Abstract
Abstract A floating wharf structure wherein interconnected walkways are provided spaced from the top surfaces of supporting pontoons. Each of the walkways comprises a flat sheet of wire mesh screen and spacing means are defined by reinforcing bars disposed downwardly from the sheet. The screen and bars are encased in concrete shaped to define the walkway and integral spacing means. The walkways are interconnected by flanges extending downwardly from the walkways to contralaterally flank underlying pontoons. Each pontoon comprises walls of concrete defining a chamber and polymer foam filling the chamber.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
57 words
A floating wharf structure, comprising: a plurality of pontoons; and a plurality of interconnected walkways overlying said pontoons, each walkway integrally formed with concrete support members lengthwise under each side of said walkway and extending downwardly therefrom to about the top surface of an underlying pontoon whereby to support said walkway spaced from said pontoon top surface.
Claim 2
Dependent Claim
57 words
A floating wharf structure, comprising: a plurality of pontoons; and a plurality of interconnected walkways overlying said pontoons, each walkway integrally formed with concrete support members lengthwise under each side of said walkway and extending downwardly therefrom to about the top surface of an underlying pontoon whereby to support said walkway spaced from said pontoon top surface.
Claim 3
Dependent Claim
42 words
The structure of claim 1 including an additional support member of concrete formed integrally with said walkway lengthwise and substantially centrally thereof to abut the top surface of said underlying pontoon whereby to support said walkway spaced from said pontoon top surface.
Claim 4
Dependent Claim
34 words
The structure of claim 1 wherein said interconnecting means comprises flanges extending downwardly from said walkway to contralaterally flank an underlying pontoon for limiting lateral movement of said flanked pontoon relative to said walkway.
Claim 5
Dependent Claim
50 words
The structure of claim 1 wherein each of said walkways comprises a flat sheet of wire mesh screen and said support members are formed about reinforcement bars disposed downwardly from said sheet, said screen and bars being encased in concrete shaped to define said walkway and said integral support members.
Claim 6
Dependent Claim
23 words
The structure of claim 1 wherein each of said pontoons comprises walls of concrete defining a chamber and rigid foam filling said chamber.
Claim 7
Dependent Claim
78 words
A walkway unit, comprising: a sheet of wire mesh screen; reinforcement bars spaced downwardly from the longitudinal sides of said sheet and extending lengthwise therewith; and concrete encasing said screen and bars and shaped to define a walkway and integral elongate side members, respectively, said side members each extending substantially a predetermined distance downwardly from said walkway and having little horizontal extent relative to the horizontal extent of said walkway whereby to define open spaces between support members.
Claim 8
Dependent Claim
78 words
A walkway unit, comprising: a sheet of wire mesh screen; reinforcement bars spaced downwardly from the longitudinal sides of said sheet and extending lengthwise therewith; and concrete encasing said screen and bars and shaped to define a walkway and integral elongate side members, respectively, said side members each extending substantially a predetermined distance downwardly from said walkway and having little horizontal extent relative to the horizontal extent of said walkway whereby to define open spaces between support members.
Claim 9
Dependent Claim
68 words
The unit of claim 6 including at least one reinforcement bar disposed lengthwise and substantially centrally of said sheet and spaced downwardly therefrom, said concrete encasing said bar and shaped thereat to define an integral elongate central member extending substantially said predetermined distance downwardly from said walkway and having little horizontal extent relative to the horizontal extent of said walkway whereby to define open spaces between support members.
Claim 10
Dependent Claim
22 words
The unit of claim 6 including a plurality of fastening members spaced apart along the sides thereof and embedded in said concrete.
Claim 11
Dependent Claim
101 words
A floating wharf structure, comprising: a first walkway; a second walkway laterally of said first walkway; a corner section between an edge of said first walkway and an edge of said second walkway, said corner section having an outer edge defining with said first walkway an acute angle facing said second walkway, said corner section outer edge defining with said second walkway an acute angle facing said first walkway; and a one-piece bracket connecting in a single plane the top surface of said corner section outer edge to the top surface of at least one of said first and second walkways.
Claim 12
Dependent Claim
101 words
A floating wharf structure, comprising: a first walkway; a second walkway laterally of said first walkway; a corner section between an edge of said first walkway and an edge of said second walkway, said corner section having an outer edge defining with said first walkway an acute angle facing said second walkway, said corner section outer edge defining with said second walkway an acute angle facing said first walkway; and a one-piece bracket connecting in a single plane the top surface of said corner section outer edge to the top surface of at least one of said first and second walkways.
