    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention falls within the technical field of coatings or coatings for roofs and roofs, more specifically in those made of metal, and refers in particular to a coating for building roofs made with sheets of light metal materials and with hidden joints.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The use in sheet metal roofing construction decks has been known for a long time, thanks in the first place to its high durability, being longer than the asphalt and plastic fabrics of organic origin and, secondly, to its insulating efficiency, thanks to the impermeability that it provides as it is a non-porous material. It also gives great ease to the design and execution of its meetings.
    [0011]
    [0012] The most used metallic material due to its low cost is steel, especially in the form of sheet metal, although it can only be worked with auxiliary devices such as folding machines or industrial profiling machines. The main problem presented by steel sheets is corrosion, the most commonly used solutions being cold galvanized and plasticized or baked lacquered.
    [0013]
    [0014] On the other hand, any roof, whether flat or inclined, must meet a series of requirements regarding air tightness, thermal comfort, energy accumulation, structural and fire safety and water tightness. In the case of the latter, it is the main cause of deterioration of a roof, including those of sheet metal, so its correct design should take into account different parameters such as the slope of the cloths, the size of the metal sheets , or the means of overlapping and anchoring between them.
    [0015] Metal materials have a high thermal expansion coefficient (greater than stone materials but lower than synthetic materials), so the joints must tolerate corresponding deformations. The plates cannot be welded together like the sheets due to their high coefficient of thermal deformation, so the study of the types of joints between plates is used, arising, among others, the gasket, the overlapping joints, the joints with additional flashing or recessed joint.
    [0016]
    [0017] The recessed joint allows a flat roof image, even with the possibility of being passable according to the metal material chosen for the sheet and the lower insulating material, thanks to the sheets being folded towards an internal omega profile. In other types of solutions this fold of the sheets, towards the inner profile that is sometimes used as a water collection gutter, results in a rather complicated assembly, which has caused this solution to have fallen into some disuse against the sewn or overlapped joints that ensure water tightness even if they do not always leave the desired final image.
    [0018]
    [0019] DESCRIPTION OF THE INVENTION
    [0020]
    [0021] The object of the invention consists of a light coating of construction roofs, scalable and executable on site by non-specialized personnel, which is constituted from the combination of a plurality of construction elements such as rails, guides, insulating materials and metal plates.
    [0022]
    [0023] The guides, preferably metallic and made of galvanized steel or other lightweight metallic material with protection against environmental corrosion, are linked to the rails by mechanical fixation, be they screws or nails, and create rails intended to house the metal termination plates. These guides are formed by the union of standardized shaped profiles, so they are easy to find in the market.
    [0024]
    [0025] Each guide comprises at least one omega profile and an L-profile linked on a wing of the omega profile by means of fixing means, such as rivets, mechanical fastening systems or welding points, avoiding a welding cord that would deform the profiles by the low thickness they present. The omega profile preferably has a section of 40x40 mm and wings of 20 to 50 millimeters It may be of a larger section but as long as it is coincident with the section of the wooden strip and the thickness of the insulation. The thicknesses of the omega profile can vary from 0.6 to 1.5 millimeters, but, given the function they should perform, the ideal is to use the thickness of 0.8 millimeters. The L profile is placed on the wing of the omega profile, preferably 30x20 millimeters in size. The arrangement of the L-shaped profile on the omega profile is such that the larger wing of the L profile is disposed on the wing of the omega profile, and with the smaller wing of the L profile, inside the square section of the Omega profile This minor wing of the L profile must be separated from the wall of the omega profile by at least 10 millimeters.
    [0026]
    [0027] The battens, preferably of wood, are directly linked to the roof slab by means of joining elements such as screws, adhesives or the like. Said rails must have a minimum section of 40x40 millimeters, and it is necessary to consider that said section is compatible with the dimensions of the other elements of the lining. Two batches are arranged for each guide, one on each side of said guide.
    [0028]
    [0029] Between the roof strips there is a plurality of plates of rigid insulating material, of a thickness similar to those of said strips. The function of this insulator is first to fill the gap that remains free between the wooden battens, and that the upper metal plates rest on a flat, smooth, continuous surface and with some resistance that can be stepped on in case of maintenance. This prevents the sheet from denting or sinking slightly or partially. Additionally, this insulator reinforces, on a large surface of the roof, the thermal needs of the immediately inferior living space.
