Description

Technical Field

[0001] This invention relates to the field of building installation technology, and in particular to a prefabricated composite foundation with correction and adjustment functions. Background Technology

[0002] Uneven foundation settlement, a long-standing technical challenge in the construction engineering field, directly affects the structural safety and service life of buildings. In recent years, with the continuous advancement of civil engineering technology, numerous innovative patented technologies have emerged, significantly improving the accuracy and reliability of settlement adjustment. Hydraulic jacking technology plays a crucial role in building correction. Its essence lies in using a precisely controlled hydraulic jack system to selectively lift the side of the building with greater settlement, gradually restoring the structural verticality. This technology is particularly suitable for correcting existing buildings that have already experienced significant tilting; typical applications include urban dilapidated building renovation and historical building preservation. The jacking and correction technology has unavoidable limitations: during construction, it is necessary to remove the concrete of the frame structure columns and masonry structural columns, and cut the steel reinforcement connections during the jacking stage. This inevitably damages the original structure of the building, especially the structural integrity of high-rise buildings.

[0003] Traditional methods of connecting cast-in-place structures to foundations have significant drawbacks, such as long construction periods, poor quality stability, and insufficient seismic performance. They require on-site formwork, rebar tying, and concrete pouring and curing, which are not only subject to weather conditions but also prone to quality problems such as rebar positioning deviations and concrete pouring defects. Furthermore, rigid connections are susceptible to brittle failure during earthquakes.

[0004] Based on the above-mentioned issues of uneven settlement of the foundation and the problems of traditional connection methods, a prefabricated composite foundation with correction and adjustment functions is proposed. Summary of the Invention

[0005] To address the technical problems existing in the prior art, the present invention provides a prefabricated composite foundation with correction and adjustment functions.

The adjustment mechanism includes a main body, a screw rod 1 that is threadedly connected to the top of the main body and is threadedly connected to the connecting mechanism, a screw rod 2 that is threadedly connected to the bottom of the main body and is threadedly connected to the locking mechanism, a support rod that is fixed to one side of the main body, a deflection rod that is rotatably connected to the other end of the support rod, a movable tube that is slidably connected to the bottom of the deflection rod, and a docking groove with an arc-shaped structure for docking with the locking mechanism is opened at the bottom of the movable tube. The locking mechanism includes a base plate connected to the soil-embracing composite pile, a sleeve 1 that is threadedly connected to the top of the base plate and the outer side of the sleeve 1 is provided with a limiting tube that is fixedly connected to the top of the base plate and the limiting tube is connected to the movable tube.

[0007] As a further improvement to the above solution, the connecting mechanism includes a top plate for docking with the building, a sleeve two for threaded connection with a screw rod is fixed to the bottom of the top plate, and an installation hole one for installation is provided in the top plate for connection with the building.

[0008] As a further improvement to the above scheme, the outer ring of the sleeve one is fixedly connected to the diagonal brace which is fixedly connected to the base plate, and the base plate has a second mounting hole through it, and the second mounting hole is provided with a second mounting screw for connecting to the soil-embracing composite pile.

[0009] As a further improvement to the above solution, the inner ring of the limiting tube is provided with locking teeth arranged sequentially along its axial direction, and the inner side wall of the docking groove is provided with a locking groove arranged along its length direction, and the locking groove engages with the locking teeth.

[0010] As a further improvement to the above scheme, the soil-embracing composite pile includes a pile cap for connection with a locking mechanism, the pile cap having a through hole for connection, and multiple sets of arrayed piles fixed to the bottom of the pile cap, with a tip for insertion at the bottom of the pile.

[0011] As a further improvement to the above solution, both sleeve 2 and sleeve 1 have internal threads on their inner rings, and the main body drives sleeve 2 and sleeve 1 to move in opposite directions when rotating along its axis.

[0012] As a further improvement to the above solution, both sleeve 2 and sleeve 1 have annular guide grooves at their ends that are far apart from each other, and the cross-section of the guide grooves is triangular.

[0013] As a further improvement to the above solution, a locking screw is threaded onto one side of the top of the movable tube, and a handle is installed at the end of the locking screw that extends out of the movable tube. A positioning hole is reserved on the outside of the deflection rod for the locking screw to extend into.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a modular design to reduce damage and modification operations during the correction process of existing buildings, improve the efficiency of building installation operations, and protect the integrity of the structure.

[0015] This invention enables the adjustment of building installation, adjusting the building's position to adapt to uneven settlement under different foundation conditions. It overcomes the problem of cumbersome and inconvenient adjustment operations under uneven settlement conditions in traditional building systems, and improves the adaptability of building installation.

