Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and particularly relates to a jacking and assembling platform for a cable-stayed hanging basket. Background Art

[0002] With the development of highway bridge construction, the construction of cable-stayed bridges using cable-stayed hanging baskets has gradually become popular. The cable-stayed hanging basket is a technology for casting the main beam in suspension during the construction of modern cable-stayed bridges. At present, the most commonly used installation method for cable-stayed hanging baskets is as follows: the cable-stayed hanging basket is assembled integrally under the bridge, using the already cast beam segment as a stressed cantilever beam, and cooperating with lifting jacks and steel strands to lift the cable-stayed hanging basket integrally to the beam segment. Then, hooks are installed on both sides of the cable-stayed hanging basket and the cable-stayed hanging basket is hung on the tracks on both sides of the beam segment by means of a structure. After the cable-stayed hanging basket walks to the designed position, it is anchored.

[0003] The patent with the publication number CN220319075U discloses a cable-stayed hanging basket assembling platform, which fixedly connects distribution beams with a plurality of steel sheet piles at the construction site, and fixedly connects two adjacent steel sheet piles through a fixing mechanism to further enhance the stability of the steel sheet piles. Then, according to the construction drawings, the installation positions of the steel sheet piles are determined, the bearing platform is drilled, and the prefabricated steel bars on the steel sheet piles are inserted into the holes, so as to realize the fixed connection between the steel sheet piles and the bearing platform. The longitudinal beam is placed on a plurality of distribution beams located on the same horizontal line by a crane to realize the support of the longitudinal beam in the horizontal direction, and the longitudinal beam is initially positioned. Then, other components are hoisted to the installation positions by a crane and assembled with the longitudinal beam until the cable-stayed hanging basket is assembled. It is undeniable that the cable-stayed hanging basket assembling platform disclosed in this patent can indeed achieve the above technical effects, but it still has certain deficiencies: the cable-stayed hanging basket is large in volume, and a large assembling platform needs to be built during the overall assembly at the construction site. However, due to the influence and limitation of the construction site and the surrounding environment, it is impossible to build an assembling platform that meets the overall assembly of the cable-stayed hanging basket in a narrow construction site.
