Abstract

A connection utilizing a joist hanger to hang a 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 or nails and one or more substantially vertical fire-resistant panels such as drywall.

First claim

We claim:

1. A connection ( 1 ) utilizing a joist hanger ( 2 ) to hang a joist ( 3 ) from a structural support member ( 4 ) in cooperation with a first plurality of fasteners ( 5 ) and one or more vertical drywall panels ( 6 ), the connection ( 1 ) comprising:
a. the one or more drywall panels ( 6 ) providing shielding to the structural support member ( 4 ), each having a front face ( 7 ), a back face ( 8 ) opposite the front face ( 7 ), the panels ( 6 ) being drywall panels such that they have negligible dowel bearing strength compared to the structural support member ( 4 );
b. one or more of the first plurality of fasteners ( 5 ) connecting the joist hanger ( 2 ) to the structural support member ( 4 );
c. the structural support member ( 4 ) having a vertical front face ( 16 ) and the structural support member ( 4 ) having significant dowel bearing strength compared to the one or more drywall panels ( 6 );
d. the joist ( 3 ) supported by the joist hanger ( 2 ), the joist having an end face ( 13 ) spaced away from the vertical front face ( 16 ) of the structural support member ( 4 ); and
e. the joist hanger ( 2 ) supporting the joist ( 3 ), the joist hanger ( 2 ) comprising:
i. one or more back plate members ( 9 ) having one or more back faces ( 10 ) in parallel registration with the front face ( 6 ) of the wood structural support member ( 4 );
ii. a first side member ( 11 ) connected to the one or more back plate members ( 9 ); and
iii. a second side member ( 11 ) connected to the one or more back plate members ( 9 ), the first and second side members ( 11 ) having first and second back edges ( 29 ) with the first and second back edges ( 29 ) having first and second lower portions ( 31 ) and first and second upper portions ( 32 ), the first and second upper portions contacting and registering with the one or more back plate members ( 9 ) with the first and second upper portions ( 32 ) being spaced from each other where the first and second upper portions ( 32 ) contact and register with the one or more back plate members ( 9 );
iv. one or more stand-off members ( 18 ) are connected to the joist hanger ( 2 ) that interface with the end face ( 13 ) of the joist ( 3 ) and space the end face ( 13 ) of the joist away from the vertical front face ( 16 ) of the structural support member ( 4 ); wherein:

f. portions of the one or more panels ( 6 ) are disposed between the end face ( 13 ) of the joist ( 3 ) and the structural support member ( 4 ) and the back face ( 8 ) of one panel ( 6 ) of the one or more panels ( 6 ) interfaces with the front face ( 16 ) of the structural support member ( 4 ).

2. The connection ( 1 ) of claim 1 wherein:
the joist hanger ( 2 ) has a seat member ( 12 ) interconnecting the first and second side members ( 11 ); wherein 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. the joist hanger ( 2 ) has one or more top flanges ( 15 ) connected to the one or more back plate members ( 9 );
b. the structural support member ( 4 ) has a top face ( 17 ); and the one or more top flanges ( 15 ) are fastened to the top face ( 17 ) of the structural support member ( 4 ).

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

5. The connection ( 1 ) of claim 1 wherein:
the first and second side members ( 1 ) have first and second top edges ( 33 ), and side top flanges ( 22 ) are connected to the top edges ( 33 ).

6. The connection ( 1 ) of claim 1 wherein:
the first and second lower portions ( 31 ) being offset from the first and second upper portions ( 32 ), with the upper portions 32 contacting the one or more back plate members ( 9 ), and the lower portions being spaced away from the front face ( 16 ) of the structural support member ( 4 ).

7. The connection ( 1 ) of claim 1 wherein:
the one or more stand-off members ( 18 ) are attached only to the one or more back plate members ( 9 ) and are not connected to the first and second side members ( 11 ).
