The present invention places in the technical field related to the implementation of apparatuses for sport venues such as for examples stadia, football pitches, sports halls and/or the like. In particular, the present invention relates to the implementation of stands for sport venues of the type mentioned previously. In detail, the present invention relates to an innovative component or module for the implementation of stands for sport venues or the like.
DESCRIPTION OF THE STATE OF THE ARTIn the field of the implementation of apparatuses for sport venues such as for example stadia, football pitches, sports halls and/or the like, different solutions are known and used. According to the most part of the known solutions, the stands for sport venues of the type mentioned previously are implemented by using pre-fabricated modules in reinforced concrete apt to define so-called big steps whereupon in case seats are then arranged or which simply define surfaces apt to define seating places. Such pre-fabricated modules made of reinforced concrete usually are positioned on a main bearing structure implemented in reinforced concrete too or even in steel or other materials. The bearing structure typically is constituted by columns or vertical walls supporting, in turn, sloped beams thereupon the modules made of reinforced concrete are positioned and fixed. The sloped beams usually are parallel and placed at a distance comprised between 7.50 and 12 m, even if the distance between two adjacent sloped beams is established according to the needs and/or circumstances.
The pre-fabricated modules have a pre-defined shape, in particular a pre-defined cross-section and they are designed and implemented to support both their own weight and the weight of the spectators taking part in an event. Furthermore, the cross-section must be planned to satisfy determined criteria of deformation caused by the vibrations so as to guarantee comfort and safety for the spectators sitting onto the stands. For example, the horizontal portion or “tread” of the big steps can be slightly sloped to ease the draining or outflow of the rain water, as well as to ease cleaning of the stands at the end of an event. Said tread has to be further designed so as to define a space for the seating places (in case for the seats), as well as walkway corridor in front of the seating places or seats. The vertical portion or “riser” of the big steps constitutes the rear or resting portion of the big steps and thereon the brackets for fastening the steps are generally fastened.
The solutions known in the state of art utilizing prefabricated modules made of reinforced concrete have several problems and disadvantages. One first considerable disadvantage is related to the prefabricated modules' own weight which usually corresponds to 400 kg/sm. Such own weight per volume unit requires to implement an adequate supporting structure, with considerable increase in related costs and implementation time. In fact, in case one implements a supporting structure made of reinforced concrete too, adequate seasoning time is to be provided. Furthermore, individual moulds have to be arranged wherein the concrete in the fluid state is cast. Another disadvantage due to the reinforced concrete prefabricated modules' high own weight is related to the difficulty in moving said modules, therefor suitable apparatuses (cranes and trucks with considerable sizes) are necessary involving a considerable and often too high utilization cost. Still by referring to the solutions making use of prefabricated modules made of reinforced concrete, among the additional problems and disadvantages typical of these solutions, the dangers deriving from the implementation of stands of this type in areas with high seismic risk are to be mentioned. Yet still, the modules made of prefabricated reinforced concrete involve additional problems when, on the stands' big steps implemented by means of said modules, additional apparatuses have to be fastened, such as seats, small chairs or the like. In fact, the installation of the seats requires to perforate in advance the modules in predefined positions as well as the use of expansion or chemical stoppers for fastening the seats' supporting plates to the big steps; however, the precision required for defining the perforation sites involves a huge time waste with a corresponding increase in the involved costs. The same is valid for applying the expansion or chemical stoppers in the implemented perforations or holes.
Moreover, solutions for implementing stands for sport venues are known to the state of art, utilizing materials different from concrete, such as for example steel, zinc-coated or painted iron and/or similar materials. For examples, solutions are known making use of components such as tubes, joints, pivots or others wholly similar to those used for implementing scaffoldings. However, these solutions offer neither required safety nor comfort and often they cannot be proposed due to their definitely rough aesthetical aspect. Other solutions making use of steel and/or iron and/or similar metals had not allowed to overcome in a satisfactory way the drawbacks typical of the solutions made of reinforced concrete. Several of these solutions show the same problems in terms of scarce motion easiness, excessive own weight, assembling difficulty and not satisfying final aspect. Among the various known solutions in the state of art making use of components made of steel or iron or similar metals, those described in the documents U.S. Pat. No. 7,047,699, U.S. Pat. No. 5,159,788 and WO2010/028476, US 2006/150540 A1 and G 2 463 445 A can be mentioned.
Therefore, an object of the present invention is to obviate the drawbacks mentioned previously and found in the solutions known in the state of art. In particular, the objects and aims of the present invention can be summarized as follows.
