Abstract

A surface plate (100) for supporting generally planar loads, specifically mine roofs. Surface plates in accord with the preferred embodiments of the present invention comprise a plurality of embossments (108, 112, 116). The embossements provide the surface plates with increased strength when compared against the prior art. In the preferred embodiments, one of the plurality of embossments is a continuous perimeter embossment (112) that generally parallels the outer perimeter of the surface plate. Another of the plurality of embossments (116) is a circular embossment located at the center of the surface plate wherein a central opening (120) through which a mine roof bolt is received is located. The preferred embodiments may further comprise a plurality of radial embossments (108) that extend from the central embossment to the perimeter embossment. One embodiment is rectangular in shape, four radial embossments intersect and extend from the central embossment towards the perimeter embossment and intersect with the perimeter embossment.
