Description

GLASS SHOWCASES OF STRUCTURAL FACADES COMPRISING PANELS FORMED BY GLASS PLATES CARDS OF CELLS AND PERIMETER FRAME WITH PARTITIONS, SUITABLE FOR FIXING DIRECTLY IN THE BEARING STRUCTURES OF BUILDINGS FIELD OF THE INVENTION The invention relates to glass shop windows of structural facades of buildings comprising one or more panels formed by monolithic glass plates, laminated or glazed, lacking a perimeter frame with partitions and cells, called panels, suitable for fixing directly on beams, uprights, slabs and similar of load-bearing structures of buildings.

BACKGROUND OF THE INVENTION In modern architecture, glass has always found various applications in the coating of the increasingly varied facades of buildings. There is a constant search in the field in order to improve the aesthetics of such structures, visually eliminating the means of support and fixation of the individual plates, and simultaneously making the fixing of the plates safer to facilitate assembly.

Recently the glass walls have been very successful, in which the plates are held and fixed with means of fixing radial arms (called "spiders") that clutch portions close to the corners. Such a solution, while considered aesthetically pleasing in terms of the fixing means occupying a rather small visible space, has several disadvantages, in particular in the case of the window covering panels. These are used when you also want to obtain a certain degree of insulation from the exterior: the "glazing" panels are effectively formed by two parallel glass plates, separated from each other by a crack held dry through the interposition of a frame with dehumidifying material: the hole in the cover could effectively break the integrity of the panel and its services.

A technique has also been developed that allows holes to be made in a single plate of the window, but it is expensive and complex and even interrupts the integrity of the window. They use monolithic plates perforating them to introduce the "spiders", they are subjected to great tensions between themselves and the supporting structure.

In order to avoid perforation of the glass plates and to hide the fixing means of the glass plates, for many years the construction sector has made intensive use of glass-plate panels in which each one of the panels has a perimeter elaboration defined as a cell or cell that constitutes the partition.

Said cell is effectively composed of four contours of aluminum alloy (uprights and crossbars), anodized or varnished which are fixed rigidly to each other by their ends which thus form the four corners of the cell.

The resulting storefronts are defined as "structural facades", that is, facades that are completely glass, and incorrectly defined as "without partition" since visibly from the outside only glass is observed, which in 99% of cases is Reflected so as not to show the glass / frame perimeter elaborations. Said perimetral elaborations on the glass do not allow to see the base to which the glass adheres with special sealers, called structural silicones.

For safety reasons, given the type of "glass / silicone / metal" seal, the contours are subjected to specific tests, to ensure that the anodization or varnishing is compatible with the structural silicone, since the glasses, once adhered to the "cells" with the structural silicone, they come off the same "cells" falling to the floor with the consequent serious and serious injuries to people and objects. These cells represent the supports on which the glasses adhere, which are then closed like a skin on the buildings.

In order to improve the adhesion between the glass plates to these cells, the insertion in the profiling is used in the aluminum contours that make up the "cells", of a glass bar, "profiled" or rectangular, for fit in the contours of aluminum or to insert with "comfort", in order to obtain an optimal sealing of the type "glass / silicone / glass" given the greater affinity of the materials in contact.

Subsequently, the cell is fastened to a corresponding support frame (or counter-frame) formed by uprights and crossbeams, which in turn will be fixed by the beams of the supporting structure of the building.

This way glass windows are generated, the so-called "structural facades", or continuous facades, which show neither the outlines in sight between one panel and another, nor the external structures of the "spider" type.

Even this last solution also has some drawbacks in terms of the contours that form the cell of the panel and the relative support frame of the panels (coñtraarmazón) are not only noticed if the glasses are mirror or dark type thus preventing the realization of shop windows "luminous" formed by colorless glass plates.

Still the search for glass panels that present a structure of fixation to the supporting structure of the building is not very visible and limited by the fact that the panels must guarantee even the maximum possible security.

In practice, the growing demand in this sector is to be able to see out only the glass of the shop windows and hide as much as possible the metallic materials (cells, frames, etc.) that are used to immobilize the glass panels that form the windows, too in the case of panels formed by window panes.

