Abstract
This invention relates to a novel structure for securely joining ceiling boards, wainscots and other similar types of paneling and boarding to supports or base members such as joists or furring strips. This joining structure finds application in securing ceiling boards (such as gypsum boards or slag wool boards) having relatively low mechanical strength to joists. Employment of the novel and unique joining devices permits easy construction and assembly at high working efficiency. Since the boards are joined together securely by the devices fitted into slots formed at the edges of the boards and are not suspended from the ceiling but are tightly attached to the joists, an elegant and monolithic finish as well as increased structural strength is provided.
Claims6
Means for forming a planar surface comprising a plurality of substantially parallel base members spaced apart and parallel to said surface, each of said members being provided with a joining device,
- each said joining device comprising a substantially flat upstanding plate portion adjacent one side of each of said base members and affixed thereto, an engaging plate substantially perpendicular to said upstanding plate and extending on either side of the edge of said upstanding plate remote from said base members,
- a plurality of substantially flat members adapted to form said surface and having slits corresponding to said engaging plate, said engaging plate in said slits, whereby said flat members are securely joined in an end-to-end relationship,
- each said joining device being provided with a rib flange perpendicular to said upstanding plate and extending outwardly from one side of said upstanding plate, said flange being parallel to said engaging plate and spaced therefrom by a distance substantially equal to the thickness of said flat members from said surface to said slits.
