CONSTITUTION: A light-frame assembly of ceiling consists of an insert member(100), a carring channel(200) and a coupling bracket. The insert member is installed in a slab(S) and a screw groove(110) is formed on the exposed part of the insert member. The carring channel is arranged on the lower part of the insert member, comprises a plurality of hooks(220) for supporting an M-bar and a sliding hole(210) is formed on the top of the carring channel. One side of the coupling bracket is screwed to the screw groove of the insert member and the other side is inserted into the inner side with the sliding hole while sliding along the sliding hole. |
