The "DIA Free Joint" is an expansion joint for bridges that excels in durability and water-tightness, and is easy to install due to its simple structure and lightweight design. The surface shape is "tooth-shaped," while the back shape is "linear," allowing concrete to be filled up to the edge of the deck slab, further enhancing durability by integrating with the deck slab. In addition to enhancing water-tightness with a male-female structure at the rubber ends, the adhesive surface between the steel plate and rubber has been increased to prevent "rubber peeling," achieving a longer lifespan. 【Features】 ■ Excellent durability ■ Difficult for rubber to peel off ■ Ensures water-tightness ■ Lightweight with a simple structure ■ Good workability *For more details, please request materials or view the PDF data from the download section.
