Modular structural facade

Description

[0001] The present invention relates to a modular structural facade and an assembly kit of a modular structural facade.

[0002] In particular, it is known in the art to make structural facades from modular panels, called "cells", preassembled in the assembly plant and then installed on site.

[0003] The cells are attached to a load-bearing structure of the building. This means that by means of horizontal and vertical dilation joints, each cell is independent of the others both as regards its own dilation and in relation to settlement or seismic movements of the building itself, thereby preventing breakage of the elements composing it (glass panes, aluminium).

[0004] The cell is normally composed of a perimetral, metal structure and of infill panels. The perimetral structure is usually in aluminium and the infill panels can be visual glazing, blind glazing with insulation panel, in aluminium, marble etc.

[0005] The infill panels of the visual parts may be fixed or openable, according to the user's needs.

[0006] The cells of the prior art have a number of drawbacks and disadvantages.

[0007] For example, while the external aesthetics of the cells maintain the typical appearance of structural facades, the internal appearance of the cells, in other words from the inside of the structure or building, has visible metal portions not always to the user's liking.

[0008] Moreover, the performance in terms of heat and noise insulation of the structural facades of the prior art are not optimal or in line with the increasingly rigid demands of the market as regards international energy parameters.

[0009] Moreover, the structural facades of the prior art are not particularly fire-resistant. An example of these facades with the above cited drawbacks, disclosing all the features of the preamble of claim 1, is known from EP 0 436 868 A2.

[0010] The present invention therefore sets out to resolve the drawbacks mentioned with reference to the prior art.

[0011] Such limitations and drawbacks are resolved by a structural facade according to claim 1.

[0012] Other embodiments of the present invention are described in the further claims.

[0013] Further characteristics and advantages of the present invention will be more clearly comprehensible from the description given below of its preferred and structural facade according to one embodiment of the present invention;
figure 2 shows a cross-section view of the facade in figure 1, along the section plane II-II of figure 1;
figure 3 shows a schematic view of an industrialised production method of a structural facade according to the present invention;

[0014] The element or parts of elements common to the embodiments described below will be indicated using the same reference numerals.

[0015] With reference to the aforementioned figures, reference numeral 4 globally denotes a structural facade or a portion of a structural facade, for buildings and the like, comprising a plurality of cells 8. The cells 8 are usually attached to the load-bearing structure of the building so as to make the external facade.

[0016] For example, the cells are a quadrangular, rectangular or square shaped and each comprises a pair of uprights 12 and a pair of crossbeams 16. The uprights 12 and the crossbeams 16 are preferably perpendicular to each other. Adjacent cells 8', 8" are positioned alongside each other at adjacent uprights 12', 12" or crossbeams 16', 16".

[0017] The cell 8 comprises a structural frame having a pair of uprights 12 and a pair of crossbeams 16 so as to form a structure closed around the perimeter delimiting a perimetral compartment 20 suitable to be closed by external glazing 24 mechanically associated to the frame on an anterior face 28 of the latter.

[0018] The anterior face 28 of the frame of the cell 8 is destined to be positioned on the outside of the building so as to constitute the facade itself.

[0019] The external glazing 24, depending on the type of cell, may be fixed, openable, visual, blind. For example it may comprise a glass pane or even an opaque panel, in any material.

[0020] Advantageously, the uprights 12 and the crossbeams 16 comprise a load-bearing metallic core 32 which supports and lends structural rigidity to the cell.

[0021] The metallic core 32 comprises means of attachment 36, for the support and attachment of the glazing 24 to the structural frame, the means of attachment 36 being positioned on the side opposite the perimetral compartment 20.

[0022] For example, the means of attachment 36 comprise screws, pins, wall plugs and similar.

[0023] According to one embodiment, the glazing 24 is attached with gluing and structural sealing to a small support frame 40; said small support frame 40 being attached on the anterior face 28 of the metallic core 32 by said means of attachment 36. In other words, the means of attachment block the glazing 24, by means of the small support frame 40, directly onto the metallic core 32 of the cell 8.

[0024] Advantageously, the uprights 12 and the crossbeams 16 each comprise at least one cheek panel 44, directly facing said perimetral compartment 20, on the side opposite the means of attachment 36 of the external glazing 24. The cheek panel 44 is preferably in wood; a non-metallic material may also be envisaged having insulation properties and good fire-resistance so as to protect the metallic core which it covers.

