必要とし、工事に手間を要するという問題があった。(1)) When carrying out work to raise the height several years later, it is necessary to excavate to at least the top of the pedestal or the housing of the humid pipe, lift the iron cover holder, insert a washer, etc., and perform the work. There was a problem in that it required a lot of time and effort.
（目的）
本発明の目的は、このような従来構造の問題を解決でき
、高さ調整作業および嵩上げ工事を容易かつ短時間で行
いうるハツト型鉄蓋受枠を提供することである。(Objective) An object of the present invention is to provide a hat-shaped iron lid holder frame that can solve the problems of the conventional structure and allows height adjustment work and raising work to be performed easily and in a short time.
本発明は、ハツト型鉄蓋受枠を鉄蓋を支持する上部枠体

状態で組付けられている。The lower frame has a substantially cylindrical shape, and has several pinches (for example, 3 pins) of male threads 5 formed on its outer surface, and the upper frame 4 has a hat shape that covers the lower frame 2 from above. ,
Several pinches (for example, two
A female thread 6 of ~3 pitches is formed, and both frames 2
．． 4 is assembled in such a manner that the height H can be adjusted within a predetermined range (for example, by fine adjustment of about 5 to 40 degrees) by adjusting the depth of screw engagement.
下部枠体２の下部には３箇所に張出し部７が形成され、
これら張出し部を筺体１にボルトナツト′ｆ＠粘するこ
とにより固定されている。Overhanging portions 7 are formed at three locations at the bottom of the lower frame body 2,
These projecting portions are fixed to the housing 1 with bolts and nuts.

７を締結することにより、固定する。When installing the hat-shaped iron lid receiving frame described above, the lower frame body 2 that has been separated in advance is fastened to the upper surface of the housing 1 such as a concrete pedestal or humid pipe that has already been installed underground, and the overhanging part 7 is attached. By doing so, it is fixed.
この場合は筐体１の上方のみを掘った状態にしておけば
充分である。In this case, it is sufficient to leave only the upper part of the housing 1 in a dug state.

(Figure) can be easily adjusted in height.
然る後、周辺に土を埋め戻すとともに瞑圧し、必要な舗
装仕上げを行って工事を完了する。After that, the surrounding area will be backfilled with soil and compressed, and the necessary paving will be completed to complete the construction work.
なお、埋め戻しの途中において高さの再調整が必要な場
合は完全に填圧していなければ上部枠体４を回動させる
ことができるので、この再調整も容易に行うことができ
る。In addition, if it is necessary to readjust the height during backfilling, the upper frame 4 can be rotated as long as the pressure is not completely filled, so this readjustment can be easily performed.
設置後何年か経ち、沈下等のため嵩上げする場合は、上
部枠体４を回動させうるところまで周囲を掘削すれば、
ねじを利用して容易に嵩上げすることができ、然る後填
圧および必要な舗装仕上げを行って工事を完了する。If you need to raise the height several years after installation due to subsidence, etc., excavate the surrounding area to a point where the upper frame 4 can be rotated.
It can be easily raised using screws, and the construction is completed by applying appropriate post-filling pressure and completing the necessary paving.
以上説明した実施例によれば、ハツト型鉄蓋受枠を上部
枠体４と下部枠体２とに分割するとともにこれらをねじ
係合させて組付けるので、設置時の高さ調整および後日
の嵩上げ工事に際し、従来のようにワッシャー等のスペ
ーサを挿入する必要がなく、単にねじを＋同士だけの簡
単な作寥でこれらの工事を行うことができる。According to the embodiment described above, the hat-shaped iron lid receiving frame is divided into the upper frame body 4 and the lower frame body 2, and these are screwed together and assembled, so that the height can be adjusted at the time of installation, and the height can be increased later. During construction, there is no need to insert spacers such as washers as in the conventional case, and these constructions can be carried out by simply screwing screws together.
また、嵩上げ時の掘削量も少なくて済ますことができる
。Further, the amount of excavation required for raising the height can be reduced.
こうして、設置および嵩上げの工事手間を短縮でき、工
事費の節約を図ることができる。In this way, it is possible to shorten the construction work required for installation and raising the height, and to save construction costs.
さらに、分割構造にしたので、上部枠体４および下部枠
体２のいずれかに破損や摩耗が生じた場合、その部分の
みの取替えで済ますことができ、経済性を向上させるこ
ともできる。Furthermore, since the structure is divided, if either the upper frame 4 or the lower frame 2 is damaged or worn, only that part needs to be replaced, thereby improving economic efficiency.
以上の説明から明らかなごとく、本発明によれば、設置
時の高さ調節が容易でしかも後日の嵩上げ作業も容易に
行うことができ、これらの工事時間の短縮および工事費
用の節減を図りうるハフ）−型鉄蓋受枠が提供される。As is clear from the above description, according to the present invention, the height can be easily adjusted at the time of installation, and work to raise the height at a later date can be easily carried out, thereby shortening the construction time and reducing construction costs. Hough)-type iron lid holder frame is provided.
