wheelchair ramp for van Ramp Design and Construction
A wheelchair ramp is a vital tool for helping a loved one to live independently in their home. If they are not designed properly, they are dangerous to use.
ADA regulations require landings to be level at every change in direction, so as to avoid compound slopes. They also must provide a gripping surface for wheelchair users.
Design
The ramp design should meet the Americans with Disabilities Act standards to allow wheelchairs to navigate the structure easily. The ramp’s slope must not exceed a 1:12 ratio, and the landings have to be level at any change of direction or change in the ramp surface. It must also be constructed out of treated lumber, which is more durable and can withstand precipitation much better than untreated lumber.
The ramp’s top and bottom should be free of any obstacles, such as trees or bushes, as well as other structures that could hinder the safety of the user. In addition, the ramp’s surface must be smooth and non-slip. Some municipalities require that the entire ramp be coated with an anti-slip surface.
For the ramp frame choose treated lumber that is at least 4 inches wide. Create posts to anchor the ramp, making sure they are at least eight feet apart, and that they extend above the ground level. Spindles are the best way to join the posts with the railings of the ramp. This type of connection is preferred since it decreases the chance of an operator of the ramp falling off the side of the ramp.
Then, you can build the ramp’s frame with beams of 2 by 4 inches in size, and Joists that are at least 16 inches long. Make sure that the joists stand a minimum of 18 inches above ground level and that they are secured with Joist hangers, which are nails that hold the inside of the joists and portable wheelchair ramp for van prevent them from slipping off the ground. Attach the ramp decking using a framing nailer.
Create an upper landing in the doorway to enable wheelchair users to control the doorswing with ease. This landing should provide 12 to 24 inches on the handle side of the doors that swing out. The landing for in-swinging doors should be 58 x 60 in order to accommodate the threshold of the door as well as wheelchair users who need to reverse through the doorway.
Install a level landing when you change the direction of the ramp to stop wheelchairs from having their brakes at corners. A level landing makes it simpler to remove a ramp of the path if needed, so that lawnmowers and other equipment can move under it.
Materials
The material used to construct ramps for wheelchairs could be either concrete, wood or aluminum. A professional ramp installer can help you choose the best option for your home or office. It is crucial to think about your specific needs and budget when selecting the materials for the ramp. The ramp must also be simple to maintain and safe for use. Certain cities require that the ramp be paved with a non slip wheelchair ramp-slip surface.
Before you purchase any building materials or begin construction, make sure that you have the necessary permits from your local authority and that you comply with all building codes within your area. Using the wrong materials or construction methods could result in hazardous conditions for wheelchair users. You can find current construction requirements in your local building department or library, or on the internet.
Wood ramps are the most affordable alternative for ADA ramp materials. However they require more care. The surface of wood ramps should be treated regularly with a sealer to prevent rot and warping. Wood can splinter, which can be especially hazardous for people in wheelchairs. Wood ramps might also require additional support to keep the structure in place and stable.
Concrete ramps are extremely durable and long-lasting, but they can be costly. They are also heavy, which requires more labor to install and makes moving the ramp once it’s no longer required difficult. Concrete ramps can handle the weight of heavy power wheelchairs.
Aluminum ramps weigh less than steel or concrete, but they have the same strength and resistance to corrosion. They are also less expensive than steel and iron which makes them a great option for those with budgets. Aluminum is environmentally friendly because it is a part of the earth’s crust naturally, and can be recycled.
The ramp’s upper landing needs to 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 becoming stuck. Ramps that have a gap greater than this do not comply with ADA standards. It is also important to ensure that the ramp transitions smoothly from the upper landing to the ground. The ramp’s final section should be curved to ensure that wheelchairs don’t stop abruptly when entering or leaving a house.
Installation
A ramp for wheelchairs is an inclined plane that is erected in addition to or in lieu of stairs. It allows wheelchair users and those who use strollers or carts to reach areas that would otherwise be difficult to access.
When choosing a wheelchair access ramp, there are numerous factors to consider, such as the location, height, and price. Ideally, a ramp should be located as close to the door as is possible to help prevent unnecessary transportation. It should be set at a level that is easy to navigate by the person using it. It should also be properly fixed to the ground and clear of obstructions, such as shrubbery or parked cars.
ADA regulations require that ramps have handrails either side. The rails must be at least 36 inches apart and have a gripping surface that is smooth or rounded. They must also be attached to the edge of the ramp, and extend 12 inches over it. Handrails must be continuous when the ramp is designed with switchbacks or in an L-shaped layout.
The length of a ramp depends on the incline, but there are several basic ramps that are suitable for most situations. A threshold ramp, for example is a ramp that is flush with the curb’s lip or threshold of the doorway. Portable ramps are, however they can be moved to a new location and are available in different sizes. There are also aluminum ramps that are modular that can be built on site. These ramps are usually employed in public or commercial areas and are typically longer.
If you are considering a permanent ramp, make sure you contact the building department of your city to see if you need permits. It is also advisable to speak with a mobility specialist about the kind of ramp that will work best for your needs and the space. In some cases, installing permanent ramps can improve the value of your home.
Maintenance
It’s crucial to ensure your ramp for wheelchairs is maintained, especially if will be using it often. It is essential to conduct regular inspections and deal with any structural issues as they occur. This will ensure that the ramp complies all ADA requirements, and is safe for users.
Wooden ramps require frequent cleaning to remove debris and dirt that could block access. Keep the ramp spotless to stop moisture from accumulating beneath the surface. This can lead to the onset of rot. The wood preservatives or stains will only work when the ramp has been thoroughly cleaned before application.
Wheelchair ramps are more difficult to maintain than other ramps because they are more prone to wear and tear. It is important to have the right tools. A good set of gauge spanners as well as screwdrivers is essential for making sure all fixings are secure and secure. It’s also worth regularly inspecting the handrails to ensure they are in a good condition and have no signs of corrosion or damage. It’s possible that, over time, as they are used repeatedly, some of the bolts and fittings that hold the handrails on may loosen and cause a major safety concern for people who use the ramp.
It is also essential to make sure that the surface of the ramp is grippy enough, especially in winter when the conditions can be difficult. You’ll need to sweep 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 to the ramp surface to avoid slips and injuries.
Think about buying “snow tires” or traction wheels for your wheelchair threshold ramps if you intend to use it during the winter. These wheels are made to track better on slippery and snowy surfaces. They will help you remain on your ramp more effectively than regular wheelchair tires. You can also utilize heating pads or tape to melt the snow and ice on the ramp prior to it accumulates.
