A concrete module having a buoyant center core with a light weight concrete outer shell. The modules have lengthwise and width wise passages on non-common planes. The modules are connected with rods, cables or other interconnecting methods through the passages. The sides of the modules may be curved to allow the modules to fit securely together along the vertical corners in a straight line without bowing or bending. The top of the module may be constructed with reinforcing ribs for strength. The size of the modules are designed to be transported using standard hauling trucks and moved with skid loaders or fork lifts. The modules have common sizes and connecting passages between modules to make uniform modules to allow custom designed docks and other floating structures to be configured. A variety of brackets are provided for attaching other structures to the modules making up the floating structure.
A floating module and fastening system for interconnecting a row of modules while allowing relative movement of the modules resulting from wave action. The present invention provides a system for interconnecting floating structures to form breakwaters and other integrated floating structures. The interconnection system includes one or more cables or other securing lines extending longitudinally through a row of floating structures and fastened at the ends of the row. Two or more socket members, through which the cables pass, are secured in and project outwardly from each end wall of the floating structures. Each of the socket members defines a recess, which extends into the end walls of the floating structures. Opposed socket members projecting from adjacent floating structures are sized so that an end of a first of the socket members fits within an opposed end of a second of the socket members. A resilient member or cushion having a shape generally corresponding to the shape of the recesses in the opposed socket members may be received within adjacent recesses of overlapping first and second socket members.
