Seismic Displacement Restraint Device "ST Type T-Stopper"

Structural design that responds to inertial forces during earthquakes is possible! Compatible with both concrete girder bridges and steel girder bridges.

The "ST Type T Stopper" is a displacement restraint device that suppresses displacements in the bridge axis direction and perpendicular to the bridge axis caused by earthquakes. Its structure is simple and has excellent workability, making it compatible with both concrete girder bridges and steel girder bridges. As a measure to prevent the upper structure from falling, this product serves as an effective means to establish a bridge collapse prevention system. Additionally, the anti-corrosion treatment can utilize SG plating and double anti-corrosion SG plating + nylon coating, which have higher anti-corrosion effects than standard galvanizing, allowing for improvements in LCC (Life Cycle Cost). 【Features】 ■ Usable for both concrete and steel girders, enabling structural design according to seismic inertial forces ■ Most parts are manufactured from a combination of rolled steel, allowing for easy design of free shapes ■ Sliding buffer rubber (chloroprene rubber) mitigates horizontal and uplift forces ■ Improvements in LCC can be achieved ■ Depending on various conditions, both standard and uplift force compatible types can be selected *For more details, please refer to the PDF materials or feel free to contact us.