[0025] The cheek panel 44 covers the metallic core 32 on the side of the perimetral compartment 20, at a lateral rim 48 of the perimetral compartment 20, and also covers it from the inner side 52 at the rear face 56 of the frame, opposite the associable glazing 24 and the anterior face 28, so as to increase the resistance to fire, as well as the heat and noise insulation of the cell 8.

[0026] The cheek panel 44 is bound to the metallic core 32 of the crossbeams 16 and of the uprights 12 by means of shaped couplings 60 and/or gluing means 64.

[0027] According to one embodiment, the shaped coupling means 60 comprise joints between at least one protuberance 68 made preferably on the metallic core 32 and at least one groove 72, counter-shaped to the protuberance 68, made preferably on an inner face 76 of the cheek panel 44, directly facing the metallic core 32.

[0028] The protuberance 68 and the groove 72 can also be positioned in an inverted manner, that is the protuberance can be positioned on an inner portion of the cheek panel 44 and the groove 72 can be made on the metallic core 32.

[0029] Preferably, the protuberance 68 and the groove 72 have a main longitudinal extension, in a vertical direction Y-Y for the uprights 12 and in a horizontal direction X-X for the crossbeams 16, so as to bind the metallic cores 32 and cheek panels 44 to each other in a transversal direction Z-Z, perpendicular to the horizontal X-X and vertical Y-Y direction, and so as to enable relative sliding between the metallic cores 32 and the cheek panels 44 parallel to said respective horizontal X-X and vertical Y-Y directions.

[0030] The shaped coupling means 60 enable easy alignment of the profiles of the uprights 12 and of the crossbeams 16, as well as enabling the wood to collaborate structurally with the metal, preferably aluminium, improving the final inertia of the cell 8. Moreover, said shaped coupling means 60 make it possible to prevent the coupling from becoming purely structural as a result of the resulting complexity of identifying a sealing agent which assures tightness, given the complex nature of wood and its behaviour. In other words, said shaped coupling means, as mentioned above, permit relative sliding between the metallic core 32 and the cheek panel 44.

[0031] Preferably, between an inner face 76 of the cheek panel 44, directly facing the metallic core 32 and the metallic core 32 itself, a chamber 80 containing said gluing means 64 able to glue and seal the cheek panel 44 and metallic core 32 to each other is defined.

[0032] According to one embodiment, said chamber 80 has a constant predefined thickness and the gluing means 64 have a higher elasticity modulus than the materials of the cheek panel 44 and the metallic core 32 so as to allow and absorb the different dilations of the two coupled materials.

[0033] According to one possible embodiment, the protuberance 68 has a wider part 84 at the portion of attachment to the metallic core 32 so as to identify a limit stop to the insertion of the protuberance 68 in the groove 72 and guarantee the presence of a chamber 80 for the containment of the gluing means 64.

[0034] Preferably, the gluing means 64 have a temperature resistance of up to 200°, so as to ensure the mechanical connection of the cheek panels 44 and the metallic core 32 of the frame, up to the structural resistance limit of the metallic frame.

[0035] As mentioned above, the cells 8 are positioned alongside each other both in a horizontal direction X-X, by drawing together and joining respective adjacent uprights 12', 12" to each other and in a vertical direction Y-Y by drawing together and joining respective adjacent crossbeams 16', 16" to each other.

[0036] The mechanical connection of the uprights 12', 12" and the crossbeams 16', 16" is performed by means of joints 88 fitted with undercuts in an axial direction Z-Z perpendicular to the associable glazing, and perpendicular to the horizontal direction X-X and the vertical direction Y-Y.

[0037] Preferably, at the connections between the uprights 12 and/or the crossbeams 16 of cells 8 adjacent to each other, intumescent tapes 92 are inserted to improve the resistance to fire of the facade 4. In particular, said intumescent tapes 92 are used to protect the zones most at risk of sparking a flame, such as corners, untreated or more exposed parts of the cell 8.

[0038] According to one embodiment, the cells according to the present invention are supplied in an assembly kit.

[0039] The kit comprises at least one pair of uprights 12 and a pair of crossbeams 16 each comprising a load-bearing metallic core 32, comprising means of attachment 36 of the external glazing 24, and at least one cheek panel 44 in wood, opposite said means of attachment 36. In particular, inside the assembly kit the cheek panel 44 is preassembled to the respective metallic core 32 by means of shaped couplings 60 and/or gluing means 64.

