Description

[0001] MODULE FOR A ROAD BARRIER.

[0002] TECHNICAL FIELD

[0003] The present invention relates to a module for a road barrier, in particular for defining a safety road barrier.

[0004] The present invention also relates to a road barrier, in particular a safety road barrier.

[0005] STATE OF THE ART

[0006] In the field of safety road barriers, a first type of road barrier is known, also called “guard-rail” and usually made of metal, which comprises a plurality of uprights, normally arranged at a constant distance from each other and planted in the ground, on which a shaped metal sheet is fixed, with an open section, which extends longitudinally with respect to the road surface.

[0007] Another type of road barrier is also known, called “Jersey” in reference to the first US state to have used it, which is instead made up of a plurality of modular shaped elements arranged in series. These modular elements are usually made of concrete or plastic, to be easily moved individually even within temporary road construction sites, but versions with uprights fixed to the ground and a shaped metal sheet casing of the box type have also been proposed. The “Jersey” type barrier has a profile that has, in cross-section, a sloped surface near the base. Thanks to its construction, if the tires of a vehicle, in the event of a skid, end up surmounting said sloped surface, this favors the return of the vehicle towards the inside of the carriageway, avoiding both the impact against the upper part of the barrier and the climbing towards the other carriageway.

[0008] The Jersey barriers available today, both with and without a constraint for fixing to the ground, are not easily movable and adaptable to any planimetric reconfigurations of the road platform.

[0009] A known solution for connecting two adjacent barrier sections is described in US9127424.

[0176] Conveniently, each barrier module comprises a profile which has, in crosssection, a base which comprises a sloped surface 13 and which is wider than the upper part.

[0177] The present invention relates to a module 1 for a “jersey” type road barrier comprising a device 2 for joining the module 1 with a contiguous module T

[0178] Preferably, the device 2 joining the modules 1 , T can comprise a vertical pin 25' and a sliding system 22 operated by a lever 50' and which is configured to cause the coupling / engagement of a vertical pin 25' in a fixing seat 26 provided on the contiguous module T.

More preferably, the fixing system 3 to the ground may comprise a first transverse support plate 31 , which is equipped with nails 33 for fixing to the ground, and a sliding vertical stop rod 32.

[0180] Preferably, the module 1 is configured for, and is intended to be used in a “jersey” type road barrier, i.e. a barrier that is made up of a plurality of shaped modular elements (modules), arranged in series, and with a profile that has, in cross-section, a base with a sloped surface 13 and that is wider than its upper part.

[0181] Preferably, module 1 may comprise a shaped external box-like body 10 made of rigid material, for example steel, such as galvanized steel or corten steel.

[0182] Preferably, module 1 comprises beams 11 (or other elongated, horizontally extending rigid components) inside the shaped external box-like body 10.

[0183] Preferably, the joint device 2 comprises a sliding system 22 provided with and operable by an articulation lever 50'.

[0184] Preferably, the module 1 may comprise a fixing system 3 to the ground (or to the flooring).

[0186] Preferably, the sliding system 22 comprises a box-like body 22' resting on elements 23 made of rigid material, for example polyzene, which slides on nylon wheels.

[0187] In a possible and preferred embodiment, the device 2 may comprise a sliding box-like body 22' that actuates a vertical pin 25' made of rigid material, for example steel, which fits into a seat 26 of the contiguous module T, effectively constituting a block of the hinge system 40 for connection and articulation between two contiguous barrier modules 1 and 1'.

[0188] To allow the correct movement of the lever 50' and the maintenance of the selected position of the lever itself, two counter-acting springs 52 act on the sliding box-like body 22'. The articulation portions of the hinge system 40 therefore allow - when the system 3 for fixing to the ground is unlocked (i.e. is in the deactivated condition) - to orient the "jersey" type barrier module 1 with respect to the contiguous jersey module T according to an angle that is not predefined but chosen by the manoeuvring operator.

