Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a noncombustible lightweight viscoelastic ceiling board member constituted in a vibration absorption suspended ceiling, capable of preventing a collapse fall of the ceiling, by absorbing and restraining vibration and displacement to the ceiling in an earthquake.SOLUTION: A noncombustible lightweight viscoelastic ceiling board member comprises a ceiling joist rail directly installed on a suspension bolt fixed to a ceiling slab and a ceiling board member insertably installed in the ceiling joist rail and having at least lightweight flexibility. A ceiling constitution is constituted of a fixation range ceiling part of a central part and a vibration absorption range ceiling part provided between a wall surface of an outer peripheral part and the fixation range ceiling part of the central part.
