The only painted turtles that can go easily into a 55 gallon are Southerns. Eastern and Western just get too big for a 55 gallon tank. Also bricks take up too much swimming space. You are much better off just buying a turtle dock, its easier and will not cost much more than doing it yourself. I have used them and use them now and they are perfect. The other problem with the bricks is them sitting on rough surface will cause small cuts which in water can lead to infection and death.
The other problem with cork bark is it expands as the water is absorbed into it. If you wedge it too tightly you could break the seals on the aquarium. I have heard of it happening and for me its just not worth it.
If you wanted to you could mimic the turtle dock and make one yourself with cork bark. Just use two bars with suction cups on the each end and drill holes into the cork bark so it can float and move up and down with evaporation.
The problem with using something that does not go up and down with the evaporation is you have to have the water level perfect. It cannot be above the bricks, turtles have to be able to get out of the water completely to let their shells dry off. If they do not they will get infections and fungus growth. If you set it too low they will not be able to get out and bask.
Not only do you want one place for them to get out of the water but you will want two. One on a basking spot and one so they can get out of the water and not bask if they do not want to.
Here is my setup for an example:
