This disclosure relates to boat docks and, more particularly, to structures that accommodate marina construction utilities.
In marina construction, encapsulated flotation is only used to float the dock, not to support the utilities of the dock. The utilities are typically run through the structure or frame of the dock. When the dock is damaged and a metal frame or wooden structural member needs to be replaced, all electrical utilities have to be pulled from the nearest termination. The frame is then replaced and the electrical and water utilities are reinstalled.
In scenarios where a “box” frame is used, electrical utilities when designed with single insulated wired are installed within PVC conduit which is ran through interior voids of the frame. When docks are installed with jacketed electrical cable, the cable is clamped to the frame of the dock to prevent wear on the cable, and laid on top of the flotation when metal is not present. Water and wastewater utilities are always installed through PVC and run through the frame of the dock.
In situations where the dock is made of a wooden structure, the wood is cut with holes that match the size of the utility cable and PVC size required. This creates a weaker dock and adds time to the installation. The cables are placed on top of the floatation when a wooden structure is not present.
Often times the electrical cable rubs on the metal or wood frame of the dock, eventually leading to an exposed electrical cable. This not only creates shorts in the wire that lead to potential fire hazard, it exposes people to electrical shock and potential death when the electrical current disperses through the water. Furthermore, damage to the electrical cable occurs when the dock is damaged as a result of storms. For example, a frame can cut the electrical cable when the frame is warped, sheared, and mis shaped because of the storm.
Embodiments of a modular float design allows marina utilities to run under the main frame of the dock while at the same time adding strength and durability to the float. Utility trays or troughs are molded directly into the float where previously the float had been flat along its upper surface. These troughs simplify and separate the installation of all electric, potable water, and non-potable water. At the same time the troughs allow the dock to be modified without disrupting the marina. Because the utilities would avoid the interior voids of the frame, safety is increased, installation time is decreased, and maintenance costs are lowered.
By installing the utilities below the main (galvanized metal) frame, there is less risk of the frame causing damage to an electrical cable. The cable's insulation no longer contacts or rubs against the structure of the dock, nor is it exposed to the frame during storms. Additionally, the dock no longer needs to be drilled with holes to install any utilities. With the absence of these holes there is added strength to the dock. Last, maintaining the dock becomes a much easier process.
Referring to the drawings, an encapsulated modular float or flotation section 10 arranged for connection to a main frame M of a dock—and to other sections 10 by way of sockets or connectors 19—includes one or more spaced apart utility trays or troughs 15 that are molded into a top end 17 of the section 10 and extend an entire width (
In embodiments, a plurality of spaced apart sockets 19 are located along a periphery 14 of the modular flotation section 10, each socket 19 of the plurality oriented perpendicular to the top surface 17 of the modular flotation section 10, an uppermost end 20 of each socket 19 extending to the top surface 17 of the modular flotation section 10. Located at the uppermost end 20 of a respective socket 19 is a flange 39 oriented parallel to the top surface 17 of the modular flotation section 10, each flange 39 including an open-ended slot 41 open toward the periphery 14 of the modular flotation section 10 and sized to receive a fastener for attachment to a portion of the main frame M. The flange 39 is shaped complementary to the socket 19. The sockets 19 and flanges 39 may be semi-circular shaped.
The troughs 15 are generally U-shaped in cross-section (but can be any shape preferable) with an open upper end 25, a closed bottom end or floor 27, and sidewalls 29 forming a right angle with the floor 27. In embodiments, electric conduit or cables can be run along one of the troughs 15 and potable and non-potable water pipes or lines can be run along the other trough 15. The cables or lines rest on the closed bottom end or floor 27 of the trough 15, between sidewalls 29. In other embodiments, the cables or lines are suspended from the frame by hangars 31. The open ends 31 of the trough 15 permit the cables or lines to run from one flotation section 10 to the next flotation section 10.
The depth 21 and width 23 of the trough 15 are sized appropriate for the application, with the depth 21 being less than an overall height “h” of the modular flotation section 10 and the width 23 being less than an overall width “w” of the section 10. The depth 21 may vary from section 10 to section 10 (as may the width 23 or both width and depth). In some embodiments, trough 15 has a depth “d1” and another trough 15 a different depth “d2.” The depth 21 is such that none of the cables or utility lines when laid in the trough 15 contact the main frame of the dock. The troughs 15 do not significantly affect the flotation performance of the section 10.
While embodiments of an encapsulated utility float have been described in detail, modifications may be made in the details of construction or method of use without departing from the scope of this disclosure or the following claims. The claims encompass the full range of equivalents to which each recited element or step is entitled.
This application claims priority to U.S. Prov. Pat. Appl. Ser. No. 62/417,392, filed Nov. 4, 2016, the contents of which are incorporated by reference.
