ABSTRACT:
An elevated walkway platform comprising at least one elongated platform module positioned in a generally horizontal attitude and being supported above a work area. The platform module comprises a substantially flat deck having side walls or toe boards extending upwardly from the opposite sides thereof. A flange extends horizontally outwardly from the upper end of each of the toe boards. A plurality of transversely extending strengthening ribs are molded integrally with the module and are positioned beneath the deck for strengthening purposes. A pair of longitudinally extending strengthening ribs may also be provided at the underside of the deck at the opposite sides thereof. The strengthening ribs are filled with a rigid foam material. The module is also provided with handrail post supports positioned at the exterior surface of the toe boards and which are adapted to receive a handrail post therein. The entire module is constructed of a one-piece, molded plastic material reinforced with fiberglass. The configuration of the deck, toe boards, flanges, and the handrail posts of the handrail assembly inserted into the post supports causes the platform to act as a truss to further strengthen the entire structure.
