<p>The plate (3) has an upper side formed with a supporting surface (13), where the plate is made of plastic material. An abutment surface is formed on an end side of the plate, and extends in longitudinal direction of the plate. A reinforcing rib (21) is formed at the upper side of the plate, and rises up beyond the supporting surface and extends transversely to the abutment surface. A bottom part of the plate is formed with an aperture extending into a region of the plate in which the reinforcing rib is formed.</p> |
