Abstract
A system for providing re-usable safety support fences and fall restraints for the construction industry. The system comprises a plurality of disposable bases which are welded to I-beams or otherwise permanently attached to a floor or roof, and a plurality of removable support posts that screw into the disposable bases. The support posts form the posts of a safety fence through which steel cables are threaded to form a fence. Also, a fall arrestor, comprising an eye hook onto which a construction or maintenance worker on the perimeter of a building may attach, can be screwed into the permanently mounted disposable base. Additional embodiments for use with concrete construction instead of steel I-beams are disclosed.
Claims21
A reusable modular system for fall restrain support and fall arrest of individuals comprising:
- a) at least one disposable base permanently attached to an I-beam, a floor or a roof, comprising
- a C-channel with a generally horizontal top portion and two downwardly extending vertical flanges, defining an inner surface between the vertical flanges and an outer surface, the C-channel defining a vertical bore extending through the top portion from the outer surface to the inner surface;
- a top nut with an upper threaded bore welded to the top portion on the outer surface in a position wherein the upper threaded bore and vertical bore are substantially coaxial;
- and,
- a bottom nut with a lower threaded bore welded to the top portion on the inner surface in a position wherein the lower threaded bore is substantially coaxial with the vertical bore and upper threaded bore;
- b) at least one re-usable post having a vertical height comprising a threaded cylindrical bottom portion configured to mate with the upper and lower threaded bores;
- wherein the at least one re-usable post is rigidly removably engaged with the at least one disposable base in a substantially vertical position by mating the threaded cylindrical bottom portion with the upper and lower threaded bores such that the re-usable post can be disengaged from the disposable base as desired.

- a C-channel with a generally horizontal top portion and two downwardly extending vertical flanges, defining an inner surface between the vertical flanges, an outer surface, and a vertical bore extending through the top portion from the outer surface to the inner surface;
- a first nut defining a threaded bore permanently fixed to the top portion substantially coaxial to the vertical bore;
- and,
- at least one re-usable post having a vertical height comprising a threaded cylindrical bottom portion configured to mate with the threaded bore;
- wherein
- the at least one re-usable post is rigidly removably engaged with the at least one disposable base in a substantially vertical position by mating the threaded cylindrical bottom portion with the threaded bore such that the re-usable post can be disengaged from the disposable base as desired.
