るという問題もある。[Problems to be solved by the invention] In the conventional manhole cover device, the receiving frame partition body that is removably attached within the receiving frame is formed of a beam member with a square cross section, and the upper surface and the lid receiving step surface ( Shoulder part where the upright wall of the side wall of the receiving frame is erected)
are flush with each other and are configured to support the outer peripheral flange at the upper end of the lid body, so that the lid holder step surface inside the holder frame and the upper surface of the holder frame partition (beam member) extend in the length direction. Provided with multiple protruding ridges,
A concave-convex engaging portion that engages with this protruding ridge when closing the lid is provided on the lower side of the lid outer periphery flange, so that when the lid is closed, a concave-convex engaging portion is provided on the lower side of the lid outer periphery flange. Therefore, the structure becomes complicated, and the lid closing operation becomes troublesome because it requires positioning of the concave and convex engaging portions. Moreover, since the lid is water-tightly sealed with a sealant such as grease that is heated to the flange support, this sealant deteriorates and must be refilled with the sealant each time the lid is opened and closed. This method is troublesome, and has the disadvantage that reliable waterproofing and vibration-proofing properties of the lid cannot be ensured over a long period of time. Furthermore, since the receiver frame partition made of the beam member is not provided with a partition plate that partitions the adjacent portions of the flanges of each lid, a rectangular partition frame is defined for each lid around the fitting portion of each lid. There is also the problem that the lid cannot be formed and the design appearance in the closed state is impaired.

る。 A rectangular receiving frame A has an approximately inverted T-shaped cross section with an inward flange and an outward flange provided at the lower end of the side wall, and a receiving frame partition B that is removably attached to the receiving frame A is attached to the upper end surface of the side wall of the receiving frame. An inward flange 32, which is flush with the inward flange of the receiving frame, is provided on both sides of the lower end of the partition plate 31, which is flush with the inward flange of the receiving frame.
33, and the upper outer periphery flange 41 of the lid C is supported by the inner step surface of the receiving frame A, and the entire periphery of the bottom wall 45 of the lid is connected to the receiving frame A and the upper peripheral flange 41 of the lid C. Since the lid receiving structure is in close contact with the rubber gasket 37 attached to the inward flange of the receiving frame partition B, the lid supporting portion does not have a protruding ridge and a concave/convex engaging portion that limit the movement of the lid as in the conventional case. There is no need to provide one, which simplifies the structure, and also eliminates the need for alignment of the protruding ridge and the concavo-convex engaging portion during the lid-closing operation. Furthermore, reliable waterproof and vibration-proof properties of each lid body C can be ensured over a long period of time, eliminating the conventional problem of deterioration of the sealant and the trouble of refilling the sealant. be able to.
