ングを介在させるという方法も採用されている。[Detailed Description of the Invention] C. Prior Art] The receiving frame of a manhole cover is always in contact with the cover and is subjected to vibration every time a vehicle passes by, so the upper surface which is the contact surface with the counterweight is may be worn out or cracked. Noise is generated even when both the lid and holder are new.
If damage such as abrasion or cracking occurs between the manhole cover and the receiving frame, where there is even a risk that the cover may pop out, the noise and the risk of the cover popping out will further increase. Therefore, if both the manhole cover and the receiving frame are damaged to some extent, they can be replaced with new ones.Also, as a noise prevention measure, a rubber backing is interposed between the cover and the receiving frame. has also been adopted.

る。The conventional method described above, in which both the damaged lid and receiving frame are replaced with new ones, does not pose much of a problem with the lid, but the receiving frame is buried in the ground and surrounded by concrete. This requires a lot of time and effort to dig up the trench, bury a new one, pour concrete, and let it dry and cure. Depending on the installation location, this can cause significant traffic disturbances.

れがズレるという問題がある。On the other hand, if the lid is small and lightweight, the first interposition can be placed in the correct position, but
In the case of large heavy lids, the large heavy lid is generally set in the receiving frame by pulling it, which has the disadvantage that the backing may shift from its normal position, causing even more wobbling in some cases. Regardless of whether the backing is large or small, this backing is not fixed to either the lid or the receiving frame, but is simply interposed between the two, so there is a problem that it may shift over time.

部に嵌入したりする事もある。The above object of the present invention can be achieved by adopting the following means. In other words, the gist is that a circular or rectangular steel strip is placed at least in the center of the lower surface of a hard rubber strip that is formed in a circular or rectangular shape along the lid abutting surface of the receiving frame body. A receiving frame for a manhole cover, characterized in that the two are attached so as to be integrated, and the manhole cover is attached on the sealing contact surface using a fastening screw member, or an adhesive and the above-mentioned fastening screw member, and in this case, In order to stabilize the installation of the hard rubber band, a central protrusion is formed at the center of the lower surface of the hard rubber band, and the central protrusion is drilled into the seal contacting surface of the receiving frame body. It may fit into the mooring groove,
In addition, in order to improve the sealing performance, the inner edge of the hard rubber band is extended downward to form an inner edge protrusion, and a brim-shaped body is provided around it, and is perforated along the inner edge of the above-mentioned seal abutting surface. It may also fit into the provided seal groove.
なお本発明で用いる硬質ゴムは、各種ゴムにつき実験を
した結果、クロロブレンゴムが最適であるという事が判
った。As a result of experiments with various rubbers, it was found that chloroprene rubber is the most suitable hard rubber for use in the present invention.

望ましい。In addition, as a means of attaching the hard rubber band to the seal abutting surface of the receiving frame body, a fastening screw member alone is strong and detachable, but in the current situation where watertightness is required, fastening screws are used. It is most desirable to attach using a combination of a member and an adhesive.

接触れるのは硬質とはいえ柔軟なゴム帯体であるので振
動を吸収するものである。That is, in any case, the steel strip attached to the lower surface of the hard rubber strip firmly contacts the seal contact surface of the receiving frame and is screwed, so the connection between the two is strong and the steel strip is not buried. Since the lid contacting surface of the receiving frame is sealed by the hard rubber band, it will not be damaged by mackerel etc., and since the lid comes into direct contact with the hard but flexible rubber band. It absorbs vibrations.