SUMMARY OF THE INVENTION The object of the present invention is to provide showcases and the relative panels that form it in order to overcome the drawbacks of the existing technique, which can be placed on the work without requiring the use of means of fixation at sight and that do not need a structure of support and fixation to the supporting structure of the building that is visible from the outside in case of having non dark or colored glasses.

An additional objective is to provide such panels that are safe, easy to assemble, practical and economical.

An additional objective is to provide glass panels that can be fixed to the supporting structure of the building without making it excessively heavy, and which are provided with light means for fixing said supporting structure of the building.

Said objectives have been achieved with the invention as disclosed in claim 1. Further advantageous features are read in the dependent claims.

An object of the present invention forms showcases for buildings formed by one or more glass panels, suitable to be assembled together and fixed directly to the beams, uprights or slabs of the supporting structure of a building, where each panel is it is composed of a glass plate with no cells and a frame with partitions, and a first metal contour, fixed along a first short or long side of the back (on the surface of the panel facing towards the inside of the building) of said plate through means of silicone adhesions.

In the showcase, the first contour of each individual panel is housed, together with a first contour of another attached panel, in a suitable base extracted in a guiding contour that is linked with a beam, stile, IPE, slab, of the supporting structure. Said base is delimited by one or more wings that extend from the guide contour, which allow to retain at the base the first two contours with the help of fixing means that link said to the first contours of the two attached panels.

In addition to each panel, from the side opposite to that in which the first contour adheres, there is a glass beam or the like, or a second metallic contour adhered along the edge of a second short or long side in order to to be in parallel with said first metallic contour, to allow the fixation of the other side of the panel directly to the supporting structure.

In practice, the first metallic contour is suitable to be fixed directly to the beams (uprights, IPE, slabs, etc.) of the supporting structure of the buildings, which must contain appropriate bases in order to accommodate said contours, and link them with them.

In addition, said first contour preferably has a base suitable for mechanically retaining a glass rod and partially open towards the outside: in this way a zone of the glass rod comes into contact with the back of the glass plate of the panel so that it is possible realize a glass-glass adhesion with structural silicone thanks to which said first contour is adhered to the back of the panel through the use of structural silicone.

The beam, which is opposite the first metal contour, is also suitable for being linked by adding it to a glass shaft inserted in a second metallic contour or metal frame already present in the supporting structure of the building previously fixed to the beams (or stiles or slabs) of the structure.

In practice, analogously to what happens in the first contour, the glass shaft that has been inserted mechanically with clearance in a base of the second metallic contour, mounted on the structure carrier, is mechanically retained by the base (slot or contour chamber) which is also partially open towards the back of the panel, such that at least one area of said pole can come into contact with the back of the panel, in particular with the joist adhered to the back of the panel: once the two glass surfaces (of the shaft in the contour and the joist of the panel) are joined together, a silicone sealant capable of adhering both to the glass surface is inserted. A filler material is then inserted to fill the remaining spaces between the pole and its base.

Thanks to the layer of silicone adhesive, it is possible to carry out the so-called glass-glass fixing between the first contour (or the joist) and the plate, simultaneously providing two suitable areas for fixing them to the supporting structure of the building. Thanks to the use of this solution it is no longer necessary to drill the glass panels to fix them to the beams of the structure.

In practice, fixing operations are implemented on the dorsal (internal) face of the panel, also allowing a secure and solid fixation, the dismantling and reassembly of the individual plates, with the consequent cost advantage.

Alternatively to the glass beam attached to the back of the panel, it is possible to use a second metallic contour, equal to that of the first metal contour.

In practice, the first contour is suitable for working in pairs with a glass beam or a second metallic contour when both represent two zones on the panel in which the horizontal or vertical fixation of the individual panel can be carried out. existing bearing structure.

Preferably, the glass panel suitable for forming the showcase of the present invention is provided with a second metal profiled also provided with a base by an inserted glass shaft with set, said profile being able to adhere on the internal surface of the panel in order to be parallel to the first profile by means of the glass-glass coupling as indicated above.

These metal profiles are not attached or attached to each other but separated from each other: therefore, they do not form any partitions around the panel or a frame or cell (cell) to fix the facade reticle formed by the uprights and crossbars .

These profiles can be of different types and adhere on the surface of the glass plate of the panel that will be oriented towards the interior of the building, in order to be in parallel with the preselected sides and with the edge of the edges of said sides, using a silicone adhesive, as for example, structural silicone.

