CEILING STRUCTURE

To provide a ceiling structure which can be easily and quickly dealt with on-site even when the height of the high ceiling portion and the low ceiling portion that make up the ceiling of the building is changed and which can prevent an increase in work load even when an indirect lighting component is divided.SOLUTION: The ceiling structure is configured so as to be divided into a pre-mounted member 11 mounted to a high ceiling portion 31 and having a hanging connecting surface portion 11b descending toward a low ceiling portion 32, and a post-mounted member 12 fixed to the pre-mounted member 11, the post-mounted member having an upright connection surface portion 12a rising toward a lamp installation surface portion 12b on which a lamp 13 is installed and a high ceiling portion 31, extending until the upper end thereof is higher than the lower end of the hanging connecting surface portion 11b of the pre-mounted member 11, and overlapping the hanging connecting surface portion 11b of the pre-mounted member 11. The hanging connecting surface portion 11b of the pre-mounted member 11 is provided with a temporarily attached portion 11c, while the upright connection surface portion 12a is provided with a temporarily attached portion 12a1 that can be temporarily attached to a temporarily attached portion 11c of the pre-mounted member 11.SELECTED DRAWING: Figure 1 【課題】建物の天井を構成する高天井部と低天井部との高さが変更された場合でも現場で容易かつ迅速に対応すると共に、間接照明構成部材を分割して構成した場合でも作業の負担が大きくなることを防止できる天井構造を提供する。【解決手段】高天井部３１に取付けられ、低天井部３２に向かって下がる垂下り連結面部１１ｂを有する先付け部材１１と、灯具１３が設置される灯具設置面部１２ｂおよび高天井部３１に向かって上昇し、その上端部が先付け部材１１の垂下り連結面部１１ｂの下端部よりも高くなるまで延び、先付け部材１１の垂下り連結面部１１ｂに重なる起立連結面部１２ａを有し、先付け部材１１に固定される後付け部材１２とに分割して構成し、先付け部材１１の垂下り連結面部１１ｂには、被仮掛け部１１ｃを設ける一方、起立連結面部１２ａには、先付け部材１１の被仮掛け部１１ｃに仮掛け可能な仮掛け部１２ａ１を設ける。【選択図】図１
