Chinese patent CN2016101958248 uses the beams added between the adjacent frame columns as the fulcrum, and the jack placed on the independent foundation can be used to increase the storey. The inventor believes that if the independent foundation has uneven settlement, it is very difficult to use this method to rectify the inclination. It is difficult to guarantee that the independent foundation will not continue to sink

Embodiment 1
[0043] like Figure 1-10 As shown, a frame structure jacking rectification method includes the following steps:
[0044] -like figure 2 , 3 , excavate a work pit 6 in the foundation soil 5 in the area where the foundation settlement of the leaning building is relatively large, exposing the independent foundation 2 under the frame column 1 there; Filling walls in between to provide space for rectification construction;
[0045] In this example, if figure 1 As shown, the foundation of the inclined building includes a plurality of frame columns 1 embedded in the independent foundation 2, and the arrangement between the frame columns 1 is arranged in a rectangular array; the foundation of the inclined building passes through the frame columns 1 Connect the independent foundation 2 and the bearing soil layer under the independent foundation 2; due to various reasons, such as environmental interference, changes in geological conditions, etc., the building is inclined, and this ...

The invention discloses an internal jacking incline-correcting method of a frame structure building. According to the internal jacking incline-correcting method of the frame structure building, the incline-correcting of the frame structure building can be carried out. The internal jacking incline-correcting method of the frame structure building comprises the following steps that a working pit isexcavated in the foundation soil in an area where the foundation settlement is relatively large of an inclined building, and independent footings under frame columns in the area are exposed; infilledwalls between frame columns and frame beams in same layers are dismantled; hole drilling is carried out; concrete grouting piles are arranged in drilled holes; an underpinning beam is arranged betweenadjacent frame columns, and the underpinning beam is fixedly connected with the frame columns; jacking devices are arranged between the concrete grouting piles and the underpinning beam, and at the same time, a balance weight is placed on the independent footing on the side with smallest settlement; the frame columns and the independent footings are lifted, and gaps between the lifted independentfootings and the working pit are filled with a concrete layer; and then the jacking devices are dismantled, and the underpinning beam is supported on the concrete grouting piles.
Description
technical field [0001] The invention belongs to the field of construction, and in particular relates to a method for jacking up and rectifying the interior of a frame structure building. Background technique [0002] Building rectification refers to the uneven settlement of the foundation caused by the foundation, the foundation or the building itself, and the upper structure of the building deviates from the vertical position and tilts. It refers to the rectification, rectification, reinforcement and stability measures taken during the safety and normal use of buildings in order to ensure the safety of buildings and restore their normal functions. [0003] The commonly used methods of rectification are: pile load pressurization rectification method, soil digging rectification method, water immersion rectification method and digging soil irrigation method, etc. Most of these methods are to increase the settlement on the side of the building where the settlement is small, so...
