The Cuplock Bottom Cup serves as a permanent, fixed load-bearing base for uprights. Optimizing the bowl groove surface and edge dimensions within a standardized bowl-lock erection process, it eliminates the need for additional adjustments or secondary reinforcement. During erection, simply insert the four horizontal bar plugs into the bowl groove, slide down the upper bowl, and tap to lock it in place – the node is then complete.
Key Features of the Cuplock Bottom Cup：
Four-way synchronous support significantly improves node erection efficiency.
A single lower bowl can accommodate four horizontal bars simultaneously, eliminating the need for sequential plug placement. A single person can place the bars in one step, combined with a single hammer tap to lock them in place. Traditional simple shallow-groove lower bowls are prone to horizontal bar slippage, requiring repeated adjustments, increasing the erection time by 40% for the same 1000㎡ full-span scaffold. This product's wraparound bowl groove limiter automatically positions the horizontal bars, eliminating the need for manual support. It can save 2-3 days of erection time for 1000㎡ formwork, offering significant advantages during rush periods.
Permanently welded as a single unit, eliminating the loss or damage of small parts. The lower bowl and uprights are welded together, unlike the upper bowl and pins which are scattered parts. This eliminates the risk of loss or replacement during project completion, resulting in virtually zero loss of parts per project. Inventory in the leased warehouse only requires counting the uprights; there's no need to separately inventory the lower bowl parts, significantly reducing warehousing and sorting manpower.
Galvanized bowl grooves slide smoothly, ensuring long-term use without jamming or rust. A uniform 70μm zinc layer covers the curved surface of the bowl groove, allowing for smooth insertion and removal of the crossbar plug. Rust will not cause the rods to jam, and disassembly requires no grinding or cutting. Both uprights and crossbars can be completely recycled for reuse. In contrast, a simply painted lower bowl will rust and become uneven within a year, the plug will become stuck and unable to be removed, and the rods will be rendered unusable, doubling material consumption.
Standardized modular design ensures complete compatibility between new and old uprights. CNC molds standardize bowl groove curvature, inner diameter, and welding base dimensions, eliminating compatibility issues between old inventory uprights and newly produced uprights. Rental companies can allocate uprights across construction sites without sorting or screening, significantly improving loading and unloading efficiency.
Cuplock Bottom Cup's core safety advantages：
First, a permanently fixed base eliminates the risk of joint detachment. The lower bowl buckle is welded to the upright, eliminating the issues of the upper bowl buckle sliding or floating. It bears the full support force of the crossbars throughout. Even if the upper bowl becomes slightly loose, the crossbars are still restrained by the lower bowl, preventing instantaneous detachment and greatly reducing the probability of collapse.
Second, balanced four-way force distribution prevents localized upright crushing. The load of the four crossbars is evenly distributed throughout the bowl, preventing concentrated force on one side that could cause upright wall indentation. The frame settles evenly, eliminating the risk of localized tilting.
Third, thickened cast steel + full welding provides double resistance to wear and tear, making it suitable for high-frequency rental turnover. The Cuplock Bottom Cup is resistant to cracking and weld detachment during on-site loading, unloading, hammering, and stacking. Rental companies can utilize it long-term without frequent replacement of uprights, significantly reducing maintenance and re-procurement costs.
Fourth, it features comprehensive compliant testing, making it suitable for key projects of central state-owned enterprises. Each batch of cups undergoes pressure resistance, weld strength, and salt spray testing, accompanied by third-party component inspection reports, meeting all requirements for on-site inspections and warehousing qualifications from China Railway and municipal supervision companies.
Application Scenarios of Cuplock Bottom Cup Products： Large-span, full-span high-formwork support for factories and basements： Multiple layers of densely packed horizontal bars rely entirely on the bottom cup to bear the heavy concrete load, ensuring stable joints without slippage and preventing scaffolding subsidence during top slab pouring.
High-rise residential double-row exterior wall scaffolding： Multiple layers of horizontal horizontal bars on the facade are permanently restrained by the bottom cup, resisting lateral pull from strong winds at high altitudes, eliminating the need for long-term inspection and reinforcement.
Cast-in-place bridge box girder and pier support： Bridges can withstand continuous heavy loads for dozens of days; the hot-dip galvanized cup grooves are corrosion-resistant, allowing for continuous multi-span utilization without the need to replace uprights.
Temporary support for subways and underground utility tunnels： In damp, water-filled underground environments, the zinc coating prevents corrosion, significantly reducing the frequency of safety inspections in confined spaces.
Overseas coastal infrastructure projects： Exported to high-salt coastal areas such as Russia, Turkey, and Indonesia, its long-lasting corrosion protection adapts to harsh local climates and meets overseas formwork inspection standards.
