The main features of arc-shaped butt-type bridge expansion joints:
. The multi-directional and interlaced manner of the arc-shaped telescopic arms and telescopic backs between the joints ensures that the transmission of driving force is uninterrupted and the vertical angle of the joint is It becomes a multi-directional small intersection angle, which effectively disperses the impact force between the wheel and the expansion joint, greatly reduces the vibration and noise caused by the impact force, and makes the vertical and horizontal expansion displacement flexible and completely eliminates the trouble of rattling noise.
.The gaps are filled with nano-elastomer material, which has good elasticity, prevents dust and water seepage, and effectively absorbs vibration and noise caused by impact force, thus easing the bridge's long-term load due to sand and gravel stuck. fatigue, achieving the purpose of maintenance-free and easy maintenance, and ultimately reducing the cost of bridge maintenance in the later stage
3. The expansion bodies on both sides of the expansion joint are integrally formed from high-quality precision cast steel, which has been precision cast, simmered, and hot-pressed. , low-temperature molding and other processes, so that the telescopic body can adapt to changes in various temperature conditions and remain deformed, with good stiffness, easy installation, and excellent flatness
. The telescopic arm is multi-directional in design, adaptable to telescopic deformation of bridges with various intersection angles. , wide range of application:
. There is a 3-degree support arm designed under the telescopic arm, which makes the telescopic arm more durable and safer when bearing heavy loads on wheels. < r::\~\~\~\\\3
