Definitions

  • the present invention relates to the technical field of products to be used in urban areas or as accessories for public works such as railways, underground lines and their stations, roads, bridges and overpasses. BACKGROUND ART
  • the pavements are part of the project and are built in place, together with the building, road, rail and similar construction.
  • pavements are provided with suitable parapets, for example on bridges, flyovers or overhead passages in general, where the pedestrians risk plunging into the void or at least into a precipice or ditch.
  • railway tracks are usually positioned above a roadbed that serves both to provide a solid support base that is as levelled as possible and to raise from the surrounding ground the level at which the trains pass, making the latter safer with respect to what can happen at ground level as a result of weather events, flooding, overflowing and the like.
  • On-board staff may also have to get off and walk along the tracks, for example due to train breakdown or in the presence of obstacles on the tracks.
  • Another object of the invention is to propose a pavement that can be installed easily and quickly, without the need to build structures dedicated thereto.
  • a further object of the invention is to propose a prefabricated construction of the pavement already provided with at least one side parapet, integral with the base of each module intended to form a part of the walking surface, said parapet having height and strength in line with the imposed standards.
  • a still further object of the invention is to propose a pavement provided with a channelling, passing below the walking surface and designed to house electrical cables and/or various pipes, normally closed outside but accessible through trap doors.
  • a yet further object of the invention is to equip the side parapet with foot stopping walls, in accordance with the regulations that lay them down for certain possible uses of the proposed pavement.
  • a still further object of the invention concerns the desire to obtain modules for said pavement that can be realized with low production costs.
  • a protected functional pavement made of a plurality of modules, mutually combined in a longitudinal direction and placed on a ground or structure horizontally levelled, at least transversally to the pavement itself, with each of these modules including:
  • - Fig. 1 is a side view of a portion of the functional pavement under discussion, in a preferred embodiment
  • Fig. 2 is a plan view of Fig. 1 ;
  • - Fig. 3 is a cross-section of the pavement, along the plane MI NI of Fig. 1 ;
  • Fig. 4 is a view similar to Fig. 3, of a different embodiment.
  • the reference number 100 indicates the protected functional pavement proposed by the present invention, as a whole.
  • the protected functional pavement 100 is formed by a plurality of modules 1 , mutually combined in the longitudinal direction and arranged on a ground S or a horizontally levelled structure, at least transversal to the pavement 100.
  • the above levelling for uneven ground is carried out in a known manner, for example with a bed of suitable filler material R, such as stabilized gravel or similar, which ensures sufficient stability.
  • Every module 1 includes a box-like pavement element 2, whose lower horizontal side 2B is aimed at abutting on said ground S or structure and whose upper horizontal side 2A defines a corresponding portion of the walking surface 10 of said protected functional pavement 1.
  • the walking surface 10 is rough, which makes it anti-skid in the presence of water and prevents the formation of a smooth slab of ice, where weather conditions may cause it.
  • said box-like pavement element 2 is made of prestressed reinforced concrete; in another not illustrated embodiment, the box-like pavement element 2 is made of cast metal, for example cast iron, which gives a sufficient weight and is very resistant to oxidation.
  • the box-like pavement element 2 is provided with at least one through longitudinal channelling 12, arranged in an intermediate position between said lower side 2B and upper side 2A.
  • the through longitudinal channelling 12 connects with the corresponding canalizations 12 of the previous and next modules 1 and thus is continuous for the whole length of the protected functional pavement 100 and allows to receive electric cables and/or pipes for fluids.
  • the through longitudinal channelling 12 shown in the figures is closed at the top by tiles 13 arranged in series, resting on longitudinal edges 12B shaped by the profile of the canalization 12, so that the continuity of the walking surface 10 is restored. Therefore, each tile 13 forms an opening trap door to allow access to the underlying through longitudinal channelling 12.
