a building plan calls for a double 2 by 12 header that is 8’ long
To construct a double 2 by 12 header that is 8' long, you will need two pieces of pressure-treated lumber measuring 2 inches by 12 inches, each 8 feet long.
To build the header:
1. Start by measuring and marking the desired length of 8 feet on both pieces of lumber.
2. Use a circular saw or a miter saw to cut both pieces of lumber to the desired length.
3. Once cut, position the two pieces of lumber side by side, ensuring they are aligned correctly and flush with each other.
4. Apply construction adhesive to the mating surfaces of the lumber to provide additional strength and prevent any movement.
5. To secure the two pieces of lumber together, use 3-inch wood screws or nails through the face of one board into the adjoining board. Space the screws/nails approximately 12 inches apart along the length of the header.
6. Repeat the process for the opposite end of the header, making sure both ends are securely connected.
7. Check the straightness of the header and make any adjustments if necessary.
8. The double 2 by 12 header is now ready to be installed according to the building plan.
It is important to note that building codes and regulations may vary by location, so it is advisable to consult with a local building authority or a licensed professional to ensure compliance with any specific requirements.
To construct a double 2 by 12 header that is 8' long, follow these steps:
Step 1: Gather the materials and tools
- Two pieces of 2 by 12 lumber
- Measuring tape
- Pen or pencil
- Circular saw or handsaw
- Sawhorses or workbench
- Clamps
- Wood glue
- Drill or screwdriver
- 3-inch wood screws or appropriate fasteners
Step 2: Measure and mark the lumber
- Place one of the 2 by 12 pieces on a flat surface such as sawhorses or a workbench.
- Measure and mark the length of 8 feet on one side of the lumber using a measuring tape and pen/pencil.
- Repeat the measurement and marking process on the second piece of the 2 by 12.
Step 3: Cut the lumber
- Using a circular saw or handsaw, carefully cut along the marked lines on both pieces of the 2 by 12 lumber to create two 8-foot-long pieces.
Step 4: Align and secure the lumber
- Place the two cut pieces side by side, lining up the ends and edges.
- Apply wood glue to the mating surfaces of the lumber to enhance the bond.
- Secure the two pieces together by using clamps to hold them in place.
Step 5: Fasten the lumber
- Pre-drill holes along the length of the header to prevent splitting. Use a drill or screwdriver and an appropriate drill bit.
- Insert the 3-inch wood screws or other fasteners through the holes and tighten until the lumber is securely joined.
Step 6: Double-check the measurements and alignment
- Use a measuring tape to confirm that the header is exactly 8 feet in length.
- Check that the edges and ends of the header are flush and level.
Your double 2 by 12 header that is 8' long is now ready to be incorporated into your building plan.
To calculate the dimensions of a double 2 by 12 header for a building plan, you will need to understand the standard sizes and dimensions of lumber.
The term "2 by 12" refers to the nominal dimensions of the lumber, which means it is identified as 2 inches thick and 12 inches wide. However, the actual dimensions of this lumber type are slightly smaller.
The nominal dimensions of 2 by 12 lumber are typically 1.5 inches thick by 11.25 inches wide. Keep in mind that different regions may have slight variations in actual dimensions. Therefore, it's important to verify the actual dimensions of lumber available in your area.
Given that the building plan calls for a double 2 by 12 header that is 8 feet long, you can determine the required amount of lumber and how to assemble it.
1. Calculate the number of pieces required:
Since it is a double header, you'll need two pieces of 2 by 12 lumber.
2. Determine the length:
The header needs to be 8 feet long. However, you need to account for the actual dimensions of the lumber available in your area. As mentioned earlier, the actual dimensions of a 2 by 12 lumber are 1.5 inches thick by 11.25 inches wide.
To convert the length to inches, multiply 8 feet by 12:
8 feet * 12 inches/foot = 96 inches.
3. Assemble the pieces:
To create a double header, you would fasten the two pieces of 2 by 12 lumber side by side, aligning them with their wide faces touching. This will result in an overall width of 22.5 inches (11.25 inches + 11.25 inches) and the same thickness of 1.5 inches.
Therefore, the double 2 by 12 header required for the building plan would be 22.5 inches wide, 1.5 inches thick, and 8 feet (96 inches) long when assembled.
