Abstract

A connection utilizing a joist hanger to hang a generally horizontal joist or beam from a wood structural support member such as a top plate or header in cooperation with a first plurality of fasteners such as screws and one or more generally vertical drywall panels.

First claim

We claim:

b. the first plurality of fasteners ( 5 ), each of the first plurality of fasteners ( 5 ) having a shank ( 13 );
c. the wood structural support member ( 4 ) having a generally vertical front face ( 16 ) and the wood structural support member ( 4 ) having significant dowel bearing strength compared to the drywall panels ( 6 ), the wood structural support member ( 4 ) supporting the shanks ( 13 ) of the first plurality of fasteners ( 5 );
d. the joist ( 3 ); and
e the joist hanger ( 2 ) supporting the joist ( 3 ), the joist hanger ( 2 ) comprising:
i. a first back plate member ( 9 ) with a first back face ( 10 ) in parallel registration with the front face ( 7 ) of a first panel ( 6 ) of the one or more drywall panels ( 6 );
ii. a second back plate member ( 9 ) with a second back face ( 10 ) in parallel registration with the front face ( 7 ) of the first panel ( 6 ) of the one or more drywall panels ( 6 );
iii. a first side member ( 11 ) connected to the first back plate member ( 9 ); and
iv. a second side member ( 11 ) connected to the second back plate member ( 9 ), wherein:
(a) at least one of the first plurality of fasteners ( 5 ) passes through the first back plate member ( 9 ) and the one or more panels ( 6 ) and into the wood structural support member ( 4 );
(b) at least one of the first plurality of fasteners ( 5 ) passes through the second back plate member ( 9 ) and the one or more drywall panels ( 6 ) and into the wood structural support member ( 4 );
(c) the joist ( 3 ) is supported by the joist hanger ( 2 ); and
(d) the one or more drywall panels ( 6 ) are between the joist hanger ( 2 ) and the wood structural support member ( 4 ) and the back face ( 8 ) of one panel ( 6 ) of the one or more drywall panels ( 6 ) interfaces with the front face ( 16 ) of the wood structural support member ( 4 ).

2. The connection ( 1 ) of claim 1 wherein:
a. the joist hanger has a seat member ( 12 ) interconnecting the first and second side members ( 11 ); wherein:
i. the joist ( 3 ) rests on the seat member ( 12 ) between the first and second side members ( 11 ).

3. The connection ( 1 ) of claim 1 wherein:
a. no part of the joist hanger ( 2 ) contacts the front face ( 16 ) of the wood structural support member ( 4 ).

4. The connection ( 1 ) of claim 3 wherein:
a. each of the one or more drywall panels ( 6 ) has a top edge face ( 14 );
b. the joist hanger ( 2 ) has a first top flange ( 15 ) connected to the first back plate member ( 9 ) and a second top flange ( 15 ) connected to the second back plate member ( 9 ); wherein:
i. the first and second top flanges ( 15 ) extend over the top edge faces ( 14 ) of the one or more drywall panels ( 6 ) and are the only parts of the joist hanger that contact the wood structural support member ( 4 ).

5. The connection ( 1 ) of claim 4 wherein:
a. the first and second top flanges ( 15 ) are fastened to the wood structural support member ( 4 ).

6. The connection ( 1 ) of claim 5 wherein:
a. the wood structural support member ( 4 ) has a top face ( 17 ); and
b. the first and second top flanges ( 15 ) are fastened to the top face ( 17 ) of the wood structural support member ( 4 ).

7. The connection ( 1 ) of claim 6 wherein:
a. the first and second top flanges ( 15 ) are fastened to the wood structural support member ( 4 ) with a second plurality of fasteners ( 5 ).

8. The connection ( 1 ) of claim 1 wherein:
a. the first plurality of fasteners ( 5 ) that attach the joist hanger ( 2 ) to the wood structural support member ( 4 ) are all within the upper one-third of the first and second back plate members ( 9 ).

9. The connection ( 1 ) of claim 8 wherein:
a. the wood structural support member ( 4 ) is a top plate ( 4 ) having one or more parts ( 50 ), and the top plate has a height less than one-third the height of the joist hanger ( 2 ).

10. The connection ( 1 ) of claim 9 wherein:
a. the parts ( 50 ) of the top plate ( 4 ) are two pieces of 2×4 dimensional lumber ( 50 ).

11. The connection ( 1 ) of claim 1 wherein:
a. each of the one or more drywall panels ( 6 ) has a top edge face ( 14 );
b. the wood structural support member ( 4 ) has a top face ( 17 ); and
c. the top edge face ( 14 ) of each of the one or more drywall panels ( 6 ) is located at the level of the top face ( 17 ) of the wood structural support member ( 4 ) or above the top face ( 17 ) of the wood structural support member ( 4 ).

12. The connection ( 1 ) of claim 1 wherein:
a. the first and second back plate members ( 9 ) have first and second top edges ( 24 ), respectively; and
b. the first and second back faces ( 10 ) of the first and second back plate members ( 9 ) interface with the front face ( 7 ) of the first panel ( 6 ) of the one or more drywall panels ( 6 ) below the first plurality of fasteners ( 5 ) that pass through the first and second back faces ( 10 ) and the one or more drywall panels ( 6 ) and into the wood structural support member ( 4 ), wherein:
i. the interface between first and second back faces ( 10 ) of the first and second back plate members ( 9 ) and the front face ( 7 ) of the first panel ( 6 ) of the one or more drywall panels ( 6 ) extends at least three times as far from the first and second top edges ( 24 ) of the first and second back plates ( 24 ) as the location of any of the first plurality of fasteners ( 5 ) in the first and second back plate members ( 9 ).
