ABSTRACT:
A shoring system having base frames with legs preferably of extruded aluminum in oval cross-section (for optimal support with minimal use of materials) and optionally having three T-slots formed integrally therewith and extending the length thereof (for versatility in bracing), and preferably in combination with telescoping extension frames formed of extruded aluminum and adjustably inter-connected with respective uppermost base frames by U-pins fastened through dual locating holes spaced in pairs along each extension frame leg. The dual locating holes are formed in thickened walls on either side of a central hollow core in each extension frame leg (to accommodate retraction of a jack screw mounted on the leg).
