Abstract
Abstract A prefabricated panel is disclosed which has high structural strength and simplifies the fabrication of buildings on site. The panels cooperate with structural grid type members to provide infill for the grid while, more importantly, significantly contributing to the overall structural stability of the building. The structural grid type members, in a preferred embodiment, are of a cement material and can be poured in place in cavities preformed in the panels. The panels can be prefabricated and, in a preferred embodiment, for interior and exterior finish materials are part of the panels.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
94 words
A building wall comprising a plurality of prefabricated interconnected panels where each panel provides infill and substantially contributes to structural stability of the building wall, each prefabricated panel comprising an exterior portion, a structural core portion and an interior portion, said structural core includes a reinforcing grid structure there throughout, with said reinforcing grid structure being embedded in a moldable material generally within the panel, said reinforcing grid structure extending into and cooperating with separate columns and beams located at the sides of said panels thereby integrating said panels with said columns and beams.
Claim 2
Dependent Claim
94 words
A building wall comprising a plurality of prefabricated interconnected panels where each panel provides infill and substantially contributes to structural stability of the building wall, each prefabricated panel comprising an exterior portion, a structural core portion and an interior portion, said structural core includes a reinforcing grid structure there throughout, with said reinforcing grid structure being embedded in a moldable material generally within the panel, said reinforcing grid structure extending into and cooperating with separate columns and beams located at the sides of said panels thereby integrating said panels with said columns and beams.
Claim 3
Dependent Claim
20 words
A building wall as claimed in claim 1 wherein said moldable material of each panel is a type of cement.
Claim 4
Dependent Claim
19 words

Claim 5
Dependent Claim
18 words
A building wall as claimed in claim 3 wherein each panel includes insulation either side of said core.
Claim 6
Dependent Claim
28 words

Claim 7
Dependent Claim
30 words
A building wall as claimed in claim 5 wherein each panel includes an exterior finish material on one side thereof and an interior finish material on an opposite side thereof.
Claim 8
Dependent Claim
41 words
A building wall as claimed in claim 6 wherein each panel is generally rectangular and has on at least edge portions thereof between said exterior and interior finish materials an elongate cavity which partially accommodate one of said columns or beams.
Claim 9
Dependent Claim
80 words
A building wall comprising a plurality of prefabricated panels connected in an end to end manner, each prefabricated panel comprising an exterior portion, a structural core and an interior portion, each structural core having a reinforcing grid joining and cooperating with vertical and horizontal structural members located between adjacent panels; and wherein said vertical and horizontal structural members are made of a cement type material and said structural reinforcing grids of said panels are partially embedded in said structural members.
Claim 10
Dependent Claim
80 words

Claim 11
Dependent Claim
34 words
A building wall as claimed in claim 8 wherein each panel includes an exterior finish material on one side of said panel and an interior finish material on an opposite side of said panel.
Claim 12
Dependent Claim
33 words
A building wall as claimed in claim 8 wherein each reinforcing grid is embedded in a cement type material within the panel thereby forming a discrete high strength layer of the respective panel.
Claim 13
Dependent Claim
22 words
