- presser a relative first element
- a second covering element to hide the heads of the screws and the anti-aesthetic parts of the first element.
- Another disadvantage is that the condensation that forms and the water that filters, especially in the cross-pieces, tends to stagnate between the cross-piece and the closure profile, creating problems connected to infiltrations of water and humidity inside the wall, and the consequent formation of mold or otherwise.
- curtain walls and methods to assemble such curtain walls, which have the features of, respectively, the preamble of independent claims 1 and 8, are disclosed in US-A-5,839,236 , US-A-4,672,784 and EP-A-644.311 .
- One purpose of the present invention is to perfect an assembly method which allows to assemble rapidly and without needing prior holes a closure profile onto uprights and cross-pieces of a curtain wall. Another purpose is to achieve a curtain wall provided with constraining means that allow a rapid and simple attachment of the closure profile with the relative cross-piece and/or upright and, at the same time, an effective discharge of the filtered water and the condensation that has formed inside the elements of the reticule of the curtain wall.

- the method to assemble the closure profiles provides, after having assembled the relative covering sheet, a first step wherein the closure profile is coupled frontally with the relative segment of curtain wall, engaging its second attachment means with the first attachment means of the relative cross-piece or upright.
- a first sealing means, or packing is associated with a first edge of the closure profile, and is taken into contact with a relative covering sheet.
- the closure profile is rotated, in a direction from the inside towards the outside with respect to the curtain wall, around an axis that passes substantially through the point of engagement of the first and second attachment means, exploiting the partial elastic deformation of the first sealing means that is pressed against the sheet.
- a second sealing means is positioned in correspondence with the second edge of the closure profile opposite the first, and rests upon another covering sheet, thus defining the stable assembly position of the profile.
- the first attachment means associated with the cross-piece or upright consist of a strip, or bar, arranged longitudinally parallel to the relative cross-piece or upright; the strip is provided, along at least part of its inner edge, with a shaped profile that is configured to be inserted in snap-in manner into a mating seating, partly hollow, made on the relative upright or cross-piece.

- the strip in an intermediate position between the outer edge and the inner edge, defines a longitudinal hollow that functions as a conveyor and channel for the water and condensation.
- the assembly method described above allows a rapid and simple snap-in assembly of the closure profile with front coupling, in a single operation and without needing previously made holes. Moreover, the conformation of the attachment means provided in the uprights and/or cross-pieces of the curtain wall encourages a rapid outflow of the filtered water, thus preventing the formation of mold or infiltrations into the curtain wall itself.

Abstract
Description
- The present invention concerns a method to assemble curtain walls for buildings, and a curtain wall assembled with this method.
- Curtain walls for buildings generally comprise a reticular supporting structure, consisting of uprights and cross-pieces, on which the covering elements are assembled, for example glass panels or sheets, or other suitable material.
- The uprights and cross-pieces consist of metal profiles, generally made of aluminum, with which supporting means are associated in order to position and attach the covering elements.
- On the visible side of the wall, in order to close the horizontal and vertical gaps that form between adjacent sheets, closure profiles or stoppers are generally assembled. To apply a closure profile of a known type, however, it is necessary to screw in a relative first element, known as presser, to the uprights and cross-pieces, with a screw about every 20 cm, and then apply in snap-in manner a second covering element to hide the heads of the screws and the anti-aesthetic parts of the first element. This entails both the need for prior holes on the presser elements and also a double operation during the assembly step, with a consequent extension of the execution times.
- Another disadvantage is that the condensation that forms and the water that filters, especially in the cross-pieces, tends to stagnate between the cross-piece and the closure profile, creating problems connected to infiltrations of water and humidity inside the wall, and the consequent formation of mold or otherwise.
- Curtain walls, and methods to assemble such curtain walls, which have the features of, respectively, the preamble of independent claims 1 and 8, are disclosed in
US-A-5,839,236 ,US-A-4,672,784 andEP-A-644.311 - One purpose of the present invention is to perfect an assembly method which allows to assemble rapidly and without needing prior holes a closure profile onto uprights and cross-pieces of a curtain wall. Another purpose is to achieve a curtain wall provided with constraining means that allow a rapid and simple attachment of the closure profile with the relative cross-piece and/or upright and, at the same time, an effective discharge of the filtered water and the condensation that has formed inside the elements of the reticule of the curtain wall.
- The Applicant has devised, tested and embodied the present invention in order to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
- The present invention is set forth and characterized in the main claims, while the dependent claims describe other features of the invention or variants of the main embodiment.
- According to the invention, the cross-pieces and/or uprights of the curtain wall include first attachment means with which second attachment means cooperate, said second attachment means being provided in the closure profiles in order to obtain a rapid reciprocal snap-in attachment. The first attachment means face towards the outer side of the curtain wall and are arranged in the gap that forms between two adjacent covering sheets.
- Here, and in the following description, with the term "inner" we mean the side of the curtain wall, or of parts thereof, which faces the bearing structure of the building, while with the term "outer" we mean the opposite side.
