Reduce noise and vibration generation! Easy to install due to its simple structure and manageable weight.
The "Super Guide Top Joint SGTd Type" is an expansion device for bridges and elevated roads that exhibits smooth and excellent driving performance due to its extremely small exposed surface area. It connects water-stop rubber through mold vulcanization and adhesive bonding, allowing for continuity. Its unique tooth structure provides seismic resistance against displacements (vertical and shear displacements) during earthquakes. Its simple structure and manageable weight make installation easy, and a refresh method for rubber part replacement maintenance has been established. 【Features】 ■ Vertical-type double-sided tooth structure / Load-supporting type for durability and reliability ■ Unique tooth structure provides seismic resistance against displacements (vertical and shear displacements) during earthquakes ■ Exhibits smooth and excellent driving performance, reducing noise and vibration generation ■ Connects water-stop rubber through mold vulcanization and adhesive bonding, allowing for continuity ■ Easy installation due to simple structure and manageable weight *For more details, please download the PDF or feel free to contact us.
