Description

Technical Field

[0001] This application relates to the field of building scaffolding technology, and in particular to a scaffolding connection structure. Background Technology

[0002] Currently, construction scaffolding serves as an indispensable temporary support structure on construction sites, providing safety for workers during high-altitude operations. With the expansion of construction projects and the increasing complexity of construction environments, the design and installation of scaffolding face increasingly higher requirements. The connection structure of scaffolding not only needs to ensure the overall stability of the structure but also requires high flexibility and ease of assembly and disassembly.

[0003] To address these needs, existing construction scaffolding connection structures are typically spliced ​​together using various connectors. During installation, the tightness of each connection component is ensured by adjusting the fastening bolts. Meanwhile, some structures employ adjustable connection methods to accommodate changes in height and construction requirements.

[0004] However, in existing technologies, the fixing methods for scaffold connection structures usually rely on a single fastening method, such as the combination of bolts and clamping plates. This not only requires a lot of manual operation, increasing construction time and complexity, but also lacks sufficient flexibility. During installation, problems such as loose connecting parts and uneven stress are also faced, especially the stress at the connection points is prone to concentration, which leads to insufficient load-bearing capacity of the structure.

[0029] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0031] The scaffolding connection structure will be described in detail below through specific embodiments:

[0032] Reference Figures 1 to 3 As shown, some embodiments of this application provide a scaffolding connection structure for connecting a first frame and a second frame. The scaffolding connection structure includes a first cylinder 1, a second cylinder 4, a clamping assembly, and a pressure-distributing assembly 5.

[0033] The clamping assembly includes a first clamping member 2 and a second clamping member 3. The first clamping member 2 has a first connecting end and a first movable end, and the second clamping member 3 has a second connecting end and a second movable end. The first connecting end and the second connecting end are rotatably connected, and the first movable end and the second movable end are detachably connected. After the first movable end and the second movable end are connected, the first clamping member 2 and the second clamping member 3 surround the outside of the first cylinder 1. That is, the first clamping member 2 and the second clamping member 3 can surround the first cylinder 1 through the rotatably connected first connecting end and second connecting end, and when the first movable end and the second movable end are connected, the first clamping member 2 and the second clamping member 3 can be fixed to the outside of the first cylinder 1.

[0034] At least one of the first clamping member 2 and the second clamping member 3 is provided with a second cylinder 4. The axial direction of the second cylinder 4 intersects the axial extension direction of the first cylinder 1. In use, the first frame is installed inside the first cylinder 1 and the second frame is installed inside the second cylinder 4. Thus, when the clamping assembly is fixed on the first cylinder 1, the second cylinder 4 can be fixed in position relative to the first cylinder 1, thereby realizing the connection between the first frame and the second frame.

[0035] One end of the pressure-distributing component 5 is connected to the first cylinder 1, and the other end is connected to the second cylinder 4. That is, the pressure-distributing component 5 can evenly distribute the connection load between the first cylinder 1 and the second cylinder 4, improve the load-bearing capacity of the connection point, reduce the risk of deformation or loosening of the connection part during the scaffolding erection process, thereby improving the overall stability and safety of the scaffolding, reducing the complexity of manual operation, and improving installation efficiency.

[0036] It should be noted that for traditional scaffolding connectors, disassembly may require completely unscrewing and removing multiple bolts to loosen the fasteners. This process is not only cumbersome, but also causes the horizontal bars to instantly lose all support, requiring workers to continuously lift them, posing a safety risk. After adjustment, the holes must be re-aligned, bolts inserted, and tightened one by one. In other words, a "complete disassembly" is required to achieve temporary adjustments.

[0037] In this application, when the height of the horizontal bar (i.e., the second frame) needs to be adjusted, the operator does not need to completely disassemble the first clamping member 2 and the second clamping member 3. They only need to reduce the clamping force of the first clamping member 2 and the second clamping member 3 on the vertical cylinder (i.e., the first frame). At this time, the entire clamping assembly, together with the second cylinder 4 and the second frame, can slide up and down along the first cylinder 1, and the temporary adjustment of the scaffolding can be completed without complete disassembly.

