- the vehicle restraint system on roads serves to restrain impacting vehicles and may further be referred to as a baffle.
- the vehicle restraint system is provided for installation following a predeterminable course, wherein the vehicle restraint system follows the course of the road, the lane course, the construction site course or the like.
- the tension element is provided for the continuous arrangement in the guide wall, in which the tension element extends continuously from a first end wall of the guide wall element to a second end wall of the guide wall element.
- a first fixing element of the two fixing elements penetrates the first end wall and / or protrudes from the first end wall.
- a second fixing element of the two fixing elements penetrates the second end wall and / or protrudes from the second end wall.
- the two fixing elements are connected to each other by means of elongated reinforcing bars or reinforcing ropes, ie by means of elongated reinforcing elements.
- first ends of the reinforcing elements on the first fixing element and second ends of the reinforcing elements on the second fixing element are permanently connected securely in position.
- the reinforcing elements and the fixing elements may in particular be welded together.
- the reinforcement elements can also be referred to as reinforcements.
- the conventional tension member comprises four, six or eight reinforcing elements.
- the disadvantage here is that the steel price represents an enormous cost factor in the production of the Leitpointemente and is subject to strong fluctuations, with price spikes in the price of steel can not be excluded.
- the disadvantage here is that in the conventional arrangement of the reinforcing elements, the guide wall element has a predetermined first minimum wall thickness, since at a particularly low Wall thickness of the baffle element this has no sufficient stability in the event of impact.
- the object of the invention is therefore to provide a tension element of the type mentioned, with which the baffle element with less dependence on the metal price, especially steel price, is inexpensive to produce and which the formation of a
