  • the present invention concerns the technical field relative to the components for the realization of railway, underground railway and tramway lines in general.
  • the invention refers to an innovative type of assembly on which to arrange the tracks and that includes a foundation, realized on site, and a series of platforms arranged over the underlying foundation in a quick and precise manner. It is also described here the relative assembly method of them.
  • Such a solution presents various technical inconveniences among which, for example, the quick deterioration of the layer of material interposed by means of the infiltrations of rain water just in the lodge hole of the cylinder, which resulted exposed to the various environmental conditions.
  • Another technical inconvenience of such a solution was caused by the need for realizing the cylinders in the casting on site, the whole naturally with a significant procedural complication.
  • the platforms were to be holed with the maximum precision to guarantee the correct distance between wheelbases for the lodging of the pivots. The wrong distance between wheelbases of the holes caused the waste of the platform itself. It is therefore evident that such . a solution is absolutely complex and also expensive.
  • the assembly includes a foundation (2) formed by a casting realized on site, preferably in concrete, and one or more than one platforms (3) arranged above the foundation (2 ) .
  • the platforms can eventually be subjected to longitudinal and transversal pre-compression.
  • a platform having at least one hole (12; 212) has been included passing through the entire of its thickness.
  • the underlying foundation includes one or more than one holes (11; 211) , generally cored at the moment of the installation, which are positioned in such a way as to result inside the area defined by the hole that is below of the platform.
  • the connection between the overhanging platform and foundation takes place in a simple manner through the insertion into the said holes of a simple pivot element (7, 8; 207, 208).
  • the pivot element is therefore configured in such a way as to realize a connection between the foundation and the platform overhanging the foundation.
  • connection system significantly simplifies the production process of the platform and the assembly between the parts.
  • the platform in fact will not have to include a snug as per the background art, but may be realized directly with a passing hole or, eventually, obtained subsequently.
  • the realization of a passing hole in the platform is an extremely simpler operation than the one of realization of a snug with a particular geometry and arranged in a specific position.
  • the pivot element (7, 8; 207, 208) can be fixed in the receiving, hole through the injection of an adhesive fluid (9; 209) at least in the portion of hole (11; 211) cored in the foundation (2).
  • the adhesive fluid can comprise polymeric resins of a base mixed with activating resins and with hardening resins to obtain an efficient polymerization of the mixture.
  • the pivot element can be a pivot (7), preferably in steel, comprising a protective cap (8) arranged on the part exceeding the pivot (7), that is the part that emerges from the foundation, and therefore arranged into the hole (12) of the platform.
  • the protective cap (8) can have such a diameter as to obstruct the hole. (12) of the platform (2) according to a predetermined degree of mechanical interference.
  • the protective cap (8) can be realized separable from the pivot in such a way as to result applicable after the insertion of the pivot (7) itself into the holes in axis.
  • an overall number of eight holes (11, 12) can be included, into which a pivot (7), respectively in each one of them, is lodged.
  • the pivot element (207, 208) can include a head (208) and one or more than one legs (207) exiting from the head (208) .
  • the head can be realized in a castable material, for example cement or concrete, in which the legs (207) result buried, the said legs being pivots (207) preferably in steel.
  • the diameter of the head can, for example, be such as not to pass through the hole 212. In such a manner, it clamps against the platform like a bolt. Alternatively, it can be inserted into the hole of the platform with interference.
  • the diameter of the head (212) can be such as to leave a certain radial clearance with respect to the hole (212) of the platform into which it results inserted.
  • this can be constituted directly by the same material (4), which fills the clearance left free between the head (208) and the lodge hole (212) of it.
  • the material interposed (4) can comprise at choice only one or a combination between:
  • the injection of an adhesive fluid in the cored hole can be further included, in such a way that the pivot element remains fixed in position.
  • FIG. 1 shows a section of the invention in accordance with a first possible embodiment
  • FIG. 2 shows a top view always according to such a first embodiment
  • FIG. 3 shows a section that is effective for all the configurations described in order to show the connection of the tracks overhanging the platforms;

  • FIG. 5 and 6 show respectively a top view and a section in accordance with a second possible embodiment of the invention.
