Description

Technical Field

[0001] This invention relates to the field of building installation technology, and in particular to prefabricated sliding vibration-damping composite foundations. 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.

[0003] 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.

[0004] 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.

[0005] 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

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1:

[0035] Please combine Figures 1-8 The prefabricated sliding shock-absorbing composite foundation of this embodiment includes a shock-absorbing component 2 set at the bottom of the main building, a foundation platform 1 set at the bottom of the shock-absorbing component 2, and a pile-holding composite component 3 for supporting the building connected to the foundation platform 1.

[0036] The damping assembly 2 includes a damping mechanism 4 for connection with the main building, an adjustment mechanism 5 fixed to the bottom of the damping mechanism 4, and a support locking mechanism 6 threadedly connected to the bottom of the adjustment mechanism 5 and the foundation pedestal 1.

[0037] The pile-holding composite component 3 includes a connecting mechanism 7 connected to the foundation cap 1, an adjustment mechanism 2 8 fixed to the bottom of the connecting mechanism 7, a support locking mechanism 2 9 threaded to the bottom of the adjustment mechanism 2 8, and a soil-holding composite pile 10 fixed to the bottom of the support locking mechanism 2 9.

[0038] The soil-embracing composite pile 10 includes a pile cap 101 for connection with a second support locking mechanism 9. The pile cap 101 has a through hole 102 for connection. Multiple sets of arrayed piles 103 are fixed to the bottom of the pile cap 101. The bottom of each pile 103 is provided with a tip 104 for insertion. The piles 103 are inserted into the ground of the building to be installed and extend into the soil. At this time, the pile cap 101 and the piles 103 form a temporary building installation support structure to support the building. At this time, the soil between the piles 103 and the adjacent piles 103 jointly bears the load, improving the overall bearing capacity. The four piles 103 in the soil-embracing composite pile 10 hug the soil from four feet, forming a "pile + soil" composite pile system. The composite system then forms friction with the soil, which constitutes the working mechanism of the composite pile.

[0039] It also includes building support components installed on the main body of the building. The building support components are the main basic components of the building, such as shear walls, columns, and foundation ring beams. The building support components are inlaid with connecting sleeves that are threaded into the shock absorption mechanism 4. The bottom of the connecting sleeve is provided with a shock-absorbing rubber pad for contacting the building mechanism 4.

[0040] The pile-holding composite component 3 is pre-installed at the building placement location. Then, the foundation platform 1 is connected to the pile-holding composite component 3. After that, the damping component 2 is installed on the foundation platform 1. Then, the building body with the building support components is hoisted to the top of the building component 2 and connected to the damping component 2 using the hoisting equipment. Then, the positions of the damping component 2 and the pile-holding composite component 3 are adjusted using the adjustment mechanism 1 5 and the adjustment mechanism 2 8. The adjustment position is determined according to the level 13 on the foundation platform 1 to ensure that the building is placed stably.

[0041] Example 2:

[0042] Based on Embodiment 1, this embodiment further improves upon the following: the damping mechanism 4 includes a support column 41, with a connecting screw 45 fixedly connected to the top of the support column 41 for connecting to the main building body, and a spherical groove opened at the bottom of the support column 41. A deflection ball 42 is slidably connected to the groove, and an extension rod 43 is fixedly connected to one end of the deflection ball 42 extending out of the groove. A buffer spring 44 is fixedly connected to the bottom of the extension rod 43 and to the top of the support rod 82 of the adjustment mechanism 5. When the deflection ball 42 slides in the groove and the buffer spring 44 buffers, the building is adjusted by sliding. At the same time, when the adjustment mechanism 5 adjusts the position, the buffer spring 44 is adjusted by sliding the deflection ball 42.

[0043] Adjustment mechanism 2 8 includes a main body 81 fixedly connected to the bottom of the connecting mechanism 7. The bottom of the main body 81 is fixedly connected to a screw rod 86 threadedly connected to the support locking mechanism 2 9. A support rod 82 is fixedly connected to one side of the main body 81. The other end of the support rod 82 is rotatably connected to a deflection rod 83. A movable tube 84 is slidably sleeved at the bottom of the deflection rod 83. The bottom of the movable tube 84 has a docking groove 85 with an arc-shaped structure for docking with the support locking mechanism 2 9. The adjustment mechanism 2 8 has the same structure as adjustment mechanism 1 5. Deflecting the deflection rod 83 to one side and pushing the deflection rod 83 causes the support rod 82 to drive the main body 81 to rotate along its axis, which can drive the screw rod 86 and the screw rod 75 to rotate. Under the action of the screw rod 86 and the screw rod 75, the sleeve 72 and the sleeve 32 move in opposite directions, adjusting the distance between the connecting mechanism 7 and the support locking mechanism 2 9, thereby adjusting the distance between the building and the soil-embraced composite pile 10, thus realizing the position adjustment operation of the building.

