Staircase Design and Layout Considerations

Careful planning is crucial for creating a staircase that is safe, functional, and aesthetically pleasing.

Accurately determine the total rise (vertical distance between floors) and divide it by the desired number of steps to calculate the individual rise of each step. Similarly, determine the total run (horizontal distance the staircase will cover) and divide it by the number of steps to calculate the individual run of each step.

Common rise dimensions are between 7 and 8 inches, while common run dimensions are between 10 and 11 inches. The angles of the cuts on the stair stringers will directly influence the final dimensions, so precise marking is crucial for a professional-looking result.

Pay close attention to headroom requirements and ensure that there is adequate clearance above the staircase. Properly account for the thickness of the decking or flooring material when calculating the final rise and run.

With the groundwork laid through careful planning and the acquisition of the right tools and materials, we can now move on to the heart of the project: the installation itself.

Step-by-Step Installation Guide: A Practical Approach

This section provides a detailed, step-by-step guide to installing Simpson Stair Hangers, transforming theoretical knowledge into practical execution.

Preparing the Stair Stringer

The stair stringer is the backbone of your staircase, so meticulous preparation is critical.

Ensuring Proper Cuts and Measurements: Accurate cuts are essential for a safe and aesthetically pleasing staircase. Begin by calculating the total rise (the vertical distance from the lower to upper landing) and the total run (the total horizontal distance the staircase will cover).

Divide the total rise by the desired rise per step (typically between 7 and 7.75 inches) to determine the number of steps needed. This number should be a whole number; if not, adjust the rise slightly until you achieve a whole number result.

Then, divide the total run by the number of steps to determine the run per step (the horizontal depth of each tread).

Use a stair gauge or framing square to mark the rise and run on the stair stringer lumber. Ensure that all cuts are precise and consistent.

A circular saw is ideal for making these cuts, but a handsaw can also be used for greater control, especially when making angled cuts.

Stringer Layout Considerations: Before cutting, consider the placement of the stringers.

Typically, you'll need at least two stringers for a standard staircase, with additional stringers required for wider staircases to provide adequate support.

Ensure that the stringers are spaced evenly apart to distribute the load evenly. Account for the thickness of the treads when marking the cuts.

Pay close attention to the bottom and top of the stringer. The bottom cut typically sits on the ground or a concrete footing, while the top cut attaches to the upper landing.

These cuts need to be precise and level to ensure that the staircase is stable and safe. Remember to account for any landing material thickness.

Attaching the Simpson Stair Hanger to the Supporting Structure

With the stringer prepared, the next step is securely attaching the Simpson Stair Hanger to the supporting structure.

Marking the Location for the Stair Hanger: Precise placement is paramount for a level and structurally sound staircase.

Using your measurements and the stringer layout, determine the exact location for each stair hanger on the supporting structure (typically a ledger board or the house framing).

Use a level to ensure that the hangers are aligned horizontally. Also, use a measuring tape to verify that the hangers are spaced correctly according to the stringer layout.

A speed square can be helpful for marking perpendicular lines to ensure that the hangers are installed straight.

Double-check all measurements before proceeding to the next step.

Using Appropriate Fasteners for Secure Attachment: Once you've marked the locations, it's time to attach the Simpson Stair Hangers to the supporting structure.

Refer to the Simpson Strong-Tie product specifications for the specific stair hanger model you're using.

These specifications will dictate the required type, size, and quantity of fasteners (screws, nails, or bolts) for optimal performance.

Pre-drill pilot holes before driving in the fasteners to prevent the wood from splitting.

Use a drill or impact driver to drive the fasteners securely into the supporting structure. Ensure that the fasteners are flush with the surface of the hanger and that they are not over-tightened, which could damage the hanger or the surrounding wood.

Installing the Stair Stringer into the Simpson Stair Hanger

The final step involves installing the stair stringer into the securely mounted Simpson Stair Hanger.

Ensuring Proper Alignment and Level: Carefully lift the stair stringer into place and align it with the corresponding stair hanger.

Ensure that the stringer sits snugly within the hanger and that it is level. Use a level to verify that the top edge of the stringer is horizontal.

If necessary, make minor adjustments to the stringer or the hanger to achieve perfect alignment.

Securing the Stair Stringer with the Specified Fasteners: Once the stringer is properly aligned and level, secure it to the stair hanger using the fasteners specified by Simpson Strong-Tie.

Again, refer to the product specifications for the correct type, size, and quantity of fasteners. Pre-drilling pilot holes is recommended to prevent the wood from splitting.

Drive the fasteners straight and ensure they are flush with the surface.

Inspect each connection to ensure that it is secure and that there are no gaps or loose fasteners. Repeat this process for each stair stringer, taking care to maintain consistent alignment and spacing throughout the staircase.

With the groundwork laid through careful planning and the acquisition of the right tools and materials, we can now move on to the heart of the project: the installation itself.
