Description

Technical Field

[0001] This invention relates to the field of elevator shaft construction technology, and in particular to a modular elevator shaft connection structure and an elevator shaft. Background Technology

[0002] As an indispensable vertical transportation tool in modern buildings, the construction efficiency and quality of elevator shafts directly affect project costs and building functionality. Traditional elevator shaft construction primarily employs on-site casting of reinforced concrete or brick-concrete structures. While this method is technically mature, its construction speed is relatively slow. With the development of industrialized construction, modular construction technology has been introduced into the field of elevator shaft construction. Existing modular elevator shaft solutions, through factory prefabrication of concrete modules, can improve construction speed to some extent. However, these solutions still have shortcomings in the design of the connection structure between shaft modules: most rely on on-site welding or a large number of high-precision bolts for positioning, resulting in a cumbersome installation process, high skill requirements for workers, and difficulty in ensuring rapid and accurate alignment between shaft modules. For these reasons, there is an urgent need for a modular elevator shaft connection structure that is easy to install and ensures accurate alignment.

[0003] It should be noted that the above content is only used to help understand the technical solution of the present invention, and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to propose a modular elevator shaft connection structure and elevator shaft, which aims to achieve convenient installation and ensure accurate alignment.

[0005] To achieve the above objectives, this invention proposes a modular elevator shaft connection structure for interconnecting any two adjacent elevator shaft modules.

[0006] Specifically, the connection structure includes: A connecting sleeve is fixed inside the well module in a vertical direction. The upper end of the connecting sleeve is provided with a first connecting part, and the lower end side of the connecting sleeve is provided with a through hole. A guide positioning component, wherein the first end of the guide positioning component is used to be installed to the upper end of the connecting sleeve, wherein the first end of the guide positioning component is provided with a second connecting portion, and the first connecting portion and the second connecting portion are fixedly connected to each other; the second end of the guide positioning component is used to be inserted into the lower end of the connecting sleeve of another well module, wherein the side of the second end of the guide positioning component is provided with a groove portion arranged circumferentially thereon. A locking pin is horizontally lockable and slidably connected to the well module; the first end of the locking pin is located on the outside of the well module, and the second end of the locking pin can pass through the through hole and extend into the groove to mutually limit the connecting sleeve of another well module and the guide positioning member, thereby connecting two adjacent well modules to each other.

[0007] In one embodiment, the first connecting portion is configured as an internal thread segment, and the second connecting portion is configured as an external thread segment, wherein the internal thread segment and the external thread segment are threadedly engaged.

[0008] In one embodiment, a mounting hole is provided through the center of the guide positioning member, and the mounting hole is arranged radially along the guide positioning member; the mounting hole is used for installing an auxiliary disassembly and assembly tool to rotate the guide positioning member using the auxiliary disassembly and assembly tool.

[0009] In one embodiment, the second end of the guide positioning member has a tapered structure, and the cross-sectional diameter of the guide positioning member gradually decreases towards its second end.

[0010] In one embodiment, the connection structure includes a locking pin sleeve fixedly disposed inside the wellbore module. A first end of the locking pin sleeve is fixedly connected to the lower side of the connecting sleeve, and a second end of the locking pin sleeve is located outside the wellbore module. The locking pin sleeve has a locking pin channel extending through it axially. The locking pin channel is coaxially disposed with the through hole, and the locking pin is slidably connected in the locking pin channel. An elastic element is disposed inside the locking pin channel, and the elastic element applies an elastic force to the locking pin in the direction of the groove.

[0011] In one embodiment, the locking pin channel includes a guide section and an elastic drive section. The cross-sectional diameter of the elastic drive section is larger than that of the guide section, so that a step is formed at the connection between the elastic drive section and the guide section. The guide section is fitted to the outer side of the locking pin. The elastic member is located in the elastic drive section and is sleeved in the middle of the locking pin. A locking pin end is provided at the second end of the locking pin. The cross-sectional diameter of the locking pin end is larger than that of the locking pin. The two ends of the elastic member abut against the step and the locking pin end, respectively.

