Abstract: A special stud which permits drywall installation on walls and ceiling surfaces independent of the structural qualities of the synthetic plastic material used in building panels. A stud member is positioned between adjacent building panel members which are preformed to form conduits in both the wall and ceiling members. Male attaching members such as lag screws or nails are partially inserted into the stud members so that their heads remain in the conduits to permit fastening thereto of column or roof beam structural steel members as well as rebar members. Furring strip members may be attached to the inside of the studs so that drywall members may be attached to the furring strip members.
