Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge cantilever construction hanging basket. Background Art

[0002] Cast-in-place cantilever beams are often cast in-place using conventional hanging baskets. Conventional hanging baskets mainly include two main trusses and a side formwork and bottom formwork system. The two main trusses are respectively arranged on both sides of the top surface of the bridge along the direction of the bridge. The rear end of the longitudinal beam is anchored to the already cast beam section, and the front end of the longitudinal beam forms a cantilever in front of the beam section to be cast. The front and rear crossbeams of the bottom formwork are located below the already cast beam section and the beam section to be cast. The front and rear lower crossbeams are connected to the main trusses through four-corner slings, providing support for the bottom formwork when the hanging basket moves forward to cast the next section. However, when constructing two bridges with a small lateral space clearance, the four-corner slings on the outside of the beam body will interfere with each other. For the construction of cable-stayed bridges with cables on both sides of the beam body, the slings may also collide with the cables, causing inconvenience in construction. Therefore, it is necessary to improve the support method when the hanging basket is moving. Utility Model Content
