Definitions
- the present invention relates to a side impact containment system for vehicles, with retention and redirection capacity, composed of metal and wood pieces combined in such a way that the assembly has aesthetic qualities for landscape integration, for use in road safety, such as safety barriers and railings, of application on the lateral and medium roads.
- the safety barriers and pretiles are formed by a series of components that, together and once assembled and inserted into the land or anchored to a slab, have the purpose of resisting vehicle impacts preventing them from passing through them and, thus, guaranteeing protection to third parties and, at the same time, proceeding to their controlled redirection and deceleration, so that the vehicle leaves stable impact and continue running at a reduced speed next to the containment system in the original direction of traffic and, thus, ensure the safety of the occupants of the vehicle and that of other road users.
- metal safety barriers and concrete safety barriers are used within the set of containment systems.
- metal and concrete safety barriers can produce a somewhat "aggressive" unwanted visual environmental impact and, in general, are not easily integrated into a natural environment, so that, in such cases, the so-called “aesthetic” barriers are installed , understanding by them all those that, due to their specific qualities of configuration and composition, are able to visually integrate pleasantly in a natural environment, in a way that is not very attractive and coherent with the environment.
- Stone Walls which may be composed of dry stone or be masonry walls or concrete walls clad externally of stone or, even, concrete walls with printed and colored surface geometries.
- Wooden barriers which can be either (i) solid wood barriers in which both the railings and the insertion or anchor posts are solid pieces of wood or (ii) wooden barriers composed of parts internally or externally armed by metallic elements or metal parts clad externally of wood, the latter being known as mixed metal and wood barriers.
- the mixed wooden metal safety barriers usually correspond to the union by assembly of three basic metal elements:
- the rail (s), longitudinal element (s) arranged horizontally at a certain height and continuously, whose function is to contain and guide the vehicle that impacts it, preventing this one crosses, limiting the transverse deformation and guiding it so that it can be redirected by the system in an appropriate way.
- the rail is always composed of a wooden bar or beam, simple or composite, armed by one or several internal, external or partially inserted metal profiles within the wooden beam.
- the wooden beam or log can have different geometries and configurations: in the form of a complete round log, half round, quadrangular or rectangular or polygonal or other more complex shapes.
- the metal reinforcement profile can be a flat, curved or flat, inner or outer band, or a "U” shaped metal profile with the wings inserted, totally or partially, inside the wooden beam, or a metallic profile in ⁇ C "either occupying a hollow inside the wooden beam or attached externally to it.
- the post formed by a metal profile of section in the form of "U”, “C”, “sigma” or round, square or rectangular tubular section, partially covered in its emerging part of the land by a wooden sheath monopieza, arranged vertically at regular intervals and fixed to the rail (s), whose function is to hold and maintain the rail (s) of the barrier at a certain height during the impact and which, in addition, is the insertion or anchoring element of the barrier in the ground.
- the post When the post is anchored to a concrete slab or to a rock-like ground, the post has in its lower part a base plate with a plurality of holes to be crossed by individual anchor bolts to the ground and is, again, the emerging part on said base plate Ia which is covered with a piece of wood as a cover.
- the separator whose function is, on the one hand, to join the consecutive railings with each other to give them continuity longitudinally and on the other, to join the railings to the fixing posts and to act, eventually, as a deformable element, that is, as an attenuator or absorber of part of the impact energy or simply as a rigid-spacer element to prevent the vehicle wheel from engaging in the post and maintaining the height of the rail during the impact as the post is bending and , with this, the point of union of this one with the stirrup descends, as well as to contribute to the redirection of the vehicle during the impact.
- a deformable element that is, as an attenuator or absorber of part of the impact energy or simply as a rigid-spacer element to prevent the vehicle wheel from engaging in the post and maintaining the height of the rail during the impact as the post is bending and , with this, the point of union of this one with the stirrup descends, as well as to contribute to the redirection of the vehicle during the impact.
- this element consists of metal plates or profiles formed in a more or less complex way, or in tubular profiles of square or rectangular section, open or closed, being able to present assembled wooden elements.
- the side of the vehicle makes contact with the front face of the rail that is the element of the barrier that receives the impact, transmits and propagates it along a stretch of barrier and guides the vehicle towards the exit. If the position of the rail descends in height as a result of the contact with the vehicle, the difference in heights between the center of gravity of the latter and the rail can cause the destabilization of the first, its overturning and even the postage of the barrier.
- the front-side part of the vehicle impacts the barrier, it takes a first contact with the rail and, when this primary contact occurs in front of the center of gravity of the vehicle, the reaction of the barrier prints a rotation movement in the vehicle. direction of redirection.
- the vehicle moves and turns at the same time, maintaining a continuous and stable contact with the rail without impacting the posts, until the rear-side part impacts the rail again.
- This secondary impact occurs behind the center of gravity of the vehicle, it produces a rotation in the opposite direction of the redirective turn, ending the reconduction and giving rise to the exit of the vehicle, once it loses contact with the rail.