- To be more exact, the method to assemble the closure profiles provides, after having assembled the relative covering sheet, a first step wherein the closure profile is coupled frontally with the relative segment of curtain wall, engaging its second attachment means with the first attachment means of the relative cross-piece or upright. A first sealing means, or packing, is associated with a first edge of the closure profile, and is taken into contact with a relative covering sheet. Then, the closure profile is rotated, in a direction from the inside towards the outside with respect to the curtain wall, around an axis that passes substantially through the point of engagement of the first and second attachment means, exploiting the partial elastic deformation of the first sealing means that is pressed against the sheet. Finally, a second sealing means is positioned in correspondence with the second edge of the closure profile opposite the first, and rests upon another covering sheet, thus defining the stable assembly position of the profile.
- In one form of embodiment, the first attachment means associated with the cross-piece or upright consist of a strip, or bar, arranged longitudinally parallel to the relative cross-piece or upright; the strip is provided, along at least part of its inner edge, with a shaped profile that is configured to be inserted in snap-in manner into a mating seating, partly hollow, made on the relative upright or cross-piece. At least part of the outer edge of the strip comprises said first attachment means which, in a preferential embodiment, are shaped substantially like a hook extending outwardly, and are able to cooperate with said second hook-shaped attachment means provided on the inner side of the closure profile.
- The strip is preferentially made of plastic material and, apart from its function as an attachment element for the closure profiles, it also has the function of a thermal bridge in order to limit the transmission of hot or cold between the inside and outside of the curtain wall.
- According to the resent invention, on the ends of each cross-piece there is a stopper element on which at least a drainage hole is made, from which the water that accumulates and/or filters inside the cross-piece can drain. The cross-piece, in correspondence with this drainage hole, has a shaped part along which the inner condensation collects, in order to be discharged through the drainage hole provided on the stopper element and from here through a relative upright.
- At least a discharge platelet is also provided, arranged as an extension of the strip defining the attachment means for the closure profile and below the drainage hole; the platelet is shaped so that the water and condensation that drain both from the strip and also from the channel of the cross-piece through the drainage hole are conveyed towards the adjacent upright, which therefore performs a substantial function as a gutter and downspout, and through this are discharged downwards.
- According to the invention, in an intermediate position between the outer edge and the inner edge, the strip defines a longitudinal hollow that functions as a conveyor and channel for the water and condensation.
- The assembly method described above allows a rapid and simple snap-in assembly of the closure profile with front coupling, in a single operation and without needing previously made holes. Moreover, the conformation of the attachment means provided in the uprights and/or cross-pieces of the curtain wall encourages a rapid outflow of the filtered water, thus preventing the formation of mold or infiltrations into the curtain wall itself.
- These and other characteristics of the present invention will become apparent from the following description of a preferential form of embodiment, given as a non-restrictive example, with reference to the attached drawing wherein:
-
fig. 1 is a three-dimensional view of a curtain wall according to the invention; -
figs. 2a and 2b show respectively in transverse and longitudinal section part of the curtain wall infig. 1 ; -
figs. 3a-3d show four steps of the method to assemble the closure profile in the wall according to the invention; -
fig. 4 shows a step to assemble a stopper element to a cross-piece of the curtain wall infig. 1 ; -
fig. 5 is a three-dimensional view of a cross-piece of the curtain wall infig. 1 ; -
fig. 6 is a perspective view of a coupling segment between an upright and a cross-piece functioning as a condensation collector in the wall according to the invention. - With reference to
fig. 1 , acurtain wall 10 consists of a reticular supporting structure comprising a plurality ofuprights 11, arranged in use substantially vertical, and a plurality ofcross-pieces 12 arranged in use substantially horizontal. - In the quadrangular spaces defined between the
uprights 11 and thecross-pieces 12, covering panels, forexample glass sheets 13, are assembled. To be more exact, as shown infig. 2a , in correspondence with arelative cross-piece 12 everyglass sheet 13 has a lower edge resting on a supportingblade 15, while the upper edge of theadjacent sheet 13 is elastically clamped by aretaining blade 16. Theblades cross-piece 12; they are only shown infig. 2a , whereas they have been omitted from the other figures to facilitate understanding. - On the front side of the
curtain wall 10closure profiles 17 are assembled, arranged horizontal and vertical to cover the gaps that form between twoadjacent glass sheets 13. - In this case, each
closure profile 17 has a substantially T-shaped transverse section with the leg of the T-shape facing towards the inside, and its central leg ends in ahook 19 facing downwards. Theclosure profile 17 also has afirst edge 25 on which afirst packing 26 is able to be assembled in snap-in manner, and asecond edge 27, opposite the first, on which asecond packing 29 is able to be mounted also in snap-in manner. The twopackings relative glass sheets 13, so as to prevent water from filtering inside theuprights 11 and/orcross-pieces 12. - On every upright 11 and on every
