Earthquake-Resistant Joints (Bridge Joints)

Features

1.Application
Allow expansion of over 200 mm into the Longitudinal(X), Transverse(Y) directions and also Vertical direction movements (Z) in seismic applications

2.Driver Safety
The wheel can maintain the continuity with the flat appearance of the upper plate in the finger type

3.Durability
Row material is strong with an aluminum and steel composite structure and it is composed of a simple beam sliding on the lower plate where the one side of the upper plate is symmetrical so as to prevent the damage of the upper plate with its strong durability from the wheel load and also has an excellent resistance against abrasion and corrosion.

4.Vibration & Noise
The Rubber Seal between the upper plate and lower plate absorbs the shock generated from the contact of the vehicle wheel and reduces the vibration and noise

5.Easy Maintenance
The system consists of a separate unit structure so that it is easy to replace unit by unit in case of problems. Also, in case of leakage due to the Rubber Seal being damaged, its, so called, sliding structure makes it possible to replace the Rubber Seal from under the lower laying gap of the bridge slab(under the bridge); Therefore, this does not generate traffic congestion or any civil claims from drivers.

6.Economical Efficiency
It allows three directional movements of X, Y, and Z of earthquakes and can be reused when the seismic behavior is terminated as long as the seismic damage does not break the bridge itself. In addition, it has a safe structure compared to the existing expansion and has an excellent long-term economical efficiency in the maintenance by making it possible to replace the Rubber Seal only which has the highest frequency of damage.
