Abstract

A wallboard structure is disclosed having a metal sheet attached by means of an adhesive to a wallboard panel, such as a gypsum panel. The wallboard structure is attached to the framing studs of a building with the metal sheet adjacent the studs. The metal sheet resists in-plane or shear loads imposed of the framing structure of the building due to exterior environmental conditions, and thereby helps keep the wallboard panel from cracking.

Claims

1. A building shear wall structure for accommodating in-plane or shear loads imposed on the wall structure comprising:

a plurality of framing studs forming a part of the building;

a plurality of composite wallboard panels, each composite panel comprising only one wall board panel and one thin sheet of high strength material attached to and covering one entire side of the wallboard panel, the panel and attached thin sheet of high strength material forming together the entire composite wallboard panel; and

securing means for attaching the wallboard panels to the framing studs such that the thin sheet of high strength material sits directly against the framing studs with the securing means penetrating the composite panel underlying the sheet of high strength material and the studs, the thin sheet of high strength material having a strength at least as great as a steel sheet having a thickness within the range of 0.015 to 0.060 inches, the sheet of high strength material being capable of resisting anticipated in-plane or shear loads imposed on the shear wall structure due to environmental conditions such as wind and earthquakes.

2. The composite wallboard panel of claim 1 wherein the thin sheet of high strength material is metal.

3. The composite wallboard panel of claim 2 wherein the metal is steel.

4. The composite wallboard panel of claim 3 wherein the steel sheet has a thickness within the range of 0.015 to 0.06 inches.

5. The composite wallboard panel of claim 2 wherein the wallboard panel is a sheet of gypsum.

6. The composite wallboard panel of claim 1 wherein the thin sheet of high strength material is plastic.

7. The shear wall structure of claim 1 wherein the attaching means comprises screws.

8. The shear wall structure of claim 7 wherein the attaching means comprises nails.

9. A building shear wall structure for accommodating in-plane or shear loads imposed on the wall structure comprising:

a plurality of framing studs forming a part of the building;

a plurality of composite wallboard panels, each composite panel comprising a single gypsum type wallboard panel and one thin steel sheet having a thickness within the range of 0.015 to 0.060 inches, attached to and covering one entire side of the wallboard panel, the panel and attached steel sheet forming the entire composite and wallboard panel; and

a plurality of fasteners extending through the composite wallboard panels and into the framing studs so that the steel sheets sit flush against the framing studs, each steel sheet having a strength capable of resisting in-plane or shear loads anticipated to be imposed on the shear wall due to wind and earthquakes.

10. The shear wall structure of claim 9 wherein the fasteners are screws.

11. The shear wall structure of claim 9 wherein the fasteners are nails.
