Abstract

This system, of the "grid" type, uses a basic structure made up of posts (8) and horizontal cross members, of I-section, assembled together. The invention relates to the adaptation of such a system to frames or frames of the "VEP" (parclosé exterior glazing) and "VEC" (glued exterior glazing), fixed or opening, with slots (6) between filling elements. adjacent (2). For this purpose, frames are provided formed using specific profiles (19), the section of which results from a tubular part (20) and from several wings (21, 22, 23, 27). Two wings (21, 22) are provided for retaining the frame on the posts (8) and cross members. Another wing (23) is extended outwards by a part (26) provided for fixing a filling element (2), such as glazing, for example by means of a glazing bead (28). The adaptation to various application cases is done by simple edging of the profiles (19).

Description

The present invention relates to a curtain wall system

standardized, like "grid".

  More particularly, this invention aims to improve, in a significant way, a curtain facade system known under the trade name "PANOVAR", which comprises a grid composed of posts and horizontal crosspieces, assembled together only by clipping, without the use of screws , and receiving filling elements put in place by a mounting technique called

  lateral sliding or in "portfolio".

  Such a curtain wall system therefore does not have any binding mechanical connection, between horizontal crosspieces and uprights, and it is thus designed to avoid disorders due to mechanical stresses transmitted by all conventional systems of the "grid" type,

rigid to the assemblies.

  As regards the filling elements, which can be single or double glazing, opaque panels, opening frames, etc., the mounting technique consists in sliding the filling element at an angle in the largest rebate vertical of a post, then put the said element in an upright position and also introduce it, on the opposite side, in the smallest rebate of the next post (knowing that each post is formed by an "I" profile, but asymmetrical so as to have a larger rebate on one side and a smaller rebate on the other side). This operation being completed, the filling element is lifted so as to be trapped in the upper rebate, and wedged in the lower rebate. A low external glazing bead can then be laid, and thus close the rebate on the four external sides of the filling element, this in a manner in accordance with regulatory requirements. This rebate is said to be drained, with drainage not visible, and with pressure equilibrium (with the outside): the water cannot go up in the rebate, and it is evacuated outside by holes located

  behind the vertical face of the glazing bead.

  Such a curtain facade system thus has qualities of ease and speed of assembly, and sealing, and it proves to be very competitive.

on the economic plan.

  However, for this curtain facade system of the "grid" type, there is currently no known possibility of mounting frames of the so-called "V.E.P." types. (glazed exterior glazing) and "V.E.C." (glued exterior glazing), which have the particularity of having a slot with a width of the order of 20 to 30 mm) between two neighboring edges of adjacent frames, and which are currently very popular in architectural terms. There is even a prejudice in the profession, according to which a curtain wall with "V.E.P." type frames or "V.E. C." would be impractical, on

  the basis of a grid system as previously mentioned.

  The present invention therefore aims to provide a curtain wall system for the adaptation of these frames type "V.E.P." or "V.E.C.", or the like, on a grid of the kind considered here, by proposing

  a light, economical solution that guarantees quality sealing.

  To this end, the subject of the invention is a standardized curtain wall system, of the "grid" type, using a basic structure consisting of posts and horizontal crosspieces, of "I" section, assembled together in particular by clipping, and receiving glazed or opaque filling elements, this system being characterized in that, for its adaptation to frames or chassis of the "VEP" types and "VEC", fixed or opening, with slots between adjacent filling elements, frames are provided made up of profiles, each profile having an initial section resulting from: - a tubular part of elongated section, -from three wings extending from the tubular part, on the same longitudinal side of the latter, respectively at the rear, at an intermediate point of the length, and at the front of said tubular part, so as to define two parallel grooves, and - of a part extending the front wing towards the outside, the rear wing and the intermediate wing being provided for retaining the frame on the posts and cross-members of "I" section the basic structure, with interposition of seals, the frame being notably introduced by lateral sliding, while the part, extending the front wing towards the outside, is provided for the fixing of an element

  filling, such as glazing, on the frame.

  The invention thus provides a system based on the use of a universal profile which still allows easy mounting of the frames (formed using this profile) by lateral sliding, and which can be

  used for different purposes, in particular for "V.E.P." type frames

  or "V.E.C.", this without modification or deletion of certain

parts by simple trimming.

  In particular, in the case of "VEP" type frames, profiles are used having the previously defined complete initial section, the part of each profile extending its front wing in the direction of o10 the exterior still receiving an external glazing bead, assembled by

clipping on said part.

