Abstract
An improved shoring frame adapted by a unique design to utilize relatively thin-walled aluminum tubing with a reasonable load-rating, be easily manufactured, and be compatible with existing steel accessories; where the extruded aluminum legs are each generally circular with a longitudinally-extending flattened portion for attaching struts and studs, and preferably having at least two internal ribs, circumferentially symmetrically-spaced relative to said flattened portion axially to contain accessories such as existing jack screws, extension legs, U-head fixtures, and the like.
