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.

Abstract: A wind turbine is formed of a concrete tower which is erected by slip forming. A primary lifting device is erected onto the tower by being lifted together with the slip form and being subsequently transferred onto the tower from the slip form after the tower has been formed. The nacelle, generator, and rotor of the turbine are then lifted onto the tower using the primary lifting device. A secondary lifting device supported on the tower is used to lower the primary lifting device to the ground after the nacelle, generator and rotor are assembled. The height of the tower is therefore not limited by the availability of suitable cranes so that a greater height of tower can be erected to take advantage of winds at greater elevation.

Abstract: A vertically adjustable overhang bracket uses an elongate base component adapted to be supported from a support column. A frame member is slidably secured to the base component to allow movement of the frame along the length of the elongate base component. The frame is of a shape to provide an outwardly extending support member for supporting concrete formwork members to one side of the base component. An actuator controls the position of the frame, relative to the elongate base component. With this arrangement, concrete formwork can be more easily supported in a cantilevered manner from support columns and vertically adjusted quickly to the proper position. Removal of the formwork is simplified as the frame can be lowered, relative to the base component providing clearance for removal of the bracket and the formwork.
