as lost shuttering a substantial bewehrungselement for a steel concrete verbundbauteil

摘要

The element (1) produced by the lost form method has a cross sectional shape which approximates to the shape of the support line. The profile is formed as a polygon. The profile, at least in the lower regions, is made to follow the support line, and has level surface areas (7). Naps or burls (8) are distributed over the surface of the element which faces the concrete structure (9).
