Abstract
Abstract A structural unit, such as for instance a storage framework composed of a plurality of storage frame components assembled into a storage rack, for use, for example, in warehousing systems. The framework comprises generally vertical column members which in certain embodiments are basically of a generally U-shaped configuration in horizontal cross section, but having a connecting or bridging plate or member disposed between and connected to the arms of the U, with the bridging member being preferably recessed inwardly from the distal ends of the arms. A fastener means, such as for instance a threaded stud, is secured to the bridging plate and projects generally perpendicularly outwardly therefrom. In other embodiments the column members are tubular and of polygonal configuration in horizontal cross section with the studs secured to spaced plates attached to one face of the respective column. Laterally extending connecting assemblies including load carrying means, are connected to and spaced vertically along the columns, and define the storage volumes in the storage rack. The connecting assemblies include vertically elongated end members having an opening therethrough through which is received a respective stud. In certain embodiments the end members are adapted to be deformed or prestressed upon tightening actuation of an associated fastener such as for instance a threaded nut, on the stud, thereby enhancing the rigidity of the connection at the fastener. One advantage of this arrangement over prior art is that generally standard structural components can be utilized in the formulation of the framework rather than requiring the necessity of substantial amounts of custom made components, and mass production of the framework components is facilitated. A method of eliminating the need for diagonal bracing in the ladders of the storage framework is likewise disclosed, and in a manner whereby the diagonal integrity of the load supporting assemblies of a storage rack is maintained.
