For preventing buckling of the rebar cage in cast-in-place piles. A highly reliable, weld-free method backed by approximately 9,000 pile achievements and a safe construction cycle!
The "CUP Method" ensures safety assessments for all piles, including suspension analysis, buckling analysis, and connection part analysis. It determines the position of reinforcement ring components and the arrangement of fittings to prevent excessive loads on the fittings, making it a non-welding method. The risk of buckling is quantified and visualized, allowing for quantitative comparisons. Our company has extensive construction achievements based on method standards, enabling us to propose a safe zone that does not experience buckling based on these achievements. 【Features】 ■ Prevents buckling of the rebar cage in cast-in-place piles. ■ Approximately 9,000 successful cases of CUP method all-casing piles. ■ Economical method through the recovery and reuse (repurposing) of fittings. ■ Excellent workability through bolt fastening. ■ Various applications are possible, such as the assembly of core rebar for semi-rigid connections at the pile head. 〈Patent Information〉 ■ Special suspension reinforcement ring: Design method for reinforcement rings, rebar cages, and rebar cages (Patent 6678806). ■ CUP method buckling analysis: Quantitative comparison through the numerical representation of achievements, visualizing risk (Patent 7128108). * You can view materials introducing issues related to buckling measures for rebar cages via "PDF Download."

Company information
No matter how thick the rebar used is, cast-in-place piles with welded assemblies are affected by stress concentration during an earthquake. The no-welding method has many challenges in ensuring safety during construction, and safety considerations are essential. Our company offers various proposals for reliable no-welding method construction. Super high-rise buildings, bridges, and flood control levees... The piles that support these structures require the no-welding method, which is an indispensable technology for withstanding earthquakes. The CUP method is not a "no-welding fitting." Our company specializes in the development of no-welding methods. *We welcome inquiries for estimates as well. If you send us the rebar layout, we will conduct safety assessments and provide estimates. If you have any concerns regarding no-welding, please feel free to contact us!
