Wheelchair Ramp Design and Construction

A ramp for wheelchairs is an important device to aid a loved one live more independently at home. If not designed correctly, they are unsafe to use.

ADA regulations require level landings at any changes in direction to avoid compound slopes. They also require a surface that is gripping for wheelchair ramps for doorways users.

Design

The ramp design should meet the Americans with Disabilities Act standards so that wheelchairs are able to navigate the structure easily. The ramp slope can't exceed a ratio of 1:12, and the landings have to be level at any change of direction or change in the ramp surface. It should also be constructed using treated lumber which is more durable than untreated lumber and can weather precipitation better.

The ramp's top and bottom must be free of obstacles, such as trees or bushes, as well as other structures which could interfere with the safety of the user. Additionally, the ramp's surface must be hard and non-slip. Certain municipalities require an anti-slip surface running along the entire length of the ramp.

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

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

Install an upper landing on the doorway to ensure the wheelchair-bound occupants are able to easily maneuver the doorswing. This landing should provide 12 to 24 inches on the handle side of out-swinging doors. For doors with in-swing, the landing must be at minimum 58 by 60 inches to allow for the threshold of the door and the person in wheelchair who must walk backwards through the doorway.

Install a level landing whenever you change in the direction of the ramp to prevent the requirement for wheelchairs to step on their brakes while turning corners. A level landing makes it easier to move a ramp out of the path if needed, so that equipment like lawnmowers can be able to pass underneath it.

Materials

Aluminium, concrete, or wood can be used to build ramps for wheelchairs. A professional ramp installer can help you select the most suitable option for your office or home. When choosing the material to use for the ramp, it's crucial to consider your budget and requirements. The ramp should be Aidapt Easy Edge Threshold Ramp - 460x540mm Mobility Scooters to maintain, and it should be safe for use. Some cities require that the ramp be paved with an anti-slip surface.

Before you purchase any material or begin building, be sure that you have the required permits from your local government, and that you comply with all building codes in your area. Utilizing the wrong materials or construction methods can result in dangerous conditions for wheelchair users. You can get the most up-to-date information about construction regulations at your local building department office or library, or on the internet.

Wood ramps are often the least expensive choice of ADA ramp materials, but they require more maintenance than other options. The wood ramp's surface need to be regularly treated with a sealer to avoid rot and warping. Wood can splinter and be hazardous for those using wheelchairs. Wood ramps might require additional support to ensure the structure remains upright and stable.

Concrete ramps can be costly however they are durable and long lasting. They are heavy, which means more work is required to construct ramps and may make it difficult to move the ramp once no longer needed. Concrete ramps can withstand the weight of large power wheelchairs.

Aluminum ramps are less heavy and less expensive than concrete or steel. They also have the same durability, strength, and resistance to corrosion. They are also more affordable than steel and iron, making them an excellent option for people on a tight budget. Aluminum is also eco-friendly as it is found naturally in the Earth's crust, and can be recycled.

The ramp's upper landing needs to be level, or within 3/8 inches of the threshold of the door in order for wheelchairs with smaller wheels to move across the ramp without getting stuck. Ramps that have gaps greater than this will not be able to meet ADA standards. Also, ensure that the ramp transitions smoothly between the upper landing and the ground. The last section of the ramp should be a beveled transitions to avoid an abrupt stop for wheelchairs when they exit or enter an apartment.

Installation

A wheelchair ramp is an inclined plane that is erected on top of or in place of steps. It allows wheelchair users, as well as people who use carts or strollers to get into areas that are otherwise difficult to access.

There are several considerations when selecting a ramp for wheelchairs that should be considered, including the height, location and cost. The ramp should be located close to the door to prevent unnecessary traveling. It should also be positioned at an angle that is easily accessed by the person who is using it. It should be securely fixed to the floor and free of any obstructions such as car parks, shrubs or other obstacles.

ADA regulations require that ramps must have handrails either side. The rails must be at least 36" apart and have 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 is equipped with switchesbacks or an L-shaped layout handrails must be in continuous use between the ramp's edges.

The length of the ramp is determined by its incline. However, there are some common ramp types that can be used in all situations. A threshold ramp, for instance, sits flush against the curb's lip or threshold of the doorway. Portable ramps are, however they can be moved to another place and come in a variety of sizes. There are also modular aluminum ramps that can be assembled on the spot. These ramps are usually employed in public or commercial areas, and tend to be longer.

If you're thinking of a permanent ramp, be sure you contact the building department of your city to determine if you'll need permits. It's also a good idea to consult with a mobility expert to determine what kind of ramp is best suited to 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 important to keep your ramp for wheelchairs in good condition, especially if it will be used often. You'll need to conduct regular inspections, and fix any structural issues that occur. This will ensure that the ramp complies all ADA requirements and is safe for users.

Regularly cleaning wooden ramps is necessary to remove debris and dirt that may hinder access. Keep the ramp clean to avoid moisture from accumulating under the surface. This could cause rot. The wood preservatives or stains can only be effective if the ramp has been thoroughly cleaned prior to applying.

Wheelchair ramps are more difficult to maintain than other ramps due to the fact that they are more susceptible to wear and tear. The most important thing to do is ensure you have the proper tools for the job. To make sure that all fixings are secure and tight you'll need an appropriate set of screwdrivers and gauge spanners. You should also regularly inspect the handrails for signs damage or corrosion. It's possible that over time, with repeated usage and use, the fittings and bolts which hold the handrails in place may loosen and cause a major safety concern for those who use the ramp.

Another crucial aspect is to ensure that the ramp's surface has enough grip, especially in winter when conditions can be difficult. You'll need to sweep away any leaves, dirt and other debris that could block the surface and cause slippage. It is also recommended to apply an ice melt that is non-corrosive to the ramp's surface to avoid injuries and slipping.

Think about purchasing "snow tires" or traction wheels for your wheelchair if you plan to use it throughout the winter. They're specifically designed to offer better tracking on uneven and snowy surfaces, so they'll be more effective than standard wheelchair tires at aiding you to stay on the ramp. You can also use heating tape or pads to melt the snow and ice on the ramp before it accumulates.
