Description

MODULE AND MODULAR STRUCTURE FOR MAKING THE FLOOR OF A
RAILWAY COACH
Field of the invention
The present invention relates in particular to the field of railway coaches. In particular, the invention relates to a module for making the floor of a railway coach, the module being provided with at least one electric heating element.
Background art
The floor of railway coaches is generally made by panels with a substantially rectangular shape.
An example of a floor made by modules according to the background art is shown in Fig. 1 .
In the background art, the panels are designed to be arranged longitudinally, i.e. , with the longest side of the panels arranged parallel to the longitudinal axis of the coach. Typically, the panels are arranged so as to form three rows of panels adjacent to each other. In particular, a central row of panels is arranged between two lateral rows of panels, as shown in Fig. 1 .
Disadvantageously, to date, the assembly of the panels for making the floor is an operation that requires a lot of time, typically a working day.
In particular, the panels must be arranged on a structure, or sub-structure, so that the panels are raised. Therefore, disadvantageously, the elements forming the substructure must first be arranged and then the panels are arranged on the substructure and are fastened thereto.
Furthermore, disadvantageously, in the background art the levelling and alignment operations of the panels are not easy.
It can also be necessary to have access to electric cables arranged below the panels. To have access to the electric cables, to date at least one panel must be removed.
Disadvantageously, the removal of a panel is particularly complex, in particular because the joints between panels are grouted. Furthermore, it is not always possible to remove a single panel, without having to remove others as well. In fact, to remove a panel from the center row, the panels adjacent thereto must also be removed.
Therefore, the need to overcome the limits of the background art is felt.
In particular, the need is felt to reduce the assembly time for making the floor of a railway coach.
The need is further felt to allow a panel to be removed more easily, for example to be able to perform maintenance operations.
EP2409890 describes a system for making a floor according to the background art. Such a system is disadvantageous, in particular because it necessarily requires a rail with a very complex double "C" geometry created ad hoc, the rail having two long longitudinal slits; the system of EP2409890 is disadvantageous also because it requires very long sliding blocks inserted in the rail, of which at least one must necessarily be inserted in the rail on site, while the floor is being made. It is therefore not possible to make a pre-assembled component which is sufficiently advantageous.
Summary of the invention
It is an object of the present invention to simplify and speed up the creation of the floor of a railway coach.
It is another object of the present invention to make it easier to remove the panels with which the floor of the railway coach is made, so as to simplify maintenance operations.
The present invention achieves at least one of such objects, and other objects that will become apparent in the light of the present description, by means of a module according to claim 1 for making the floor of a railway coach, the module comprising a panel, provided with at least one electric heating element, the panel having an upper surface destined to be the upper surface of the module when it is installed; a first lateral portion, extending laterally with respect to the panel, along a first side of the panel, provided with a plurality of holes; a second lateral portion, extending laterally with respect to the panel, along a second side of the panel opposite said first side, provided with a plurality of holes; wherein the module further comprises a crosspiece, constrained to the first lateral portion; wherein said crosspiece is arranged partly below said first lateral portion and protrudes laterally with respect to said first lateral portion, in particular so as to define a support surface in particular for the second lateral portion of another module; wherein the crosspiece is provided with a first set of holes, or first holes; wherein the crosspiece is constrained to the first lateral portion by means of first screws, each first screw being arranged in a respective hole of the first lateral portion and in a respective hole of the first set of holes of the crosspiece; and wherein the crosspiece is provided with a second set of holes, or second holes, adapted to allow fastening to the crosspiece by means of second screws of the second lateral portion of another module; said holes of the first set of holes and of the second set of holes of the crosspiece being in particular made in said support surface.
The invention further relates to a system for making the floor of a railway coach, according to claim 10.
The invention further relates to a structure for making the floor of a railway coach, according to claim 14.
The invention further relates to a railway coach according to claim 17.
The invention further relates to a process for making the floor of a railway coach, according to claim 18.
Advantageously, the modules according to the invention allow making the floor of a railway coach quickly, in a much shorter time with respect to that used with panels according to the background art.
In particular, the crosspiece of each module, already constrained to the respective panel, serves to form the structure, or sub-structure, with respect to which the panels are raised.
