CEILING SOUNDNESS EVALUATION MECHANISM AND CEILING STRUCTURE
To provide a ceiling soundness evaluation mechanism and a ceiling structure which have a simple structure that does not require a power source and can reliably evaluate the soundness of the ceiling of a building on which an earthquake force has been applied while reducing the cost of construction.SOLUTION: The ceiling soundness evaluation mechanism includes: a light emitting unit 10, which is fixed to a wall P or a ceiling Q and emits light or is discolored by reacting a light-emitting material when the light emitting unit receives an external force; and a trigger unit 30, which moves in association with a relative displacement that has occurred between the wall and the ceiling and applies an external force so that the light emitting unit emits light or is discolored when the displacement is at least a predetermined distance.SELECTED DRAWING: Figure 1
【課題】電源を必要とせずに装置構成を簡略化し、施工コストを低減しつつも地震力が加わった後の建物の天井の健全性を確実に評価することができる天井健全性評価機構及び天井構造を提供すること。【解決手段】本発明には、壁Ｐ又は天井Ｑに固定され、外力を受けた際に発光物質を化学反応させて発光又は着色する発光部１０と、壁と天井との間に相対的な変位が生じた場合に変位に連動して移動すると共に、変位が所定距離以上である場合に発光部に外力を与えて発光又は着色させるトリガ部３０と、を備えることを特徴とする、天井健全性評価機構である。【選択図】図１
