Abstract

The invention discloses a building deviation rectification asynchronous jacking method and belongs to the technical field of building (construction) jacking and deviation rectification. The building deviation rectification asynchronous jacking method comprises the following construction technology processes: A, carrying out the construction technology process before jacking; B, carrying out the construction technology process of asynchronous jacking; C, carrying out the construction technology process of levelling; D, carrying out the construction technology process of synchronous jacking; andE, carrying out the construction technology process after jacking. Asynchronous jacking adopts column-by-column (point location) cutting and column-by-column jacking manner and utilizes the componentof the original structure to resist the horizontal force generated due to inclination to the maximum; the deflection of a beam body is fully utilized to reduce the building slope gradient after column breaking in disguised form; during the deviation rectification process, normal production and operation of the building can be ensured to a greater degree; and compared with the traditional jackingdeviation rectification method, the controllability, precision and safety of asynchronous jacking construction are higher.

Description

technical field [0001] The invention relates to an asynchronous jacking method for building deviation correction, which belongs to the technical field of building (structure) jacking and deviation correction. Background technique [0002] Building jacking correction technology has become more and more mature after development in recent years. Jacking deviation correction has the advantages of strong controllability, high precision and fast deviation correction speed. At present, the synchronous jacking method of buildings mainly includes three steps: 1. The construction process flow before jacking; 2. The construction process flow of synchronous jacking; 3. The construction process flow after jacking. The traditional jacking correction mainly adopts synchronous and proportional jacking of broken columns, but for buildings whose inclination is seriously beyond the limit, if the traditional jacking and correcting method of synchronous and same proportion is continued, large-a...
