It makes bridge smooth and seamless, and it's good for preserving, cleaning and moving snow.
The structure is simple, no need to have special stretch frame and anchoring steel bar. Construction is convenient and fast.
It could absorb all kinds of deformations and shaking. And its damping property is high and it's good for bridge shock absorption.
Best sealing and waterproof property and anti-acid-base and corrosion.
Low cost of construction, durable and remarkable economic benefit and social benefit.
Application
Rubber bridge expansion joints for movements of up to 60 mm apply to normal bridges. Compared with expressway, rubber bridge expansion joints are more suitable for being installed on the flyovers. They are also good choices for building new bridges.
Expansion joints are structural devices used in bridge and road construction to accommodate the expansion and contraction caused by temperature changes, vehicle loads, and foundation settlement. Here are several common types of expansion joints:
1. Rubber Expansion Joints:
- Made from rubber materials, they possess good elasticity and flexibility.
- Suitable for small bridges and roads as they can handle smaller expansion amounts.
- Easy to maintain but may not be as durable as other materials.
2. Finger Joints:
- Composed of a series of interlocking metal plates, similar to the teeth of a comb.
- Suitable for medium-span bridges and can withstand larger expansion amounts.
- Have high load-bearing capacity and durability, but installation and maintenance can be more complex.
3. Modular Expansion Joints:
- Consist of prefabricated modules that can be combined and adjusted as needed.
- Suitable for bridges of various spans, especially large bridges.
- Quick to install, easy to maintain, and have good durability and adaptability.
4. TST Expansion Joints (Thermal Stress Absorber Type Expansion Joints):
- Also known as thermal stress absorber expansion joints, designed to absorb stresses caused by temperature changes.
- Typically used for highways and large bridges, capable of accommodating significant temperature variations.
- The structure is more complex, but it effectively reduces bridge damage caused by temperature changes.
Each type of expansion joint has its specific application scenarios and advantages. The choice should be based on a comprehensive consideration of the bridge's design requirements, expected expansion amount, environmental conditions, and budget.
