Description

Technical Field

[0001] This utility model relates to the field of disc-lock scaffolding, specifically a platform plate locking structure for disc-lock scaffolding. Background Technology

[0002] Disc-lock scaffolding is a new type of building support system. Its core feature is the welding of perforated connecting discs to the uprights, which quickly fix horizontal and diagonal bars through pin connections. This design gives it structural stability and high load-bearing capacity. The load-bearing capacity of a single upright is much higher than that of traditional scaffolding. At the same time, its modular design significantly improves the efficiency of assembly and disassembly, saving time.

[0003] Currently, disc-lock scaffolding has the advantages of high erection efficiency and strong stability. However, there is a problem in the actual erection process. Specifically, the load-bearing connection structure of the steel strips used for erection is only the hooks on both sides and the interlocking structure with the pipe frame. This results in poor load-bearing capacity in the middle of the steel strip and easy bending and deformation. In view of this, the inventor urgently needs to design a stable locking mechanism for steel planks to improve the stability of scaffolding. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a locking structure for platform boards in disc-lock scaffolding to solve the technical problem of easy bending of the steel plank under load in the middle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a platform plate locking structure for disc-lock scaffolding, including a horizontal bar and steel planks. The horizontal bar is a connecting support rod for the scaffolding pipe frame. Clips are welded and fixed to both sides of the horizontal bar. An mounting plate is provided on the upper side of the horizontal bar. A pin is fixedly provided on one side of the mounting plate, and a pin is hinged to the other side of the mounting plate via a hinge plate. Two sets of through slots are provided on the horizontal bar. Two sets of limiting hooks are fixedly provided on the surface of the mounting plate at positions opposite to the through slots. The limiting hooks penetrate the through slots and engage with the horizontal bar to fix the position of the mounting plate. Cards are fixedly installed on both sides of the steel scaffolding. The cards are locked between the mounting plate and the horizontal bar to lock and support the two sides of the steel scaffolding where no hooks are installed.

[0006] By adopting the above technical solution, the clips on both sides of the steel scaffold can be stably locked between the mounting plate and the horizontal bar, thus providing a strong rigid support point for the middle of the steel scaffold. This changes the traditional load-bearing mode of steel scaffolds, which rely solely on the hooks at both ends for load-bearing and are suspended in the middle. The load in the middle of the scaffold is effectively transferred to the horizontal bar, which is the main load-bearing component, through the clips and the mounting plate. This significantly improves the overall rigidity and bending resistance of the steel scaffold, and greatly enhances the safety and stability of the work platform.

[0007] Furthermore, both ends of the horizontal bar are connected to the external pipe rack via snap-fit ​​connectors, pins, and disc buckles.

[0008] By adopting the above technical solution, the horizontal bar itself becomes a standard disc-lock scaffolding component with complete connection function. At the same time, it ensures the system compatibility and overall stability of the entire structure. Since the horizontal bar adopts the same end connection method as the conventional disc-lock scaffolding horizontal bar, it can be seamlessly integrated into any standard disc-lock scaffolding system without causing connection conflicts or requiring special adapter parts.

[0009] Furthermore, the connector has an overall "U" shaped structure, and a pin hole is provided on the connector for the insertion pin to pass through.

[0010] By adopting the above technical solution, the clamp connector is defined as an overall "U" shaped structure. The "U" shaped structure can wrap around the connecting plate on the pole from three directions like a clamp, providing a stable and centered channel for subsequent insertion of the pin. This structure allows workers to easily clamp the clamp connector onto the connecting plate during installation, and it can be easily operated even with one hand, greatly improving the construction efficiency.

[0011] Furthermore, the limiting hook has an overall "L" shaped structure, and the limiting hook passes through the through groove and engages with the horizontal rod.

[0012] By adopting the above technical solution, the short side of the "L" shape can easily pass through the through groove, and then by rotating or translating the mounting plate, the long side of the "L" shape can be hooked onto the inner wall of the horizontal bar. This snap-fit ​​method is extremely simple to operate, and workers can master it after simple training. It can achieve initial fixation, greatly improve installation efficiency, and meet the efficiency requirements of scaffolding construction.

[0013] Furthermore, the pin has a wedge-shaped structure.

