Definitions

  • the present invention relates to a mounting rail according to the preamble of claim 1 and a building or a building component according to the preamble of claim 12.
  • Anchor rails or mounting rails are poured or embedded in the construction technique in concrete, so that only an upper side or an outer region of a supporting profile of the mounting rail is freely accessible.
  • the mounting rail initiates the forces introduced into it by a contact or a connection with the surrounding concrete in the concrete.
  • the mounting rail has generally backward anchor. Centrally attacking forces are generally introduced essentially by the anchors in the concrete. Transverse forces acting on the anchor rail are introduced into the concrete by lateral limbs of the supporting profile of the mounting rail. In the case of large transverse forces, cracks occur and, as a result, a broken block on the concrete. The cracks spread out at different angles in the concrete, with the angle increasing the volume of the broken fragment and thus the pull-out force. It thus occurs at shear forces on a relatively early failure of the mounting rail due to a shallow crack or a small broken clod.
