Abstract
Abstract The specification discloses foam insulation board for use in plaza deck construction, the upper and lower surfaces of which contain drainage channels. To avoid problems of easy breakage, especially of the kind associated with larger foam insulation boards having upper and lower drainage channels, the present invention discloses orienting the lower surface drainage channels 90° with respect to the upper surface drainage channels, such that the two opposing surfaces of channels are perpendicular to each other.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
103 words
Insulation panel, for use in constructing horizontal parking structures, plaza decks, and the like, comprising: a panel of foam material having first and second sets of generally parallel drainage channels located in opposing top and bottom surfaces of said panel, respectively, said first set channels on said top surface being oriented generally perpendicular to said second set drainage channels on said bottom surface, said panel being free of generally parallel top and bottom channels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion rather than running the full length or full width of said panel.
Claim 2
Dependent Claim
103 words
Insulation panel, for use in constructing horizontal parking structures, plaza decks, and the like, comprising: a panel of foam material having first and second sets of generally parallel drainage channels located in opposing top and bottom surfaces of said panel, respectively, said first set channels on said top surface being oriented generally perpendicular to said second set drainage channels on said bottom surface, said panel being free of generally parallel top and bottom channels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion rather than running the full length or full width of said panel.
Claim 3
Dependent Claim
39 words
The insulation panel of claim 1, wherein said channels on said upper surface and said channels on said bottom surface each have a width of around one-sixteenth inch to one-inch and a depth of approximately one-tenth inch to one-inch.
Claim 4
Dependent Claim
27 words
The insulation panel of claim 2, said panel having variable dimensions of around one-quarter to four feet long and anywhere from four feet to twenty feet wide.
Claim 5
Dependent Claim
14 words
The insulation panel of claim 3, wherein said panel is comprised of polystyrene foam.
Claim 6
Dependent Claim
15 words
The insulation panel of claim 4, wherein said polystyrene foam is of the closed-cell variety.
Claim 7
Dependent Claim
17 words
The insulation panel of claim 4 including a layer of porous fabric over said first set channels.
Claim 8
Dependent Claim
17 words
The insulation panel of claim 2 including a layer of porous fabric over said first set channels.
Claim 9
Dependent Claim
17 words
The insulation panel of claim 1 including a layer of porous fabric over said first set channels.
Claim 10
Dependent Claim
14 words
The insulation panel of claim 1, wherein said panel is comprised of polystyrene foam.
Claim 11
Dependent Claim
27 words
The insulation panel of claim 1, said panel having variable dimensions of around one-quarter to four feet long and anywhere from four feet to twenty feet wide.
Claim 12
Independent Claim
137 words
A method for constructing a plaza deck/parking structure comprising: providing a plurality of panels of foam plastic insulation having first and second sets of generally parallel drainage chapels located in opposing top and bottom surfaces of said panel, respectively, said first set chapels on said top surface being oriented generally perpendicular to said second set drainage chapels on said bottom surface, said panel being free of generally parallel top and bottom chapels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion, rather than running the full length of full width of said panel; providing a base deck: placing a waterproof membrane on top of said base deck; placing said plurality of foam plastic panels on top of said waterproof membrane, and installing a concrete wear layer over said panels.
Claim 13
Independent Claim
137 words
A method for constructing a plaza deck/parking structure comprising: providing a plurality of panels of foam plastic insulation having first and second sets of generally parallel drainage chapels located in opposing top and bottom surfaces of said panel, respectively, said first set chapels on said top surface being oriented generally perpendicular to said second set drainage chapels on said bottom surface, said panel being free of generally parallel top and bottom chapels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion, rather than running the full length of full width of said panel; providing a base deck: placing a waterproof membrane on top of said base deck; placing said plurality of foam plastic panels on top of said waterproof membrane, and installing a concrete wear layer over said panels.
Claim 14
Dependent Claim
42 words
The method of claim 11, wherein said channels on said upper surface and said channels on said bottom surface are each provided with a width of around 1.16 inch to 1 inch and a depth of approximately 1.10 inch to 1 inch.
Claim 15
Dependent Claim
28 words
The method of claim 12 in which said panels are provided in dimensions of from 1/4 to 4 feet long and from 4 feet to 20 feet wide.
Claim 16
Dependent Claim
13 words
The method of claim 13 wherein said panels are made of polystyrene foam.
Claim 17
Dependent Claim
15 words
The method of claim 14 wherein said polystyrene foam is of the closed cell variety.
Claim 18
Dependent Claim
33 words
The method of claim 14 which includes placing a layer of porous fabric over said first set channels and affixing said layer to the top of said ribs on each of said panels.
Claim 19
Dependent Claim
33 words
The method of claim 12 which includes placing a layer of porous fabric over said first set channels and affixing said layer to the top of said ribs on each of said panels.
Claim 20
Dependent Claim
33 words
The method of claim 11 which includes placing a layer of porous fabric over said first set channels and affixing said layer to the top of said ribs on each of said panels.
Claim 21
Dependent Claim
13 words
The method of claim 11 wherein said panels are made of polystyrene foam.
Claim 22
Dependent Claim
28 words
The method of claim 11 in which said panels are provided in dimensions of from 1/4 to 4 feet long and from 4 feet to 20 feet wide.
