CEILING INSPECTION PORT AND CONSTRUCTION METHOD THEREOF

To provide a ceiling inspection port contributing to the improved design of the indoor side without exposing an inner frame, reassuring a space near an opening of the inspection port, contributing to the improved workability of maintenance and inspection of wiring and piping, saving a manufacturing process at a construction site, and contributing to the compliance of the entire construction plan.SOLUTION: A ceiling inspection port comprises a rail 1 formed at an opening wall W situated around an opening H of a ceiling material S and a closing member 2 sliding the rail 1. The rail 1 has a rail first end 11 situated at one end side in a parallel direction to the opening H and a rail second end 12 situated at the other end side in the parallel direction and at the opening H side in an orthogonal direction to the opening H rather than the rail first end 11. The closing member 2 has a plate-like part 21 in a substantially same shape and in a same dimension with the opening H and a rotational shaft part 22 mounted at one end side of the plate-like part 21 and stored in the rail 1. In a closed state, the plate-like part 21 is stored in the opening H in a flush shape and the rotational shaft part 22 is situated at the rail first end 11 and in an opened state, the rotational axis part 22 is situated at the rail second end 12.SELECTED DRAWING: Figure 1 【課題】内枠を露出させずに屋内側の意匠性の向上に寄与し、点検口の開口付近のスペースを確保して配線・配管等の保守・点検の作業性の向上に寄与し、施工現場での製作工程を省いて全体の施工計画の順守に寄与する天井点検口を提供すること。【解決手段】天井材Ｓの開口Ｈの周囲に位置する開口壁Ｗに形成されたレール１と、レール１をスライドする開閉部材２とを備え、レール１は、開口Ｈに対して平行方向の一端側に位置するレール第１端部１１と、レール第１端部１１より開口Ｈに対して平行方向の他端側かつ直交方向の開口Ｈ側に位置するレール第２端部１２とを有し、開閉部材２は、開口Ｈと略同形かつ同寸法の板状部２１と、板状部２１の一端側に取り付けられてレール１に収まる回転軸部２２とを有し、閉状態で、板状部２１が開口Ｈに面一状に収まり、回転軸部２２がレール第１端部１１に位置し、開状態で、回転軸部２２がレール第２端部１２に位置する。【選択図】図１
