Abstract

The invention relates to the technical field of building construction, and discloses an installation and unloading method of a large-span cantilever corridor, a numerical simulation method is adopted to carry out modeling analysis on the corridor and a temporary supporting system, and the self-weight load effect of a corridor truss structure, the support reaction force before and after the temporary supporting system is unloaded and the stress between rods can be comprehensively considered. The deformation pre-adjustment value and the stress monitoring value of each construction stage are obtained, so that the implementation process of each construction stage of the construction site is guided. In addition, through early-stage numerical simulation analysis, the influence on the surrounding environment in the construction process is weakened, it is ensured that construction is safe and controllable, and the construction cost is saved. The temporary supporting system is unloaded in a multi-stage synchronous unloading mode, the problem of differential settlement generated in the cantilever corridor construction process can be effectively solved, and universality and generalization performance are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for installing and unloading a large-span cantilevered corridor. Background technique [0002] The corridor is the connecting structure between the buildings. On the one hand, the setting of the corridor is based on the requirements of the building function, and it can facilitate the connection between the two towers. At the same time, the conjoined body has good lighting effects and a wide field of view, so it can be used as a sightseeing corridor or a casual coffee shop. [0003] The design of the long-span cantilevered steel corridor is based on the designer's full consideration of the use function and fire protection requirements, combined with the building's flat and elevation shapes to create a visually impactful architectural product. However, the complex structure with peculiar shapes has brought great challenges to the engineering construction. Th...
