Definitions

  • the invention relates to a road barrier for vehicles, with a foundation that can be inserted into a recess in the ground, with a recess in the foundation, with a bollard locking part, which is arranged in the recess of the foundation, for vehicles with a preferred direction of travel, which is the direction of impact is directed against the bollard locking part.
  • Road barriers for vehicles are used in particular to cordon off areas that are to be inaccessible to vehicles, especially motor vehicles. These are, for example, pedestrian zones, but also security-relevant areas into which unauthorized vehicles from outside should not enter.
  • Extendable bollards for temporary and reversible blocking of vehicles are known, for example, from DE 199 28 036 A1.
  • a road or road barrier is equipped with a stationary, sleeve-like stand part, the interior of which forms a recess in the floor, and with a locking part that can be extended upwards and lowered downwards relative to it, which in the recessed state is arranged in the recess. This is so arranged vertically extendable in the ground and can block the path or the road if desired.
  • Such movable path or road blocks for vehicles naturally require a drive for the movement, which limits the massiveness and resistance that such path or road blocks can oppose to the impacting vehicles.
  • the task is therefore to propose a road or road block for vehicles that offers more options for a different structure, but is nevertheless economical to manufacture and use.
  • a path or road block for vehicles with a foundation that can be inserted into a recess in the driving surface, with a recess in the foundation with a bollard locking part, which is arranged in the recess of the foundation, for vehicles with a preferred direction of travel, which is directed as the direction of impact against the bollard barrier part, the bollard barrier part being constructed from two or more plates that can be handled separately from one another, the plates being arranged parallel to one another, and the direction of impact being directed against an impact side of the bollard barrier part which is arranged perpendicular to the plates .
  • the task can surprisingly be solved. It must be taken into account that the vehicles that are expected to travel beyond the area to be blocked off always have the same or largely similar direction of travel. If it is a closed off former path or a former road, the course of this road will be followed by the vehicles, namely from the area released for use to the area no longer available for use. If, however, the direction of travel is always the same, the presumed direction of impact of the vehicle on the road block is always the same.
  • the individual plates or layers are significantly lighter, that is to say have less mass, than the complex and large-volume steel structures from the prior art, which have to be installed at an angle. According to the invention, it is sufficient simply to add additional plates by hand. With plates with a mass of less than 55 kg, which can therefore still be manipulated by hand, very many different embodiments can be built.
  • the construction of the bollard locking part from several plates is not accidental or arbitrary, but the individual plates are exactly in the direction of travel or the presumed impact direction of the vehicle. Attempts a crashing vehicle that is, to move a single plate within its plate plane. As a result, each of the plates must be moved parallel to one another in the event of an impact, with even small deviations from the angle, which can usually be regarded as given in the event of an impact, lead to relative movements of the individual plates to one another and thus to corresponding friction and lead to even better energy absorption.
  • the impacting vehicle would almost directly hit a plate surface, namely on the surface of a single plate, with further plates only behind it.
  • the absorption of energy on impact is significantly lower.
  • Each individual plate or layer can have structures with an optimized topology and thus be adapted to different external requirements.
  • These recesses or fastening elements can be provided in a neutral fiber and have bores. It is then possible, for example, to additionally attach fastening elements to block off pedestrian traffic between two bollards, if this is desired. Of course, these fastening elements can also be dismantled again if this is no longer necessary after a concert with restricted access, for example.
  • Completely different elements can also be attached to which, for example, dog leashes, bicycle locks or other elements can be attached.
  • the road or road barriers can also be coupled to one another by means of rigid pipes or rigid solid bars of various cross-sections or by means of flexible connectors such as chains or ropes. If the boundary conditions make this appear sensible, the individual plates or layers can also be arranged laterally at a distance from one another, but of course also without a distance. This means that it is possible to create gaps in the bollards, which was not possible in the prior art.
  • the plates or layers can optionally also be firmly connected to one another, but it is also possible not to firmly connect them to one another in order to achieve certain effects from the relative movement of the layers parallel to one another, for example to influence the preferred directions when braking impacting vehicles through friction effects.
  • the friction between the plates and layers of the plate elements increases the dissipation of the kinetic energy of the impacting vehicle.
  • the plates or layers can also be screwed or glued together to achieve a connection.
  • the functional elements can also be designed in such a way that they also have an attractive design and no additional hoods are required to hide unattractive machine elements from the eyes of the environment. It is also possible to build up the plates or layers from individual elements, which are each monochrome, but have a different combination of different colors. This is not possible with the previous complex road blocks. It is according to the invention For example, it is now conceivable to use a corresponding color mix of the corresponding panels or layers to reproduce country colors or club colors in order to use the barriers of embassy buildings on the one hand, or football stadiums on the other hand, in accordance with the preferred colors of the operators of the areas to be protected.
