Furthermore, a guard rail 6 is fastened to the lower longitudinal beam 5 on the carriageway side. The end face of the guardrail 6 projects horizontally beyond the end face of the upper longitudinal spar 4.

• the protective plank arrangement in the event of an impact, for example by a vehicle, is deformed in such a way that the deformation profile 3 is first pressed in at the lower end 18 without the stand behind it being affected is pulled. If, in addition, the deformation profile 3 is pressed in completely in the lower region 18 due to the impact, the force is transferred to the stand 2 located behind it. In this position, the end face of the guardrail 6 and the end face of the upper longitudinal spar 4 lie almost in one plane (see reference symbol VE in FIG. 6c).
• Known guardrail arrangements of this type are particularly intended to prevent the vehicle from crossing the edge of the carriageway.

• the upper longitudinal spar is supported on a floor anchor via an obliquely downwardly extending support profile, ensures that not only a stabilizing The guardrail is fixed over the uprights, but also a stabilization in the form of a tensile stress occurs within the upper longitudinal spar and the support profile, which counteracts the application of force.
• the guardrail is fastened on the back via a support bracket.
• the outer legs of the guardrail can be supported in order to increase the rigidity of the guardrail itself. This also leads to material savings with regard to the guardrail.
• This support or increase in the rigidity of the guardrail is achieved in a simple manner according to claim 3 by the fact that the support bracket has essentially the shape of a C-profile with legs opening outwards and the ends of the legs are only on the Support the angled end of an optionally specially designed guardrail profile.
• the protective plank arrangement can be realized in a simple manner by stands with a C cross-sectional profile, the lower and upper longitudinal spar being screwed to the stand on one leg of the C cross-sectional profile.

• the rectangular profile is connected to the stand by means of a pressure plate, the force transmission is increased, and in particular when the pressure plate is non-positively connected to the stand.
• the pressure plate is formed in one piece with the guide and spacer element, so that the number of components of the guard rail arrangement per stand is kept to a minimum. If the lower longitudinal spar is welded at the end to the support profile, this ensures that the overall construction is more stable. A tensile stress of the lower longitudinal spar which supports the resistance of the guardrail arrangement and which is caused by the interaction of several uprights also contributes to the stability of the overall construction.
