II Introduction of rubber bridge bearing |
|||
|
Natural Rubber bearing generally consists or interleaving layers of rubber bonded sandwich fashion to steel plates.The whole unit is covered with rubber to afford weather protection. A bridge basically consists of bridge deck supported by piers.In order to avoid over stressing and Damage by movements of vehicle and loading to the piers, bridge bearings are used to accommodate these movements so as to reduce the reaction forces and bending movement to within the safety limits of structure.Natural Rubber is an ideal engineering material for bridge bearings as it is highly elastic and sufficiently soft to accommodate these movements without transmitting harmful stress and also it can absorb and isolate energies from impacts and vibrations. |

|
III Types of rubber bridge bearings |
|||
|
• Laminated bearings - an elastomeric bearing containing steel laminates bonded to rubber • Plain pad bearing - a plain rubber pad containing no steel plates • Strip bearing - a plain pad bearing for which the length is much greater than the width (>10 times) • Pot bearing - a bearing consisting essentially of a block of solid rubber enclosed between a metal Piston and metal cylinder |

IV Advantage and performance of rubber bridge bearing |
|||
|
1 Fine technical performance 2 simple structure 3 low price 4 no maintenance 5 easy to change 6 buffering and shock isolating 7 low building height Elastomeric rubber bridge bearings shall be composed of multiple laminates of elastomeric material separated by steel reinforcing the overall size of the bearings the number of laminates and thickness of laminates are designed in accordance to the requirement of load to be transferred.Bearings having steel plates as reinforcement shall be cast/compression molded / vulcanized as single unit in a mold under pressure and heat. |

|
V Applications of rubber bridge bearing |
|||
|
General elastomeric laminated bearing suits to bridges with span less than 30m and small displacement.Tetrafluoro elastomeric laminated bearing suits to bridges with large span,several spans. According to the performance characteristics of neoprene, it is mainly used in flame retardant products, oil products, weather resistant products, adhesives, etc., for example, building waterproof sheet, building sealing strip, highway caulking material, bridge bearings gaskets, low-voltage wire and cable sheathing, all kinds of sealing products, anti-corrosion lining, adhesive and so on |

|
VI Manufacturing Process of rubber bridge bearing |
|||
|
• Preparation of rubber compound according to specification required • Preparation of steel plates • Application of bonding agent to steel plates • Assembly of compound and plates • Compression moulding • Performance Test • Ready for installation |
|||
|
VII List of bearing types that can be tested in our facilit |
|||
|
• Plain elastomeric bearings. • Laminated elastomeric bearings. • Steel pot bearing • spherical bearings • ptfe sliding bearing |
|||
|
(Important you need) Laminated Bearing designing: |
|||
| Our technical and design team can design right type of bearing based on loads provided design bearing for end applications.On receipt of corbel size, load and movement details of requirements, calculations and bearings sizes can be provided based on results on parameters . | |||