  • Figure 1 shows a section relative to the present invention in accordance with a first possible embodiment.
  • the entire assembly 1 is shown that includes a foundation slab 2 realized through a casting on site preferably of light concrete.
  • a series of platforms 3 realized preferably in reinforced concrete, eventually pre-compressed .
  • Figure 2 shows, for greater clarity, a top view relative to the section of figure 1 to show better the succession of the platforms.
  • a predisposition . of only two platforms 3 arranged in succession has been here shown.
  • the succession of the platforms depends on the length of the railway that wants to be realized and can reguire many platforms in succession.
  • an intermediate setting layer 4 that results interposed between the foundation 2 and the overhanging platforms 3.
  • the intermediate layer can be realized according to different solutions.
  • One of these can comprise, for example, a cement mixture or a base -of polymeric resin.
  • This layer can, alternatively, be substituted or integrated to a small mattress 4 in elastomer whenever it is necessary to reduce the transmission of vibrational phenomena towards the environment external to the line.
  • the intermediate layer is rendered necessary to allow a correct coupling between foundation and platform, recovering all the irregularities of casting of the foundation itself within the actual tolerances admitted for civil works.
  • connection between each overhanging platform 3 and the basement of the foundation 2 is obtained through the application of at least one, preferably a plurality, of elements in the shape of a pivot 7.
  • a receiving hole 11 is cored into which the . element 7 is inserted, in this case constituted by a simple pivot, generally in steel.
  • the overhanging platform 3 is also provided with a hole 12 passing through its entire thickness in such a way that, as shown in section of figure 4, the pivot 7 is inserted into the two holes placed in axis between them (figure 4 shows the axis 16 of the two holes).
  • the passing hole 12 has a greater diameter than the diameter of the pre-chosen pivot 7. In such a manner, it is therefore possible to apply a protective cap 8 of such a diameter as to obstruct with a certain degree of mechanical interference the hole 12.
  • a chemical adhesive 9 of the type of the bi or tri-component polymeric resin is injected to guarantee a stable seal of the pivot within the hole.
  • the choice of the features of the components is linked to the types of aggressive elements present . in the intervention area.
  • this shows the first embodiment described here wherein, for each platform, eight pivots are generally included (that is, eight holes for platform indicated precisely in the figure with number 12) .
  • the holes 13 (in an overall number of one or more than one) are instead placed in different pre- chosen points of the platform to allow through them the injection of the intermediate filling layer 4.
  • connection includes a pivot element (208, 207) formed by a head 208 in concrete in which one or more than one pivots 207 are buried.
  • a type of pivot could also be realized, alternatively, in a single piece in metal, for example steel.
  • the pivot is therefore applied, as already described, into the passing hole 212 of the platform in such a way that its legs 207, formed by the pivots 207 buried in it, are inserted into the receiving holes 211 that are below of the foundation 2.
  • any number of legs 207 can be buried in the head 208 and can be arranged according to different geometries (for example, three legs 207 arranged in a triangle) .
  • the holes 211 that penetrate in. the foundation will therefore be placed in different points in such a way as to result comprised within the area defined by the hole 212 resulting above and in such a way that the said pivot element can therefore be installed correctly.
  • the same chemical solidifier 209 is normally injected to fix the connections within the holes 211.
  • the diameter of the head 208 can be such as to obstruct with interference the hole 212, it is preferred anyway to . leave a certain degree of radial clearance.
  • the resin injected is going to fill the free inter-space between the head 208 and the walls of the hole 212, creating a sort of surrounding filling cushion that helps to maintain stable the tangential connection between platform and foundation, in the same way as the cap of the first embodiment.
  • This solutions is also particularly advantageous since it allows a certain degree of freedom for the assembly as well, allowing corrections of misalignments in a simple way.
  • the top view of figure 5 therefore shows this solutions wherein, generally, an overall number of two pivot elements (208, 207) per platform are enough and are arranged on the longitudinal axis of symmetry of the platform itself.