    [0030]
    [0031] On the flat structure formed by the guides, the strips and the plates of insulating material, the plates of light metallic material are arranged, although it is contemplated that said plates may be of any other light material and resistant to environmental corrosion. These plates have folds and mills located on their perimeter edges, which allow their bonding, set to the metal guides. Depending on the position the metal sheet occupies on the roof, the design of said folds and milling of the edges varies, being different in those sheets intended to be bordered with a lateral facing.
    [0032] The coating described in this way is executed once the roof slab is finished and the waterproofing and the corresponding thermal insulation are conveniently resolved according to internal use. It has the main advantage of conforming from prefabricated and low cost products. It also offers a flat finish, with the joints between the metal covering pieces hidden in the construction unit itself. This eliminates overhangs and other emerging elements on the plane that may present obstacles in the rapid evacuation of rainwater.
    [0033]
    [0034] DESCRIPTION OF THE DRAWINGS

    [0036] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

    [0045]
    [0046] PREFERRED EMBODIMENT OF THE INVENTION
    [0047]
    [0048] Next, a detailed explanation of a preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.
    [0049] The lightweight construction roof covering described is made up of a plurality of lower supports (1) directly linked to a roof (2) of a building, and a corresponding plurality of upper metal plates (3), linked to the lower supports (1) for the total covering of both said lower supports (1) and the cover (2) on which they are arranged, thus isolating them from external conditions.
    [0050]
    [0051] Each of the lower supports (1) in turn comprises two wooden battens (4), parallel and spaced slightly from each other, and directly linked to the roof (2) by means of joining elements (30), which in this embodiment Preferred are through screws. In the space between the two strips (4) a corresponding metal guide (5) is inserted, which is formed by the union of an omega profile (6) and two L-profiles (7).
    [0052]
    [0053] As illustrated in Figures 3 and 4, the omega profile (6) has a hollow and essentially square central section (8) from which two lateral wings (9) are symmetrically extended, while each of the L-profiles ( 7) comprises a major wing (10) and a minor wing (11), perpendicular to the major wing (10). The major wing (10) is superimposed on one of the lateral wings (9), while the minor wing (11) is inserted inside the central section (8). Each of the strips (4) is arranged under each of the respective side wings (9) of the omega profile (6).
    [0054]
    [0055] Between two lower supports (1) consecutive, and superimposed on the cover (2), there are insulating elements (13), which in this preferred embodiment are blocks of insulating material, which are flush with the lower supports (1) . The function of said insulating elements (13) is to cover the gaps between the lower supports (1), creating a flat and continuous surface, as well as contributing to the thermal and acoustic insulation of the roof (2).
    [0056]
    [0057] Each of the upper metal plates (3), intended to be exposed to external environmental conditions, comprises a laminar body (14) of essentially polygonal geometry and a thickness of small dimensions, which has lateral perimeter edges (15), an anterior perimeter edge (16) and a posterior perimeter edge (17). Each of the side perimeter edges (15) is finished off in a double lower bend (18), intended to be coupled between the central section (8) and a minor wing (11) of the profiles (6.7) of the lower support (1). The anterior perimeter edge (16) is finished off in a lower flange (19) of dimensions similar to those of the battens (4), while the posterior perimeter edge (17) is culminated in an upper flange (20).
    [0058]
    [0059] In the case of those metal plates (3) intended to be in contact with a vertical wall (21), as illustrated in Figure 4, one of the lateral perimeter edges (15) incorporates a folded sheet (22) upper, intended to overlap and link to said vertical face (21). The metal guide (5) is formed in this case only by an omega profile (6), or profile with similar geometry formed for this case, vertical adjacent to the vertical wall (21) fixed next to the upper flange (20) by means of joining elements (30).
    [0060]
    [0061] The option of additionally incorporating sealing elements (23), such as a silicone plastic cord or the like, is contemplated for covering and closing the joints created between two consecutive metal plates (3) and the central section (8) of the profile omega (6) corresponding to the lower support (1) in which they are inserted.
