Grain bin floor support system

For use with a storage bin for storing grain or the like, an improved floor support system comprising a plurality of flooring elements jointly cooperable for providing a generally horizontal grain bin floor and a plurality of independent floor supports arranged in an assembly for supporting said floor, each floor support comprising a curvilinear lower rail serving as a base member formed for bearing against a supporting surface and defining thereon a curvilinear path, an upper rail member of curvilinear configuration like that of said lower rail, a plurality of load bearing spacers extending between said lower and upper rails for maintaining the latter in spaced, parallel relationship, said upper rail bearing against and contacting said flooring element in a curvilinear path coincident with the curvilinear path defined on said supporting surface, said spacers transmitting load from said upper rail to said lower rail, said floor elements comprising sheets of flooring material having offset flanges along the sides thereof for providing an interfitting relationship with similar of other sheets of flooring material, said flanges being each downwardly offset from the plane of said sheets of material for defining a downwardly extending channel of box-like girder form between each two sheets of flooring material for being engaged by an upper rail of the respective floor supports, said channels being parallel and evenly spaced apart across the width of said floor, said upper rail having a plurality of upstanding vertical web sections spaced at intervals along at least portions of at least one edge of said rail, the height and spacing of said vertical web sections along said rail being such that said sheets of flooring material are supported by engagement of the upper rail against said box-like girders, and said vertical web sections are positioned between said box-like girders, said vertical web sections increasing in length from the center of said floor support upper rail toward its outer extremities, the spacing along said upper rail between adjacent vertical web sections corresponding to, and being slightly greater than, the width of each said box-like girder, whereby a secure interfitting relationship between said girders and said floor supports is attained, and whereby a plurality of said girders are supported by a single floor support but along said curvilinear path thereby to effectively increase the area of support provided by each floor support.
