Abstract

A concealed connection mechanism for connecting a pair of stair stringers to the front face of a rim joist.

Claims (24)

1 . A stair hanger for connecting a stair stringer to a rim joist, the hanger comprising:

a base including two end sections, the end sections being connectable to the stringer or the rim joist, said base having first and second ends, a free side edge and a flange connection side edge opposite to the free side edge;

a pair of flanges connectable to the stair stringer, each flange of the pair of flanges connected to one of the end sections of the base along the flange connection side edge;

wherein

the two end sections of the base are separated by a bend line extending transversely to a longitudinal axis of the base and the stair hanger is symmetrical about the bend line.

2 . The hanger of claim 1 , wherein the pair of flanges are perpendicular to the base.

3 . The hanger of claim 1 , wherein the base and the pair of flanges each includes at least one connecting member receiving opening.

4 . The hanger of claim 1 , said hanger being reversible.

5 . A hanger set for connecting first and second stair stringers to a rim joist, said hanger set comprising:

first and second reversible hangers each connectable to the rim joist, said first hanger connectable to the first stair stringer and said second hanger connectable to the second stair stringer, each of first and second hangers being substantially identical and including:

a base including two end sections, the end sections being connectable to one of the first or second stair stringers or the rim joist, the base having first and second ends, a free side edge and a flange connection side edge opposite to the free side edge;

a pair of flanges connectable to the stair stringer, each flange of the pair of flanges connected to one of the end sections of the base along the flange connection side edge; wherein

the two end sections of the base are separated by a bend line extending perpendicular to a longitudinal axis of the base and each of the stair hangers are symmetrical about the bend line.

6 . The hanger set of claim 5 , wherein each of the pair of flanges of each of the first and second hangers are perpendicular to each of the bases.

7 . The hanger set of claim 5 , wherein the base and the pair of base flanges of each of the first and second hangers includes at least one connecting member receiving opening.

8 . A stair and hanger structure comprising:

a structural member having a substantially vertical front face;

first and second laterally spaced stair stringers, each of the stair stringers including an end adjacent to the front face, a bottom edge and an inner side face, the inner side faces of said first and second stringers facing one another;

a first and second hanger each having;

a base including two end sections connectable to one of the first or second stair stringers or the front face, the base having first and second ends, a free side edge and a flange connection side edge opposite to the free side edge;

a pair of flanges each connected to the inner side face of the first or the second stair stringer, each flange of the pair of flanges connected to one of the end sections of the base along the flange connection side edge.

9 . The structure of claim 8 , wherein the base and the pair of flanges of each of said first and second hangers includes at least one connecting member receiving opening.

10 . The structure of claim 8 , wherein each of end sections of the base are connected to each other for limited bending movement along a fold line separating the end sections.

11 . The structure of claim 8 , wherein said structural member is a rim joist.