Said profiles can have the same length of the side or edge of the glass to which it has parallel, or, a length less than or greater than said side.

The two metal profiles parallel to each other of each of the panels are fixed directly on the beams (uprights, IPE, slabs, etc.) of the supporting structure of the buildings using fixation means or mechanical coupling systems, by For example, using steel screws that fix said profiles to a guide contour to C, to L, or that includes fins, integral with the vertical beams of the supporting structure of the building or with the horizontal beams. of the slabs, as will be described in detail below.

Consequently, without the help of a perimeter partition, without perforating the glass to be placed. the studs, without the perimetral clamps fixed to the glass, there is then the possibility of placing the panel of the present invention on previously placed structures (vertical facades, oblique facades, canopies and everything that considers the use of these panels). ? 1 panel suitable to form the showcase of the present invention can be composed of a glass plate, monolithic, or stratified, or by a window in which the fixation to the supporting structure of the building (uprights, IPE, slabs, etc.) takes place only with the help of a profiling and a direct glass, or two profiles as detailed above.

Preferably, the panel comprises two parallel glass plates joined together by a seal with a sealant sandwiched between them.

Preferably, the panel can be of various shapes and with pre-packaged glass, in order to have a manufactured module that can be easily placed on the work by hooking it directly to the vertical beams (uprights, IPE) of the supporting structure of the building to the horizontal beams of the slabs.

INVENTION In Figure 1, the panel according to the invention is globally indicated with the reference number 100. Said panel 100 according to the invention is formed by a grid 1 and by two profiles 2, parallel to each other, which therefore both do not generate partitions. Each profile 2 is preferably placed at the end of said panel 1 00 along the edge of the preselected side and on the inner face of the panel 100.

With the "sobrevidriera", which is also commonly referred to as "insulating showcase", is meant a panel comprising two or more glass plates with one or more bays of dehumidified air or gas, obtained with the intercalation between the plates of an optimum sealing provided by a sealant, preferably but not exclusively silicone. or structural silicone, and a frame that includes hygroscopic material.

With the "internal" face of panel 1 00 it is understood that the one destined to be oriented towards the support structure; with the "external" face of the panel 1 00 towards the view exposed to the solar rays (represented in the figures with letters).

In the implementation of Figure 1, the profiles 2 are preferably placed only on two of the sides of the panel 100, on the lower and upper end of said panel 100, and on the internal façade with the edges of the upper sides and lower. Said profiles 2 extend over the entire length of the upper and lower sides.

The position of the profiles 2, preferably with a number of two, on the surface of the panel is not binding with the objects of the present invention.

They are preferably arranged parallel to each other, and can be positioned indifferently along the short sides and / or along the long sides of said panel 100: for example, the profiles 2 can be placed to the right and left of said panel 100, instead of on the upper and lower sides as shown in the figure, and yet on any point of the glass surface of the inner face, and along any direction, based on the requirements of the supporting substructure.

Said overlay 1 and said profiles 2 se. they adhere preferably through a glass strip 10 by means, preferably but not exclusively, of silicone or structural silicone 4 that allows to connect said window cover 1 to said profiles 2.

The overlay 1 is known in the art: in the embodiment of Figure 1 it is formed by a monolithic external plate 6 and by a plate of stratified glass 3, which are separated by a spacer frame 9 and forming a bay 7. In addition, said plates 3 and 6 are preferably sealed to each other with structural silicone 8. Each profile 2 is fixed to the internal plate 3 by medium of a 1 0 glass strip using adhesion means 4 as defined above.

Without departing from what has been discovered by the present invention, the cover 1 can also be a cover 1 with one or more grooves with or without gas with two or more glass plates.

Said profile 2 is preferably implemented in metallic material and may include a continuous strip of glass 10 inserted into a C-shaped longitudinal span in cross section, made in profiling 2, which has the edges of the C rounded and oriented for a I stretch one towards the other. In the longitudinal spaced delineation of the C, the profiling 2 receives the glass strip 10. The strip 10 is received with play in the C-shaped span defined in the profile 2 and remains stable by the filling material (no shown in the figure). The filler material may comprise one or more of the following materials: sealants, silicone, mastics, patches, nylon sheets, etc.

