DETAILED DESCRIPTION OF THE INVENTION

[0062] The features and advantages of the present invention will be further clarified by the following detailed description of some embodiments of the present invention, presented by way of example and not limitation, with reference to the attached figures.

[0063] It is noted that the figures are not to scale and are for illustrative purposes only.

[0064] In the figures, reference numeral 100 indicates a covering element of a reveal 60 of a fixture compartment, such as for example a window 65, which when installed covers one side of the reveal 60 and at the same time also a portion of the facade (e.g. part of an external face of a masonry structure 31) of a building (as schematically shown in FIGS. 3 and 4).

[0065] The covering element 100 has a main extension direction 200, referred to as the longitudinal direction.

[0066] The covering element 100 comprises a supporting structure made of wood 90 which exemplarily consists of a first 1, a second 2, a third 3 and a fourth panel 4 in series with each other. Exemplarily, the supporting structure 90 has a constant section orthogonal to the main extension direction 200 when moving longitudinally. In other words, the sectional conformation of the supporting structure 90 (i.e., of the panels 1-4) does not vary depending on the longitudinal height of the covering element 100 at which the section is realized (like for example shown in FIGS. 2a and 2b showing two sections respectively on the planes A and B of FIG. 1).

[0067] Each panel 1-4 has a respective main extension plane, i.e. the plane (e.g. vertical in FIG. 1) defined by the two largest dimensions of each panel (typically, length and width). Each panel 1-4 typically has a thickness (i.e., the dimension orthogonal to the respective main extension plane) that is less (e.g., at least twice—for the second and fourth panel, or at least five times—for the third panel, or at least ten times—for the first shorter panel) than both the respective length and width. In FIG. 2a for each panel a dashed line (1′-4′) shows the section of the respective main extension plane (conventionally placed at half thickness). Each panel 1-4 has a respective first face and a respective second face opposite to each other and parallel to the respective main extension plane of the panel.

[0068] Exemplarily, the panels 1-4 have a rectangular shape both seen in plan and in the orthogonal section (FIGS. 2a-b). Exemplarily, the panels 1-4 are OSB panels.

[0069] Below, with reference to the figures and in particular to FIG. 1, the spatial orientation of the panels 1-4 constituting the supporting structure 90 is described.

[0070] The first panel 1 is rigidly connected (e.g. glued and/or fixed by mechanical fastening elements) to the second panel 2 at an end portion of the second panel 2. The latter, in turn, is rigidly connected to the third panel 3, with the third panel 3 being fixed to an end portion of the second panel 2 opposite to the end portion to which the first panel 1 is fixed. Exemplarily, the fourth panel 4 is rigidly connected to the first panel 1 on the opposite side with respect to the second panel 2, with the first panel 1 being fixed to an end portion of the fourth panel 4.

[0071] In the figures it is shown that a respective side edge of the panels 1 and 3 (i.e. the edge corresponding to the thickness) are in contact with end portions of the first face of the second panel 2 (so that there is coplanarity between the side edges—of which only one is shown with the reference number 2″—of the second panel 2 and a respective face of the first 1 and third panel 3—of which only face 3″ of the third panel 3 is shown), and that a respective side edge of the first panel 1 opposite to the second panel 2 is in contact with an end portion of the first face of the fourth panel 4 (respecting the aforesaid coplanarity). In any case, the present invention also contemplates embodiments in which the respective side edge of the second 2 and/or of the fourth panel 4 are in contact with end portions of the respective faces of the first 1 and/or third panel 3.

[0072] The main extension planes of contiguous panels in the series are perpendicular to each other, therefore the main extension planes of the first 1 and third panel 3 are parallel to each other and perpendicular to the extension planes of the second 2 and fourth panel 4, the latter being in turn parallel to each other.

[0073] The first 1 and third panel 3 extend on the same side of the second panel 2, or in other words, the respective main extension planes of the first 1 and third panel 3 have a same extension direction (i.e., spatial conformation like a “u” of the sequence formed by the first, second and third panel). The main extension plane of the fourth panel 4 has exemplarily opposite extension direction with respect to an extension direction of the main extension plane of the second panel 2, where the fourth 4 and second panel 2 extend at opposite edges of the first panel 1 (i.e., spatial conformation like a “z” of the sequence formed by the fourth, first and second panel).

[0074] The aforesaid arrangement of the panels 1-4 causes a pocket 91 to be formed between the first 1, second 2 and third panel 3, i.e. a space confined on three sides that extends along the entire longitudinal length of the covering element 100. For example, said pocket 91 is defined by the respective first faces of the first 1, second 2 and third panel 3.

