1. Summary
The Steel monoDBSTM) is the product developed under combined merits of former monowith new monothe upper plate of rail joint is designed as Monoshape and it is manufactured as one body or min 1m. The DBSTM has the same performance as the Single-Rail joints and has added a wave shape to the upper surface for increased driveability.
2. Features
The waterproof rubber seal between rail beams is put in the rail groove processed in the same way as a rubber seal, playing its waterproof role perfectly. The spacing between rail beams can accommodate 30 to 100 mm depending on site conditions.The same structure as single rail so it is applied to diversity bridges such as horizontal, longitudinal,transverse, skewed bridge and curved bridge.Full waterproof functionCustomized designApproved high-quality materialsMaterial is semi-permanent.DBSTM is manufactured with a rubber seal as one body so the waterproof is exnt.The upper surface is the same shape as former monoand the traffic ability is superior.
3. Waterproof
For the implementation of the perfect waterproof function of expansion joints, waterproof rubber seals are put in the rail grooves processed in the same way of rubber seals. So, water leak is perfectly prevented. It is easy to assemble and repair the diamond-shaped waterproof rubber seals that have the exnt function to prevent water from leaking to the bottom of an expansion joint.
4. Anti-corrosion
As for the surface treatment of structural steels, hot dip galvanizing is applied to prevent salt stress and corrosion in accordance with KS D 8308 Standards. Compared to coating, this treatment guarantees exnt corrosion-resistance and adhesion. The thickness is 85μm, ensuring about 45 years of endurance.
