Protective cover sections and sealed assemblies thereof fully enclose structural shapes such as I-beams and the like to protect them against bacterial growth, mildew, corrosion and the like. Each cover section is generally thin-walled, substantially rigid, flexible and tough so as to resist chipping, denting and peeling. Each cover section has flexural joint portions that facilitate adjustment thereof to cover a range of structural shape dimensions. On-site applied assemblies of the cover sections are adaptable to a variety of existing structures and include a pair of cooperating cover sections with opposed edge portions of one connected to edge portions of the other at a pair of opposed, sealed, continuous seams extending along the cover. A cooperating pair of cover sections overlaps a next adjacent cooperating pair of cover sections and these pairs are connected at a sealed, continuous, circumferential seam and the ends of the assembly of cooperating pairs are closed by sealed, continuous, circumferential end seams. The assemblies closely conform to the cross-sectional shape of the structural shape covered and are secured thereto for a relatively close fit. In an adjustable form for making these cover sections one base has a plurality of interchangeable flange-forming sections of different dimensions for forming a cover for a range of flange dimensions.
A flexible protective cover section for covering a structural shape and the like comprising a corrosion-resistant body that is preformed to a set shape substantially conforming to at least a portion of external surfaces of a structural shape arranged along intersecting planes, said body having an intermediate body portion and a pair of oppositely inner side body portions arranged at an angle with and connected to said intermediate body portion at a flexural joint body portion that flexes to change the angle between said intermediate body portion and said inner side body portions so that said body adjusts to cover a range of structural shape dimensions, the thickness of said body being between about 0.020 and 0.090 inches.
A flexible protective cover section for covering structural shapes and the like comprising:
In a protective cover assembly for covering structural shapes and the like, a protective covering generally conforming to the outer surface configuration of the structural shape, said protective covering including a pair of opposed, similarly shaped cover sections of selected lengths each preformed to a set shape substantially conforming to and covering in excess of one half of a structural shape to provide a pair of opposed overlapping portions at opposite edges, and a sealed, continuous seam joining said overlapping portions throughout the lengthwise extent thereof, each said cover section having an intermediate body portion and a pair of oppositely disposed inner side body portions arranged at an angle with and connected to said intermediate body portion at a flexural joint body portion that flexes to change the angle between said intermediate body portion and said inner side body portions so that the covering adjusts to cover a range of structural shape dimensions, the thickness of each of said covering sections being between about 0.020 and 0.090 inches.
In combination with a structural shape having a web portion and a pair of opposed flange portions, a protective covering over said structural shape fully sealed off from the atmosphere, said protective covering including a pair of opposed, similarly shaped cover sections each preformed to a set shape substantially conforming to and covering in excess of one half of a structural shape to provide a pair of opposed overlapping portions at opposite edges, a sealed continuous seam joining each of said overlapping portions throughout the lengthwise extent thereof, each said cover section having an intermediate body portion and a pair of oppositely disposed inner side portions arranged at an angle with and connected to said intermediate body portion at a flexural joint body portion that flexes under pressure to change the angle between said intermediate body portion and said inner side body portions so that the cover sections adjust to cover a range of structural shape dimensions, an inner of said cover sections being adhesively secured to an exterior surface of one of said flange portions and to an external surface of said web, an outer of said cover sections being adhesively secured to said inner cover section along a pair of opposed, sealed, continuous seams and to the opposite surface of said web, and connecting means between the ends of said covering and said beam forming a sealed continuous bead to close off the ends of said covering, the thickness of each of said covering sections being between about 0.020 and 0.090 inches.
An adjustable form system for making flexible protective covering sections having a thickness between about 0.020 and 0.090 inches for structural shapes comprising:
