Abstract

The invention relates to a formwork with an improved structure for the production of monolithic steps for spiral staircases and to a corresponding method for the manufacture of said staircases. This formwork comprises a substantially semi-cylindrical base element which has, arranged on it, in a more or less vertical position, three shaped walls designed to define, in terms of form, the tread board, the raised front-piece and two side strips provided, on external faces, with suitable helical grooves. The abovementioned three walls, at least two of which may be fastened to the aforesaid base element by means of bolts or functionally equivalent elements, may be connected together by means of fast-locking tie-rods or the like. <IMAGE>
