Universal base plate with tabs
Fluid runoff systems, methods, and apparatus for processing fluid runoff are provided. In one implementation, a base plate for receiving an inlet casting at a drain basin may be provided. The base plate may include a flat surface with an aperture and an outside edge surrounding the flat surface; a raised lip may surround the outside edge and a flange may extend in a horizontal direction away from the raised lip. The flange may define a flat surface for an inlet casting. The base plate may further include one or more sets of tabs located on the underside of the plate. In another implementation, a fluid runoff system may comprise an inlet casting, a base plate, a drain basin, and a pipe. The base plate may include one or more sets of tabs for connecting with the drain basin.
1. A base plate for receiving an inlet casting at a drain basin, the base plate comprising:
a plate having a flat surface with an aperture and an outside edge surrounding the flat surface, wherein the flat surface includes an underside, a topside, and one or more concentric rings comprising concentric openings through the flat surface, wherein the one or more concentric rings are configured to be cut to form a complete opening to receive the drain basin;
one or more sets of tabs located on the underside of the plate;
a raised lip surrounding the outside edge, wherein the raised lip extends upward from the outside edge; and
a flange extending in a horizontal direction away from the raised lip, wherein the flange defines a relatively flat surface to receive an inlet casting.
2. The base plate of claim 1 , wherein the one or more sets of tabs comprise a set of inside tabs and a set of outside tabs.
3. The base plate of claim 2 , wherein the set of inside tabs and the set of outside tabs project downward relative to the underside of the baseplate.
4. The base plate of claim 3 , wherein the inside tabs are arranged in a first circular pattern around the aperture and each inside tab is located a first distance equidistant from a center of the aperture.
5. The base plate of claim 2 , wherein the set of inside tabs comprises four tabs and wherein the set of outside tabs comprises four tabs.
6. The base plate of claim 4 , wherein the outside tabs are arranged in a second circular pattern around the aperture, wherein the second circular pattern is located farther away from the aperture than the first circular pattern, and each outside tab is located a second outside distance equidistant from the center of the aperture.
7. The base plate of claim 2 , wherein each tab in the set of outside tabs is located a fixed radial distance from the set of inside tabs.
8. The base plate of claim 2 , wherein each tab in the set of inside tabs is aligned with each tab in the set of outside tabs.
9. The base plate of claim 2 , wherein each tab in the set of inside tabs is not aligned with each tab in the set of outside tabs.
10. The base plate of claim 4 , wherein an inner diameter of the first circular pattern fits an outside diameter of a 24-inch basin.
11. The base plate of claim 6 , wherein an inner diameter of the second circular pattern fits an outside diameter of a 30-inch basin.
12. The base plate of claim 1 , wherein the flange includes a chamfered edge.
13. The base plate of claim 1 , wherein the base plate is comprised of ductile iron.
14. The base plate of claim 1 , wherein the flat surface includes four sides and a length of the flange on one side is longer than a length of the flange on the other sides.
15. A fluid runoff system for managing fluid runoff comprising:
an inlet casting;
a base plate for receiving the inlet casting at a drain basin, the base plate comprising:
a plate having a flat surface with an aperture and an outside edge surrounding the flat surface, wherein the flat surface includes an underside, a topside, and one or more concentric rings comprising-concentric openings through the flat surface, wherein the one or more concentric rings are configured to be cut to form a complete opening to receive the drain basin;
one or more sets of tabs located on the underside of the plate;
a raised lip surrounding the outside edge, wherein the raised lip extends upward from the outside edge; and
a flange extending in a horizontal direction away from the raised lip, wherein the flange defines a relatively flat surface to receive the inlet casting; and
the drain basin below the baseplate, the drain basin having a tubular body, the tubular body including an inner cavity, an outer surface, and a top end; and
a pipe connected to the tubular body.
16. The fluid runoff system of claim 15 , wherein the one or more sets of tabs comprise a set of inside tabs and a set of outside tabs.
17. The fluid runoff system of claim 16 , wherein the set of inside tabs and the set of outside tabs project downward relative to the underside of the baseplate.
18. The fluid runoff system of claim 17 , further comprising a reducing plate having a bottom surface and a top surface, wherein the reducing plate is located above the drain basin and below the base plate.
19. The fluid runoff system of claim 18 , wherein the top surface of the reducing plate connects with the set of outside tabs.
20. The fluid runoff system of claim 19 , wherein the bottom surface of the reducing plate connects with the top end of the drain basin.
