Description

Technical Field

[0001] This application relates to the field of scaffolding technology in construction engineering, specifically to a new type of quick-assembly scaffolding stabilization device. Background Technology

[0002] In the field of construction, especially for small buildings such as villas and for partial maintenance work, traditional large scaffolding systems are too cumbersome and complicated to install. Such scenarios usually require a support structure that can be quickly erected and provides sufficient stability.

[0003] The stability of traditional scaffolding largely depends on the overall frame stability system formed by the interconnection of diagonal, horizontal, and vertical members. However, in localized maintenance or small-scale projects, space constraints make it difficult to create large, self-locking structures, which greatly limits the application of this overall frame stability system.

[0004] Therefore, it is particularly important to design a quick-install scaffolding stabilization device specifically suitable for local maintenance work. Summary of the Invention

[0005] In response to the aforementioned needs, this application proposes a novel quick-assembly scaffolding stabilization device, which aims to enhance vertical stability by simplifying the connection method, enabling the entire scaffolding to maintain sufficient rigidity and stability during local maintenance and small-scale construction applications.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] A novel quick-install scaffolding stabilizing device includes a connecting rod that can be fitted onto a scaffolding upright and a connecting plate disposed between the two ends of the connecting rod, wherein the connecting plate is provided with a plurality of joint holes arranged in a ring.

[0008] The lower end of the connecting plate is provided with a first flange that can fit over the upright. The first flange is provided with a first flange plate that fits against the connecting plate and a first sleeve extending downward from the inner ring of the first flange plate. The first flange plate is provided with a mounting hole that is coaxially aligned with the joint hole.

[0009] In this way, the connecting rod is clamped on both the inner and outer sides by the first flange and the connecting rod, increasing the rigidity of the end of the upright and enabling it to withstand axial pressure. Simultaneously, the joint hole of the connecting plate and the mounting hole of the first flange are coaxially aligned, allowing the fastener to pass through simultaneously, increasing connection rigidity. At this point, the installation of the horizontal bar causes localized stress on the entire connecting plate, generating bending force on the connecting rod. The connecting rod and the first flange then conversely restrict the upright, thus preventing the connecting plate from rotating relative to the upright.

[0010] In some possible implementations, the connecting disc and the first flange have the same diameter.

[0011] In some possible implementations, a second flange is also provided at the upper end of the connecting plate, the second flange including a second flange plate that fits against the connecting plate and a second sleeve extending upward from the inner ring of the second flange plate.

[0012] In some possible implementations, the second flange is positioned within the inner ring of the annularly arranged plurality of connector holes.

[0013] In some possible implementations, the upper connecting rod at the top of the connecting plate and the lower connecting rod at the bottom of the connecting plate are of the same length.

[0014] In some possible implementations, the length H1 of the lower connecting rod is greater than or equal to the length H2 of the first sleeve.

[0015] In some possible implementations, the length H2 of the first sleeve is always ≥ 1.5 times the diameter D of the upright.

[0016] In some possible implementations, the first gap between the first flange and the upright is smaller than the second gap between the upright and the connecting rod. Attached Figure Description

[0022] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0023] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0025] During localized maintenance work, the workload is generally small, requiring rapid assembly and disassembly of scaffolding. However, compared to traditional large-area scaffolding, the localized areas are smaller, making it difficult to form a rigid overall structure. Therefore, the rigid connections of individual scaffolding pieces are particularly important.

[0026] Please refer to the following for details. Figure 1 , Figure 2 and Figure 4 The novel quick-installation scaffolding stabilizing device of this application includes a connecting rod 2 that can be fitted onto the uprights 1 of the scaffolding, and a connecting plate 3 is provided between the two ends of the connecting rod 2. In order to improve the installation error tolerance, it is preferable that the upper connecting rod 21 at the upper end of the connecting plate 3 and the lower connecting rod 22 at the lower end of the connecting plate 3 are of the same length.

