Abstract:

A plank () used to construct a platform such as a catwalk (C, C) extending about the exterior or interior of a building (B) includes first and second generally horizontal sections (). The second generally horizontal section of the plank extends from one side of the first section. During construction of the platform, the first section of one plank overlaps the second section of an adjacent plank. A third generally vertical section () of the plank extends generally perpendicularly from one side of the second section and includes lips () at its inner and outer ends for attaching the plank to toe boards () to secure the plank to the frames. When installed, the planks extend from a side of the building. The resulting catwalk extends either in a straight line, or is curved, depending upon the amount of overlap the first and second sections of the respective planks.
