Definitions
- Deformable separator device for road safety barrier for impact of vehicles used between a vertical support-support element or pole and a horizontal impact element or rail
- the present invention relates to a deformable separating device, which functions interposed between the horizontal fences or railings and the vertical support post of a side impact containment system of vehicles with high containment, redirection and energy absorption capacity, of use in road equipment for road safety, such as safety barriers, for widespread use on side embankments and on medium-sized roads and, sporadically, on road bridge board edges.
- vehicle restraint systems meaning any device installed on a road whose purpose is to provide retention and redirection to a vehicle that, out of control, leaves the roadway, reducing the severity of accidents caused , in such a way that the damages and injuries are limited both for its occupants and for the rest of the road users and other persons or objects located in the vicinity.
- metal safety barriers used in medium and medium margins of roads, and metal parapets, analogous to safety barriers, but specifically designed for edges of boards of passage works (bridges, viaducts, etc.), coronations of supporting walls, and similar works.
- These elements have the purpose of resisting vehicle impacts, preventing them from passing through them and, thus, guaranteeing protection to third parties and proceeding to their controlled redirection and deceleration, so that the vehicle leaves the impact stable and continues at a speed reduced along with the containment system in the original direction of traffic and, thus, guarantee the safety of the occupants of the vehicle and that of other road users.
- a containment system successfully fulfills a crash test on a real scale when the requirements and acceptance criteria defined in the regulations are met in terms of level of containment, severity of impact, deformation and exit angle, and therefore guarantees adequate conditions of security, mainly, for the occupants of the impacted vehicle and third parties. It is then claimed that a containment system has the capacity to contain a certain type vehicle.
- a high containment system (specifically designed to receive the crash of heavy vehicles such as trucks and coaches) must pass the full-scale crash tests of both heavy vehicles
- trucks and coaches such as light vehicles (cars).
- the level of high containment H2 requires the passing of the TB51 test (impact of a 13,000 kg coach, at 70Km / h speed, and with an angle of collision against the containment system of 20 °) plus the TBIl test (impact of a tourism of 900 Kg. weight, at lOOKm / h speed, and with an angle of shock against the 20 ° containment system).
- Safety barriers designed to withstand heavy vehicle impacts generally have operating mechanisms capable of responding with a different behavior to the impact of a light vehicle and a heavy one.
- the success in the design of such barriers consists precisely in the commitment to achieve good behavior in the face of two different types of impact, with the same barrier.
- the metal safety barriers correspond to the union of three basic metal elements and an optional room:
- the fence (s) or rail (s), longitudinal elements arranged (s) horisontally on one or several levels at a certain height and continuously, whose function is to contain and guide the vehicle that the impacts, preventing it from passing through it, limiting transverse deformation and guiding it so that it can be redirected by the system adequate.
- the fence can have different configurations: one or several longitudinal profiles of open or cased section, in the form of double or triple wave or in the form of "C" or "sigma", connected to the post by means of a separating element; cables or tensioned metal rods attached directly to the post; longitudinal profiles in the form of double or triple wave joined in its lower part to metal sheets with free movement capacity and calibrated to oppose a certain resistance to an impact.
- the post placed vertically at regular intervals and fixed to the (s) fence (s) or railing (s), whose function is to hold and maintain (s) fence (s) or railing (s) of barrier at a certain height during impact.
- the posts are generally metal profiles of section in "C”, in “U”, in “I”, in “Sigma”, in “Z”, round or rectangular closed tubular sections or other type of section, which are inserted in a embankment or medium of a road so that a part of its length is embedded in the ground or through a plate with anchor bolts inserted in the ground.
- the post deforms to a greater or lesser extent by bending and / or twisting with respect to the recess or anchor section.
- the separating element is the intermediate connecting piece between a fence or rail and the post, whose function is to:
- the separator is called an energy absorber.
- the absorber function of the separator is characteristic of high containment barriers since these barriers have a very robust or rigid basic structure, composed of the fence (s) and robust posts arranged at a short distance capable of containing heavy vehicles and, therefore, This structure is too rigid for the impact of light vehicles.
- the separator-absorber is specifically designed to reduce the severity of the impact of light vehicles against these rigid basic structures, softening in contact with the pole and favoring the redirection of the vehicle.
- this element consists of a single component or a set assembled from metal plates and / or profiles formed in a more or less complex way, or in tubular profiles of square or rectangular section, open or closed.
