Wheelchair Ramp Design and Construction
A ramp for wheelchairs is a crucial tool in helping a loved one to live at home independently. But if not designed correctly, they can be dangerous to use.
ADA regulations require that landings be level at every change in direction, to avoid compound slopes. They also need to provide a gripping surface 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 navigate the structure easily. The ramp's slope shouldn't exceed a 1:12 ratio, and the landings must be level at any change in direction or shift on the ramp surface. It also must be constructed out of treated lumber which is more durable and can withstand precipitation much better than untreated lumber.
The sides and top of the ramp must be clear of obstacles such as trees, bushes or other structures that can hinder the safe movement of the ramp's user. 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 of at least four inches in width for the frame of the ramp. Build posts to secure the ramp, ensuring they are at minimum eight feet apart and that they extend below ground level. Spindles should be used to join the posts with the ramp's railings. This type of connection is recommended because it decreases the chance of a ramp operator falling off the side of the ramp.
Then, you can build the frame of the ramp using beams 2 by 4 inches in size, and joists at least 16 inch long. The joists should be at minimum 18 inches above the ground and secured by Joist hangings, which are nails that fit within the joists to stop them from sliding. Attach the ramp decking with a framing nailer.
Add an upper landing to the doorway so that the wheelchair-bound occupants are able to easily maneuver the doorswing. This landing should be large enough to give at least 12-24 inches of "elbow space" on the handle side of out-swing doors. For doors with in-swing the landing should be at least 58 inches by 60 inches to accommodate the door's threshold and a person in wheelchair who must walk backwards through the doorway.
Install a level landing when you change the direction of the ramp to prevent wheelchairs from having to hit their brakes at corners. A level landing also makes it easier to move the ramp out of the way, if needed, so that lawnmowers or other equipment can go under it.
Materials
aluminium wheelchair ramps (
Imoodle.Win), wood, or concrete can be used to construct ramps for wheelchairs. A professional ramp installer will assist you in choosing the right option for your home or
wheelchair ramp minivan office. It is important to consider your individual needs and budget when selecting the materials for the ramp. The ramp should be easy to maintain, and it should be safe to use. Certain cities require that the ramp be laid with a non-slip surface.
Before you purchase any building materials or begin building, be sure that you have the appropriate permits from your local government, and ensure that you adhere to all building codes within your area. The wrong materials or construction techniques can create dangerous conditions for wheelchair users. You can find the most current construction regulations in your local government building department library, or on the internet.
Wood ramps are the most affordable alternative for ADA ramp materials. However, they require more maintenance. Wood ramps need to be regularly treated with an adhesive to prevent decay. Wood can splinter and can be hazardous for those using wheelchairs. Wood ramps can require additional support to ensure the structure remains upright and stable.
Concrete ramps can be costly however they are durable and long-lasting. They are also heavy, which means more work to construct and can make moving the ramp once it's no longer required difficult. Concrete ramps are sturdy enough to support the weight of power wheelchairs.
Aluminum ramps weigh less than concrete or steel however they possess the same strength and corrosion resistance. They are also more affordable than steel and iron, making them an excellent option for people on budgets. Aluminum is a green choice because it is a part of the earth's crust naturally and can be recycled.
The ramp's upper landing must be level or within 3/8 inches of the threshold of the door to allow wheelchairs
wheel chair carrier with ramp smaller wheels to pass across the ramp without getting stuck. Ramps with gaps that is larger than this will not comply with ADA standards. You should also make sure that the ramp transitions smoothly between the landing area and the ground surface. The last section of the ramp should have an angled transition to prevent an abrupt stop for wheelchairs when they enter or leave an apartment.
Installation
A wheelchair ramp is a sloped plane ramp that can be erected as an alternative to or in addition to steps. It allows wheelchair users and people who use strollers or carts to access areas that would otherwise be difficult to reach like a front door or a set up of steep steps.
There are several considerations when choosing a wheelchair ramp that should be considered, including the height, location and cost. The ramp should be placed as close as possible to the door in order to avoid unnecessary journeys. It should be located at a height that the person using it is able to easily walk on it. It should be securely anchored to the floor and free of any obstructions such as shrubbery, parked cars or other obstacles.
ADA regulations require that ramps must have handrails on either side. The rails must be at least 36" apart and have a smooth or rounded gripping surface. They should also be connected to the edge of the ramp, and extend 12 inches beyond it. If a ramp is equipped with switchbacks or an L-shaped layout handrails should be a continuous length between the ramp's runs.
The length of the ramp is determined by the slope. However there are a few common ramp types that can be used in all situations. A threshold ramp, for example is placed flush against the curb's lip or the threshold of the doorway. Portable ramps are, on the other hand are able to be moved to a different location and come in a variety of sizes. There are also modular aluminum ramps that can be assembled on site. These ramps are typically used in commercial or public areas and are usually longer.
If you're considering a permanent ramp, be sure you contact your city's building department to determine if you require permits. It's recommended to consult with an expert in mobility to find
fold out wheelchair ramp what type of ramp is best suited to your needs and the space you have. In some cases, installing permanent ramps can boost the value of your house.
Maintenance
It's crucial to ensure your wheelchair ramp is well maintained, especially if are going to use it often. It is essential to conduct regular inspections and address any structural issues as they arise. This will help ensure the ramp complies with all ADA requirements and is safe for all users.
Wooden ramps require frequent cleaning to remove dirt and debris that can obstruct access. Cleaning the ramp regularly will also prevent moisture from accumulating under the surface and causing rot. Stains and wood preservatives only work properly only if the ramp is cleaned prior to applying.
Wheelchair ramps are more difficult to maintain than other ramps due to the fact that they are more likely wear and tear. It is essential to have the right tools. To make sure that all fixings are secure and tight you'll require an appropriate set of screwdrivers as well as gauge spanners. 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 some of the fittings and bolts which hold the handrails in place could loosen and cause a major safety concern for those who use the ramp.
Another crucial aspect is to ensure that the surface of the ramp has sufficient grip, particularly in winter, when conditions can be difficult. You'll need to remove any leaves, dirt and other debris that could block the surface and cause slippage. You'll also need to apply an ice melt that's non-corrosive to the ramp surface to avoid slips and injuries.
Consider purchasing "snow tires" or traction wheels for your wheelchair if plan to use it throughout the winter. These wheels are designed to track better on snowy surfaces and uneven surfaces. They will allow you to stay on your ramp for longer than normal wheelchair tires. You can also use heating tape or pads to melt snow and ice on the ramp before it builds up.