[0075] A portion of the first face of the first panel 1, the first face (for the part left free by the first and third panel) of the second panel 2 and the first (whole) face of the third panel 3 define the pocket 91. Conversely, the remaining portion 1″ of the first face of the first panel 1 is free from the pocket 91. In other words, with reference to a direction perpendicular to the main extension plane of the second panel 2 (i.e. a direction parallel to the extension plane of the first and third panel), the third panel 3 has dimension (e.g., extension) smaller than the dimension (e.g., extension) of the first panel 1.

[0076] The covering element 100 comprises a filling assembly 5 housed in the pocket 91. Exemplarily, the filling assembly 5 occupies entirely the three-dimensional space defined by the pocket 91. For example, to stably fix the filling assembly 5 to the pocket 91, a respective adhesive layer (e.g. a glue) is provided between the first faces of the first 1, second 2, and third panel 3 and the three faces of the filling assembly 5 that contact the aforesaid first faces (in other words the filling assembly 5 is glued to the inner surface of the pocket 91).

[0077] Exemplarily, the filling assembly 5 comprises an insulating element 7 (in the example of FIG. 1 two distinct portions 7′ and 7″ of the insulating element are shown) made of insulating material, for example EPS reinforced with graphite.

[0078] Exemplarily, the filling assembly 5 also comprises at least one anchoring element 6, exemplarily made of wood and as a single piece. For example, the anchoring element 6 is a solid wood block. In FIG. 1, a single anchoring element is shown for simplicity of representation, however the covering element of the present invention more typically comprises more than one anchoring element housed in the pocket and longitudinally spaced apart from each other. Exemplarily, the anchoring element 6 has a longitudinal length equal to about 15 cm.

[0079] The insulating element 7 exemplarily extends overall for about 70% of the longitudinal length of the covering element 100, the remaining part being filled by the one or more anchoring elements 6.

[0080] The longitudinal dimension at which the anchoring element(s) 6 is positioned is dependent on the specific needs of the construction site in which the covering element 100 is installed, as better explained below.

[0081] Exemplarily, the covering element 100 comprises a fastening element 10 (or more typically a plurality of fastening elements) fixed to the second face of the third panel (i.e. the face of the third panel opposite to the first face defining the pocket 91). Typically, for each fastening element 10 there is a respective anchoring element 6.

[0082] Exemplarily (and typically), the fastening element 10 is fixed to the anchoring element 6, for example by means of mechanical fastening means 70 (e.g., a threaded screw) that cross the thickness of the third panel 3 and enter the anchoring element 6 (as schematically shown in FIG. 2b).

[0083] The fastening element 10 is for example a metal corner plate configured to fix the covering element 100 to a facade of the building (as schematically shown in FIG. 3).

[0084] The covering element 100 comprises a layer 9 made of insulating material, exemplarily XPS, which continuously covers the second face of the first 1 and second panel 2 (i.e. the faces of the two panels opposite to the respective first faces defining the pocket 91). Exemplarily, the layer 9 also continuously covers a first face of the fourth panel 4. In other words (as schematically shown in FIGS. 1 and 2a-b), the layer 9 has a thickness such as to be flush with the side edge of the fourth panel 4. The layer 9 can for example be fixed to the respective faces of the fourth 4, first 1 and second panel 2 by gluing.

[0085] Exemplarily, the fourth panel 4 comprises a recess 92 (shown in an accentuated manner for illustrative purposes) at a second face of the fourth panel 4 opposite to the first face of the fourth panel 4. Exemplarily, the recess 92 has minor surface extension of the second face of the fourth panel 4, and typically extends starting from the end portion of the second face of the fourth panel on the opposite side to where the coupling between fourth 4 and first panel 1 takes place.

[0086] Exemplarily, the covering element 100 comprises a support body 14 which exemplarily extends (as a single piece) over the entire longitudinal length of the covering element 100.

[0087] Exemplarily, the support body 14 comprises a first portion 14′ housed, in part, in the recess 92 and a second portion 14″ contiguous to the first portion 14′ and in contact with one face 40 of the layer 9 opposite to the first panel 1 (see FIG. 2a). For example, the support body 14 can be coupled to the covering element 100 by gluing the first portion 14 to the second face of the fourth panel 4 at the recess 92.

