    Vehicle barrier, obstacle protector and method for turning a vehicle and / or protecting an obstacle
    The present invention relates to a vehicle barrier. Such a vehicle barrier or guardrail is, for example, placed along a motorway for catching a vehicle that is in danger of getting off the road.
    Vehicle barriers known from practice comprise a post to which a board or profile is attached which extends in the longitudinal direction of the motorway along which the vehicle barrier is placed.
    A problem with known vehicle barriers is that they cannot absorb the full impact of a collision, or that a very heavy version of the vehicle barrier is required for this.
    The object of the present invention is to provide a vehicle barrier that can absorb a sufficiently large impact in an efficient and effective manner.
    This object is achieved with the vehicle barrier according to the present invention, the vehicle barrier comprising: - a number of posts; - a profile extending at a distance along the uprights; and - a number of spacers for keeping the profile of the posts at a distance, the spacers comprising a kink element.
    By providing buckling elements comprising spacers, it is achieved that the profile or the board is at a distance from the upright. The impact of, for example, a collision vehicle can be absorbed by the use of a buckling element. In particular, the buckling element ensures an optimum and controllable peak delay.
    An additional advantage of the vehicle retainer according to the present invention is that it achieves a further reduced safety risk in that the spacers bend along, and thereby absorb a part of the occurring forces, without there being any protruding parts or pins that can lead to injuries or further damage to the vehicle.
    Another additional advantage of the vehicle barrier according to the present invention is that the uprights are damaged less quickly in the event of a collision due to the improved absorption of the occurring forces by the buckling elements. This ensures that, for example, the repair times are reduced. As a result, there will be less traffic delays due to such repair work.
    A further additional advantage is that the vehicle barrier according to the invention has a limited number of different parts. These parts can furthermore be produced in a relatively simple manner. In addition, due to the improved peak deceleration, no heavy version of the vehicle barrier is required. This makes production easier and the costs are relatively lower. This has, for example, the possible consequence that, due to the lower costs, a larger part of a road can be provided with vehicle barriers.
    The kink element preferably comprises a kink plate. Such a bending plate or bending plate is capable of absorbing a relatively large force. A kind of crumple zone is hereby introduced in the vehicle barrier. The buckle plates have hereby shown to accomplish this in an effective and efficient manner.
    In an advantageous preferred embodiment according to the present invention, the buckling element is provided with a thickness of at least 3 mm, and the thickness is preferably in the range of 3.5 to 5.0 mm.
    By providing a thickness for the buckling element, preferably a buckle plate, of at least 3 mm, a sufficient resistance is achieved with which the impact of a collision can be effectively absorbed. Tests have shown that in particular a thickness in the range of 3.5 to 5.0 mm can effectively absorb a collision. At the same time, unnecessary overdimensioning of the buckling elements, preferably in the form of a buckling plate, and thus of the entire vehicle barrier is avoided. In particular, it has been found that a thickness of 4.0 mm for a buckle plate is sufficient to meet the current requirements for vehicle barriers without there being an undesirably heavy version of the vehicle barrier according to the invention.
    In an advantageous preferred embodiment according to the present invention, the buckling element is provided with a connecting element for connecting the buckling element with a profile.
    By providing a connecting element, a preferably releasable coupling or connection can be established between the kink element, preferably in the form of a kink plate, and the profile. A further advantage of such a connecting element is that such an element distributes the forces exerted on the profile as optimally as possible over the entire buckling element. Such a connecting element is, for example, designed in the form of a bracket which is connected with bolts to the profile and to the kink element.
    In an advantageous preferred embodiment according to the present invention, a diagonal is provided between two buckling elements.
    By providing a diagonal between two buckling elements, preferably between two adjacent buckling elements, it is achieved that the entire vehicle barrier is provided with an extra rigidity and / or stability. The diagonal is herein preferably provided as a strip or rod that can absorb a tensile load. Due to the extra stiffness and / or stability realized by the diagonal, the vehicle barrier according to the invention can be made lighter in comparison with known vehicle barriers. It has been found that a mass of 40 to 50 kg per linear meter length for the vehicle barrier according to the invention, and in particular about 44 kg per linear meter length of vehicle barrier, is sufficient to meet all applicable requirements for such vehicle barriers.
