Abstract: A high-capacity beam includes interoperable features conformant with the pretexting modular grid shoring system including conformant interface rails and conformant end caps that removably engage with the conformant interface rails. The truss portion of the high-capacity beam has the same width and a greater height compared to the truss portion of the low-capacity beam. The high-capacity beam may also include a conformant T-slot and beveled end faces on respective opposing sides of the high-capacity truss portion. A nominal 8-foot length of the modular high-capacity beam weighs less than about 50 lbs., while a nominal 6-foot length of the low-capacity beam weighs less than about 40 lbs. A grid shoring assembly utilizing the high-capacity main beams is rated for supporting a nominal 13-inch concrete platform, while a grid shoring assembly utilizing the low-capacity main beams is rated for supporting a nominal 6-inch concrete platform.

Abstract: A universal prop system for grid shoring provides increased versatility and cost effectiveness over conventional grid shoring systems for building construction, such as concrete parking garage construction. The universal props include a variety of interchangeable prop stands, interchangeable drop heads, and interchangeable stringer jacks with a variety of different types of stringer heads. The interchangeable drop heads interconnects the interchangeable stringer jacks with the interchangeable prop stands. The interchangeable drop heads are designed to support a variety of different types of rails, such as beams, joists, rafters, pipes, etc. The interchangeable stringer jacks include a number of different stringer heads configured to support a variety of different stringers. The different stringer heads include, for example, U-heads, spindle forks and jack plates, with and without detachable threaded shafts.

Abstract: A pass-through head assembly is provided. The pass-through head assembly may include a central shaft, a plurality of support bars, a seat, and a seat support plate. The central shaft may extend between a first end plate and a second end plate. Each end plate may define an aperture that aligns with an interior cavity of the central shaft. The plurality of support bars may extend from the central shaft and the second end plate. The seat and seat support plate may each be circumferentially disposed about the central shaft and define apertures that are sized to allow the seat and the seat support plate to pass over the central shaft and the plurality of support bars. The seat may be configured to support one or more beams. The seat support plate may be disposed between the seat and the second end plate.
