Modular bridge expansion joints are an indispensable component of modern bridge engineering, and their working principles and design concepts are of great significance for ensuring the safe operation and extending the service life of bridges.
Modular bridge expansion joints are usually composed of multiple modules, each of which is connected to each other through precise design, forming a whole that is both elastic and flexible in expansion and contraction.
These modules mainly include key components such as edge beams, middle beams, cross beams, and linkage mechanisms. The side beams and middle beams are generally made of special-shaped steel, which has high strength and excellent deformation resistance, and can directly withstand wheel loads and transmit them to the main structure of the bridge; The crossbeam plays a role in connecting and supporting the middle beam, ensuring that the expansion joint remains stable under stress; The linkage mechanism is responsible for controlling the expansion and contraction of the expansion joint, enabling it to adaptively adjust according to the deformation requirements of the bridge



Easy installation
The modular design allows for the prefabrication and installation of various components of the expansion joint, making the construction process simple and fast.
Low maintenance cost
Modular design supports prefabricated installation, some products are maintenance free or low maintenance, and require no maintenance for 5-10 years, significantly reducing later maintenance costs
Strong adaptability
Modular bridge expansion joints can adapt to different bridge structures and expansion deformation requirements, and can be adjusted according to actual situations, with high flexibility and versatility
Good waterproof performance
Modular bridge expansion joints usually have waterproof sealing performance, which can effectively prevent rainwater from eroding the internal structure of the bridge and extend the service life of the bridge
Strong seismic performance
Partial modular expansion joints are equipped with limit devices, which can withstand earthquakes of magnitude 7 or above and reduce disaster losses
Good durability
Made of corrosion-resistant materials, it has good durability and can be used for a long time
