageous because, thanks to this fan preform, the joint can, in the area that separates the two ends and in the plane of the coated surfaces, deform without creating slits or stretches susceptible to damage it and prevent it from performing its function.

Thus, a single joint can, by limiting its length to the area of the ends and at the limits that define its folds, ensure the function of tightness between two profiles whose separation between the two ends must be tight and capable of varying according to the phenomena of dilatation suffered or according to the angle adopted.

[0010] This device can, therefore, ensure the tightness between the ends of two cross-members of two glazed frames that form a face of a curtain wall to adapt to the angle formed by the two frames.

In addition, such a device can ensure the same function without modification when the profiles whose separation must be sealed are arranged in the extension of the other.

The preformed area to form folds can then assume the variations due to dilation.

It should be understood that, within the framework defined by a curtain wall use with a configuration of elements

Pre-assembled units, the realization of the continuity of the seal between two cross-members of two different frames arranged in an adjacent manner also ensures the function of sealing with the cross-members of the elements arranged above and that are assembled on the cross-members of the lower elements.

In this way, this device ensures the tightness between four crossbars.

[0011] In such a configuration, the identical crossbars from one frame to the other have horizontal surfaces that are likely to be present in the same horizontal plane from one frame to the other but with non-parallel longitudinal axes.

The joint of the invention will connect these surfaces and make the splice in said horizontal plane due to its deformability thanks to its fan.

[0012] According to a preferred feature, the folds are formed by an accordion preform.

[0013] According to another characteristic, the folds are formed by a succession of grooves and ribs installed in the joint.

[0014] In order to optimize the deformation of the joint in spite of the angle of the assembly to be sealed and in order that a part of the joint does not constitute an obstacle to the deformation of the part carrying the folds, said joint is preformed with two perpendicular surfaces to ensure the continuity of two practically perpendicular surfaces of said profiles.

This feature allows to adapt to the sealing of profiles that have, for example, horizontal and vertical surfaces.

[0015] In order that the angle formed by the profiles can be applied to the joint so that it is deformed as coherently as possible, said surfaces to be connected from the ends of the profiles are preformed with holes in which they are introduced. the corresponding profile projections coming out of the lower face of the covering parts of said joint arranged to both parts of the folded part.

In this way, the profiles that receive said joints also participate in the invention.

[0016] According to another particularly advantageous feature of the invention, the central part of said joint is occupied by a concave preform forming an axis gutter practically perpendicular to the longitudinal axis of the profiles connected by said joint.

This gutter advantageously directs out the waters flowing over the joint.

Thus, said joint not only ensures water tightness at the junction of two curtain wall frames, but also performs the evacuation of said waters.

[0017] In order to optimize this evacuation, this gutter formed in the joint disposed within the traverse profiles is extended by a projection projecting outward beyond the outer flange of the joint, that is, beyond the plane formed by the frames in the vertical space between the flanges of said frames.

[0018] According to a preferred embodiment, said projection decomposes into a vertical gutter whose upper end extends the first gutter mentioned above and whose lower end joins a new practically horizontal projection ensuring maximum separation of the water flow point. with respect to the glazed surface.

[0019] According to another particularly advantageous feature of the invention, said gasket is equipped with a flat rectangular part that projects downwards from the lower surface of said gasket and partially occupies a vertical plane arranged immediately below the crossbars.

[0020] The association between the profiles and the joint is also completed, according to a preferred embodiment, by gluing.

According to another embodiment, the maintenance in position is ensured through screws.

[0021] According to another particularly advantageous feature, the surfaces of the ends of the profiles are preformed, in one of their flanges, with a groove groove of a complementary linear joint whose corresponding joint surface, that is, the flange of the joint which ensures the continuity of said corresponding profile surface flange, is also preformed to ensure continuity between the two profiles.

[0022] According to another particularly advantageous feature, the flange of the surfaces of the profiles, preformed with a groove of engagement, is also preformed with an attached groove that welcomes the corresponding flange of the joint surface disposed to both parts of the part of flange that ensures the continuity of said groove to obtain an optimized arrangement.

[0023] According to another particularly advantageous feature, said joint is made of various materials.

