Pot Bearing
PRODUCT OVERVIEW VHB pot bearing made by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are in compliance with standards (TCVN 10268:2014, AASHTO LRFD: 2007 Section 18, ASTM D521203, BS5400, EN1337, KS4420). VHB pot bearing is capable of withstanding high loads, displacements and wide angle rotation. This type of bearing is suitable for middle-range span structure, continuous bridge structure etc. with a load capacity of 60000kN or above depending on projects requirements. VHB pot bearing has well-shaped structure, superior design, which is convenient for installation and maintenance during operation 2. PRODUCT CHARACTERISTICS VHB pot bearing is comprised of 4 main parts: top plate, piston, pot plate and elastomeric pad. The elastomeric pad is placed inside of pot plate, under the pressure of the load, the elastomeric pad experiences the temporary deformation inside the pot plate volume, it is capable of withstanding the forces and allows the movement as well as rotation along horizontal axis. Piston and pot plate work as the connecting parts between the structures. Besides, the plus guiding bar can be designed to limit or allow the movements as required from the structures. Pot bearing is divided into 2 main types: Fixed pot bearing and sliding pot bearing. Fixed pot bearing: The bearing only allows the head of structure to have rotary movement and transfers the pressure through a fixed point. Sliding pot bearing: This type of bearing, including free sliding bearing and guided sliding bearing, allows the head to have both rotary movements and transversally or multidirectional movements. To ensure the long-life durability, VHB pot bearing is protected against corrosion by the following methods: two-component epoxy coat, PU-based painting (Polyurethane), hot dip galvanization according to ASTM A123 standards and especially the Al Mg spraying method (at the ratio of 5% Al and 95% Mg) which ensures the anti-corrosion durability of up to 100 years, proven by salt-spraying test in 6000 hours (8-hour dry-wet cycle repetition) under ASTM B117 standards Dimensions of upper plate in longitudinal direction Dimension of center point of anchor bolts of the upper plate on longitudinal direction B: Dimension of the upper plate on transverse direction Dimension of center point of anchor bolts of the upper

PRODUCT INFORMATION Based on the characteristics, VHB pot bearings are divided into 3 types:
1. Product Overview VSR Elastomeric Bearings made by Vinh Hung investment and production Co., Ltd (Vinh Hung IP) are in compliance with TCVN 10308: 2014, AASHTO LRFD Section 18, AASHTO M 251 96 (2011), BS5400, EN1337, KSF4420 VSR Elastomeric Bearings have been used in road bridge constructions, with a maximum load of 5000kN. 2 PRODUCT CHARACTERISTIC Elastomeric bearings are 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 bearings are simple geometric structures, bringing convenience during the installation, operation and maintenance. In addition, this type of bearing provides high resistance of vibrations impacted to the bridge span structures and piers.
1. Product Overview VHC spherical Bearings/ Bridge bearing manufactured by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are capable of withstanding the high loads and movements suitable for structures requiring the rotary angle equal or bigger than 0.015 rad in all directions. VHC spherical bearings are designed and manufactured according to current standards such as: TCVN 11823, AASHTO LRFD, ASTM D5977, EN 1337, 2. PRODUCT CHARACTERISTICS VHC spherical bearings/ bridge bearing possesses a bottom plate (6) which has a PTFE sliding plate (4) on it is upper curved surface. A convex calotte (5) is placed on top of this, which, thanks to it is polished hard-chromium plated surface, can slide within the lower part with low friction, thus facilitating rotations about every axis. A second sliding plate of PTFE (4) is recessed into the upper surface of the calotte. Together with the upper plate (2) above it, this accommodates longitudinal and/or transverse sliding movements of the superstructure, if required. To reduce sliding resistance to a minimum, the lower surface of the top plate features a polished stainless steel sheet. In the case of bearings which should allow movement along one axis only, the direction of movement is controlled by guiding bars (3). In the case of fixed bearings, the top plate does not have a stainless steel sheet. The bearing is connected to the superstructure and the substructure by means of anchor dowels (1) or threaded sleeves (depending on design), or alternatively by means of separate anchor plates with shear studs. To ensure the long-life durability, VHC spherical bearings are protected against corrosion by the following methods: coating with two-component epoxy, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg spray coating method (at the ratio of 5% Al and 95% Mg) which ensure the anti-corrosion durability of up to 100 years, this method is proved by the salt-spraying test in 6000 hours (8-hour dry-wet cycle) according to ASTM B117
