Description

Technical Field

[0001] This utility model relates to the field of building foundation reinforcement structure technology, specifically a building foundation reinforcement structure for adding elevators to residential buildings. Background Technology

[0002] CN222614908U discloses a building foundation reinforcement structure for adding elevators to residential buildings. This structure includes strip foundations that connect foundation caps and also connect the foundation caps to the original building foundation. By connecting the foundation caps and the original building foundation with strip foundations, the integrity of the original building foundation and subsequent structures such as foundation caps is effectively improved. This effectively prevents wall cracks during later use, ensuring stable operation. Furthermore, pipe piles are installed at the bottom of the foundation caps.

[0003] When used in conjunction with frame columns, it can provide stable support for the entire building structure, solving the problem that the existing foundation for elevator installation is independent of the foundation of the main building, which leads to weak integrity between the elevator foundation and the main building foundation, and problems such as cracks easily appearing in the walls after the later wall construction is completed.

[0004] The technical solution in the prior art enhances the overall integrity of the elevator foundation and the main building foundation. However, due to differences in construction time and load transfer methods, uneven settlement is likely to occur between the new and old foundations. Although there are strip foundations connecting them, if the differential settlement exceeds the limit, it may still lead to wall cracking or elevator track deformation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foundation reinforcement structure for residential elevator installation, solving the problem of uneven settlement that easily occurs between new and old foundations due to differences in construction time and load transfer methods. Although there is a strip foundation connection, if the settlement difference exceeds the limit, it may still lead to wall cracking or elevator track deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building foundation reinforcement structure for adding elevators to residential buildings, comprising a positioning plate arranged symmetrically on an axis, a positioning block at one end of the positioning plate, a positioning casting block at one end of the positioning block, a plurality of connecting holes on the side of the positioning plate, a positioning rod inserted into the interior of the connecting holes, and through holes on the top surface of both ends of the positioning plate, wherein an anti-settlement component is disposed inside the through holes;

[0007] The anti-settlement component includes a foundation pile fixedly connected to the top surface of the through hole, an extended support rod that penetrates the through hole fixedly connected to the bottom surface of the foundation pile, and an inverted hemisphere fixedly connected to the bottom surface of the extended support rod.

[0008] In one specific embodiment, the two ends of the positioning rod extend into the connection holes of the adjacent positioning plate to form a continuous constraint structure.

[0009] In one specific embodiment, the positioning casting block and the building foundation piles form an integral concrete casting structure.

[0010] In one specific embodiment, the extended support rod is an integral steel structure that extends continuously in a single section to the bearing layer of the foundation.

[0011] In one specific embodiment, the bottom surface of the inverted hemisphere is provided with radially distributed reinforcing ribs.

[0012] In one specific embodiment, the top of the foundation pile is provided with an array of bolt positioning holes for elevator frame installation.

[0013] Compared with the prior art, this utility model provides a building foundation reinforcement structure for adding elevators to residential buildings, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, the foundation bearing capacity is strengthened and settlement is suppressed by combining the extended support rod of the anti-settlement component with the inverted hemisphere.

[0015] The anti-settlement component designed in this invention uses positioning rods that penetrate multiple connecting holes on the sides of the positioning plates to form a lateral constraint network. This network, combined with the positioning casting blocks at the positioning blocks, integrates with the original building foundation for longitudinal anchoring. Simultaneously, the extended support rods of the anti-settlement component pass through the through holes at the top of the positioning plates, reaching the bearing layer of the foundation. The inverted hemispheres at their ends, along with the radial ribs, work together to expand the foundation's bearing area. The bolt positioning hole array at the top of the foundation piles precisely aligns with the elevator frame. These interconnected structures form a three-dimensional constraint system, ultimately eliminating differential settlement between the old and new foundations and preventing the risk of wall cracking.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 As an embodiment of this utility model, a building foundation reinforcement structure for adding elevators to residential buildings includes a positioning plate 1 arranged symmetrically on an axis, a positioning block 2 at one end of the positioning plate 1, a positioning casting block 3 at one end of the positioning block 2, a plurality of connecting holes on the side of the positioning plate 1, a positioning rod 4 inserted into the connecting holes, and through holes on the top surface of both ends of the positioning plate 1, with anti-settlement components 5 installed inside the through holes.

