How to Build a Wheelchair Ramp
Step 1: Select a Location. Step 2: Determine the Length of Your Ramp. Step 3: Determine the Shape of Your Ramp. Step 4: Measure and Lay Out the Landing. Step 5: Adjust the Batter Boards. Step 6: Mark the Ground. Step 7: Install the Footings. Step 8: Pour the Concrete.

How long should a ramp be for 3 steps?

Here are some factors that should be considered: Stairs typically run about 7.5 inches high each so for three stairs a standard rise or height would be about 22 inches. The ADA [Americans with Disabilities Act] recommends 1 foot for ramp for every one inch of rise.

What is the proper angle for a handicap ramp?

Maximum slope for hand-propelled wheelchair ramps should be 1″ of rise to every 12″ of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5″ rise to 12″ length (7.1 degree angle; 12.5% grade). Minimum width should be 36″ (inside rails) – (48″ is ideal).

Can I use plywood for a wheelchair ramp?

Can I use plywood for a wheelchair ramp? For an indoor ramp, plywood might work, but when building a wheelchair ramp outdoors, use pressure-treated lumber.

How do you cut a stringer for a ramp?

Use a circular saw to cut triangular stringers based on your rise and slope measurements. The nominal size of the boards you select depends on the ramp rise. For example, 2- x 6-inch lumber could be used as stringers if the rise is less than 5 1/2-inches; a rise greater than that would require a 2- x 8-inch board.

How do you calculate a ramp?

How do you calculate the slope of a ramp?
slope[ratio] = rise : run.slope[angle] = arctan(rise/run)slope[%] = 100% * rise/run = 100% * tan(angle)

How do you determine ramp length?

Determining Ramp Length:

Measure total rise (how many inches from lower level to upper level) and divide by the slope.

How far can a ramp go before a landing?

How far can a ramp go without a landing? A ramp with a slope between 1:12 and 1:16 can have a maximum horizontal length of 30′ | 9.14 m without a landing. A ramp with a slope between 1:16 and 1:20 can have a horizontal run up to 40′ | 12.19 m before requiring a landing.

What plywood should I use for a ramp?

The quality of wood dictates how strong and durable the plywood is. For instance, birch has phenomenal surface hardness, therefore birch plywood is one of the best. And a great choice as the riding surface for many indoor ramps.
