STs joint type
STs’s Modular Joints are designed as multiple or single support bar joints systems depending on the required range of movement and the intended application. They are designed to accommodate structural movements through on arrangement of adjacent connecting seals that have a self regulating gap system designed to ensure that all seals open equally. The joints are made up of an arrangement of edge and center beams that run perpendicular to the bridge’s longitudinal axis and are interspersed with neoprene seals. The center beams in turn slide on support beams that are arranged to move along one or both edges. The support beams are designed to allow rotational and sliding movements.
Sts’s modular joints significantly reduce road surface traffic noise and vibration to a minumum and the design approach also results in a continuous water tight connection at both minimum and maximum opening apertures, very durable fatigue free connections and maintenance free components.