[0040] The shaped coupling means 60 comprise joints between at least one protuberance 68 made on the core and at least one groove 72, counter-shaped to the protuberance 68, made on an inner face 76 of the cheek panel 44, directly facing the metallic core 32.

[0041] Moreover, the preassembly envisages that between an inner face 76 of the cheek panel 44, directly facing the metallic core 32 and the metallic core 32 itself, a chamber 80 containing said gluing means 64 able to glue and seal the cheek panel 44 and metallic core 32 to each other is defined.

[0042] As a result, the kit envisages that the uprights and the crossbeams are preassembled so as to associate each cheek panel 44 to the respective metallic core 32.

[0043] Moreover, the uprights 16 and the crossbeams 12 are shaped so as to form, in an assembled configuration, a structure closed around the perimeter which delimits a perimetral compartment 20 suitable for being closed by the external glazing 24 mechanically associated to the frame on an anterior face 28 of the latter.

[0044] The method of making and installing a cell and a structural facade according to the invention will now be described.

[0045] In particular, The method of making and installing a structural facade 4 composed of cells 8 according to the invention comprises the initial steps of cutting to size and supplying metallic cores 32 and relative cheek panels 44 for uprights 12 and crossbeams 16 of at least one cell 8 (figure3, step A).

[0046] Then any surface treatments of the cheek panels, such as for example varnishing, smoothing and surface finishing 8 figure 3, step B) are performed.

[0047] Then the step of preassembling at least one pair of uprights 12 and one pair of crossbeams 16 each comprising a load-bearing metallic core 32, comprising means of attachment 36 of the external glazing 24, and at least one cheek panel 44 in wood, opposite said means of attachment 36 takes place; the cheek panel 44 is preassembled to the core 32 by means of shaped couplings 60 and/or gluing means 64.

[0048] In particular, first the gluing or sealing agent is distributed in the chamber between the metallic core 32 and the cheek panel 44 and then the panel and the core are assembled by means of the shaped coupling between the protuberance 68 and the groove 72 (figure 3, step C).

[0049] The method may comprise the creation of an assembly kit comprising the metallic cores of the uprights 12 and of the crossbeams 16 preassembled to the respective cheek panels 44 so as to permit subsequent assembly to each other to form a cell to insert in a structural wall 4 ( figure 3, step D).

[0050] The method may rather comprise the step of immediately assembling the crossbeams 16 and the uprights 12 so as to form a structure closed around the perimeter delimiting a perimetral compartment 20 and closing the perimetral compartment 20 by external glazing 24 mechanically associated to the frame on an anterior face 28 of the latter (figure 3, step E).

[0051] For example, the glazing 24 is attached with gluing and structural sealing to a small support frame 40, said small support frame 40 being attached on an anterior face 28 of said metallic core 32 by said means of attachment 36.

[0052] As may be seen from the description, the present invention makes it possible to overcome the drawbacks presented in relation to the prior art.

[0053] In particular, it permits an improvement of the final internal appearance of the facade, while maintaining unaltered the glazed exterior typical of the structural facade, comprising visible external metallic elements.

[0054] Moreover, the present invention permits an improvement of the heat insulation performance for improved comfort of the surroundings.

[0055] Moreover, the present invention permits an improvement of noise reduction, increasing the mass of the joints between adjacent cells.

[0056] Moreover, the presence of the wood cheek permits a considerable improvement of the fire resistance of the cells and therefore of the facade itself.

[0057] The shaped coupling and the gluing of the metallic cores and the cheek panels makes it possible to make the wood collaborate structurally with the aluminium, improving that is to say increasing, the final inertia of the structure. In other words, the coupling of the metallic core and the relative cheek is not of a purely structural type, that is does not guarantee the same rigidity given for example by nuts and bolts which join said elements to each other in a rigid manner. In fact, a structural type connection would create high tension between the two materials having different deformations depending on the environmental conditions of temperature but also of humidity.

[0058] The use of shaped coupling means and gluing means rather allows both different deformations of the elements, without creating excessive tension on the same, and also an increase in the mass and overall inertia of the uprights and the crossbeams, so as to improve the heat and noise insulation of the structure.

[0059] A person skilled in the art may make numerous modifications and variations to the facades described above so as to satisfy contingent and specific requirements, while remaining within the scope of protection of the invention as defined by the following claims.
