Cuplock System

Product catalog summary
Overview: The Cuplock System is a versatile scaffold system used in construction for falsework support structures. It is known for its high leg load capacity and adaptability, suitable for applications like soffit support, access scaffolds, and mobile towers.
System Features: The system features a unique circular node point allowing up to four horizontals to connect to a vertical, enhancing speed and safety. It offers high leg load capacity, quick erection, and systemized bracing, with decking options in steel, timber, and aluminum.
Decking Options:
  • Steel Decking: Includes primary and infill beams with drophead for early striking.
  • Timber Decking: Utilizes durable H20 timber beams with high load capacity.
  • Aluminum Decking: Lightweight, corrosion-resistant, and offers increased productivity.
Load Capacities: Supports up to 55kN leg load, influenced by spacing, height, and bracing. External standards have reduced load capacities compared to internal standards.
Bracing and Stability: Diagonal bracing is essential for stability, with patterns required to meet BS 5975 standards.
Early Striking Technique: Allows formwork removal 3-4 days post-concrete pour, optimizing material reuse and reducing cycle times.
Applications in Multi-Story Buildings: Facilitates efficient formwork and support reuse across floors, requiring additional support for subsequent floors.
Conclusion: The Cuplock System is robust, efficient, and adaptable, offering advantages in speed, safety, and cost-effectiveness.
Cuplock System Assembly Procedure:
  1. Place base jacks and insert the first standard, ensuring ledgers form a 90-degree angle.
  2. Add a second standard and connect with the ledger, forming a right angle.
  3. Complete the rectangle with a fourth standard and two additional ledgers, then add four ledgers to the top and tighten.
  4. Assemble two diagonal braces and add universal jacks and dropheads.
  5. Add decking beams and infill beams, tightening joints.
Dismantling Procedure: Dismantling is the same regardless of early striking. Decking and infill beams are dismantled by striking the drophead wedge, allowing beam removal while maintaining soffit support.
Cuplock System Components:
  • Standards: Made from high-quality steel, with movable upper cups and fixed lower cups.
  • Ledgers: Constructed from steel tubes, available in various sizes.
Technical Specifications:
  • Permissible Axial Load: Varies with free buckling length, max 280 kN.
  • Ledger Load Capacities: Specified for different ledger sizes.
  • Weight and Codes: Detailed for standards, ledgers, with painted and galvanized finishes.
Additional Construction Materials:
  • Aluminum Beams: Types T150 and S150, with specifications on moment of resistance, area, inertia, and weight.
  • Steel Staircases: Various configurations with specified dimensions and weights.
  • Wooden Planks: Available in various lengths and thicknesses, with weight details.
  • Steel Boards: Painted, available in various lengths.
Key Parameters:
  • Young’s Modulus for aluminum beams: 69000 N/mm².
  • Timber weight: 0.75 kg/m.

Horizontal Formwork | Cuplock System Aluminum Beams Decking The benefits of aluminum formwork products compared with their steel and timber equivalents have had a major impact on formwork practice. The light weight of aluminum beams which can weigh as little as one-third of their steel equivalent opens the way to greatly increased site acceptance and productivity. The corrosion resistance of aluminum ensures a long maintenance-free life, further extended by the fact that it cannot be easily cut up on site like timber beams. The two factors of productivity and long material life combine to explain...

Horizontal Formwork | Cuplock System Beam Bracket Beam bracket eliminates full height propping to beam formwork by locating on to slab support verticals. The beam bracket distributes the load throughout the surrounding scaffold structure. Normally, Beam Brackets are used to support internal down-stand beam. The use of beam bracket with jacks accepting beam spanning from one bracket to another can avoid the need of ground based support. Thus saving all the components that would normally be needed below to transfer the beams load to the ground. Beam Bracket The Max. SWL that can be supported by...

Horizontal Formwork | Cuplock System Early Striking with GS System Early striking is a technique whereby the formwork is removed 3 to 4 days after pouring a slab, but the supporting structure of scaffolding or props remains undisturbed until the concrete is strong enough to support its own weight over its full span. Concrete generally takes 28 days to attain its full constructional design strength. Most engineers will only permit the complete support to be removed after about 10 to 14 days, depending on the ambient temperature and cube strength tests. Drophead in Lower Position Tests and studies...
