The closed cast steel bridge expansion joint device series is currently a new product in the expansion joint industry. It is made of high-quality alloy steel precision casting (or profile steel). It is designed with reinforced rib support under the telescopic arm to ensure that the telescopic arm does not break or bend. Deformation, truly ensuring driving safety and comfort. The gap filler adopts the company's invention patent: nano waterproof sealing material. The gap filler does not require any adhesive and is firmly bonded with the steel structure telescopic bodies on both sides to form a elastic body between the gaps. The overall structure prevents the deformation of expansion joint steel components, makes no noise when passing the vehicle, has long service life, good elasticity, anti-fatigue, anti-water seepage, anti-dust ingress, good sealing performance, and ensures no noise pollution in the environment and no maintenance for life. * The multi-directionality of the arc-shaped telescopic arm and telescopic back between the joints makes the vertical angle between the driving direction and the joint direction change into a multi-directional small intersection angle, effectively dispersing the impact force between the wheel and the expansion joint, and reducing the impact caused by the impact. The vibration and noise are reduced, making the beam flexible to expand and contract
*The telescopic arm of the telescopic device is multi-directional in design, which is suitable for telescopic deformation of bridges with various intersection angles. It can be customized and produced according to the design of bridges with different intersection angles
* It reduces the later maintenance costs of the bridge project, extends the service life of the bridge, and improves economic benefits!
