Definitions

  • the invention relates to a break-through-proof vehicle barrier for preventing the intrusion of vehicles, in particular for use in the defense against terrorist attacks.
  • the construction of the vehicle barrier is intended, among other things, for the use of flat foundation bollards, the color and / or shape of which is adapted to the environment of the place of use.
  • the vehicle barrier has a composite construction that enables it to be adapted to the respective lane width.
  • the bollard arrangement made known according to WO 2018/006125 A1 comprises a bollard and a fixed bollard carrier which are designed so that the bollard can slide relative to the bollard support when a vehicle impacts, the bollard remaining in its original orientation during the sliding movement.
  • the bollard arrangement also includes an energy absorption mechanism for the vehicle to absorb energy, since the bollard slides relative to the bollard support and thus contributes to the deceleration of the vehicle.
  • the invention is based on the applicant's finding that many known bollards tend to non-resiliently change position from an original upright, usually vertical, orientation in response to the impact of the vehicle.
  • vertical alignment and “vertical” are understood to mean an originally upright alignment of a bollard before it is impacted by a vehicle.
  • the disadvantage of this bollard arrangement is the high material expenditure for the impact energy to be absorbed until the impacting vehicle comes to a standstill.
  • a barricade which is designed as a mobile, stationary and / or temporary barrier with mobile obstacles to protect crowds.
  • This temporary barrier includes several mobile barriers.
  • the assemblies serving as mobile obstacles are movably connected to one another by means of composite elements.
  • this temporary barrier vehicles are effectively kept away from crowds and, if the vehicle hits the barrier, the vehicle is brought to a standstill as reliably as possible in a relatively short time and as short a braking distance as possible.
  • this barrier should prevent obstacles from being thrown away and flying as projectiles into the crowd.
  • the mobile structure is intended to enable quick installation and deinstallation.
  • a disadvantage of this solution is the high technical effort required to be able to absorb the direct impact of the vehicle.
  • the bollard device described with US 2014/0017003 A1 is used as a fixed vehicle barrier with a bollard element with a base end and a foundation arrangement adapted for fixed use on the ground.
  • the foundation assembly consists of a housing part which is arranged within the housing part for the storage of the base end of the bollard element together with cementing material for cementing the bollard element for foundation mounting.
  • the inclination of the bollard element relative to the foundation assembly can be freely selected.
  • the base end is fixed on the cementing material and then the cementing material is cured.
  • the bollard element is thus given the desired inclination relative to the foundation assembly.
  • the system and method for supporting bollards according to EP 3 033 454 B1 proposes a solution in which the bollard and the reinforcement mat used are designed in such a way that they can absorb the impact of the vehicle.
  • the previous systems require the bollard to be relatively long and thick and therefore require a large amount of steel.
  • the reinforcement meshes provided above and below the girders only require the amount of steel that is actually required to manufacture the system. The required quantities of steel and the associated manufacturing costs are thereby reduced.
  • the bollard system has several support beams adapted for installation in concrete, several bollards with each bollard attached to a support beam at a point near a beam center, and a reinforcement bar woven between the support beams around the system to reinforce.
  • the disadvantage is that the material expenditure required to absorb the impact energy is still high.
  • the object of the invention is therefore to create a safety barrier which, with reduced material expenditure, reduces the braking time of the impacting vehicle, absorbs greater impact energy and can be adapted to the ambient conditions in a stationary manner.
  • the vehicle barrier according to the invention has means with which the vehicle is braked after it has hit at least one bollard or a group of bollards and, at the same time, the front drive assembly is lifted from the roadway.
  • a A significant part of the impact energy is absorbed and the effect of the front-wheel drive is canceled when the vehicle is subsequently lifted off the road.
  • the bollard assemblies of the assembly are preferably mounted in an axially movable manner with one end in the foundation, preferably to ensure reliable functioning.
  • An optimal use of the bollards intended for different applications is achieved in that the bollards are connected to the bollard assemblies in a height-adjustable manner.
  • the bollard assemblies are designed such that they can be detachably connected to one another.
  • Optimal absorption of the impact energy of the impacting vehicle is effectively achieved in that the mechanical connection of the bollard to the respective bollard assembly is designed as a lever system counteracting the impact.
  • the stationary, interference-free integration of the safety barrier when it is not in use is advantageously achieved in that the bollards are releasably connected to the bollard assemblies in such a way that they can be pushed into the foundation below the bollard assemblies. This avoids a traffic obstruction outside of the operating hours.
  • the composite of bollard assemblies arranged across the width of the lane is formed from bollard assemblies that are firmly connected in groups, of which each group connection has at least two bollard assemblies.
  • the bollard assemblies are effectively installed in the foundation in such a way that they form a level with the road surface.
  • Equally advantageous for ensuring smooth traffic operations when the vehicle barrier is not in use is a design of the bollards and the height adjustment device attached to the bollard assembly in such a way that the upper surface of the bollard after it has been pushed into the ground or into the foundation is level with the road surface Lie level.

  • FIG. 2 shows the composite system with bollard assemblies 5 which can be connected to one another and which extend over the width of the roadway to be protected. Due to the standard designs of the bollard assemblies 5, the vehicle barrier can be used for different lane widths. The number of bollard assemblies 5 to be connected to one another depends on the specific width of the lane. At one end each, the bollard assemblies 5 are movably anchored across the width of the roadway in a flat foundation 1. At the ends of the bollard assemblies 5 axially movable brake flaps 6 are attached, which are introduced in the idle state in the road surface.
  • the movable bearings Bollard assemblies 5 together with the bollards 3 form a lever system which, when the bollard 3 impacts, lifts the vehicle 4 off the road in its front area. By canceling the contact of the vehicle 4 with the roadway, the direction of action of the impact energy is changed. The effect of a front-wheel drive in the vehicle is also canceled.
  • These movably attached brake flaps 6 serve to increase the braking effect on the impacting vehicle 4.

Abstract

L'invention concerne une barrière de sécurité anti-véhicule-bélier pour empêcher l'entrée de véhicules, en particulier pour éviter des attaques terroristes. La construction de la barrière de sécurité est prévue, entre autres, pour utiliser des bornes de protection plates de fondation, dont la conception en termes de couleur et/ou de forme est adaptée à l'environnement du site d'utilisation. De plus, la barrière de sécurité a une construction composite lui permettant d'être adaptée à une largeur de voie particulière. À partir de l'état de la technique, le problème consiste à fournir une barrière de sécurité qui, tout en réduisant les dépenses en matière de matériaux, permet de réduire le temps de freinage du véhicule percutant, absorbe une plus grande quantité d'énergie d'impact et peut être adaptée de manière fixe aux conditions environnementales. Cet objectif est atteint par l'ancrage mobile d'une extrémité d'un ensemble d'unités de borne de protection disposées sur la voie dans une fondation de telle sorte que l'énergie d'impact du véhicule et un mouvement résultant au niveau du point d'ancrage respectif amènent les extrémités opposées des unités de borne de protection à être déplacées vers le haut hors de la fondation et le véhicule percuté est ainsi soulevé de la voie au moyen des unités de borne de protection.
