Abstract
A temporary shield erected between two flanged structural members of a bridge or other structure, a kit therefor, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift up of the shield.
Claims14
A shield erected between two flanged structural members, the shield comprising a plurality of length-adjustable beams having end portions which rest on flanges respectively of the structural members, and the shield further comprising decking attached to said beams, wherein said decking has a plurality of oblong openings therein, the shield further comprising a plurality of rings slipped onto said beams for attaching said decking to said beams, each said ring having a threaded stud extending from a wall thereof and received in a respective one of said openings, an elongate washer covering said respective opening, and a nut applied to said stud to attach said decking to said respective beam.
A shield erected between two flanged structural members, the shield comprising a plurality of length-adjustable beams having end portions which rest on flanges respectively of the structural members, and the shield further comprising decking attached to said beams, wherein said decking has a plurality of oblong openings therein, the shield further comprising means for attaching, from underneath said decking and said beams, said beams to said decking, wherein said means for attaching comprises at least one clip, said clip including a pair of brackets having first elongate threaded portions respectively which extend downwardly through a respective one of said decking openings and alongside and below opposite sides respectively of a respective one of said beams and further having second elongate portions respectively which extend from and normal to upper ends of said first elongate portions respectively and which extend in directions away from said respective beam and alongside said decking and beyond ends respectively of said respective opening to lie on said decking, said clip further including an elongate plate having first and second end portions and disposed below said respective beam and extending between said brackets, said first end portion having an aperture therein, one of said first elongate portions received in said aperture, and a fastener threadedly engaging said one of said first elongate portions and urging said respective beam against said decking, and said second end portion having a pair of prongs defining a slot there between, an other of said first elongate portions received in said slot, and a fastener threadedly engaging said other of said first elongate portions and urging said respective beam against said decking.
A kit for erecting a shield, the kit comprising a plurality of beams which are length-adjustable to fit a distance between two flanged structural members so that end portions of each of said beams rest on flanges respectively of the structural members, decking, and fasteners for attaching said decking to said beams, wherein said decking is corrugated sheet and has a plurality of oblong openings therein, the kit further comprising a plurality of rings shaped to be slipped onto said beams for attaching said decking to said beams, each said ring having a threaded stud extending from a wall thereof and receivable in a respective one of said openings, and the kit further comprising elongate washers for covering the oblong openings respectively in said decking and nuts for application to said studs to attach said decking to said beams.
A method for erecting a shield comprising the steps of adjusting the lengths of a plurality of beams so that end portions of each of the beams rest on flanges of two spaced structural members respectively, placing the beams between the structural members so that the end portions of each of the beams rest on the flanges respectively, and attaching decking to the beams, wherein the step of attaching the decking comprises inserting, from underneath said decking and said beams, a pair of brackets in at least one oblong hole in the decking to bear on the decking and to extend downwardly therefrom along sides of a respective beam, and attaching, from underneath said decking and said beams, an elongate plate to the brackets so that it bears against the respective beam.
