Abstract
Abstract A large buoy construction of relatively thin wall composite material, which walls are integrally formed and interconnected by a reinforcing matrix frame comprising reinforcing members sandwiched between layers of screens, to which the cement-type material can be applied by use of power equipment in a rapid application and thorough penetration into the matrix to accomplish onsite formless molding of integral, unitary structures having complex shapes and junctions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
37 words
The method as claimed in claim 1 including the step of, overlapping adjacent edges of adjacent layers of said screen material at intersections of said first reinforcing bars and said reinforcing member, and said second reinforcing bars.
Claim 2
Dependent Claim
150 words
The method as claimed in claim 1 including the steps of, rigidly securing a second reinforcing member to the upper ends of said plurality of second spaced reinforcing bars in said wall frame, laying a plurality of third spaced reinforcing bars on said second reinforcing member in intersecting relationship, placing third layers of relatively open screen material on the upper side of said third reinforcing bars and second layers of relatively dense screen material on the bottom side of said third reinforcing bars, projecting a cement mixture in a steam through said third layer of relatively open screen material and against said second layers of relatively dense screen material, projecting said cement mixture in a pattern in sufficient volume to fill the spaces in said third layers of relatively open screen material and said second layers of relatively dense screen material and the volume therebetween, and curing said cement mixture.
Claim 3
Dependent Claim
43 words
The method as claimed in claim 1 in which, said reinforcing member comprises a beam with holes therethrough along the length thereof of for receiving ones of said first reinforcing bars, and others of said first reinforcing bars aRe positioned below said beam.
Claim 4
Dependent Claim
54 words
The method as claimed in claim 1 in which, said plurality of first spaced reinforcing bars comprises a matrix of spaced, intersecting reinforcing bars, and said reinforcing member comprises at least two aligned and adjacently positioned reinforcing bars with said second spaced reinforcing bars being rigidly secured to one of said two aligned bars.
