Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a fastening component for scaffolding. Background Technology

[0002] Scaffolding is a temporary support platform and safety protection facility used in construction for worker operations, material storage, and short-distance transportation. It is typically assembled from components such as steel pipes and frames. Fasteners are the key parts that firmly connect these components together. The most common are scaffold couplers; for example, right-angle couplers are used to connect two perpendicularly intersecting steel pipes, swivel couplers are used to connect intersecting steel pipes at any angle, and butt couplers are used to extend steel pipes. These fasteners generate friction through bolt tightening, ensuring the stability and reliability of the entire scaffolding structure, and are an indispensable part of the support system.

[0003] Existing scaffolding fastening components have significant defects in practical applications. Their connections often rely on welding, resulting in concentrated locking force and insufficient reliability. Under long-term dynamic loads and vibrations, they are prone to loosening, posing safety hazards. Furthermore, traditional connection methods are often rigid, lacking effective adjustment capabilities. They impose strict limitations on the diameter or installation angle of connecting members, exhibiting poor adaptability. On-site installation often requires laborious adjustments using additional tools or even on-site cutting, leading to low installation efficiency and difficulty in ensuring that the connection nodes consistently achieve the designed tight fit and uniform stress distribution. Utility Model Content

[0004] The purpose of this utility model is to provide a fastening component for scaffolding, which solves the problem that existing scaffolding connection nodes mostly rely on welding, resulting in concentrated locking force and insufficient reliability. Under long-term dynamic loads and vibrations, they are prone to loosening, posing safety hazards.

[0005] To achieve the above objectives, a fastening component for scaffolding is provided, including a top plate, with columns installed at four ends below the top plate, and connectors installed on the four columns. The connectors are fitted with positioning bolts three to the internal threads of the columns. An installation component one is fixedly connected to the top of the connectors, and an installation component two is fixedly connected to the lower end of the connectors. One end of each of the mounting components is fixedly connected to a mounting block. The mounting block has an internal mounting groove, and a positioning block is correspondingly provided inside the mounting groove. The other end of the positioning block is fixedly connected to a fixing ring.

[0006] According to the fastening component of the scaffold, the mounting block and the positioning block are internally threaded with positioning bolts two, and the opening end of the fixing ring is threaded with positioning bolt one.

[0007] According to the fastening component of the scaffolding described above, the positioning bolts one, three and two are all threaded with nuts.

[0008] According to the fastening component of the scaffold, a second connecting rod is correspondingly fitted inside the upper fixing ring, and a first connecting rod is fitted inside the lower fixing ring.

[0009] According to the fastening component of the scaffolding, both the upper and lower ends of the fixing ring are threaded with screws, and the inner end of the screw is rotatably connected to an arc-shaped plate.

[0010] According to the fastening component of the scaffolding described above, a rubber pad is installed at the inner end of the arc-shaped plate.

[0011] The above solution has beneficial effects: 1. This device uses positioning bolts and nuts for the first locking at the opening end of the fixing ring, while an adjustable screw drives an arc-shaped clamping plate inside, which, together with a rubber pad, forms a second flexible locking on the connecting rod. This synergistic effect of rigid locking and flexible clamping achieves double fixation of the connecting rod, effectively avoiding the loosening problems that easily occur with traditional single locking methods, greatly enhancing the joint stiffness and deformation resistance, and ensuring the structural integrity of the scaffolding under complex loads.

[0012] 2. In this device, the connectors and columns achieve rapid alignment and installation through pre-set screw holes and positioning bolts, eliminating the need for on-site welding or complex positioning procedures. Furthermore, the installation blocks and positioning blocks adopt a plug-in design, coupled with standardized bolt connections, greatly simplifying the overall assembly process. This modular and standardized design concept not only significantly reduces installation difficulty and time costs but also allows components to be flexibly reconfigured according to different construction needs, greatly improving the adaptability and reusability of the scaffolding system.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Connectors 4 are fitted onto the four columns 2. Positioning bolts 315 are threaded into the internal threads of the connectors 4 and columns 2. Mounting component 1 3 is fixedly connected to the top of the connector 4, and mounting component 2 5 is fixedly connected to the lower end of the connector 4. By using positioning bolts 315 and nuts, the connectors 4 can be quickly locked onto the columns 2. Furthermore, the columns 2 have screw holes for mounting the connectors 4, enabling rapid installation. Mounting component 3 and mounting component 5 are both fixedly connected to one end of mounting block 8. Mounting block 8 has an internal mounting groove 16, and a positioning block 17 is correspondingly positioned inside the mounting groove 16. A fixing ring 6 is fixedly connected to the other end of positioning block 17. Positioning bolt 2 14 is threaded into the internal parts of mounting block 8 and positioning block 17. Positioning bolt 1 13 is threaded into the open end of fixing ring 6. Nuts 10 are threaded into positioning bolts 13, 15, and 14.

Next, the positioning block 17 is aligned with the mounting groove 16 inside the mounting block 8, and it is locked using positioning bolts 14 to ensure quick installation of the fastening components. Finally, connecting rod 7 and connecting rod 9 are passed through the two sets of fixing rings 6 sequentially. Inside, rotating the screws 18 at both ends drives the arc plate 11 to move inward. The arc plate 11 and the rubber pad 12 can fix the two connecting rods. Finally, rotating the positioning bolt 13 and the nut 10 gradually locks the opening end of the fixing ring 6, completing the double locking and fixing of the two sets of connecting rods to ensure the support effect and overall strength of the scaffold. The fastening components in this device are installed on the column 2 by bolts, which facilitates quick disassembly and assembly according to different construction conditions, improving the applicability and convenience of the device.