  In the case of "VEC" type frames, the part of each profile extending its front wing in the direction of the outside is advantageously shortened by an edging, and it receives a support profile, on which is glued by its inner face the element of

filling, in particular glazing.

  In one embodiment of the invention, each section also has a short oblique wing, extending from the front end of the tubular part and directed towards the part extending its front wing and directed towards the outside. In the case of a "V.E.P." type frame, the oblique wing carries a peripheral seal applied to the interior face of the filling element, in particular glazing. In the case of a "VEC" type frame, this oblique wing is used, together with the part extending the front wing in the direction of the outside, for the sliding introduction of the support profile on which the element of

filling, in particular glazing.

  In the case of opening frames, the previously defined profile can also be used to form part of the opening, by shortening its rear wing and its intermediate wing by trimming, so as to leave room for a profile constituting the frame, the latter being

  inserted in a post or a cross member of the basic structure.

  Thus, from a single profile, it is possible to decline several achievements, which all retain qualities of lightness, tightness and economy. In particular, the "V.E.P." systems and "V. E.C." currently on the market are expensive, because the grids placed behind "V.E.P." type frames or "V.E.C." must, to have the required inertia, be made with large and heavy tubular profiles. The system proposed by the present invention is lighter, because its "I" profiles (posts and crosspieces) have metal masses distant from each other, which provide equivalent inertia for a lower mass. In addition, these profiles being, in the case of the invention, open and no longer tubular, these are less expensive. Furthermore, insofar as the invention uses a single profile for the frames, making it possible to respond to all cases by simple trimming, here an additional saving is obtained in comparison with the conventional systems, which require a whole range of profiles, to be manufactured in different sectors from each other, and leading to large stocks since each type of profile must

be available.

  The invention will in any case be better understood using the

  description which follows, with reference to the attached schematic drawing

  representing, by way of example, some embodiments of this standardized curtain wall system: FIG. 1 is a front view of a portion of curtain wall type "V.E.P", in accordance with the present invention; Figure 2 is a partial view in horizontal section and on an enlarged scale, along 11-It of Figure 1, of this curtain facade of type "V.E.P."; Figure 3 is a partial view in vertical section and on an enlarged scale, along 111-111 of Figure 1, of said curtain facade type

"V.E.P";

  Figure 4 is a view in horizontal section and on an enlarged scale, along IV-IV of Figure 1, of the same curtain facade, illustrating the application of the invention to opening frames Figure 5 is a view in horizontal section, similar to Figure 2 but illustrating the application of the invention to a curtain type facade

"V.E.C.";

  Figure 6 is a vertical sectional view, similar to Figure 3 but relating to a facade type "V.E.C."; Figure 7 represents the section of the specific profile of the facade

  curtain object of the invention, with indication of the trimming axes.

  FIG. 1 shows a portion of a curtain facade, of the "grid" type, which includes filling elements of various types, in particular: glazed fixed frames 2, glazed fixed sills 3, opaque sills 4 in particular in the form of sandwich panel, glazed opening frames 5, etc. These various filling elements 2 to 5 are not contiguous, but remain separated by slots 6 and 7, respectively vertical and horizontal, the width of which is between 20 and 30 mm . Referring to Figures 2 and following, the basic structure of the curtain wall consists of posts 8 and horizontal crosspieces 9, in correspondence with the vertical and horizontal lines of the grid, the posts 8 being themselves fixed to the main work of a building (in a known manner, not shown). The posts 8 are constituted by reconstituted "I" profiles, in which there is a core 10 and two wings 11 and 12, respectively interior and exterior (by reference to the building in front of which the curtain wall is placed). These posts 8 thus comprise two opposite rebates 13 and 14. Each post 8 is asymmetrical, in the sense that its core 10 is offset laterally relative to its median plane 15; thus, the post 8 has a large rebate 13, and a smaller rebate 14. The horizontal crosspieces 9 also have an "I" section, but they are perfectly symmetrical and result, each, from the assembly of three sections, either a main section 16 in "Z" and two complementary sections in "L" 17 and 18, called glazing beads. The ends of the crosspieces 9, thus formed, are clipped onto the posts 8, provided with

this effect of appropriate notches.

  Referring more particularly to FIGS. 2 and 3, the adaptation of glazed fixed frames 2, for example with double glazing, will now be described on the basic structure previously described. This adaptation is done through frames, formed using

  specific profiles 19 (see also figure 7).

  The section of a profile 19 can be defined as follows - The base of the profile 19 is a tubular part 20, of section

very elongated rectangular.

