Wheelchair Ramp Design and Construction

A wheelchair ramp is an important tool for helping a loved one live independently in their home. But if not designed correctly, they can be unsafe to use.

ADA regulations require that landings be level at any shift in direction to avoid compound slopes. They must also have an accessible surface for electric wheelchair ramp users.

Design

The ramp's design has to meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can effortlessly navigate the structure. The ramp slope can't exceed a 1:12 ratio, and the landings have to be level in any change of direction or change in the ramp's surface. It must also be constructed using treated lumber that is more durable than lumber that is not treated and can weather precipitation better.

The top and bottom of the ramp need to be free of obstacles such as bushes, trees or other structures that could interfere with the safe passage of the ramp's user. The surface of the ramp must be non-slip and hard. Some municipalities require that the entire ramp be covered with a non-slip surface.

For the frame of the ramp choose treated lumber that is at least 4 inches wide. To make sure the ramp is secure, build posts that are at least 8 feet apart and extend beyond the ground level. The posts must then be connected with the ramp's railings by using spindles. This kind of connection minimizes the possibility of a ramp user falling off the side.

Then, you can build the frame of the ramp using beams that measure 2 by 4 inches in length and joists at least 16 inch long. Make sure that the joists are at a minimum of 18 inches above the ground and that they're secured with joist hangers, which are nails that bind the inside of the joists to prevent them from slipping out of alignment. Attach the ramp decking with a framing nailer.

Add an upper landing to the doorway so that wheelchair occupants can easily manage the doorswing. The landing should be 12 to 24 inches on the handle side of the doors that swing out. The landing for doors that are in-swinging should be 58 x 60 inches to accommodate the threshold of the door and wheelchair van ramps users who need to walk backwards in the doorway.

Install an elevated landing at every alteration in the direction of the ramp to avoid the need for wheelchairs to slam on their brakes as they turn corners. A level landing is easier to move a ramp out of the way if required, so that equipment like lawnmowers can pass beneath it.

Materials

Concrete, wood or aluminium can be used to construct a wheelchair ramp. A professional ramp installer can help you select the most suitable option for your office or home. It is essential to take into consideration your budget and needs when selecting the materials for the ramp. The ramp must also be easy to maintain and safe for use. Some cities require the ramp to be paved with a non-slip surface.

Before you purchase any building materials or begin building, be sure that you have the necessary permits from your local government, and that you comply with all building codes within your area. Incorrect construction materials or techniques can create dangerous conditions for wheelchair users. You can get the most up-to-date information about construction regulations at your local government's building department office library or online.

Wood ramps are often the most affordable of ADA ramp materials, however they require more maintenance than other alternatives. Wood ramps need to be regularly treated with an adhesive to stop decay. Wood splinters can be a problem, and can be especially hazardous for people in wheelchairs. Wood ramps may require additional support to keep the structure standing and steady.

Concrete ramps are extremely durable and last for a long time, but they can be costly. They are also heavy, which requires more labor to install and makes moving the ramp when it's no longer needed difficult. Concrete ramps can withstand the weight of powerful wheelchairs.

Aluminum ramps are lighter and more affordable than steel or concrete. They also have the same durability, strength and resistance to corrosion. They are also cheaper than steel or iron and are an ideal choice for those on a limited budget. Aluminum is environmentally friendly because it is a part of the Earth's crust naturally and is recyclable.

The ramp's upper landing must be at a level level or within 3/8 inches of the threshold of the door, allowing wheelchairs with smaller wheels to move over the ramp without becoming stuck. Ramps that have gaps greater than this won't meet ADA standards. You should also ensure that the ramp moves smoothly between the landing area and the ground surface. The last section of the ramp should have an angled transition to prevent the abrupt stop of wheelchairs as they enter or exit a dwelling.

Installation

A wheelchair ramp is an inclined plane that is erected in addition to or in place of stairs. It lets wheelchair users and those who use strollers or carts to get around areas that would otherwise be difficult to access, such as the front door or a set of sloping steps.

There are many factors to consider when selecting a ramp for wheelchairs such as location, height and cost. A ramp should be placed close to the door as is possible to help prevent unnecessary transportation. It should be placed at a level that the person using it is able to easily navigate. It should also be secured to the ground and clear of obstructions like shrubbery or parked cars.

ADA regulations stipulate that ramps must have handrails either side. These rails should be at least 36 inches apart, and have an edging surface that is smooth or rounded. They should also be connected to the edge of the ramp, and extend 12 inches over it. If a ramp has switchesbacks or an L-shaped layout, handrails must be continuous between the ramp runs.

The length of a ramp depends on the slope, however there are a few common ramps that can be used in all situations. A threshold ramp, for example is a ramp that is flush with the curb's lip or threshold of the doorway. Portable ramps, on the other hand are able to be moved to another location and are available in different sizes. Modular aluminum folding wheelchair ramp ramps can also be built on-site. They are typically used in public or commercial spaces and are usually longer than the threshold and portable ramps.

If you're thinking of an all-weather ramp, be sure you contact your city's building department to see if you need an approval. It is also a good idea to speak with an expert in mobility to determine which kind ramp will be the most suitable for your needs and the space you have. In certain situations, installing permanent ramps can increase 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 frequently. You'll need to conduct regular inspections and repair any structural issues as they occur. This will ensure that the ramp meets all ADA requirements, and is safe for the users.

Regularly cleaning wooden ramps is required to get rid of dirt and other debris that may block access. Keeping the ramp clean will also prevent moisture from accumulating under the surface and causing the onset of rot. Preservatives and stains for wood only work only if the ramp is clean before application.

Wheelchair ramps can be more challenging to maintain than other types of ramps because they are more susceptible to wear and tear. The most important thing to do is ensure you have the appropriate tools for the job. To ensure that all fixings are secure and secure you'll need an excellent set of screwdrivers and gauge spanners. It is also important to regularly check the handrails to ensure they are in a good condition and are free of corrosion or damage. It's possible that, over time, and with repeated use, some of the bolts and fittings that hold the handrails on may come loose and cause an extremely dangerous risk for those using the ramp.

It is also essential to ensure that the surface the ramp is grippy enough particularly in winter, when the conditions are difficult. You'll need to clean away any dirt, leaves or other debris that might block and cause slippage. You'll also need to apply an ice melt that's non-corrosive on the fold ramp for wheelchair surface to avoid injuries and slipping.

Think about buying "snow tires" or traction wheels for your wheelchair if you intend to use it during the winter. These wheels are made to track better on snowy surfaces and uneven surfaces. They will help you stay on your ramp longer than regular wheelchair tires. You can also make use of heating pads or heating tape to melt the ice and snow on the ramp prior to it accumulates.
