Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a socket-type disc-lock scaffolding. Background Technology
[0002] In construction, bridge building, and municipal engineering, scaffolding serves as a crucial temporary support structure and construction platform, widely used for transporting building materials, erecting worker operating platforms, and supporting complex components. It directly impacts construction efficiency and significantly influences safety during the construction process, making it an indispensable key piece of equipment in various engineering projects.
[0003] In recent years, new types of scaffolding structures have been gradually developed, among which the plug-in disc-lock scaffolding has attracted increasing attention due to its unique structural design and convenient installation method. By setting connecting plates on the uprights and combining them with an efficient locking mechanism, the plug-in disc-lock scaffolding not only improves construction efficiency but also significantly enhances the stability and safety of the scaffolding.
[0004] However, existing socket-type disc-lock scaffolding still has some shortcomings in practical applications. For example, its locking mechanism may loosen after long-term use or after being subjected to external impact, resulting in an unstable connection; some components are prone to falling off during high-frequency disassembly and assembly, affecting safety; in addition, if the components are not aligned accurately or the operation is not standardized during installation, it may complicate the assembly process and reduce construction efficiency. Utility Model Content
[0005] To address the aforementioned problems of unstable scaffolding locking, easy component detachment, and complex installation, this utility model aims to provide a socket-type disc-lock scaffolding. This utility model's device achieves rapid and stable installation and dismantling of scaffolding by optimizing the structural design of the connecting disc and improving the locking method of the locking mechanism.
[0006] The main idea of the technical solution adopted by this utility model is as follows: by setting a connecting plate on the upright and combining it with the locking mechanism at both ends of the horizontal bar and the diagonal tie rod, the radial locking force of the elastic locking rod is used to tightly fit the inner wall of the insertion hole to ensure the firmness of the connection; at the same time, an anti-disengagement structure is set at the end of the elastic locking rod, which further prevents the locking rod from coming out under vibration or external force through the locking block effect; the adjusting handle is set as an elliptical handle that runs through both sides, which is convenient to operate and can be further tied after the elastic locking rod is locked into the connecting plate.
[0007] The technical objective of this utility model is achieved through the following technical solution:
[0008] A type of plug-in disc-lock scaffolding includes uprights, horizontal bars, and diagonal braces. The uprights are characterized by a connecting plate with multiple insertion holes; both ends of the horizontal bars and diagonal braces are equipped with locking mechanisms that connect to the connecting plate via insertion; and the locking mechanisms include a connector and an elastic locking rod, the elastic locking rod passing through both the connector and the insertion holes.
[0009] To achieve the above technical solution, a further preferred solution is as follows: the horizontal bar is connected to the vertical bar in a horizontal direction via a connecting plate, and the diagonal tie rod is connected to the connecting plate on the vertical bar at an inclined angle via a locking mechanism.
[0010] Furthermore, according to the above technical solution, the elastic locking rod includes an adjusting handle and an elastic arm disposed at the lower part of the adjusting handle, and the elastic arm undergoes elastic deformation by the action of the adjusting handle.
[0011] Furthermore, the end of the elastic arm is provided with an anti-detachment hook with a right-angled trapezoidal cross-section.
[0012] Furthermore, the cross-section of the adjusting handle is elliptical, and the wire passes through multiple adjusting handles on a connecting plate to increase the stability of the locking mechanism.
[0013] Furthermore, the connector is provided with a locking hole, and the inner wall of the locking hole is covered with an anti-slip pad.
[0014] By adopting the above technical solution, this utility model has the following technical effects:
[0015] By designing a connecting plate and locking mechanism, horizontal and diagonal braces can be quickly inserted and self-locked, improving installation efficiency and reducing the complexity of manual operation. Simultaneously, the adjusting handle is designed with a hollow elliptical cross-section, serving both as a handle for easy disassembly and as a means of securing it with wire or other connecting elements. This further enhances the overall stability of the scaffolding.
[0016] By incorporating an anti-detachment structure, the radial locking design of the elastic locking rod enhances the strength of the connection, significantly improving the overall stability of the scaffolding. Furthermore, once the elastic locking rod is installed in place, it forms a locking block effect, effectively preventing the locking rod from falling off due to vibration or external forces, further ensuring the safety and durability of the scaffolding in high-rise and complex construction environments.

Detailed Implementation
[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.
[0027] refer to Figure 1-7 This application discloses a plug-in type disc-lock scaffold, including an upright 1, a horizontal bar 2 and a diagonal brace 3. The upright 1 is provided with a connecting plate 4, which has multiple insertion holes 41; both ends of the horizontal bar 2 and the diagonal brace 3 are provided with locking mechanisms 5, which are connected to the connecting plate 4 by plugging.
[0028] like Figure 1 The lower part of the upright 1 is a lead screw, and the height adjustment wrench 11 is set on the top of the lead screw to adjust the overall height of the upright 1. The height adjustment wrench 11 adjusts the height of the connecting plate 4 set on the lead screw by rotating the lead screw part of the upright 1, thereby adapting to different construction height requirements. The height adjustment wrench 11 is designed as a lever structure, which is convenient for workers to operate quickly and improve adjustment efficiency.
