Abstract

The invention relates to a device for adjusting a web formwork of a box girder at a relaxation curve and a method for using the same. The device comprises a plurality of wedge-shaped formworks, and the tail height of each wedge-shaped formwork is the same as that of the head of the next wedge-shaped formwork. Among them, the wedge-shaped formwork at the thinner part is filled with wooden boards or rubber pads to form a solid wedge-shaped formwork, and the hollow wedge-shaped formwork at the thicker part is a channel structure welded by steel plates. The wedge-shaped formwork includes various specifications of modular design. The method of use can be poured in sections according to the wedge-shaped formwork of modular design. Thus, processing efficiency and construction efficiency are improved.

Description

technical field [0001] The invention relates to the field of highway mobile formwork construction, in particular to a device for adjusting a formwork for a box girder web at a relaxation curve and a method for using the formwork. Background technique [0002] The Pingtan Strait Road-Railway Bridge is the first cross-strait road-railway bridge in my country. The Strait Bridge is different from the Bay Bridge built in the past. Its construction faces harsh conditions such as strong winds, high waves, surges, strong typhoons, and complex geology. The construction of the bridge brought great challenges and high risks. This bridge is the first attempt in the field of cross-strait bridges in China. Whether it is the harshness of the environment, or the technical challenges and construction risks it faces, it is far superior to other cross-sea bridges that have been built or are under construction in China. The Pingtan Strait Highway-Railway Bridge is the first time in the world ...