- the absorber or separator element consists of cylinders of resistant elastic material filled with foam or similar material placed between the fences and the post or outer wall; or even by a triangular semi-truss metal structure that acts at the same time as absorber and pole, allowing the barrier to move in case of impact.
- the ability to Energy absorption of a safety barrier is achieved by means of elastic adapters as a cover located on the fences or railings.
- a horizontal continuous back brace that longitudinally connects the barrier posts at the back of the barrier, joining the consecutive posts by their upper head or the consecutive separators by their rear.
- the brace has the function of:
- the present invention provides a high-performance separator-absorber device that is integrated into a side-impact containment system of high-capacity containment and energy-absorbing vehicles, as well as certain innovative and specific features of the post and rear brace that are necessary and concurring to achieve the technical advantages that the separator-absorber device brings to the operation of the safety barrier with respect to the
- the deformable separator (3) of the invention described below is integrated into a safety barrier composed of one or several horizontal continuous fences or railings (1) and (1 ') or any other horizontal impact element, supported through the separator (3) by vertical fasteners or vertical posts (2) inserted in the ground (7) at regular intervals and a continuous horizontal back brace (4) that connects to the post (2) at its back.
- the deformable separator (3) is basically composed of two metal parts (5) and (6), both of U-shaped section, each with a central face or spine and two lateral faces or parallel wings perpendicular to each other. the central face and with two straight, sharp or rounded edges, between the central face and each of the lateral faces, the relative position of the two pieces being "U" (5) and (6) such that the axes Longitudinal of both are parallel or substantially parallel to each other and are arranged vertically or with little inclination.
- the two pieces in “U” are assembled forming a single body in such a way that the open or “throats” of each piece in “U” are of different width and are facing each other leaving a piece in "U” partially contained within of the "throat” of the other piece in "U”, with the lateral faces of both pieces very close or in direct contact butt two to two and joined the pieces to each other by means of bolts (8) that successively cross their lateral faces perpendicularly to its longitudinal axis.
- One of the "U” pieces (5) is fixed, preferably by means of several bolts that pass through one or more holes.
- the other "U” piece (6) is fixed, preferably by means of several bolts that pass through holes (10) in its central face, which forms the soul or “spine” of the "U” piece, to the post (2) of the safety barrier and, therefore, occupies a posterior position in the separator (3).
- it is the "throat” of the previous "U” piece (5) that externally embraces the "throat” of the subsequent "U” piece (6).
- the holes (11) and (H ') which, for this purpose, have been made on both side faces of one of the "U" pieces, preferably the one that occupies the previous position (5), have their contour in the form of eyelet or keyhole (11) and (H ') with a round or similar hole (13) and (13') posterior in diameter or larger than the diameter of the pin rod (8) and an elongated anterior hole (14 ) and (14 ') connected to the rear (13) and (13') and of a width smaller than the diameter of the pin rod (8), said elongated hole being able to be straight or curved and, preferably, with a straight section communicated in the round hole and a curved section before the straight section.
- Each side face of this previous "U” piece (5) can have two or more holes in the shape of a buttonhole or keyhole (11) and (H ') located at different heights.
- the length of the elongated hollow section is preferably greater as the hole corresponds to a lower position along the vertical or slightly inclined longitudinal axis of the "U" piece.
- the holes made (12) and (12 ') on the side faces of the other "U" piece, preferably the rear (6), are circular or round in diameter with a diameter greater than the diameter of the rod of the connecting bolt.
- each hole on one side face another symmetrical one corresponds to the plane parallel to the lateral faces containing the longitudinal axis of the "U" piece located on the other side side of it.
- the union between the two pieces in "U” made in this way allows them to be able to partially move from one to the other by translation in a vertical plane staying one inside the other over a certain distance and, thanks to the section curved of the previous section of the holes in the form of eyelets or keyhole of the lateral faces of one of them, of rotating with respect to each other around the axis determined by the connecting bolts.
- a constructive alternative of the separator consists in replacing the rear "U" part (6) with a square or rectangular section tube (6 ') whose axis is vertical or slightly inclined, everything described above regarding the holes for the side faces of the tube that would correspond to the side faces of the rear "U” piece (6) and for the back side of the tube that would correspond to the center face of the rear "U” piece
- the rear "U” part (6) of the separator has on its central face or core one or more holes (10) to allow its connection with the post (2) of the barrier.
