Definitions

the present invention relates to a vehicle restraint system for securing roadways having a wall structure comprising a plurality of weft-like wall elements extending along the roadway to be secured, and a plurality of anchoring devices for fixing the wall elements to a ground.
the vehicle restraint systems can be assigned to different safety categories. Serve for this purpose parameters that are determined by experiments.
One of these parameters is the so-called “stoppage stage”, which provides information about how high the stoppage capacity and the suitability for deflecting an impacting vehicle of the respective vehicle restraint system.
Another parameter is the so-called “effective range”, which is calculated from a dynamic transverse displacement in the event of an impact and the actual width of the vehicle restraint system.
a parameter termed "impact severity level” is used to estimate the load on vehicle occupants and, therefrom, an expected severity of injury upon impact of the vehicle with the vehicle restraint system.
a vehicle restraint system of the type described above for securing roadways with a wall construction comprising a plurality of weft-like composite wall elements extending along the roadway to be secured, and a plurality of anchoring devices for fixing the wall elements to a substrate is that the wall elements each have a grid structure with intersecting struts.
the present invention again proposes to use wall elements made of a deformable material.
These wall elements are designed with a grid structure composed of intersecting struts.
a lattice structure also referred to in the jargon as "grating”
grating has a certain deformability, wherein the lattice structure in the form of cross-webs crossing struts has a high retention capacity, because the struts act like a safety net for an impacting vehicle.
the individual struts function as a plurality of tensile elements, both in the longitudinal direction (parallel to the road surface) and in the transverse direction (height direction).
the lattice structure is formed of intersecting struts, preferably of metal, plastic, fiber-reinforced plastic or plastic with filling material. Depending on the application situation, certain materials are preferred here.
a development of the invention provides that the metal struts are aligned with a depth dimension transverse to the direction of travel of the road.
the retention capacity, the deformation capacity and the effective range in accordance with the dimensioning of the metal struts in the depth can be set transversely to the direction of travel of the road.
the deformation depth decreases with greater depth, higher impact energies can be absorbed.
the range of action can also be reduced.
this polygonal, rectangular or square mesh has. It is possible that the polygonal or rectangular meshes have a greater longitudinal extent in the direction of the road.
the mesh size is again selected depending on the application situation. A smaller mesh size increases the retention capacity and reduces the deformation capacity.
the range of influence can also be influenced by a suitable choice of the anchoring devices.
an anchoring device that is firmly anchored to the ground, that is immovable.
at least one of the anchoring devices is slidably mounted on the ground.
at least one of the anchoring device can be pressed against the ground via a clamping strip or a clamping frame. It is possible that the individual anchoring devices Rubber mats are pressed against the ground so as to increase the friction between the ground and sliding anchoring device.
At least one of the anchoring devices has a pair of uprights which can be attached upright to the ground, between which at least one of the wall elements can be fixed. It is possible that the spars are plate-like.
a development of the invention provides that adjacent wall elements are fixed together, preferably screwed together.
a guide profile running along the roadway to be mounted on the side of the wall elements facing away from the substrate. Also this over several wall elements away extending guide profile ensures a connection of the individual wall elements with each other and thus for an increase in the retention capacity.
the guide profile has a greater width across the roadway, as the wall elements.
FIG. 1 an inventive vehicle restraint system is shown and generally designated 10.
This comprises a plurality of wall elements 12, 14, 16 which are composed in the manner of a weft and which have longitudinal struts 18 and transverse struts 20 running parallel to the longitudinal direction of the roadway.
the individual wall elements 12, 14, 16 are screwed to one another on facing end side struts 22, 24 via connecting bolts 26.
the vehicle restraint system anchoring devices 28, 30, 32 with which it is attached to a substrate U.
a guide profile 34 is provided, which surrounds the upper portion of the wall elements 12, 14, 16.
each wall element 12 and 14 each having a square lattice structure formed by the longitudinal struts 18 and the cross struts 20 with a grid width d, are via fastening bolts 26, washers 40 and nuts 42, in corresponding receiving openings 44, 46 at the end faces of the respective Wall elements 12 and 14 are inserted, screwed together.
