Utility distribution system for marine floats

Claim 2

A marine float, comprising a concrete casing surrounding a buoyant core, said casing having a bottom, two opposed end walls, two opposed side walls connecting opposite edges of said end walls and a generally planar deck extending between the upper edges of said end and side walls, said deck having formed therein a longitudinal utility trench having a bottom connecting the lower edges of two trench walls, said trench extending between said end walls to facilitate the routing of utility conduits along said float, said deck also having formed therein a transverse utility passage extending generally perpendicularly from said longitudinal utility trench and opening upwardly in said deck adjacent one side thereof to facilitate the routing of utility conduits to utility outlets mounted adjacent the side walls of the casing, said casing further including a plurality of spaced-apart, generally parallel tie rods extending between said side walls beneath the bottom of said trench, and respective fasteners secured to the ends of said tie rods to tension said tie rods, thereby forcing the side walls of said casing toward each other to compressively load said casing.

Claim 3

The marine float of claim 1, wherein the ends of said tie rods project through elongated wales extending along the upper edge of each side wall with said fasteners being secured to said tie rods along the outer surfaces of said wales thereby securing said wales to said float.

Claim 4

The marine float of claim 1, wherein said casing further includes a plurality of parallel spaced-apart ribs projecting downwardly from said deck and integrally formed therewith between the side walls of said casing.

Claim 5

The marine float of claim 3, wherein said tie rods are embedded in respective of said ribs such that said ribs are compressively loaded by said tie rods.

Claim 6

The marine float of claim 1, wherein a tubular conduit is embedded in said deck between said trench and a side wall of said casing to facilitate the routing of said utility conduits from said trench to utility outlets mounted adjacent a side wall of said float.

Claim 7

The marine float of claim 1, wherein two of said utility trenches are formed in said deck along and closely adjacent said side walls with said tie rods extending between said side walls beneath both of said utility trenches.

Claim 8

The marine float of claim 6, further including a utility passage extending from each of said trenches to an opening formed in the upper surface of said deck toward the respective adjacent side walls.

Claim 9

The marine float of claim 7, further including a utility outlet projecting upwardly from said opening and receiving a utility conduit from said trench through said passage.

Claim 10

The marine float of claim 7, wherein said passages are formed by tubular conduit extending from said utility trench to the upper surfaces of said deck adjacent said side wall.

Claim 11

A marine float comprising: a buoyant core generally having the shape of a rectangular prismatoid; a concrete casing surrounding said core, said casing having a bottom, a pair of spaced-apart end walls, a pair of spaced-apart side walls extending longitudinally between corresponding sides of said end walls and a deck connecting the upper edges of said end walls and said side walls, said deck having formed therein an elongated utility trench extending longitudinally between said end walls, and a plurality of spaced-apart, generally parallel ribs extending transversely between said side walls, said ribs projecting downwardly from said deck beneath said trench such that the lower portions of said ribs extend continuously from one side wall to the other; an elongated wale extending along the upper edge of each side wall; transversely positioned, respective tie rods extending transversely across said casing beneath said trench, with the ends of the said tie rods projecting through the side walls of said casing and said wales, all of said tie rods being embedded in respective ribs so that said ribs brace the side walls of said casing against the tensional forces of said tie rods; respective fastener means mounted on said ends of said tie rods for tensioning said tie rods, thereby securing said wales to said side walls and compressionally loading said casing; and a passage extending between said utility trench and an opening formed in the upper surface of said deck adjacent one of said side walls for routing utility conduits to a utility outlet mounted on said deck adjacent the opening on the upper surface thereof.

Claim 12

A marine float comprising: a buoyant core generally having the shape of a rectangular prismatoid; a concrete casing surrounding said core, said casing having a bottom, a pair of spaced-apart end walls, a pair of spaced-apart side walls extending longitudinally between corresponding sides of said end walls and a deck connecting the upper edges of said end walls and said side walls, said deck having formed therein an elongated utility trench extending longitudinally between said end walls, and a plurality of spaced-apart, generally parallel ribs extending transversely between said side walls, said ribs projecting downwardly from said deck beneath said trench such that the lower portions of said ribs extend continuously from one side wall to the other; an elongated wale extending along the upper edge of each side wall; transversely positioned, respective tie rods extending transversely across said casing beneath said trench, with the ends of the said tie rods projecting through the side walls of said casing and said wales, all of said tie rods being embedded in respective ribs so that said ribs brace the side walls of said casing against the tensional forces of said tie rods; respective fastener means mounted on said ends of said tie rods for tensioning said tie rods, thereby securing said wales to said side walls and compressionally loading said casing; and a passage extending between said utility trench and an opening formed in the upper surface of said deck adjacent one of said side walls for routing utility conduits to a utility outlet mounted on said deck adjacent the opening on the upper surface thereof.

Claim 13

The marine float of claim 10, wherein said passages are formed by tubular conduits embedded in said deck.

Claim 14

The marine float of claim 10, wherein said passages are formed by transverse trenches formed in said deck and extending between said longitudinal trench and one of said side walls.
