PIT COVER

CONSTITUTION: A pit cover 10 is a decorative cover made of a synthetic resin that can accommodate a decorative material 104 on an upper surface thereof, the pit cover including a reception frame 12, and an upper cover 14 and an inner cover 16 that are attachable to and detachable from the reception frame. The lower part of the reception frame is fitted to a raised pipe 102 of a pit 100. The upper cover has a recess 40 into which the decorative material is fitted, and is mounted on the upper part of the reception frame. The inner cover is held inside the reception frame by being locked by a protrusion 32 formed on an inner surface of the reception frame lower part.EFFECT: Since a pit cover is made of a synthetic resin and a reception frame is made to connect to a raised pipe of a pit, workability of the cover is improved.SELECTED DRAWING: Figure 1 【構成】 桝蓋１０は、上面に化粧材１０４を収容可能な合成樹脂製の化粧蓋であって、受枠１２と、受枠に対して着脱可能な上蓋１４および内蓋１６とを含む。受枠は、その下部が桝１００の立上り管１０２と嵌合される。上蓋は、化粧材が嵌め込まれる窪み部４０を有し、受枠の上部に装着される。内蓋は、受枠下部の内側面に形成される突出部３２に係止されることで、受枠の内部に保持される。【効果】 桝蓋を合成樹脂製とし、桝の立上り管に対して受枠を接続するようにしたので、蓋の施工性が向上される。【選択図】 図１
