Document Type and Number:
WIPO Patent Application WO/2022/033031
Kind Code:
A1
Abstract:
Provided is a method for inclination rectification of a building of a brick-concrete structure by means of spatial curved surface rotational displacement, which relates to the field of inclination rectification for buildings. In the method, an annular working pit is excavated around a building, with a side slope of the working pit being of a spatial curved surface structure corresponding to an inner surface of a spherical portion, and a strip foundation of a brick-concrete building being completely exposed and all within the range of the working pit; and a rotational displacement track is laid on the side slope of the working pit corresponding to the spatial curved surface structure thereof. For overall inclination which may be generated in any direction of a building, inclination rectification is realized by means of rotational displacement using a three-dimensional spatial curved surface track, so as to overcome the limitation at present of inconsistency between an inclination direction and a main axis arrangement direction during inclination rectification by two-dimensional path inclination rectification; and after the inclination rectification, a self-recovery structure is formed that can achieve seismic isolation of a seismic acting force in any direction.
