Wheelchair Ramp Design and Construction
A ramp for wheelchairs can be an important tool to assist the person you love independently at home. If not designed correctly they can be unsafe to use.
ADA regulations require level landings at any changes in direction, to avoid compound slopes. They also must provide a gripping surface for wheelchair users.
Design
The ramp design must meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs are able to comfortably navigate the structure. For instance, the ramp's slope cannot exceed the ratio 1:12 and must have landings that are level upon any direction change or shift in the ramp's surface. It must also be constructed out of treated lumber which is more durable and withstands rain better than untreated lumber.
The sides and top of the ramp must be clear of obstacles such as bushes, trees or other structures that could hinder the safe movement of the ramp's user. In addition, the ramp's surface must be hard and non-slip. Some municipalities require the use of an anti-slip running surface on the ramp's entire length.
Make use of treated lumber that is at minimum four inches wide for the frame of the ramp. To ensure the ramp is secured, construct posts that are at least 8 feet apart and extend beyond the level of the ground. Spindles should be used to join the posts with the railings of the ramp. This kind of connection is recommended because it decreases the chance of an operator of the ramp falling off the side of the ramp.
Then, construct the ramp's frame using Joists that are at minimum 16 inches long and beams that measure 2 by 4 inches. The joists should be at least 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 using a framing nailer.
Add an upper landing to the doorway to ensure the wheelchair-bound occupants are able to easily maneuver the doorswing. This landing should be large enough to provide at least 12-24 inches of "elbow space" on the handle side for out-swing doors. For doors with in-swing the landing should be at minimum 58 by 60 inches to allow for the threshold of the door and a person in wheelchair folding ramp who must walk backwards through the doorway.
Install an elevated landing at every alteration in the direction of the ramp to avoid the requirement for wheelchairs to step on their brakes when turning corners. A level landing also makes it easier to move the ramp away from the way, if needed, so that lawnmowers or other equipment can pass underneath it.
Materials
Concrete, wood or aluminium can be used to build ramps for wheelchairs. A professional ramp installation service will help you choose which is best for your home or business. When choosing the material for the ramp, it's crucial to consider your budget and requirements. The ramp should be simple to maintain and should be safe for use. Certain cities require that the ramp be laid with an anti-slip surface.
Be sure to check with your local government for permits prior to building or purchasing materials. Also, be certain to follow the local building codes. Incorrect construction materials or techniques could create hazardous conditions for wheelchair users. You can find up-to-date construction regulations in your local building department library, or on the internet.
Wood garden ramps for wheelchair users are usually the least expensive choice of ADA ramp materials, however they require more care than other alternatives. Wood ramps need to be treated regularly with sealers to prevent rot. Wood can splinter and be dangerous for people who use wheelchairs. Wood ramps also require extra support to keep the structure in place.
Concrete ramps are extremely durable and last for a long time however they can be expensive. They are heavy, which means that more labor is required to put in them and can make it difficult to move the ramp after it is it is no longer required. Concrete rubber ramps for wheelchairs are strong enough to withstand the light weight wheelchair ramps of power wheelchairs.
Aluminum ramps are lighter than steel or concrete however they offer the same strength and corrosion resistance. They are also cheaper than iron or steel and are an excellent choice for those on a tight budget. Aluminum is environmentally friendly because it is a part of the earth's crust naturally, and is recyclable.
The ramp's upper landing needs to be at a level level, or within 3/8 inches of the threshold of the door to allow wheelchairs with smaller wheels to pass over the ramp without becoming 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 final section of the ramp should have a beveled transition to avoid the abrupt stop of wheelchairs when they exit or enter an apartment.
Installation
A wheelchair ramp is a sloped plane that can be installed as an alternative to or in the place of steps. It allows wheelchair users and those who use carts or strollers to access areas that are otherwise difficult to access.
When choosing a wheelchair accessible ramp, there are numerous factors to consider, such as the location, height and price. Ideally, a ramp should be located close to the door as is possible to prevent unnecessary journeys. It should be set at a height that the person using it is able to be able to easily access it. It should also be fixed to the ground and clear of obstructions, like trees or parked cars.
ADA regulations stipulate that ramps must have handrails either side. The rails should 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 the ramp. If a ramp has switchesbacks or an L-shaped layout, handrails should be a continuous length 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 most situations. For example, a threshold ramp sits right on the edge of a curb or at the threshold of a doorway, while portable ramps can be moved from one location to another and are available in a variety of sizes. There are also modular aluminum ramps that can be built on site. They are typically used for commercial or public spaces, and are typically larger than the threshold and ramps that are portable.
Contact your city's construction department to determine the need for a permit for an enduring ramp. It is also a good idea to consult with a mobility specialist to find out what type of ramp is best suited to your requirements and the space that you have. In some instances the installation of a permanent ramp can even increase the value of your home.
Maintenance
It's important to make sure your lightweight wheelchair ramps for vans ramp is well maintained, especially if are going to use it frequently. You'll need to conduct regular inspections, and fix any structural problems as they occur. This will help ensure the ramp is in compliance 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 clean to avoid moisture from building up under the surface. This can cause decay. The wood preservatives or stains only work when the ramp has been thoroughly cleaned prior to application.
Wheelchair ramps are more challenging to maintain than other kinds of ramps because they are more prone to wear and tear. It is important to have the proper tools. To make sure that all fixings are secure and tight you'll need an appropriate set of screwdrivers as well as gauge spanners. Also, you should regularly check the handrails for signs of damage or corrosion. With time and repeated use, it's possible that some fittings or bolts that hold on the handrails to come loose. This can be a safety concern for anyone using the ramp.
Another important factor is ensuring the surface of the ramp has sufficient grip, particularly in winter when conditions can be difficult. You'll need to sweep away any leaves, dirt and other debris that can obstruct the surface and cause slippage. Additionally, you'll need to apply a non-corrosive ice melt on the ramp's surface before winter arrives to prevent slipping and causing injury.
If you're planning to use your ramp throughout the winter months, you should consider purchasing wheels for traction or "snow tires" for your wheelchair. They're specifically designed to aid in tracking on uneven surfaces and snow which is why they'll be more effective than standard wheelchair tires at keeping you on the ramp. You can also use heating tape or pads to melt the snow and ice on the ramp prior to it accumulates.
