Bridge platform
First Claim
1. A method for installing a platform below the deck of a bridge for supporting persons performing work on the bridge and for collecting debris resulting from the work, said method comprising the steps of:
- a) providing a plurality of cables;
b) providing a pair of assemblies each having components for installation on a bridge structure;
c) installing said pair of assemblies on a corresponding pair of spaced-apart bridge structures at locations below the deck of the bridge;
d) connecting said cables to said assemblies so as to secure the cables to the bridge so that they extend along the bridge and in spaced relation to each other and in a plane substantially parallel to the deck at a distance below the portion of the bridge upon which work is to be performed;
e) providing a plurality of flooring sections each comprising corrugated elongated rectangular decking panels wherein the corrugations extend along the length of the panel and each flooring section having at least one opening therein;
f) placing the flooring sections on the cables with the corrugations extending transversely of the cables and with the sections in end-to-end and side-to-side contacting relation to each other; and
g) fastening the flooring section to the cables by means of releasable connector assemblies each engaging the flooring sections and a corresponding one of the cables by placing a first part of a connector assembly so that a portion thereof is in engagement with the upper surface of the flooring section and another portion thereof is in engagement with the cable through an opening in the flooring section, placing a second part of the connector assembly in engagement with the upper surface of the flooring section and releasably connecting the first and second parts together so that each individual flooring section can be removed to allow access through the flooring.

Abstract
A bridge platform and method of erecting the same wherein a plurality of cables extend longitudinally of the bridge in spaced relation below the deck or roadway and steel support structure of the bridge, which cables are supported at opposite ends by the spaced-apart vertical piers of the bridge, and wherein a plurality of platform flooring panels or sections are supported on the cables, extend laterally of the bridge, are arranged side-by-side along the length of the bridge between the piers and are removably secured to the cables. The cables are attached to the bridge piers by compression clamp structures. The platform flooring sections comprise elongated rectangular corrugated decking panels and are arranged in end-to-end overlapping relation transversely of the bridge, side-to-side overlapping relation longitudinally along the bridge and with the corrugations extending transversely of the cables. The corrugations maximize the strength-to-weight ratio of the platform flooring and provide recesses or receptacles to contain debris and facilitate its collection and removal. Each of the platform flooring sections is releasably connected at spaced locations to the supporting cables on which it rests. This is provided by connector assemblies each comprising a first part which engages the upper surface of the flooring section and the cable and a second part which engages the upper surface of the flooring section, the two parts being removably connected together through a small opening in the flooring. As a result, individual flooring sections can be removed to provide access through the flooring in emergency or critical situations while at the same time allowing the remainder of the flooring to retain collected debris.
