Wheelchair Ramp Design and Construction
A ramp for wheelchairs is an effective device to aid a loved one live more independently at home. If not designed correctly they can be unsafe to use.
ADA regulations require level landings on any changes in direction, to avoid compound slopes. They must also provide a grippy surface for wheelchair users.
Design
The ramp's design has to meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can comfortably navigate the structure. The ramp's slope shouldn't exceed a 1:12 ratio and the landings must be level at any change of direction or change in the ramp surface. It should also be constructed from treated lumber that is more durable than untreated and can weather precipitation better.
The sides and top of the ramp should be free of obstructions such as trees, bushes or other structures that could interfere with the safe passage of the ramp's user. Additionally, the surface of the ramp must be hard and non-slip. Some municipalities require that the entire ramp be coated with an anti-slip surface.
Make use of treated lumber that is at minimum four inches wide for the frame of the ramp. Create posts to anchor the ramp, ensuring they are at least eight feet apart and that they extend above the ground level. The posts should then connect to the ramp's railings using spindles. This type of connection is preferred because it reduces the risk of the ramp operator falling off the side of the ramp.
Then, build the ramp's frame with beams of 2 by 4 inches in length and Joists that are at least 16 inches long. The joists should be placed at minimum 18 inches above the ground and secured by joist hangings which are nails that sit inside the joists to prevent them from sliding. Attach the ramp decking with a framing nailer.
Add an upper landing near the doorway to allow wheelchair occupants to manage the doorswing with ease. This landing should have 12 to 24 inches on the handle side of the doors that swing out. For in-swing doors, the landing must be at least 58 by 60 inches to allow for the threshold of the door and the person in wheelchair who has to walk backwards through the doorway.
Install a level landing when you change the direction of the ramp to stop wheelchairs from having their brakes at corners. A level landing is easier to remove a ramp of the way if required, so that equipment like lawnmowers can pass beneath it.
Materials
The material used to construct the ramp for wheelchairs can be made of wood, concrete or aluminum. A professional ramp installation company can help you decide the best option for your business or home. It is crucial to think about your specific needs and budget when selecting the materials for the ramp. The ramp should be simple to maintain and safe to use. Certain cities require the ramp to be covered with a non-slip surface.
Make sure to inquire with your local government for permits prior to building or purchasing materials. Also, be certain to follow the local building codes. Making metal ramps for wheelchair of the incorrect materials or methods of construction can lead to dangerous conditions for wheelchair users. You can find the most up-to-date information on construction requirements at the building department of your local government office or library, or on the internet.
Wood ramps are often the cheapest alternative for ADA ramp materials. However they need more maintenance. The wood ramp's surface need to be regularly treated with a sealer to avoid rot and warping. Wood can splinter, which can be especially hazardous for people in wheelchairs. Wood ramps may also require additional support to ensure the structure remains standing and steady.
Concrete ramps can be costly but they are also durable and long-lasting. They are heavy, which means more work is required to construct them, and they can make it difficult to move the ramp once they are no longer needed. Concrete ramps are able to withstand the weight of large power wheelchairs.
Aluminum ramps weigh less than concrete or steel however they possess the same strength and corrosion resistance. They are also less expensive than steel or iron and are an excellent choice for those with a tight budget. Aluminum is environmentally friendly since it is found in the earth's crust naturally and is able to be recycled.
The upper landing of the ramp should be level or within 3/8 inch of the door threshold to allow for the smaller front wheels of wheelchairs to pass over it without getting stuck. Ramps with a gap larger than this won't meet ADA standards. You should also make sure that the ramp transitions smoothly between the landing area and the ground. The final section of the ramp should be curved to ensure that wheelchairs don't stop abruptly at the point of leaving or entering a home.
Installation
A ramp for wheelchairs is a ramp that has a plane ramp that can be erected as an alternative or in the place of steps. It lets wheelchair users and those who use strollers or carts to access areas that are otherwise difficult to access like a front door or a set of steep steps.
When choosing a wheelchair accessible ramp, there are numerous factors to consider, such as the location, height, and cost. A ramp should be located as close to the door as possible to help prevent unnecessary travel. It should also be placed at an elevation that is easy to use by the person who is using it. It should also be secured to the ground and free of obstructions like trees or parked cars.
ADA regulations stipulate that ramps must have handrails on either side. The rails must be at least 36 inches apart, and have a gripping surface that is rounded or smooth. In addition, they must be affixed to the ramp and extend at least 12 inches over the edge of the ramp. Handrails should be continuous if the ramp is designed with switchbacks or an L-shaped layout.
The length of a ramp is contingent on the incline, however there are several standard ramps that can be used in most situations. A threshold ramp, for instance is placed flush against the lip of the curb or threshold of the doorway. Portable ramps are, however are able to be moved to a new location and are available in various sizes. There are also modular aluminum ramps that can be constructed on site. They are typically used for public or commercial spaces and are usually longer than the threshold and ramps that are portable.
If you're considering a permanent ramp, be sure you check with the building department of your city to determine if you require an approval. Also, you should consult a mobility specialist about the type of ramp that is best for your needs and space. In some instances, installing an all-weather ramp can increase the resale value of your home.
Maintenance
It is crucial to maintain your wheelchair ramp, especially if it will be used frequently. You'll have to conduct regular inspections, and fix any structural problems as they arise. This will ensure that the ramp is in compliance with all ADA requirements and is safe for all users.
Regular cleaning of wooden ramps is required to get rid of dirt and other debris that could block access. Keep the ramp spotless to stop moisture from accumulating beneath the surface. This can cause rot. Preservatives and stains for wood only work only if the ramp is cleaned prior to applying.
Wheelchair ramps can be more challenging to maintain than other kinds of ramps because they are more prone to wear and wear and tear. It is crucial to have the proper tools. To make sure that all fixings are secure and tight, you will need an excellent set of screwdrivers as well as gauge spanners. You should also regularly inspect the handrails for signs of corrosion or damage. It's possible that over time, and with repeated use and use, the fittings and bolts that secure the handrails may come loose and pose an extremely dangerous risk for those who use the ramp.
Another crucial aspect is to ensure that the surface of the ramp has enough grip, especially in winter when conditions can be challenging. You will need to sweep away any dirt, leaves or other debris that could block the ramp and cause slippage. In addition, you'll want to apply an ice melt that is not corrosive to the ramp surface before winter arrives to avoid slips and causing injury.
Consider purchasing "snow tires" or traction wheels for your wheelchair if intend to use it during the winter. These are specifically designed to aid in tracking on uneven and snowy surfaces, so they'll be more efficient than standard wheelchair tires at aiding you to stay on the ramp. Alternately, you can put heating pads or tape along the ramp surface to help melt snow and ice before it accumulates.