cross-piece 12, for the whole of their length, astrip 20 is assembled on whose inner edge ashaping 21 is provided for a snap-in attachment; on the outer edge of thestrip 20 there is ahook 22 facing upwards and mating in shape with thehook 19 provided on theclosure profile 17. - The
strip 20, advantageously made of plastic material or in any case partly elastic, is inserted in snap-in manner inside amating housing seating 23, at least partly hollow and open towards the outside, made in a central zone of every upright 11 and/orcross-piece 12. - Between the shaping 21 and the
hook 22 thestrip 20 has a longitudinal hollow 30 functioning as a channel to discharge the filtered water and the condensation that has formed. Thelongitudinal hollow 30 is located in a substantially intermediate zone between theblades relative strip 20. - Each upright 11 and each
cross-piece 12 also include, located in a known manner in hollows provided in the relative front edges, twopackings 31 associated with the inner side of thesheet 13. - At the lateral ends of each
cross-piece 12 there are two stoppers 32 (figs. 2b ,4 and5 ), attached by means ofassembly plates 33 and including a throughdrainage hole 35, and adischarge platelet 36 arranged as an extension of thestrip 20 and below thedrainage hole 35. - The
assembly plates 33 include threadedholes 42 into which respectivegrub screws 43 are inserted (figs. 2b and4 ) that press against a vertical wall of therelative cross-piece 12. - The
assembly plates 33 also include anattachment tooth 40 that anchors on a mating tooth-like profile of the relative upright 11 and that ends frontally in a wedge-shaped segment 34, arranged outside therespective stopper 32; thesegment 34, by inserting agrub screw 41 in a threadedhole 44 provided in a position adjacent to theattachment tooth 40, takes thestopper 32 mounted on thecross-piece 12 to press against the upright 11. - The sequence to assemble the
cross-pieces 12 to theuprights 11 provides firstly to insert thestopper 32 at one end of thecross-piece 12, inserting theplates 33 into the respective seatings and clamping them in contrast with the pre-assembledgrub screws 43; then, thecross-piece 12 is inserted on the upright 11, attaching thetooth 40 and completing the coupling by means of pressure tightening thepre-assembled grub screw 41. In this case too it can be seen that the assembly of the components of thewall 10 does not require any prior operation to make holes, and is carried out with extremely simple and rapid operations. - The drainage hole 35 (
fig. 5 ) is located in correspondence with a collection anddischarge channel 37, defined by a shaping provided in the upper part of thecross-piec 12 on which thestopper 32 is assembled. - The
platelet 36 has a raisededge 39 and has its base surface horizontal or, according to a variant, slightly inclined towards the inside, so as to convey inside arelative upright 11 both the water that flows on the base surface of thestrip 20, and also that which collects in thechannel 37 and which drains through thehole 35 of thestopper 32. - With this solution, the water and condensation do not stagnate inside the
cross-pieces 12 but are quickly and constantly discharged. -
Figs. 3a, 3b, 3c and 3d show the sequence of assembly of aclosure profile 17 with respect to arespective upright 11 and/orcross-piece 12, subsequent to the positioning of therelative sheets 13. - The figures describe the assembly with respect to a
cross-piece 12, but the assembly of the profile on anupright 11 is substantially identical, wherein the meaning of the terms "up" or "down" and derivatives thereof must be read as "right" or "left" and derivatives thereof. - Firstly, after having positioned the relative
upper sheet 13 resting it on the blade 15 (seefig. 2a ), theclosure profile 17 is inserted frontally, slightly inclined downwards with respect to thecross-piece 12, with thehook 19 arranged in this case above thehook 22 of thestrip 20, and with the upper packing 26 assembled on a firstupper edge 25 in contact with the respective upper glass sheet 13 (fig. 3a ). - In the following step (
fig. 3b ), thehook 19 of theclosure profile 17 is engaged with thehook 22 of thestrip 20, and theclosure profile 17 is rotated from the inside to the outside, pivoting on thehook 19. The rotation is allowed by the elastic deformation of theupper packing 26 when pressed against therelative sheet 13. At the end of this operation (fig. 3c ), a second lower packing 29 is inserted on the secondlower edge 27 of theprofile 17, in such a manner (fig. 3d ) as to stabilize the position of theprofile 17 with bothpackings respective glass sheets 13. - It is therefore simple and quick to assemble the
profile 17, it requires only a single operation and does not need any previously made holes. - If water should filter through the
packings cross-piece 12, this is discharged flowing through thechannel 37, thehole 35, theplatelet 36 and/or the hollow 30, and is then conveyed inside therelative upright 11; this considerably reduces the risk of mold forming inside thecurtain wall 10. - It is clear, however, that modifications and/or additions of parts or steps may be made to the
curtain wall 10 and the assembly method as described heretofore, without departing from the field and scope of the present invention. - For example, the two
hooks strip 20 to therelative upright 11 orcross-piece 12 can also be achieved with equivalent means to those shown here. The grub screws 41 and 43 could be replaced by pins, blocks or other identical or equivalent clamping means. - Although a solution is shown here wherein there are two
