      The ordinary noise reducing comb plate expansion device is mainly used in the transportation engineering industry, and also has certain applications in the construction engineering industry, as follows:
1. Bridge construction industry: Ordinary noise reducing comb plate expansion devices are widely used in various types of bridges, including straight bridges, curved bridges, inclined bridges, slope bridges, etc. Especially for urban overpasses and overpasses, due to the high traffic volume and prominent noise pollution problems, high noise reduction requirements are required. The noise reducing comb plate expansion device can effectively reduce the noise generated by vehicles passing through expansion joints and improve driving comfort.
2. Highway and expressway industry: In the construction of highways and expressways, noise reducing comb plate expansion devices are commonly used in the transition sections between roadbeds and bridges, as well as at the expansion joints of long sections. It can adapt to the expansion and contraction deformation of roads caused by factors such as temperature changes and vehicle loads, prevent road cracking, and reduce the noise of vehicles during driving, providing a quieter environment for drivers and surrounding residents.
3. Rail transit industry: In subway, light rail and other rail transit lines, the track structure may also undergo expansion and contraction deformation due to temperature changes and other factors, requiring the installation of expansion devices. The ordinary noise reducing comb plate expansion device can be applied to bridge sections or tunnel bridge connection parts of rail transit, which can meet the needs of track expansion and can reduce the noise of trains passing through and minimize the impact on the surrounding environment.
4. Construction industry: In some high-rise buildings, due to the high height of the building, it is greatly affected by factors such as temperature changes and wind force, and the structure will undergo certain expansion and contraction deformation. The ordinary noise reducing comb plate expansion device can be used at the joints of high-rise buildings, playing a role in buffering and noise reduction, while preventing problems such as cracking caused by deformation of the building.
