Abstract:
1. A method for constructing multi-story concrete structures using a rail-guided self-climbing formwork system, the concrete structures having a lower concrete section forming a vertical wall of a ground-floor story and at least one upper concrete structure extending vertically from an upper end of the first concrete structure, the method comprising the steps of: a) attaching a first lower climbing shoe and a first upper climbing shoe to the lower concrete section; b) disposing a climbing rail in a displaceable manner within the first lower and the first upper climbing shoes, the climbing rail having a length which is substantially equal to a height of the lower concrete section; c) displacing the climbing rail in a vertical direction within the first lower and first upper climbing shoes; d) positioning a lower extension piece to extend vertically in a downward direction below a lower end of the climbing rail and securing the lower extension piece to the climbing rail in that position, said lower extension piece having a length which is less than the length of the climbing rail; and e) further displacing the climbing rail in the vertical direction until the lower extension piece is captured within the first lower climbing shoe.
