The abbreviation of plug-in, bridge expansion joint, is also called plug-in cast steel bridge expansion joint or socket-type cast steel bridge expansion joint. The specifications range from ~. This product is customized with various intersection angles according to different drawing design requirements. Bridge expansion joints adapt to the requirements of longitudinal and transverse expansion variables. Their advantages are as follows: The multi-directional and interlaced arc-shaped telescopic arms and telescopic backs between the joints ensure that the transmission of driving force is uninterrupted and the joint direction is The vertical angle 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 longitudinal and transverse expansion displacement flexible and completely eliminates the trouble of rattling noise. .
.The gaps are filled with polymer nano-elastomer material, which has good elasticity, prevents dust and water seepage, and effectively absorbs vibration and noise caused by impact force, thereby easing the long-term jamming of the bridge due to sand and gravel. Under load fatigue, it achieves the purpose of maintenance-free and easy maintenance, and ultimately reduces the later bridge maintenance costs
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. Processes such as shaping and low-temperature molding enable the telescopic body to adapt to changes in various temperature conditions without deformation, with good stiffness, easy installation, and excellent flatness
. The telescopic arm is multi-directional in design and is suitable for bridges with various intersection angles. Telescopic deformation, wide application range:
. There is a 3-degree support arm designed under the telescopic arm, which makes the telescopic arm more durable and safer when it bears heavy wheel loads.
