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).
