Description

FIELD OF INVENTION The present invention relates to a prefabricated modular element for a structure adapted for supporting telecommunications stations. KNOWN PRIOR ART According to known art, telecommunications stations comprise a square or triangular-based lattice, or pole, for supporting the antennas, often exceeding twenty-five meters in height. The lattice, or pole, in turn, is anchored to a foundation structure of reinforced concrete, which is made on-site, with casing and in situ concrete casting. Clearly, the whole structure is sized to withstand the maximum stresses (static, seismic and meteorological) provided by the regulations in force, more precisely, the station is considered "construction" to all purposes, therefore, like any construction, it is subject both to urban rules and regulations and to the constraints imposed on the protection of the territory and public safety. This solution has several drawbacks, indeed, being made in situ, it requires significant commitment of workers and long times, both for the processing and for the foundation concrete curing, which typically takes more than twenty-eight days after casting. Furthermore, it is clear that this structure, being a "permanent construction", has a significant environmental impact. Finally, when it is necessary to remove it, it will be mandatory to arrange for its demolition and disposal of the resulting materials, with definitely significant time and costs. In order to mitigate most of these critical issues, solutions are known providing the construction of a set of precast elements made of reinforced concrete, to be assembled on-site in order to form a base, serving as the foundation for a lattice or a pole. The solution provides that this base or foundation is inserted into excavation dug at the location where said station is installed. The base or foundation is formed by multiple layers of precast reinforced concrete manufactured articles that are superimposed, constrained to each other, through a plurality of removable fastening means, such as, for example, bolts, plates, rods, cables and tie rods, so as to create a kind of "sandwich" coupling. Each superimposed layer is quadrilateral in shape, resulting in a parallelepiped-shaped base. The lattice or pole, along with the telecommunications apparatuses, is constrained to said base by means of appropriate nuts and bolts. In order to adapt the static performance of the bases to lattices or poles of different heights and loads, additional layers of prefabricated manufactured articles are added, or larger manufactured articles are used. The above solutions, however, are not free from drawbacks, since although many of the problems related to the structures made directly on site are overcome, the operation of the base and its stiffness, as it is made, rely exclusively on the nuts and bolts and the consequent friction between the various layers of said "sandwich". Furthermore, these prefabricated structures cannot be transported anywhere, specifically in remote areas that can only be reached by helicopter use. EP4194613A1 is directed to a structural unit and system for manufacturing a concrete foundation, specifically for a beach umbrella. CA2142383A1 concerns the construction sector and specifically the manufacture of vertical concrete poles anchored to the ground. JP2012127050A concerns a concrete foundation to be laid on a floor and a method for manufacturing the concrete foundation. Lastly, ITMC20060023A1 concerns modular equipment for the quick installation of antennas for telephone networks. Therefore, the object of the present invention is to make a modular element for structure for supporting telecommunications stations which, compared to prefabricated solutions of the known art, allows this structure to be implemented in a simple and quick way, regardless of the area where this structure has to be built. Further objects of the present invention are to make a structure that is made up of a limited number of low weight repetitive elements, and therefore, that can be made in a simple, quick, easy-to-assemble way and with a modest investment in precasting molds. Lastly, object of the present invention is to implement a method for making a structure adapted for supporting telecommunications stations, that are easily assembled and transportable. SUMMARY OF THE INVENTION These and other objects are achieved by a modular element for structure adapted for supporting at least one telecommunications station according to claim 1. Specifically, this modular element for structure adapted for supporting a telecommunications station comprises a first lower planar surface and a second upper planar surface opposite and parallel to said first planar surface, said modular element further comprising a metal core embedded, at least partly, in a cementitious structure, said metal core further comprising a perimeter metal structure having polygonal plan and a central metal structure integrally constra
