Abstract
A method is proposed for constructing multi-story concrete structures using a rail-guided self-climbing formwork system. A climbing rail is thereby displaced in a vertical direction within lower and upper climbing shoes and a lower extension piece is positioned to extend vertically in a downward direction below a lower end of the climbing rail. The lower extension piece has a length which is less than the length of the climbing rail. The climbing rail is then displaced in the vertical direction until the lower extension piece is captured within the lower climbing shoe. The method simplifies construction of the lower stories of concrete structures.
