Abstract: A method for making a unitized, ready-to-install, mobile home ceiling structure is disclosed. The method comprises the steps of arranging a plurality of rectangular panels on a tunnel jig. A roof frame structure is then positioned and fastened on the back face surfaces of the panels by means of fasteners and adhesive along the bottom chords of intermediate roof frame truss members. The method additionally includes the step of fastening roof frame perimeter side edge rails and outer truss members to the panel arrangement perimeter by means of fasteners driven upwardly through the front face surface of the panels to extend through the panels and penetrate the side edges rails and outer truss members. The method includes the step of transporting the mobile home ceiling structure from the tunnel jig in ready-to-install condition wherein the setup time of the adhesive material does not restrict moving the unit.

Abstract: A mobile home ceiling unit and a method for manufacturing said unit are disclosed. The mobile home ceiling unit comprises an arranged plurality of panels fastened to a roof frame. The roof frame has an outer truss member at opposite ends and a multiplicity of intermediate truss members therebetween. Intermediate truss members being rigidly affixed to the panels by means of back fasteners and adhesive material. The roof frame additionally provides perimeter side edge rails. The side edge rails and outer truss members are fastened to the panels by means of front face fasteners along the perimeter of the front face surface of the panel arrangement. The front face surface perimeter of the ceiling unit is adapted to supportively coact along support wall means. The ceiling unit provides a concealed back fastened ceiling structure having unitized construction. A method for making said unitized, ready-to-install, mobile home ceiling structure is also disclosed.