[0088] Exemplarily, the covering element 100 comprises (as shown in FIGS. 2a-b and 3) a levelling aid device, for example a net 51 fixed to the second portion 14″ of the support body 14.

[0089] As shown in the figures, the first portion 14′ of the support body 14 protrudes in the extension plane of the fourth panel beyond the recess 92 and the second portion 14″ to give a reference for the thickness of the levelling.

[0090] Advantageously, the covering element 100 described above is realized as a prefabricated element in a remote production site, and subsequently transported to an installation site, i.e. the site, for example a construction site, where the reveal 60 to be covered is present.

[0091] Typically, at the remote production site a covering system 150 of a reveal which comprises three, or exemplarily four, covering elements of the type described above is realized as a prefabricated. The covering system consisting of three covering elements provides that the three covering elements are fixed together in series to form a “U”. In other words, the respective main extension directions of the three covering elements lie in a same plane (i.e. are co-planar) and the main extension direction of the central element is perpendicular to the main extension directions of the terminal elements, with the terminal elements extending on a same side of the central element. In the case, for example, of a reveal of a rectangular compartment for window, the aforesaid covering system is then configured to cover the upper (horizontal) side of the reveal and the two lateral (vertical) sides of the reveal. In case the covering system comprises four covering elements, the fourth element is arranged in such a way as to close the profile defined by the other three elements, thus realizing a covering system also for the fourth side of the reveal (e.g., the horizontal lower side).

[0092] The Applicant has realized that, during production, it is possible to adapt each covering element 100 of the covering system 150 to the particular needs of the reveal to be covered and/or the conditions of the facade portion to be covered. For example it is possible to modify the dimensions of the covering elements of the covering system 150 according to the needs of the work site, and in particular by adjusting: i) the longitudinal length of each covering element 100, as a function of the height/width of the reveal, ii) the dimension (along the direction perpendicular to the extension plane of the second panel) of the portion 1″ of the first panel 1 free from the pocket 91, as a function of the depth of the portion of reveal left free by the window, with respect to the external facade of the building, iii) the dimension (along the direction perpendicular to the extension plane of the second panel) of the first 1 and third panel 3, as a function of the thickness of the thermal coat of the building.

[0093] The covering system 150 is fixed to the wall 31 of the building facade by taking advantage of the fastening elements 10, for example through one or more respective mechanical fastening elements 72 (e.g., threaded screws). In this way, the reveal 60 of the compartment of the window 65 is covered in a simple manner.

[0094] An airtight element 50 (e.g., a self-expanding adhesive) may be exemplarily coupled (e.g., by gluing) to the covering element 100. Said element 50 is for example glued to the first portion 14′ of the support body 14 on the opposite side to the second face of the fourth panel 4.

[0095] As shown in FIG. 3, once the covering system 150 is installed, one or more covering elements 100 are fixed to one or more support elements 95 for one or more respective accessory devices to the fixture, such as for example one or more hinges per roller shutter (not shown).

[0096] The support element 95 is fixed (for example by means of a suitable threaded screw 71 integral to the support element) to the second panel 2 so as to protrude from a free face 41 of the layer 9 parallel to the extension plane of the second panel 2. Exemplarily, as schematically shown, the fastening means 71 of each support element 95 crosses (perpendicularly) the second panel 2 and is fixed to the respective anchoring element 6.

[0097] In one embodiment not shown, the covering system may comprise one or more covering elements in which the filling assembly consists solely of the insulating element (i.e., it is devoid of the one or more anchoring elements), which entirely fills the respective pocket of the covering element. In this way the covering element has high thermal insulating properties. Such an embodiment turns out to be advantageous when said covering element covers a side of the reveal having a limited length, such as for example the upper and/or lower sides of a reveal. In fact, in this case, for the stable fastening of the covering system it is sufficient to provide fastening elements only at the covering elements that cover the long sides of the reveal (e.g., the vertical lateral sides). Furthermore, it is possible to anchor support elements to such a covering element, typically which do not have to bear high loads, such as for example a roller shutter-stopper, or, as schematically shown in FIG. 4, a plate 95′ for a balustrade, by means of for example a screw engaging the first panel 1 (entirely traversed) and third panel 3.

[0098] Once the reveal 60 has been covered (and the one or more support elements 95, 95′ fixed), a levelling operation (i.e. the application of a layer 68, for example of slaked lime) can be carried out at the free surface of the layer 9 (i.e. the entire surface of the layer 9 on the opposite side to the second faces of the first and second panels), in continuity with the levelling of the cover 32.
