Description

Clamping device for juxtaposed panels that form a vertical curtain wall for a real estate facade or Similary.

The present invention relates to a device for fastening elements or panels, glass or not, that form the facade of a similar building or building, constituting what in the art it is appropriate to call "curtain wall", being appropriate this device to ensure support and tightness of these elements in conditions of effectiveness satisfactory, limiting the number of pieces required.

The curtain wall facades of real estate or Similar generally include a support armor mounted on right angle with the exposed part of the facade, being constituted this armor by a mounting of vertical uprights continuous over the entire height of the wall and by crossbars horizontal that intersect at the point of their union with these uprights and that delimit with these last alveoli of form general rectangular, in each of which a appropriate element or panel, glass or not, forming the set of these panels the corresponding exterior wall of the facade.

The uprights and crossbars form jointly, in each of the cells that houses a panel, a open renvalso on whose bottom the periphery of this panel is supported applied against a seal. Then the panel it is held in position, and particularly held tightly against the joint carried by the uprights and crossbars, with help of a plurality of support bodies, called "fasteners", which extend parallel to these uprights and crossbars over the entire height and width thereof, including these fasteners other joints on its directed surface towards the panel, which in turn are applied on the panel surface on the opposite side to the one pressed against the first joint in the reimbursement fund.

The panel thus captured between the armor of support formed by the uprights and crossbars and fasteners, those against the latter being immobilized through locking screws that cooperate particularly with an extension radial planned on each upright and crossbar, in the region that separate two consecutive panels on the facade.

Then a cover of finish on fixed vertical and horizontal fasteners against the uprights and crossbars, to frame the panels and form on the peripheral sides thereof, outwards of the facade, a narrow frame, which covers the edges of these panels in the curtain wall assembly.

This classical structure, described for example in US-A-3 734 550, It has the disadvantage that it requires significant amounts of materials and numerous pieces, which really go beyond what it is justly necessary, both to effectively guarantee the support and fastening of the elements and panels, glass or not, which constitute the curtain wall, as well as its tightness.

The object of the invention is a device simplified that avoids this inconvenience.

For this, the device considered, for the clamping juxtaposed panels, glass or not, of a wall vertical curtain for a building or similar facade, by means of a support frame that includes vertical uprights continuous and horizontal crossbars between these uprights vertical, to delimit with the same reception alveoli for each of these panels applied to the bottom of a rebate open arranged in the socket that receives this panel against a sealing gasket mounted on the bottom of the renvalso and covered by these uprights and crossbars, with this joint resting on the peripheral edge of the panel, resting it on its bottom in the renewal by means of placement chocks or the like, carried by the crossbars, by means of support pieces, each notch presenting a notch, this being characterized device because it includes, fixed on horizontal crossbars exclusively, a sealing profile in Z that extends according to the length of the crossbars, this profile being, on the one hand, solidarity in the notch of each crossbar by one of the wings of the Z and that, on the other hand, it will cover the panel located below the crossbar following the top edge of this panel, and at least one clamping body that rests on the upper edge of the panel covered by the Z profile and also on the lower edge of the panel located above, this fastener being fixed to the crossbar arranged between the two panels.

Thanks to these provisions, each panel of glass is thus supported following its lower edge in the open renewal of the receiving alveolus, by means of chocks placement resting on the crossbar while this panel it is held simultaneously following its upper edge and its edge bottom by means of unique clamping pieces, distributed by the length of the crossbars located above and below this panel, realizing the tightness of the assembly, by the top of the panel, by means of the Z profile covering the upper edge of this panel.

If necessary, the device includes also, fixed on the vertical uprights of the reinforcement of support, supplementary restraints that rest on the side edges of the panels, which will complete the effect of the first fasteners applied on the upper edges and bottom of each panel, to perfect the subjection of the same in Your socket

According to another characteristic, the organs of fastening that hold each panel, include on its surface opposite an elastic coating thereof to prevent deterioration of the panel.

Also, according to another characteristic, the organs clamping include on its opposite surface to which it rests on the panels, hooking means that allow fixing there by the exterior, preferably as a clip, a decorative cover, which it extends advantageously over all or part of the length of the horizontal crossbars or vertical uprights of the armor.

