Cast iron expansion joint "Hinodakutairu Joint α (CV type)"
High water resistance! Reduced lifecycle costs through partial replacement with a bolt fastening structure!
The "Hinoductile Joint α (for road use, general regional type)" is a cast iron expansion device that excels in replaceability, durability, and running safety. By bolting the main body of the expansion device to the slab, it allows for partial replacement of only the main body during the next replacement, enabling the reuse of the foundation mortar and reducing the life cycle cost (LCC)! Additionally, made from Hinoductile cast iron, which possesses strength and elongation, it features an optimized structure that enhances durability. The surface layer incorporates a textured structure similar to the ASD (Anti-Slipping-Design®) developed for manhole covers, providing slip resistance that lasts for an extended period, equivalent to or better than wet asphalt. 【Features】 ■ Reduced life cycle costs through partial replacement with a bolted structure ■ Achieves durability equivalent to 30 years through unique cast iron technology ■ Load-bearing plates and dust-proof materials ■ Semi-circular shape mitigates impacts during vehicle passage ■ Applies slip-resistant structure developed for manhole covers ■ Protection of waterproofing materials with minimal changes in slip resistance values ■ High waterproofing at connection surfaces *For more details, please refer to the PDF document or feel free to contact us.
