wheelchair ramp (led-5i8l419h33N.net) Design and Construction

A wheelchair ramp is an important tool for helping your loved ones live at home independently. If they are not designed properly they could be unsafe to use.

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

Design

The ramp design must meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can effortlessly navigate the structure. For instance, the ramp's slope must not exceed a ratio of 1:12 and must have landings that are level upon any angle or shift in the ramp's surface. It must be constructed of treated lumber, which is more durable than untreated and is able to withstand rain better.

The sides and top of the ramp need to be clear of obstacles such as bushes, trees or other structures that may hinder the safe passage of the ramp's user. Additionally the surface of the ramp must be smooth and non-slip. Some municipalities require an anti-slip running surface on the ramp's entire length.

Use treated lumber at minimum 4 inches in width for the ramp frame. To secure the ramp, build posts that are at least 8 feet apart and extend below the level of the ground. The posts should be connected with the ramp's railings by using spindles. This type of connection decreases the chance of a ramp operator slipping off the ramp.

Next, build the ramp's frame using joists that are at least 16 inches long and beams of 2 by 4 inches. The joists must be at least 18 inches above ground and secured using Joist hangings, which are nails that fit within the joists, preventing them from sliding. Attach the ramp decking using a framing nailer.

Add an upper landing to the doorway so that wheelchair users can easily navigate the doorswing. The landing should be wide enough to give at least 12 to 24 inches of "elbow room" on the handle side for out-swing doors. The landing for doors that are in-swinging must be 58 by 60 inches in order to accommodate the threshold of the door as well as a wheelchair user who has to reverse through the doorway.

Install an elevated landing at every change in ramp direction to avoid the necessity for wheelchairs to hit on their brakes while turning corners. A level landing makes it simpler to move a ramp out of the way if required, so that equipment such as lawnmowers can pass beneath it.

Materials

The material used to build a rubber wheelchair ramps threshold ramps ramp can be either concrete, wood or aluminum. A professional ramp installation company can help you decide the best option for your home or business. It is crucial to think about your budget and needs when selecting the materials for the ramp. The ramp must also be easy to maintain and safe for use. Certain cities require that the ramp be paved with an anti-slip surface.

Before you purchase any materials or begin construction, make sure that you have the necessary 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 wheelchair users. You can find the most current construction regulations in your local building department of the government, library or on the internet.

Wood ramps are usually the least expensive of ADA ramp materials, however they require more maintenance than other alternatives. The wood ramp's surface must be regularly treated with a sealer to avoid rot and warping. Wood can splinter and be hazardous for those using wheelchairs. Wood ramps can also need extra support to ensure the structure is maintained.

Concrete ramps are extremely durable and last for a long time, but they can be expensive. They are also heavy, which means more work to construct and makes moving the ramp once it's no longer needed difficult. Concrete ramps are strong enough to withstand the weight of power wheelchairs.

Aluminum ramps are lighter and less expensive than steel or concrete. They also have the same strength, durability and resistance to corrosion. They are also less expensive than iron and steel, making them an excellent alternative for those on an extremely tight budget. Aluminum is also eco-friendly, 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 threshold to allow the front wheels of smaller wheelchairs to move over it without getting stuck. Ramps with a gap larger than this won't meet ADA standards. Also, ensure that the ramp transitions smoothly from the upper landing to the ground surface. The last section of the ramp should have a beveled transition to avoid an abrupt stop for wheelchairs as they enter or exit the dwelling.

Installation

A wheelchair ramp is an inclined plane that is installed as an addition or in place of steps. It allows wheelchair users and those who use strollers or carts to get into areas that would otherwise be difficult to access.

When choosing a wheelchair accessible ramp, there are numerous aspects to take into consideration, including the location, height and price. The ramp should be located close to the door to prevent unnecessary travel. It should also be placed at an angle that is easily accessed by the person who is using it. It should also be properly secured to the ground and clear of obstructions, like trees or parked cars.

ADA regulations require ramps to have handrails on either side. The rails must be at least 36 inches apart and have a gripping surface that is rounded or smooth. They must also be anchored to the edge of the ramp, and extend 12 inches over it. If a ramp has switchbacks or an L-shaped layout handrails should be a continuous length between the ramp's edges.

The length of a ramp is contingent on the incline, however there are several common ramp types that can be used in most situations. For instance the threshold ramp is placed flush along the lip of a curb, or the threshold of a doorway, while portable ramps can be moved from one location to another and come in a variety of sizes. There are also aluminum ramps with modular design that can be built on the spot. They are typically used for public or commercial spaces and are usually longer than the threshold and ramps that are portable.

If you are considering a permanent ramp, be sure to check with your city's building department to determine if you require permits. You should also speak to an expert in mobility to determine the type of ramp that is best for your needs and space. In some cases installing permanent ramps could boost the value of your home.

Maintenance

It's crucial to ensure your wheelchair ramp is well maintained, especially if you are going to use it often. You'll need to perform regular inspections, and fix any structural problems as they arise. This will ensure that the ramp is in compliance with all ADA requirements and is safe for the users.

Regularly cleaning wooden ramps is necessary to get rid of dirt and other debris that may hinder access. Keeping the ramp clean will also prevent moisture from trapping under the surface and leading to decay. Wood preservatives and stains only work effectively when the ramp is clean prior to application.

Wheelchair ramps are more difficult to maintain than other ramps due to the fact that they are more likely wear and tear. The most important thing to do is ensure that you have the right tools for the job. To make sure that all fixings are secure and tight you'll need a good set of screwdrivers as well as gauge spanners. It's also important to check regularly the handrails to make sure they are in good working order and have no signs of corrosion or damage. With time and repeated use, it's possible for the bolts or fittings that are anchored the handrails to come loose. This can be an unsafe situation for anyone using the ramp.

Another important factor is ensuring the ramp's surface has sufficient grip, particularly in winter when conditions can be challenging. You'll need to clean away any dirt, leaves and other debris that can obstruct 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.

If you're planning on using your ramp all winter months, you should consider purchasing wheels for traction, or "snow tires" for your wheelchair. These wheels are made to be more efficient on slippery and snowy surfaces. They will help you stay on your ramp more effectively than normal wheelchair tires. You can also utilize heating pads or tape to melt snow and ice on the ramp before it builds up.
