  • Patent number: 5806266
    Abstract: A beam member for use in construction, particularly as a waler in concrete form assemblies, and a method of producing the same. The beam member is flexible to a preselected curvilinear shape and adapted to be held in said preselected curvilinear shape, and includes a flexible face and a plurality of flange members secured to and upstanding from the flexible face, the flange members being arranged side-to-side in two rows, one each of which rows is adjacent a corresponding one of opposing sides of the flexible face. Each of the flanges has a terminal end section extended parallel to the flexible face and is separated from an adjacent flange by a distance which increases from the attachment of the flange at the flexible face to said terminal end section whereby the beam member is laterally flexibly movable to conform to a preselected curvilinear shape. A strap is secured to the terminal end section of the flanges to maintain the preselected curvilinear shape of the beam member.
