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.

Abstract: A method and a climbing device for lowering a climbing rail, i.e. for climbing downwards. The climbing rail, which is placed on a climbing head by means of an upper protrusion, is lowered in that a climbing cylinder is retracted. The climbing cylinder can be spaced from the climbing rail by completely retracting the climbing cylinder at the upper end by means of a distancing device prior to extending the climbing cylinder again. Thus, the climbing cylinder can be extended again without the climbing rail engaging or hooking below the climbing head at the now central protrusion in that the distancing device moves the climbing head around the central protrusion.
