Abstract
A disclosed corrugated end cap includes a corrugated frame having one or more corrugations defined by one or more sets of alternating peaks and valleys. The end cap also includes one or more ribs disposed in one or more of the valleys and one or more valley reinforcements disposed in the valleys and running over a top surface of the corrugated frame. For example, the one or more ribs may be configured to increase a resistance of the frame to bending. Additionally or alternatively, the top surface, a front surface, and a rear of the corrugated frame surround a recess configured to receive latch ridges from a stormwater chamber.
Claims21
A stormwater system, comprising:
- an end cap configured to attach to an end of a chamber body to form a lateral wall of a stormwater chamber configured to contain stormwater and defined by the chamber body and the end cap, the end cap comprising:
- a base;
- a frame;
- one or more corrugations defined by one or more sets of alternating peaks and valleys emanating from the base and up to a lateral surface of the frame, wherein the peaks and valleys have a curvature between the base and the frame, thereby forming a contoured outer surface of the end cap;
- one or more ribs disposed in one or more of the valleys and configured to increase a resistance of the frame to bending;
- and
- one or more valley reinforcements disposed down a center axis of the valleys and running over a top surface of the frame.
A stormwater system, comprising:
- an end cap configured to attach to an end of a chamber body to form a lateral wall of a stormwater chamber configured to contain stormwater and defined by the chamber body and the end cap, the end cap comprising:
- a base;
- a frame;
- one or more corrugations defined by one or more sets of alternating peaks and valleys emanating from the base and up to a lateral surface of the frame, wherein the peaks and valleys have a curvature between the base and the frame, thereby forming a contoured outer surface of the end cap;
- one or more ribs disposed in one or more of the valleys on an exterior of the end cap that faces away from the chamber body and configured to increase a resistance of the frame to bending;
- and
- one or more valley reinforcements in the valleys and running over a top surface of the frame,
- one or more additional ribs disposed on an interior of the end cap that faces towards the chamber body,
- wherein the one or more ribs are disposed at an angle relative to corresponding one or more of the peaks and the one or more ribs are positioned at different diameter positions based on dimensions of a pipe configured to fit into the end cap.
A stormwater system, comprising:
- an end cap configured to attach to an end of a chamber body to form a lateral wall of a stormwater chamber configured to contain stormwater and defined by the chamber body and the end cap, the end cap comprising:
- a base;
- a frame;
- one or more corrugations defined by one or more sets of alternating peaks and valleys emanating from the base and up to a lateral surface of the frame, wherein the peaks and valleys have a curvature between the base and the frame, thereby forming a contoured outer surface of the end cap;
- one or more ribs disposed in one or more of the valleys;
- and
- one or more valley reinforcements disposed in the valleys and running over a top surface and onto a rear surface of the frame,
- wherein the top surface, a front surface, and a rear of the frame surround a recess configured to receive latch ridges from a stormwater chamber.
