Ramp Construction


Here is the coping after the ramp was completed. Sitting perfectly and secure between decking and masonite.

Here is the layout of the 4 quarter pipes and the 2 flat sections. 2x4s used in the flats and 2x6s used in the transitions.
Here is the genius design of Jeff and Jim. This is when you need some nice construction gear. Its just not possible with a skill saw. There was another 2x6 placed behind these two studs but wasn't cut at the angle (you can see the screws on the side holding it).
Here is our first step. The transition was a 7'2" radius and is 3'8.5" tall (we just cut the full plywood sheet).

Here you see the thread from the u-bolt (clothesline bolt) coming out of the 2x6. We drilled 6 holes in each coping (2 3/8 inch Outer diameter used black pipe) and then stuck the hook end of the u-bolt in the holes. Once we drilled the holes in the 2x6 we just stuck the threads right through. On this side we placed a large square washer, a large round washer, a locking washer, and two nuts. Boo-yah. The coping isn't going anywhere.
The decking is beveled to meet the coping perfectly.

We placed the first two layers of 3/8 inch plywood horizontally on the ramp and made sure every seam had at least one 2x6 underneath it. We offset the second layer of plywood to make sure the seams did not double up.
Here you can see the underside of the decking. 2x6 and 3/4 inch plywood. You can also see that the entire ramp is placed on 12x12 concrete blocks.
The finished product.
