Wheelchair Ramp Design and Construction

A wheelchair ramp can be an effective tool to help a loved one live more independently at home. But if not designed correctly they could be unsafe to use.

ADA regulations require landings to must be level with any change in direction, to avoid compound slopes. They must also have a surface that is gripping for wheelchair users.

Design

The ramp's design should be in line with the Americans with Disabilities Act standards to allow wheelchairs to move around the structure easily. For instance, the ramp's slope cannot exceed the ratio 1:12 and must have level landings at any angle or change in the ramp's surface. It must also be constructed using treated lumber that is more durable than untreated lumber and is able to withstand rain better.

The sides and top of the ramp should be clear of obstacles like bushes, trees or other structures that could hinder the safe passage of the ramp's user. In addition the surface of the ramp must be hard and non-slip. Some municipalities require an anti-slip running surface along the ramp's entire length.

Make use of treated lumber that is at minimum four inches wide for the frame of the ramp. Create posts to anchor the ramp, making sure they are at minimum eight feet apart and that they extend below the ground level. The posts should be connected with the ramp's railings by using spindles. This type of connection decreases the risk of a ramp user falling off the side.

Next, build the ramp's frame using joists that are at least 16 inches long and beams of 2 by 4 inches. The joists should be at least 18 inches above the ground and secured by hangings for joists which are nails that grip inside the joists to prevent them from sliding. Attach the ramp decking with a framing nailer.

Add an upper landing near the doorway to enable wheelchair users to control the doorswing easily. The landing should be wide enough to allow at least 12-24 inches of "elbow space" on the handle side for out-swing doors. The landing for doors that are in-swinging should be 58 x 60 inches to accommodate the threshold of the door as well as a wheelchair user who needs to walk backwards in the doorway.

Install a level landing whenever you alteration in the direction of the ramp to avoid the requirement for wheelchairs to step on their brakes while turning corners. A level landing allows you to move the ramp away from the way if necessary to allow lawnmowers or other equipment can slide under it.

Materials

The materials used to construct ramps for wheelchairs could be wood, concrete or aluminum. A professional ramp installer can help you choose the best option for your home or office. It is important to consider your specific needs and budget when choosing the materials for the ramp. The ramp should also be easy to maintain and safe to use. Some cities require that the ramp be laid with a non-slip surface.

Before you purchase any material or begin construction, make sure you have the appropriate permits from your local authority and ensure that you adhere to all building codes within your area. Incorrect construction materials or methods can result in dangerous conditions for folding wheelchair ramp-users. You can find up-to-date construction regulations in your local building department of the government, library or on the internet.

Wood ramps are typically the most affordable of ADA ramp materials, however they require more care than other alternatives. The surface of wood ramps should be treated regularly with a sealer in order to stop rot and warping. Wood can split and be dangerous for people who use wheelchairs. Wood ramps can also need additional support to maintain the structure.

Concrete ramps are extremely durable and long-lasting, but they can be costly. They are heavy, which means more labor is required to install them, and they can make it difficult to move the ramp after it is no longer needed. Concrete ramps are strong enough to withstand the weight of power wheelchairs.

Aluminum ramps are lighter and more affordable than concrete or steel. They also have the same durability, strength, and resistance to corrosion. They are also cheaper than steel and iron which makes them a great option for people on a tight budget. Aluminum is also environmentally friendly, since it is naturally present in the Earth's crust and can be recycled.

The ramp's upper landing must be in a level area, or within 3/8 inches of the threshold of the door to allow wheelchairs with smaller wheels to go over the ramp without getting stuck. Ramps with a gap that is larger than this will not comply with ADA standards. It is also important to make sure that the ramp transitions smoothly between the upper landing and the ground surface. The ramp's last section should be curved to stop wheelchairs from abruptly stopping when entering or leaving a home.

Installation

A wheelchair ramp is a sloped plane ramp that can be erected as an alternative to or in the place of steps. It lets handicap wheelchair ramp users and those who use strollers or carts to navigate areas that are otherwise difficult to access, such as an entranceway or a set of steep steps.

There are a variety of factors to consider when choosing a ramp for a Wheelchair ramp for Car boot, including location, height and cost. The ramp should be placed closest to the door to avoid unnecessary journeys. It should also be placed at a level that is easy to use by the person using it. It should be securely fixed to the floor and clear of any obstructions such as shrubbery, parked cars or other obstacles.

ADA regulations require that ramps should have handrails on either side. The rails must be at minimum 36" apart and have a smooth or rounded gripping surface. In addition, they must be connected to the ramp and extend at least 12 inches beyond the edge of the ramp. Handrails must be continuous when a ramp is designed with switchbacks, or in an L-shaped layout.

The length of the ramp is determined by the incline. However there are standard ramp types which are suitable for all situations. A threshold ramp, for example is placed flush against the lip of the curb or threshold of the doorway. Portable ramps are, on the other hand, can be moved to a new place and come in a variety of sizes. Modular aluminum ramps can also be constructed on-site. These ramps are commonly employed in public or commercial areas, and tend to be longer.

Consult with your city's building department to determine the need for a permit for a permanent ramp. It is also advisable to speak with an expert in mobility about the kind of ramp for wheelchair that is best for your needs and the space. In some cases, installing permanent ramps can improve the value of your house.

Maintenance

It is important to keep your ramp for wheelchairs in good condition, especially if it will be used frequently. You'll need to perform regular inspections and repair any structural problems as they arise. This will help ensure that the ramp is compliant with all ADA requirements and is safe for all users.

Wooden ramps require regular maintenance to remove debris and dirt that could block access. Keep the ramp clean to avoid moisture from accumulating under the surface. This can lead to the onset of rot. Wood preservatives and stains only work properly only if the ramp is clean before application.

Wheelchair ramps are more difficult to maintain than other ramps as they are more susceptible to wear and tear. It is essential to have the right tools. A good set of gauge spanners as well as screwdrivers is vital to ensure that all fixings are tight and secure. You should also regularly inspect the handrails for signs of damage or corrosion. Over time, and with repeated usage, it's possible for some of the bolts or fittings the handrails to become loose. This can pose an issue for anyone using the ramp.

It is also essential to make sure that the surface of the ramp is sufficiently grippy particularly in winter, when the conditions can be difficult. You'll need to clean off any leaves, dirt or other debris that could obstruct and cause slippage. You'll also want to apply an ice melt that's non-corrosive to the ramp's surface to avoid injuries and slipping.

You should consider purchasing "snow tires" or traction wheels for your wheelchair if plan to use it throughout the winter. These wheels are designed to be more efficient on snowy and uneven surfaces. They can help you stay on your ramp more effectively than standard wheelchair tires. You can also use heating tape or pads to melt the snow and ice on the ramp before it accumulates.
