Cast iron expansion joint "Hinodakutairu Joint α (CV type)"

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.

Cast iron expansion device "Hinodakutairu Joint α (SCVJ type)"

Cast iron expansion device "Hinodakutairu Joint α (SCVJ type)"

Cast iron expansion device with snow removal grader-compatible guide plate that can be installed within the pavement thickness! [NETIS registered product] Space-saving installation series (for snow-prone areas)

The "Hinodakutairu Joint α (SCVJ Type)" is a bridge expansion device made of cast iron, designed to achieve a durability equivalent to 30 years through unique casting technology (suitable for snowy regions). It is a steel load-bearing type that can be installed within the thickness of the pavement (cut depth of 80mm) without removing the existing deck slab. This device accommodates the installation on thin deck slabs of small to medium-sized bridges, which could only be addressed by conventional materials or butt-type rubber joints. In addition to the guiding plates arranged on the side of the product body, a sloped shape to prevent grader collisions has been added to the top surface of the body. These two structures mitigate the impact during grader collisions from all angles. 【Features】 ■ Can be installed within the pavement thickness (cut depth of 80mm) ■ No need for special equipment arrangements ■ Achieves a durability equivalent to 30 years through unique casting technology ■ Protection of waterproof materials with load-bearing plates and dustproof materials ■ High waterproofing at the connection surfaces ■ Applies a slip-resistant structure developed for manhole covers ■ Minimal change in slip resistance values ■ Mitigates impacts from grader snow removal vehicles ■ NETIS registered product (QS-210051-A: Space-saving expansion device) *For more details, please refer to the PDF document or feel free to contact us.

Cast iron expansion device "Hinodakutairu Joint α CV Type"

Cast iron expansion device "Hinodakutairu Joint α CV Type"

High water resistance at the connection surface! Reduced life cycle costs through partial replacement with a bolt fastening structure.

The "Hinodakutairu Joint α CV Type" is a cast iron expansion device that achieves a durability equivalent to 30 years through its unique cast iron technology. The bolt fastening structure allows for partial replacement, reducing lifecycle costs. It is possible to protect the water-stopping material with a load-supporting plate and dustproof material. The water-stopping structure at the connection surface is designed to minimize gaps by compressing the protruding water-stopping material, effectively preventing leakage from the connection surface. 【Features】 ■ Maintainability: Reduced lifecycle costs through partial replacement with a bolt fastening structure ■ Durability: Achieves a durability equivalent to 30 years through unique cast iron technology ■ Water-stopping capability: Protection of water-stopping material with a load-supporting plate and dustproof material ■ High water-stopping capability at the connection surface ■ Safety during passage: The semi-circular shape mitigates impact during vehicle passage *For more details, please refer to the PDF document or feel free to contact us.

Bridge Cast Iron Expansion Device "Hinodakutairu Joint α"

Bridge Cast Iron Expansion Device "Hinodakutairu Joint α"

Significantly extend the lifespan of bridges and drastically reduce replacement time! During replacement work, a 30% reduction in construction time and an expected reduction of about 20% to 50% in construction costs can be achieved!

**Contributing to the Long Lifespan of Bridges!!** The "Hinoductile Joint α" is a bridge expansion device that excels in replaceability, durability, and driving safety. The CV type, part of the lifecycle cost (LCC) reduction series, allows for the replacement of the product body (only the cast iron part) without the need for extensive removal of the foundation mortar during the next replacement, thereby reducing construction costs and shortening construction time. Compared to replacing with conventional bridge expansion devices, you can expect: ✔ Approximately 30% reduction in construction time ✔ Approximately 20% to 50% reduction in construction costs!! (for the CV type) **Features (LCC Reduction Series)** ■ The main body is made of Hinoductile cast iron, which has excellent material properties (achieving a durability equivalent to 30 years!) ■ LCC reduction through partial replacement (only the main body) using a bolt connection structure ■ A load-supporting plate formed from a cast iron integrated structure that maintains watertightness for a long period ■ High water-stopping ability at product connection surfaces ■ Surface features designed for slip resistance, ensuring safe driving even in rainy conditions ■ Contributes to the long lifespan of bridges *For more details, please refer to the catalog or feel free to contact us. We will propose suitable products tailored to installation conditions and environments, including other product series.*
