Description
本発明は、安定器取り付けのために道路照明鋼管柱に形成された開口部の腐食を補修して保護する道路照明鋼管柱の開口部の補修方法に関する。 The present invention relates to a method for repairing an opening of a road lighting steel pipe column that repairs and protects corrosion of the opening formed in the road lighting steel pipe column for ballast mounting.
道路照明鋼管柱内の下部には、安定器、開閉スイッチ等が設置されており、図１及び図２に示すように、それらを取り換えるために鋼管柱ａに開口部ｂが設けられる。そして、鋼管柱ａには、開口部ｂを囲むように、正面に開口を有する保護用の箱ｃが設置され、箱ｃの上面に水切り鉄板ｅが取り付けられている。また、箱ｃの正面には蓋ｄがビス止めされている。
しかし、経年劣化で、蓋ｄ及び蓋ｄを取り付けるビスが錆びついているものが多く見受けられる。さらに腐食が進むとビス止め孔も腐食してしまい、ビスが止められなくなったり、開口部ｂの周囲が欠け落ちたりする。現状では、新しい蓋とビスに交換することもできないこのような状態の道路照明鋼管柱が多数ある。
A ballast, an open / close switch, and the like are installed in the lower part of the road lighting steel pipe column. As shown in FIGS. 1 and 2, an opening b is provided in the steel pipe column a to replace them. And in the steel pipe pillar a, the protection box c which has an opening in the front is installed so that the opening part b may be enclosed, and the draining iron plate e is attached to the upper surface of the box c. A lid d is screwed to the front of the box c.
However, there are many cases in which the lid d and the screws for attaching the lid d are rusted due to aging. If the corrosion further progresses, the screw fixing hole also corrodes, and the screw cannot be stopped or the periphery of the opening b is chipped off. At present, there are many road lighting steel pipe columns in such a state that cannot be replaced with new lids and screws.
腐食した開口部をそのまま放置すると雨水が内部に侵入し、内部の電気部品が漏電して照明が点かなくなる虞がある。腐食がもっと進行すると、鋼管柱の強度が弱くなると共に、道路の美観にも悪影響があり、鋼管柱全体を取り換えるしかなくなる。鋼管柱全体を取り換えるには、費用が掛かり、資源の浪費にもつながる。
また、従来、照明器具本体の下方に延びる点検用スイッチや安定器を箱体に収納し、この箱体をベルトによって電柱の外周に取り付ける技術が知られている（特許文献１及び特許文献２参照）。
If the corroded opening is left as it is, there is a risk that rainwater will enter the interior and the internal electrical components will leak and the lighting will not turn on. If corrosion further progresses, the strength of the steel pipe column will be weakened and the aesthetics of the road will be adversely affected, and the entire steel pipe column will have to be replaced. Replacing the entire steel pipe column is expensive and wastes resources.
Further, conventionally, a technique is known in which an inspection switch or a ballast extending below the luminaire main body is housed in a box, and the box is attached to the outer periphery of a utility pole by a belt (see
本発明が解決しようとする課題は、既存の道路照明鋼管柱の安定器取付用開口部における腐食している箱体取付用ビス止め孔を利用することなく、開口部の両側に新たにビス孔を開けるだけで新しい箱体を取り付ける道路照明鋼管柱の開口部の補修方法を提供することにある。 The problem to be solved by the present invention is that a new screw hole is provided on both sides of the opening without using the corroded box mounting screw fixing hole in the ballast mounting opening of the existing road lighting steel pipe column. An object of the present invention is to provide a method for repairing an opening of a road lighting steel pipe column to which a new box is attached by simply opening the box .
