Doshin Modular Expansion Joint System is a mechanical device installed in between bridge decks. Its main function is to allow for smooth vehicular movement across expansion joint openings. This is achieved by employing the use of lamella beams which divides the expansion joint openings into smaller individual gaps. The lamella beams are connected by EPDM rubber that acts as a watertight seal that prevents debris and water from passing through bridge expansion joints openings and damaging the bridge deck and structures below.
Doshin Finger Expansion Joints are cantilevered or simply supported steel tooth expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths. The Joints are used to provide support to vehicles as they travel across bridge expansion joint openings. They create an effective seal at the joint opening, preventing water and deleterious materials from contacting the steel support girders and bearings below.