  • the side surfaces of the outermost plates or layers are also flat and can therefore be used to attach posters, LED screens, coats of arms or laser engravings.
  • the energy absorption occurs specifically when the vehicles collide with the paths or roadblocks through a plastic deformation of the load-bearing structure, i.e. through the squeezing of the layers or plates.
  • laser sheets can be used.
  • Crane construction steel, bainitic steel, steel made of or with martensite phases or other high-strength steels can also be used.
  • fiber composite materials are also suitable for forming panels or layers.
  • Partial areas of the plates or layers in the rear area of the material are generally less relevant to the function. These areas can be used in order to be able to arrange or use plates or layers there that take up a certain three-dimensional design in this layer, for example a palm tree or a star in the side cut.
  • Another advantage is that the use of a large number of plates or layers makes it possible to assign different effects to them, for example to arrange smaller spikes or waves on the impact side of these functional elements for targeted stopping or Damage to the impacting vehicle caused by the road or road block.
  • each individual plate or layer consists of a solid material.
  • the bollard locking part is preferably inserted into a quiver device.
  • This quiver device is housed in the mostly cast foundation or in a recess left free there or formed at the same time. This has the advantage that the quiver device is anchored immovably firmly and particularly stably in the ground.
  • the bollard locking part can now be inserted into this quiver-like device from above.
  • the bollard locking part consists of several panels. The surface normal of each of these plates is horizontal to the ground and perpendicular to the direction of impact. For the viewer, each panel stands like a wall, against the narrow side of which the rolling vehicle collides. All “walls” are parallel to each other and the vehicle drives more or less accordingly less at the same time against all narrow sides of all walls of the bollard barrier part.
  • the bollard barrier made of the different panels gives the impression of being put into the quiver, and the manual handling of the individual panels means that the “quiver” is also filled one after the other.
  • the path or road barrier is preferably characterized in that a quiver device is provided which is arranged in the recess in the foundation and into which the bollard barrier part is inserted with its plates that can be handled separately from one another.
  • the quiver device has at least two recesses which are arranged one behind the other in the direction of impact.
  • This conception has the advantage that the bollard locking part can be inserted into two different recesses and each of these two recesses forms a resistance against the impacting vehicle with the sections of the plates that are inserted into it like a quiver.
  • the impact side of the bollard barrier part is formed by narrow sides of the plates of the bollard barrier part that are arranged next to one another and parallel to one another.
  • the cover of the so-called quiver provided according to the invention can be provided with load-optimized radii.
  • An obstacle in front of or behind the quiver can be used to transfer the load into the foundation over a large area.
  • This obstacle can be, for example, bars, pipes, rectangular cross-sections or a standard rail.
  • Crane construction steel can also be used for the cover of the quiver, furthermore bainitic steel, steel with martensite phases is conceivable and fiber composite materials can also be used for certain applications.
  • the concept according to the invention also allows lighting to be carried out without great effort and in particular without impairing the load-dissipating structures by using a concealed cable feed.
  • the quiver is arranged horizontally.
  • the quiver can be secured with shaped elements to prevent the plate elements from being pulled out, both inside and against the direction of impact and / or orthogonally to it and / or by a combination of these variants.
  • FIG. 1 a perspective schematic representation of an embodiment of the path and road block according to the invention.
  • FIG. 1 shows schematically a very simplified representation of an exemplary embodiment of the present invention with the essential elements.
  • a large number of alternative embodiments are conceivable and can modify various of the elements that are basically also present.
  • a foundation 10 is now embedded in the ground or in the driving surface.
  • a corresponding hole is dug or used in the driving surface and a concrete foundation, which will be explained in more detail below, is poured into it.
  • FIG. 1 it can be seen that the foundation 10 is seated on the upper side 11, which is aligned with the surface of the earth, not shown.
  • the ground adjoins the foundation 10 in the simplified illustration of FIG. 1 on several side surfaces 12.
  • a quiver device 20 is located within the foundation 10 in the central area. This quiver device 20 is preferred by many Embodiments cast in when the foundation 10 is poured, so that it cannot be removed even with considerable forces.
  • the quiver device has two recesses 21 and 22 and a quiver cover 23.
  • the quiver cover 23 is flush with the top side 11 of the foundation 10 and thus also with the surface of the earth and the driving surface.
  • the quiver device 20 is also supported by two reinforcement elements which are cast into the foundation 10.
  • these reinforcement elements 24 and 25 are in the form of rails in order to additionally support the anchoring of the entire quiver device 20 within the foundation 10.
  • rails beams, pipes, plates or rods with rectangular cross-sections can also be used.
  • the two recesses 21 and 22 in the quiver device 20 are not covered by the quiver lid 23. Instead, a bollard locking part 30 is provided here.
