Description
https://www.homebuildingandrepairs.com - Welcome to Part 2 of our series on structurally supporting a stairway! In this video, we explore different design ideas and framing methods to properly support the outside edge of your stair treads.
We’ll look at various custom block designs from simple square blocks to angled and curved cuts and discuss why certain shapes are better at preventing dangerous cantilever cracks. We also cover why upgrading from a 2x12 to a 4x12 might be necessary for a single stringer setup to provide adequate strength. Finally, I’ll show you how to use hardware brackets to connect to the floor framing, and how adding filler boards and 3/4-inch plywood can eliminate weak "hinge points" and prevent the stairs from twisting away from the center.
In this video, you will learn:
How to shape and angle support blocks for the outside of your stairs
Why a 4x12 is a safer bet for single stringer stairways
How to use brackets and hardware to secure the stringer to upper and lower floor framing
Techniques using plywood and filler boards to reinforce the left and right sides of the stairway
Disclaimer: The techniques shown in this video are suggested methods for assembly. Always check with your local building department or a licensed structural engineer to verify that these framing methods are approved for your specific area and project.
