High-layer shear wall structure jacking deviation rectifying device and operation method

Abstract

The invention discloses a high-layer shear wall structure jacking deviation rectifying device. The high-layer shear wall structure jacking deviation rectifying device comprises an upper underpinning bearing platform connected with the bottom end of a jacked upper shear wall structure and a lower underpinning bearing platform connected with an original lower structure; a plurality of jacks are evenly and symmetrically arranged at the bottom of the upper underpinning bearing platform, and the bottoms and the tops of the jacks are provided with local pressing preventing steel cushion blocks; anda plurality of limiting supporting piers are symmetrically arranged on the lower underpinning bearing platform and the original lower structure, the bottoms of the limiting supporting piers are connected with bottom plates of the lower structure, and pressure bearing steel beams and adjustable cushion plates are arranged between the tops of the limiting supporting piers and the upper underpinningbearing platform. According to the high-layer shear wall structure jacking deviation rectifying device, upward and stable jacking can be conducted evenly and constrainedly, on the one hand, the limiting supporting piers can share the jacking force of the jacks, stress concentration of the upper underpinning bearing platform and influences on the upper structure can be reduced, and on the other hand, the limiting supporting piers can effectively avoid horizontal deviation generated due to uneven jacking force in the jacking process, and the safety and the reliability of the jacking deviation rectifying process are guaranteed.

Description

technical field [0001] The utility model relates to the technical field of construction engineering, in particular to an overall jacking and rectifying device for a high-rise shear wall structure and an operation method. Background technique [0002] With the continuous advancement of the urbanization process, there are more and more large-scale high-rise buildings. Due to the large load of high-rise buildings, coupled with factors such as survey, design and construction, the situation of building tilt occurs from time to time. For buildings The existing building deviation correction methods mainly include forced landing method and jacking method. [0003] Among them, the jacking method is to set up a jacking platform on the vertical load-bearing member. After the structure is cut off and separated at a certain position, the whole structure is lifted by a jack. The operation process usually begins to lift an order of magnitude along one direction. After a certain height, th...

Problems solved by technology

Due to the separation of the lifted superstructure from the original substructure during the jacking process and the vertical constraints, it is difficult to ensure the uniformity of the jacking force and the synchronization and coordination of the jacking displacement, so it is easy to cause horizontal misalignment between the superstructure and the original substructure.
