    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention relates to a system to facilitate the bonding and reinforcement of plastic covers of greenhouses, whose obvious purpose is to join and provide for breakages in the plastic covers of greenhouses, in order to offer an optimal fastening of the plastic sheet of a greenhouse without deterioration of it at the time of carrying out its fixation.
    [0007]
    [0008] It is also the object of the invention to ensure that the friction caused by the metal parts of a greenhouse can be foreseen when it rubs against the plastic sheet of the roof, either by adhering to the plastic sheet of the roof or adapting to the shape of the element metallic that produces the breakdown in the plastic sheet of the greenhouse cover.
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] Generally, a greenhouse is a device used for cultivation and protection of plants and crops, which optimizes solar radiation under controlled conditions and improves crops, making it possible for farmers to work.
    [0013]
    [0014] The greenhouse is the most important element of agricultural exploitation and on which production depends largely, constituting in turn the element that makes agricultural production independent of meteorological changes.
    [0015]
    [0016] Several types of greenhouses are known based on metal structures, forming tunnels (multi-tunnel), and others formed by metal posts and roofs composed of a sandwich of wire and plastic, and tension wires (tensile structures).
    [0017] Now, the greenhouses that are most used are those called "scraped and dipped", representing this type of greenhouses 90% of those that currently exist in, for example, Almeria, which is the area with the highest concentration of greenhouses in the world .
    [0018]
    [0019] In this sense, it is called "scrape" at the maximum height of the greenhouse, and "drowned" at the lowest.
    [0020]
    [0021] In any case, the greenhouse cover is formed by a sandwich consisting of two layers of woven sweet wire forming squares, located at the top and bottom, and between them a plastic sheet, which forms a set with the two layers of wire and that is very resistant to wind blows.
    [0022]
    [0023] The two layers or wire frames next to the plastic sheet that form the greenhouse cover, join together with a few points of wire through and tearing the plastic sheet, causing it to lose its tightness and causing diseases in agricultural production .
    [0024]
    [0025] In order to alleviate the aforementioned problem, a putty is usually used roughly in the breakage of the plastic sheet that forms the cover of the greenhouse, trying to mitigate such failure without getting its full repair, since not all the leaks of rainwater, mitigating part of the problem, since the putty eventually spoils and falls, leaving the problem unresolved.
    [0026]
    [0027] DESCRIPTION OF THE INVENTION
    [0028]
    [0029] The system for the union and reinforcement of plastic covers of greenhouses that is recommended solves in a completely satisfactory way the problem previously exposed, based on a simple but effective solution, since it not only allows to effectively fix the plastic sheet of the roof to the upper and lower frameworks of the sandwich, but also provides for friction caused by the erosion of the metal structure of the greenhouse with the plastic of the roof caused by the action of the wind, as well as by deficiencies in its assembly, so that by system of invention is achieved a perfect fixation of the plastic sheet of the cover to the metal structure, based on wires that adapt to the geometry of the cover in question, due to its great flexibility.
    [0030]
    [0031] Specifically, according to the invention, the joining or fixing of the plastic sheet between the two layers of woven sweet wire, forming squares, is carried out without having to go through or tear the plastic sheet itself, with wire joints between the frameworks. of upper and lower wire.
    [0032]
    [0033] To do this, on one side of the sandwich structure, the set of participating elements adhere to the plastic sheet, and, on the other hand, it is connected with wire to the upper and lower wire mesh of the plastic sheet .
    [0034]
    [0035] Likewise, the set of elements of the invention can also be used to provide for the friction caused by the metal parts of the greenhouse, when they rub against the plastic of the cover, since the set of elements of the invention adheres on one of its sides to the greenhouse sheet and on the other it acts as a shield, rubbing against the metal part of the greenhouse.
    [0036]
    [0037] In addition, due to the great flexibility of the elements that participate in the system of the invention, they can be adapted and held on one of their sides by means of wires to the shape of the metallic element that causes the breakdown, and on the other of their sides make shield and cushion the friction with the plastic sheet of the cover.
    [0038]
    [0039] More specifically, the invention is based on the fact that on either side of the plastic sheet of the roof, and between it and the respective layers of wire or wire mesh forming the sandwich, a structure formed by a piece of flexible and transparent plastic material, forming a mono-block body with a piece of woven metal fabric with galvanized metal wires, whose perimeter edge is provided with a fold, with the particularity that the piece of flexible and transparent plastic material incorporates a outer adhesive layer protected by a sheet of paraffin paper or disposable silicone, through which, that is, through said layer of adhesive is fixed to the plastic sheet of the cover, while on the other hand the structure it is fixed by wires to the respective layer of woven sweet wire of the sandwich, or what is the same as the wire mesh defined in the overall structure of the greenhouse cover.
    [0040]
    [0041] The structure that forms each set of elements located on either side of the plastic sheet of the cover, can be of circular contour, in which case the piece of metal fabric will include a central protuberance, through which it is fixed by wires to the layers of woven sweet metallic fabric of the cover sandwich.
    [0042]
    [0043] On the other hand, the structure that forms each set of elements located on either side of the roof sheet, can be rectangular in shape, in which case it is complemented with a supplement that improves contact with the metal part of the greenhouse.
    [0044]
    [0045] Another novel feature of the invention is that on the folds of the rectangular contour defined above, and corresponding to the metal piece of fabric, it is hugged with galvanized metal wires, arranged on both sides of the metal piece itself, forming several handles that pass through some gaps of the piece of wire itself.