- the relationship between the degree of elasticity of the primary and secondary collisions will determine the exit path of the vehicle and define the capacity for reconduction of the barrier, in addition to significantly influencing the maximum transverse deformation thereof.
- the pole responds to the forces transmitted by the rail and caused by the impact of the vehicle, progressively deforming to flexion and torsion, bending around its embedment so that its upper part or head is descending towards the ground.
- the safety barriers formed by railings and posts have a fusibility mechanism in the junction between stirrup and pole, so that, from a certain level of force transmitted to the joint corresponding to a certain degree of deformation of the post, said joint is detached by separating the rail-stirrup assembly from the post.
- the separators both those that act as absorbers and the simple spacers, also function as longitudinal connectors between two consecutive railings, must guarantee the stiffness of the joints between consecutive railings, so that torsions or rotations do not occur relative to each other and the stresses and deformations caused by the impact of a vehicle against the barrier can be transmitted along several consecutive railings without discontinuity, as if the successive rail sections were a single continuous section and were consistently distorted by adopting Plant the shape of a curve.
- the separators currently used provide a type of connection between railings that is insufficient to guarantee the almost complete torsional and rotational "blocking" of the union between two consecutive railings.
- the terminal sections of the sections of mixed safety barriers of wood and metal are executed by folding the railing to the ground level, burying its final end and fixing the section of railing folded by several posts inserted or anchored in the field so that the terminal section acts as an anchor of the barrier section.
- the present invention provides a Side Impact Containment System for vehicles composed of metal and wood parts, with aesthetic qualities and with high containment and redirection capabilities that, simultaneously, have the following advantageous technical characteristics with respect to the State of the Art , where the problems that they present are overcome:
- the railings of the mixed metal and wood barrier are constituted by two or more logs of wood, giving the rail a certain deformability, reducing the manufacturing cost and reducing the risk of warping.
- the railings of the mixed metal and wood barrier are constituted by two or more logs of wood, of identical section, preferably rectangular with their larger sides arranged vertically, square, polygonal, circular or semi-circular, assembled on the same metal profile that internally reinforces the rail, the wooden logs attached to it by means of suitable fixing means and connected in longitudinal direction the adjacent logs that form the same rail, with each other, by means of connecting metal plates arranged vertically and inserted in vertical grooves to the effect, practiced at the ends of the wood logs, by means of adequate fixing means.
- This new rail configuration with several logs connected by metal plates and a single reinforcement metal profile has three advantages: a) .- It gives the rail a certain capacity to deform to bending, taking advantage of the straight sections between each two adjacent logs of the same railing (railing sections that lack wood) as "false joints". This small flexibility of the rail, which would otherwise behave as a totally rigid beam, results in an improvement of the deformed line of the rail during contact with the vehicle because one is achieved. warped more curve and less
- the section of the metal profile in the form of "sigma”, with a thin wall, with a soul or loin significantly larger than the wings, allows the "notch" to be the one that provides sufficient rigidity for the desired behavior, without the need to achieve it by increasing the thickness of the wall as would happen in the case of a metal profile with a section in the form of ⁇ U ", which would increase the costs of said profile and unnecessarily increase the stiffness of the wings.
- the fragmentation of the piece of wood or logs of the rail in two or more sections means a significant reduction in production costs c) .
- the warping or "turning" effect of the mixed metal and wood barrier railings caused by the dried, natural or artificial, in warehouse or the weather, of the wood that constitutes it is noticeably inferior the shorter the wood logs.
- the fragmentation of the log of wood broken down longitudinally into two or more pieces results in a railing without risk of warping caused by the drying of the wood.
- (II) .- a new type of spacer separator that, in addition to fulfilling all the functions of this component in this type of mixed barriers (distance the base of the pole from the wheels of the vehicle during the impact, maintain the height of the rail during the deformation of the post, incorporating all or part of the device for the fusible joint mechanism between railings and posts, joining the railings to the post so that it is holding them and joining the consecutive railings together to give longitudinal continuity to the barrier) offers , due to its configuration, composition and connections with other components, guarantees that the successive consecutive rail sections behave as a single continuous section without the appearance of relative torsions and rotations between two consecutive or adjacent railings.
- the metal support is preferably configured as a section bar “omega” lying laterally, with the two flanges or feet and the central spine of Ia or omega “arranged vertically and wings Ia” omega “horizontal or slightly inclined.
- the stirrup is placed in the barrier, longitudinally between two consecutive or adjacent railings and transversely between them and the post, so that both tabs of the stirrup rest on the rear face of the rail and the soul or spine It is central to the post, either directly or by means of a support plate.
- the flanges have a plurality of holes, preferably aligned, to be traversed by the joining elements, preferably bolted, between the railings and the stirrup.
- each of the bolted joint alignments It includes unions located in both consecutive railings.
- the connecting elements between the consecutive railings and the stirrup successively pass through holes or holes arranged in the soul of the steel profile of the rail and the corresponding holes or holes of the stirrup flanges.
