Shuttering for concrete stairs with step shutting elements - has each shuttering element swivelable about axis vertical to shuttering bottom

摘要

There is a shuttering wall for the head surface and the butting face of a step, whose shuttering elements (13) are mutually adjustable. They are fixable in selected positions above the shuttering bottom (19) in a row next to each other. Each step shuttering element is swivelably mounted in a holder (6), swivelling about a vertical axis (14) w.r.t. the shuttering bottom. The swivel axis lies in the longitudinal edge of the shuttering wall for the tread. The angular position of the shuttering elements and the spacing of adjacent swivel axes are adjustable for setting the tread width. ADVANTAGE - Easy adjustment to any stair dimensions.
