LINKING UNITS TO CONNECT THE FLOATING BRIDGE UNITS AND THE FLOATING BRIDGE USING THE LINKING UNITS

摘要

PURPOSE: A prefabricated pontoon bridge and a refraction connecting unit for the same are provided to mount a branched point or reflected point of the refraction connecting units. CONSTITUTION: A refraction connecting unit for a prefabricated pontoon bridge comprises a floating body(110), a backing plate(120), an upper plate(130), a rotary plate(140), an upper plate connecting bracket(300), an assembly unit and a rotational friction reducing unit. The floating body keeps the refraction connecting unit on the water. The backing plate is disc shape and fixed on the upper plate. The upper plate is the disc shape corresponding to the shape of the backing plate and is mounted on the upper plate at regular intervals. The rotary shaft is located between the backing plate and the upper plate and has a connecting frame(142). The upper plate connecting bracket is mounted at an end of the connecting frame. The assembly unit keeps the backing plate, the rotary plate and the upper plate to be piled. The rotational friction reducing unit is mounted between the backing plate and the rotary plate.
