Spiral staircase plans for wood.

Sep 08,  · The building code requires a minimum of 5 feet, 2 inches because of the tread width minimum of 26 inches. If we add the width of two inch steps, a center column and a handrail, we find that a inch diameter is a minimum for any spiral staircase. I chose a inch diameter to make the stairway easier to walk. These staircases are constructed on a three inch (internal diameter) steel pipe. The treads have a 3 5/8th inch hole in them allowing them to slip fit over the pipe. Between each tread there are short pieces of three and one half inch (internal diameter) pipe which are also slipped over the center pole pipe.

If you have limited space how to change bios settings want to create access to a loft or upper floor, a spiral staircase is an extremely efficient solution. Spiral staircases can be purchased prebuilt and installed in a home, or they can be custom created out from iron or wood. Before you begin installing a spiral staircase, you should first apply for a building permit.

In many cases, if you attempt to purchase a kit without a permit, it will not be shipped to you until you can show a valid building permit. Next you will need to select a set of stairs. You can look at building magazines for ideas and order catalogs from manufacturers or can you find an online source if you want to buy a kit. You can also go to a local wrought-iron artisan to have a custom-designed spiral staircase created specifically for your interior space. Decide where to install the stairs.

Start by cutting a hole in the floor of the second level, or by choosing a spot along the edge of the loft. Do not choose a location that is next to a what organ is located in the lacrimal fossa. Doing so will make the installation difficult.

Set the stairs in place so that they have a headroom of at least 6. Measure the height and diameter of the staircase. Include a clearance of at least 2-inches from the walls and the floor for the handrail. Cut the treads for the staircase all at the same time using a pattern what is a circuit switched network you have made.

The treads should be no wider than 4-inches. You will be gluing the risers together, so vary the wood grain as you glue the pieces together after you have sanded the edges smooth. Mount the center pole to the floor. Make sure that it is level and securely attached to the floor so that it does not move back and forth. Weld the top and bottom steps to the pole.

Install the rest of the steps and attach them to the pole. Purchase a railing that is specifically designed for a spiral staircase. It is extremely difficult to build one unless you have special skills as a carpenter or other artisan experienced.

Install the railing as directed. Spiral staircases offer attractive way to access a tight space. If you have high ceilings, you may even find that a spiral staircase will allow you to build a loft in a room where a full-sized staircase is not possible.

I have built 18 spiral stairways in the last 15 years, all with some wooden components treads and handrails. This article explains how to do so. I recently removed a second-story deck from my house because it was rotting and was in a bad location, in full view of traffic, on a busy street in front of our house.

My wife and I decided that a new steel spiral stairway should take the place of the deck to provide a fire escape and to add a beautiful accent to our home. Above image is courtesy of Salter Spiral Stairs. Planning and Design. Every spiral staircase is built around a center column that rests on a single point at its base See Fig. I dug an inch hole in the ground below the kitchen door 4 feet deep—below the frost line in our Minnesota climate. I filled a cardboard tube with concrete to a height 3 inches above grade and level with the top of the basement block wall.

I used a trowel to smooth and level the concrete. Now we had a good foundation to build on. I needed just one measurement to get started: the total rise. The total height from the concrete foundation to the top of the top step was exactly 9 feet or inches. I recorded that figure and chose to make the stairway turn to the left counterclockwise when walking up. But first I had to consider a few building code requirements in order to lay out the stairway.

The national building code requires that each tread must be at least 26 inches wide. There must be a minimum of 6 feet, 6 inches of headroom at each step.

The handrail must be 34 to 36 inches above each tread nose. The stair railing balusters must not allow a 4-inch ball to pass through. Additionally, the upper platform must extend 7 inches beyond a door that may open out onto it, measured when the door is fully open. The planning and layout for this exterior stairway will apply to any spiral staircase installed anywhere to any height and at any diameter.

Because of the applicable building codes, a stairway that is about 9 feet tall works well when it needs to make approximately one full turn through its vertical travel.

That means that the first step at the bottom is directly below the last step at the top. Someone using the stairway is facing the same direction at the top and at the bottom steps.

This combination of a degree turn over 9 feet of vertical travel also allows the proper headroom required by the building code. To determine the number of steps needed, we divide the inches of vertical height by 7. A 7-inch rise per step is ideal. Since we cannot have an uneven number of steps, we will choose 15 steps.