[0038] Specifically, the connection between the first frame and the first cylinder 1, and the connection between the second frame and the second cylinder 4, can be achieved by pre-drilling through holes in the cylinder walls of the first cylinder 1 and the second cylinder 4. After the first frame is inserted into the first cylinder 1 or the second frame is inserted into the second cylinder 4, a through-hole locking pin or high-strength bolt is used to pass through the frame and the cylinder wall, and then a nut or pin is used to lock them in place. Alternatively, a set screw (i.e., a set screw) can be installed on the cylinder wall, and the internal frame can be pressed together by tightening the set screw to achieve friction fixation.

[0039] In some embodiments, the pressure-dividing assembly 5 includes a rotating disk 51, a fixing block 52, and a connecting rod 53. The rotating disk 51 is sleeved on the outside of the first cylinder 1, the fixing block 52 is disposed on the second cylinder 4, and one end of the connecting rod 53 is rotatably connected to the rotating disk 51 along the circumferential direction of the first cylinder 1, while the other end is rotatably connected to the fixing block 52. That is, when the first clamping member 2 and the second clamping member 3 rotate relative to each other, the rotating disk 51 can avoid the connecting rod 53 connected to the second cylinder 4, so that the connecting rod 53 and the rotating disk 51 can move relative to each other.

[0040] Reference Figure 1 As shown, a groove 511 is provided on the rotating disk 51, which extends along the circumferential direction of the first cylinder 1. One end of the connecting rod 53 forms a first spherical part 531, which is slidably disposed in the groove 511 and rotates in cooperation with the groove 511. That is, the first spherical part 531 rotates in the groove 511 to adapt to changes in angle. A spherical groove is provided on the fixing block 52, and a second spherical part 532 is formed on the other end of the connecting rod 53. The second spherical part 532 is rotatably disposed in the spherical groove. That is, the second spherical part 532 rotates in the spherical groove to adapt to changes in angle.

[0041] In practice, one end of the connecting rod 53, namely the first spherical part 531, can move relative to the first rod body 533, and the other end, namely the second spherical part 532, can move relative to the second rod body 534. In this way, it can more flexibly adapt to different angles and spatial requirements and improve the stability of the connection between the first frame and the second frame.

[0042] In some embodiments, the connecting rod 53 includes a first rod body 533 and a second rod body 534 rotatably connected. The end of the first rod body 533 away from the second rod body 534 is formed as a first spherical portion 531, and the end of the second rod body 534 away from the first rod body 533 is formed as a second spherical portion 532. It is understood that an additional movable node is formed between the first rod body 533 and the second rod body 534. When the second frame and the first frame are relatively tilted, the connecting rod 53 can adaptively bend, ensuring that the first spherical portion 531 always conforms to the sliding groove 511 and that the second spherical portion 532 always conforms to the spherical groove. This configuration enhances the angular adaptability between the first and second frames, making it suitable for complex scaffolding structures.

[0043] In some embodiments, refer to Figure 2 and Figure 3As shown, the scaffolding connection structure also includes a pressure assembly 6, which includes a first plate 61, a second plate 62, and an elastic element 63 elastically disposed between the first plate 61 and the second plate 62. The first plate 61 is disposed on the first clamping member 2, and the second plate 62 is disposed on the second clamping member 3. In specific implementation, the first plate 61 is fixed to the outer wall of the first clamping member 2, and the second plate 62 is fixed to the outer wall of the second clamping member 3. When the clamping assembly is closed, the gap between the first plate 61 and the second plate 62 compresses the elastic element 63 to generate a pre-tightening force. When vibration causes the clamping assembly to loosen slightly, the elastic element 63 pushes the first plate 61 and the second plate 62 back to their original positions to maintain the clamping force on the clamping assembly. This can dynamically compensate for the loss of pre-tightening force of the elastic element 63 and prevent the risk of loosening during high-altitude operations.

