Abstract (en)

Method and apparatus for constructing long span reinforced shell-shaped, substantially horizontal concrete structures. The concrete structures art constructed in a continuous casting process by utilizing a inclined casting surface (26) and by applying a completely or partly displaceable or movable formwork (27). The formwork (27) comprises a number of joining formwork modules (18) which repeatedly are moved from the front end (31) of the formwork to the rear end (33) of the formwork. Reinforcement are mounted and prestressing cables are tightened, and these operations are carried out independently of the casting process. During the continuous casting process, the complete structure is sequentially moved in a forward direction with and without the formwork until the concrete structure has achieved a desired length. <IMAGE>
