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.

Cast iron expansion device that can be installed within a pavement thickness of 75mm with a box depth! 【NETIS registered product】 Space-saving installation series.

The "Hinodakutairu Joint α SCV Type" is a cast iron expansion device for bridges that achieves a durability equivalent to 30 years through unique casting technology. It is a steel load-bearing type that can be installed within the pavement thickness (cut depth of 75mm) without removing the existing deck slab. It is suitable for installation on small to medium-sized bridges with thin deck slabs, which could only be addressed by conventional materials or butt-type rubber joints. A packing integrated with a water-stopping material is placed on the connection surface of the main body to prevent leakage at the connection. Additionally, it adopts a slip-resistant pattern that has proven effective in manhole covers. The surface of the box-out section is finished with a Doro Guard, preventing exposed concrete from being visible and maintaining minimal changes in slip resistance values while also excelling in aesthetics. 【Features】 ■ Can be installed within the pavement thickness (box-out depth of 75mm) ■ No need for special equipment arrangements ■ Achieves a durability equivalent to 30 years through unique casting technology (based on our test results) ■ Protection of the water-stopping material with a load-bearing plate and dust-proof material ■ High water-stopping capability at the connection surface ■ NETIS registered product (QS-210051-A: Space-saving installation compatible expansion device) *For more details, please refer to the PDF materials or feel free to contact us.
