摘要： 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 (or channeled load collars) fastened through pairs of locating holes (or dual slots) spaced along each extension frame leg. The locating holes (or slots) 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).
