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.
