Abstract

A transit boarding platform panel comprising a base portion formed from a reinforced composite polymer. The base portion has a top deck and a bottom plate, a first end, a second end, a first side and second side. Between the top deck and bottom plate are a series of internal longitudinal and cross support members. The top deck has a central section and opposite end sections. Detectable warning tiles are mounted to the top surfaces of the end sections. The top surface of the central section has a slip resistant surface. Positive drainage is provided by the top deck to facilitate runoff of any precipitation and prevent standing pools of water. Positive drainage is further provided by the interface between adjacent panels utilizing a ship lap configuration with a drainage channel beneath the joint between adjacent panels.

Claims

1. A transit boarding platform panel comprising a molded base portion formed from a reinforced composite polymer, said base portion having a top deck and bottom plate, first and second opposite ends wherein one or both of said first and second ends are adjacent an edge of the transit platform, a first side and second side, and between the top deck and bottom plate a series of internal support members, wherein said top deck, bottom plate, first and second opposite ends, first side, second side and series of internal support members are molded at the same time to form an integral unit, said top deck having a detectable warning surface consisting of raised truncated domes detectable by the visually impaired in accordance with Americans with Disabilities Act (ADA):

Accessibility Guidelines for Buildings and Facilities at the ends of the panel adjacent the edge of the transit platform, wherein the first and second sides of said base portion are each provided with an interface for contacting an adjacent panel, the interface including a ship lap configuration for forming a drainage channel beneath joints formed between the adjacent panels.

2. A transit boarding platform panel according to claim 1 wherein the first side of said base portion is adapted to form a drainage channel along the joint between adjacent panels.

3. A transit boarding platform panel according to claim 2 wherein the first side of said base portion has a top section and a bottom section, said top section having a first vertical wall section having a first end adjacent said top deck and said first vertical wall section extending downwardly to a second end, a horizontal flange extending outwardly from the second end of the first vertical wall section and having an exterior edge, a second vertical wall section extends upwards from the exterior edge said horizontal flange, said second vertical wall section having a top edge and a bottom edge, a second horizontal flange having an inner and outer edge and extending outwardly from the top edge of the second vertical wall section.

4. A transit boarding platform panel according to claim 3 wherein the bottom section of said first side has third vertical wall section that depends from the outer edge of the second horizontal flange and connects to the bottom plate.

5. A transit boarding platform panel according to claim 4 wherein the second side of said base portion is adapted to overlie the drainage channel of an adjacent panel.

6. A transit boarding platform panel according to claim 5 wherein the second side of the base portion has a top section and a bottom section, said top section having a first vertical wall section extending downwardly from the top deck, a horizontal flange extends inwardly from the base of the vertical wall section, the bottom section of said second side has a second vertical wall section that depends from the inner edge of the horizontal flange and connects to the bottom plate.

7. A transit boarding platform panel according to claim 6 wherein the joint between the first and second sides of adjacent panels is adapted to be sealed to prevent moisture from getting between the panels.

8. A transit boarding platform panel according to claim 2 wherein the drainage channel is adapted to collect and direct to the edge of the platform any moisture that penetrates between panels.
