Abstract

A wall connection system is disclosed, which includes a horizontal building frame component with a first vertical face that has a first slot. The system further includes a prefabricated wall structure with a plurality of parallel studs and an elongate member connect to each stud. The elongate member has a second vertical face with a second slot and is parallel to the first vertical face. The long axis of the first slot is perpendicular to the long axis of the second slot. A fastener assembly connects the horizontal building frame component to the wall structure, through the slots.

Claims (36)

1. A wall connection system, comprising:

a horizontal building frame component having a first vertical face, the first vertical face having a first slot,

a modular wall panel assembly including:

a plurality of at least three parallel studs defining a primary wall plane, and

a strongback structure including an angle iron connected orthogonally to each of the plurality of studs, the angle iron including an expanse oriented parallel to the wall plane, the expanse having a second slot that is parallel the primary wall plane, and

a fastener assembly connecting the horizontal building frame component to the wall panel assembly through the first slot and the second slot, without directly connecting the studs to the building frame component,

wherein the expanse is parallel to the first vertical face, and a long axis of the first slot is orthogonal to a long axis of the second slot.

2. The wall connection system of claim 1 , wherein the horizontal building frame component is an I-beam.

3. The wall connection system of claim 1 , wherein the fastener assembly includes a threaded rod, a first nut threadedly engaging a first end of the rod and a second nut threadedly engaging a second end of the rod.

4. The wall connection system of claim 3 , wherein the rod is configured to flex under seismic loads.

5. The wall connection system of claim 1 , wherein the fastener assembly includes a threaded rod, a first pair of nuts engaging a first end portion of the rod on opposite sides of the first vertical face, and a second pair of nuts engaging a second end portion of the rod on opposite sides of the expanse.

6. The wall connection system of claim 1 , wherein the wall panel assembly is spaced at least 2 inches from the horizontal building frame component.

7. The wall connection system of claim 1 , wherein the fastener assembly is configured to accommodate both push and pull forces.

8. The wall connection system of claim 1 , wherein the wall connection system includes fewer fastener assemblies than the number of studs of the plurality of parallel studs.

9. The wall connection system of claim 1 , wherein the expanse of the angle iron has multiple slots, each configured to receive the fastener assembly for fastening the wall panel assembly to a building structure without directly connecting the studs to the building structure.

10. The wall connection system of claim 1 , wherein the number of second slots in the strongback structure is at least two less than the number of the plurality of parallel studs.

11. The wall connection system of claim 1 , wherein the angle iron is fixed in contact with each of the plurality of parallel studs.

12. A wall connection system, comprising:

a horizontal building frame component having a vertical face, the vertical face having a slot,

a modular wall panel assembly including:

a plurality of at least three parallel studs defining a primary wall plane, and

a strongback structure including an aperture and connected orthogonally to each of the plurality of studs, and

a fastener assembly connecting the horizontal building frame component to the wall panel assembly through the slot and the aperture, without directly connecting the studs to the building frame component,

wherein the primary wall plane is parallel to the vertical face.

13. The wall connections system of claim 12 , wherein the strongback structure includes a rectangular tube.

14. The wall connection system of claim 13 , wherein the plurality of studs are metal, and the tube is welded to each of the studs.

15. The wall connection system of claim 12 , wherein the slot of the horizontal building frame component has a horizontal long axis.

16. The wall connection system of claim 15 , wherein the aperture of the strongback structure is a slot.

17. The wall connection system of claim 12 , wherein the strongback structure is connected to each of the plurality of studs at a position spaced from a top end and a bottom end of the stud.

18. The wall connection system of claim 12 , wherein the fastener assembly includes a threaded rod and at least one pair of nuts engaging the rod.

19. A wall connection system, comprising:

a horizontal building frame component having a vertical face, the vertical face having a horizontal slot,

a modular wall panel assembly including:

a plurality of at least three parallel studs defining a primary wall plane, and

a strongback structure including a rectangular tube parallel to the primary wall plane and orthogonal to the studs, the rectangular tube being directly connected to each of the studs and having an aperture, and

a fastener assembly connecting the horizontal building frame component to the wall panel assembly through the slot and the aperture, without directly connecting the studs to the building frame component.