  • the bollard barrier part 30 consists of several parallel plates 31, 32, 33, 34. In FIG. 1, four parallel identical plates of one 31, 32, 33, 34 are shown, but a different number of plates is also possible and this does not have to be must all be identical.
  • these plates are each constructed flat, the surface plane being essentially the same plane as the assumed direction of travel of a truck or other vehicle approaching the road block. If such a vehicle were to roll towards the roadblock in the direction of impact 15 and get from the ground to the top 11 of the foundation 10, the vehicle (not shown) would hit the impact side 35 of the bollard blocking part 30 on the left in FIG. As can be seen, this impact side 35 is spanned by the narrow sides of the adjacent plates 31, 32, 33, 34 of the bollard locking part 30.
  • FIG. 1 already shows in the schematic view that the impact side 35 is curved, this curvature being directed upwards towards the approaching vehicle, that is, against the impact direction 15.
  • the advantage of this concept is that the vehicle is pushed down when it hits the impact side 35 of the bollard locking part 30 of the road barrier. This also prevents the vehicle from overcoming the obstacle formed by the road and road block.
  • the plate-shaped construction of the bollard locking part 30 additionally stabilizes this bollard locking part 30.
  • the arrangement of several plates 31, 32, 33, 34 side by side in relation to the direction of the impact leads to the impacting vehicle losing additional kinetic energy if the plates rub against each other when they hit each other or bend against each other and possibly bend in the event of even greater energy input also be destroyed.
  • the plates can also be connected to one another by screwing or gluing. It is also possible to arrange them parallel to one another with a spacing or even at irregular intervals.
  • the construction from several plates also makes it possible to assemble the bollard blocking part 30 by manual manipulation, since it is possible to have each individual plate consist of a mass of less than 55 kilograms. It can therefore be handled by one or a few people in order to successively insert several plates of the bollard locking part 30 into the quiver device 20 or the recesses 21 and 22.
  • a topology-optimized structure can also be provided.
  • the bollard barrier part 30, consisting of the panels 31, 32, 33, 34 arranged next to one another, has a structure similar to an “A”.
  • stiffening struts 38 between the impact side 35 facing the rolling vehicle and the rear side 37 facing away from the rolling vehicle, giving the appearance of an “A”.
  • the result is a total of a plate 31, 32, 33, 34 with an edge facing the vehicle, which is part of the impact side 35 of the entire bollard barrier part 30, and a rear side 37 facing away from the vehicle.
  • the impact side 35 and the rear side 37 are connected to one another by one or more stiffening struts 38.
  • material recesses are formed in the plate 31, 32, 33, 34 between the edges and the stiffening struts 38.
  • the number of plates used in a bollard barrier part 30 also depends on the impact loads that the road barrier is to be able to absorb.
  • the plates must not exceed a certain mass in order to be manually manageable for the personnel involved in creating the roadblock, but this is not a problem, as any impact load can be absorbed by a larger number of plates.
  • the two outer plates 31 and 34 in the embodiment shown have side surfaces 36. These side surfaces can be used to attach posters, advertising screens, company logos, coats of arms or laser engravings or other purposes. If, for example, such a barrier is used next to football stadiums, the club's emblems can be used here.
  • the individual plates 31, 32, 33, 34 of the bollard blocking part 30 can be constructed from crane structural steel, bainitic steel, martensitic phase steel or other high-strength steels, for example. Fiber composite materials can also be considered. In combination with the high-strength steel, plates made of resilient elements can also be used.
  • a height graduation of the plates can also be provided.
  • the modular rigidity of the load-bearing structure in the height direction can be selected and the aim is to destroy or trap various structural components of the impact vehicles. Through this can be taken into account if there are any assumptions about the structure of the impacting vehicles.
  • Crane structural steel, bainitic steel, martensite phase steel, fiber composite materials and other materials can also be used for the elements of the quiver device 20.

  • concealed cable feeds through the foundation 10 into the recesses 21 and 22 of the quiver device 20 and from there into the bollard locking part 30 can be provided, for example, in order to provide lighting. This lighting can be used for design purposes, but also to prevent vehicles from accidentally colliding with the roadblock at night.
  • the design of the structure from several plates can also be used to provide shapes in the non-functionally relevant area of the bollard locking parts 30, for example images of palm trees or stars.
  • the layered construction of several panels has another advantage.
  • areas of a Bollard locking part 30 damage occurs, for example cracks.
  • a crack in one of the plates 31, 32, 33, 34 does not yet result in this crack continuing in adjacent plates. So only one of the plates will be damaged while the others are not affected. This increases the resilience of the entire road and road block, for example, for a mass attack by several vehicles one after the other.
  • the plates 31, 32, 33, 34 of the bollard locking part 30 can also be arranged in accordance with the wedge principle, i.e. at angles of, for example, 15 ° to one another. Self-locking and frictional tensioning against pulling out then arise.
