Shuttering for straight prefabricated concrete steps, with top and bottom landing

摘要

The top (14) and bottom (20) landings are joined to the step part (2) which has a metal frame (1) to which are joined shuttering elements (13,19) for the top and bottom landings by means of turning knuckles (12,21). The shuttering covers (10,16,23) for the metal frames are preferably made of sheet metal. An adjustable holder (15) is positioned between the step's frame and the top landing frame. The top part (17) of the steps' shuttering is rounded, and the adjacent part (18) of the top shuttering is hollowed out and grips over the rounded part.
