Claim 3

A method according to claim 1 wherein the steps of applying foam material and adhering the panels and trusses together are preceded by a step of installing utility service in the superposed trusses and panels.

Claim 4

A method according to claim 1 wherein the step of superposing the unitary roof and ceiling structure on the side walls comprises lifting the unitary structure from an assembly location and transporting the unitary structure to a remote building constrUction location.

Claim 5

A sub-assembly for use in a building structure and comprising: ceiling panel means disposed in a horizontal plane and having a lower surface for defining an interior finished ceiling for the building structure, truss means overlying said panel means for supporting said panel means and for defining a roof system structure, and foam means adhered to an upper surface of said ceiling panel means and to at least portions of said truss means, said foam means constituting the primary joining means for adhering said panel means and said truss means together into a unitary roof and ceiling structure and imparting thermal insulation characteristics to said unitary roof and ceiling structure said sub-assembly being prefabricated and adaptable for movement to and installation on the upper terminals of vertically disposed building supports as an integral unit.

Claim 6

A sub-assembly for use in a building structure and comprising: ceiling panel means disposed in a horizontal plane and having a lower surface for defining an interior finished ceiling for the building structure, truss means overlying said panel means for supporting said panel means and for defining a roof system structure, and foam means adhered to an upper surface of said ceiling panel means and to at least portions of said truss means, said foam means constituting the primary joining means for adhering said panel means and said truss means together into a unitary roof and ceiling structure and imparting thermal insulation characteristics to said unitary roof and ceiling structure said sub-assembly being prefabricated and adaptable for movement to and installation on the upper terminals of vertically disposed building supports as an integral unit.

Claim 7

A building structure according to claim 4 further comprising utility service means penetrating at least portions of said truss means for distributing service through said building structure and further wherein said foam means is adhered to said utility service means for securing the same in said unitary roof and ceiling structure.

Claim 8

A building structure according to claim 4 wherein said truss means comprise a plurality of fabricated trusses each having an elongate lower member engaging said upper surface of said ceiling panel means and encased by said foam means.

Claim 9

A building structure according to claim 4 wherein said ceiling panel means comprises a plurality of ceiling panels arranged in a predetermined horizontal planar array.
