Lost shuttering element for prefabricated concrete floor beams or slab edges has vertical edge and thrust members with connecting pieces between

摘要

The shuttering element consists of a vertical edge member (1), a parallel vertical thrust member (2) of the same length as the edge member but lower, and perpendicular connecting pieces between them, aligned with the upper edge of the thrust member. Corner elements can be made with two-section edge and thrust members at right angles, joined by two connecting pieces each, and both edge and thrust members have rebated ends (4) to connect them with adjoining elements.
