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 on-site formless molding of integral, unitary structures having complex shapes and junctions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
358 words
An integral intersecting concrete wall structure having a base wall and a side wall, wherein said base wall comprises: at least one bottom layer of open wire mesh; a plurality of longitudinally spaced reinforcing bars located above said bottom layer of open wire mesh; a plurality of laterally spaced reinforcing bars located above said longitudinally spaced reinforcing bars; a second plurality of longitudinally spaced reinforcing bars located above said laterally spaced reinforcing bars; at least one top layer of open wire mesh located above said second plurality of longitudinally spaced reinforcing bars; a concrete binder material surrounding substantially all of said longitudinally and laterally spaced reinforcing bars and forming top and bottom base wall surfaces, said bottom surface being located below said bottom layer of open wire mesh and said top wall surface being located above said top layer of open wire mesh; at least one base intersection beam located within said concrete binder such that a top portion of said intersection beam projects above said top wall surface; and wherein said side wall comprises: at least one outside layer of open wire mesh, said mesh parallel to and overlapping the outside surface of the projecting portion of said base intersection beam of said base wall; at least one inside layer of dense screen material parallel to said outside layer of open welded wire mesh and overlapping the inside surface of a portion of said base intersection beam; a plurality of side wall reinforcing bars spaced along the length of said intersection beam and structurally attached to the projecting portion of said base intersection beam, which plurality of side wall reinforcing bars lies between said outside layer of open wire mesh and said inside layer of dense screen material that are at an angle to said base wall; and a concrete binder material surroundings substantially all of said side wall reinforcing bars and forming inside and outside wall surfaces that are at an angle to said base wall, said inside surface being located inside of said inside layer of dense screen material and said outside wall surface being located outside of said outside layer of open wire mesh.
Claim 2
Dependent Claim
358 words
An integral intersecting concrete wall structure having a base wall and a side wall, wherein said base wall comprises: at least one bottom layer of open wire mesh; a plurality of longitudinally spaced reinforcing bars located above said bottom layer of open wire mesh; a plurality of laterally spaced reinforcing bars located above said longitudinally spaced reinforcing bars; a second plurality of longitudinally spaced reinforcing bars located above said laterally spaced reinforcing bars; at least one top layer of open wire mesh located above said second plurality of longitudinally spaced reinforcing bars; a concrete binder material surrounding substantially all of said longitudinally and laterally spaced reinforcing bars and forming top and bottom base wall surfaces, said bottom surface being located below said bottom layer of open wire mesh and said top wall surface being located above said top layer of open wire mesh; at least one base intersection beam located within said concrete binder such that a top portion of said intersection beam projects above said top wall surface; and wherein said side wall comprises: at least one outside layer of open wire mesh, said mesh parallel to and overlapping the outside surface of the projecting portion of said base intersection beam of said base wall; at least one inside layer of dense screen material parallel to said outside layer of open welded wire mesh and overlapping the inside surface of a portion of said base intersection beam; a plurality of side wall reinforcing bars spaced along the length of said intersection beam and structurally attached to the projecting portion of said base intersection beam, which plurality of side wall reinforcing bars lies between said outside layer of open wire mesh and said inside layer of dense screen material that are at an angle to said base wall; and a concrete binder material surroundings substantially all of said side wall reinforcing bars and forming inside and outside wall surfaces that are at an angle to said base wall, said inside surface being located inside of said inside layer of dense screen material and said outside wall surface being located outside of said outside layer of open wire mesh.
Claim 3
Dependent Claim
66 words
The integral intersecting concrete wall structure of claim 20 wherein Said intersection beam comprises: a plurality of closely spaced reinforcing bars lying approximately mutually parallel, and a plurality of short reinforcing bars spaced along one of said plurality of closely spaced reinforcing bars and structurally attached thereto at approximately right angles, which plurality of short reinforcing bars has a portion projecting above said top wall surface.
Claim 4
Dependent Claim
60 words
The integral intersecting concrete wall structure of claim 20 wherein said intersection beam comprises a structural beam having an upper and lower cap and a web therebetween, wherein said lower cap and a portion of said web are located within said base wall and the upper cap and a top portion of said web projects above said top wall surface.
Claim 5
Dependent Claim
136 words
The integral intersecting concrete wall structure of claim 20 having additionally a ceiling wall comprising: at least one bottom layer of dense screen material; at least one upper layer of open wire mesh; at least one ceiling intersection beam structurally secured to the upper ends of said side wall reinforcing bars; a plurality of ceiling reinforcing bars spaced along said ceiling intersection beam in intersecting relationship and laying between said bottom layer of dense screen material and upper layer of open wire mesh; and a concrete binder material surrounding substantially all of said ceiling reinforcing bars and a top portion of said ceiling intersection beam and forming top and bottom ceiling wall surfaces, said bottom surface being located below said dense screen material and said top ceiling wall surface being located above said open wire mesh.
Claim 6
Dependent Claim
40 words
The intersecting concrete wall structure of claim 23 wherein: a layer of said open wire mesh has openings of approximately 1 by one-half inch; and a layer of said dense screen material has openings of approximately one-fourth by three-eigths inch.
