Interlocking panels and rail for an enclosure

1. A rail for an enclosure, comprising:

a horizontal leg;

a first leg connected perpendicularly to the horizontal leg and a second leg connected perpendicularly to the horizontal leg and opposing the first leg, where the first leg and the second leg form a channel;

a gusset formed between the horizontal leg and the first leg, where the gusset defines a hollow opening; and

an aperture formed in the horizontal leg, where the aperture is in communication with the hollow opening;

wherein the rail is alternatively positioned in

a first orientation, in which the channel receives a bottom of a wall of the enclosure, the horizontal leg engages and is secured to a skid or tank of the enclosure, and the hollow opening is positioned on an inside of the enclosure, and

a second orientation, in which the channel receives a top of the wall, the horizontal leg engages and is secured to a roof of the enclosure, the aperture is positioned above the hollow opening, and the hollow opening is positioned on an outside of the enclosure to act as a gutter for rain passing through the aperture and into the hollow opening.

2. The rail of claim 1 , where the gusset includes a decorative feature.

3. The rail of claim 1 , further including a notch formed in the gusset at the horizontal leg.

4. The rail of claim 1 , where the aperture is configured for receiving a fastener to secure the roof to the horizontal leg.

5. The rail of claim 4 , where the aperture includes threads for a fastener to thread into.

6. The rail of claim 1 , where the horizontal leg is thicker at a position of the aperture than at other parts of the horizontal leg.

7. The rail of claim 1 , further including an undercut feature formed in the channel between the horizontal leg and the first leg and the second leg, the undercut feature to provide clearance for the wall when the wall is inserted into the channel.

8. The rail of claim 1 , further including a notch running along the horizontal leg to provide a guide for caulk.

9. The rail of claim 1 , where the first leg includes a flange portion to support the wall.

10. The rail of claim 1 , further including a second aperture formed in the first leg.

11. The rail of claim 10 , where the second aperture includes threads for a fastener to thread into.

12. The rail of claim 1 , further including a chamfer formed in an end of at least one of the first leg and the second leg.

13. The rail of claim 1 , wherein one of the first leg and the second leg is longer than the other of the first leg and the second leg.

14. The rail of claim 1 , wherein the first leg is longer than the second leg.

15. An enclosure, comprising:

a wall formed of a construction panel and a like panel, wherein the wall has a top and a bottom, the construction panel including a first interlock member comprising a generally cylindrical bead-like member adapted to be received in a trough-like portion and a projecting lip adapted to act as a fulcrum against a first inwardly projecting member to slightly deflect a second inwardly projecting member as the construction panel is levered into interlocking engagement with the like panel; and

a rail including a horizontal leg connected perpendicularly with a vertical leg, and a gusset formed between the horizontal leg and the vertical leg and defining a hollow opening, wherein the horizontal leg includes an aperture formed in the horizontal leg, wherein the aperture is in communication with the hollow opening, wherein the rail is alternatively positioned in

a first orientation, in which the rail engages the bottom of the wall, the horizontal leg engages and is secured to a skid or tank of the enclosure, and the hollow opening is positioned on an inside of the enclosure, and

a second orientation, in which the rail engages the top of the wall, the horizontal leg engages and is secured to a roof of the enclosure, the aperture is above the hollow opening, and the hollow opening is positioned on an outside of the enclosure to act as a gutter for rain passing through the aperture and into the hollow opening.
