What is the purpose of modular multi joint expansion device
Modular multi joint expansion device is mainly used in bridge engineering, and its applications include the following aspects:
1. Adapt to bridge deformation: It can effectively absorb and adapt to the expansion and contraction deformation of bridges caused by temperature changes, concrete shrinkage and creep, vehicle loads, and other factors. For example, when the temperature rises or falls sign
Modular multi joint expansion device is mainly used in bridge engineering, and its applications include the following aspects:
1. Adapt to bridge deformation: It can effectively absorb and adapt to the expansion and contraction deformation of bridges caused by temperature changes, concrete shrinkage and creep, vehicle loads, and other factors. For example, when the temperature rises or falls significantly, the bridge structure will experience thermal expansion and contraction. The modular multi joint expansion device can provide relative displacement space between different parts of the bridge, avoiding excessive stress inside the structure and damage.
2. Ensure driving comfort and safety: Keep the bridge deck smooth even in the event of bridge expansion and deformation, reduce bumps and vibrations when vehicles pass through, reduce impact on vehicles and bridges, improve driving comfort and safety, and also reduce damage to vehicle components caused by bumps.
3. Protecting the bridge structure: preventing rainwater, dust, debris, etc. from entering the interior of the bridge structure, avoiding erosion and damage to components such as beams and supports, thereby extending the service life of the bridge and reducing maintenance costs.
4. Adapt to large displacement requirements: Through the design of multiple sets of joints and special structural construction, it can meet the displacement requirements of large-span bridges or bridge parts with large expansion and contraction. It can provide different specifications of expansion and contraction according to actual engineering needs, and can effectively cope with small displacements to large displacements of hundreds of millimeters.
5. Adapt to complex bridge forms: It has good adaptability to various complex forms of bridges such as bends, slopes, slopes, and widths. The structural connections are usually designed to be both rotatable and sliding, and can be installed and used on different types of bridges to meet the expansion and deformation control requirements of various types of bridges.
6. Distributed load: Under the action of vehicle load, the load can be evenly transmitted to the bridge structure, making the bridge stress more uniform and reasonable, avoiding excessive local stress, and helping to improve the overall bearing capacity and stability of the bridge.