[0012] In one embodiment, a reset pull ring is provided at the first end of the locking pin, and the reset pull ring abuts against the second end of the locking pin sleeve; In one embodiment, the locking pin end includes a guide head and a locking head connected together, the outer side of the guide head is fitted and connected to the elastic drive section, and the outer side of the locking head is fitted and connected to the groove wall of the groove portion. In one embodiment, the first end of the locking pin sleeve is provided with a fitting portion, which is used to fit and connect with the through hole portion.

[0013] In one embodiment, the well module is provided with a plurality of connecting sleeves inside; correspondingly, the number of the guide positioning member and the locking pin member are provided one-to-one with the number of the connecting sleeves.

[0014] In one embodiment, the mounting surface of one of the shaft modules is provided with a first step structure, and the mounting surface of the other shaft module is provided with a second step structure. When the two shaft modules are connected to each other, the first step structure and the second step structure are in concave-convex fit.

[0015] In one embodiment, a waterproof membrane layer of elastic material is provided between the mounting surfaces of one of the shaft modules and the other shaft module.

[0016] To achieve the above objectives, the present invention proposes an elevator shaft, which includes at least two shaft modules, wherein the at least two shaft modules are stacked, and any two adjacent shaft modules are interconnected by a modular elevator shaft connection structure as described in any of the above claims.

[0017] In one embodiment, the well module is internally fixed with a plurality of horizontally arranged frame stirrups, which are arranged in an array along the vertical direction.

[0018] The technical solution of this invention achieves precise alignment of two adjacent shaft modules through the coordinated operation of a connecting sleeve, a guide positioning component, and a locking pin. Specifically, firstly, the first end of the guide positioning component is fixedly connected to the upper end of the connecting channel using the first and second connecting parts. Then, another shaft module is hoisted above it and slowly lowered. During the descent, the second end of the guide positioning component is aligned and inserted into the lower end of the connecting sleeve of the other shaft module. Finally, the second end of the locking pin passes through the through hole and extends into the groove. The locking pin restricts the relative movement between the guide positioning component and the connecting sleeve of the other shaft module, thereby limiting the connection between the connecting sleeve of the other shaft module and the guide positioning component, thus achieving the interconnection of the two adjacent shaft modules. During the above operation, the insertion and engagement mechanism of the guide positioning component and the connecting sleeve enables the upper and lower well modules to automatically complete alignment and correction during hoisting. Subsequently, the locking pin extends horizontally from the outside of the well module through the through hole and into the groove of the annular structure. This locking method simplifies the traditional multi-point bolt fastening or welding operation into a single tool-based operation, effectively reducing the difficulty of on-site construction and improving the convenience of installation.

[0025] As an indispensable vertical transportation tool in modern buildings, the construction efficiency and quality of elevator shafts directly affect project costs and building functionality. Traditional elevator shaft construction mainly employs on-site casting of reinforced concrete or brick-concrete structures. While this method is technically mature, its construction speed is relatively slow. With the development of building industrialization, modular construction technology has been introduced into the field of elevator shaft construction. Existing modular elevator shaft solutions, through factory prefabrication of concrete modules, can improve construction speed to some extent. However, these solutions still have shortcomings in the design of the connection structure between shaft modules: most rely on on-site welding or a large number of high-precision bolts for positioning, the installation process is cumbersome, requires high levels of worker skill, and it is difficult to guarantee rapid and accurate alignment between shaft modules.

[0026] To address the aforementioned technical problems, this invention proposes a modular elevator shaft connection structure.

