Description

Technical Field

[0001] This invention belongs to the field of vertical component positioning and installation technology, specifically relating to a positioning device for vertical components and its installation method. Background Technology

[0002] I-beam vertical members refer to vertically erected steel columns with an I-beam cross-section. As the core vertical load-bearing members of a steel structure, they primarily bear axial pressure and bending moment, reliably transferring the upper load to the foundation. Their cross-section is I-shaped, consisting of upper and lower flanges and a central web. The flanges concentrate material away from the neutral axis, resulting in high bending efficiency; the web is thin yet strong, primarily bearing shear force and connecting the flanges, achieving a balance between lightweight and high load-bearing capacity.

[0003] Traditional steel structure vertical members are installed using lugs and connecting plates on both sides of the joints for temporary positioning and adjustment. This installation method suffers from several drawbacks. The lugs have relatively low rigidity and are easily deformed by impacts with the steel members, affecting adjustment accuracy. Furthermore, the lack of vertical positioning measures means that welding backing plates often detach due to impacts, making it difficult to guarantee the welding quality of the first-level welds on the butt joints of vertical members.

[0004] Existing patent (publication number: CN115419282B) discloses an installation device and construction method for vertical members of steel structures. The installation device for vertical members of steel structures of this invention improves the rigidity of the lugs of the vertical members by using attached lugs, preventing deformation due to collisions during positioning and improving adjustment accuracy. Furthermore, vertical positioning is achieved by supporting components between the lugs of the upper and lower column sections, preventing vertical collisions during positioning that could cause welding pads to detach or deform, thus ensuring the quality of the weld.

[0005] To address the aforementioned issues, while existing patents offer solutions for vertical positioning through the cooperation of components such as ear plates, the overall installation process is cumbersome and time-consuming, exhibiting significant shortcomings in practical applications: the entire process relies on manual operation, requiring multi-step adjustments, and manual leveling with pads is necessary for high-altitude work. This not only heavily depends on the operator's measurement accuracy and on-site experience, leading to significant human error, but also results in cumbersome and inefficient positioning and calibration processes, resulting in slow overall installation and positioning speeds, which is detrimental to improving construction efficiency and operational safety. Summary of the Invention

[0006] This invention provides a positioning device for vertical components and its installation method, solving the technical problem of crimping cable harnesses and terminals in related technologies.

[0007] The present invention provides a positioning device for a vertical component and its installation method, comprising an upper component and a lower component disposed below the upper component, wherein positioning holes for engaging are provided on the inner walls of both the upper component and the lower component;

[0008] A positioning mechanism for initial positioning is provided between the upper component and the lower component, and a reinforcement mechanism for further improving positioning stability is provided on one side of the positioning mechanism on the outer wall of the upper component, and a stabilizing mechanism for improving the overall docking stability is provided on the other side of the positioning mechanism on the outer wall of the upper component.

[0009] In a preferred embodiment, the positioning mechanism includes an assembly plate that is slidably connected to the outer wall of the upper component, and connecting blocks are fixedly installed at both ends of the assembly plate. A fixed cylinder for guidance is fixedly installed on the outer wall of the connecting block, and a through rod extends out of the inside of the fixed cylinder.

[0010] In a preferred embodiment, a contact plate for clamping the upper component is fixedly installed at one end of the protruding rod through the fixed cylinder, and reinforcing plates are fixedly installed on both sides inside the fixed cylinder, with a deformation memory alloy body embedded between the reinforcing plates.

[0011] In a preferred embodiment, a through-post for positioning is fixedly installed on the side of the contact plate facing the upward component, and a heat insulation pad is embedded at one end of the fixing cylinder.

[0012] In a preferred embodiment, the reinforcement mechanism includes a through hole formed on the inner wall of the connecting block, and an extension rod extending through the through hole, wherein a through rod for reinforcing the connection extends through the extension rod.

[0013] In a preferred embodiment, the stabilizing mechanism includes an abutment rod that extends through the interior of the abutment plate, and one end of the abutment rod is fitted with an abutment cylinder, the interior of which is provided with a storage cavity for reserving space for the abutment rod.

[0014] In a preferred embodiment, a locking block is fixedly installed on the outer wall of one end of the abutment rod that penetrates into the storage cavity, and a sliding groove is provided on the outer wall of the abutment cylinder at the position corresponding to the locking block, and a locking groove is provided at one end of the sliding groove.

[0015] In a preferred embodiment, one end of the abutment rod is fixedly equipped with an arc-shaped head that facilitates insertion into the space, and the outer wall of the abutment plate is provided with an abutment hole corresponding to the position of the arc-shaped head.