The term "sealant" is intended to identify any material adapted to hold two glass plates together; "Silicone" is intended to identify an adhesive material made of silicone, as is normally used in the field of glass or other adhesive products.

The edges of the C of the profiling have a length such as to leave substantially exposed a long surface of the glass rod 10. This causes said rod 10 to adhere to the outer face of the inner layer 3 by means of the structural silicone filler. 4 placed between the internal plate 3 and the profile 2, making the profile 2 integral with said joint plate 3 in turn secured to the screen 1 by means of structural silicone 4.

The profile 2, preferably metal, may nevertheless have some parts and / or sections different from those reported in Figure 1 without departing from the scope of the present invention, eg, as the sections illustrated in Figures 2 and 3. .

In particular, the profiling can be a profile 2 'illustrated in Figure 2 mounted on a panel 101 with layered glass plate 3.

Otherwise, the profiling can be a tubular profile 2"of square or rectangular cross section, lacking plates 10, as shown in Figure 3 mounted on a panel 1 02 with stratified glass plate 3.

Each profiling 2, 21, 2"can be affixed to the continuous facade support framework or frame using traditional fastening means (not illustrated or described) which may also already be present on the back of said profiling s 2 , 2 ', 2".

Also the 2 'and 2"profiles, analogously to the profiles 2, can be placed on the glass plate of the panel, parallel to the preselected sides or in correspondence with the edges of the preselected data of the glass plate, and can have various adhesion systems, for example, silicones and / or other adhesives suitable for use, and with various mechanical latching systems not visible from the outside at the customer's choice, a glass / metal fabrication that nevertheless "does not partition "since said profiles are not joined or attached to each other, but separated from one another, said manufactured will then be fixed to the bearing substructures, created previously, by means of said profiles.

In addition, the perforations 2, 2 ', 2"may also have a shorter length than the side or edge of the panel 100, 101, 102 to which they are parallel, so that they may return relative to the perimeter of the manufactured leaving a free part of the internal surface of said manufactured.

As has been said, without leaving the scope of the discovered, the Overlay 1 in the detailed description mentioned above in relation to one embodiment, may be replaced by a laminated glass plate 3 as illustrated in Figures 2 and 3 which illustrate other embodiments of manufacture 101 and 102 according to the present invention; in the embodiments illustrated in Figures 1 -3 the overlay 1 or the laminated glass 3 can also be substituted with a monolithic glass without departing from that discovered by the present invention.

The placement of one or more profiles 2, 2 ', 2", preferably two, that do not make framework or partitions, ie a) on the surface of the insulating glasses with air chamber of various compositions, types, thicknesses, etc.; b) on the surface of monolithic glasses of various compositions, types, thicknesses, etc.; it will be carried out in accordance with the requirements of the load-bearing structures and the relative hooks, present on the support structure.

As it has been said with the expression "do not make frame or partitions" it is intended that the profiles, when they are more than one, are not joined or attached to each other as it happens instead in a framework or partitions. This represents a notable advantage of the manufactured product of the present invention since the final manufactured is lightened with respect to those known because it does not include the framework generally necessary for its attachment to the supporting structure or frame, also having secure fixing means such as said profiles. In addition to that said profiles represent a system of secure mechanical engagement for said glasses but not visible from the outside.

The present panel 100, 101, 1 02 can be easily prepackaged with the profiling 2, 2 ', 2", which optionally also comprises the 1 0 strip, in glass so that it can be assembled in succession and linked easily to the supporting framework on site. belonging to the building.

The panel 100, 1 01, \ 02, is remarkably attached to a support structure not illustrated in the figure for simplicity of the graphic representation.

The panel 100, 101, 102 of the present invention allows to have an optimum sealing for the external panel / showcase plate in all the periphery thereof, with optimal working conditions thanks to the structural silicone 8, also in the case of breakage of the internal plate 3 of the sobrevidriera.

The manufactured one is in the form of a panel 100, 101, 102 according to the present invention, it can be used as a "SKIN" for the coating of buildings (vertical walls, oblique walls, roofs, etc.) but also for the protection of bays. stairs, vain elevators, etc., in practice where its application becomes necessary.

With reference to Figure 4, the attachment to the supporting structure of the building of two glass panels placed adjacent to one another is described below.

