The self-angle-changing hydraulic-climbing formwork system has the advantages that by adjusting the displacement adjusting devices, the inclination angle of the climbing guide rail can be changed so as to change the inclination angle of a form board system mounted on the climbing rack system to allow the form board system to adapt to the inner inclination, outer inclination and inner and outer inclination turning change of an outer frame cylinder, operation can be performed without the assistance of a tower crane, and high construction efficiency is achieved.

The invention discloses a construction method for a curved surface arc-shaped concrete tower. The curved surface arc-shaped concrete tower comprises double limb tower columns and tower top closure sections. Through a hydraulic climbing formwork method, the double limb tower columns are constructed section by section and step by step along the tower column elevation. During construction of the double limb tower columns, one or more temporary cross struts are installed between the double limb tower columns, brackets are embedded in the upper end inner side walls of all the tower columns to serve as fulcrums, bailey beams are hoisted on the brackets to serve as support platforms of the tower top closure sections, and finally, through a scaffolding method, concrete layered pouring construction is conducted to complete tower closure. The construction method can be used for an extra large cable-stayed bridge double curved surface arc-shaped concrete tower, a curved surface adjustable template is matched with a hydraulic climbing formwork system for construction, operation is convenient, safety is high, the curved surface adjustable template is convenient to adjust, the tower column linetype and matching precision are controlled from the source, and precision control over main tower hoisting is convenient.

The invention discloses an angle-adjustable hydraulic inclined climbing framework, which comprises operating frames, guide rails, rotating frames and jacking devices, wherein the operating frames andthe guide rails are fixedly connected with a wall body through wall attachment devices; the rotating frames are erected in the operating frames and connected with the operating frames and the guide rails respectively, the rotating frames are arranged in the middle parts of the guide rails, rotating shafts are arranged at places where the rotating frames and the operating frames are connected, andthus, the rotating frames can perform rotary movement relative to the operating frames around the rotating shafts; and the base of the jacking device is connected with the guide rail, and the jackingpart of the jacking device is connected with the rotating shaft. Attachment to a large-angle inclined wall / column structure for climbing can be realized, the angle of the inclined climbing framework can be adjusted according to structure angle changes, the adjustment accuracy is low, the operating difficulty is large, construction of a wall / column structure with large-angle inclination and angle changes can be effectively solved, the application range of the climbing formwork is expanded, and the construction problem of an inclined stiff mega column is solved.
