Hongxiang Cup-lock Scaffold Joint Pin is a core force-transmitting component for vertical connection. It is integrally formed using a seamless steel pipe hydraulic integrated reinforcement process, eliminating secondary welding and riveting. It consists of a three-section integrated structure： a lower insertion area, a middle limiting protrusion ring, and an upper insertion area. Dimensions strictly conform to the mandatory parameters for pole connection in JGJ166-2016.
Cup-lock Scaffold Joint Pin Operation Features： Quick manual connection, eliminating the need for measurement and verification. The visible limiting protrusion ring replaces measuring tape measurements, allowing a single person to complete the connection of a single pole in 3 seconds, without requiring a dedicated person to check the insertion depth. Ordinary unlimited-position connectors require measuring tape verification of a minimum insertion length of 110mm for each pole, increasing the time for assembling poles for a 1000㎡ full-span scaffold by 40%. Using this product eliminates the measurement step, shortening the erection cycle of the same scale scaffold by 2-3 days. During rush periods, this avoids delays and penalties. Ordinary workers can operate it independently after short-term training, alleviating labor shortages on construction sites. Smooth chamfering without jamming, non-destructive disassembly and reuse. Precise chamfering at both ends of the rod ensures smooth insertion and removal of the upright. A uniform 70μm galvanized layer prevents rust and adhesion. Disassembly allows for easy separation by simply lifting the upper upright, eliminating the need for grinding, hammering, or cutting. Both the connecting rod and the upright can be completely recycled for reuse. In contrast, simple welded ring connecting rods often rust and jam after a year, requiring forceful cutting for disassembly, resulting in the simultaneous scrapping of the upright and connecting rod, doubling material consumption.
Integrated design with no loose parts, extremely low material loss. The complete unit eliminates disassembly accessories. Project final inventory only counts the total number of connecting rods for the upright, resulting in a single-project loss rate of less than 5%. Traditional split-type connectors have a loss rate exceeding 30%, requiring rental companies to spend significant sums annually on replacement parts. The standardized cylindrical shape facilitates bundling and packaging, resulting in higher overall vehicle loading capacity and reduced single-trip logistics costs. Leveraging Renqiu's mature local logistics network, same-day delivery is possible in North China, and large-volume orders (thousands of tons) can be fulfilled within 48 hours from transit warehouses in Southwest and East China, significantly reducing lead times.
Unified standard dimensions ensure complete compatibility between new and old components. CNC straightening and chamfering production lines maintain consistent tolerances, eliminating jamming and excessive gaps when connecting older cup-lock uprights to new components. Rental warehouses no longer require separate storage of new and old materials, reducing outbound sorting manpower by half, and eliminating the need for component screening during cross-site transfers.
The Cup-lock Scaffold Joint Pin offers significant safety advantages.
First, vertical force transmission eliminates the risk of eccentric settlement. The double-layered, uniform interlocking structure transmits loads along the upright's axis, preventing one-sided wall compression and indentation. This ensures uniform settlement of all uprights in the scaffolding, eliminating the risk of localized collapse. Non-standard thin-material connecting rods with excessive gaps cause upright tilting, which can lead to localized scaffolding shifts during long-term pouring. Second, the integrated pier reinforcement has no weld seams, eliminating the risk of convex ring detachment and failure. With no weak weld points, the convex ring will not tear even under hammering during loading and unloading or long-term repetitive pressure, preventing major accidents such as pier joint separation from the structural source. This makes it suitable for long-term construction projects in water conservancy and bridges. Third, the visible limiting structure reduces the difficulty of on-site safety inspections. No measurement is needed during erection and acceptance; the insertion depth can be determined by the position of the convex ring, reducing the frequency of rectification for illegal erection and meeting the standardized acceptance requirements of central enterprises and municipal supervision. Fourth, multiple quality inspections throughout the entire process ensure compliance with key infrastructure projects. Each batch undergoes three mandatory tests： axial compression resistance, repeated insertion, and salt spray testing. Third-party inspection reports for supporting components are provided, and all warehousing and on-site sampling are traceable.
Practical Applications of Cup-lock Scaffold Joint Pin： Domestically, it covers residential buildings, industrial plants, municipal tunnels, overpasses, and pumped storage water conservancy projects; overseas, it covers infrastructure projects in Russia, Turkey, Ivory Coast, the UK, Indonesia, etc., and is compatible with domestic JGJ166 standards and mainstream overseas formwork construction and testing standards. Large-volume procurement by leasing companies enables unified turnover and matching of cup-locking poles, connecting rods, and upper and lower cups; centralized procurement by general contractors provides a one-stop solution for all components; and export components can pass local quality inspections without secondary modifications.