[0014] By adopting the above technical solution, this friction can effectively resist the dynamic load generated by personnel movement and equipment vibration during the use of scaffolding, prevent the pins from gradually loosening or even falling off due to vibration, and fundamentally eliminate the major safety hazard of connection node failure.

[0015] Furthermore, the mounting plate, pin, and limit hook are all made of Q235B carbon structural steel.

[0016] By adopting the above technical solution, Q235B steel is a commonly used engineering steel with a good combination of strength, plasticity and toughness. Its yield strength is 235MPa, which can provide sufficient load-bearing capacity for the locking mechanism to withstand the construction load transmitted from the steel scaffolding and prevent plastic deformation or fracture due to insufficient strength.

[0017] In summary, the present invention has the following main advantages: This utility model provides a solid rigid support point for the card in the middle of the steel scaffold by engaging the mounting plate, the limiting hook, and the through groove on the horizontal bar. This changes the load transmission path, allowing the load in the middle of the steel scaffold to be directly transmitted to the horizontal bar through the card and the mounting plate. This significantly enhances the overall rigidity and bending resistance of the steel scaffold, and greatly improves the safety and load-bearing stability of the work platform.

[0020] 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.

[0021] In this embodiment: A type of disc-lock scaffolding uses a platform plate locking structure, such as Figure 1-3 As shown, it includes a horizontal bar 1 and a steel plank 8. The horizontal bar 1 is a connecting support rod for the scaffolding pipe frame. Both sides of the horizontal bar 1 are welded and fixed with clamping joints 2. An installation plate 4 is provided on the upper side of the horizontal bar 1. A pin 6 is fixedly provided on one side of the installation plate 4. The other side of the installation plate 4 is hinged with a pin 6 through a hinge plate 5. Two sets of through grooves 7 are opened on the horizontal bar 1. Two sets of limiting hooks 3 are fixedly provided on the surface of the installation plate 4 and at the position opposite to the through grooves 7. The limiting hooks 3 pass through the through grooves 7 and engage with the horizontal bar 1 to fix the position of the installation plate 4. Cards 9 are fixedly installed on both sides of the steel scaffolding 8. The cards 9 are locked between the mounting plate 4 and the horizontal bar 1 to lock and support the two sides of the steel scaffolding 8 where no hooks are installed.

[0022] This allows the clips 9 on both sides of the steel scaffold plank 8 to be stably secured between the mounting plate 4 and the horizontal bar 1, providing a strong rigid support point for the middle of the steel scaffold plank 8. This changes the traditional load-bearing mode of steel scaffold planks, which rely solely on the hooks at both ends for load-bearing and are suspended in the middle. The load in the middle of the plank is effectively transferred to the horizontal bar 1, which is the main load-bearing component, through the clips 9 and the mounting plate 4. This significantly improves the overall rigidity and bending resistance of the steel scaffold plank 8, greatly enhancing the safety and stability of the work platform. At the same time, the mounting plate 4, as an independent component, can be quickly assembled and disassembled with the standard horizontal bar 1 and the steel scaffold plank 8 without requiring large-scale modifications to the existing scaffolding pipe frame system. It is highly versatile and has a low cost. The clip joints 2 welded to both ends of the horizontal bar 1 and the pins 6 set on the mounting plate 4 ensure that the horizontal bar 1 unit can be quickly connected to the scaffolding uprights through the disc-lock joint, maintaining the inherent advantage of high efficiency in the erection and dismantling of disc-lock scaffolding.

[0023] See Figure 1 , Figure 2 , Figure 3 Both ends of the horizontal bar 1 are connected to the external pipe frame via clamp connectors 2, pins 6, and disc buckles, making the horizontal bar 1 itself a standard disc buckle scaffolding component with complete connection function. At the same time, it ensures the system compatibility and overall stability of the entire structure. Since the horizontal bar 1 adopts the same end connection method as the conventional disc buckle scaffolding horizontal bar, it can be seamlessly integrated into any standard disc buckle scaffolding system without causing connection conflicts or requiring special adapter parts. This not only reduces manufacturing and use costs, but also makes this enhanced locking structure flexibly applicable to various existing scaffolding projects, greatly enhancing its potential for widespread application.

