Plug-in cast steel bridge expansion joints or socket-type cast steel bridge expansion joints are bridge expansion joints with various angles that can be customized according to different drawing design requirements to adapt to longitudinal and transverse expansion variable requirements. Its advantages are as follows: .The multi-directional and interlaced arc-shaped telescopic arms and telescopic backs between the joints enable uninterrupted transmission of driving force, change the vertical angle of the joint into multi-directional small intersection angles, and effectively disperse the space between the wheel and the expansion joint The impact force greatly reduces the vibration and noise generated by the impact force, and can make the vertical and horizontal telescopic displacement flexible and completely eliminate the rattling noise trouble.
.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.