[0024] The specific problem addressed in this embodiment is to solve the issue of uneven settlement that easily occurs between new and old foundations due to differences in construction time and load transfer methods. Even with strip foundation connections, if the settlement difference exceeds the limit, it can still lead to wall cracking or elevator track deformation. This utility model utilizes the combination of the extended support rod 52 and the inverted hemisphere 53 of the anti-settlement component 5 to strengthen the foundation bearing capacity and suppress settlement.

[0025] The anti-settlement component 5 includes a foundation pile 51 fixedly connected to the top surface of the through hole. An extended support rod 52, penetrating the through hole, is fixedly connected to the bottom surface of the foundation pile 51. An inverted hemisphere 53 is fixedly connected to the bottom surface of the extended support rod 52. In this specific embodiment, the extended support rod 52 is a single-section, continuous steel structure extending to the bearing layer of the foundation. Positioning rods 4 penetrate multiple connecting holes on the sides of positioning plates 1 to form a transverse constraint network. This network, combined with the positioning casting block 3 at the positioning block 2, integrates with the original building foundation for longitudinal anchoring. Simultaneously, the extended support rod 52 of the anti-settlement component 5 passes through the through hole at the top of the positioning plate 1, reaching the bearing layer of the foundation. The inverted hemisphere 53 at its end, along with radial ribs, works synergistically to expand the foundation's bearing area. The bolt positioning hole array at the top of the foundation pile 51 precisely connects with the elevator frame. These interconnected structures form a three-dimensional constraint system, ultimately eliminating differential settlement between the old and new foundations and preventing the risk of wall cracking.

[0026] In this specific embodiment, the bottom surface of the inverted hemisphere 53 is provided with radially distributed reinforcing ribs; the bottom surface of the inverted hemisphere 53 is welded with radially distributed reinforcing ribs with the center as the origin, the ribs have a triangular cross section and extend radially along the hemispherical surface to the edge, and when their bottom is embedded in the bearing layer of the foundation, a multi-directional interlocking structure is formed; this design divides the soil stress zone by ribs and increases the pull-out contact area, so that the settlement of the inverted hemisphere 53 under vertical load is reduced, the horizontal displacement restraint capacity is improved, and the deformation resistance of the new and old foundations is significantly enhanced.

[0027] In this specific embodiment, the top of the foundation pile 51 is provided with an array of bolt positioning holes for elevator frame installation; the top of the foundation pile 51 is milled by a CNC machine tool to form the bolt positioning hole array, the hole positions are arranged at equal intervals according to the elevator frame installation reference points and anti-loosening threaded sleeves are pre-embedded; this structure enables the elevator frame and the foundation pile 51 to achieve millimeter-level positioning assembly through high-strength bolts, eliminating stress concentration caused by traditional welding, while reserving dynamic leveling allowance to ensure the first-time pass rate of elevator track installation and reduce the frequency of subsequent maintenance.

[0028] Working principle: During construction, the axisymmetrically arranged positioning plates 1 are attached to the original foundation of the building. The positioning blocks 3 at the positioning blocks 2 are cast in place with the original foundation to form a permanent anchor. At the same time, the connecting holes on the sides of multiple positioning plates 1 are penetrated by positioning rods 4 to form a lateral constraint network. The foundation piles 51 of the anti-settlement component 5 are fixed at the through holes at the top of the positioning plates 1, and their extended support rods 52 are anchored into the bearing layer of the foundation through the through holes. The inverted hemispheres 53 at the bottom of the extended support rods 52 expand the bearing area by using the curved surface, and the radial ribs at the bottom are embedded in the soil to enhance the pull-out resistance. The elevator load is transferred to the extended support rods 52 through the bolt positioning hole array at the top of the foundation piles 51, and finally evenly distributed to the bearing layer by the inverted hemispheres 53. The lateral positioning rods 4 constrain the structural offset, and the longitudinal positioning blocks 3 inhibit the separation of the old and new foundations, so as to achieve three-dimensional coordinated settlement control.

[0029] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
