UNDERFLOOR INSPECTION HOLE
To provide an underfloor inspection hole allowing on-site installation to be shorten.SOLUTION: An underfloor inspection hole 1 is arranged on an opening part 2 formed on a floor. The underfloor inspection hole 1 is provided with: an inner and outer integrated frame 30 formed by integrating an inner frame and an outer frame; a lid plate 50 plated on an inside of the inner and outer integrated frame 30; and a frame receiving member 7 receiving the inner and outer integrated frame 30 fixed on an inner peripheral surface of the opening part 2. The inner and outer integrated frame 30 comprises: an inner flange part 31 covering the lid plate 50 by protruding to an inner side of the opening part 2; and an outer flange part 32 protruding to an edge of the opening part 2. The frame receiving member 7 comprises: a hook part 61 hooked on the edge of the opening part 2; an upper stage part 63 and a lower stage part 66 supporting the inner and outer integrated frame 30; and a rising part 62 connecting the hook part 61 and the upper stage part 63. The rising part 62 has a vertical width h to make the inner and outer integrated frame 30 supported with the upper stage part 63 and a lower stage part 66 adequate height from the floor.SELECTED DRAWING: Figure 2
【課題】現場での施工を短縮し得る床下点検口を提供する。【解決手段】床に形成された開口部２に設けられる床下点検口１である。床下点検口１は、内枠および外枠を一体化した内外一体枠３０と、内外一体枠３０の内側に張られた蓋板５０と、開口部２の内周面に固定されて内外一体枠３０を受ける枠受材７とを備える。内外一体枠３０は、開口部２の内側に張り出して蓋板５０を覆う内鍔部３１と、開口部２の縁に張り出した外鍔部３２とを有する。枠受材７は、開口部２の縁に掛けられる掛部６１と、内外一体枠３０を支持する上段部６３および下段部６６と、掛部６１と上段部６３とを接続する立ち上がり部６２とを有する。立ち上がり部６２は、上段部６３および下段部６６に支持された内外一体枠３０を床に対して適切な高さにする上下幅ｈを有する。【選択図】図２
