To provide a ceiling inspection port which facilitates mounting of a lid backing material on an inner frame, and which can fix firmly without positional deviation, loosening and the like.SOLUTION: An inner frame 20 is provided openably/closably in an outer frame 10 mounted on a ceiling, by framing tabular inner frame materials 21 in a square shape. A substantially L-shaped pressing member 30 is provided on an inside surface of the inner frame material. The pressing member includes: a vertical part 31 added on the inside surface of the inner frame material; and a horizontal part 32 on which a lower surface of a lid backing material 3 inserted in the inner frame and which also holds an upper surface of a lid finishing material 4. At the vertical part, cut-and-raised pieces 33a, 33b which can be folded to the inside of the inner frame are provided. By folding the cut-and-raised pieces in a state where the lid backing material is placed on the horizontal part, the cut-and-raised pieces and the horizontal part can hold the lid backing material. In a ceiling inspection port, positioning pieces 34a, 34b coming into contact with a side edge of the lid backing material according to the folding of the cut-and-raised pieces are provided, at a base end side lower part of the cut-and-raised pieces.SELECTED DRAWING: Figure 2
【課題】内枠への蓋下地材の取り付けを容易にすると共に、位置ずれやガタツキ等がなく強固に固定できる天井点検口を提供すること。【解決手段】天井に取り付けられる外枠１０内に開閉可能に設けられる内枠２０を、板状の内枠材２１を方形状に枠組みしてなり、内枠材の内側面に略Ｌ字状の押え部材３０を設け、押え部材は、内枠材の内側面に添設される垂直部３１と、内枠内に挿入される蓋下地材３の下面の載置と蓋仕上材４の上面の保持を兼用する水平部３２とを有し、垂直部に、内枠の内方に折り曲げ可能な切起し片３３ａ，３３ｂが設けられ、水平部に蓋下地材が載置された状態で、切起し片を折り曲げることによって、該切起し片と水平部とで蓋下地材を挟持可能にする天井点検口において、切起し片の基端側下部に、該切起し片の折り曲げに伴って蓋下地材の側縁に当接可能な位置決め片３４ａ，３４ｂを設ける。【選択図】図２