    A diagonal is preferably provided every six to twelve buckling elements. Experimentally it has been found that, in particular every nine buckling elements, the provision of a diagonal on the one hand makes a significant contribution to the rigidity of the entire vehicle barrier, and on the other hand leads to a limited amount of parts, mass and assembly work for such a vehicle barrier.
    By arranging a diagonal around the nine elements, it is effectively ensured that a diagonal is provided around every length of approximately twelve meters.
    Preferably, the diagonal extends from the upright to the profile, viewed in the normal driving direction of a vehicle, over a road along which the vehicle barrier is placed. By providing the diagonal in this configuration, the diagonal is optimally loaded on occurring tensile loads, and thus optimally utilized with regard to the rigidity for the entire vehicle barrier at. a collision of, for example, a vehicle. Preferably, in this configuration use is made of a combination of the above-mentioned measures in order to thereby use the diagonal as optimally as possible for achieving an effective and efficient vehicle barrier.
    In a further advantageous preferred embodiment according to the present invention, the uprights are connected with an additional profile.
    By connecting the posts to each other with an additional profile, extra stability is obtained for the vehicle barrier according to the invention. The vehicle barrier becomes even stiffer in construction, since any applied force is better distributed over several posts. The additional profile herein preferably comprises a U-profile. Also preferably this profile is connected to the upright by means of a bolt connection. This ensures that undesired torsion of the uprights, which are often designed as a C-profile, is prevented as much as possible in the event of an occurring load of the vehicle barrier. By preventing the torsion, the vehicle barrier is efficiently used if there is a load, such as a collision of a vehicle with the barrier.
    The present invention further relates to an obstacle protector comprising a vehicle barrier as described above.
    Such an obstacle protector has the same advantages and effects as described for the vehicle barrier. Such an obstacle protector can, for example, be placed in specific traffic situations, for example for securing lamp posts, traffic lights, etc.
    Furthermore, such an obstacle protector provided with a vehicle barrier as described above can be used for securing a tank, silo or corner of a building at, for example, industrial sites.
    The present invention furthermore also relates to a method for turning a vehicle and / or protecting an obstacle, comprising providing a vehicle barrier as described above.
    The method according to the invention has the same effects and advantages as described for the vehicle barrier and obstacle protector.
    Further advantages, features and details of the invention are elucidated on the basis of preferred embodiments thereof, wherein reference is made to the accompanying drawings, in which: figure 1 shows a view of a vehicle barrier according to the invention; figure 2 shows a side view of the barrier from figure 1; figure 3 shows a detail of the barrier from figure 1; figure 4 shows a top view of a section of the barrier from figure 1 with diagonal; and - figure 5 shows a view of the section from figure 4. A vehicle barrier 2 (figure 1) is provided with a number of uprights 4 and profiles or boards 6. A board 6 is connected to the upright 4 by means of a number of buckling plates 8. In the embodiment shown, upright 4 is a C-profile. The upwardly directed ends of uprights 4 are mutually connected with a U-profile 10. The other end of upright 4 is placed in the ground 12. Kering 2 is provided next to a road 14 and extends in the usual direction of travel A on the road 14.
    In the embodiment of barrier 2 shown, shelf 6 is connected to buckling plate 8 (figure 2) with the aid of a bracket 16. Bracket 16 serves for fixing board 6 to buckle plate 8 and additionally has the function of distributing any forces occurring on boards 6 as completely as possible over buckle plate 8. Bracket 16 is releasably connected to buckle plate 8 by means of bolt connections 18. in the embodiment shown, board 6 is also directly connected via bend 16 to buckling plate 8 at a position approximately halfway up the height of profile 6 with the aid of bolt 20. Buckling plate 8 has a length extending between upright 4 and board 6 of such 40 cm. Furthermore, buckle plate 8 at the position of upright 4 is releasably attached thereto by means of bolt connections 22.