[0016] In a preferred embodiment, an abutment ring is slidably connected to the outside of the abutment cylinder, and a limiting groove is formed on the inner wall of the abutment ring. A through block for pressing the abutment rod is rotatably connected inside the limiting groove, and a push block is fixedly installed at one end of the through block.

[0017] This invention provides a method for installing a positioning device for vertical components:

[0018] S1: Adjust the assembly plate of the positioning mechanism so that it slides along the outer wall of the upper component and aligns with the preset positioning hole positions of the upper and lower components.

[0019] S2: The fixed cylinder, which is fixed to the connecting block, is directionally heated by a hot air blower or a special handheld heating device. This causes the built-in deformation memory alloy to shrink and deform under heat, which in turn causes the fixed cylinder and the through rod to shrink synchronously. This drives the contact plate to move toward the assembly plate, so that the through column can be accurately inserted into the pre-set positioning holes of the upper and lower components, thus completing the rapid preliminary positioning between the components.

[0020] S3: During the displacement of the contact plate, the extension rod is extended through the through hole on the connecting block, and then the through rod passes through the extension rod to form a threaded locking connection, which constitutes an auxiliary reinforcement structure, realizes double limit in the positioning stage, and prevents the deformation memory alloy body from resetting and springing back due to the temperature drop of the preheating component.

[0021] S4: After the positioning mechanism and the reinforcement mechanism have completed the initial assembly and positioning, the two ends of the telescopic rod assembly, which consists of the contact rod and the contact cylinder, are respectively inserted into the corresponding contact plates through the contact holes to achieve docking.

[0022] S5: The tensioning rod slides along the receiving cavity to extend, so that the locking block slides into place along the slide groove and then rotates to lock into the slot, completing the self-locking initial locking of the telescopic rod, preventing it from loosening and retracting after extension, and forming stable support for the two side contact plates.

[0023] S6: Rotate the contact ring that is threaded with the contact cylinder, so that it forms a sliding engagement constraint with the through block through the limiting groove. During the rotational feeding along the contact cylinder, it drives the jacking block to move synchronously and press tightly against the side wall of the contact rod, applying a stable clamping force to the locking block and strengthening the overall locking effect.

[0024] S7: Repeat steps S1 to S6 to complete the assembly of multiple sets of positioning and reinforcement mechanisms, ensuring the stability and consistency of the continuous assembly process.

[0025] S8: Confirm that all components are assembled in place, check that the vertical connection between the upper and lower components is secure and without gaps, and complete the overall vertical component assembly.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention utilizes a built-in deformation memory alloy body that is heated and then shrinks, causing the fixed cylinder and the through rod to shrink synchronously. This drives the contact plate to move towards the assembly plate, allowing the through column to be precisely inserted into the preset positioning hole. This enables rapid initial positioning of the component, eliminating bolt connections and on-site welding, significantly simplifying the assembly process, shortening construction time, and significantly improving overall assembly efficiency. Furthermore, the threaded locking of the through rod forms an auxiliary reinforcement structure, achieving dual limiting during the positioning stage. This prevents the deformation memory alloy body from springing back due to a drop in temperature in the pre-heated components, ensuring a stable and reliable continuous assembly process.

[0028] This invention utilizes a telescopic rod composed of an abutment rod and an abutment cylinder, with both ends connected to corresponding abutment plates via abutment holes. The stretched abutment rod extends along the receiving cavity, and the locking block slides along the groove and screws into the slot, achieving self-locking engagement of the telescopic rod. This prevents loosening and retraction, provides stable support to the abutment plates on both sides, counteracts the restoring stress of the deformation shape memory alloy, avoids loosening of the joint structure, and improves the stability of the vertical splicing structure. The rounded end of the abutment rod reduces the difficulty of inserting it into the abutment hole, making assembly smoother. After engagement, rotating the abutment ring, which is threaded into the abutment cylinder, causes the abutment ring to slide through a limiting groove and a through-block, driving the jacking block to press against the side wall of the abutment rod, achieving axial positioning and clamping the locking block, thus enhancing the locking effect. This reduces fasteners and disassembly / reassembly steps, improves the overall structural integrity and connection reliability, optimizes the assembly process, and achieves efficient, stable, and convenient assembly of vertical components.

