Embodiment 1
[0052] Taking a three-story, three-span frame structure building with independent foundations as an example, figure 1 with figure 2 It is a schematic diagram of the original frame structure building, the building is supported by the foundation 1 at the lower part of the outdoor ground 5, and the upper part of the foundation 1 supports the frame columns 2, and the frame columns 2 are connected by three-layer frame beams and slabs 3, and the frame columns 2 are inside The upper part of the foundation 1 has an indoor ground 4 .
[0053] Such as Figure 3-Figure 12 As shown, taking a three-story, three-span frame structure building with an independent foundation as an example, the specific process of building jacking, adding floors and seismic isolation methods is as follows:
[0054] (1) Excavate the earthwork above the foundation 1 below the outdoor ground 5 at the bottom of the building to expose the foundation 1.
[0055] (2) Between each frame column 2, a newly added bottom...