[0029] like Figure 2The connecting plate 4 is located on the upper part of the height adjustment wrench 11. The connecting plate 4 is tightly connected to the upright 1 by welding or riveting to ensure that it will not loosen or shift during use. The connecting plate 4 is a flat disc-shaped structure with smooth edges to reduce the risk of scratches to construction personnel during use. The center of the disc is fixed coaxially with the upright 1 to ensure even distribution of force.
[0030] Specifically, the edge of the connecting plate 4 has six insertion holes 41 arranged along the circumferential direction, with each insertion hole 41 evenly distributed at 60° intervals. The distribution design of the insertion holes 41 ensures that the crossbar 2 and the diagonal tie rod 3 can be connected in any direction to form a stable spatial frame structure.
[0031] Specifically, the insertion hole 41 is oblong, adapted to the insertion of the locking mechanism 5. The inner wall of the insertion hole 41 is precision machined to ensure a tight fit with the locking mechanism 5, thereby enhancing the stability of the connection. The insertion hole 41 comes in two sizes, small and large, used for connecting the crossbar 2 and the diagonal tie rod 3, respectively.
[0032] It is worth noting that the six insertion holes 41 of the connecting plate 4 can achieve multi-directional connection, which facilitates flexible adjustment of the position and angle of the horizontal bar 2 and the diagonal brace 3 during construction. The horizontal bar 2 is usually connected horizontally through the small holes of the insertion holes 41 to enhance the lateral stability of the scaffold; the diagonal brace 3 is connected at an angle through the large holes of the insertion holes 41 to increase the shear resistance and lateral support of the overall structure.
[0033] Specifically, the locking mechanism 5 includes a connector 51 and a resilient locking rod 52, which passes through both the connector 51 and the insertion hole 41. The insertion hole 41 cooperates with the resilient locking rod 52 in the locking mechanism 5 to achieve quick installation and disassembly. After insertion, the self-locking function of the resilient locking rod 52 prevents the crossbar 2 and the diagonal tie rod 3 from loosening or falling off during construction.
[0034] like Figure 1 The connector 51 is fixedly mounted at both ends of the crossbar 2 and the diagonal tie rod 3. It is square in shape and has a transverse arc-shaped groove that matches the edge of the connecting plate 4. The connector 51 also has a through locking hole 511 for accommodating the elastic locking rod 52. The inner wall of the locking hole 511 is covered with an anti-slip pad 512, which is made of wear-resistant rubber or high-strength elastic material. This pad enhances the fixing effect of the elastic locking rod 52 and reduces wear.
[0035] like Figure 4The connector 51 is snapped onto the edge of the connecting plate 4. The elastic locking rod 52 passes through the locking hole 511, through the connector 51, and is inserted into the insertion hole 41 of the connecting plate 4 to complete the locking connection with the connecting plate 4. The elastic locking rod 52 includes an adjusting handle 521 and an elastic arm 522 disposed at the lower part of the adjusting handle 521. The elastic arm 522 undergoes elastic deformation under the action of the adjusting handle 521. The upper part of the elastic locking rod 52 is disposed to control the deformation of the elastic arm 522. The adjusting handle 521 is designed as a hollow elliptical structure, and during operation, force is applied to drive the elastic arm 522 to deform.
[0036] Specifically, the elastic arm 522 is located at the lower part of the adjusting handle 521, and has an arc-shaped or bent structure. It is made of high-strength elastic steel. Under the drive of the adjusting handle 521, the elastic arm 522 can undergo elastic deformation, thereby generating a radial locking force in the insertion hole 41 and tightly fitting against the inner wall of the insertion hole 41.
[0037] Specifically, an anti-disengagement hook 523 is provided at the lowest end of the elastic arm 522. The anti-disengagement hook 523 is located at the lowest end of the elastic arm 522 and forms an integrated structure with the elastic arm 522. The cross-section of the anti-disengagement hook 523 is a right trapezoid, and its width is adapted to the inner diameter of the locking hole 511 on the connector 51 and the insertion hole 41 on the connecting plate 4.
[0038] It is worth noting that one side of the anti-disengagement hook 523 is provided with a beveled edge. The angle of the beveled edge is reasonably designed to guide the insertion of the elastic arm 522. The surface of the beveled edge is smoothed to reduce friction with the inner wall of the insertion hole 41 during installation, ensuring smooth installation.
[0039] Specifically, in the right-angled trapezoidal structure of the anti-disengagement hook 523, the wide side is located at the end of the elastic arm 522, forming an outwardly expanding stop. After installation, the wide side of the anti-disengagement hook 523 protrudes through the locking hole 511, and the stop effectively prevents the elastic locking rod 52 from disengaging from the connector 51 and the insertion hole 41 when subjected to a pull-out force.
[0040] During installation, align connector 51 with the insertion hole 41 of connector plate 4, allowing the elastic locking rod 52 to pass through the locking hole 511 and insert into the insertion hole 41. Under external force, adjusting handle 521 applies outward force, causing the elastic arm 522 to expand in an arc shape, fitting against the wall of the insertion hole 41, thus achieving a secure lock. The arc design of the elastic arm 522 allows for the generation of a uniform radial locking force after deformation, effectively preventing loosening.
