Abstract
Abstract A prefabricated building wall is particularly suited for residences. The wall has a metal outer frame, and inner frames of metal may be located therein for doors and windows. Non-metallic stiffening members are interconnected within the outer frame in a diagonal grid. Hardenable plastic foam is injected into the frame to serve as insulation and support. The stiffening members are I-beams with apertures along their webs to allow them to be interlaced.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
A method of forming a building wall, comprising: providing an outer frame that is located in a plane for defining the perimeter of the wall; providing a plurality of stiffening members, each stiffening member having slot means for interconnecting with other stiffening members; interconnecting the stiffening members within the frame in an X-shaped diagonal pattern with the stiffening members located in the plane of and extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame to provide reinforcement; then filling the frame with a hardenable plastic foam.
Claim 2
Independent Claim
99 words
A method of forming a building wall, comprising: providing an outer frame that is located in a plane for defining the perimeter of the wall; providing a plurality of stiffening members, each stiffening member having slot means for interconnecting with other stiffening members; interconnecting the stiffening members within the frame in an X-shaped diagonal pattern with the stiffening members located in the plane of and extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame to provide reinforcement; then filling the frame with a hardenable plastic foam.
Claim 3
Dependent Claim
49 words
The method according to claim 1 further comprising the steps of: placing within the outer frame at least one inner frame located in the plane of the outer frame and defining a portal, and interconnecting the stiffening members between the inner and outer frames prior to filling with foam.
Claim 4
Dependent Claim
88 words
The method according to claim 1 further comprising the steps of: placing within the outer frame at least one inner frame located in the plane of the outer frame, and defining a portal; placing a horizontal beam across the frame at the top of the portal; interconnecting a plurality of metal truss members in a triangular pattern between the horizontal beam and the frame above the portal; and interconnecting the stiffening members between the inner and outer frame and through the truss members prior to filling with foam.
Claim 5
Independent Claim
99 words
A method of forming a building wall, comprising: providing a rectangular outer frame defining the perimeter of the wall; providing a plurality of nonmetallic, resilient stiffening members, each stiffening member having a plurality of apertures along its length for interlacing with others of the stiffening members; interlacing the stiffening members through the apertures within each other in diagonal pattern extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame to define a grid within the outer frame; and filling the outer frame with a hardenable plastic foam.
Claim 6
Independent Claim
99 words
A method of forming a building wall, comprising: providing a rectangular outer frame defining the perimeter of the wall; providing a plurality of nonmetallic, resilient stiffening members, each stiffening member having a plurality of apertures along its length for interlacing with others of the stiffening members; interlacing the stiffening members through the apertures within each other in diagonal pattern extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame to define a grid within the outer frame; and filling the outer frame with a hardenable plastic foam.
Claim 7
Independent Claim
132 words
A method of forming a building wall, comprising: providing an outer frame that is located in a plane defining the perimeter of the wall; providing a plurality of non-metallic, resilient stiffening members of identical cross-sectional dimension, each stiffening member having an I-beam configuration with a pair of parallel flanges separated by a web, the web having a plurality of apertures spaced along the length of the stiffening member for interlacing with other stiffening members; interlacing the stiffening members by pushing them through the apertures within one another to define a grid with a diagonal pattern located in the plane of and extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame; then filling the frame with a hardenable plastic foam.
Claim 8
Independent Claim
132 words
A method of forming a building wall, comprising: providing an outer frame that is located in a plane defining the perimeter of the wall; providing a plurality of non-metallic, resilient stiffening members of identical cross-sectional dimension, each stiffening member having an I-beam configuration with a pair of parallel flanges separated by a web, the web having a plurality of apertures spaced along the length of the stiffening member for interlacing with other stiffening members; interlacing the stiffening members by pushing them through the apertures within one another to define a grid with a diagonal pattern located in the plane of and extending to the outer frame; connecting to the outer frame the ends of the stiffening members which extend to the outer frame; then filling the frame with a hardenable plastic foam.
Claim 9
Dependent Claim
35 words
The method according to claim 5 further comprising deflecting each stiffening member in a cross-sectional plane perpendicular to the length of the stiffening member while pushing the stiffening members through the apertures within one another.