[0189] Therefore, unlike the Jersey type barriers currently available on the market, the solution according to the invention allows to accommodate road surface movements due to the need to reconfigure the planimetric layout of the safety device, maintaining the continuity and structural integrity of the barrier.

[0190] During a possible impact of a vehicle, the barrier module 1 of the present invention, in addition to providing the traditional straightening effect of the “Jersey” profile, ensures sufficient lateral stiffness even along curved trajectories, both in static and dynamic configuration, i.e. while it is being moved to be retraced along the road axis.

[0191] The solution according to the invention is particularly effective and, compared to the previous technique, proposes a module for a road barrier with the typical safety characteristics of “Jersey” type barriers, but with particularly excellent structural elasticity, torsion-flexural resistance and load resistance.

[0192] These Jersey-type barriers are made entirely of rigid material, for example galvanized steel or corten steel, and assembled by joining a plurality of identical modules or components in series, using appropriate joining elements.

[0193] It is understood, however, that the invention is not to be considered limited to a particular rectilinear arrangement, which constitutes only an exemplary embodiment thereof, but that various variants are possible, all within the reach of a technician of the technical field, without thereby departing from the scope of protection of the invention itself as defined by the attached claims.

[0194] Furthermore, the length of the installation, i.e. the number of “jersey” barrier modules connected to each other, can also be very different from that described and illustrated.

[0195] In a possible embodiment not illustrated in the figures and to be considered equivalent to that illustrated in the figures, the module 1 comprises a coupling member 25 at said second longitudinal end of said at least one beam 11 of said module 1 , while the device 2 of the same module comprises a corresponding seat 26 which:

[0196] - is moved by the movable element 22 of the device itself,

[0197] - is provided at said first longitudinal end of said at least one beam 11 of said module 1 ,

[0198] - is configured to receive the coupling member 25, or vice versa (in the sense that the device 2 of the module can comprise a seat 26 while a coupling member 25 is provided at said second longitudinal end), of a downstream, or upstream, contiguous module 1' to thus prevent rotation around said first axis X1 between said module and the contiguous module 1'.

[0199] In one possible embodiment, module 1 may have:

[0200] - a longitudinal extension (i.e. along a direction parallel to Y) greater than 1 metre, for example approximately 2 - 2.1 metres,

[0201] - a width (corresponding to the extension along a direction parallel to Z) lower than 1 metre, for example approximately 0.85 - 0.87 metres,

[0202] - a height (corresponding to the extension along a direction parallel to the X1 axis) lower than 1 metre, for example approximately 0.82 metres.

[0203] In a possible embodiment, the module 1 can have a weight of approximately 200 kg.

[0204] In a possible embodiment, the ground anchoring members 33 have a length equal to or greater than 0.1 metres, so as to penetrate into the ground or pavement for a distance greater than 0.05 metres, for example approximately 0.08 metres.

[0205] In a possible embodiment, the road barrier has a length greater than approximately 80 meters and can comprise a sequence of at least forty modules 1 , T.

[0206] Installation method

[0207] The present invention also relates to a method of installation of a road barrier comprising a sequence of at least two modules, as described above, wherein:

[0208] - a module 1 is hinged with an upstream or downstream contiguous module T around a first substantially vertical axis X1 ; in particular, to this end, the first hinging means 42 of the module 1 are made to cooperate with the second hinging means 43 of the contiguous module T to thus define a hinge system 40, which rotates around the first substantially vertical axis X1 , between module 1 and the contiguous module T;

[0209] - the actuation member 50 of the device 2 of the module 1 is acted upon to bring said device into the second condition wherein the device itself prevents rotation around said first axis X1 between said module and the contiguous module T,

[0210] - preferably, if ground fixing is foreseen or required, the system 3 for fixing to the ground of the module 1 is then brought to the activation condition wherein the ground fixing means 30 are anchored / fixed to the ground.