[0041] Preferably, the cross-section of the adjusting handle 521 is elliptical, which provides greater stability through proper arrangement and coordination when passing through the connecting plate 4. Wires or other connecting elements, such as steel wires or cables, are bound together through multiple adjusting handles 521, enhancing the stability and connection strength between the locking rod 52 and the connecting plate 4. The use of wires or connecting elements not only provides additional support but also effectively resists loosening or failure of the locking structure due to external forces such as wind or gravity. The elliptical design of the adjusting handle 521 facilitates the insertion of wires or connecting elements, allowing for various binding methods to suit different environments and load conditions, thereby enhancing the locking effect.
[0042] Specifically, a sleeve 12 is also provided at the top of the upright 1. The sleeve 12 serves to connect the upper and lower sections of the upright 1. The inner diameter of the sleeve 12 is precisely matched with the outer diameter of the upright 1 to ensure the stability and alignment of the connection. Limiting devices are provided on both sides of the sleeve 12 to prevent the upper and lower upright 1 from misaligning or sliding, thereby enhancing the overall structural strength.
[0043] Specifically, an adjustable support 13 is installed at the top of the top upright 1 of the scaffolding to support the formwork or other construction structures. The support is connected to the upright 1 via a threaded rod, and workers can rotate the support to adjust the extension length of the rod to achieve fine-tuning of the height during construction.
[0044] It is worth noting that the top of the bracket is designed with a U-shaped groove or flat plate structure for fixing the template or other components and ensuring load-bearing stability. The cantilever length of the adjustable bracket 13 extending beyond the top horizontal bar must not exceed 650mm, the exposed length of the threaded rod must not exceed 400mm, and the length of the adjustable bracket inserted into the upright 1 must not be less than 150mm. For safety, the threaded rod of the bracket is designed with a maximum extension limit, usually not exceeding 400mm.
[0045] Specifically, the bottommost upright (1) of the scaffolding is equipped with a fixing seat to secure the scaffolding to the ground. The fixing seat has a flat bottom design with a large contact area to distribute the load and prevent sinking due to insufficient ground bearing capacity. The fixing seat can be fixed to the ground with expansion bolts to enhance the overall stability of the scaffolding. The fixing seat is also designed with drainage holes to remove accumulated water and prevent the foundation from getting damp, which could affect the stability of the scaffolding.
[0046] Specifically, the bottom support pole 1 is directly inserted into the socket of the fixing base through its bottom, and the socket of the fixing base fits tightly with the outer diameter of the support pole 1. The four corners of the fixing base are designed with reinforcement holes, which can be used to fix it to the ground with bolts or steel nails to ensure its stable position.
[0047] The workflow of this embodiment is as follows:
[0048] Pre-install locking mechanisms 5 at both ends of the horizontal bar 2 and the diagonal brace 3 to ensure that the connecting piece 51 and the elastic locking rod 52 are properly assembled and that the anti-disengagement hook 523 is in its initial undeformed state. After laying out the dimensions according to the scaffolding configuration drawing, arrange the adjusting seats to the fixed points, and insert the upper part of the sleeve 12 of the base upright 1 into the upper part of the adjusting seat with the upper part facing upward. The lower edge of the base must be completely placed into the groove of the wrench bearing plane.
[0049] Position the upright 1 to the designated location and install the connecting plate 4. Align the locking mechanism 5 of the horizontal bar 2 or the diagonal tie rod 3 with the insertion hole 41 on the connecting plate 4. Operate the adjusting handle 521 to cause the elastic arm 522 to retract inward, facilitating the smooth insertion of the anti-disengagement hook 523 into the insertion hole 41.
[0050] After the insertion end of the crossbar 2 or the diagonal tie rod 3 is fully inserted into the insertion hole 41, the adjusting handle 521 is released, causing the elastic arm 522 to expand outward under the elastic recovery action. The elastic arm 522 fits against the hole wall of the insertion hole 41, while the anti-disengagement hook 523 extends out of the insertion hole 41 and the locking hole 511 after expansion, completing the locking.
[0051] Based on the overall structural requirements of the scaffolding, repeat the insertion and connection process to install the remaining horizontal bars 2, diagonal braces 3, and vertical bars 1, ensuring that all components are properly inserted and locked. Adjust the height adjustment wrench 11 or the adjustable bracket 13 to fine-tune the height and level of the overall structure.
[0052] Check that all locking mechanisms 5 are fully locked, ensure that the elastic arms 522 are all aligned with the insertion holes 41, and that the anti-disengagement hooks 523 are correctly engaged on the outside of the locking holes. Ensure that the entire scaffolding structure is stable and reliable, and meets construction safety requirements.
[0053] Depending on the actual situation, iron wire or other connecting elements such as steel wire or cable can be used through multiple adjusting handles 521 to further bind the locking mechanism 5 to the connecting plate 4, or to further bind the locking mechanism 5 to the column 1, thereby enhancing the stability of the scaffold structure.