[0024] See Figure 1 , Figure 2 , Figure 3 The clamp connector 2 has an overall "U" shape. The clamp connector 2 has a pin hole for the pin 6 to pass through, which limits the clamp connector 2 to an overall "U" shape. The "U" shape can wrap around the connecting plate on the pole from three directions like a clamp, providing a stable and centered channel for the subsequent insertion of the pin 6. This structure allows workers to easily clamp the clamp connector 2 onto the connecting plate during installation, and it is easy to operate even with one hand, which greatly improves the efficiency of the construction. At the same time, the pin hole for the pin 6 to pass through on the clamp connector 2 is the key to achieving quick locking and reliable force transmission. The cooperation between the pin hole and the wedge-shaped pin 6 forms a hinged joint with extremely strong tensile and shear resistance.

[0025] See Figure 1 , Figure 2 , Figure 3The limiting hook 3 has an overall "L" shape structure. The limiting hook 3 passes through the through groove 7 and engages with the horizontal bar 1. The short side of the "L" shape can easily pass through the through groove 7, and then by rotating or translating the mounting plate 4, the long side of the "L" shape hooks onto the inner wall of the horizontal bar 1. This engaging method is extremely simple to operate and can be mastered by workers after simple training. It can achieve initial fixation and greatly improve installation efficiency, which meets the pursuit of efficiency in scaffolding construction. At the same time, the "L" shape structure provides excellent tensile and overturning resistance. When the card 9 of the steel scaffolding 8 is inserted and pressed, the long side of the "L" shaped limiting hook 3 will firmly abut against the inner wall of the horizontal bar 1, forming an effective lever balance and preventing the mounting plate 4 from being tilted or detached. This mechanical interlocking method is very reliable. Its strength depends on the strength of the steel itself and is not easy to age or fail, ensuring the long-term stability of the locking structure under long-term use and dynamic loads.

[0026] See Figure 1 , Figure 2 , Figure 3 The pin 6 has a wedge-shaped structure. This friction can effectively resist the dynamic loads generated by personnel movement and equipment vibration during the use of the scaffold, preventing the pin 6 from gradually loosening or even falling off due to vibration. This fundamentally eliminates the major safety hazard of connection failure. At the same time, the wedge-shaped structure also brings the dual benefits of convenient installation and tight connection. In the initial stage of installation, the thinner end of the pin 6 is easy to align with the pin hole, reducing the installation difficulty. With hammering, the pin 6 becomes tighter and tighter, which can automatically eliminate the gaps caused by manufacturing tolerances or wear, so that the node connection reaches a tight state, significantly improving the overall rigidity and stability of the scaffold.

[0027] See Figure 1 , Figure 2 , Figure 3 Mounting plate 4, pin 6, and limit hook 3 are all made of Q235B carbon structural steel. Q235B steel is a commonly used engineering steel with a good balance of strength, plasticity, and toughness. Its yield strength is 235MPa, which can provide sufficient load-bearing capacity for the locking mechanism to withstand the construction load transmitted from the steel scaffold 8 and prevent plastic deformation or fracture due to insufficient strength. At the same time, it has excellent weldability, which allows the limit hook 3 to be welded and fixed to the surface of the mounting plate 4 with high quality, forming a solid whole. Q235B steel is widely available and relatively inexpensive, which helps to control the manufacturing cost of the locking structure and promote its large-scale production and application.

[0028] The implementation principle of this embodiment is as follows: by using an installation plate 4 structure that can be quickly installed on the horizontal bar 1 of the scaffold, effective rigid support is provided for the middle part of the steel plank 8, thereby solving the problem of insufficient load-bearing capacity due to the middle part being suspended.

[0029] Specifically, firstly, the limiting hook 3 on one side of the mounting plate 4 is passed through the corresponding through slot 7 on the horizontal bar 1, so that the limiting hook 3 engages with one side of the horizontal bar 1, thereby initially fixing the mounting plate 4. Simultaneously, the pre-installed clips 9 on both sides of the steel scaffold plank 8 are inserted and secured in the gap between the fixed mounting plate 4 and the horizontal bar 1. This operation allows the central load of the steel scaffold plank 8 to be directly transferred to the horizontal bar 1, which is the main load-bearing component, through the clips 9 and the mounting plate 4, greatly enhancing the bending resistance of the central part of the steel scaffold plank 8. At the same time, the locking joints 2 at both ends of the horizontal bar 1 are locked to the connecting discs on the scaffold uprights via pins 6, ensuring the stability of the entire support system.
