Title:
CONSTRUCTION METHOD FOR QUICK-RELEASE CURVED SUPERIMPOSED BEAM FLANGE PLATE FRAMEWORK STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/155522
Kind Code:
A1
Abstract:
A construction method for a quick-release curved superimposed beam flange plate framework structure, comprising the following steps: transferring steel box girders (10) to designed positions; completing the assembly of framework structures each comprising adjustable bottom supports (2), ringlock brackets (1), adjustable top supports (4), and standardized formwork modules (11) which are sequentially provided from bottom to top; translating the framework structures to positions below a flange of a bridge deck to be poured (9) and on the outer sides of the steel box girders (10); sequentially adjusting arrangement orientations of the framework structures according to the shape of the curved superimposed beam, and embedding fan-shaped formwork modules (12) between every adjacent standardized formwork modules (11) and carrying out connection; using the adjustable top supports (4) to adjust the standardized formwork modules (11) and the fan-shaped formwork modules (12) to designed height positions; and completing the pouring of the bridge deck (9) under the support of the framework structures. The standardized formwork modules (11) are standard universal components and can be recycled. The fan-shaped formwork modules (12) can adjust the shape of a curve, and upper and lower steel plates (14, 15) hingedly connected to fan-shaped bamboo plywoods (7) of the fan-shaped formwork modules (12) can form grooves to facilitate connection.
