Box shaped base plate for e.g. industrial halls has edge protection along contact surface whereby edge protection has deformation, provided between disk upper and lower surface, which is concave and one piece in disk

摘要

The base plate has an edge protection (3) along the contact surface (6) whereby edge protection has deformation (7), provided between the disk upper surface (4) and lower surface (5), which is concave and one piece in the disk. Shanks (8,9) are connected for the deformation congruently to the base (10) parallel to the edge protection. An independent claim is also included for the connecting element.
