DETAILED DESCRIPTION OF THE INVENTION

(8) The object of the invention refers to a modular metal covering for buildings, of the type that are made up of metal sheets (1) which are interconnected successively, one after the other, in relation to supports (2) with characteristics of the embodiment that allow the successive metal sheets (1) to be effectively and reliably fastened, thereby achieving an efficient overlap between them, without the need for holes for fastening elements, guaranteeing a perfect impermeability and security for the covering, in addition to a quick and simple assembly.

(9) Each metal sheet (1) of the covering's composition comprises a flat central surface (3), forming a bend (4) throughout the length of the edge for assembly and to be supported by the supports (2), and forming along the opposite edge a bend (5) to be assembled and fastened to the supports (2), such that both bends (4 and 5) form a lower groove (6) at their beginning, preceded by a small projection (7) with respect to the flat central surface (3) of the metal sheet (1), and from that groove (6) each one of the bends (4 and 5) defines a vertical section that ends at an upper break (8) defined by a slight declination, wherefrom the bend (4) extends upwards with a bowed wing (9) that turns back onto itself until it reaches a horizontal section (10) that ends with a vertical tab (11), while the bend (5) extends from the upper break (8) with a wing (12) that defines a domed shape that ends with an inward-facing tab (13).

(10) Each support (2) comprises a central body (14) in the form of a column, which begins at a lower base formation (15), said central body (14) determining a “T”-shaped structure (16) in its upper end, whose branches define a small nook in the lower face, the end of one of the branches having a vertically curved beveled cut, while at a certain distance below said “T”-shaped structure (16), on the sides of the central body (14), there are grooves (17) that end at a protruding edge (18), said grooves (17) possibly in a “T”-shaped structure (19) configured at an intermediate height of the central body (14), as in the embodiments of FIGS. 1 to 5, or in the structure (15) of the base support (2), as well as in the embodiment of FIGS. 6 and 7.

(11) In the assembly of the covering, the metal sheets (1) are arranged with the bends (4 and 5) of their edges over both rows of support (2), providing support with the horizontal section (10) of the bend (4) of one of the edges over the corresponding supports (2) and fitting with the lower groove (6) and the respective projection (7) in the groove (17) and the respective protruding edge (18) of one side of said supports (2), while the upper break (8) of said bend (4) fits in the nook of the lower face of the branch of that side of the “T”-shaped structure (16) above of the supports (2), as can be seen in FIG. 3.

(12) On the other side, the metal sheets (1) are arranged to fit with the lower groove (6) and the respective projection (7) of its bend (5) of the other edge on the groove (17) and the respective protruding edge (18) of the other side of the corresponding supports (2) and the upper break (8) of said bend (5) fitting in the nook of the lower face of the branch of that side of the “T”-shaped structure (16) above said supports (2), the dome-shaped wing (12) of the aforementioned bend (5) being above the “T”-shaped structure (16) above the supports (2), such that the terminal tab (13) of that dome-shaped wing (12) fits in the edge of the branch of the other side of the mentioned “T”-shaped structure (16) above the supports (2), as can be seen in FIG. 4.

(13) With this arrangement in the assembly, the assembly of two consecutive metal sheets (1) is done on one row of supports (2), with one of the metal sheets (1) with its bend (4) on one side of the supports (2) and the other metal sheet (1) with its bend (5) on the other side of the same supports (2) such that the dome-shaped wing (12) of the bend (5) of the second metal sheet (1) is on top and butting up against the wing (9) and the tab (11) of the upper part of the bend (4) of the first metal sheet (1), as can be seen in FIG. 5.

(14) This way, each one of the metal sheets (1) is individually and securely fastened to the supports (2), thanks to the opposing double fit established by the lower grooves (6) and the upper breaks (8) of the bends (4 and 5) with respect to the metal sheets (1), in relation to the corresponding grooves (17) and the projections of the lower face of the wings of the “T”-shaped structure (16) above the supports (2), as well as the fastening element of the tab (13) of the dome-shaped wing (12) with respect to the aforementioned “T”-shaped structure (16) above the supports (2).

(15) Moreover, between the metal sheets (1) is a perfectly sealed connection due to the upper cover the dome-shaped wing (12) provides above the connection and at the height of upper edge of the bend (4) in the interior of the aforementioned domed-shape wing (12) covering the connection.

(16) The supports (2) may be arranged on a forged platform above the buildings where the cover is to be applied, or directly on the structure of the structural frame of the buildings, with the possibility of using supports (2) with grooves (17) formed in a structure (19) located at an intermediate height of the central body (14), as well as in the embodiment of FIGS. 1 to 5, in this case below the arrangement of the metal sheets (1), in the assembly of the covering, a hole that allows an insulating material to be included.

(17) However, when a layer of an insulating material is not going to be included under the covering, supports (2) at a lower height may be used, with the grooves (17) formed in the lower structure (15) of the base, as in the embodiment of FIGS. 6 and 7.
