出しないように高さ調整モルタルの高さを低くして路面
より僅かに低くなるようにする作業が行われている。For example, when removing snow on a road in a snowy area with a snowplow during snowfall, the snow removal edge of the snowplow hits the upper end of the iron lid receiving frame that is slightly protruding on the road surface due to reduced pavement surrounding the iron lid receiving frame. Accidental damage may occur. Therefore, the work of lowering the height of the height-adjusting mortar so that the upper end of the iron lid receiving frame does not protrude from the road surface when the time of snowfall approaches near the road surface is performed.

ととなる。Then, after the thaw, in order to eliminate the step between the road surface and the iron cover receiving frame, the same operation as described above is performed to replace the height adjusting mortar, and thereafter, the surrounding road surface is similarly paved as described above.
従って、その作業の手間と費用は膨大となり、降雪地
方の大きな問題となっている。Therefore, the labor and cost of the work are enormous, which is a major problem in snowfall areas.

を特徴とする。The present invention relates to a manhole iron lid receiving frame structure in which a building block is stacked on an upper floor slab, and the height is adjusted with a height adjusting mortar or the like, and the outer peripheral surface of the iron lid receiving frame is vertically extended. At the same time, a locking edge is formed at the lower part of the inner periphery, and the ironing lid receiving frame is fixed to the building block inside by this locking edge, and the upper periphery of the iron lid receiving frame is aligned with the pavement surface of the road surface. Road pavement is not applied on the receiving frame.

ことになる。According to the above configuration, the iron cover receiving frame can be fixed to the building block only by the bolts, and the iron cover receiving frame can be removed without breaking the road surface pavement.
以下に本発明の実施例を図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
なお、上記従来技術と同様の部位は同一符号を用いて
説明する。Note that the same parts as those in the above-described conventional technology are described using the same reference numerals.
図において１は上床版であり、その上に築造ブロック
２を重ね、その上に高さ調整ブロック９を重ねる。In the figure, reference numeral 1 denotes an upper floor slab, on which a building block 2 is stacked and a height adjustment block 9 is stacked thereon.
この高さ調整ブロック９は高さの異なるものが複数用
意してあるもので、例えば降雪時のときに設置する高さ
のもの、雪解け後の高さのもの等が予め用意されてい
る。A plurality of height adjustment blocks 9 having different heights are prepared. For example, height adjustment blocks that are installed at the time of snowfall, heights after the thaw, and the like are prepared in advance.
10はこの高さ調整ブロック９の上に載せる鉄蓋受け枠
であり、外周面はフランジ等の突出物がない平面状とし
てあり、内周下部に係止縁10aが形成してあり、そこに
係止穴が所定間隔にあけてある。Reference numeral 10 denotes an iron lid receiving frame to be placed on the height adjusting block 9, the outer peripheral surface of which is a flat surface having no protrusions such as a flange, and a locking edge 10a is formed at a lower inner peripheral portion. Lock holes are provided at predetermined intervals.
なお、上記外周面の垂直方向の平面状態は断面形状に
おいて図示の如く垂直の他に末広がりの傾斜、逆傾斜等
を含む概念である。The vertical plane state of the outer peripheral surface is a concept including a divergent inclination, a reverse inclination, and the like in addition to the perpendicular as shown in the cross-sectional shape.
また、この係止縁10aの構成は上記の構成に限るもの
ではなく、第２図に示す如く内側肉厚部に係止凹部10b
を形成し、そこに係止穴を形成したものでも同様であ
る。12は蓋体である。Further, the configuration of the locking edge 10a is not limited to the above configuration, and as shown in FIG.
The same applies to the case where a locking hole is formed therein. 12 is a lid.
