Advanced Movement Accommodation
These bridge expansion joints are crafted to offer a movement range of up to 80mm (with certain models reaching 100mm maximum expansion). Their adaptable design ensures seamless integration into various bridge structures and allows effective management of thermal fluctuations, structural shifts, and dynamic traffic loads.
Superior Durability and Resistance
With over 25 years of rated service life, each joint is engineered using ASTM A36/A572 steel and premium-grade rubber. The inbuilt features provide high impact strength, outstanding waterproofing (IP68 on seals), excellent fire resistance, and enduring UV stability-all vital for challenging bridge environments.
Efficient Installation and Easy Maintenance
Supplied with compatible anchor bolts and joint sealers, installation of these expansion joints can be completed onsite or with precast methods. Routine maintenance is straightforward, including visual inspections and regular cleaning, ensuring optimal long-term performance even under heavy vehicular loads.
FAQ's of Expansion Joints For Bridge:
Q: How are these expansion joints installed on bridge decks?
A: These joints can be installed either by precast methods or fitted onsite using the provided anchor bolts and joint sealers. Their rectangular, modular design supports compatibility with installation machines, making the process efficient and minimizing bridge downtime.Q: What movement range do the expansion joints accommodate?
A: Depending on the model, the expansion joints manage movement between 10mm and 100mm, with standard capabilities up to 80mm. This flexibility ensures that both minor and significant bridge expansions are effectively covered.Q: When is routine maintenance required for these joints?
A: Routine maintenance, such as visual inspections and cleaning, is typically performed at scheduled intervals, based on traffic volume and environmental conditions. The joints are designed for easy access, enabling swift assessments and upkeep to maximize service life.Q: Where are these expansion joints most commonly used?
A: They are predominantly utilized in bridge decks to close structural gaps and accommodate expansion/contraction due to thermal, dynamic, or settlement movements. Their robust features make them suitable for diverse bridge environments across Korea South and international markets.Q: What benefits does the waterproofing feature provide for bridges?
A: The IP68-equivalent waterproof joint seal offers exceptional resistance against water ingress, preventing corrosion and minimizing maintenance. This protection ensures long-term durability and the structural integrity of the bridge under various weather conditions.Q: How does inbuilt noise control improve bridge performance?
A: Integrated noise dampening materials reduce the sound generated as vehicles traverse the joints. This feature contributes to a quieter bridge environment and enhances user comfort, especially in urban and residential locations.
