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. In the preferred embodiment the slip resistant surface consists of a non-slip walking surface coating applied to the top deck. The slip resistant coating should be resistant to the effects of ultraviolet radiation, temperature changes and corrosive elements such as acids, alkalis, salts, phosphates, organic chemicals and solvents such as mineral spirits, gasoline etc. It should also preferably be sufficiently hard to protect against abrasion, chipping, scratching or marring. Positive drainage is provided by the top deck being typically symmetrical about the mid-point line tapering from the mid-point to the ends of the panel 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 base portion formed from a reinforced composite polymer, said base portion having a top deck and bottom plate, first and second opposite ends, a first side and second side, and between the top deck and bottom plate a series of internal longitudinal and cross support members, said top deck having a central section and opposite end sections, each of said central section and opposite end sections having a top surface, detectable warning tiles mounted to the top surfaces of the end sections, said warning tiles detectable by the visually impaired and a non-slip monolitic walking surface applied to the top surface of the central section, 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 of 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 to form a drainage channel to provide positive drainage between adjacent panels.

2. A transit boarding platform panel according to claim 1 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.

3. A transit boarding platform panel according to claim 2 wherein the second side of said base portion is adapted to overlie the drainage channel of an adjacent panel.

4. A transit boarding platform panel according to claim 1 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.

5. A transit boarding platform panel according to claim 4 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.

6. A transit boarding platform panel according to claim 1 wherein the drainage channel is adapted to collect and direct to the edge of the platform moisture that penetrates between panels.

7. A transit boarding platform panel according to claim 1 wherein the slip resistant walking surface is resistant to the effects of corrosive elements selected from the group consisting of acids, alkalis, salts, phosphates, organic chemicals and solvents.

8. A transit boarding platform panel according to claim 1 wherein one or more drip holes are provided in the bottom plate to eliminate moisture or condensation from within the base portion.

9. A transit boarding platform panel according to claim 1 wherein the top deck is symmetrical about its mid-point line tapering from the mid-point line to the ends of the panel.
