Description
It is primarily composed of components such as double S-shaped panel steel sections, vertical plates, stainless steel U-shaped drainage channels, anchor plates, and anchor rings.
Performance Features
◆ Full steel structure ensures long service life: The expansion joint features an all-steel design, eliminating rubber components to prevent rubber aging issues. This results in durable performance, exceptional longevity, and the ability to maintain full operational life.
◆ Excellent impact resistance: Utilizing dual S-shaped steel, the wheels pass through the expansion joint at different times, creating an oblique motion between the wheels and the joint. This design minimizes the direct impact of vehicle loads on the expansion joint (reducing impact force by up to 50%), thereby enhancing the product’s structural durability and improving driving comfort.
◆ Excellent Noise Reduction Performance: Measured tests show that, compared to straight-seam expansion joints, the full-lifespan impact-resistant and noise-reducing expansion joint reduces noise by approximately 10 decibels, delivering outstanding noise reduction results.
◆ Sound Barrier & Absorption: The design incorporates a soundproof stainless steel drainage channel at the bottom, effectively blocking noise from traveling downward and preventing the concentration of sound effects.
◆ Low Cost: Simple construction, no vulnerable parts, resulting in low maintenance and upkeep costs during the service period;
◆ Easy-to-Control Installation Accuracy: This method can address defects left behind by bridge construction teams that failed to follow standard procedures (such as irregular or unevenly deep and shallow grooves), making precision easier to manage.
◆ Beautiful in design: Combining curves with straight lines, blending strength with flexibility, the double-S shape resembles auspicious clouds—graceful, melodious, and imbued with positive symbolism, perfectly aligning with traditional Chinese cultural motifs.
