FIELD: construction.
SUBSTANCE: in a rail system of a self-rising formwork used in construction, lifting rails are installed in lifting blocks, at the same time the lifting rails are integrated into a formwork unit. The formwork unit comprises also a working site and scaffolds of a lower row, which are also fixed on lifting rails. On free ends of lifting rails there may be elements installed to extent lifting rails and are fixed their with a rigid to bend connection.
EFFECT: elements to extend lifting rails have a smaller length compared to lifting rails.