In fact, certain joint parts require flexibility (pleated area) while other parts require a large

The flexible material may be known by the generic name of EPDM.

[0024] In addition, to ensure the tightness of a more complex profile, such as that of a curtain wall frame traverse, said joint can be completed by other joints that fill the gap between the two ends and that are preformed with a pleated area. / ribbed to accept deformation.

[0025] The sealing device is completed by another gasket arranged at the rear of the crossbar towards the interior of the building and which ensures the same functions as the first gasket at the rear of the crossbar.

This complementary joint adopts the same characteristics as regards, in particular, the folds that the joint defines above but without the projection outwards.

[0026] The fundamental concepts of the invention that have just been set forth above in their most elementary form, other details and features will be seen more clearly with the reading of the description that follows and when observing the attached drawings, which provide an example mode not limiting a form of realization of a system according to the invention.

Description of the modes of realization

[0028] The sealing device of the invention ensures the water tightness of the curtain walls as illustrated by the drawing in Figure 1.

This curtain wall M is composed of a plurality of frame elements C associated with each other to form rows and columns.

An example of frame element C is illustrated in the drawing of Figure 2.

This frame element C is formed by a frame 100 formed by two uprights 110 and 120 and by two crossbars 130 and 140 that frame a glass window 200.

[0029] According to the needs to which the device of the invention responds, the curtain wall M is capable of presenting faces formed by vertical connections between the frame elements C of the same column that presents an angle between the frame elements C of the adjacent column.

The sealing device of the invention ensures the at least water tightness of the connections between the different frame elements C by associating with the ends of their crossbars 130 and 140 at the level of the connection areas.

[0030] Thus, as illustrated in the drawings of Figures 3 and 4, the joints constituting the device of the invention rest on the ends of the upper crosspieces 140 and 140 'of two frame elements C and C' arranged next to each other and fixed to each other.

These joints are also in contact with the lower part of the frame elements arranged above.

The crosspieces 140 and 140 'are identical from one frame C to the other C' and have horizontal surfaces that are likely to be present in the same horizontal plane from one frame to the other but with non-parallel longitudinal axes.

The seals of the invention adopt a symmetrical configuration and will connect at least these surfaces to ensure water tightness by being preformed to fit the shape of said ends and partially cover them to constitute a surface continuity.

[0031] The sealing device will thus fill the connection spaces that separate said frames. As illustrated in the drawing in figure 3, once all four elements are installed, only the device of the invention appears, when projecting the joint part outwards to carry out the evacuation of the waters flowing over the crossings towards the Exterior.

[0032] This sealing device decomposes into a joint 300 that is arranged in the front of the crossbars and a complementary joint 400 arranged in the rear.

[0033] As illustrated in the drawings of Figures 5a, 5b, 5c and 5d, said seal 300 arranged in the front part, that is, in a part of the crossbar located on the outer side, is preformed in its area means for forming folds 310 arranged in divergent radii around a center disposed near the middle of the connection zone between the two profiles, folds that allow the deployment and folding of the joint according to the deformation or angular positioning followed by said profiles in the connection between framework elements in which they participate.

[0034] According to the preferred embodiment illustrated, the folds 310 form two fans 311 and 312, one for each connected crossbar, which starts at each crossbar.

It is understood that, being fixed at the ends of the crossbars that face the frame elements C and C adjacently arranged in a curtain wall, the joint will be able to guarantee its sealing function regardless of the orientation of the cross each other.

[0035] In order to optimize the deformation of the joint in spite of the angle of the assembly to be sealed and in order that a part of the joint does not constitute an obstacle for the deformation of the part carrying the folds, said joint 300 it is preformed with a surface practically perpendicular 320 to the horizontal plane defined by fans 311 and 122 to ensure the continuity of two corresponding practically perpendicular surfaces of said profiles 140 and 140 'of the crossbars.

[0036] In order that the angle eventually formed by the cross members can be applied to the joint 300 so that it is deformed in the most consistent manner possible, said surfaces to be connected from the ends of the profiles are preformed with holes in which the corresponding profile projections 330 are introduced from the underside of the covering parts of said joint 300 arranged to both parts of the folding part formed by fans 311 and 312.

