Mechanical couplings for pontoons and similar floatable units

摘要

A mechanical coupling for connecting together two buoyant members, such as pontoons, to make a buoyant structure. The mechanical coupling comprises vertical grooves in the pontoons. A pair of spaced apart plates partially cover the edge of the grooves. A key member in the shape of an I-beam fits with its web between the plates of a pair of pontoons so that its flanges hold the two pontoons together. Wedge shaped members attached to the I-beam and to the plates further act to wedge and lock the pontoons together as a unit.
