1. PRODUCT OVERVIEW
VSR Elastomeric Bearing made by Vinh Hung investment and production Company Limited (Vinh Hung IP) is in compliance with TCVN 10308 : 2014, AASHTO LRFD – Section 18, AASHTO M 251 – 96 (2011), BS 5400, EN 1337, KS F4420
VSR Elastomeric Bearings have been used in road bridge constructions, with a maximum load of 5000kN.
2. PRODUCT CHARACTERISTIC
Elastomeric bearings is composed of rubber and steel plates which are chemically bonded through vulcanization. The thickness of the bearing is calculated to ensure the load, displacement and rotation as the requirement.
Elastomeric bearing is simple geometric structure, offering convenience during the installation, operation and maintenance. In addition, this type of bearing is capable of withstanding high and sudden shocks, vibrations and pulses from moving load to the span and abutment structures.
Depending on the characteristics of the product, VSR Elastomeric beairngs are divided into 4 types:
- Locate the installation position of the bridge bearing, apply the mortar and cure the mortar until it meets the required strength.
- Install the bearing on the position, check the location, elevation and ﬂatness of the bearing as requirements of project and current standards.
- Install the girder on bearings, check the elevation and connection between the top of bearing and bottom of girder. Complete the installation.
