How to Frame a Wall With 135-Degree Corners

Framing walls with 135-degree corners involves creating angled wall studs and cutting mitered joints to ensure a secure and structurally sound framework. Here's a step-by-step guide on how to frame a wall with 135-degree corners:

Tools and Materials Required:

- Circular saw or miter saw

- Measuring tape

- Framing square or bevel gauge

- 2x4 (38mm x 89mm) studs

- 16d nails or 3-inch (76mm) wood screws

- Hammer or nail gun

- Level

Step 1: Measure and Cut Studs

1. Determine the desired height of your wall and cut studs accordingly.

2. Measure and mark a 45-degree angle on one end of each stud using a framing square or bevel gauge.

3. Cut the studs at the 45-degree angle using a circular saw or miter saw.

Step 2: Frame the Corner Studs

1. Place two corner studs perpendicular to each other at the intersection of the walls.

2. Align the angled ends of the studs and secure them together using 16d nails or 3-inch wood screws.

3. Ensure the corner studs are plumb and level.

Step 3: Cut and Install Top Plate

1. Measure the distance between the top of the corner studs, making sure to subtract the width of the bottom plate (usually 2x4 or 38mm x 89mm).

2. Cut the top plate to the measured length and miter the ends at 45 degrees using a circular saw or miter saw.

3. Secure the top plate to the corner studs using 16d nails or 3-inch wood screws.

Step 4: Install Bottom Plate

1. Measure and cut the bottom plate to the same length as the top plate, mitering the ends at 45 degrees.

2. Align and attach the bottom plate to the corner studs using 16d nails or 3-inch wood screws.

Step 5: Install Additional Studs

1. Measure the remaining wall space and cut additional studs to fit between the corner studs.

2. Position and secure the studs to the top and bottom plates using 16d nails or 3-inch wood screws, spacing them 16 inches (406mm) on center.

Step 6: Brace the Corner

1. To add additional strength to the corner, install diagonal braces using 2x4s or other suitable bracing material.

2. Cut the brace at appropriate angles to fit between the studs, typically at a 45-degree angle.

3. Secure the brace to the studs with 16d nails or 3-inch wood screws.

Step 7: Check Level and Plumb

1. Use a level and plumb bob or level app to ensure that the wall studs and plates are level and plumb, respectively.

2. Make adjustments as needed until the studs are perfectly aligned.

By following these steps, you can successfully frame a wall with 135-degree corners, providing a stable and structurally sound framework for your construction project.