[0027] Please see Figures 1 to 5 In one embodiment of the present invention, the modular elevator shaft connection structure is used for the interconnection between any two adjacent shaft modules 10 of the elevator shaft 60. Specifically, the connection structure includes: The connecting sleeve 20 is fixed inside the shaft module 10 in a vertical direction. In this embodiment, the shaft module 10 is formed by concrete casting, and the connecting sleeve 20 is fixed inside the shaft module 10 by pre-embedding. The upper end of the connecting sleeve 20 is provided with a first connecting part 21, and the lower end side of the connecting sleeve 20 is provided with a through hole part 22. The guide positioning component 30 has a first end for mounting to the upper end of the connecting sleeve 20, wherein the first end of the guide positioning component 30 is provided with a second connecting part 31, and the first connecting part 21 and the second connecting part 31 are fixedly connected to each other; the second end of the guide positioning component 30 is used for inserting into the lower end of the connecting sleeve 20 of another well module 10, wherein the side of the second end of the guide positioning component 30 is provided with a groove 32 arranged circumferentially thereon. The locking pin 40 is horizontally lockable and slidably connected to the well module 10. The first end of the locking pin 40 is located on the outside of the well module 10, and the second end of the locking pin 40 can pass through the through hole 22 and extend into the groove 32 to mutually limit the connecting sleeve 20 of another well module 10 and the guide positioning member 30, thereby connecting two adjacent well modules 10 to each other.

[0028] The technical solution of the present invention achieves precise alignment of two adjacent shaft modules 10 through the coordinated cooperation of the connecting sleeve 20, the guide positioning member 30, and the locking pin 40. Specifically, firstly, the first end of the guide positioning member 30 is fixedly connected to the upper end of the connecting channel using the first connecting part 21 and the second connecting part 31. Then, another shaft module 10 is hoisted above it and slowly lowered. During the descent, the second end of the guide positioning member 30 is aligned and inserted into the lower end of the connecting sleeve 20 of the other shaft module 10. Finally, the second end of the locking pin 40 passes through the through hole 22 and extends into the groove 32. The locking pin 40 restricts the relative movement between the guide positioning member 30 and the connecting sleeve 20 of the other shaft module 10, thereby limiting the connection between the connecting sleeve 20 of the other shaft module 10 and the guide positioning member 30, thus achieving the interconnection of two adjacent shaft modules 10. During the above operation, the insertion and engagement mechanism of the guide positioning component 30 and the connecting sleeve 20 enables the upper and lower well modules 10 to automatically complete alignment and correction during hoisting. Subsequently, the locking pin 40 horizontally penetrates the through hole 22 from the outside of the well module 10 and extends to the groove 32 of the annular structure. This locking method simplifies the traditional multi-point bolt fastening or welding operation into a single tool operation, effectively reducing the difficulty of on-site construction and improving the convenience of installation.

[0029] As a preferred embodiment of the above, the first connecting part 21 is configured as an internal thread section, and the second connecting part 31 is configured as an external thread section, with the internal thread section and the external thread section threadedly engaged. This configuration, by configuring the first connecting part 21 and the second connecting part 31 as threadedly engaged internal and external thread sections, achieves a detachable rigid connection between the guide positioning member 30 and the connecting sleeve 20, ensuring connection reliability and facilitating future maintenance and replacement.

[0030] Furthermore, a mounting hole 33 is provided through the center of the guide positioning member 30, and the mounting hole 33 is arranged radially along the guide positioning member 30. The mounting hole 33 is used for installing an auxiliary disassembly tool (not shown in the figure) to rotate the guide positioning member 30 using the auxiliary disassembly tool (such as a steel rod). This arrangement provides a torque application interface for the auxiliary disassembly tool through the radially penetrating mounting hole 33 in the center of the guide positioning member 30, allowing the auxiliary disassembly tool to rotate and thus drive the guide positioning member 30 to rotate accordingly. This enables the first connecting part 21 and the second connecting part 31, which use threaded engagement, to be quickly installed and disassembled, further improving installation convenience.

[0031] As a preferred embodiment, the second end of the guide positioning component 30 has a tapered structure, and the cross-sectional diameter of the guide positioning component 30 gradually decreases towards its second end. This design, with the second end of the guide positioning component 30 being tapered, utilizes the geometric characteristic of its cross-sectional diameter gradually decreasing towards the second end to create a self-aligning effect when the upper and lower shaft modules 10 are joined. Even if there is an initial deviation during hoisting, the tapered surface can automatically guide the shaft module 10 to the correct position, achieving a more efficient automatic correction function. This design significantly reduces the accuracy requirements during the hoisting process of the shaft module 10, reduces the time spent on repeated alignment adjustments, and the tapered mating surface has excellent force transmission performance when bearing horizontal loads, capable of evenly distributing interlayer shear force to the inner wall of the connecting sleeve 20. Compared to traditional cylindrical mating or planar contact, this solution improves installation tolerance while further enhancing the lateral stiffness and stability of the joint, achieving a synergistic optimization effect of construction convenience and structural safety.

