STAIRCASE FORM

摘要

A staircase form includes two or more stringers (12, 13), and, extending between the stringers, a plurality of risers (16). A network (20) of reinforcement rod, bar or plate for concrete is disposed below the risers. This network includes at least one elongate element (22) extending longitudinally of the form below the risers, and successive loops (26) linking the risers to the elongate element(s). The loops (26) are fixed to the rears of the risers (16), and also to the elongate element(s) (22) at respective locations coincident with or in proximity to the corresponding fixing locations of the next successive loops.
