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.
