Prefabricated concrete stairs formwork - has step forming components swivelled to adjust step height and width

摘要

The formwork is used for making of prefabricated stairs of concrete. It has step forming elements which can be rotated about vertical swivelling axis for adjusting step height. The stop forming elements (13) are swivelled so that there is formed a space between two adjacent step forming elements. Each of these spaces if filled by one or more inserts (38). The step forming elements are held on fixed swivelling axes and they can be swivelled by an adjusting rod together about their swivelling axes.
