INSTALLING APPARATUS OF A CEILING PLASTER BOARD

摘要

A device for mounting plasterboards in a ceiling is provided to decrease noise transmitted from upstairs and to combine the plasterboard with the ceiling firmly by fitting a projection of the plasterboard to a groove of adjacent plasterboard. An anchor bolt(10) is inserted to a hole formed in a ceiling(1), and a screw rod(30) with a thread(31) is thread-connected to the lower part of the anchor bolt and inserted to a penetration hole(21) of a plasterboard(20) to support the plasterboard with a washer(98) and a bolt(99). Plaster(40) is spread between the lower part of the ceiling and the plasterboard to combine the screw rod with the anchor bolt firmly. A seating groove(22) is formed in the lower part of the plasterboard to restrict the bolt from being protruded from the plasterboard, and the screw rod and the bolt are shielded by spreading plaster.
