Description

Technical Field

[0001] The present invention relates to the technical field of building installation, and in particular to an assembled composite foundation with correction and adjustment functions. Background Art

[0002] Uneven foundation settlement is a long-standing technical problem in the field of construction engineering, which directly affects the structural safety and service life of buildings. In recent years, with the continuous advancement of civil engineering technology, many innovative patented technologies have emerged, which have significantly improved the accuracy and reliability of settlement adjustment. Hydraulic jacking technology occupies an important position in the field of building correction. Its essence is to precisely control the hydraulic jack system to lift the side of the building with the largest settlement, and gradually restore the verticality of the structure. This technology is particularly suitable for correcting existing buildings that have already tilted significantly. Typical application scenarios include urban dilapidated building renovation and historical building protection;

[0003] The jacking and correction technology has limitations that are difficult to avoid: during the construction process, the concrete of the frame structure columns and masonry structural columns needs to be chiseled out, and the steel bar connections need to be cut off during the jacking stage, which inevitably causes damage to the original structure of the building, especially for the structural integrity of high-rise buildings.

[0004] The traditional connection method between the upper cast-in-place structure and the foundation has significant disadvantages such as long construction period, poor quality stability, and insufficient seismic performance. It requires on-site formwork, steel bar tying, and concrete pouring and maintenance. It is not only restricted by weather conditions, but also prone to quality problems such as steel bar positioning deviation and concrete pouring defects. In addition, the rigid connection is prone to brittle failure during earthquakes.

[0005] Based on the above-mentioned problems of uneven settlement of the adjustment foundation and traditional connection methods, an assembled composite foundation with correction and adjustment functions is proposed. Summary of the Invention
