Wheelchair Ramp Design and Construction
A ramp for wheelchairs can be an effective tool to help a loved one live more independently at home. If they are not designed properly they could be dangerous to use.
ADA regulations require landings to must be level with any change in direction, to avoid compound slopes. They also require an area that is grippy for wheelchair users.
Design
The ramp's design should be in line with the Americans with Disabilities Act standards so that wheelchairs are able to maneuver the structure with ease. The ramp slope can't exceed a 1:12 ratio and the landings have to be level at any change in direction or shift in the ramp's surface. It also must be constructed out of treated lumber, which is more durable and withstands rain better than untreated lumber.
The ramp's top and bottom should be free of obstacles like trees or bushes, or any other structures which could hinder the user's safe passage. In addition, the ramp's surface must be non-slip and hard. Some municipalities require that the entire ramp be covered with an anti-slip surface.
Use treated lumber at least four inches in width for the frame of the ramp. Build posts to secure the ramp, ensuring that they are at least eight feet apart and that they extend above the level of the ground. Spindles are the best way to join the posts with the railings of the ramp. This kind of connection is preferred because it reduces the risk of an operator of the ramp falling off the side of the ramp.
Then, you can build the frame of the ramp van with wheelchair ramp beams of 2 by 4 inches in size and Joists that are at least 16 inches long. Make sure that the joists stand a minimum of 18 inches above ground level and that they're secured with hangers for joists, which are nails that grip the inside of the joists to prevent them from sliding out of alignment. Attach the ramp decking with a framing nailer.
Install an upper landing on the doorway to ensure the wheelchair-bound occupants are able to easily maneuver the doorswing. The landing should be enough to allow at least 12-24 inches of "elbow room" on the handle side for out-swing doors. 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 a wheelchair who needs to walk backwards through the doorway.
Install a level landing whenever you change in ramp direction to prevent the necessity for wheelchairs to hit on their brakes while turning corners. A level landing makes it simpler to remove a ramp of the path if needed, so that lawnmowers and other equipment can move under it.
Materials
The materials used to construct ramps for wheelchairs could be made of wood, concrete or aluminum. A professional ramp installation company can help you decide the best option for your home or business. It is essential to take into consideration your specific needs and budget when choosing the materials for the ramp. The ramp should be simple to maintain and safe for use. Some cities require that the ramp be laid with a non-slip surface.
Before you purchase any building materials or begin construction, make sure you have the appropriate permits from your local authority and that you comply with all building codes in your area. Making use of the wrong materials or construction methods could result in hazardous conditions for wheelchair users. You can get the most up-to-date information about construction regulations at the building department of your local government office or library, or on the internet.
Wood ramps are typically the most affordable of ADA ramp materials, however they require more maintenance than other alternatives. The surface of wood ramps should be treated regularly with a sealer to avoid rot and warping. Wood can split and be dangerous for people using wheelchairs. Wood ramps may also require additional support to ensure the structure is maintained.
Concrete ramps are extremely durable and last for a long time however they can be expensive. They are also heavy, which requires more work to construct and can make moving the ramp when it's no longer required difficult. Concrete ramps can withstand the weight of powerful wheelchairs.
Aluminum ramps are lighter and more affordable than concrete or steel. They also have the same strength, durability and corrosion resistance. They are also cheaper than iron or steel which makes them a great option for those on a limited budget. Aluminum is also green, since it is naturally found in the Earth's crust and can be recycled.
The ramp's upper landing should be in a level area, or within 3/8 inches of the threshold of the door, allowing wheelchairs with smaller wheels to go across the ramp without getting stuck. Ramps with gaps higher than this meet ADA standards. It is also important to ensure that the ramp is smooth transitioning from the upper landing to the ground. The ramp's final section should be curved to ensure that wheelchairs don't stop abruptly at the point of leaving or entering the home.
Installation
A ramp for wheelchairs is an inclined plane that is used in addition to or instead of stairs. It allows wheelchair users as well as those who use strollers or carts to access areas that would otherwise be difficult to easy access wheelchair ramps.
There are a variety of factors to consider when choosing a ramp for a wheelchair such as height, location and cost. A ramp should be located close to the door as is possible to help prevent unnecessary journeys. It should be located at a level that the person using it is able to easily walk on it. It should also be anchored to the ground and free of obstructions, like trees or parked cars.
ADA regulations state that ramps should have handrails on either side. The rails should be at least 36" apart and have smooth or rounded gripping surface. They must also be anchored to the edge of the ramp and extend 12 inches beyond it. Handrails must be continuous when a ramp is designed with switchbacks or in an L-shaped layout.
The length of a ramp varies on the incline, but there are several common ramp types that can be used in most situations. For example, a threshold ramp sits flush along the lip of a curb or the threshold of a doorway while portable wheelchair ramp ramps can be moved from one spot to another and are available in a variety of sizes. Modular aluminum ramps can be assembled on-site. These are usually used for public or commercial areas and are typically longer than the threshold and portable ramps.
Contact your city's construction department to determine the need for a permit for an enduring ramp. You should also speak to an expert in mobility about the type of ramp that is best for your needs and the space. In certain cases installing an ongoing ramp could boost the value of your home.
Maintenance
It's important to make sure your ramp for wheelchairs is maintained, particularly if you will be using it often. You'll need to conduct regular inspections and repair any structural issues that arise. This will help ensure that the ramp complies with all ADA requirements and is safe for all users.
Regular cleaning of wooden ramps is necessary to remove dirt and debris that could block access. Keep the ramp spotless to stop moisture from accumulating under the surface. This can cause the onset of rot. The wood preservatives or stains will only work if the ramp has been thoroughly cleaned before application.
Wheelchair ramps are more challenging to maintain than other types of ramps, since they are more prone to wear and wear and tear. The most important thing is to ensure you have the appropriate tools for the job. A set of gauge spanners as well as screwdrivers are vital to ensure that all fixings are secure and secure. It's also important to check regularly the handrails to ensure they are in a good condition and do not show signs of corrosion or damage. It's possible that over time, and with repeated use and use, the fittings and bolts that hold the handrails on may loosen and pose an extremely dangerous risk for people who use the ramp.
Another crucial aspect is to ensure that the ramp's surface has enough grip, especially during winter when conditions may be difficult. You'll need to sweep up any dirt, leaves or other debris that might block and cause slippage. Additionally, you'll need to apply a non-corrosive ice melt to the ramp's surface before winter arrives to avoid slips and causing injury.
If you're planning to use your ramp during winter months, you should consider purchasing wheels for traction or "snow tires" for your wheelchair. These wheels are designed to better track on snowy surfaces and uneven surfaces. They can help you remain on your ramp more effectively than normal wheelchair tires. You can also utilize heating pads or tape to melt snow and ice on the ramp prior to it builds up.