[0016] This invention uses a method in which the pile and the soil share the load, thereby improving the overall bearing capacity. Attached Figure Description

The bottom of the locking mechanism 3 is connected to a soil-holding composite pile 4. The soil-holding composite pile 4 is inserted into the position where the building needs to be installed beforehand. Then, the locking mechanism 3 is installed on the top of the soil-holding composite pile 4, and the connecting mechanism 1 is installed at the bottom of the building to be installed. The prefabricated building body is hoisted to the top of the soil-holding composite pile 4 using hoisting equipment.

A screw 23, which is threadedly connected to the locking mechanism 3, is fixed to the bottom of the main body 21. A support rod 24 is fixed to one side of the main body 21. A deflection rod 25 is rotatably connected to the other end of the support rod 24. A movable tube 26 is slidably connected to the bottom of the deflection rod 25. The bottom of the movable tube 26 has a docking groove 27 with an arc-shaped structure for docking with the locking mechanism 3. A locking screw is threadedly connected to one side of the top of the movable tube 26. A handle is installed at the end of the locking screw that extends out of the movable tube 26. A positioning hole is reserved on the outside of the deflection rod 25 for the locking screw to extend into. Screw 22 is inserted into sleeve 12 of connecting mechanism 1, and screw 23 is inserted into sleeve 32 of locking mechanism 3. Deflecting rod 25 is deflected to one side and pushed to make support rod 24 drive main body 21 to rotate along its axis. At this time, under the action of screw 22 and screw 23, sleeve 12 and sleeve 32 move in opposite directions, adjusting the distance between connecting mechanism 1 and locking mechanism 3, thereby adjusting the distance between building body and soil-embraced composite pile 4, thus realizing the position adjustment operation of building body; The locking mechanism 3 includes a base plate 31 connected to the soil-embracing composite pile 4. A sleeve 32, threadedly connected to a screw rod 23, is fixedly connected to the top of the base plate 31. A limiting tube 35, fixedly connected to the top of the base plate 31, is provided on the outer side of the sleeve 32, and is connected to the movable tube 26. An inclined brace 33, fixedly connected to the base plate 31, is fixedly connected to the outer ring of the sleeve 32. A second mounting hole 34 is provided through the base plate 31, and a second mounting screw rod for connecting to the soil-embracing composite pile 4 is provided in the mounting hole 34. The inner ring of the limiting tube 35... The mating groove 27 is provided with locking teeth arranged sequentially along its axis, and the inner side wall of the mating groove 27 is provided with a locking groove arranged along its length, and the locking groove engages with the locking teeth; after the adjustment mechanism 2 completes the position adjustment of the connecting mechanism 1 and the locking mechanism 3, the deflection rod 25 is deflected downward so that the deflection rod 25 is directly above the limiting tube 35, and then the movable tube 26 is pushed downward so that the mating groove 27 and the limiting tube 35 are engaged by locking the teeth and locking the groove, thereby realizing the fixed restriction operation of the adjustment mechanism 2.

[0022] Example 2

[0023] This embodiment is further improved on the basis of embodiment 1 in that: the connecting mechanism 1 includes a top plate 11 for docking with the building structure, a sleeve 12 for threaded connection with screw 22 is fixedly connected to the bottom of the top plate 11, the top plate 11 has a mounting hole 13 for installation, and the mounting hole 13 is provided with a mounting bolt 14 for connection with the building structure; the inner rings of sleeve 12 and sleeve 32 are both provided with internal threads, and the main body 21 drives sleeve 12 and sleeve 32 to move in opposite directions when rotating along its axis; the ends of sleeve 12 and sleeve 32 that are far apart from each other are provided with annular guide grooves, and the cross-section of the guide grooves is triangular. The soil-embracing composite pile 4 includes a pile cap 41 for connection with the locking mechanism 3. The pile cap 41 has a through hole 42 for connection. Multiple sets of arrayed pile bodies 43 are fixed to the bottom of the pile cap 41. The bottom of the pile body 43 is provided with a pointed tip 44 for insertion. The pile body 43 is inserted into the ground of the building to be installed and extends into the soil. At this time, the pile cap 41 and the pile body 43 form a temporary building installation support structure to support the building. At this time, the soil between the pile body 43 and the adjacent pile body 43 jointly bears the load, improving the overall bearing capacity. The four pile bodies 43 in the soil-embracing composite pile 4 hug the soil from the four feet to form a "pile + soil" composite pile system. The composite system then forms friction with the soil, which constitutes the working mechanism of the composite pile.

[0024] This invention employs a modular design to reduce damage and modification to existing buildings during the correction process, improve the efficiency of building installation, and protect the integrity of the structure. It enables adjustment operations during building installation, allowing the building to adapt to uneven settlement under different foundation conditions, thus overcoming the cumbersome and inconvenient adjustment operations of traditional buildings under uneven settlement conditions and increasing the adaptability of the building installation. Furthermore, it utilizes a method where piles and soil share the load, enhancing the overall bearing capacity.