[0032] As a preferred embodiment of the above, the connection structure includes a locking pin sleeve 50, which is fixedly disposed inside the wellbore module 10. The first end of the locking pin sleeve 50 is fixedly connected to the lower end side of the connecting sleeve 20, and the second end of the locking pin sleeve 50 is located outside the wellbore module 10. The locking pin sleeve 50 is provided with a locking pin channel 51 that extends through it along its axial direction. The locking pin channel 51 is coaxially disposed with the through hole 22, and the locking pin 40 is slidably connected in the locking pin channel 51. An elastic element 52 is disposed inside the locking pin channel 51, and the elastic element 52 is used to apply an elastic force to the locking pin 40 in the direction of the groove 32. This configuration, by adding a locking pin sleeve 50 fixed inside the shaft module 10 and its internal elastic element 52, constructs an elastic self-locking mechanism. Under the elastic force, the locking pin 40 automatically passes through the through hole 22 and slides into the annular groove 32 of the guide positioning element 30, eliminating the need for manual alignment or hammering, achieving true rapid locking. This design not only simplifies the locking pin operation to a convenient one-handed pull release, greatly shortening the connection time of a single node, but also the continuous force of the elastic element 52 effectively prevents the locking pin 40 from loosening and retracting under vibration or long-term load, significantly improving the fatigue resistance and reliability of the connection node, making it suitable for long-term safe use under continuous vibration conditions during elevator operation. In this embodiment, the elastic element 52 is configured as a compression spring.

[0033] Furthermore, the locking pin channel 51 includes a guide section 511 and an elastic drive section 512. The cross-sectional diameter of the elastic drive section 512 is larger than that of the guide section 511, so that a step portion 513 is formed at the connection between the elastic drive section 512 and the guide section 511. The guide section 511 is fitted and connected to the outer side of the locking pin 40. The elastic element 52 is located in the elastic drive section 512 and is sleeved in the middle of the locking pin 40. The second end of the locking pin 40 is provided with a locking pin end head 41. The cross-sectional diameter of the locking pin end head 41 is larger than that of the locking pin 40. The two ends of the elastic element 52 abut against the step portion 513 and the locking pin end head 41, respectively. This design optimizes the locking pin channel 51 into a variable cross-section structure of guide section 511 and elastic drive section 512. The step portion 513 formed at the connection between the two provides a clear limit for the elastic element 52, ensuring that the direction of the elastic force is always consistent with the axial direction of the locking pin 40, thus avoiding jamming or elastic force attenuation caused by the offset of the elastic element 52. The close fit between the guide section 511 and the outer side of the locking pin 40 ensures the linear accuracy of the locking pin sliding. The layout of the elastic element 52, which is sleeved in the middle of the locking pin 40 and abuts against the step portion 513 and the locking pin end 41 at both ends, achieves efficient transfer and storage of elastic potential energy. This structural design ensures that the locking pin 40 is always subjected to stable axial guidance and elastic drive during installation and reset, significantly improving the working stability and service life of the locking pin mechanism. At the same time, the enlarged diameter design of the locking pin end 41 increases the contact area with the groove portion 32, reduces local stress concentration, and further optimizes the stress performance of the node. Furthermore, the relatively large diameter of the locking pin end 41 prevents it from passing through the guide section 511 of the locking pin channel 51, creating a mechanical self-limiting barrier that fundamentally eliminates the risk of the locking pin 40 accidentally detaching from the locking pin sleeve 50. In the assembled state, the locking pin end 41 is effectively blocked by the step portion 513 between the guide section 511 and the elastic drive section 512, ensuring that the locking pin 40 always remains an integral structure with the locking pin sleeve 50. This integrated design eliminates the cumbersome process of configuring additional anti-detachment parts during on-site installation, enabling the pre-assembled overall installation of the locking pin assembly and further improving construction efficiency.

