bridge expansion joint

Expansion joints have the demanding task of bridging the movement gaps in the carriage way and foot paths of a bridge structure. They
must be able to accommodate all the movements of the bridge without creating any constraint forces within the structure. Simultaneously,
expansion joints must be able to ensure the safety of traffic and they must maintain a continuous water tight connection along the bridge surface.

Since BAOLI invented the modular expansion joint more than 20 years ago, it has been successfully installed in hundreds of
bridges world-wide. The BAOLI modular expansion joint can accommodate movements in excess of 1200mm.

Description of Modular Expansion Joint for Bridge:
Modular Bridge Expansion Joint separates the structural elements above the basic, and sets apart appropriate gap between both sides in order to ensure the structural elements on both sides of Modular Bridge Expansion Joint free flexible in horizontal direction. The wide of sew is always 20-40mm. And then fill in thermal insulation materials.

a) Building height is low, and the structure is simple.

b) has performance of flexible stretch and safety.

c) has performance of easy installation for construction and low price.

Application of Modular Expansion Joint for Bridge:

Modular Bridge Expansion Joint is used in Highway bridge decks, Service ramps, Multi-storey car parks and so on.

It is used to prevent buildings or bridges appear some cracks because of climate change.