On top of each guide rails 34 are mounted in the form of a handrail.
the anchoring device 30 has a frame 50 which is bolted to the substrate U via fastening bolts 52.
the frame plate-like spars 52, 54 are accommodated, which are displaceable in the frame 50.
An upper region 56 or 58 of these spars is aligned substantially perpendicular to the substrate U. Starting from this upper region 56 or 58 extends to this slightly angled transition region 60 and 62, which merges in a substantially parallel to the ground extending foot region 64 (for the spar 52).
transition slots 66 are provided, with which the spars 54, 52 are guided in the frame 50.
a wall element 12, 14, 16 is clamped via fastening bolts 70 with corresponding washers 72 and nuts 74 between two mutually opposite spars 52, 54 and thus in an upright position, as in FIGS. 1 and 2 shown kept.
the frame 50 is pressed onto the ground.
the foot portions 64 of the spars are also pressed against the ground.
the frames are dimensioned with a receiving area 76 such that a corresponding pressing of the foot portions 64 on the substrate U is possible.
rubber mats are arranged, which increase the coefficient of friction between the ground and foot section.
FIG. 5 shows the anchoring device 28 in partial view. It can be seen in the frame 50, and the raised recess 82 in which the two plate-shaped bars 52, 54 are slidably received.
the two arrows P 1 and P 2 show the possibility of clamping the wall elements between the upper sections 56, 58 of the two spars 52, 54.
the frame 50 is prefabricated, for example, welded.
FIG. 6 shows an alternative embodiment in which the frame 90 is composed of several flat iron.
Two flat iron 92 serve as a support on the ground.
Two parallel flat iron 94 with greater width extension than the flat iron 92 form, so to speak, the guide area for the spars 52, 54 and cooperate with the corresponding slots 66.
Below this flat iron 94 are the foot sections.
two transversely extending flat iron 96 are still provided, which form the frame structure.
FIG. 7 shows a first embodiment of a grid 12 with square grid structure.
the width of the grid mesh is constant in the longitudinal direction and in the height direction and denoted by d.
FIG. 8 one recognizes, however, an alternative embodiment for a wall element 12 ', in which a rectangular grid structure is present, wherein in the longitudinal direction, the mesh size is about 2d, that is twice the grid width in the height direction.
width extension b of the lattice structure Furthermore, one recognizes in the two FIGS. 7 and 8 also the width extension b of the lattice structure.
the present vehicle restraint system offers the following advantages: Due to the displaceability transverse to the roadway, which provides the individual anchoring devices, already a part of the impact energy can be reduced by simply shifting under friction. The resistance, which is opposed to such a shift, determined in accordance with the clamping force with which the anchoring devices are clamped against the ground. A corresponding deflection is indicated by the dashed line in FIG. 4 played.
the vehicle restraint system according to the invention also has a deformation capacity. The lattice structure of the individual wall elements can be deformed more or less depending on the impact energy, the strength of the individual struts, that is, the dimensioning in the width direction (see FIGS.
Parameter b) is decisive for the deformation capacity.
the net-like structure provides good retention properties while still having a pronounced deformability, so that the disadvantageous effects of a rigid system, such as a vehicle restraint system made of concrete elements described at the outset, do not occur.
a rigid system such as a vehicle restraint system made of concrete elements described at the outset
it has an advantageous effect that the grid structure causes strong friction even when in contact with a vehicle surface, and thus the vehicle is braked.
the system consists of a substantially vertical wall, there is also no ascent of the vehicles, such as concrete elements on the slope of the well-known New Jersey profile. Also, this system does not have a post, such as conventional guard rail systems, which regularly cause a vehicle to become wedged and abruptly decelerated becomes.
the anchoring devices have evasion capability.
