The axial multi-directiona​l displacement comb plate expansion device is mainly used in bridge engineering, as follows: 1. Highway bridges: Vehicles on highways carry heavy loads and travel at high speeds. Bridges are affected by factors such as temperature differences, wind force, and vehicle loading, which can cause complex displacements in the longitudinal, horizontal, and vertical directions.
The axial multi-directional displacement comb plate expansion device is mainly used in bridge engineering, as follows:
1. Highway bridges: Vehicles on highways carry heavy loads and travel at high speeds. Bridges are affected by factors such as temperature differences, wind force, and vehicle loading, which can cause complex displacements in the longitudinal, horizontal, and vertical directions. The axial multi-directional displacement comb plate expansion device can adapt to these displacements, ensure the normal operation of bridge expansion joints, enable vehicles to pass smoothly and safely through the beam end expansion joint area, and extend the service life of the bridge. For example, the Qingshuihe Extra Large Bridge on the Wuxuan section of G5011 Wuhe Expressway considered using a new type of adaptive multi-directional displacement comb plate expansion joint device when replacing expansion joints, which has accumulated practical experience for the application of such devices in large-span bridge engineering.
2. Urban bridges: Urban bridges also face problems such as vehicle loads and environmental temperature changes, and have high requirements for driving comfort and safety. This expansion device can effectively absorb various displacements of the bridge, reduce bumps and vibrations when vehicles pass through expansion joints, improve driving comfort, protect the bridge structure, reduce diseases at expansion joints, and lower maintenance costs.
3. Large cross sea and cross river bridges: These types of bridges have large spans, complex structures, and are more significantly affected by environmental factors such as temperature changes, wind loads, seismic effects, and foundation settlement, making them more prone to multi-directional displacement. The axial multi-directional displacement comb plate expansion device can adapt well to these complex working conditions, meet the displacement needs of bridges in various situations, and ensure the safe operation of bridges.
      In addition, some special building structures that require high structural deformation and need to adapt to multi-directional displacement may also consider using similar multi-directional displacement expansion devices in some cases, but the bridge field is their main application scenario.
