Title: CLIMBING FORMWORK AND METHOD FOR ERECTION OF A CONCRETE STRUCTURE
Abstract:
A climbing formwork (1) and a method for erection of a concrete structure by successively casting a plurality of casting segments (16), the climbing formwork comprising - at least a first form element (4) for delimiting a cavity (6) to receive concrete for forming an uppermost casting segment, the first form element (4) having an upper end and a lower end, - a first support structure (7) to support the first form element (4), - a first tilt sensor (15) for measuring a tilt of the first form element (4), - a first measuring unit (17) for measuring a horizontal distance between the lower end of the outer surface (4a) of the first form element (4) and the upper end of the outer surface (16a) of the previous casting segment (16), - a processing unit (18) communicating with the first tilt sensor (15) and the first measuring unit (17), the processing unit (18) being arranged for calculating a target tilt of the first form element (4) using the measurement of the horizontal distance between the lower end of the outer surface (4a) of the first form element (4) and the upper end of the outer surface (16a) of the previous casting segment (16), the processing unit (18) further being arranged for determining a deviation between the actual tilt and the target tilt of the first form element (4).
