Abstract
A corrosion resistant prestressed float unit including a buoyant core encased within a polymeric coating, concrete encasing the core and polymeric coating, a corrosion resistant mesh to reinforce the concrete, and a plurality of corrosion resistant pretensioned fiber members extending the entire length of the unit.
Description
- This invention relates generally to prestressed concrete flotation structures. More particularly, this invention relates to floating prestressed concrete structures which are more corrosion resistant than conventional floating concrete structures.
- Prestressed concrete floatation structures are well known for use as docks, wharves, and the like. Such structures, such as described in U.S. Pat. No. 3,799,093 entitled FLOATING PRESTRESSED CONCRETE WHARF, include a buoyant material, such as expanded polystyrene, a layer of concrete surrounding the buoyant material, reinforcing wire mesh surrounding the buoyant material and located within the concrete layer, and pretensioned steel cables extending through the concrete to maintain it in compression. It has been observed that over time, particularly when the dock or other float structures are used in a saltwater environment, that the cables and wire reinforcing mesh may corrode and weaken the strength of the dock.
- With regard to the foregoing, the present invention is directed to corrosion resistant prestressed concrete float units.
- In a preferred embodiment, the units include a buoyant core encased within a polymeric coating, concrete encasing the core and polymeric coating, a corrosion resistant mesh to reinforce the concrete, and a plurality of corrosion resistant pretensioned fiber members extending the entire length of the unit.
- In another aspect, the invention relates to a dock system made by interconnecting a plurality of the float units. The units preferably include chaseways for receiving post tensioning members for interconnecting a plurality of the units to provide the dock system.
- Further features of preferred embodiments of the invention will become apparent by reference to the detailed description of preferred embodiments when considered in conjunction with the figures, which are not to scale, wherein like reference numbers, indicate like elements through the several views, and wherein,
-
FIG. 1 is a perspective view of a float system according to a preferred embodiment of the invention, partially cut away to show interior portions thereof. -
FIGS. 2A-2F show preferred cross-sectional geometries of float systems according to the invention. -
FIG. 3 shows a plurality of the float systems ofFIG. 1 arranged to provide a dock system according to a preferred embodiment of the invention. -
FIGS. 4A-4B show preferred inclusion of mooring members and the like on the float system. -
FIGS. 5A-5B show two examples of dock structures according to the invention. - With reference to the drawings, the invention relates to a corrosion resistant prestress concrete float system featuring one or more
floating units 10. Eachunit 10 preferably has a cross-section configuration as depicted inFIGS. 2A-2F , but may also be configured to have other cross-sections. A plurality of theunits 10 may be arranged as seen inFIG. 3 andFIGS. 5A-5B to provide a floating dock orwharf system 12. - Returning to
FIG. 1 , eachunit 10 is constructed so as to be relatively corrosion resistant when used in a marine environment. This is accomplished in a preferred embodiment by avoiding the use of components such as steel in the construction of theunits 10. - In a preferred embodiment, each
unit 10 preferably includes abuoyant core 14 encased within apolymeric coating 16,concrete 18 encasing thecore 14 andpolymeric coating 16, a corrosionresistant mesh 20 to reinforce theconcrete 18, and a plurality of corrosion resistantpretensioned fiber members 22 extending the entire length of theunit 10. Theunit 10 also preferably includes a plurality ofchaseways 24 for receiving post tensioningmembers 26 for interconnecting a plurality of theunits 10 in a desired manner. Theunit 10 floats in water, with the line W inFIG. 1 generally indicating the water level relative to theunit 10 during use. - The
core 14 is preferably provided by expanded polystyrene foam or polyurethane foam. Thepolymeric coating 16 which encases thecore 14 is preferably a polyethylene coating. Thecoating 16 is preferably roughened to facilitate bonding to theconcrete 18, and may be abraded or have appendages, corrugations or the like. Thecoating 16 inhibits moisture from contacting thecore 14 to avoid thecore 14 from becoming waterlogged and otherwise deteriorating from exposure to moisture, chemicals, and other substances which tend to deteriorate thecore 14. If desired, a vent may be provided between thecore 14 and the atmosphere to enable venting of gases that develop. This may be accomplished as by apolymeric tube 27 or the like located to pass from the core and through thecoating 16 andconcrete 18 to a surface of the concrete, such as a side near the top. The exposed end of the tube is preferably configured to inhibit passage of moisture or other matter back to the core. - The
concrete 18 is preferably a lightweight, regular weight, or polymer modified concrete material applied so as to surround thecore 14. The corrosionresistant mesh 20 provides reinforcement to strengthen theconcrete 18 against loading, environmental changes such as temperature changes, and the like. Themesh 20 is preferably made of carbon fiber, polymeric materials such as polyethylene, glass reinforced plastic, or like materials which are substantially resistant to corrosion in a marine environment and resistant to corrosion in an alkali-concrete environment. - The corrosion resistant
pretensioned fiber members 22 are preferably made of materials which are substantially resistant to corrosion in a marine environment and resistant to corrosion in an alkali-concrete environment, such as carbon fiber strands, kevlar/aramid fiber strands, plain or vinyl ester coated glass fiber strands, polymeric fiber strands, and the like. - The
chaseways 24 are preferably of extruded polyvinyl construction to provide chaseways that resist corrosion/deterioration in a marine/alkali-concrete environment. Thechaseways 24 may preferably be provided as by pvc piping. Thechaseways 24 receive the post tensioningmembers 26, which are preferably formed of similarly non-corrosive materials, most preferably carbon fibers or aramid fibers. Theunits 10 may preferably be strung on themembers 26 to provide a dock or other floating structure. - The
units 10 are made using a suitable mold and tensioning devices for pouring of the concrete. After the concrete is cured, thefiber members 22 are preferably trimmed to be flush with the exterior of theconcrete 18 or thepost tensioning member 26 or restraints therefor. An upper ordeck surface 28 of theconcrete 18 may be brushed during curing to provide anon-slip surface 31. - With reference to
FIGS. 4A-4B , the concrete may be configured to receive threadedinserts 30 for attachment ofmooring cleats 32, with theinsert 30 preferably being configured, as by including an aperture, for passage of thepretensioned fiber members 22 or other reinforcement. Likewise,rail member 34, such as a board, preferably having arubber bumper rail 36 adhered thereto, may be attached as bybolt 38 which cooperates with theinsert 30. Therail member 34 preferably includes an insert portion 39 so that thebolt 38 does not protrude. Also,elastomeric pads 40 are preferably adhered or otherwise secured to the exteriors of theunits 10 for padding between adjacent units. - With reference to
FIG. 5A , a plurality of theunits 10 are interconnected and extend from aboarding ramp 42 which extends from abulkhead 44. InFIG. 5B , afloating platform 46 is provided by a plurality of theunits 10 arranged side-by-side. In this regard, it is noted that theunits 10 may be of a variety of sizes and configurations and may be utilized withother units 10 or other structures to provide a wide variety of floating configurations. - The foregoing description of certain exemplary embodiments of the present invention has been provided for purposes of illustration only, and it is understood that numerous modifications or alterations may be made in and to the illustrated embodiments without departing from the spirit and scope of the invention as defined in the following claims.