[0211] The present invention also relates to a method for varying the arrangement of an already installed road barrier, maintaining the longitudinal continuity of the barrier itself, and wherein said road barrier comprises a sequence of at least two modules, as described above. In particular, said method provides for moving each module 1 of the road barrier in a longitudinal and / or transverse direction by carrying out the following operations:

[0212] - firstly - if ground fixing is foreseen or required - the control member 32 is used to bring the system 3 for fixing to the ground into the deactivation condition,

[0213] - the actuation member 50 of the device 2 of the module 1 is acted upon to bring said device into the first condition wherein the device itself allows rotation around said first axis X1 between said module 1 and the contiguous module 1 ',

[0214] - the module 1 is translated (preferably with the support of a mechanical arm or other machinery) in a transverse and / or longitudinal direction with respect to the direction of traffic (i.e. the module is translated substantially in one or both of the two directions perpendicular to a direction parallel to the first axis X1 ) until it is thereby brought into the new / different desired arrangement,

[0215] - once the new / different desired arrangement has been reached, the actuation member 50 of the device 2 of the module 1 is acted upon to bring said device into the second condition wherein the device itself prevents rotation around said first axis X1 between said module 1 and the contiguous module 1 ',

[0216] - preferably, if ground fixing is foreseen or required, the system 3 for fixing to the ground of the module 1 is then brought to the activation condition wherein the ground fixing means 30 are anchored / fixed to the ground.

[0217] Advantages

[0218] From what has been said it is clear that the solution according to the invention achieves the intended purposes.

[0219] In particular, the safety road barrier, which is defined and obtained with the modules according to the invention, has excellent values in terms of structural elasticity, torsion-flexural resistance and load resistance, and at the same time it is also removable (i.e. it is easily movable, translatable and removable from one place to another as needed). In particular, the presence of an element - which can be locked / unlocked when necessary - for a joint / hinge between the modules of the safety road barrier guarantees the removability of the barrier system, which can be used both as lateral protection and as a traffic divider. Advantageously, the solution according to the invention allows the rapid locking / unlocking of the connecting hinge of two contiguous barrier modules, preferably each provided with a plate or bracket for connection to the underlying pavement.

[0220] More specifically, the module according to the present invention is advantageous in that it allows to define a physical barrier - to protect people and objects from dangers such as moving and derailed vehicles - that is robust and, at the same time, flexible, easily installable and removable. This improves safety for road construction site operators and also improves the overall efficiency and productivity of the construction site itself.

[0221] Advantageously, the module according to the present invention can be used to define a temporary safety road barrier in road construction sites or in emergency situations. In particular, the road barrier thus obtained defines a physical barrier to prevent the intrusion of derailed vehicles, thus protecting the construction site operators and reducing the risk of serious accidents for road users.

[0222] The module according to the present invention can be advantageously used in short and medium-term construction sites, creating a more protected and safe working environment, and can also be used in long-term construction sites, offering a robust and long-lasting solution.

[0223] Advantageously, the module according to the present invention has been tested and certified in class H2 according to EN1317-2.

[0224] In particular, the module according to the present invention is able to absorb the kinetic energy of a colliding vehicle (class H2 - 287 kJ) to minimize damage to the vehicle and reduce the risk of injury to the occupants and redirect the vehicle in the direction of traffic.

[0225] Advantageously, the module according to the present invention - being made entirely or mostly of durable materials such as Corten steel or hot-dip galvanized steel (e.g. S355JR steel) - has a particularly long service life and allows for reduced maintenance costs.

[0226] Advantageously, in the construction of dynamic construction sites, which differ from traditional ones, the solution allows the installation of modules for a safety road barrier with extreme speed of movement, thus making it possible to reconfigure the construction site in a parallel and / or perpendicular way to the direction of traffic in a short time.

[0227] The present invention has been illustrated in some of its preferred embodiments, but it is understood that executive variations may be made in practice, without however departing from the scope of protection of the present patent for industrial invention.