In a preferred embodiment, each crossbar includes an outward median extension outward, on which the profile of Z-tightness of the panel covering underneath and panel fasteners located above and below the crossbar.

Other features of a device protection and fastening of elements or panels, of glass or not, of a curtain wall for a building facade, established according to the invention, will appear even through the description that follows of an exemplary embodiment, given as an indication and not limiting, with reference to the accompanying drawings in which:

- Figure 1 is a very schematic view of a section of a curtain wall for a building facade, which illustrates the panel support armor, glass or not, housed in This facade.

- Figure 2 is a cross-sectional view part of a device for fixing and fastening the panels of a curtain wall, according to the prior art.

- Figure 3 is a perspective view of the device according to the invention for fastening in the armor of glass panel support.

- Figures 4 and 5 are seen in sections horizontal and vertical, respectively, of the device of the figure 3.

In figure 1, reference 1 indicates very curtain a curtain wall for a building facade, which It mainly includes a support frame 2 formed by conveniently separated and extending vertical uprights 3 without interruption for the entire height of the wall, these being joined vertical uprights by 4 horizontal crossbars that extend between these uprights at regular intervals according to the height of these last.

The uprights 3 and the crossbars 4 delimit this way in the support frame 2 a plurality of alveoli 5, open to the outside and destined to receive in a renvalso open that delimits each of these alveoli, panels 6, which in The example considered are glass panels, but also They could be solid panels. These panels, which are juxtaposed following the entire surface of the wall, they give it an aspect particular, with virtually no continuity solution, being separated the adjacent edges of the panels, at right angles with the uprights and crossbars for a minimum play that can hide in the end from the outside by slats or covers elongated decorative that will fit beyond the panels of glass on the armor.

Figure 2 schematically illustrates in section, a horizontal crossbar 4 of an armature 2, made in one way known in the art, this crossbar being associated with two 6 glass panels nearby, superimposed on the wall surface curtain, these panels being constituted in a classic way preferably by means of two parallel glasses 8 and 9, separated according to its periphery by an intercalated element 10. Finally, the two panels represented may present, depending on their location in the curtain wall surface, different dimensions and particularly different thicknesses from one panel to another.

In this embodiment, the cross member 4 includes a median extension 11, which extends horizontally between the two 6 panels represented, presenting this extension at its end directed towards the outside of the curtain wall a notch 12 with nerves or any other equivalent means of fixation, preferably to be manufactured with the profile that constitutes the crossbar, particularly by spinning this profile and in which a screw 13 can be attached to be fixed on the extension a support body 14, called a "bra", which It is part of the armor directly 2.

This fastener organ 14 extends over all the length of the corresponding horizontal crossbar 4 and is solidary by a plurality of screws distributed according to this length, which glass panels 6 will hold by their side external. These identical provisions, not represented in the Figure 2, but whose structure and role can be deduced immediately, they are provided for each vertical upright 3 of the support frame 2, such that the panels 6 are held in this mode on its four peripheral edges in each of the Alveoli 5, being completely immobilized there.

Sealing joints are planned, respectively 15 and 16, on each crossbar 4 (as in each upright 3) on the one hand, on the bra 14 on the other hand, being anchored these joints in appropriate channels 17 and 18 provided in the pieces facing so that they are applied against the glasses 8 and 9 in both parts of them, thus guaranteeing a tight block of the panels against the armor.

In the fastener organ 14, associated with each crossbar or reinforcement stile, can be placed next in the form of a clip or in any other way, a cover 19 exterior, which has only a decorative effect, which will hide screw 13 and fastener 14, marking the profile geometric of the curtain wall alveoli that receive the different glass panels 6.

This solution is long to execute and demands about all quantities of important materials as well as operations of relatively complex assembly.

Figures 3 to 5 illustrate the device perfected according to the invention, to effectively guarantee the clamping the glass panels of the curtain wall, avoiding these inconvenience

In these figures and as the case may be, thus a vertical upright 3, associated with at least one crossbar 4 horizontal, to delimit, similar to that already described, alveoli 5, which delimit an open renvalso that each one receives from the glass panels 6, housed in the corresponding socket and applying against the background of this renewal with support on a sealing gasket 20 (see figures 4 and 5), thus being these panels juxtaposed in the various alveoli of the armor of support that forms the outer surface of the curtain wall.

