Building one-way deviation rectification method

Abstract

The invention relates to the field of building deviation rectification, and particularly discloses a building one-way deviation rectification method. Deviation rectification of a building with settlement in a single direction can be realized, and a concrete column and steel bars in the column on one side needing deviation rectification in the building only needs to be disconnected in the deviation rectification process. Whether the concrete column on the side, not needing to be corrected, of the building and the steel bars in the column need to be disconnected or not is judged according to the following formula that when gamma delta h is smaller than 0.09 H, the concrete column on the side, not needing to be corrected, of the building and the steel bars in the column do not need to be disconnected; and when gamma delta h is larger than 0.09 H, the concrete column on the side, not needing deviation rectification, in the building needs to be disconnected, and the steel bars in the column close to the side needing deviation rectification in the concrete column further need to be disconnected. Therefore, by means of the one-way deviation rectification method for the building, the number of the concrete jacking bearing platforms can be reduced, damage to the original structure of the building is reduced, and the building one-way deviation rectification method has the advantages of being low in manufacturing cost, simple in procedure and short in construction period.

Description

technical field [0001] The invention relates to a building deviation correction method, in particular to a building one-way deviation correction method. Background technique [0002] For buildings with a frame structure that is inclined in one direction due to uneven settlement of the foundation, the deflection correction technology of broken columns can be used to correct the deflection. , and set up a jacking device between the upper and lower concrete jacking caps of all concrete columns on the side of the building that needs to be jacked up, the jacking device can pass through a jack and a corresponding supporting structure (such as a steel pad) and set hinged caps between the upper and lower concrete jacking caps in all the concrete columns on the side that does not need to be lifted; then disconnect all the concrete columns and the steel bars in the concrete columns, and pass through the jacking device The jack lifts the inclined side of the building, so that the whol...