本発明は、開口部が設けられ、正面に開口を有すると共に、上面に水切り鉄板が取り付けられた箱が前記開口部を囲むように設置され、前記箱の正面に蓋がビス止めされている道路照明鋼管柱を、上面及び後面が開口し、上面周囲に水切りツバが設けられ、前面に箱体開口部が形成され、下面に前記鋼管柱の外周面に嵌合する切欠き部が形成され、左右側面に箱体止めビス孔が形成されている箱体と、該箱体の前面を覆う新たな蓋とを用いて補修する道路照明鋼管柱の開口部の補修方法に関し、既存の蓋を取外してから、前記開口部の左右両側に取付け用ビス孔を前記箱体の箱体止めビス孔に合わせてあけ、次いで、前記箱体を前記開口部に合わせてはめこむと共に、前記箱体の水切りツバを既存の水切り鉄板と突き合わせ、前記箱体の箱体止めビス孔及び前記取付け用ビス孔へ通した箱体止めビスで前記箱体を取り付け、最後に前記新たな蓋を前記箱体の前面に被せ、蓋止めビスで新たな蓋を前記箱体に取り付ける。 The present invention is a road that has an opening, has an opening in the front, and a box with a draining iron plate attached to the upper surface is installed so as to surround the opening, and a lid is screwed to the front of the box The lighting steel pipe column has an upper surface and a rear surface that are open, a draining collar is provided around the upper surface, a box opening is formed on the front surface, and a notch that is fitted to the outer peripheral surface of the steel tube column is formed on the lower surface. The present invention relates to a method for repairing an opening of a road lighting steel pipe column that is repaired by using a box having a box body fixing screw hole formed on the left and right sides and a new cover that covers the front of the box. After that, mounting screw holes are formed on both the left and right sides of the opening to match the box fixing screw holes of the box, and then the box is fitted to the opening and the box is drained. Match the brim with the existing draining iron plate, the box of the box Attach the box with the box screw that has passed through the female screw hole and the mounting screw hole, and finally cover the front of the box with the new lid, and attach the new lid to the box with the lid fixing screw. Install .
本発明によれば、腐食した既存の蓋が取替不能な鋼管柱の開口部を、腐食している既存のビス止め孔を利用せずに、溶接作業を行なうことなく簡単な現場作業で補修することができ、開口部からの雨漏りを解消し、漏電等による照明灯の不具合も解決できる。
また、箱体が開口部周囲の腐食部分全体をカバーするので、腐食の進行を食い止めて、鋼管柱の強度を保つことができ、美観も向上する。
この結果、開口部だけの補修で鋼管柱を長期に使用できるようになり、鋼管柱全体の交換に比べて、コスト、資源消費量、及びＣＯ2排出量を削減することが可能となる。
According to the present invention, an opening of a steel pipe column in which a corroded existing lid cannot be replaced is repaired by a simple on-site work without performing a welding operation without using a corroded existing screw fixing hole. It is possible to eliminate rain leakage from the opening, and it is possible to solve the problem of the illumination lamp due to electric leakage or the like.
Further, since the box covers the entire corroded portion around the opening, the progress of the corrosion can be stopped, the strength of the steel pipe column can be maintained, and the aesthetic appearance is also improved.
As a result, it becomes possible to use the steel pipe column for a long time by repairing only the opening, and it is possible to reduce costs, resource consumption, and CO 2 emissions compared to the replacement of the entire steel pipe column.
図５に示すように、本発明で用いる道路照明鋼管柱用開口部保護箱は、既存の鋼管柱ａの開口部ｂを覆う寸法の箱体２と、箱体２の前面を覆う蓋１とを備える。箱体２及び蓋１は、鋼管柱ａと同様の鋼材を素材とする。
箱体２は、上面及び後面が開口しており、ほかの４面（前面、左右側面及び下面）を溶接して形成される。
図４に示すように、箱体２の上面周囲には、幅１０ｍｍ程度の水切りツバ５が溶接されている。箱体２の前面には、内部操作ができるように大きめの箱体開口部６が形成され、前面の上下部には、直径６ｍｍの蓋止め用ビス孔７がそれぞれ形成される。
また、箱体２の下面には、鋼管柱ａの外周面に嵌合するための切欠き部８が鋼管柱ａのサイズに合わせて形成される。
箱体２の左右側面には、鋼管柱ａに取り付けるための直径６ｍｍの箱体止めビス孔９が３個ずつ形成されている。
