FAQ
Q: What bridges are modular expansion joints suitable for?
A: Suitable for long span highway bridges, river and sea crossing bridges, highway interchanges, urban viaducts and expressways, heavy traffic bridges, continuous girder and continuous rigid frame bridges, large interchanges and ramp bridges, etc.
Q: What is the expansion capacity range of modular expansion joint?
A: The common expansion capacity range is 80mm to 1200mm, determined according to bridge design calculation. Other expansion capacities can also be customized according to project requirements.
Q: How is the expansion capacity of modular expansion joint determined?
A: The expansion capacity is calculated based on temperature variation, concrete shrinkage and creep, prestress, and load effects, and then configured according to actual project requirements.
Q: How is the number of center beams configured?
A: The number of center beams is configured according to the calculated expansion capacity of the bridge. A larger expansion capacity requires more center beams to achieve multi gap linkage and evenly distribute movement.
Q: Can the rubber sealing strip be replaced individually?
A: Yes. The rubber sealing strip is an independent component and can be replaced individually according to wear or aging conditions during maintenance.
Q: What are the main features of modular expansion joints?
A: Multi beam linkage structure ensures uniform gap movement; reliable waterproof sealing; suitable for heavy traffic; adaptable to longitudinal movement and certain vertical and horizontal rotation; modular design allows flexible configuration according to project requirements.
Q: Can it be customized according to project drawings?
A: Yes. Cross section size, expansion capacity, anchoring system, and installation dimensions can be customized according to project design drawings.