  • the box-like pavement element 2 can have a substantially tubular cross-section, with the through longitudinal channelling 12 having a closed profile on all sides, except where at least one of said opening trap doors is located.
  • Fig. 3 shows, by way of example, a longitudinally split channelling 12, for example to allow the physical passage of high- voltage and low-voltage cables, or of electric cables and communication lines, or of electric cables and pipes, etc.
  • the channelling can be single in applications in which the splitting is not necessary or advisable.
  • Fig. 4 shows the variant according to which the box-like pavement element 2 is not provided with said through longitudinal channelling 12.
  • a lighting system Inside the channelling 12 is moreover optionally mounted a lighting system, fit to easy the installation and maintenance of cables or piping under limited visibility conditions.
  • Coupling means 3 for example interlocking, are provided in the front end 21 and rear end 22 of said box-like pavement element 2, to couple with the coupling means 3 of a corresponding precedent module 1 and with those of a subsequent module, so as to stabilize said modular pavement 100 both in the longitudinal and transverse directions.
  • the above mentioned coupling means 3 may also be composed of simple complementary protrusions made in the box-like pavement element 2, or consecutive elements may be bolted together, either directly or by means of fixing plates. According to other construction variants, consecutive elements 2 can be arranged simply lying one against another, and the above mentioned coupling means 3 can have other forms, as will be described below.
  • the module 1 is fitted with at least one side parapet 4, the longitudinal length of which is equal to that of the box-like pavement element 2, and made integral with the latter at its base.
  • the parapet 4 extends upwards for a predetermined minimum height, sufficient to contain the body of a person to prevent him/her from falling below. As an indication, this height is at least one metre, as established by the regulations.
  • the parapet 4 is formed by two uprights 40 made of metallic section members, for example an IPE beam, rigidly connected, at their base, to the element pavement box 2.
  • the uprights 40 can also be made of another type of material, provided that it has suitable mechanical characteristics.
  • each module 1 of pavement may be more or less than two, depending on particular needs.
  • only one upright 2 can be provided.
  • the structure of the module including two 40 uprights will be described.
  • the uprights 40 are inserted, with their lower end portion 40B, into corresponding seats 20 provided in the box-like pavement element 2, and are made integral with the latter by a subsequent casting, into the interstices between the end portions 40B and the aforesaid seats 20, of fast solidifying fastening material.
  • the aforementioned fastening material can be cement mortar, whereas if said element 2 is made of cast iron, the fastening material can be epoxy adhesive or equivalent.
  • the uprights 40 can be fastened to the box-like pavement element 2, no matter how it is built, by a perforated anchor plate, not shown, provided at the base of each of them, designed to be blocked to the aforementioned box-like pavement element 2 by means of screws or expansion plugs.
  • a substantially vertical protection 41 integral with the uprights 40, extends downwards starting from said predetermined height level of the parapet 4.
  • Said protection 41 can be made in many variants; in the example shown in the enclosed figures, it is composed of a plurality of horizontal bar elements 42 made of metal, preferably of tubular shape, arranged at different heights.
  • the protection 41 is formed by a panel structure made, at least partially, of metal, for example vertical laths, or a solid or perforated sheet metal.
  • the protection 41 is formed by a panel structure with wire mesh.
  • said panel structure can include a safety glass sheet of adequate thickness.
  • the protections 41 of two consecutive pavement elements 2 are fixed one to another according to techniques that depend on their structure, for example by bolting or other means, in any case, of immediate implementation for the person skilled in the field.
  • the mutual fixing of the protections 41 can also act as a coupling device 3 of the whole pavement element 2 and the subsequent one, if these elements are arranged in succession leaning one against another.
  • the parapet 4 shown in the figures includes a vertical foot stopping wall 44, provided from the upper horizontal side 2A of the box like pavement element 2, or from the walking surface 10, extending upwards with a predetermined height and having longitudinal extension equal to that of the box-like pavement element 2.