[0044] The second support locking mechanism 9 includes a base plate 91 connected to the support platform 101. A sleeve 92 that is threadedly connected to the top of the base plate 91 is fixedly connected to the top of the adjustment mechanism 8. A limiting tube 94 that is fixedly connected to the top of the base plate 91 is provided on the outside of the sleeve 92. The limiting tube 94 is connected to the adjustment mechanism 8. The second support locking mechanism 9 has the same structure as the first support locking mechanism 6.

[0045] After the adjustment mechanism 28 completes the position adjustment of the connecting mechanism 7 and the support locking mechanism 29, the deflection rod 83 is deflected downward so that the deflection rod 83 is directly above the limit tube 94. Then the movable tube 84 is pushed downward so that the docking groove 85 and the limit tube 94 are engaged by a slot and tooth method, thereby realizing the fixed restriction operation of the adjustment mechanism 28.

[0046] The connecting mechanism 7 includes a top plate 71 for docking with the foundation 1. A sleeve 72 is fixedly connected to the bottom of the top plate 71. A screw 75, which is fixedly connected to the support rod 82 of the adjusting mechanism 8, is threaded onto the sleeve 72. The top plate 71 has a mounting hole 73 for installation. The mounting hole 73 is provided with a mounting bolt 74 for connecting with the building structure.

[0047] The base platform 1 includes a base plate 11. The four sides of the top of the base plate 11 are provided with inwardly recessed storage grooves 12. A level gauge 13 is installed inside the storage groove 12 along the length of the adjacent side of the base plate 11. The base plate 11 has a waist hole 14 for connection and installation. The horizontal position of the base plate 11 after adjustment is determined according to the position of the level gauge 13 located on the four sides of the base plate 11.

[0048] The outer side of the sleeve 92 is fixed with a diagonal brace 93 that is fixed to the base plate 91. The base plate 91 has a second mounting hole. The second mounting hole is provided with a second mounting screw for connecting to the support 101. The limit tube 94 and the second adjustment mechanism 8 are engaged by a toothed groove.

[0049] A locking screw is threaded onto one side of the top of the movable tube 84. A handle is installed at the end of the locking screw that extends out of the movable tube 84. A positioning hole is reserved on the outside of the deflection rod 83 for the locking screw to extend into.

[0050] Example 3:

[0051] This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0052] Adjustment mechanism 28 includes a main body 1 fixedly connected to the bottom of the connecting mechanism 7. A turntable is rotatably sleeved on the outer ring of the main body 1. A gear ring fixedly sleeved on the bottom of the turntable is rotatably sleeved on the outer ring of the main body 1. A gear meshes on one side of the gear ring. A rotating shaft fixedly sleeved on the inner ring of the gear ring is rotatably sleeved on the turntable. A motor is installed at one end of the rotating shaft that extends out of the turntable. An array of L-shaped brackets is fixedly connected to the outer side of the turntable. A docking slot is provided at the bottom of the bracket to engage with the limiting tube 94. Adjustment mechanism 28 has the same structure as adjustment mechanism 15. The docking slot and the limiting tube 94 are engaged by a slot and tooth method. A driven screw is fixedly connected to the bottom of the main body 1 and threadedly sleeved on the sleeve 1 92. The motor drives the gear and gear ring to rotate, thereby causing the main body 1 to drive the driven screw to rotate. Under the action of the thread, the sleeve 1 92 is moved, realizing the position between adjustment mechanism 28 and support locking mechanism 29.

[0053] Example 4:

[0054] like Figure 4 As shown, the base platform 1 includes a base plate 11. The four sides of the top of the base plate 11 are provided with inwardly recessed storage grooves 12. A level 13 is installed inside the storage groove 12 along the length of the adjacent side of the base plate 11. The base plate 11 has through holes 14 for connection and installation. The horizontal position of the base plate 11 after adjustment is determined according to the position of the level 13 located on the four sides of the base plate 11. The holes 14 are distributed in a figure-eight shape with the adjacent row of holes 14.

[0055] This invention employs a modular design, reducing damage and modification operations during the correction process of existing buildings, improving the efficiency of building installation, protecting structural integrity, and mitigating the impact of earthquakes while adjusting uneven building settlement. It enables adjustment operations during building installation, adjusting the building's position to accommodate uneven settlement under different foundation conditions, overcoming the cumbersome and inconvenient adjustment procedures of traditional methods under uneven settlement conditions, and expanding the building's installation adaptability. By using piles and soil to share the load, it enhances the overall bearing capacity. It eliminates dimensional changes caused by thermal expansion or contraction of the building structure, possessing self-adjusting and adaptive functions, and can absorb errors caused by installation errors and foundation tilt.