[0034] Furthermore, a reset pull ring 42 is provided at the first end of the locking pin 40, and the reset pull ring 42 abuts against the second end of the locking pin sleeve 50. With this configuration, the reset pull ring 42 provides a clear point of force for unlocking the locking pin 40 and the wire positioning component. The operator can pull the reset pull ring 42 outward to pull the locking pin 40, thereby achieving quick disassembly of the locking pin 40 and the wire positioning component.

[0035] Furthermore, the locking pin end 41 includes a guide head 411 and a locking head 412 connected together. The outer side of the guide head 411 is fitted and connected to the elastic drive section 512, and the outer side of the locking head 412 is fitted and connected to the groove wall of the groove portion 32. With this configuration, the fitted connection between the outer side of the guide head 411 and the elastic drive section 512 ensures that the locking pin 40 always maintains a precise straight trajectory during axial movement, effectively avoiding jamming and wear problems caused by cantilever force or eccentric sliding, and significantly improving the working stability and durability of the locking pin mechanism. The fitted connection between the outer side of the locking head 412 and the groove wall of the groove portion 32 is specifically responsible for the final locking function. By optimizing the shape and size of the contact surface, the effective pressure bearing area during locking is increased, the contact stress per unit area is reduced, and local damage caused by stress concentration is prevented, while ensuring uniform transmission and reliable engagement of the locking force.

[0036] Furthermore, the locking head 412 has a conical structure, and the cross-sectional diameter of the locking head 412 gradually decreases towards the free end of the locking pin end 41. With this configuration, when the upper shaft module 10 is hoisted and lowered, at the moment the second end of the guide positioning member 30 contacts the locking head 412, the conical surface of the locking head 412 first provides a horizontal component force. This horizontal component force forces the locking pin 40 to slide along the locking pin channel 51 away from the guide positioning member 30 and compress the elastic member 52. As the upper shaft module 10 continues to descend, when the locking head 412 aligns with the groove 32 of the guide positioning member 30, the elastic potential energy accumulated in the elastic member 52 is released instantaneously, driving the locking pin 40 to pop out rapidly, so that its locking head 412 is precisely embedded into the annular groove 32 of the guide positioning member 30, completing self-locking. This dynamic process transforms the manual hole-aligning operation required in traditional assembly into an "avoidance-reset" action automatically driven by conical geometry, achieving interference-free automatic alignment of the locking pin 40 and the groove 32, saving labor costs, and further improving installation convenience.

[0037] Furthermore, the first end of the locking pin sleeve 50 is provided with a fitting portion 53, which is used to fit and connect with the through hole portion 22. This arrangement, with the addition of the fitting portion 53, creates a nested connection between the locking pin sleeve 50 and the through hole portion 22 of the connecting sleeve 20, enhancing the relative positioning rigidity between them and preventing the locking pin channel 51 from misaligning with the through hole portion 22 due to welding deformation or installation deviation, thus avoiding the risk of the locking pin 40 becoming stuck. Understandably, during the welding process between the locking pin sleeve 50 and the connecting sleeve 20, the fitting portion 53 and the through hole portion 22 are used to precisely align the locking pin sleeve 50 and the connecting sleeve 20 before they are welded together.

[0038] As a preferred embodiment of the above, the shaft module 10 is internally provided with a plurality of connecting sleeves 20; correspondingly, the number of guide positioning components 30 and locking pins 40 is set one-to-one with the number of connecting sleeves 20. This arrangement, with multiple corresponding connecting sleeves 20, guide positioning components 30, and locking pins 40 inside the shaft module 10, forms a multi-point distributed connection system. Compared to single-point or few-point connections, this layout evenly distributes inter-layer forces to each connection node, significantly reducing the peak load of a single node and improving the overall stress performance of the shaft structure. Simultaneously, the multi-point synchronous guiding and locking mechanism ensures the coordination of the upper and lower shaft modules 10 across the entire contact surface, avoiding local stress concentration and module warping deformation caused by too few connection points, and significantly improving the geometric stability and verticality accuracy of the shaft module 10. This redundant design also provides valuable safety reserves; even if individual nodes fail unexpectedly, the remaining nodes can still maintain structural integrity, meeting the high reliability requirements of elevator shafts as lifeline engineering projects, and realizing a technological extension from node optimization to system performance improvement.

