Abstract
The invention provides a drainage channel preferably formed from a sheet material, such as stainless steel. The channel has a flat bottom and upwardly extending sidewalls that form an acute angle with the bottom. A pair of shoulders extend outwardly from upper portions of the sidewalls for receiving a grate. Upper edge walls extend upwardly from outer portions of each shoulder. The exterior width of the channel at its bottom is less than the interior width or the channel between the upper edge walls, but greater than the interior channel width between the upper ends of the sidewalls. Consequently, the drainage channel can be mechanically anchored in concrete without requiring use of additional anchoring elements, and is also stackable.
Claims16
A drainage channel comprising:
- a substantially flat bottom wall;
- a pair of sidewalls extending upwardly from said bottom wall;

- and
- a pair of upper edge walls, each extending upwardly from an outer edge of one shoulder;
- the exterior width of the channel adjacent the bottom wall thereof being less than the interior width of the channel between the upper edge walls and greater than the interior width of the channel between the upper ends of said sidewalls.
