  • FIGS. 5 and 6 the plan view and the side view of a possible embodiment of the recess body 38 are shown.
  • This consists essentially of a cuboid block of a resilient, elastic or elasto-plastic material.
  • the recess body 38 has an open-edged recess 39, so that it can be pushed around the deformation element 31. When installed, the recess body 38 forms a bedding of the free length of the deformation element 31, whereby the load capacity of the deformation element 31 is increased.

  • the maximum load occurs on the supporting element 2 opposite the impact and there on the rear end viewed in the direction of travel. If the connection between support element 2 and concrete wall element 1 is formed only by means of anchoring elements 3 without free length, then the edge-outermost anchoring element 3 is so heavily loaded with a sufficient impact energy that it is sheared off.

Furthermore, the load is absorbed by tension bands 17 and the adjacent concrete wall elements 1. It is therefore constructive for the deformation element 31 to ensure that it can deform so far without fail until other elements absorb the load. In this case, a plastic deformation of the deformation element 31 may be provided.
  • the recess body 38 increases the load capacity of the deformation element 31 and also prevents the deformation element 31 from starting to oscillate.
  • the deformation element 31 prevents that the support element 2 can protrude partially from the concrete wall element 1.
  • the edge-outermost anchoring elements 3 it seems to be particularly expedient to design the edge-outermost anchoring elements 3 as deformation elements 31, since then the distance between the edge of the support element 2 and the deformation element 31 is minimal.
  • another anchoring element 3 is formed in the edge region of the support element 2 as a deformation element 31, wherein first fail the outermost anchoring elements 3 under load and only then the deformation element 31 begins to deform.
