Method and device for the construction of reinforced-concrete or prestressed-concrete bridge superstructures in sections

摘要

The invention relates to a method, and also to a device suitable for carrying out the method, for the construction of superstructures, mounted on a pier (2), in sections, the individual constructional sections being built out on both sides of the pier table (4) one after another. The object to be solved is that of reducing the total construction time, while keeping the weight and volume of the laying apparatus and the formwork low. According to the invention, using a laying apparatus (6) which is supported on the previously fabricated constructional sections (r, r-1), a prefabricated base slab (32) of the next constructional section (r+1) is laid and anchored to the base slab (31) of the previously concreted constructional section (r). The base slab (32) is secured against tilting by means of the laying apparatus (6) and/or bracing (34, 40, 42). Laying apparatus (6), whose integrated formwork (30) does not contain any base formwork, can be moved to the next-but-one constructional section (r+2) even before prestressing of the next constructional section (r+1).