    [0046]
    [0047] Finally, it should be noted that additionally it has been provided that the set of elements is complemented with galvanized metal wires for fixing the metal structure to any metal part of the greenhouse, whatever the geometry of the outer perimeter thereof.
    [0048]
    [0049] DESCRIPTION OF THE DRAWINGS
    [0050]
    [0051] To complement the description that will then be 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:
    [0052]
    [0053] Figure 1 shows a plan view of a first embodiment of a element used to join and prevent breakage in the plastic sheet of a greenhouse, an embodiment in which the assembly is circular contour, all in accordance with the object of the present invention.

    [0058]
    [0059] Figure 4.- Shows a side view of the assembly represented in the previous figure.
    [0060]
    [0061] Figure 5.- Shows a plan view of a variant embodiment of the variant of Figures 3 and 4, in this case with a galvanized metal wire that determines lateral handles for fixing to the metal structure of the framework.
    [0062]
    [0063] Figures 6 and 7.- They show each side and front view of the device of figure 5.
    [0064]
    [0065] Figure 8 shows a detail of how the devices corresponding to the variant shown in Figures 1 and 2 are installed to the plastic sheet of the greenhouse.
    [0066]
    [0067] Figures 9, 10 and 11.- They show different views of how to adapt the set of elements of the invention to different metal parts with different geometries, common in the general structure of a greenhouse, such as a square, circular section profile or in double "T".
    [0068]
    [0069] PREFERRED EMBODIMENT OF THE INVENTION
    [0070]
    [0071] In view of the figures outlined, and in particular of Figures 1 and 2, where the configuration of the joining system has a circular configuration, comprising a piece of transparent plastic material (1), circular in shape, which melts with a piece formed by a woven metal fabric (2), with galvanized metal wires forming small squares (3).
    [0072] Perimeter, this piece based on metallic cloth (2) has a fold (4) to prevent deformation and that it frays.
    [0073]
    [0074] This second piece is centered on a protuberance (5) that protrudes from the part of transparent plastic material (1), and that is where the piece of circular shape formed by the metallic fabric (2), by means of wires, is attached to the upper or lower layer of greenhouse cover wire. It has four holes (8) that connect the vertical and horizontal geometry of the galvanized metallic wire wires that form the circular piece. These sets of galvanized metal wire strands determine ribs (8 ’), being a fundamental requirement that no wire of galvanized metal wire is split to form the holes (8), so as not to lose its strength.
    [0075]
    [0076] From this structuring, the protuberance (5) has holes (8) for passing fixing wires to the wires (7) of the metal framework of the general structure of the greenhouse cover and whose fixing wires referenced with (9 ) in said figure 8.
    [0077]
    [0078] On the back side, the circular-shaped piece of transparent plastic (1) has an adhesive film (10) protected with a sheet of paraffin or siliconized paper (11) that protrudes perimeter, as shown in Figure 2, so that said sheet of paraffin paper is removable at the time of implantation of the system, discarding it, to carry out the fixation by adhesion of the assembly to one or another face of the plastic sheet (6) of the greenhouse cover.
    [0079]
    [0080] In this way, the metallic framework layers or wires (7) that participate in the sandwich-like structure of the roof are attached to the plastic sheet (6) of the roof without the need to cross and tear the roof, thereby preventing it from being lose tightness, in addition to strengthening the structure.
    [0081]
    [0082] An alternative embodiment is shown in Figures 3 and 4, varying only in that in this case both the piece of plastic material (1) and the piece of woven metal fabric (2) is of rectangular configuration, including the same structural elements already referrals, such as the internal fold (4) to prevent fraying of the metal mesh.
    [0083] In this case, the configuration of the protuberance is not exactly the same, defining a padded reinforcement supplement (12) as an anti-friction element with respect to the metal structure of the cover.
    [0084]
    [0085] In figures 5, 6 and 7, a variant embodiment of the assembly shown in figures 3 and 4 is shown, so that in this case, galvanized metal wire elements (13) are taken over the folds (4), forming several handles (14) on both sides, constituting fasteners to the pieces fig. 9, 10 and 11, all so that said handles (14) pass through the rectangular piece of metal fabric (2) through holes (15) provided in said metal fabric (2).
    [0086]
    [0087] Said handles (14) also allow the device to be adapted to any metal part that participates in the structure of the greenhouse cover, adapting to its exterior shape due to its flexibility.
    [0088]
    [0089] Finally, in figures 9, 10 and 11, it is shown how to adapt to the elements described to join any metal part of a greenhouse, and provide for friction caused by erosion of the metal parts of the structure of the structure itself. greenhouse in contact with the plastic sheet that participates in the roof, when it rubs against it, either due to the force of the wind or due to the deficiency of the assembly, adapting to the geometry of the outer perimeter of the main parts of said structure, subject to said profiles by means of galvanized metal wires (16), either in tubes or metal profiles of circular section (17), as shown in figure 10, either in tubes or profiles of quadrangular section (18), as shown in Figure 9, or in double section profiles "T" (19), as shown in Figure 11, resulting in any case an easy element to put on and take off, with a strong fixation thanks to galvanized metal wires (16) with which they are fixed by knotting.
    [0090]
    [0091] In this way, the assembly has a great flexibility of adaptation, since it can be folded by any part, and can be folded, according to reference (20) of figure 9, as well as in other very different configurations.
