Description

Technical Field

[0001] This utility model relates to the field of disc-lock scaffolding, specifically a disc-lock scaffolding upright connecting foot sleeve for construction. Background Technology

[0002] Disc-lock scaffolding is a modular building support system that uses pin-connected uprights, horizontal bars, and diagonal braces to form a stable structure. It has advantages such as high strength, high load-bearing capacity, and quick assembly and disassembly. Its disc nodes enable multi-point force distribution, and the diagonal braces enhance resistance to lateral displacement. It is suitable for high-rise buildings, bridges, stage construction, and other scenarios, and the hot-dip galvanizing process improves its durability.

[0003] Currently, disc-lock scaffolding is one of the main types of scaffolding, with advantages such as convenient assembly and quick connection. However, a problem exists in actual use: the disc-lock scaffolding is currently fixed to the external scaffolding pipes by welding. During actual assembly, the mounting holes on the disc-lock scaffolding do not align with the installation angles of the external scaffolding connectors. This necessitates reinstalling the disc-lock scaffolding and its pipes, and adjusting the installation angle of the disc-lock scaffolding. This undoubtedly reduces the ease of assembly for operators. Therefore, the inventor urgently needs to design a disc-lock scaffolding adjustment mechanism to improve the ease and efficiency of installation of disc-lock scaffolding. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a connecting sleeve for the uprights of a disc-lock scaffold in construction, so as to solve the technical problem of difficulty in adjusting the installation angle of disc-lock scaffold due to welding and fixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connecting sleeve for uprights of a construction scaffold using a disc buckle, comprising an installation tube, a disc buckle being movably sleeved on the outer side of the installation tube, a positioning mechanism being provided between the lower part of the disc buckle and the outer wall of the installation tube, the positioning mechanism comprising a limiting plate, the limiting plate being welded and fixed to the installation tube, a plurality of inserts being arranged in a ring above the limiting plate, slots being provided on the surface of the disc buckle at positions opposite to the inserts, the number of slots being the same as the number of inserts, and a pressing mechanism for limiting the position of the disc buckle being provided on the outer side of the installation tube above the disc buckle.

[0006] By adopting the above technical solution, and through the separate setting of the installation pipe and the movable disc buckle, the limitations of traditional welding and fixing are broken, allowing the disc buckle to be freely rotated and adjusted according to actual construction needs.

[0007] Furthermore, the disc buckle is connected to the limiting plate via a plug and a slot to fix the angle of the disc buckle.

[0008] By adopting the above technical solution, the precise angular positioning of the disc buckle and the limiting plate is achieved through the plug-in cooperation of the plug and the slot. This setting allows construction personnel to quickly lock the disc buckle at multiple preset angular positions.

[0009] Furthermore, the pressing mechanism includes a pressing sleeve and a rotating sleeve, the pressing sleeve and the rotating sleeve are fixedly connected, the rotating sleeve is threadedly connected to the outer side of the mounting tube, and the pressing sleeve abuts against the disc buckle.

[0010] By adopting the above technical solution, the threaded pressing mechanism drives the pressing sleeve to move axially by rotating the sleeve, thereby achieving linear pressing of the disc buckle. This mechanical pressing method can generate uniform and continuous preload.

[0011] Furthermore, the pressing mechanism also includes a fixed sleeve, which is fixedly connected to the mounting tube. The inner side of the fixed sleeve has a slot with an opening on one side, and a movable sleeve is movably arranged inside the slot. A manganese steel pressure spring is elastically connected between the upper part of the movable sleeve and the inner side of the slot.

[0012] By adopting the above technical solution, the elastic pressing mechanism provides continuous downward pressure to the movable sleeve through the manganese steel pressure spring, which can automatically compensate for the gap changes caused by the wear of parts or temperature changes, and maintain a constant clamping force on the disc buckle.

[0013] Furthermore, the lower end of the movable sleeve abuts against the disc buckle via a pressure spring, and a fixing ring is provided on the outer side of the movable sleeve, which is the point where the operator applies force to the movable sleeve.

