The arc-shaped butt-type bridge expansion joint is made up of two identical butt-type cast steel bridge expansion joint adjustment device components. The components are filled with high elastomer. The said butt-type cast steel bridge expansion joint The components of the adjustment device include: a telescopic table, an arc-shaped bar-shaped or toothed telescopic arm at the top of the telescopic table, a pedestal on the outside of the bottom of the telescopic table, a connecting rod in the middle of the outside of the telescopic table for connecting the embedded steel bars, and convenient Bolt holes for connection fixation. It is characterized in that: the telescopic platform of the component is the main component of the plug-in cast steel bridge expansion joint adjustment device that is fixedly connected with arc-shaped bar-shaped or tooth-shaped telescopic arms, pedestals, and connecting rods, and the plane is a curved vertical structure. The arc-shaped bar-shaped or tooth-shaped telescopic arm of the component, the telescopic platform, and the pedestal on the outside of the bottom of the telescopic platform form a font structure. Insert the inner depression of the expansion table of another component, and fill the gap with polymer elastomer to form a complete plug-in cast steel bridge expansion joint adjustment device. Main features:
. The multi-directional and interlaced arc-shaped telescopic arms and telescopic backs between the seams enable the transmission of driving force to be uninterrupted and change the vertical angle in the seam direction into multi-directional small intersection angles. It effectively disperses the impact force between the wheel and the expansion joint, greatly reduces the vibration and noise caused by the impact force, and enables flexible vertical and horizontal expansion and contraction displacement to completely eliminate the rattling noise trouble.
.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::\~\~\~\\\
