Wheelchair Ramp Design and Construction

A wheelchair ramp can be an effective tool to assist a loved one live more independently at home. If they are not designed properly they could be unsafe to use.

ADA regulations require landings to be level at every change in direction, to avoid compound slopes. They also must provide a gripping surface for vehicle wheelchair ramps users.

Design

The ramp's design must be in line with the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs effortlessly navigate the structure. The ramp's slope shouldn't exceed a ratio of 1:12, and the landings have to be level at any change in direction or change in the ramp surface. The ramp must also be constructed out of treated lumber that is more robust and can withstand precipitation much better than untreated lumber.

The ramp's top and bottom must be free of any obstacles, such as trees or bushes, or any other structures which could interfere with the safety of the user. In addition the surface of the ramp must be smooth and non-slip. Some municipalities require that the entire ramp be covered with a non-slip surface.

Use treated lumber at minimum 4 inches in width for the ramp frame. To make sure the ramp is secure, build posts that are at least 8 feet apart and extend below the ground level. The posts should then connect to the ramp's railings using spindles. This kind of connection minimizes the chance of a ramp operator slipping off the ramp.

Then, construct the ramp's frame using joists that are at least 16 inches long and 2 by 4 inch beams. Make sure that the joists are at a minimum of 18 inches above the ground and that they are secured with joist hangers, which are nails that bind the inside of the joists to prevent them from sliding off the ground. Attach the ramp decking using a framing nailer.

Create an upper landing in the doorway, allowing wheelchair users to control the doorswing without difficulty. The landing should be 12 to 24 inches on the handle side of the doors that swing out. For doors that swing in the landing should be at minimum 58 by 60 inches to allow for the threshold of the door and a person in a wheelchair who needs to roll backward through the doorway.

Install a level landing when you change the direction of the ramp, to avoid wheelchairs from having to slam their brakes into corners. A level landing also makes it easier to move the ramp out of the way if necessary, so that lawnmowers or other equipment can pass underneath it.

Materials

The material used to construct a wheelchair ramp can be wood, concrete or aluminum. A professional ramp installer will assist you in choosing the right option for your home or office. When choosing the material for the ramp, it's crucial to consider your budget and the specific requirements. The ramp should be simple to maintain and safe for use. Certain cities require the ramp to be covered with a non-slip surface.

Be sure to check with your local government for permits prior to building or buying any materials. Also, be certain to follow the local building codes. Utilizing the incorrect materials or methods of construction could result in hazardous conditions for wheelchair users. You can find current construction requirements in your local building department library, or on the internet.

Wood ramps are often the cheapest option for ADA wheel chair ramp design materials. However they require more care. The surface of wood ramps need to be regularly treated with a sealer to prevent warping and rot. Wood splinters can be a problem, and is particularly hazardous for those who are in wheelchairs. Wood ramps also require additional support to maintain the structure.

Concrete ramps can be costly however they are durable and long lasting. They are also heavy, which demands more labor to install and makes moving the ramp after it's no longer required difficult. Concrete ramps are strong enough to withstand the light weight wheelchair ramps (see here now) of power wheelchairs.

Aluminum ramps are less heavy and more affordable than steel or concrete. They also have the same durability, strength and resistance to corrosion. They are also more affordable than steel and iron, making them an excellent option for those with a tight budget. Aluminum is also green, since it is found naturally in the Earth's crust and can be recycled.

The upper ramp's landing needs to be at a level, or within 3/8 inch of the door threshold ramp for wheelchair in order to allow the front wheels of smaller wheelchairs to move over it without getting stuck. Ramps that have gaps greater than this will not meet ADA standards. It is also important to ensure that the ramp is smooth transitioning from the upper landing to the ground. The last section of the ramp must have a an angled transition to prevent the abrupt stop of wheelchairs as they enter or exit the dwelling.

Installation

A wheelchair ramp is an inclined plane that is erected on top of or in lieu of stairs. It allows wheelchair users and those who use carts or strollers to access areas that would otherwise be difficult to access.

When choosing a wheelchair access ramp, there are a variety of factors to consider, such as the location, height and cost. A ramp should be situated near the door as it is possible to avoid unnecessary journeys. It should also be placed at an elevation that is easy to use by the person using it. It should be securely fixed to the floor and clear of obstructions, such as car parks, shrubs or other obstacles.

ADA regulations require that ramps are equipped with handrails either side. These rails should be at 36 inches apart and have an edging surface that is rounded or smooth. Additionally, they should be connected to the ramp and extend at least 12 inches beyond the ramp edge. Handrails should be continuous if a ramp is designed with switchbacks or in an L-shaped layout.

The length of the ramp is determined by the slope. However there are standard ramp types which are suitable for all situations. For instance the threshold ramp is placed flush along the lip of a curb, or the threshold of a doorway, while portable aluminum ramps for wheelchairs ramps can be moved from one spot to another and come in a variety of sizes. There are also aluminum ramps that are modular that can be assembled on site. These ramps are commonly used in public or commercial areas and are typically longer.

Contact your city's construction department to determine the need for a permit for an ongoing ramp. It is also a good idea to consult with a mobility expert to determine which kind ramp will be the most suitable for your needs and the space you have. In some cases, installing an all-weather ramp can boost the value of your home.

Maintenance

It is essential to keep your ramp for wheelchairs in good condition especially if it will be used frequently. You'll have to conduct regular inspections, and fix any structural problems as they occur. This will ensure that the ramp complies with all ADA requirements and is safe for all users.

Regular cleaning of wooden ramps is essential to remove dirt and debris that can block access. Keeping the ramp clean will also stop moisture from accumulating under the surface and causing the onset of rot. Stains and wood preservatives only work when the ramp is clean before application.

Wheelchair ramps are more challenging to maintain than other types of ramps because they are more susceptible to wear and tear. It is crucial to have the right tools. A good set of gauge spanners as well as screwdrivers will be crucial to ensure that all fixings are secure and secure. You should also regularly inspect the handrails to see if there are signs of damage or corrosion. It's possible that over time, as they are used repeatedly and use, the bolts and fittings that secure the handrails could loosen, which can be 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 challenging. You'll need to sweep away any dirt, leaves and other debris that could obstruct the surface 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 prevent slips and causing injury.

You should consider buying "snow tires" or traction wheels for your wheelchair if you are planning to use it for the duration of the winter. These wheels are designed to be more efficient on snowy and uneven surfaces. They will allow you to remain on your ramp more effectively than regular wheelchair tires. Alternately, you can put heating pads or tape along the ramp's surface to help melt ice and snow before it accumulates.
