Abstract
A resiliently mounted and constructed rigid floor grate assembly is disclosed, in which a series of metallic tread rails of T-shaped cross section, placed side by side and connected by tie rods, are separated by individual, resilient spacing and supporting elements. The spacing and support elements are placed between each pair of tread rails, underneath the tread portions thereof, and are held under compression by the tie rods to form a rigid assembly. In addition, the height of the spacing and support elements is slightly greater than the height of the vertical web portions of the tread rails, to support the metallic elements slightly above the hard surface of a floor recess in which the grate assembly is placed. Significantly reduced metallic noise and clatter is an important benefit.