[0037] As illustrated, the central part of said joint 300, that is to say the part located on both sides of the symmetry plane and between the two fans 311 and 312, is occupied by a concave preform forming the shaft gutter 340 practically perpendicular to the longitudinal axis of crosspieces 140 and 140 'connected by said joint.

This gutter 340 advantageously directs outward the waters flowing over the joint (presence of an inclination?).

[0038] This horizontal gutter 340 formed in the joint disposed inside the traverse profiles is extended by a projection 341 projecting outwardly beyond the outer flange of the joint and the plane formed by the frames in the vertical space existing between the flanges of said frames.

[0039] According to a preferred embodiment, said projection 341 decomposes into a vertical gutter 342 whose upper end extends the above-mentioned horizontal gutter 340 and whose lower end is attached to a new horizontal projection 343 inclined downward.

[0040] As illustrated, this joint 300 is also equipped with a flat rectangular part 350 that projects downwardly from the lower surface of said joint 300 according to a vertical plane practically parallel to the longitudinal axis of the crossbars and which It occupies at least partially a vertical plane arranged immediately below the crossbars to complete the different sealing solutions made in this area.

[0041] The association between the profiles and the joint is also completed, according to a preferred embodiment, by gluing.

According to another embodiment, the maintenance in position is ensured through screws 500 that cooperate with the protruding shapes down 330.

[0042] As illustrated, the surfaces of the ends of the crosspieces are preformed on one of their flanges by a groove groove of a complementary linear joint whose corresponding joint surface 321, that is, the flange of the surface 320 of the joint 300 that ensures the continuity of said corresponding profile surface flange, is also preformed to ensure continuity between the two crossbar profiles.

[0043] According to another particularly advantageous feature, the flange of the surfaces of the preformed profiles with a groove of groove is also preformed with an attached groove that welcomes the corresponding flange 322 of the joint surface disposed to both parts of the flange part 321 which ensures the continuity of said groove to obtain an optimized arrangement and a better fixation of the joint to the crossbar profile.

[0044] According to another particularly advantageous feature, said joint is made of various materials.

In fact, certain joint parts require flexibility (pleated area), while other parts require great rigidity (projections that are introduced into the grooves made in the profiles).

The flexible material may be known by the generic name of EPDM.

[0045] As explained above, the sealing device is completed by another gasket 400 arranged at the rear of the crossbar towards the interior of the building and which ensures the same functions of the first gasket at the rear of the crossbar.

[0046] As illustrated in the drawings of Figures 6a, 6b, 6c and 6d, this complementary joint 400 covering the rear part of the ends of the crosspieces 140 and 140 'adopts the same characteristics as regards particularly the folds that the joint 300 described above, but without the projection outward 341.

The manufacture of such a joint 400 thus again adopts the characteristics of the preceding one.

[0047] As for the preceding joint 300, the joint 400 adopts a symmetrical configuration having a central gutter 440 horizontally on both sides of which a preformed part with folds 411 and 412 is fan-deployed.

These fan portions rest at least partially on the horizontal surface of the backs of the crossbars.

This joint 400 also ensures the continuity of the vertical part of the rear parts of the profiles by means of a corresponding perpendicular part 420.

[0048] This vertical part 420 ensures the continuity of the preformed grooves in the flanges of the profiles.

Thus, a projection 421 exiting the vertical flange 420 of the complementary joint 400 is preformed to ensure continuity of the groove for fixing a linear joint.

Similarly, to both parts of this projection, the upper parts of the flanges 422 of the joint 420 are preformed to cooperate with a corresponding groove preformed in the profile.

[0049] As illustrated, this joint 400 is also equipped with a flat rectangular part 450 projecting downward from the bottom surface of said joint 400 according to a vertical plane practically parallel to the longitudinal axis of the crossbars and occupying the less partially a vertical plane arranged immediately below the crossbars to complete the different sealing solutions made in this area.

[0050] The projections 430 downwards, from the underside of this joint 400, ensure the connection with the preformed crossbars correspondingly in association with a bonding and / or screwing.

[0051] It is understood that the system, which has just been described and represented, has been in view of a disclosure rather than a limitation.

Of course, various conditioning, modifications and improvements may be contributed to the previous example, without leaving the field of the invention.
