NONCOMBUSTIBLE LIGHTWEIGHT VISCOELASTIC CEILING BOARD MEMBER CONSTITUTED IN VIBRATION ABSORPTION SUSPENDED CEILING
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. The ceiling board member having the lightweight flexibility is composed of a noncombustible lightweight viscoelastic ceiling board constituted of a single or a plurality of members and a ceiling board frame having a constitution fitted to the ceiling joist rail provided in a peripheral edge part of the noncombustible lightweight viscoelastic ceiling board.
【課題】地震時における天井への振動や変位を吸収し抑制して天井の崩壊落下を防止することのできる吸振つり天井に構成される不燃軽量粘弾性天井板部材を提供する。【解決手段】天井スラブに固定された吊りボルトに直接取り付けられた野縁レールと、該野縁レールに差し込み取り付けられる少なくとも軽量柔軟性を有する天井板部材とを有し、天井構成は中央部の固定範囲天井部分、及び、外周部の壁面と中央部の固定範囲天井部分との間に設けた吸振範囲天井部分から構成され、該軽量柔軟性を有する天井板部材は単一又は複数の部材により構成された不燃軽量粘弾性天井板と、該不燃軽量粘弾性天井板の周縁部に設けられた該野縁レールに嵌合する構成を有する天井板枠とからなる。【選択図】図１