[0044] It is worth mentioning that when the scaffolding connection structure is adjusted in real time, the elastic element 63 in the pressure assembly 6 will still provide a certain pre-tightening force when the first movable end and the second movable end are disassembled, to prevent the clamping assembly from accidentally opening and falling off. After the clamping assembly is adjusted to the new position, it is only necessary to reconnect the first movable end and the second movable end to complete the fixation. It does not require complete disassembly, which greatly simplifies the operation steps, improves the adjustment efficiency and construction safety, and the advantages are more obvious, especially when a single person is working at height.

[0045] Continue to refer to Figure 2 and Figure 3 As shown, the pressurizing assembly 6 also includes a guide rod 64. A first guide hole is provided on the first plate 61 and a second guide hole is provided on the second plate 62. The guide rod 64 passes through the first guide hole and the second guide hole in sequence, so as to guide the first plate 61 and the second plate 62 to move closer to each other, which can prevent the elastic element 63 from bending laterally and improve the pressurization stability.

[0046] Specifically, the guide rod 64 is formed as an arc-shaped rod, with the center of the arc coaxial with the axis of the first cylinder 1. It can be understood that when the clamping assembly opens and closes, the guide rod 64 guides the first clamping member 2 and the second clamping member 3 to move closer or further apart, avoiding motion interference and extending the assembly's lifespan.

[0047] Furthermore, both ends of the guide rod 64 are formed as limiting ends, and the cross-sectional area of ​​the limiting ends is larger than the cross-sectional area of ​​the guide rod 64, so as to prevent the guide rod 64 from detaching from the first plate 61 or the second plate 62 and ensure structural stability.

[0048] In some embodiments, the clamping assembly further includes a rotating shaft 7, with a first through hole on the first connecting end and a second through hole on the second connecting end, through which the rotating shaft 7 passes. That is, the rotating shaft 7 can pass through the first connecting end and the second connecting end in sequence, so that the rotating shaft 7 can serve as the axis for the relative rotation of the first clamping member 2 and the second clamping member 3, thereby realizing the installation and removal of the clamping assembly on the outside of the first cylinder 1.

[0049] Furthermore, a first limiting block 71 and a second limiting block 72 are respectively provided at both ends of the rotating shaft 7, and the cross-sectional area of ​​the first limiting block 71 and the second limiting block 72 is larger than the cross-sectional area of ​​the rotating shaft 7, so as to prevent the rotating shaft 7 from coming off the first connecting end or the second connecting end and to ensure structural stability.

[0050] In some embodiments, the scaffolding connection structure further includes a connector 8. The first clamping member 2 has a first connecting hole, and the second clamping member 3 has a second connecting hole. The connector 8 is sequentially inserted into the first connecting hole and the second connecting hole to connect the first movable end and the second movable end.

[0051] In a specific implementation, the connector 8 is a fastener such as a screw or bolt. At least one of the first connecting hole and the second connecting hole is formed as a threaded hole. After the fastener passes through the other of the first connecting hole and the second connecting hole, it is threaded into the threaded hole, which can realize the connection between the first clamping member 2 and the second clamping member 3, and can also facilitate disassembly and position adjustment.

[0052] In some embodiments, the scaffolding connection structure further includes a support 9, and the first cylinder 1 is disposed on the support 9. That is, when the scaffolding connection structure of this application is used as a foundation connection, by setting the support 9, the scaffolding can be fixed to the ground or the main building. Specifically, the support 9 can be firmly anchored to the foundation by fasteners such as fixing bolts 91, which can ensure the overall stability of the scaffolding.

[0053] Of course, the scaffolding connection structure can also be used as an intermediate connection. Through the first cylinder 1, the second cylinder 4, the clamping assembly, and the pressure-distributing assembly 5, the first and second frames of the scaffolding can be connected at the middle position. In this application scenario, the first cylinder 1 itself acts as a sleeve, fitted onto the first frame of a continuous, through-type scaffold. The clamping assembly will directly clamp the first cylinder 1 at any required height, and then connect to the second frame. It has high versatility, serving as both a "starting connector" with bracket 9 and an "intermediate cross joint" without bracket 9, meeting the needs of different construction locations.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0055] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
