To provide an attachment structure of a ceiling embedded device which can meet predetermined fire-resistance standards without lowering a ceiling significantly and facilitate construction of a heat insulation cover.SOLUTION: An attachment structure 2 of a ceiling embedded device includes: a ceiling 22 formed by a ceiling board 21 which meets predetermined fire-resistance standards; a ceiling embedded device 1 which is embedded on a ceiling space with a lower surface exposed at an opening provided at the ceiling 22; and a heat insulation box 5 which has a box shape in which the lower side is open and encloses the ceiling embedded device 1 with an upper plate 50 and a side plate 51. The heat insulation box 5 meets the same predetermined fire-resistance standards as the ceiling board 21.SELECTED DRAWING: Figure 1 【課題】 天井を大きく下げることなく所定の耐火基準を充たすことができ、断熱被覆の施工を容易にすることができる天井埋め込み装置の取付構造を提供する。【解決手段】天井埋め込み装置の取付構造２は、所定の耐火基準を充たす天井板２１により形成される天井２２と、前記天井２２に設けられた開口に下面を露出させつつ天井裏に埋め込まれる天井埋め込み装置１と、下方が解放された箱形状であり、上板５０と側板５１とで前記天井埋め込み装置１を囲う断熱ボックス５と、を備え、前記断熱ボックス５は前記天井板２１と同じ前記所定の耐火基準を充たす。【選択図】図１
