Patent number: 5890327Abstract: A method of reinforcing or retrofitting building roof structures against hurricane-force winds which does not require removal of part or all of the roof. The improved method includes directing a thin stream of a liquid polymer foam adhesive under pressure upwardly along the intersections of the rafters or support members and the roof panels, preferably on both sides of the support members. The foam adhesive then creams and foams, forming polymer foam adhesive gussets which firmly adhere to the adjacent surfaces of the support members and roof panels. This method increases the pull-off strength of a roof about seven fold and is able to withstand hurricane-force winds.Type: GrantFiled: December 2, 1996Date of Patent: April 6, 1999Assignee: ITW FoamsealInventors: N. Keith Merser, Frederick A. Kish

Patent number: 5861119Abstract: The method of forming rigid panel assemblies of this invention eliminates the requirement for mechanical fasteners and may be used to bond wall boards to studs, floor joists to wood flooring such as plywood or OSB boards and trusses to ceiling panels. The method of this invention includes applying a thin bead of a thoroughly mixed two-component liquid polyurethane foamable resin adhesive on the surface where the components are to be joined. The foamable resin is formulated to provide a long tack time or delay curing until the assembly is complete. The foamable resin is then allowed to cream and rise before bonding. Where the bead is applied to the side faces of the support members, the support members are preferably turned to orient the foam beads over the fibrous panel, which is preferably supported on a flat horizontal support surface.Type: GrantFiled: April 18, 1997Date of Patent: January 19, 1999Assignee: Illinois Tool Works, Inc.Inventor: N.

Patent number: 5810956Abstract: A method of filling a seam of a structural panel assembly utilizes a non-foaming, thixotropic, two-component polyurethane elastomeric material. The thixotropic, elastomeric material is prepared by rapidly mixing and initiating the reaction of a first thixotropic component comprising an isocyanate-terminated compound having at least two reactive isocyanate groups and a second thixotropic component comprising a hydroxyl-terminated compound having at least two reactive hydroxyl groups. Each of the first and second thixotropic components include from about 3% to 8% by weight fumed silica. The second thixotropic component also includes from about 10% to about 50% filler. The thixotropic elastomeric material is applied over the seam of a panel assembly. The method then includes fluidizing the thixotropic elastomeric material and driving the thixotropic elastomeric material into the seam of the panel assembly.Type: GrantFiled: July 1, 1996Date of Patent: September 22, 1998Assignee: ITW Foamseal, Inc.Inventors: Rick A.

Patent number: 5683526Abstract: A clamp holds a wall panel against an adhesive bead on a wall frame support assembly as the adhesive bead cures. The clamp is actuated to secure the clamp to the support assembly adjacent the panel and hold the panel against the adhesive bead as the bead cures. In a preferred embodiment, the clamp includes a clamping portion having vacuum chambers and a reference surface. A vacuum is drawn on the vacuum chamber, thereby pulling the edges of abutting panels against the reference surface, drawing adjacent panel edge portions of the panels in the parallel relation. The clamping portion also includes a mechanical control which secure the clamping portion to the support assembly holding the panels against the adhesive in coplanar relation. In a method according to this invention polymer adhesive is applied to coplanar surfaces of support members. A clamp is placed adjacent a panel and actuated to hold the panel against the first surface of the clamp.Type: GrantFiled: August 22, 1995Date of Patent: November 4, 1997Assignee: Foamseal, Inc.Inventors: Bruce T. Guilmette, N. Keith Merser, Glen P. Lloyed

Patent number: 5552095Abstract: The method of forming rigid panel assemblies of this invention eliminates the requirement for mechanical fasteners and may be used to bond wall boards to studs, floor joists to wood flooring such as gypboards, fiberboards, plywood or OSB boards and trusses to ceiling panels. A preferred method of this invention includes applying a thin bead of a thoroughly mixed two-component liquid polyurethane foamable resin adhesive on the surface where the components are to be joined. The foamable resin is formulated to provide a long tack time or delay curing until the assembly is complete. Where the bead is applied to the side faces of the support members, the support members may be turned to orient the foam beads opposite the fibrous panel, which is preferably supported on a flat support surface, most preferably a vacuum plate which draws the panel flat.Type: GrantFiled: July 9, 1993Date of Patent: September 3, 1996Assignee: Foamseal, Inc.Inventors: N. Keith Merser, Stanley E. Wencley
