This invention relates to work deck platform systems which are installed temporarily under or upon structures such as bridges to allow workers and equipment to repair and renovate said structure and more particularly to an improved fastener clip for securing deck panels upon support cables to allow for faster, easier and safer installation of the work deck platform and better debris containment.
Current temporary work platform deck floor panels are secured to wire rope support cables in several ways. One common means is through holes cut into the corrugated deck panels to allow U-shaped bolting hardware to be inserted through the hole to grab onto the cable and an oversized washer or plate covers the hole and is attached to the U-bolt with a nut to secure the deck panel to the support cable.
The fastening hardware of known current means consists of multiple parts which must be assembled by the worker and then held in place until securely tightened using hand tools. With the fastening hardware consisting of multiple parts the installation process is awkward, as the worker must assemble the hardware, then hold it in place while also grabbing the hand tools and tightening the hardware.
The installation process is time consuming and there is also opportunity for pieces of hardware to be dropped during installation allowing metal to fall to the ground, highway or water below creating a danger to motorists, persons and property below.
Also work deck platforms are normally installed at elevated heights where workers have a limited surface area to stand upon and work from and whereby the less equipment and movement required the easier and safer their job becomes.
Though care is taken to keep the holes covered, debris inevitably escapes the enclosed work area through these holes in the deck floor panels. Fastening hardware which completely covers the opening in the deck panel would be desirable.
It is the object of this invention to provide a pre-assembled deck panel to support cable, hinged fastener clip, which can be used to secure work deck platform floor panels upon wire rope support cables without having to assemble the fastener clip on location.
It is another object of this invention to provide a deck panel to support cable, hinged fastener clip, which better prevents dust and debris from escaping outside the containment area by completely covering the securing hole in the work deck platform floor panel through which the fastener clip is inserted.
In summary the deck panel to support cable, hinged fastener clip of this invention consists of two plates, attached together as a hinge, a pin holding the plates together to complete the hinge and a rod partially bent to shape approximately like a hook with the end of the hook threaded, and a hex nut. Though exact hardware dimensions may vary the general shape of the hooked rod remains approximately the same so that when the non-hooked part of the rod is attached to the underside of one of the hinge plates with the hooked end extending towards the corresponding hinge plate; the hook shaped portion of the rod is shaped to grasp partially around a cable with the threaded end of the hooked rod protruding up through a hole in the corresponding hinge plate. The hex nut is then threaded onto the protruding threaded end of the hooked rod to keep it in place. For example purposes, though dimensions need not be exact the hinge plates of this invention when attached together as a hinge are approximately 1.5 inches wide by 0.1250 inches thick by 9.0 inches long. One hinge plate is approximately 5.5 inches long with a 0.625 inch hole located 3.5 inches from the end opposite the hinge pin along the centerline. The hinge plate forming the other side of the hinge is approximately 3.5 inches long. The steel hooked rod is approximately 4 inches long by approximately 0.442 inches diameter with approximately a 0.625 inch length of one end threaded. The Hooked Rod is bent 60-degrees approximately 1.3125 inches from the tip of the threaded end and bent in opposite direction 30-degrees approximately 2.17 inches from the centerline of the threaded end after the first bend is made. The hinge pin is standard length and diameter so as to hold the two hinge plates together. The hex nut is standard size and threading needed to thread onto the threaded end of the hooked rod.
The two hinge plates are attached together with a hinge pin as you would a common hinge. The hinge is then placed with both plates laying flat on the same general plane and so that the hinge pin portion of the plates is facing up. The hooked rod is attached at the non-threaded end to the underside of the 3.5 inch hinge cover plate so that the threaded tip of the hooked rod protrudes up thru the 0.625 inch hole in the 5.5 inch hinge plate when the entire hinge plate assembly is placed flat with both sides of the hinge opposite one another and on the same general plane.