Each panel 104 is formed by a layered glass plate 3 and includes metal profile 2 ', analogous to that reported in Figure 2, which in turn includes a glass beam 10 capable of adhering to the internal surface of the plate 3 (that is, the one facing the interior of the building and opposite the rays indicated in the figure by means of arrows) using structural silicone 4.

In particular, said profiling 2 'has a tubular body 11 from which, for the entire length of the profiling 2, a flange 12 parallel to the beam 10 defines a base or channel for said beam 10 along the entire length of the beam. profiled 2 '.

The channel is placed before said tubular body 11 and is capable of mechanically retaining the glass beam 10 by said wing 12. This beam 10 is joined together with the plate 3 of the panel through a layer of silicone adhesive 4, called "structural silicone".

The profiling 2 'is fixed to the plate 3 in the vicinity of the edge of the its short side or long side and extends all along said side.

Each of the first two profiles 2 'belonging to a respective panel 1 04, is collected in a base 13 defined by the wings 14 of a C-shaped contour with the function of. guide contour, which is part of the beam IPE 1 6 of the supporting structure.

Each flange 14 of the contour 1 5 is then adjacent to the side walls of each profiling 2 '. A screw 1 7, which includes the respective self-locking die, passes through the wings 14 and the tubular bodies 1 1 of the two attached profiles V, fixing these two profiles 2 'and also the two profiled ones 2' to the guide contour 1 5 to the supporting structure 16 of the building.

Each screw 1 7 is also provided with respective fittings to ensure a good tightening of the profiles 2 'to the wings 14.

In practice, the two profiles 2 'are introduced to the relative base 1 3 of the C-shaped contour 15 and then the wings 14 and the walls of the tubular body 1 1 of each are perforated. 2 'profile in order to insert a set screw 17.

Said screw 1 7 are furthermore placed at distances prefixed longitudinally along the C-shaped contour 5 so as to fix the profiled parts 2 'to the said guide contour 1 5 and consequently to the supporting structure 1 6 at more points.

In the base 1 3, below the profiles 2, a transparent insulating material, for example polycarbonate, is preferably placed, suitable for insulating the profiles 2 with respect to the supporting structure of the building, in particular for electrically insulating them.

In practice, according to the method of construction of the showcases of the invention, the two panels 104 of layered layer 3 and the first respective profiles 2 remain fixed to the supporting structure 16 of the building thanks to the guide contour 1 5 integral with the supporting structure 16.

In order to correctly place each panel 104 in the façade, it is preferably considered to leave between the adjacent panels 1 04 a crack 18 for sealing in a traditional manner with structural silicone 4 and / or insulating material 21 (Figure 5), after having inserted a joint 1 9 suitable to distance the panels and allow different thermal expansions between the glass plate and the metal supports.

It can be seen that the fixation means (screws, profiles and the like) and fixation operations that include only the glass surface of the panel oriented inwards of the building (back), so that the facade of the structure can be designed to satisfy only aesthetic canons.

Furthermore, with the fixation method of the invention, glass panels can be fixed without danger of deteriorating them or creating thermal bridges.

Without departing from the spirit of the present invention, the showcases of the present invention can be implemented, through the assembly described above, also using the different panels of Figure 4, for example, panels formed by layers of overlay, as shown in Figure 5, which include metal profiles 2 (as shown in Figure 1) affixed to an existing supporting structure 16 in cement or another, to which the C-shaped guide contour has previously been fixed. 15, or use the cover plates with stratified glass. It is also possible to use the metal profiles with a cross section different from that of the profiles 2 and 2 ', for example, of rectangular cross section, semicircular, or other, provided that it includes at least one fin 12 suitable for retaining at the base a glass shaft 10 as described above.

On the other hand, the guide contour 1 5 which is part of the supporting structure 1 6, as in the case of the IPE, can be an element that is properly fixed before the different types of structures carriers 16 for buildings, for example, beams or studs. Said fixation can be implemented by welding if the existing structure 16 is made of metal, or, using suitable fixing means in the case where the supporting structure is made of cement or reinforced concrete; or, said base can be implemented in the existing load-bearing structure by any means.

In addition, the guide contours 1 5 can be L-shaped instead of C without departing from the spirit of the invention.

Referring to the panels of Figures 4-5, on the opposite side to which the profiling 2,2 'adheres, a glass beam 30 (shown in Figure 6) can be adhered instead of a second profiled 2,2'.

With the term "glass beam" it is understood to identify a beam formed by any compound. based on silica, fiberglass, ceramic, vitrified varnish, etc. that has physical and / or chemical characteristics similar to those of glass. Consequently, the joist can be defined as made of "glass or similar".

Such joist 30 is capable of being coupled, by means of the elastic silicone sealant 4, to a metal profile similar to that of profiling. 2,2 'described above, or, to another type of metal profiling 3 1, which is part of a metallic framework capable of supporting one. glass plate and that is part of the supporting structure of the building. In particular, said profiling 3 1 must be equipped with at least one internal housing 32 in the form of C or L, generated by two opposing fins 33, or by an elongated fin, in order to retain a delirium shaft 34, accommodated previously in said housing with fire, you must then insert an elastic filling material 35 as a garniture, nylon strips, adhesive tapes, patches or seals.

The insertion of said glass rod 34 and its clutch with the glass beam 30 adhered to the back of the panel 1 06 (with the monolithic plate) can be implemented in a manner analogous to that described in the patent application WO 89/04416 which is incorporated integrally for reference.

In practice, once in the profiling 3 1 the glass rod 34 has been inserted and has remained solid with the profile 3 1 as established previously, the beam 30 is adhered to the glass rod 34 and fixed mechanically to the profile 3 1 by applying structural silicone on the surface 36 of the beam 30 facing the surface 37 of the shaft 34 inserted in the profile 3 1.

As has been said, alternatively to the glass beam 30, the panels of the present invention can be equipped with a second profile 2.2 ', adhered along the opposite side to where the first profile 2.2' is placed by means of the application of structural silicone 4 on the surface of the joist 30 facing the surface of the shaft 10 inserted in the second profile 2, 2 '.

It should be noted that the metal profiling 2 and / or 2 'on the panel 100, 101, 102, 104, 105, 106 can be set delayed with respect to the edge of the preselected side of said glass plate. The same can be applied to the placement of the glass joist 30.

It should be further noted that it should be further noted that each metal profiling 2,2 'and / or glass beam 30 may have a dimension smaller than that of the pre-selected setting side.

The shop windows of the present invention formed by the panels described above can also be business showcases formed by a single glass panel having the dimensions of the showcase. In this case, the profile 2.2 'will be present on one of the two horizontal sides and will be fixed to the beams of the slab or the pavement, if the weight of the panel can be discharged directly to the ground. In this case on profiling 3 1 it is preferable to provide a value of support 38 of the panel, analogously to that described in WO 89/0441 6 which is integrally incorporated for reference.

On the other hand, in the case of the windows of buildings formed by a plurality of glass panels, the so-called panels are used one on the other provided that the structure therefore of the building, beams or slabs, includes a support plate 22 and a longitudinal metal reinforcement profile 23 as illustrated in the vertical cross section of Figure 7. The support plate 22 preferably has a length such that it allows the profile 2 to completely rest on said plate by unloading on it the agent weight on the panel. For each panel below it is preferable to provide a thickness 24 for the correct positioning of the panel which in Figure 7 is illustrated as the panel 1 05 of laminated plates with laminated plates, although it is not binding with the objectives of the present invention.

The showcase of the invention also allows to have an optimum sealing throughout the periphery of each of the panels also guaranteed by the transparent silicone seal between the panels.

In addition to the fact that the manufacture of shop windows according to the present invention makes it possible to have more secure windows in terms of the accidental removal of a panel from the supporting structure, it is unlikely given that the fixation between the glass strips and the metal frame allows dilatations and differentiated contractions due to mechanical stresses or temperature variations thanks to the presence of a set and an elastic adhesive.

In fact, to allow relative dilation between the glass strips or the like and the metal frame, the dimensions of said strips are slightly smaller than those of the housing in which the strip is picked up and the open spaces are filled with a sealer or similár (small strips of nylon, adhesive tapes or patches).

Thanks to the application of panels as described above it is possible to avoid the application of the facade grid formed by uprights and crosspieces necessary to be able to build a showcase with the known panels equipped with a cell or with a perimeter frame.

Without departing from the scope of the discovered, an expert technician can provide the present invention described above all the modifications and improvements suggested by their normal experience and / or by the natural evolution of the technique.