[0037] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Example 1

[0039] like Figures 1 to 5 As shown, a positioning device for a vertical component and its installation method include an upper component 1 and a lower component 2 below the upper component 1. Positioning holes 3 for engagement are provided on the inner walls of both the upper component 1 and the lower component 2. A positioning mechanism 4 for initial positioning is provided between the upper component 1 and the lower component 2. A reinforcing mechanism 5 for further improving positioning stability is provided on one side of the positioning mechanism 4 on the outer wall of the upper component 1, and a stabilizing mechanism 6 for improving overall docking stability is provided on the other side of the positioning mechanism 4 on the outer wall of the upper component 1. The positioning mechanism 4 includes an assembly plate 401, which is slidably connected to the outer wall of the upper component 1. Connecting blocks 402 are fixedly installed at both ends of the assembly plate 401, and guides are fixedly installed on the outer walls of the connecting blocks 402. The fixed cylinder 403 has a through rod 404 extending through it. One end of the through rod 404 is fixedly installed with a contact plate 405 for clamping the upper component 1. Reinforcing plates 406 are fixedly installed on both sides of the fixed cylinder 403. A deformation memory alloy body 407 is embedded between the reinforcing plates 406. A through post 408 for positioning is fixedly installed on the side of the contact plate 405 facing the upper component 1. A heat insulation pad 409 is embedded at one end of the fixed cylinder 403. The reinforcement mechanism 5 includes a through hole 501, which is opened on the inner wall of the connecting block 402. An extension rod 502 extends through the through hole 501, and a through rod 503 for reinforcing connection extends through the extension rod 502.

[0040] When the upper component 1 and the lower component 2 are vertically aligned, the assembly plate 401 is first pushed to slide against the upper component 1 to the corresponding position. Then, a hot air blower or a handheld adapter heating device is used to heat the fixing cylinder 403 fixed on the connecting block 402, causing the built-in deformation memory alloy body 407 to shrink due to heat. This causes the fixing cylinder 403 and the through rod 404 to shrink synchronously, thereby pushing the contact plate 405 to move towards the assembly plate 401. This allows the through rod 408 to accurately penetrate the pre-set positioning holes 3 of the upper component 1 and the lower component 2 to complete the initial positioning. At the same time, as the contact plate 405 moves, the extension rod 502 passes through the through hole 501 and through the connecting block 402, and then through the extension rod 503. The rod 502 is threaded and locked to achieve secondary reinforcement and limiting. The deformation memory alloy body 407 is driven by heat shrinkage, replacing the traditional cumbersome processes such as bolt connection and welding, which greatly improves positioning efficiency and reduces operation complexity. The guiding role of the assembly plate 401 and the support and fixation of the deformation memory alloy body 407 by the reinforcing plate 406 can effectively ensure positioning accuracy and driving stability. In conjunction with the heat insulation pad 409 to isolate the heating heat, it can avoid component deformation and performance damage due to heat, ensuring the structural integrity of the component and assembly quality. The cooperation between the extended rod 502 and the through rod 503 can reliably reinforce and limit, preventing loosening during assembly, and further ensuring assembly stability and pass rate.

[0041] Example 2

[0042] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a positioning device for a vertical component and its installation method are disclosed. The stabilizing mechanism 6 includes an abutment rod 601 that extends through the interior of an abutment plate 405. One end of the abutment rod 601 is fitted with an abutment cylinder 602. The abutment cylinder 602 has a storage cavity 603 for reserving space for the abutment rod 601. A locking block 604 is fixedly installed on the outer wall of the end of the abutment rod 601 that enters the storage cavity 603. A sliding groove 605 is provided on the outer wall of the abutment cylinder 602 corresponding to the position of the locking block 604. One end of 605 is provided with a slot 606, and one end of the abutment rod 601 is fixedly installed with an arc head 607 that is easy to pass through the space. The outer wall of the abutment plate 405 is provided with an abutment hole 608 corresponding to the position of the arc head 607. The outer side of the abutment cylinder 602 is slidably connected with an abutment ring 609. The inner wall of the abutment ring 609 is provided with a limit groove 610. The limit groove 610 is rotatably connected with a through block 611 for pressing the abutment rod 601. One end of the through block 611 is fixedly installed with a push block 612.

