**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.

The "Hinodakutairu Joint α (for sidewalks)" is a sidewalk expansion joint that allows for the free selection of surface materials to match the surrounding landscape. One of the challenges with sidewalk expansion joints has been that post-installed concrete does not blend well with the surrounding asphalt pavement or colored tiles. This product allows for the selection of pavement surfaces that match the landscape of the installation site, and because it can fill the surface material up to the vicinity of the expansion joint, it enables construction with excellent aesthetic quality. 【Features】 ■ Allows for the selection of pavement surfaces that match the landscape of the installation site ■ Ensures water-tight performance similar to that of roadway expansion joints *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

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.

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.

The "Hinodakutairu Joint α (CVJ Type)" is a cast iron expansion joint that achieves a durability equivalent to 30 years through its unique cast iron technology. (Includes a guide plate compatible with snow removal graders) By bolting the main body of the expansion joint to the slab, partial replacement of only the main body can be performed during the next replacement.

The steel widening ground cover allows for installation with a setback of 250 mm from the front of the ground cover to the front of the main crossbeam by anchoring the ground cover and railing support columns through a high-strength, uniquely structured cast iron widening base. Between the columns, a steel reinforcement substrate rail is covered with a corrosion-resistant steel plate ground cover, allowing for vehicle guidance even when vehicles drive over it. This enables construction at night with minimal vehicle traffic restrictions and is suitable for small bridges in narrow areas where a setback is necessary, allowing for construction without concrete. **Features** - **Compliance with construction limits:** 250 mm setback for railings with a 300 mm narrow ground cover. - **Short construction period:** Construction from within the bridge and no curing time required, allowing for a shortened construction period. - **Lightweight:** Approximately 90 kg/m lighter compared to concrete widening. - **Low load:** Structure designed to minimize impact load on the ground cover during vehicle collisions. - **Aesthetic appeal:** Provides an open and comfortable driving space. *Note 1: Installation may not be possible if the concrete strength does not meet the design strength. Note 2, 3: Construction period and weight may vary depending on the conditions of the ground cover renovation work.* (This product is a joint development by Hinode Waterworks Equipment Co., Ltd. and Sekisui Plastics Co., Ltd.)

The "Hinodakutairu Joint α Ground Cover Water Stop (Embedded Type)" prevents water leakage from the ends by raising a water stop material at the ends of the expansion device and embedding it within the ground cover.
