Shuttering which comprises profiled sheet metal and is intended for concrete composite floors

摘要

A shuttering which comprises profiled sheet metal and is intended for concrete composite floors exhibits downwardly open, mutually parallel ribs (3) of trapezoidal cross-section and upwardly directed folds (4) which are arranged between the ribs (3), run parallel thereto and are bent out of the sheet metal. The folds (4) are provided with a wave form in the longitudinal direction. The amplitudes of the generatrices of the waves are highest at the free, top fold edge (5) and fall until they reach zero value at the bottom edge (6). <IMAGE>
