The "spring function composite rubber bearing" is a new type of rubber bearing that can significantly suppress displacements during earthquakes. By dividing the functions required of the rubber bearing between the upper and lower bearings, it achieves a function-separated bearing structure within an integral structure. Like function-integrated rubber bearings, it also excels in constructability. Additionally, it not only allows for the setting of an optimal bearing shape but also enhances horizontal stiffness, which can lead to cost reductions for expansion joints by suppressing displacements during earthquakes. 【Features】 ■ Allows for the setting of any high horizontal stiffness without being affected by compressive stiffness ■ Achieves an economical and effective "function-separated bearing structure" by separating functions vertically ■ Can be used as a seismic isolation bearing (LRB) with higher horizontal stiffness than conventional designs by incorporating a lead plug in the upper bearing *For more details, please refer to the PDF document or feel free to contact us.
