Abstract

A reinforced stud-framed wall, including a bottom plate; first and second vertical studs; a member supported on the bottom plate, the member having a compression strength greater than a compression strength of the bottom plate; the first vertical stud having a bottom end supported on the member with a first contact area, whereby a load on the first contact area is spread over a first area on the bottom plate larger than the first contact area; and the second vertical stud having a bottom end supported on the member with a second contact area, whereby a load on the second contact area is spread over a second area on the bottom plate larger than the second contact area.

First claim

I claim:

1. A reinforced stud-framed wall, comprising:
a) a tie rod anchored to a foundation;
b) a bottom plate disposed directly on a subfloor;
c) the bottom plate has a compression strength greater than a compression strength of the subfloor; and
d) a plurality of vertical studs supported on the bottom plate;
e) the tie rod extending through the bottom plate; and
f) the bottom plate is operably attached to the subfloor.

2. The reinforced stud-framed wall as in claim 1 , and further comprising:
a) a bearing plate disposed on the bottom plate and a fastener on the bearing plate, the bearing plate having a contact area on the bottom plate; and
b) the bearing plate transferring a load onto the subfloor over an area larger than the contact area.

3. The reinforced stud-framed wall as in claim 2 , wherein the fastener includes an axially expandable fastener.

4. The reinforced stud-framed wall as in claim 2 , wherein:
a) the bottom plate includes an engineered lumber; and
b) the fastener includes an axially expandable fastener.

5. The reinforced stud-framed wall as in claim 2 , wherein the fastener includes a nut.

6. The reinforced stud-framed wall as in claim 1 , wherein the bottom plate includes hollow metal.

7. The reinforced stud-framed wall as in claim 1 , wherein the bottom plate includes solid metal.

8. The reinforced stud-framed wall as in claim 1 , wherein the bottom plate includes an engineered lumber.

9. A reinforced stud-framed wall, comprising:
a) a bottom plate having a compression strength;
b) a solid non-metallic member supported on the bottom plate over a first contact area;
c) the member having a compression strength greater than the compression strength of the bottom plate;
d) a bearing plate disposed on top of the member, the bearing plate having a second contact area on the member;
e) a tie rod extending through the member and the bearing plate;
f) a fastener for securing the bearing plate on the member and the tie rod; and
g) the bearing plate transferring a load onto the bottom plate through the member over a projected area on the first contact area that is larger than the second contact area.

10. The reinforced stud-framed wall as in claim 9 , wherein the fastener includes a nut.

11. The reinforced stud-framed wall as in claim 9 , wherein the fastener includes an expandable fastener.

12. The reinforced stud-framed wall as in claim 9 , wherein the member has sufficient thickness such that the second contact area encompasses the first contact area.

13. The reinforced stud-framed wall as in claim 9 , wherein the compression strength of the member is lower than the compression strength of the bearing plate and higher than the compression strength of the bottom plate.

14. A method for transferring a load onto a wood part of a stud-framed wall, comprising:
a) interposing a solid non-metallic member between the load and the wood part, the member making a contact area on the wood part; and
b) providing the member with a compression strength greater than a compression strength of the wood part such that the load is transferred onto the wood part over a projected area on the contact area that is larger than an area of application of the load on the member.

15. The method as in claim 14 , and further comprising the step of providing wood, engineered lumber, or plastic for the member.

16. The method as in claim 14 , wherein the load is applied through a bearing plate disposed on the member.

17. The method as in claim 14 , wherein the load is applied through a bottom end or a top end of a stud.

18. A reinforced stud-framed wall, comprising:
a) horizontal wood part having a first compression strength;
b) a solid non-metallic member bearing onto the horizontal wood part from a load applied on a first area on the member, the member having a contact area on the wood part, the member having a second compression strength greater than the first compression strength; and
c) the member transferring the load to the wood part over a projected area on the contact area that is larger than the first area.

19. The reinforced stud-framed wall as in claim 18 , wherein the member includes wood or engineered lumber.

20. The reinforced stud-framed wall as in claim 18 , wherein the horizontal wood part includes a bottom plate of the wall, or a subfloor.

21. The reinforced stud-framed wall as in claim 18 , wherein:
a) the horizontal wood part includes a top plate of the wall; and
b) the member bears onto an underside of the top plate.

22. The reinforced stud-framed wall as in claim 18 , wherein:
a) a bottom end of a vertical stud bears on the member; and
b) the first area comprises an area of the bottom end.

23. The reinforced stud-framed wall as in claim 18 , wherein:
a) a bearing plate bears on the member; and
b) the first area comprises an area of the bearing plate in contact with the member.

24. The reinforced stud-framed wall as in claim 18 , wherein:
a) the horizontal wood part includes a top plate of the wall;
b) the member bears onto an underside of the top plate;
c) a top end of a vertical stud bears on an underside of the member; and
d) the first area comprises an area of the top end.

25. The reinforced stud-framed wall as in claim 18 , wherein:
a) the horizontal wood part includes a bridge member;
b) the member bears onto an underside of the bridge member;
c) a top end of a vertical stud bears on the member underneath; and
d) the first area comprises an area of the top end.

26. The reinforced stud-framed wall as in claim 18 , wherein the horizontal wood part includes a cross-laminated timber panel.

27. A reinforced stud-framed wall, comprising:
a) a bottom plate disposed on a wood part, the bottom plate being made of sheet metal having U-shaped cross-section with a bottom wall and sidewalls;
b) a member supported on the bottom wall over a first contact area;
c) a bearing plate disposed on top of the member, the bearing plate having a second contact area on the member;
d) a tie rod extending through the member and the bearing plate;
e) a fastener for securing the bearing plate on the member and the tie rod; and
f) the bearing plate transferring a load onto the bottom wall through the member over a projected area on the first contact area that is larger than the second contact area.

28. The reinforced stud-framed wall as in claim 27 , wherein the member has a compression strength greater than the compression strength of the wood part.

29. A reinforced stud-framed wall, comprising:
a) a bottom plate having a compression strength;
b) a stud bay in an end portion of the stud-framed wall, the stud bay including an outer stud and an inner stud spaced apart from the outer stud, the outer stud and the inner stud being supported on the bottom plate;
c) a member supported on the bottom plate over a first contact area within the stud bay, the member having a compression strength greater than the compression strength of the bottom plate; and
d) a first stud adjacent to the outer stud, the first stud including a first bottom end supported on the member over a second contact area, the first stud transferring a first load onto the bottom plate through the member over a projected area on the first contact area that is larger than the second contact area.