[0043] The telescopic rod, consisting of the abutment rod 601 and the abutment cylinder 602, is inserted into the corresponding abutment plate 405 through the abutment hole 608 at both ends. The abutment rod 601 is stretched so that it slides along the receiving cavity 603. After the locking block 604 moves into place along the sliding groove 605, it is rotated into the locking groove 606 to achieve pre-locking. This can effectively prevent the telescopic rod from loosening after it is extended, and form a reliable support for the abutment plates 405 on both sides. It counteracts the loosening tendency caused by the room temperature recovery force of the deformation memory alloy body 407, and improves the overall stability of the splicing structure. The rounded head 607 at the end of the abutment rod 601 can reduce the assembly resistance of inserting it into the abutment hole 608 and achieve smooth insertion. Subsequently, the abutment ring 609, which is threadedly engaged with the abutment cylinder 602, is rotated. The abutment ring 609 is slidably limited by the limiting groove 610 and the through block 611. During its rotation, it drives the jacking block 612 to move synchronously and press against the side of the abutment rod 601. The threaded engagement structure has a self-locking characteristic, which can form a stable clamping constraint on the locking block 604, further enhancing the overall connection rigidity and anti-loosening ability. This structure abandons the traditional bolt fastening method, and the assembly process is simple and efficient. While simplifying the disassembly and assembly process, it significantly improves the splicing positioning accuracy, structural stability and reliability.

[0044] This invention provides a method for installing a positioning device for vertical components:

[0045] S1: Adjust the assembly plate 401 of the positioning mechanism 4 so that it slides along the outer wall of the upper component 1 and aligns with the preset positioning hole 3 positions of the upper component 1 and the lower component 2.

[0046] S2: The fixed cylinder 403, which is fixed to the connecting block 402, is directionally heated by a hot air blower or a special handheld heating device, so that the built-in deformation memory alloy body 407 shrinks and deforms due to heat, which drives the fixed cylinder 403 and the through rod 404 to shrink synchronously, driving the contact plate 405 to move towards the assembly plate 401, so that the through column 408 is accurately inserted into the pre-set positioning hole 3 of the upper component 1 and the lower component 2, and the rapid preliminary positioning between components is completed.

[0047] S3: During the displacement of the contact plate 405, the extension rod 502 is extended through the through hole 501 on the connecting block 402, and then the through rod 503 passes through the extension rod 502 to form a threaded locking connection, which constitutes an auxiliary reinforcement structure, realizes double limit in the positioning stage, and prevents the deformation memory alloy body 407 from resetting and springing back due to the temperature drop of the preheating component.

[0048] S4: After the positioning mechanism 4 and the reinforcement mechanism 5 have completed the initial assembly and positioning, the two ends of the telescopic rod assembly composed of the contact rod 601 and the contact cylinder 602 are respectively inserted into the corresponding contact plate 405 through the contact hole 608 to achieve docking.

[0049] S5: The tensioning rod 601 slides and extends along the receiving cavity 603, so that the locking block 604 slides into place along the sliding groove 605 and rotates to lock into the locking slot 606, completing the self-locking initial locking of the telescopic rod, preventing it from loosening and retracting after extension, and forming stable support for the two side contact plates 405.

[0050] S6: Rotate the abutment ring 609 that is threadedly engaged with the abutment cylinder 602, so that it forms a sliding engagement constraint with the through block 611 through the limiting groove 610. During the rotational feeding along the abutment cylinder 602, the jacking block 612 is driven to move synchronously and press tightly against the side wall of the abutment rod 601, applying a stable clamping force to the locking block 604 and strengthening the overall locking effect.

[0051] S7: Repeat steps S2 to S6 to complete the assembly of multiple sets of positioning mechanisms 4 and reinforcement mechanisms 5, ensuring the stability and consistency of the continuous assembly process.

[0052] S8: Confirm that all components are assembled in place, check that the vertical connection between the upper component 1 and the lower component 2 is secure and without gaps, and complete the overall vertical component assembly.

[0053] Working principle: When the upper component 1 and the lower component 2 are vertically assembled, the assembly plate 401 can slide along the outer wall of the upper component 1. The fixed cylinder 403, which is fixed to the connecting block 402, is directionally heated by a hot air blower or a special handheld heating device. This causes the built-in deformation memory alloy body 407 to shrink and deform due to the heat, which drives the fixed cylinder 403 and the through rod 404 to shrink synchronously. This, in turn, drives the contact plate 405 to move towards the assembly plate 401, so that the through column 408 can be accurately inserted into the pre-set positioning hole 3 of the upper component 1 and the lower component 2, realizing rapid preliminary positioning between the components. The reinforcing plate 406 provides reliable support and limit constraint for the deformation memory alloy body 407 from both sides, and works with the heat insulation pad 409 to block heat transfer during the heating process. This guide method avoids the thermal impact of high temperature on the upper component 1 and lower component 2. This positioning method does not require bolt connection or on-site welding, which can significantly simplify the assembly process, shorten the operation time, and effectively improve the overall assembly efficiency. During the displacement of the contact plate 405, the extension rod 502 extends through the through hole 501 on the connecting block 402, and then the through rod 503 passes through the extension rod 502 to form a threaded locking connection, which constitutes an auxiliary reinforcement structure. It can achieve double limit during the positioning stage, preventing the early heated components from returning to their original position due to temperature drop when heating multiple sets of deformation memory alloy bodies 407 in the subsequent heating operations. This avoids the increase of assembly gap or positioning failure, and ensures the stability and consistency of the continuous assembly process.

[0054] After the positioning mechanism 4 and the reinforcing mechanism 5 complete their initial assembly and positioning, the telescopic rod assembly, consisting of the abutment rod 601 and the abutment cylinder 602, is inserted into the corresponding abutment plates 405 through the abutment holes 608 at both ends to achieve docking. During the process of the stretched abutment rod 601 sliding along the receiving cavity 603, the locking block 604 slides into place along the slide groove 605 and then rotates into the locking slot 606, completing the self-locking initial engagement of the telescopic rod. This prevents loosening and retraction after extension, provides stable support to the abutment plates 405 on both sides, counteracts the reset stress generated during the room temperature recovery process of the deformation memory alloy body 407, and forms mutual abutment force to prevent the overall docking structure from loosening. This further improves the structural stability after vertical splicing. The rounded end 607 of the abutment rod 601 can reduce the insertion of the abutment hole 608. To improve assembly smoothness, after the engagement is completed, the rotating contact ring 609, which is threadedly engaged with the contact cylinder 602, forms a sliding engagement constraint with the through block 611 through the limiting groove 610. During the rotational feeding along the contact cylinder 602, the contact ring 609 drives the jacking block 612 to move synchronously and press tightly against the side wall of the contact rod 601. The contact ring 609 forms a reliable axial positioning through the threaded connection, applying a stable clamping force to the locking block 604, further enhancing the overall locking effect. This eliminates the traditional bolt fastening method, reduces the number of fasteners and disassembly steps, and effectively solves the problem of cumbersome procedures and complex operations when assembling multiple components. While improving the overall structural integrity and connection reliability, it further optimizes the assembly process and achieves efficient, stable, and convenient vertical component docking assembly.

[0055] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

The installation method of a positioning device for a vertical component according to claim 9, characterized in that, S1: Adjust the assembly plate (401) of the positioning mechanism (4) so ​​that it slides along the outer wall of the upper component (1) and aligns with the preset positioning hole (3) positions of the upper component (1) and the lower component (2); S2: The fixed cylinder (403) fixed to the connecting block (402) is directionally heated by a hot air blower or a special handheld heating device, so that the built-in deformation memory alloy body (407) shrinks and deforms due to heat, which drives the fixed cylinder (403) and the through rod (404) to shrink synchronously, driving the contact plate (405) to move towards the assembly plate (401), so that the through column (408) is accurately inserted into the pre-set positioning hole (3) of the upper component (1) and the lower component (2), and the rapid preliminary positioning between components is completed; S3: During the displacement of the contact plate (405), the extension rod (502) is extended through the through hole (501) on the connecting block (402), and then the through rod (503) passes through the extension rod (502) to form a threaded locking connection, which constitutes an auxiliary reinforcement structure, realizes double limit in the positioning stage, and prevents the deformation memory alloy body (407) from resetting and springing back due to the temperature drop of the early heating component; S4: After the positioning mechanism (4) and the reinforcement mechanism (5) have completed the initial assembly and positioning, the two ends of the telescopic rod assembly composed of the contact rod (601) and the contact cylinder (602) are respectively inserted into the corresponding contact plate (405) through the contact hole (608) to achieve docking; S5: The tensioning rod (601) slides and extends along the receiving cavity (603), so that the locking block (604) slides and moves into place along the slide groove (605) and rotates and locks into the locking groove (606), completing the self-locking initial locking of the telescopic rod, preventing it from loosening and retracting after extension, and forming a stable support for the two side contact plates (405). S6: Rotate the contact ring (609) that is threadedly engaged with the contact cylinder (602), so that it forms a sliding engagement constraint with the through block (611) through the limiting groove (610). During the rotational feeding along the contact cylinder (602), it drives the jacking block (612) to move synchronously and press tightly against the side wall of the contact rod (601), applying a stable clamping force to the locking block (604) and strengthening the overall locking effect. S7: Repeat steps S2 to S6 to complete the assembly of multiple sets of positioning mechanisms (4) and reinforcement mechanisms (5) to ensure the stability and consistency of the continuous assembly process; S8: Confirm that all components are assembled in place, check that the upper component (1) and the lower component (2) are vertically connected without looseness or gaps, and complete the overall vertical component connection assembly.
