Deck framing system
A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.
1. A joist support bracket, comprising:
a first lateral wall;
a second lateral wall disposed opposite the first lateral wall;
a first wing wall extending generally perpendicularly from the first lateral wall;
a second wing wall extending generally perpendicularly from the second lateral wall, the first wing wall and the second wing wall extending away from each other;
a web wall;
a first angled wall disposed between the web wall and the first lateral wall;
a first fold line disposed between the web wall and the first angled wall;
a second fold line disposed between the first angled wall and the first lateral wall;
a second angled wall disposed between the web wall and the second lateral wall;
a third fold line disposed between the web wall and the second angled wall; and
a fourth fold line disposed between the second angled wall and the second lateral wall;
wherein the first lateral wall is biased to form a first non-perpendicular angle between the web wall and the first lateral wall.
2. The joist support bracket of claim 1 wherein the second lateral wall is biased to form a second non-perpendicular angle between the web wall and the second lateral wall.
3. The joist support bracket of claim 2 wherein the first non-perpendicular angle is approximately 95 degrees and the second non-perpendicular angle is approximately 95 degrees.
4. The joist support bracket of claim 1 wherein the first lateral wall, the second lateral wall, the first wing wall, the second wing wall, and the web wall are each portions of a piece of sheet metal.
5. The joist support bracket of claim 4 wherein the piece of sheet metal is galvanized steel.
6. The joist support bracket of claim 5 wherein the piece of sheet metal has a thickness in a range of 0.05-0.10 inches.
7. The joist support bracket of claim 6 wherein the thickness is 0.08 inches.
8. The joist support bracket of claim 1 wherein the first non-perpendicular angle is approximately 95 degrees.
9. The joist support bracket of claim 1 wherein the web wall, the first and second angled walls and the first and second lateral walls define an angled cut-away.
10. A method of forming a joist support bracket, comprising:
providing a piece of sheet metal;
bending the piece of sheet metal to form:
a first lateral wall;
a second lateral wall disposed opposite the first lateral wall;
a first wing wall extending generally perpendicularly and outwardly from the first lateral wall;
a second wing wall extending generally perpendicularly and outwardly from the second lateral wall, the first wing wall and the second wing wall extending away from each other;
a web wall;
a first angled wall disposed between the web wall and the first lateral wall; and
a second angled wall disposed between the web wall and the second lateral wall;
wherein the first lateral wall is biased to form a first non-perpendicular angle between the web wall and the first lateral wall.
11. The method of claim 10 wherein the piece of sheet metal is galvanized steel.
12. The method of claim 11 wherein the piece of sheet metal has a thickness in a range of 0.05-0.10 inches.
13. The method of claim 12 wherein the thickness is 0.08 inches.
14. A joist support bracket, comprising:
a first lateral wall;
a second lateral wall disposed opposite the first lateral wall;
a first wing wall extending generally perpendicularly and outwardly from the first lateral wall;
a second wing wall extending generally perpendicularly and outwardly from the second lateral wall, the first wing wall and the second wing wall extending away from each other; and
a web wall;
wherein the first lateral wall is biased to form a first non-perpendicular angle between the web wall and the first lateral wall and second lateral wall is biased to form a second non-perpendicular angle between the web wall and the second lateral wall;
wherein the first lateral wall, the second lateral wall, the first wing wall, the second wing wall, and the web wall are each portions of a piece of sheet metal.
15. The joist support bracket of claim 14 wherein the piece of sheet metal is a piece of galvanized steel.
16. The joist support bracket of claim 15 wherein the piece of sheet metal has a thickness in a range of 0.05-0.10 inches.

a first lateral wall;
a second lateral wall disposed opposite the first lateral wall;
a first wing wall extending generally perpendicularly from the first lateral wall;
a second wing wall extending generally perpendicularly from the second lateral wall, the first wing wall and the second wing wall extending away from each other;
a web wall;
a first angled wall disposed between the web wall and the first lateral wall; and
a second angled wall disposed between the web wall and the second lateral wall;
wherein the first lateral wall is biased to form a first non-perpendicular angle between the web wall and the first lateral wall; and
wherein the first angled wall is disposed at a 125 degree angle with the web wall and the second angled wall is disposed at a 125 degree angle with the web wall.