  -Three wings 21, 22 and 23 extend from the tubular part 20, on the same longitudinal side thereof respectively at the rear, mid-length and at the front of this part 20, defining with it a "double U" (double

groove 24, 25).

  - The front wing 23 is extended by a part 26, overall

  perpendicular to this wing 23, and directed towards the outside.

  - At the front of the tubular part 20, the profile 19 also has a short oblique wing 27, directed towards the part 26 previously defined. More particularly, FIGS. 2 and 3 showing the adaptation of a chassis of the "VEP." Type (glazed exterior glazing) on the basic structure, the fixed glazed chassis 2 are held on the frames formed using profiles 19, by means of external glazing beads 28, of "L" profile, assembled by clipping on the parts 26 (directed towards the outside)

profiles 19.

  The frames, made up of profiles 19, are assembled in the workshop, and fitted with glazed frames 2. They are thus delivered to the

  site, ready to be mounted on the basic structure.

  The shape resulting from the two wings 21 and 22 of the sections 19 (first peripheral groove 24) allows the introduction of the frame in a vertical position, by lateral sliding, external peripheral joints 29 already being in place on the external wings 12 of the posts 8, as well as on the crosspieces 9, and applying to the intermediate wings 22 of the profiles 19. Inner peripheral joints 30 are put in place at the end of the frame mounting operation, between the inner wings 11 of the

  posts 8 and rear wings 21 of profiles 19.

  The shape resulting from the two wings 22 and 23 of the sections 19 (second peripheral groove 25) allows the recovery of water,

  resulting from possible infiltration, which cannot migrate inward.

  This shape is also adapted to allow the introduction of frames

between the posts 8.

  The tubular part 20 of the profiles 19 allows their assembly

  angle, in the workshop, by means of brackets, to constitute frames.

  In addition to the fixing of the external glazing beads 28, the parts 26 (directed towards the outside) of the sections 19 are used for fixing finishing joints 31, in the form of lips, which overlap two by two.

  and thus close the slots 6 and 7, behind the glazing beads 28.

  Figures 2 and 3 also show - peripheral seals 32 held by the oblique wings 27 of the sections 19, and applied to the inner face of the glass frames 2; - Peripheral seals 33 held by the external glazing beads 28, and applied to the external face of the glazed frames 2; - Lower wedging elements 34 of the frames, housed in the upper rebate of the crosspieces 9; - angle wedging elements 35 of the same frames, housed

  in the lower rebate of the crosspieces 9.

  FIG. 4 illustrates the application of the same system to glazed opening frames 5. The profiles 19 are here delineated along an axis 36, by shortening the two wings 21 and 22 (see also FIG. 7), but are not modified by the remain, and are part of the "opening". The "frames" are made up of standard profiles 37, inserted between the wings 11 and 12 of the posts 8 with interposition of seals 29 and 30, and also inserted from

  similarly in the sleepers 9.

  Figures 5 and 6 show the chassis adaptation of the "V.E.C." type (glued exterior glazing) on the same basic structure, consisting of posts 8 and crosspieces 9. In this other application of the invention, glazing 2 (here: double glazing) is no longer held by exterior glazing beads, but is glued, by their inner face, on

support profiles 38.

  The assembly always uses frames, formed using the same profiles 19 here delineated along an axis 39 (see also Figure 7). Thus, the part 26 of the profiles 19 is shortened, and is interrupted substantially opposite the end of the oblique wing 27. Each support profile 38 is introduced by sliding (before assembly of the frame) between what remains of the part 26, on the one hand, and the end of the oblique wing 27, on the other hand. The mounting of the frames on the basic structure is not modified, and the exterior 29, interior 30 and finishing 31 seals are retained, as are the peripheral seals 32 applied to the interior face of the panes (the latter seals 32 being carried over however

on the support profiles 38).

  Thus, the same profile 19, possibly delimited, allows the fixing of fixed frames of the "V.E.P." type. or "V.E.C.", as well as the mounting of opening frames, not only of type "V.E.P." (as illustrated in figure 4) but also of type "V.E.C.", this in a way not illustrated

but easily conceivable.

  As is obvious, and as appears from the foregoing, the invention is not limited to the sole embodiments of this standardized curtain wall system which have been described above, by way of examples; on the contrary, it embraces all of the variant embodiments and applications respecting the same principle. In particular, starting from the various embodiments described and illustrated in the drawing, it is conceivable to create, still by simple trimming, an interruption of the profile 19, producing a thermal break, this interruption being located in particular between the front wing 23 and the part 26 (directed to

  outside) which extends this wing 23.
