Embodiment Construction

[0083] figure 1 A climbing formwork 1 for progressive erection of a concrete structure 2, such as a skyscraper, is shown. The concrete structure 2 is erected by a plurality of casting steps in which a corresponding number of casting sections 3 are formed, each of which corresponds to a floor of the concrete structure 2 . To this end, the climbing formwork 1 comprises a first formwork element 4 and a second formwork element 5 . Each of the first formwork element 4 and the second formwork element 5 comprises a formwork panel. In the casting position, the first formwork element 4 and the second formwork element 5 define a cavity or space 6 therebetween for receiving concrete for forming the uppermost casting section. In detail, the outer surface 4a of the first formwork element 4 faces the cavity 6, while the inner surface 4b of the first formwork element 4 faces away from the cavity 6 to receive the concrete. Usually, the reinforcement 10 is arranged in the cavity 6 between ...

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 ofthe 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 arrangedfor determining a deviation between the actual tilt and the target tilt of the first form element (4).

Description

technical field [0001] The invention relates to a climbing formwork for erecting concrete structures by successively pouring several casting sections. Background technique [0002] In the prior art, climbing formwork is used to erect concrete structures, such as skyscrapers, in several successive casting steps. This climbing formwork can be repositioned between pouring steps, or it can move upwards by itself. The latter type of climbing formwork is often referred to as jack-up formwork. Some examples are shown in US 2010 / 0038518 A1 or WO 2013 / 110126 A1. Another type of climbing formwork is disclosed in WO 2011 / 127970. [0003] EP 1 806 559 discloses a measurement procedure for high-rise buildings which are subject to tilting effects and prevent the use of ground level reference points. The system uses at least three receivers of a satellite-based positioning system to determine the positions of three reference points equipped with reflectors on the highest floors of buil...