[0014] By adopting the above technical solution, the fixing ring set on the outside of the movable sleeve provides the operator with a clear point of force application, which facilitates height adjustment by tools or manual means, and conforms to the principles of ergonomic design.

[0015] Furthermore, sleeves are welded and fixed to the outer sides of both the upper and lower ends of the mounting tube.

[0016] By adopting the above technical solution, the sleeves welded at both ends of the installation pipe form a standardized connection interface, which can be quickly plugged into and assembled with poles of different specifications, simplifying the complexity of matching poles on site.

[0017] Furthermore, the outer diameter of the mounting tube is 48mm, and the outer diameter of the sleeve is 60mm.

[0018] By adopting the above technical solution, the installation pipe is set with a 48mm outer diameter and the sleeve with a 60mm outer diameter, which not only ensures compatibility with commonly used scaffolding uprights, but also achieves a smooth transition in the connection area through the stepped structure.

[0019] In summary, the present invention has the following main advantages: This utility model achieves free angle adjustment of the disc buckle through the movable sleeve structure of the mounting tube and the disc buckle, solving the problem that traditional welded disc buckles need to be completely disassembled and adjusted due to hole position deviations. At the same time, the insertion and engagement of the insert block and slot in the positioning mechanism provides multi-angle positioning capability, ensuring rapid locking and avoiding the risk of welding fatigue. Meanwhile, the pressing mechanism adopts a threaded drive or elastic clamping mechanism: the threaded pressing sleeve provides mechanical self-locking clamping force, while the manganese steel pressure spring with elastic structure can automatically compensate for gap changes, adapt to load vibration and temperature deformation, and significantly enhance the stability of the joint.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: A type of disc-lock scaffolding upright connecting sleeve for construction, such as Figure 1-5As shown, the device includes an installation tube 1, with a disc buckle 3 movably sleeved on the outer side of the installation tube 1. A positioning mechanism 4 is provided between the lower part of the disc buckle 3 and the outer wall of the installation tube 1. The positioning mechanism 4 includes a limiting plate 401, which is welded and fixed to the installation tube 1. Several inserts 402 are arranged in a ring above the limiting plate 401. The surface of the disc buckle 3, opposite to the position of the inserts 402, has slots 403 in the same number as the number of inserts 402. A pressing mechanism 5 is provided on the outer side of the installation tube 1, above the disc buckle 3, to limit the position of the disc buckle 3. By separating the installation tube 1 from the movably sleeved disc buckle 3, the limitations of traditional welding fixation are overcome, allowing the disc buckle to be freely rotated and adjusted according to actual construction needs. At the same time, the synergistic effect of the positioning mechanism 4 and the pressing mechanism 5 forms a double locking mechanism, which ensures both the flexibility of angle adjustment and the structural stability under load. This effectively solves the problem of repeated disassembly and assembly caused by hole position deviation in the prior art, significantly improving construction efficiency and reducing labor intensity.

[0024] See Figure 1 , Figure 2 , Figure 3 The disc buckle 3 is connected to the limiting plate 401 via the insert block 402 and the slot 403 to fix the angle of the disc buckle 3. Through the insertion and cooperation of the insert block 402 and the slot 403, the disc buckle 3 and the limiting plate 401 are precisely positioned at an angle. This setting allows construction personnel to quickly lock the disc buckle at multiple preset angle positions. At the same time, this mechanical interlocking structure avoids the risk of fatigue cracking common in welded connections, enhances the durability of the node under cyclic load, and the plug-in design can be adjusted without special tools, which significantly improves the adaptability and reliability of on-site operation.

[0025] See Figure 1 , Figure 2 , Figure 3 The pressing mechanism 5 includes a pressing sleeve 501 and a rotating sleeve 502. The pressing sleeve 501 and the rotating sleeve 502 are fixedly connected. The rotating sleeve 502 is threadedly connected to the outer side of the mounting pipe 1. The pressing sleeve 501 abuts against the disc buckle 3. The pressing mechanism 5, which uses a threaded connection, drives the pressing sleeve 501 to move axially by turning the rotating sleeve 502, thereby achieving linear pressing of the disc buckle 3. This mechanical pressing method can generate a uniform and continuous pre-tightening force. At the same time, the threaded drive has a self-locking characteristic, which can effectively prevent loosening caused by construction vibration or load changes, ensuring that the disc buckle maintains a stable connection during long-term use and improving the overall safety performance of the frame.

