Abstract:
A drophead nut for use with formwork building components is disclosed. The disclosed drophead nut maintains standard outward dimensions to allow interoperability with existing systems. The hitting surface of the drophead nut is typically used to align a gap in the nut with a retention pin and thus allow the nut to drop. This in turn allows a mid-plate to fall releasing pressure on a beam (joist and/or main) to allow that beam to be removed. The impact surface of the disclosed drophead nut has been enlarged, reinforced, and possibly repositioned to increase leverage. The resulting drophead nut may allow for reduction in number of impacts on an impact surface to provide alignment of the gap and retention pin, and thus activate compression of the drophead nut.
