Claim 1

Support apparatus for residing on apparatus support members, comprising: a pair of oppositely disposed metal channel members spaced a predetermined distance apart in the horizontal direction and extending a predetermined distance in the horizontal direction, each of said channel members being of generally E-shaped crosssectional configuration and including a plurality of integrally formed and horizontally disposed flanges aligned vertically and spaced apart vertically predetermined distances, said flanges providing said channel members with resistance to bending in the horizontal direction, the flanges formed on each channel member extending towards the flanges formed on the other channel member, the lower two flanges on each channel member for receiving the ends of metal joists therebetween, and the upper and lower flanges on each channel member defining the top and bottom of said channel members; a plurality of vertically disposed metal joists spaced apart predetermined distances in the horizontal direction and extending between said channel members and perpendicular thereto, the ends of said joists being received between said lower two flanges formed on said oppositely disposed channel members, whereby said joists are supported upwardly of the bottoms of said channel members and whereby said bottoms of said channel members define the bottom of said support apparatus and whereby upon said support apparatus residing on said apparatus support members only said bottoms of said channel members engage said apparatus support members and said joists are elevated above said apparatus support members, and said joists being fixedly secured to said channel members; a plurality of metal deck members spaced apart a predetermined distance in the horizontal direction and said deck members extending a predetermined distance in the horizontal direction and parallel with said channel members, said deck members residing on said joists, each of said deck members being of generally -shaped cross-sectional configuration and including a horizontal member for receiving a load applied vertically downwardly to said support apparatus and said horizontal member having a plurality of integrally formed and vertically disposed and downwardly extending legs for providing said deck member with resistance to bending in the vertical direction but allowing some deflection downwardly of said deck members upon said load being applied thereto directly over said legs, and the bottoms of said legs of said deck members being fixedly secured to the tops of said joists, the outer portion of the horizontal members of said outer deck members extending over said tops of said channel members whereby said load can be applied directly only to said deck members and upon said load being applied to said deck members directly over the tops of said channel members, said outer portions of said deck members providing at least some deflection downwardly; said pair of channel members for providing said support apparatus with resistance to bending in the vertical direction; and said joists for providing said support apparatus with resistance to bending in the vertical direction and upon said load being applied to said deck members directly over the points at which said legs of said deck members engage said joists said joists providing at least some downward deflection due to said elevation of said joists above said apparatus support members by said bottom flanges of said joists.