  • the vertical foot stopping wall 44 is necessary in environments where occupational safety regulations apply: actually, the protected functional pavement 100, in the illustrated embodiment, is particularly suitable for being placed beside a roadbed M on which the tracks of the railway lines are located.
  • the protected functional pavement 100 can include two parapets 4, on both sides of the walking surface 10 with or without the foot stopping walls 44.
  • heating means are provided inside each box-like pavement element 2 to raise the temperature of the walking surface 10 or parts thereof.
  • heating means are advantageously installed inside the box-like pavement element 2, preferably just below the horizontal side 2a of the pavement element, which is a part of the walking surface 10.
  • the heating means can be provided inside the through longitudinal channelling 12. If more than one channelling are provided, they may also be installed inside all or some of the aforesaid channelling 12.
  • Check and control means are provided to activate the heating means after a minimum threshold temperature has been reached, for example the temperature below which a coat of ice tends to form on the walking surface 10, i.e. about zero degrees centigrade.
  • the heating means are electric and include one or more resistive heaters, suitably connected to each other and to an electrical system specifically designed to power them, through sockets and safety plugs of known type.
  • the heating means are formed by the heat exchanging circulating fluid. Consequently, they are made up of pipes, suitably equipped with hydraulic inlet and outlet connectors to connect the various 1 modules close to each other, inside which the aforementioned heat exchanging fluid can circulate.
  • the fluid may consist of water or other compounds, for example containing antifreeze substances.
  • a thermal power station equipped with a heat generator and delivery pumps to make the heat exchanging fluid circulate between the generator and pipes.
  • the advantageous function of the above mentioned heating means is to clear the walking surface from snow or ice, which can be dangerous for the users safety and is particularly advantageous in installations of the protected functional pavement according to the invention in sites with harsh climate, at least in the coldest period of the year.
  • the protected functional pavement 100 of the invention comprises, for its whole or partial extension, a safety life line, or at least a set of components necessary to set a fall arrest system for the protected pavement 100 users under situations of risk.
  • a safety life line is advantageous if a section of the protected pavement 100 is installed at a cliff, a bridge, or any other site where a real fall risk exists for people operating outside the same protect pavement 100 for repair or maintenance interventions, or the like.
  • the module 1 comprises one or more eyebolts - items consisting of a suitably sized ring, and a support stem extending therefrom, both made of steel or other material having suitable mechanical features - arranged near the side parapet 4, and preferably outside it.
  • the eyebolts are embedded in the upper side of the box-like pavement element 2, or otherwise secured to the same element 2 by a plate, mounted at the eyebolt support stem end and bolted to the pavement surface.
  • the eyebolts provided with modules 1 are suitably spaced so as to comply, when several modules 1 are installed, the laws and regulations in force, that set a distance lower than 2 meters between two consecutive fall arrest elements.
  • a person who has to word in a situation of risk outside of the side parapet 4 can therefore hook a safety carabiner connected to his harness to the eyebolt, and unfasten it only after being secured to the subsequent eyebolt with a second carabiner.
  • the protected functional pavement 100 can provide for means for mounting a conventional safety life line.
  • the module 1 is provided with anchoring means, fit to fasten a suitable steel cord, that is fixed to the aforesaid anchoring means of every module 1 of the pavement 100 section, subsequently to its installation.
  • a module 1 of the pavement section can be provided with a gate, made in its side parapet 4 according to known techniques.
  • each module is self-supporting, so the preparation of the "bed” is reduced to a simple levelling and, if necessary, to the laying of filler material such as gravel or similar. If the bottom is already levelled and sufficiently resistant, such as asphalt or other structure, the modules can be laid in direct contact.
  • the prefabrication technique reduces the production costs of the modules.
  • the reduced production costs together with the rapidity of installation, makes the modules suitable for pavements for single events such as concerts, trade fairs, sporting events or the like, with the possibility of removing them easily at the end of the event and reuse them, even in another site.