- These connecting screws between the rail and the stirrup are preferably placed horizontally, so that the head of the screw or bolt is imprisoned between the inner wall of the core or spine of the metal profile of the rail and the wooden log of the rail, the rod leaving horizontally through the holes of the metal profile of the rail towards the rear or opposite to the traffic. In this way the screws are imprisoned in the rail.
- the corresponding hole in the core or spine of the metal profile of the rail is preferably square as well as the neck of the screw so that, by fitting the neck of the thyme into the hole of the profile the screw is not only a prisoner but its rotation is also blocked, allowing tightening.
- a metal washer preferably square, rectangular or circular, is placed between the head of the screw and the inner wall of the metal profile of the rail, with which the environment of the hole is reinforced.
- the metal profile preferably used to reinforce the rail is "sigma" shaped, that is, in the way that results from making a partial notch centered on the spine or soul of a
- the rear face of the log can have a recess or recess, approximately rectangular in shape, of length slightly greater than the height. of the soul or spine of the metal profile "sigma" and of depth slightly greater than the height of the central notch of the metal profile in the form of "sigma".
- the stirrup has on its back or core, arranged vertically and located on the opposite side of the tabs in contact with the rear face of the rail, means for joining the metal post, preferably screwed and formed by a single screw, successively crossing the stirrup spine, a support plate, the front part of the wooden sheath and a hole in the metal post.
- the breakaway attachment between the support and post is achieved by means of a metal section piece preferably as n U "assembled in the interior of the support and fixed thereto, preferably by screw connections, arranged so that the soul or loin The inner piece rests against the inner wall of the soul or spine of the stirrup section in the form of ⁇ omega "lying down.
- This inner part has a star-shaped hole or hole intended to be crossed by the head of the screw or bolt connecting between stirrup and pole, with the head of the screw or bolt, preferably hexagonal, preferably placed inside the stirrup so that the rod of the screw or bolt, arranged horizontally or with little inclination and perpendicularly to the barrier, successively crosses the "star" shaped hole of the piece in W U "inside the stirrup, the wall of the soul or spine from the stirrup, the front part of the wooden pole sheath and the metal pole wall.
- stirrup is composed of two metal parts: a main piece of section in the form of
- Both the "U" inner part and the main stirrup piece have in their soul or spine holes to allow the union between the two, preferably screwed.
- the holes in the spines of both must correspond so that the joining means, preferably screwed, can pass successively through both parts.
- the combination of homologous holes in both pieces so that a round shaped hole of one piece corresponds to one elongated in the longitudinal direction of the barrier in the other piece, allows a certain longitudinal displacement of the piece in "U" inside the stirrup with respect to the main stirrup piece, which makes it possible to adjust the longitudinal position of the railings with respect to the pole.
- the hole or hole in the core or spine of the inner part of the stirrup intended to be crossed by the means of connection, preferably screw or bolt, between stirrup and post to constitute the fusible joint has a special star-shaped contour formed by a central hole preferably circular, oval, quadrangular or substantially rounded, from which a plurality of elongated holes of small width (that is, much longer than the width) and arranged in radial configuration around the central hole.
- the diameter or size of the central hole of the star-shaped hole is larger than the diameter of the screw or bolt rod and smaller than the diameter or size of the screw or bolt head.
- the joining means between the different slats that make up the metal post sheath are preferably screws, bolts, screws, nails, staples or glued surfaces and the resistance of the resulting joints is sufficient to guarantee the integrity and stability of the sheath assembly until its definitive assembly in the barrier but not enough to prevent an easy breakage of the sheath assembly, disassembling in its component slats, which come off, when the post bends as a result of the forces transmitted from the rail caused by the impact of a vehicle against the safety barrier.
- the production cost of the sheath is lower, as it does not have to carry out the mechanization work and avoid the waste produced as a decrease when making the hollow of the cover that houses the metal post in case of obtaining it in one piece. It is avoided that during the drying of the wood the lateral wings of the cover of a single piece of wood "open” outwards, deforming and damaging Ia. aesthetic quality of the barrier.
- the metal plate works not only as a protective shield but also as a distributor of the efforts that, if not present, would be concentrated in the contact edge of the stirrup with the wooden sheath. Said efforts, on the other hand, are not sufficient to deform the metal plate, provided that the thickness thereof is adequate.
- the metal support plate between stirrup and sheath can be extended towards the ground, as an arm, to support a metal or plastic screen, designed to protect motorcyclists and cyclists against a direct impact against the posts of the barrier or against atravesa ment of the barrier, which could leave your body exposed to risks (obstacles, slopes, "(7) to justify the implantation of the same.
- the terminal sections are usually constructed by folding the handrail to ground level and burying its end attached to a terminal metal piece generally in the form of a "hook” and fixing said folded handrail in one or more metal posts inserted or interlocked in the ground. , joined to the railing folded through metal parts.
- the joints between the posts fixed to the folded rail should to withstand all the tension not being probably able to do so, breaking and releasing the rail section, which would be released without tension, thus losing the barrier all its containment capacity.