[0027] The upright 1 can be made of conventional Φ48.3×3.6 mm steel pipe, while the connecting rod 2 can be simply fitted inside. At this point, with the connecting plate 3 as the dividing line, the connection mechanism of the scaffold upright 1 is formed relative to the upper and lower ends of the upright 1. The connecting plate 3 is provided with multiple joint holes 31 in a ring. The joint holes 31 are through holes through which the fasteners (marked in the figure) pass and are fixed when the scaffold is connected by couplers. This is a common technical means in the industry and will not be described in detail.

[0028] At this point, the two steel pipes are actually connected, especially at the bottom of the connecting plate 3. After the horizontal bar is installed through the coupling, the increased axial pressure may cause the interface of the lower vertical pole 1 to collapse. At the same time, it may also cause the connecting rod 2 to rotate relative to the vertical pole 1 and deviate.

[0029] To address this, this application provides a first flange 4 at the lower end of the connecting plate 3, which can accommodate the upright 1. The first flange 4 has a first flange plate 41 that fits against the bottom of the connecting plate 3 from bottom to top, and a first sleeve 42 extending downward from the inner ring of the first flange plate 41, which accommodates the upright 1. The first flange plate 41 has a mounting hole 43 coaxially aligned with the connector hole 31. This coaxial alignment means that when the fastener passes through, it can pass through both the connector hole 31 and the mounting hole 43 simultaneously. Therefore, it is preferable that the connecting plate 3 and the first flange plate 41 have the same diameter.

[0030] Please refer to the reference. Figure 5To ensure a sufficiently long insertion depth (also known as overlap length) to guarantee that the connection can withstand the expected load without failure, it is preferable that the length H1 of the lower connecting rod 22 is greater than or equal to the length H2 of the first sleeve 42. The length H2 of the first sleeve 42 is greater than or equal to 1.5 times the diameter D of the upright 1. If actual working conditions permit, the overlap length can be appropriately increased. For example, for an upright 1 with a diameter of Φ48.3 mm, the length of the first sleeve 42 should be at least 72.5 mm, and if conditions allow, it can be up to 100 mm.

[0031] Thus, by clamping the connecting rod 2 on both the inner and outer sides through the first flange 4, the rigidity of the end of the upright 1 is increased, enabling it to withstand axial pressure. Simultaneously, the joint hole 31 of the connecting plate 3 and the mounting hole 43 of the first flange 41 are coaxially aligned, allowing the fastener to pass through simultaneously, increasing connection rigidity. At this point, the installation of the horizontal bar causes localized stress on the entire connecting plate 3, generating bending force on the connecting rod 2. The connecting rod 2 and the first flange 4 then conversely restrict the upright 1, thereby preventing the connecting plate 3 from rotating relative to the upright 1.

[0032] Please combine Figure 3 As described above, the connecting rod 2 generates a bending force, which is used to limit the rotation of the upright 1 relative to the connecting plate 3. Preferably, the first gap 100 between the first flange 4 and the upright 1 is smaller than the second gap 200 between the upright 1 and the connecting rod 2.

[0033] Specifically, the gap between the first flange 4 and the scaffold upright 1 should be kept as small as possible (not exceeding 1 mm) to ensure a tight fit between the first flange 4 and the upright 1 and reduce the risk of shaking or rotation caused by loosening.

[0034] The portion of the pole 1 into which the connecting rod 2 is inserted allows for a slightly larger gap (between 1 and 3 mm) to facilitate quick on-site installation and disassembly, and also overcomes the defect that the port of the pole 1 is relatively easy to deform.

[0035] Please refer to the reference. Figure 1 and Figure 4 In some embodiments, when the scaffolding is high, the lower end of the upright 1, that is, the port of the upright 1 at the upper end of the connecting plate 3, may also be prone to deformation. To address this, a second flange 5 is provided at the upper end of the connecting plate 4. The second flange 5 includes a second flange 51 that fits against the connecting plate 4 and a second sleeve 52 extending upward from the inner ring of the second flange 51. The second flange 51 is placed within the inner ring of the plurality of annularly arranged joint holes 31. That is, the second flange 51 is placed within the inner ring of the connecting plate 3 and does not cover the joint holes 31, thus not affecting the installation of the fasteners.

[0036] As stated above, this case protects a novel quick-assembly scaffolding stabilization device, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