To propose a solution related to a module for the implementation of stands with big steps which has its own reduced weight, which is then easy to handle, which is resistant and able to support suitable loads, which can be implemented in a simplified way and with reduced costs, which is easy to be assembled and that is which can be assembled by means of relatively simple and quick operations and therefore with contained costs, which is easy to be moved (raised, transported, etc.), which has a pleasant aspect compatible with the aesthetical needs of venues of a certain prestige, which offers the adequate guarantees in terms of safety and comfort for the spectators. An additional object of the present invention is then to offer a solution allowing to implement a prefabricated module in metal for implementing stands for sport venues which can be implemented by using traditional materials which can be processed even non-industrially. An additional object of the present invention is to suggest a module with predefined shape and size, which is then interchangeable and usable for implementing stands with different sizes. The module shape according to the present invention will further have to allow constraining mutually two adjacent modules in a simple and quick way and without requiring the use of special and expensive anchoring means. The module will further have to be able to be produced in different formats according to the needs or circumstances and the format change without involving drastic and important changes in the production and/or implementation process.
The objects and aims mentioned and described previously will be achieved by means of a component according to the embodiments claimed in the main claims 1 and 14. Additional advantages will be then offered by the embodiments of the present invention claimed in the depending claims.
DESCRIPTION OF THE PRESENT INVENTIONThe present invention finds particular and advantageous application in the implementation of apparatuses for sport venues such as, for example, stadia, football pitches or the like. In particular, the present invention finds particular and advantageous application in the implementation of stands for venues of the type mentioned previously. For this reason, examples will be described hereinafter wherein the present invention is used for implementing stands for sport venues. However, it is to be noted that the possible applications of the present invention are not limited to the implementation of stands for sport venues. On the contrary, the present invention finds particularly advantageous application in all cases wherein the implementation of a structure with big steps is required, even not assigned to receive public or people. In fact, the present invention allows implementing systems and/or structures with big steps (even not in the sporting field) with low costs, by taking materials available on the market, according to a simplified manufacturing and assembling process and with practically zeroed size and alignment or positioning tolerances.
The present invention bases upon the general concept that the disadvantages or drawbacks typical of the known solutions in the art (in particular the prefabricated modules made of reinforced concrete) can be overcome or at least minimized by implementing a component comprising at least a main module apt to be placed upon a bearing structure to as to implement a portion of a big step, said main module having L and Z-like cross-section and thus comprising a first tread portion defining a substantially flat surface and apt to be stepped on and a second riser portion comprising a flat surface and extending from said tread portion and defining with said tread portion a predefined angle, said main module comprising an upper foil or plate and a lower foil or plate, both made of metallic sheet and shaped like a L and mutually joined so as to define said tread and riser portions, each one of said tread and riser portions comprising an inner space comprised between corresponding portions of said upper and lower foils or plates.
An additional consideration whereupon the present invention is based is related to the fact that additional advantages could be obtained by arranging connecting metallic members in said inner spaces so as to connect mutually said upper and lower plate and/or filling up at least partially with a polyurethane foam said inner space and/or if said main module comprises a first engagement portion of male type and a second engagement portion of female type apt to house an engagement portion of male type and/or if said engagement portion of male type extends from the free end of said first riser portion opposite to said tread portion and said engagement portion of female type is obtained in an end portion of said tread portion opposite to said riser portion and/or when said first engagement portion extends from a portion of metallic sheet of said riser portion joining said lower and upper plates and/or when said second engagement portion of female type is defined by a lowering of said lower plate obtained near the free end of said tread portion opposite to said riser portion and/or when said main module comprises metallic reinforcing members applied to said upper and lower plates, respectively, at the opposite end portions of said main module and placed inside the inner space of said tread portion and/or when two first metallic reinforcing members are connected to said lower and upper plates, respectively, at the first end portion of said main module and two second metallic reinforcing members are connected to said lower and upper plates, respectively, at the second end portion of said main module opposite to said first end portion and/or when said first metallic reinforcing members are mutually connected therebetween by means of cross steel members, and/or when said second reinforcing metallic members are mutually connected one to another by means of steel cross members and/or by using a first infilling stopper inserted at least partially between said upper and lower plates so as to infill a first end portion of said main module and/or a second infilling stopper inserted at least partially between said upper and lower plates so as to infill a second end portion of said main module opposite to said first end portion, so as to prevent rain water infiltrations or the like inside said inner space and/or when said first and second infilling stoppers comprise, each one, a portion localized outside said inner space of said main module and/or when said first and second infilling stoppers comprise, each one, a cross lowering obtained in said outer portion.
The present invention bases upon the additional general concept that the disadvantages or drawbacks typical of the solutions known in the art (in particular of the prefabricated modules made of reinforced concrete or even metallic material) can be overcome or at least minimized by implementing a component comprising at least a main module apt to be placed onto a bearing structure so as to implement a big step portion of said stand, said main module having substantially Z-like cross section and thus comprising a first tread portion defining a substantially flat surface apt to be stepped on by the spectators, as well as a first riser portion and a second riser portion, both comprising a substantially flat surface and extending from opposite ends of said tread portion so as to define, each one, with said tread portion a pre-defined angle, said main module comprising an upper plate and a lower plate, both made of metallic sheet and with substantially Z-shape wherein said upper and lower foils are mutually joined so as to define said tread and riser portions, said tread and riser portions comprising, each one, a corresponding inner space comprised between corresponding portions of said upper and lower foils or plates.