    The upper end of upright 4 is connected to U-profile 10 via bolt connection 24 (figure 3). Two adjacent ü-profiles 10 are releasably connected to each other with the aid of a coupling 26 (Figure 2) with bolt connections 28. Two adjacent boards 6 are releasably connected to each other by means of a small overlap, at the location of which a rejuvenation of boards 6 is provided, with the aid of bolt connection 32.
    In the embodiment shown, a diagonal 30 (figures 4 and 5) is provided between about 12 meters, or every nine buckle plates 8, between two adjacent buckle plates 8, which extends in the usual direction of travel A from a post 4 to shelf 6. The part of barrier 2 here forms between two adjacent kink plates 8 one section provided with a diagonal 30. In order to realize a simple and efficient assembly, one of the two kink plates 8 is provided with a diagonal 30 for realizing a simple and efficient mounting. placed in a mirrored state. This further limits the number of assembly operations, as well as the number of different parts required. The diagonal 30 is preferably tensile to load, thereby further strengthening the barrier 2.
    Barrier 2 can be provided next to a road 14, and also next to a building or other obstacle, such as a lamppost, traffic sign, or liquid tank. Such an obstacle protector is provided in the same manner as barrier 2 shown in figures 1-5.
    In the embodiment shown, the buckling plates are provided with a thickness of 4 mm, average mass of 44 kg per linear meter of barrier 2, and in the embodiment shown the various profiles for shelves 6, uprights 4 and profiles 10 are provided with galvanized steel.
    When a barrier 2 is placed, uprights 4 are placed in a base 12. Then, buckle plates 8, U-profiles 10 and also boards 6 are releasably secured thereto by means of brackets 16 with bolt connections 18, 20, 24, 28, 32. At a possible replacement of a part of the retainer 2, the aforementioned bolted connections can be loosened as far as necessary, the relevant parts replaced, and subsequently re-tightened. The replacement of parts will in many cases relate to boards 6 and buckle plates 8. Only with relatively heavy loads as a result of, for example, a collision, some uprights 4 could or should also be replaced.
    In the event of a load on the vehicle barrier or obstacle protector 2, an object such as a vehicle will come into contact with, in the first instance, the boards 6. The forces occurring, inter alia as a result of brackets 16, are distributed over a number of buckle plates 8 and also also over the entire buckle plate 8. As a result, a large part of the occurring load is absorbed. The U-profiles 10 used prevent torsion of uprights 4, so that a force can also be absorbed with this if buckle plates 8 are found to be unable to do this alone. In this way, the complete barrier 2 contributes to absorbing an occurring load.
    Tests 2 conducted as shown in Figures 1-5 have demonstrated their efficient and effective operation.
    In a first test, a passenger vehicle with a speed of about 100 km per hour at an angle of incidence of 20 ° with a weight of 867 kg was brought into contact with a barrier 2. It has been found that the deformation of barrier 2 is limited to boards 6 and bending plates 8.
    In a second test, a bus with a speed of about 73 km per hour at an angle of incidence of 20 ° with a weight of 12840 kg was also brought into contact with a barrier 2. It has been found that even with this large load of barrier 2 torsion of uprights 4 was prevented, among other things, by the use of U-profile 10.
    Both experiments demonstrate the proper functioning of barrier 2, such that all requirements are met. In particular, it has been found that barrier 2 meets the currently strictest requirements in this area. An extremely good optimum has thus been obtained between good protection on the one hand and an effective, efficient and user-friendly barrier 2 on the other.
    The present invention is by no means limited to the above described preferred embodiments thereof. The requested rights are determined by the following claims within the scope of which many modifications are conceivable. For example, it is possible to provide barrier 2, in whole or in part, from a material other than galvanized steel. For example, the use of plastic materials is possible.
