The MS series multi-directional displacement comb plate expansion device is mainly used in bridge engineering. Its functions include meeting the multi-directional displacement requirements of bridges, providing stable support, reducing vibration and noise, enhancing durability, and facilitating maintenance and repair, as follows:
1. Adapt to multi-directional displacement: By setting up "U" bolt groups, multi-directional displacement boxes, ball bearings and other structures, the MS series expansion device can meet the lateral, vertical, torsional displacement and longitudinal expansion requirements of the bridge, ensuring the stability and safety of the bridge structure under the influence of temperature changes, wind force, vehicle loads and other factors.
2. Provide stable support: The comb plates of the device interlock with each other to form a continuous support surface, which can evenly distribute vehicle loads and provide reliable support for the bridge, ensuring smooth passage of vehicles through the bridge deck.
3. Reduce vibration and noise: Polymer damping materials are installed between steel plates and concrete, as well as between steel plates. At the same time, circular arc transition designs are used at the comb end face and root groove to reduce the vibration effects of vehicle loads, effectively reducing the impact vibration on bridges and vehicles, reducing noise pollution, and making driving more comfortable.
4. Enhance durability: The main material is made of low-alloy high-strength structural steel, which improves the compressive and shear resistance of the expansion device. Polymer damping materials have good fatigue resistance and can reduce the repeated impact force of the vehicle on the expansion device. The waterstop is set under the expansion device to avoid direct exposure to the atmosphere. These designs enhance the environmental adaptability of the expansion device and extend its service life.
5. Convenient maintenance and repair: The MS series telescopic device adopts a modular design, with each module having independent functions. When a module is damaged, it can be disassembled and replaced separately without the need to replace the entire telescopic device. The maintenance process does not interrupt traffic, reducing operating costs and improving maintenance efficiency.
