に関する。[Detailed description of the invention] (Industrial application field) This invention relates to iron lids with receiving frames for electric power, water intake valves, gas valves, telephone wiring, etc. The receiving frame is buried underground and is used on roads. Regarding an iron lid with a receiving frame installed in.

（従来の技術）従来より、この種の受枠付鉄蓋は種々な形状の
ものがあるが、通常は鉄蓋本体と受枠とが円形状
のものである。この考案の対象となる受枠付鉄蓋
はその鉄蓋本体が円形状のものに限る。(Prior Art) Conventionally, this type of iron lid with a receiving frame has been available in various shapes, but usually the iron lid body and the receiving frame are circular. The iron lid with a receiving frame that is the subject of this invention is limited to those whose iron lid body is circular.

切に行なうことができないと云う問題点がある。(Problem that the invention attempts to solve) The conventional iron lid with a receiving frame has a circular iron lid body.
Since the outer periphery of the upper end of the receiving frame is circular, there is a problem in that when installing it on a road, etc., the asphalt cannot be stamped (compressed) properly using a rammer (compressor) or the like. In other words, such stamping (compression) must be performed along the ring around the upper edge of the receiving frame, but since the upper edge is circular, it is very difficult to do so, and it is impossible to do it properly. There is a problem.

問題点を解決することを目的として提案するもの
である。 Further, the receiving frame installed on the road or the like in this manner has the problem that it is easy to separate from the asphalt pavement surface and it is difficult to maintain the horizontal position with respect to the road surface.
Therefore, this invention is proposed for the purpose of solving the problems of this type of conventional iron lid with a receiving frame.

It is composed of a receiving frame 3.

尚、実施例に係る受枠３の上端外周囲２は八角
形状に形成されている。 Note that the outer periphery 2 of the upper end of the receiving frame 3 according to the embodiment is formed in an octagonal shape.

る。(Effect of the invention) The iron lid with a receiving frame according to the invention configured as described above has the upper outer periphery 2 of the receiving frame 3 protruding laterally in a polygonal shape of more than a square, so that it can be easily used on roads. When installing and constructing the asphalt, the asphalt can be easily and accurately stamped (compressed) using a rammer (compressor) or the like. Further, after installation on a road, etc., the receiving frame 3 is difficult to separate from the asphalt pavement surface, and the horizontal position with respect to the road surface is accurately maintained.