[0026] See Figure 4 , Figure 5The pressing mechanism 5 also includes a fixed sleeve 503, which is fixedly connected to the mounting tube 1. The inner side of the fixed sleeve 503 has a slot with an opening on one side, and a movable sleeve 504 is movably arranged inside the slot. A manganese steel pressure spring 506 is elastically connected between the upper part of the movable sleeve 504 and the inner side of the slot. The elastic pressing mechanism provides continuous downward pressure to the movable sleeve 504 through the manganese steel pressure spring 506, which can automatically compensate for gap changes caused by wear of parts or temperature changes, and maintain a constant clamping force on the disc buckle 3. At the same time, the adaptive movement of the movable sleeve 504 in the slot allows for a certain degree of deflection tolerance, enabling the structure to adapt to small deformations or installation errors of the pole, thereby enhancing the engineering applicability and seismic performance of the system.

[0027] See Figure 4 , Figure 5 The lower end of the movable sleeve 504 abuts against the disc buckle 3 via a pressure spring 506. A fixing ring 505 is provided on the outer side of the movable sleeve 504. The fixing ring 505 is the point of force application for the operator on the movable sleeve 504. The fixing ring 505 on the outer side of the movable sleeve 504 provides the operator with a clear point of force application, which facilitates height adjustment by tools or manual means, in accordance with ergonomic design principles. At the same time, the elastic support of the manganese steel pressure spring 506 keeps the movable sleeve 504 in contact with the disc buckle 3 at all times, which not only avoids rigid collisions under impact loads, but also ensures the real-time transmission of locking force, improving the convenience and safety of operation.

[0028] See Figure 4 , Figure 5 The upper and lower ends of the installation pipe 1 are both welded and fixed with sleeves 2. The sleeves 2 welded at both ends of the installation pipe 1 form a standardized connection interface, which can be quickly plugged and assembled with poles of different specifications, simplifying the complexity of matching poles on site. At the same time, the thickened design of the sleeves 2 enhances the local stiffness and bending resistance of the connection area, effectively disperses the stress concentration at the node, and improves the load-bearing reliability of the entire pole system under eccentric load conditions.

[0029] See Figure 1 , Figure 2 The outer diameter of the installation pipe 1 is 48mm, and the outer diameter of the sleeve 2 is 60mm. The installation pipe 1 is set with an outer diameter of 48mm and the sleeve 2 with an outer diameter of 60mm. This not only ensures compatibility with commonly used scaffolding uprights, but also achieves a smooth transition in the connection area through the stepped structure. At the same time, the combination of pipes with different diameters optimizes the material distribution, reduces the weight of the components while meeting the strength requirements, and helps to reduce transportation costs and improve the efficiency of on-site handling and assembly.

[0030] The implementation principle of this embodiment is as follows: First, the installation tube 1 is fixed to the external pole through the sleeves 2 at its upper and lower ends. At the same time, the disc buckle 3 is sleeved on the outside of the installation tube 1. By rotating the disc buckle 3, the slot 403 on its surface is aligned with the insertion block 402 of the positioning mechanism 4 welded on the installation tube 1 and inserted, so as to realize the circumferential angle positioning of the disc buckle 3. Finally, by turning the rotating sleeve 502 of the pressing mechanism 5, the pressing sleeve 501 is pushed down to press the disc buckle 3; or by the movable sleeve 504 in the elastic pressing mechanism continuously pressing down under the action of the manganese steel pressure spring 506, the position of the disc buckle 3 is locked in both directions, forming a stable and reliable connection node. The entire process can achieve flexible adjustment and rigid fixation of the disc buckle angle without welding.
