Problems solved by technology

The use of elevation compensation can only solve the problem of vertical elevation differences, but it cannot solve the additional internal force of horizontal structures caused by differential deformation
In addition, the existing elevation compensation is determined based on finite element or numerical calculations. In actual engineering, the material properties, boundary conditions, and load conditions are slightly different from those of the calculation model, resulting in slight differences between the calculation results and the actual differential deformation.
The rear closure of outrigger trusses and other horizontal structures can effectively avoid the additional internal force of the horizontal structure, but due to the influence of the unclosed horizontal structure on the subsequent construction, it is not conducive to the full development of the construction and affects the construction period

Abstract

The invention provides a differential deformation compensation device, a differential deformation compensation system and a using method thereof. The differential deformation compensation device, the differential deformation compensation system and the using method thereof aim to effectively reduce horizontal structure internal force accumulation generated by vertical deformation difference of a core tube and a frame column and avoid the influence of post-closing measures of an outrigger truss and other horizontal structures on the whole construction progress.

Description

technical field [0001] The invention belongs to the technical field of super high-rise building construction, and in particular relates to a differential deformation compensation device, a differential deformation compensation system and a use method thereof. Background technique [0002] Due to the different cross-sections of core tubes and frame columns in super high-rise buildings, they are subjected to different internal forces, and there are usually large vertical differential deformations due to different material properties. The difference in vertical deformation not only causes the level deviation of the horizontal structure, but also causes the additional internal force of the horizontal structure, and even the damage of the joints. Therefore, it is necessary to focus on the differential deformation of the core tube and the frame column. [0003] Super high-rise deformation mainly includes the following aspects, first, the vertical deformation of the structure under...
