Lift ceiling and auditorium suspended ceiling
The invention relates to a lift ceiling which is arranged on a lifting steel frame. The lift ceiling comprises a first sealing frame, a second sealing frame, a plurality of cement boards, a plurality of collision preventing strips and a light emitting element, wherein the first sealing frame is fixedly arranged on the lifting steel frame, a steel bar is arranged on the first sealing frame; the first sealing frame is divided into two frames by the steel bar, namely a first frame and a second frame; the second sealing frame and the first sealing frame are fixedly connected; the second sealing frame is connected with the steel bar so as to enable the second sealing frame to be connected with the first frame; the cement boards are respectively arranged at the circumferential sides of the first and second sealing frames; the collision preventing strips are respectively arranged on the cement boards, and the light emitting element is arranged on the first sealing frame. According to the lift ceiling provided by the invention, through arranging the first sealing frame and the second sealing frame, the condition that the lift ceiling is of a closed space is guaranteed, so that the occurrence of a phenomenon of sound leakage is prevented, and then, the generation of a coupling effect is avoided. In addition, the invention further provides an auditorium suspended ceiling with the lift ceiling.
