The Wheelchair Ramp Success Story You'll Never Believe > 자유게시판

Wheelchair Ramp Design and Construction

A wheelchair ramp is a crucial tool in helping a loved one live at home independently. If not designed correctly, they are dangerous to use.

ADA regulations require landings to be level at any shift in direction to avoid compound slopes. They also require an accessible surface for wheelchair users.

Design

The ramp's design has to meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs easily navigate the structure. The ramp's slope must not exceed a ratio of 1:12, and the landings have to be level at any change of direction or shift on the ramp surface. It must also be constructed using treated lumber which is more durable than untreated lumber and is able to withstand rain better.

The top and bottom of the ramp need to be free of obstacles such as bushes, trees or other structures that may interfere with the safe passage of the ramp's user. The ramp's surface must be non-slip and hard. Some municipalities require that the entire ramp be covered with an anti-slip surface.

For the frame of the ramp Choose treated lumber that is at least four inches wide. 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 connect the posts with the ramp's railings. This type of connection is preferred since it reduces the risk of a ramp operator falling off the side of the ramp.

Then, build the ramp's frame using beams that measure 2 by 4 inches in size and Joists that are at least 16 inches long. Make sure that the joists are a minimum of 18 inches above the ground and that they're secured with hangers for joists, which are nails that grip the inside of the joists and prevent them from slipping off the ground. Attach the ramp decking using a framing nailer.

Add an upper landing to the doorway so that wheelchair occupants can easily manage the doorswing. The landing should be wide enough to allow at least 12 to 24 inches of "elbow space" on the handle side for out-swing doors. The landing for in-swinging doors must be 58 by 60 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 you change the direction of the ramp, to avoid wheelchairs from having to hit their brakes at corners. A level landing makes it easier to move the ramp away from the way if necessary, so that lawnmowers or other equipment can slide under it.

Materials

The materials used to construct a wheelchair ramp can be wood, concrete or aluminum. A professional ramp installation company can assist you in deciding which is best for your home or business. When choosing the material to use for the ramp, it is crucial to consider your budget and the specific requirements. The ramp should be simple to maintain and must be safe to use. Some cities require that the ramp be paved with an anti-slip surface.

Before you purchase any material or begin building, be sure you have the required permits from your local government, and that you follow all building codes within your area. The wrong materials or construction techniques can create dangerous conditions for wheelchair users. You can find current construction regulations in your local building department library, or on the internet.

Wood ramps are the cheapest alternative for ADA ramp materials. However they require more care. The surface of wood ramps should be treated regularly with a sealer to avoid rot and warping. Wood splinters can be a problem, and is particularly hazardous for wheelchair users. Wood ramps may also require extra support to maintain the structure.

Concrete ramps are extremely durable and last for a long time However, they can be costly. They are heavy, which means that more labor is required to install ramps and may make it difficult to move the ramp after it is no longer needed. Concrete ramps can handle the weight of heavy power wheelchairs.

Aluminum ramps are lighter and less expensive than concrete or steel. They also have the same durability, strength and corrosion resistance. They are also cheaper than steel and iron which makes them a great alternative for those on an extremely tight budget. Aluminum is also environmentally friendly because it is naturally present in the Earth's crust, and can be recycled.

The upper landing of the ramp should be level or within 3/8 inch of the threshold to allow the front wheels of smaller wheelchairs to pass over it without getting stuck. Ramps with gaps that is larger than this will not meet ADA standards. Also, ensure that the ramp flows smoothly from the upper landing to the ground surface. The final section of the ramp should have an angled transition to prevent an abrupt stop for wheelchairs as they enter or leave an apartment.

Installation

A ramp for wheelchairs is an inclined plane that is installed as an addition or in place of stairs. It allows wheelchair users, and those who use strollers or carts to access areas that are otherwise difficult to access.

When choosing a wheelchair accessible ramp, there are numerous aspects to take into consideration, including the location, height and cost. A ramp should be located close to the door threshold ramps for wheelchairs as is possible to avoid unnecessary transportation. 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 secured to the ground and clear of obstructions like shrubbery 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 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 must be in continuous use between the ramp's runs.

The length of the ramp is determined by its incline. However there are a few standard ramp types which can be used in all situations. A threshold ramp, for instance is a ramp that is flush with the curb ramp for wheelchair's lip or threshold of the doorway. Portable ramps, however they can be moved to a different location and are available in a variety of sizes. Modular aluminum ramps can also be built on-site. These are often used for public or commercial spaces and are usually longer than the threshold and portable wheelchair ramps for home ramps.

Check with your city's construction department to determine the need for a permit for a permanent wheelchair ramps for homes (writes in the official Aeust blog) ramp. You should also speak to an expert in mobility to determine the type of ramp that will work best for your needs and space. In certain cases installing an all-weather ramp can increase the resale value of your home.

Maintenance

It is essential to keep your ramp for wheelchairs in good condition especially if it will be used frequently. You'll need to conduct regular inspections and deal with any structural issues as they arise. This will ensure that the ramp is compliant with all ADA requirements and is safe for all users.

Wooden ramps require regular maintenance to remove debris and dirt that can obstruct access. Keep the ramp spotless to stop moisture from accumulating under the surface. This could cause rot. The wood preservatives or stains only work when the ramp has been thoroughly cleaned prior to application.

Wheelchair ramps are more difficult to maintain than other ramps as they are more prone to wear and tear. The most important thing is to make sure you have the appropriate tools to complete the task. To ensure that all fixings are secure and secure you'll need an appropriate set of screwdrivers as well as gauge spanners. It's also important to check regularly the handrails to ensure they are in a good condition and do not show signs of damage or corrosion. With time and repeated use, it's possible for some of the bolts or fittings on the handrails to come loose. This could pose a safety concern for anyone who is using the ramp.

It is also essential to ensure that the surface the ramp is sufficiently grippy especially in winter, when conditions can be challenging. You will need to sweep up any dirt, leaves or other debris that might block and cause slippage. Additionally, you'll need to apply a non-corrosive ice melt to the ramp's surface before winter arrives to avoid slips and injury.

If you're planning on using your ramp during winter, consider investing in wheels for traction or "snow tires" for your wheelchair. These wheels are designed to be more efficient on snowy surfaces and uneven surfaces. They can help you stay on your ramp longer than normal wheelchair tires. Alternatively, you can place heating pads or tape along the ramp's surface to melt ice and snow before it gets accumulated.