The top deck will be the 15th step, so we will make 14 steps plus the deck. The depth of each tread the run at the narrow end will be 4 inches to allow it to fit a 4-inch center column with room for welds on the top and sides.

Step run the horizontal depth of each step at the wide outside end can be determined by first choosing the outside diameter of the stairway.

The building code requires a minimum of 5 feet, 2 inches because of the tread width minimum of 26 inches. If we add the width of two inch steps, a center column and a handrail, we find that a inch diameter is a minimum for any spiral staircase.

I chose a inch diameter to make the stairway easier to walk. That made the treads each 32 inches wide instead of the inch minimum. The center column and two treads make a total diameter of 68 inches. The circumference of the stairway is the diameter in inches multiplied by 3. So, 68 inches x 3. The steps need to overlap by one inch to accommodate the newel posts that tie them together and support the handrail and balusters. So we will make the treads inch deep the horizontal measurement, front to back at the outside end.

The newel posts are welded to the heel of one tread and the nose of the tread above it. See Fig. So far we have the following information: The stairway total rise is inches 7. The stairway will turn left on the way up.

The stairway has 15 steps 14 steps plus the top deck. The stairway will make one full degree turn through its travel. The outside diameter is 70 inches, including the newel posts and handrail. The handrail will be 36 inches high. The Top Deck.

The top deck, which, for planning purposes is the 15th step, needs to be at least as wide as the top step, but can be wider. I chose to make mine 42 inches wide to make ample room for the screen door to open easily and for easy access to the first step. The deck must extend 7 inches beyond the screen door when the door is wide open.

My door is 36 inches wide, so I made the top deck 44 inches deep from the house to the outer edge of the deck. I made the guard rails on the upper deck 36 inches high with baluster spacing just under 4 inches. Center Column. I cut it inches long. That allowed inches for 15 steps, 36 inches for the top guard railing, and 2 inches extra for the sake of appearance. In order to make the layout easier, I laid the column horizontally into a simple jig that I made many years ago for just this purpose.

A couple of sawhorses will work just as well. I then laid out soapstone marks for each step approximately 7. As discussed earlier, the top mark is inches from the bottom end of the column and is the attaching point for the top deck.

Tread Construction. I cut the parts with a plasma cutter and took them to a local manufacturer to have them formed. I used the measurements discussed earlier but added 1 inch on the front and back sides to form a stiffening edge that also made the treads look heavier. I tacked the treads onto the center column at my marks, being sure to get them perpendicular to the column in both directions. I was also careful to advance them for the left-hand turn and to overlap them by one in.

After I had a few treads tacked in place I began to attach newel posts at the outside ends of the treads, tying the heel on one tread to the nose of the tread above it at the outside edge of the treads and extending 35 inches above the top tread. The handrail added later made the railing 36 inches high. The newels are 1-inch square tubing cut to 43 inches, with the top ends cut at approximately degrees to approximate the slope of the stairway.

The angle is not critical because the handrail will be welded to the top ends of all the newels. When all the treads and newels were tacked in place I returned to finish all the welding at the center column at each step and around each newel attached to the treads. The most fun part of the whole project was to make the spiral handrail. This process flattened the pipe just slightly and made it fit a hand better. I then tied one end of the pipe to a power pole outside and walked away with the other end, stretching it into a spiral about 9 feet long.

Then, beginning at the middle of the stairway, I tacked the handrail onto the top ends of the newel posts, heating and bending the handrail slightly as needed. When the handrail was in place with no kinks or bulges, I finished the welds and ground them smooth. The deck was by inches with two cross members to help support the load in the center. I notched one corner just slightly to accommodate the center column and welded it in place at the inch mark on the column. Bull-nosed, treated deck boards were added later.

The Finish. With all the welding done and all welds ground and polished, the staircase was ready for a finish. I chose to paint it myself with a good rust-inhibiting primer and an oil-based, flat black paint. It is more durable, but some colors fade and any scratches are not easily repaired.

Remember, your materials list may be different, depending on your stair dimensions and style. If your staircase will be used indoors, you might consider hardwood treads supported by angle-iron frames that are enclosed in carpet.
