Claim 0:
1. A universal prop system for a grid shoring system for building construction, comprising:
a plurality of interchangeable prop stands;
a plurality of interchangeable stringer jacks;
a plurality of interchangeable drop heads, each drop head for removably interconnecting a selected one of the interchangeable prop stands with a selected one of the interchangeable stringer jacks, each drop head further comprising a drop seat defining a bottom rail interface to removably support a bottom rail of the grid shoring system, wherein the bottom rail in an upper bottom rail position supports a lower concrete form supporting lower wet concrete while the lower wet concrete sets, and wherein the bottom rail in a lower position facilitates removal of the lower concrete form after the lower wet concrete sets;
wherein each drop seat is selectively movable between an upper drop seat position and a lower drop seat position to move the bottom rail between an upper bottom rail position and a lower bottom rail position; and
the variety of stringer jacks each comprise a threaded rod, a threaded collar movably captured on the threaded rod, and a stringer head connected to the threaded rod to support a top rail of the grid shoring system;
wherein each stringer jack telescopically interconnects with a selected drop head to selectively move the stringer head with respect to the selected drop head between an upper stringer head position and a lower stringer head position in response to rotation of the threaded collar to move the top rail between an upper top rail position and a lower top rail position, wherein the top rail in the upper top rail position supports an upper concrete form supporting upper wet concrete while the upper wet concrete sets, and wherein the top rail in the lower top rail position facilitates removal of the upper concrete form after the upper wet concrete sets.
