High-capacity beam and modular grid shoring systems

A modular grid shoring system comprising a set of interoperable modular grid shoring system components including high-capacity beams for supporting a nominal 13-inch thick concrete platform and low-capacity beams for supporting a nominal 6-inch thick concrete platform, joists and drop heads, each low-capacity beam comprising a pair of conformant interface portions extending in a longitudinal direction on opposing sides of the low-capacity beam, each conformant interface portion defining a conformant interface rail configured for receiving conformant end caps supporting respective joists extending in a transverse direction, each conformant interface portion further comprising a pair of conformant end caps attached to and substantially filling a frontal end face of a respective conformant interface portion, each low-capacity beam further comprising a low-capacity truss portion extending from a bottom side of the conformant interface portion, each high-capacity beam comprising:

• a pair of conformant interface portions extending in a longitudinal direction on opposing sides of the high-capacity beam;
• each conformant interface portion defining a conformant interface rail configured for receiving conformant end caps supporting respective joists extending in a transverse direction;
• each conformant interface portion further comprising a pair of conformant end caps attached to and substantially filling a frontal end face of a respective conformant interface portion;
• each high-capacity beam further comprising a high-capacity truss portion extending from a bottom side of the conformant interface portion;
• wherein the high-capacity beams are adapted for interoperability with the low-capacity beams, joists and drop heads interoperable with the low-capacity beams;
• wherein a nominal 8-foot lengths of the high-capacity beam weighs less than about 50 lbs.;
• wherein each high-capacity beam is adapted for supporting a nominal 13-inch thick concrete platform in a grid shoring assembly comprising nominal 8-foot lengths of the high-capacity beam extending in a longitudinal direction supporting nominal 8-foot joists extending in a transverse direction with no more than one quarter-inch vertical deflection.