In this embodiment, the fastening of the panels 6 in alveoli 5, as well as the outward tightness of These panels are essentially guaranteed by means of organs 21 fasteners, which are distributed locally according to the dimension of each of the panels, being fixed in position on each of the horizontal crossbars 4, in combination with a profile 22 of Z-tightness, equally integral to these same crossbars. These fastener organs may be made of any material that has a rigidity and mechanical resistance sufficient, for example, of metal or of a rigid plastic material, of the genus polyamide.

If necessary, the fastening of the panels 6 in the alveoli 5 of the support frame 2 can be completed by means of organs 23 complementary fasteners, which rest on the lateral edges of the panels, allowing to fix these organs fasteners distributed locally according to the height of the uprights, as in the classic solution, on them, by the exterior, a decorative cover such as 24, not performing the same no function as regards the immobilization of The panels themselves.

As seen more particularly in the Figure 4, the cross member 4 shown includes an element 25 of support received by panel 6 located under this crossbar; resting this panel on this support 25 by means of a chock 26 thick allowing convenient adjustment against the armor two.

At right angles to extension 11 of the crossbar, in the notch 12 of the latter, is hooked, according to the invention, a bolt 27 that is part of the profile 22 of tightness in Z, which is thus integral to the crossbar and is going to cover the upper edge of panel 6 by its outer wing 28 housed in socket 5 located below it mentioned, in which the first panel 6 is mounted in support on the support 25.

This profile 22, advantageously realized from a appropriate elastic material, such as neoprene, PVC or a rubber EPDM type synthetic, is made to cover panel 6 located below the entire length of it, to prevent the rainwater flowing over the facade of the curtain wall 1 is filter in the alveoli 5 behind the panels 6 that the they contain.

In this way, the panels 6 are immobilized. by means of fastening organs 21, fixed in turn against the medium extensions 11 of the transoms 4, comprising advantageously each fastener a central plate 29 terminated by two Highlights such as 30 at the ends of this plate, highlights that they will be applied on the lower and upper edges of the panels 6 respectively located above and below the holding member, in the corresponding alveoli 5.

Likewise, advantageously, each organ 21 of clamping can include on its surface in front of a panel 6, particularly at right angles with the projections 30, which are in contact with the panel, an elastic covering (not shown) which prevents deterioration of the panel, particularly when it is glass.

The fastening of the panels can be completed with support of the complementary fastening organs 23, fixed according to the height of the uprights 3, as more particularly depicted in figure 3. These organs 23 include preferably, such as the holding members 21, a elastic coating on the parts that will contact the panel.

Advantageously, each holding 21 and / or 23 also includes external elbows 31 that allow the fixing of a decorative cover 24, analogous to that placed parallel on the support elements 23 associated with the uprights 3 Armor verticals.

As shown in Figure 3, the clamping bodies 21 may have the same profile as the support elements 23, only changing the means of fixing of these fasteners on the crossbars or the uprights respectively, as seen in figures 4 and 5 particularly.

Figure 5 completes the explanations given in the above, particularly as regards the respective function of the clamping organs 21 and 23, showing that the fixation of the panels on the armor only depends on them, regardless of the role that the latter can play also for the support of the decorative covers 24.

In this way, a simple device is made, which allows a significant saving of necessary materials and a Quick and safe assembly, perfectly guaranteeing this device in addition the efficiency of the assembly of the glass panels, obtaining the seal against the armor by the joints provided in the fund for the renewal of each cell receiving a panel of this type.

Of course, the invention is not limited in itself. same to the embodiment described more especially with reference to the attached drawings; on the contrary, it includes all variants.

In particular, none have been considered limitation as regards the material that constitutes the clamping organs 21 and 23. Particularly, these may be made of metal or in the form of injected pieces of material synthetic, for example, polyamide.

In addition, the clamping organs 21 and 23, considered in the described example, which maintain the panels of glass in several different points locally distributed, could be formed by means of a single piece that extends without interruption for the entire length of the crossbar, such as the profile 22 elastic Z-tightness, mounted on top of these panels.