[0039] As a preferred embodiment of the above, one shaft module 10 has a first step structure 11 on its mounting surface, and the other shaft module 10 has a second step structure 12 on its mounting surface. When the two shaft modules 10 are connected to each other, the first step structure 11 and the second step structure 12 are in a concave-convex fit. This arrangement, by providing the concave-convex fit of the first step structure 11 and the second step structure 12 on the mounting surfaces of adjacent shaft modules 10, significantly enhances the interlayer shear resistance by utilizing the interlocking effect of the concave-convex step structure. This allows the connection node to form multiple force transmission paths when bearing horizontal loads, effectively improving the overall stiffness and lateral resistance of the elevator shaft. More importantly, this concave-convex step structure forms a self-waterproofing system, preventing rainwater from vertically penetrating along the joints of the shaft modules 10, thus solving the waterproofing problem of elevator shafts during long-term outdoor service.

[0040] Furthermore, a waterproof membrane layer 13 of elastic material is provided between the mounting surfaces of one shaft module 10 and another shaft module 10. This arrangement, by adding a waterproof membrane layer 13 of elastic material between the mounting surfaces of adjacent shaft modules 10, forms a dual waterproofing system that combines rigidity and flexibility with the uneven step structure: the elastic waterproof membrane layer 13 undergoes elastic deformation under pressure during module connection, actively compensating for minor gaps in the concrete steps caused by manufacturing tolerances, hoisting errors, and temperature changes, ensuring continuous tightness at the contact interface; compared to traditional sealing methods that rely on on-site adhesive application, the prefabricated embedded waterproof membrane layer 13 avoids the drawbacks of long adhesive curing times and susceptibility to environmental influences on construction quality, achieving efficient "install and seal immediately" operation; simultaneously, the resilience of the elastic material allows it to adapt to repeated vibrations and settlement deformations of the shaft during long-term use, maintaining stable waterproofing performance and significantly reducing the risk of later leakage maintenance; this design organically integrates structural self-waterproofing and material sealing, significantly improving waterproofing durability without increasing complex construction, fully demonstrating the synergistic optimization of functional integration and simplified construction.

[0041] This invention also discloses an elevator shaft 60, which includes at least two shaft modules 10 stacked together. Any two adjacent shaft modules 10 are interconnected using a modular elevator shaft connection structure as described in any of the above embodiments. For the specific structure of the modular elevator shaft connection structure, please refer to the above embodiments. Since this elevator shaft 60 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0042] Further, refer to Figure 6 The shaft module 10 is internally fitted with several horizontally arranged frame stirrups 14, which are arrayed vertically. This arrangement, by arranging several horizontal frame stirrups 14 vertically inside the shaft module 10, constructs a standardized steel reinforcement cage constraint system, significantly enhancing the overall rigidity and deformation resistance of the shaft module 10. More importantly, this stirrup system provides a reliable anchoring foundation for key load-bearing components such as the pre-embedded connecting sleeve 20 and locking pin sleeve 50, ensuring that the nodal load can be evenly distributed to the entire module through the stirrups. This avoids the risk of pre-embedded parts being pulled out or loosened due to insufficient anchoring, achieving an organic unity between the controllability of prefabrication production quality and the reliability of on-site connection. It not only meets the high-efficiency production requirements of mechanized binding in the factory but also fundamentally guarantees the overall safety and durability of the shaft structure.

[0043] As a preferred embodiment of the above embodiments, refer to Figure 7The elevator shaft 60 is divided into shaft modules 10 according to the installation position, namely a base module 61, several first half-floor modules 62, several second half-floor modules 63, and a top seat module 64. Understandably, the base module 61 is located at the lowest end of the elevator shaft 60, and the top seat module 61 is located at the highest end of the elevator shaft 60. The first half-floor modules 62 and the second half-floor modules 63 are combined to form a standard floor module 65.
