11 Ways To Fully Redesign Your Wheelchair Ramp > 자유게시판

Wheelchair Ramp Design and Construction

A ramp for wheelchairs can be an important device to assist the person you love independently at home. However, if they aren't designed correctly, they can be dangerous to use.

ADA regulations require landings to be level at every change in direction, to avoid compound slopes. They must also have an area that is grippy for wheelchair users.

Design

The ramp design must meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can comfortably navigate the structure. For instance, the ramp's slope must not exceed a ratio of 1:12 and must have level landings at any change in direction or change in the ramp's surface. It also must be constructed from treated lumber, which is more durable and weathers precipitation far better than untreated lumber.

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

For the frame of the ramp choose treated lumber that is at minimum four inches wide. Create posts to anchor the ramp, ensuring they are at least eight feet apart and that they extend below the level of the ground. Spindles should be used to connect the posts with the railings of the ramp. This type of connection reduces the risk of a ramp operator slipping off the side.

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

Install an upper landing on the doorway to ensure electric wheelchair ramp for Van users can easily navigate the doorswing. The landing should be enough to provide at least 12-24 inches of "elbow room" on the handle side for out-swing doors. The landing for doors with in-swinging should be 58 x 60 inches in order to accommodate the threshold of the door and a wheelchair user who has to go backwards through the doorway.

Install a level landing when changing the direction of the ramp to prevent wheelchairs from having to hit their brakes into corners. A level landing is easier to move a ramp out of the path if needed, so that equipment like lawnmowers can pass beneath it.

Materials

The material used to build the ramp for wheelchairs can be either concrete, wood or aluminum. A professional ramp installer will help you select the most suitable option for your home or office. It is essential to take into consideration your budget and needs when selecting the materials for the ramp. The ramp should be simple to maintain, and it should be safe for use. Certain cities require that the ramp be paved with an anti-slip surface.

Be sure to inquire with your local government for permits before you begin building or buying any materials. Also, make sure to follow all local building codes. Incorrect construction materials or methods can result in dangerous conditions for wheelchair users. You can find current construction requirements in your local government building department library, or on the internet.

Wood ramps can be the cheapest alternative for ADA ramp materials. However they require more care. Wood ramps should be treated regularly with sealers to stop decay. Wood splinters can be a problem, and could be particularly dangerous for wheelchair users. Wood ramps can also need additional support to ensure the structure is maintained.

Concrete ramps are expensive however they are durable and long-lasting. They are heavy, which means more work is required to construct them and can make it difficult to move the ramp once it is no longer required. Concrete ramps can withstand the weight of powerful wheelchairs.

Aluminum ramps are lighter than concrete or steel however they offer the same strength and corrosion resistance. They are also cheaper than steel and iron, making them an excellent option for people on budgets. Aluminum is eco-friendly because it is a part of the earth's crust naturally and can be recycled.

The ramp's upper landing should be level or within 3 step wheelchair ramp/8 inches of the threshold of the door, allowing wheelchairs with smaller wheels to move over the ramp without getting 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 surface. The final section of the ramp should have a beveled transition to avoid an abrupt stop for wheelchairs as they exit or enter a dwelling.

Installation

A wheelchair ramp is a plane inclined ramp that can be erected as an alternative or in addition to stairs. It allows wheelchair loading ramps users as well as people who use carts or strollers to access areas that are otherwise difficult to access.

When choosing a wheelchair access ramp, there are many factors to consider, including the location, height, and price. A ramp should be situated near the door as possible to help prevent unnecessary journeys. It should also be placed at an angle that is easy to navigate by the person using it. It should also be fixed to the ground and free of obstructions, such as the trees or cars parked.

ADA regulations require that ramps are equipped with handrails either side. These rails should be at 36 inches apart and have the gripping surface rounded or smooth. They must also be attached to the edge of the ramp and extend 12 inches beyond the ramp. If a ramp has switchbacks or an L-shaped layout, handrails must be continuous between the ramp's runs.

The length of the ramp is determined by the slope. However there are common ramp types that can be used for most situations. For instance the threshold ramp is right on the edge of a curb or the threshold of a doorway, while supportec portable wheelchair ramp ramps can be moved from one place to another and are available in many different sizes. Modular aluminum ramps can also be constructed on-site. These ramps are usually used in commercial or public areas and are usually longer.

If you are considering a permanent ramp, be sure to check with the building department of your city to see if you need permits. It's recommended to speak with a mobility specialist to determine which kind ramp will be the most suitable for your needs and the space you have. In certain cases the installation of an ongoing ramp could boost the value of your home.

Maintenance

It is crucial to maintain your wheelchair ramp, especially if it will be used often. You'll need to conduct regular inspections and address any structural issues as they arise. This will ensure that the ramp complies all ADA requirements, and is safe for users.

Regularly cleaning wooden ramps is necessary to get rid of dirt and other debris that could hinder access. Keep the ramp clean to avoid moisture from accumulating under the surface. This can cause decay. The wood preservatives or stains will only work when the ramp has been thoroughly cleaned before application.

Wheelchair ramps can be more challenging to maintain than other types of ramps because they are more prone to wear and tear. The most important thing is to ensure that you have the appropriate tools for the job. To make sure that all fixings are secure and tight, you will need a good set of screwdrivers as well as gauge spanners. It's also worth regularly inspecting the handrails to ensure they are in good shape and have no signs of corrosion or damage. As time passes, and with repeated usage, it's possible that some bolts or fittings that are anchored the handrails to come loose. This can be an issue for anyone who uses the ramp.

Another important aspect is to ensure the surface of the ramp has sufficient grip, particularly during winter when conditions may be difficult. You will need to sweep away any dirt, leaves or other debris that might block and cause slippage. Additionally, you'll need to apply an ice melt that is not corrosive to the ramp's surface before winter arrives to prevent slipping and causing injury.

Consider purchasing "snow tires" or traction wheels for your wheelchair if you plan to use it throughout the winter. These are specially designed to provide better tracking on uneven surfaces and snow which is why they'll be more efficient than standard wheelchair tires at helping you stay on the ramp. You can also use heating tape or pads to melt the ice and snow on the ramp before it builds up.