- Said unions are preferably of the screwed type, with bolts (20) of preferably hexagonal head (21), although it can also be quadrangular or round, whose rod passes successively through the corresponding hole (10) in the subsequent "U” piece. (6) and the post hole (22), such that the hexagonal head (21) of the screw is inside the spacer (3) and the corresponding nut (23) and washer (24) inside the post (2) .
- the holes (10) in the central face O "spine" of the rear "U” piece (6) have a special star-shaped contour formed by a central hole (25) preferably circular or substantially rounded from which a plurality comes out of elongated holes (26) of small width
- the diameter or size of the central hole (25) of the star-shaped hole (10) is larger than the diameter of the bolt rod (20) but smaller than the diameter or size of the head (21) of the bolt.
- an innovative deformable separator is constructed that provides the barrier with excellent performance when faced with the impact of vehicles.
- Rear "U” that is fixed on the post.
- the relative movement between the parts of the separator is of displacement by translation first and then rotation when moving the previous piece in relation to the subsequent one, preferably hugging it on the outside, holding the connecting bolts that join both pieces in "U” and tearing. the elongated hollow of the lateral holes of the previous piece. in "U”.
- the different phases of this relative movement between the "U” pieces of the separator before an action transmitted from the fence are shown in FIG. 5. With this movement it is possible to produce a lateral deformation of the barrier of sufficient magnitude for the adequate reconduction of the vehicle during and after the impact and with sufficient energy absorption to produce a reduced deceleration to decrease the severity of the impact.
- the energy absorption is controlled by tearing the elongated holes in the eyelet-shaped holes of the side faces of one of the "U" metal parts, caused by the pin rod thanks to the difference between the diameter of the pin rod (larger) and elongated hole width (smaller).
- the separator Faced with the impact of a heavy vehicle, the separator, which receives the impact forces from the fence (s) or rail (s), deforms in the same way as described above but now the impact energy it is enough to make the pole rotate a certain angle in the ground around the embedment in the ground and bend slightly, thus creating a transverse deformation space that allows adequate containment and redirection of the heavy vehicle.
- FIG. 6 shows the different stages of
- the release of the fusible joint from a certain level of effort not only prevents the reduction of the height of the fence (s) or rail (s) but also, when decoupling the fence (s) -separator assembly of the post transmits the efforts derived from the impact to the adjacent posts, thus distributing and propagating the deformation along the barrier, which allows it to reach the high containment and redirection capacity with which it has been conceived.
- tie rod The arrangement of a tie with a certain degree of stiffness also helps to distribute the forces between posts before the release of the fusible joint occurs.
- the primary function of the tie rod is to compensate the torsional stresses in the post head generated by the torque produced by the longitudinal component (in the same direction as the barrier) of the vehicle's impact force on the fence ( s) or rail (s) or the horizontal impact element whose arm is precisely the distance between them and the pole, that is, the transverse width of the separator.
- the post would twist instead of bending and, with such torsion, the separator would also twist in equal or greater extent with which barrier would lose the ability to function as described above.
- the characteristics of the deformable separator element (3) that have been described above and that constitute an innovation on the state of the art are not, by themselves, sufficient to completely guarantee the high containment and redirection behavior with which it has been Designed this type of barriers.
- the barrier in which the separator (3) is integrated has two specific characteristics that are also innovative:
- the post (2) of the barrier which can be of section in "C”, in “U”, in “Sigma” or similar, has two steel plates
- each plate contained in a plane parallel to the soul of the post (2), connects the side faces of the profile "C", "U”, “Sigma” or similar of the post (2) .
- the upper steel plate (27) is intended to prevent excessive deformation of the post head (2).
- the lower plate (28) is intended to resist the tendency to twist at the base of the post and force it to rotate and bend transversely while staying in the same vertical plane.
- the rear brace (4) of the barrier which is fixed to the posts (2) by the rear face of the head of the same and that successively connects the consecutive posts to each other, has a trapezoidal type profile.
- This trapezoidal profile gives it some resistance to both bending and torsion, which allows the tie rod (4) to act as a compensator for the large torsional stresses that the post (2) is subjected to on its head during the impact of a heavy vehicle and, in turn, limits the transverse deformation of the barrier by distributing forces between consecutive posts until the release of the fuse link between separator (3) and post (2) occurs.
- Consecutive straps (4) ⁇ are joined together by partial overlap with preferably bolted joint.
- the overlapping screws (29) and (30) of the tie rod can also be both the connecting screws (30) between the tie rod (4) and the rear face of the post (2) through the holes ( 20) of the post head (2).
