Abstract:
1. A coupling system for vertically engaging support columns for concrete multi-floor construction, the system comprising: a) a plurality of slab support column assemblies; b) each slab support column assembly having a main support pipe, each main support pipe includes a threaded cavity at the top end thereof and a smooth recess at the bottom end thereof, each main support pipe having a skeletal framework disposed at a top portion thereof, each said skeletal frame work supporting a pair of form slabs; c) a coupling for connecting a subjacent main support pipe to a superadjacent main support pipe in a secure manner, said coupling comprises a threaded male projection at a bottom end and a smooth finish pin extending from a top end, said threaded male projection and said smooth finish pin are dimensioned to mate with said threaded cavity and said smooth recess respectively; and d) a spacer element positionable about the threaded male projection of the coupling for providing spacing between said subjacent main support pipe and the coupling, said spacer element is a pair of wedge shaped shims with each shim having a semi-circular cutout disposed on a narrow edge thereof dimensioned to encompass said threaded male projection.
