Space-saving installation compatible expandable device "Hinodakutairu Joint α"
Maintains durability, water tightness, and driving safety for a long period of time with performance in accordance with the road bridge specification. Also available in a snow load region compatible type [NETIS registered product].
The "Hinodakutairu Joint α" is a bridge expansion device that achieves a durability equivalent to 30 years (based on our tests) through unique cast iron technology. Additionally, this product has been registered with NETIS (QS-210051-A). This time, we would like to introduce three series products that can be installed in a compact space: "SCV/SCVJ/CCV types." The "SCV20," designed for ultra-narrow spaces, achieves a height of 75mm and a width of 380mm, resulting in approximately 56% space savings compared to our previous models. 【Features】 ■ Applicable to bridges with thin deck slabs that were previously difficult to install ■ Reduces the amount of concrete removal, thereby decreasing waste output ■ Features high water tightness, with a cast iron integrated load support plate placed to protect the waterproofing material from compressive forces from above ■ The surface of the fingers has a slip-resistant structure, allowing for safe driving even in rainy conditions *For more details, please refer to the catalog.
