Abstract

Abstract A fiber-cement/plywood surface and method of providing a preformed surface material for flooring, decking, walkways and roadways, more particularly for use with marine dock structures. The method includes applying a coating of a catalized resin material over one surface of a sheet of plywood substructure so as to seal the substructure as the resin hardens, and also coating one surface of a fiber-cement sheet with a catalized resin material and allowing it to harden. A bonding agent, which comprises a catalized resin material mixed with a thickening agent such as mill fibers or finely chopped fiberglass strands, is applied between the two facing resin surfaces of the respective plywood sheet and the fiber-cement sheet, whereby the two sheets are bonded together so as to form a single, somewhat-resilient, weatherproof and wear-resistant structure or panel. An alternative arrangement is also provided wherein the substructure is a thick plastic foam core encased in a fiberglass and polyester resin.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 97 words
A method of forming a walking-surface panel for floating docks and the like, comprising the steps of: providing a sheet of fiber-cement which defines the walking surface; coating one surface of said fiber-cement sheet with a catalized resin material to seal said surface; providing a sheet of plywood having a size substantially the same as that of said fiber-cement sheet; coating one surface of said plywood sheet with a catalized resin material to seal said surface; and bonding said fiber-cement sheet to said plywood sheet, wherein a bonding material is interposed between said coatings of said sheets.
Claim 2
Independent Claim 97 words
A method of forming a walking-surface panel for floating docks and the like, comprising the steps of: providing a sheet of fiber-cement which defines the walking surface; coating one surface of said fiber-cement sheet with a catalized resin material to seal said surface; providing a sheet of plywood having a size substantially the same as that of said fiber-cement sheet; coating one surface of said plywood sheet with a catalized resin material to seal said surface; and bonding said fiber-cement sheet to said plywood sheet, wherein a bonding material is interposed between said coatings of said sheets.
Claim 3
Dependent Claim 24 words
A method as recited in claim 1 wherein said fiber-cement sheet is composed by combining cement, crushed limestone, volcanic ash, and a fibrous material.
Claim 4
Dependent Claim 20 words
A method as recited in claim 2, wherein said bonding material interposed between said sheets comprises a catalized epoxy resin.
Claim 5
Dependent Claim 25 words
A method as recited in claim 2 wherein said bonding material interposed between said sheets comprises a catalized polyester resin mixed with a thickening agent.
Claim 6
Dependent Claim 35 words
A method as recited in claim 4, wherein said plywood sheet is formed having a tongue member along one abutting transverse edge thereof, and a matching groove along the oppositely disposed abutting transverse edge thereof.
Claim 7
Dependent Claim 25 words
A method as recited in claim 2, wherein said fiber-cement sheet comprises 36% cement; 30% crushed limestone; 20% volcanic ash; and 14% silky fibrous material.
Claim 8
Dependent Claim 19 words
A method as recited in claim 6 wherein said fiber-cement sheet is formed having 1/4 of an inch thickness.
Claim 9
Dependent Claim 25 words
A method as recited in claim 7, wherein said plywood sheet is formed having a thickness of between 3/4 of an inch and 11/2 inch.
Claim 10
Dependent Claim 17 words
A method as recited in claim 7, wherein said plywood sheet is formed having 11/8 inch thickness.
