摘要： Foam wall structures and methods for making them are described. The wall structures include a frame, a sheet metal sheathing overlying a front surface of the frame, a foam panel overlying the sheet metal sheathing, and a foam layer disposed in a cavity defined by the frame and the sheet metal sheathing. Buildings that include such wall structures are also described.

摘要： Foam wall structures and methods for making them are described. The wall structures include a frame, a mesh mechanically fastened to a front surface of the frame, a foam panel at least partially abutting and overlying the mesh, and a foam layer disposed in a cavity defined by the frame, the mesh, and the foam panel. Buildings that include such wall structures are also described.

摘要： Modified and connected foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel attached to the frame, a foam layer disposed in a cavity defined by the frame, and a structural adhesive. The structural adhesive may be disposed in at least one of: (A) an aperture located within the foam layer, and (B) an aperture located between the foam layer and a frame member. In some cases, a cured structural adhesive is located between connecting members of adjacent foam wall structures.

摘要： Methods for manufacturing foam wall structures are described. The methods include placing a wall structure proximate to a robotic arm, orienting an imaging device so that the imaging device on the robotic arm faces a cavity in the wall structure, surveying the cavity using the imaging device, determining a spray foaming pattern to fill the cavity to a selected depth with a foam layer, orienting the spray nozzle so the spray nozzle faces the cavity, and spray-applying the foam-forming composition into the cavity to the selected depth by passing the foam-forming composition through the spray nozzle to form the foam layer. Foam wall structure manufacturing systems that are suitable for carrying out such methods are also described.

摘要： Foam wall structures and methods for making foam wall structures. The wall structures include a frame, a foam panel overlying a front surface of the frame, a first foam layer disposed in a cavity defined by the frame and the foam panel, in which the first foam layer self-adheres to one or more members of the frame, and a second foam layer disposed in the cavity. The second foam layer self-adheres to the first foam layer and has a density that is less than the density of the first foam layer.

摘要： Wall structures and methods of manufacturing wall structures are described. The wall structures include a frame, a foam panel attached to the frame, a brace disposed in a cavity defined by the frame, and a foam layer. The wall structures can impart a high wall racking strength and good thermal performance through the combination of the foam layer, brace, and the foam panels.

摘要： Methods of manufacturing wall structures having high racking strength are described in this specification. The methods include spray applying a foam-forming composition into a cavity of a wall structure, wherein the wall structure is disposed in a climate-controlled spray application station and allowing the foam-forming material to expand within at least a portion of the cavity to form a foam layer deposited in the cavity. In the methods, the foam layer is formed in-situ during the manufacturing method, and the density of the foam layer is selected and the relative humidity and dew point of the air in the climate-controlled spray application station throughout the spray applying is selected so that the wall structure has a racking strength of at least 500 pounds per linear foot.
