(57) [Abstract] [Objective] The present invention relates to a caulking agent for preventing crevice corrosion, a caulking agent for protecting a bolt, or an improvement of a method for removing and installing a nut in a caulking agent used for retaining a nut. It is a thing. [Structure] Replace the conventional nut with a conical nut whose portion covered with caulking agent is conical.
Description
【０００１】[0001]
この考案は、隙間腐食防止用のコーキング剤で被覆されたナットの取外し 及び取付け方法の改善に関するものである。 The present invention relates to an improved method of removing and installing a nut coated with a caulking agent for preventing crevice corrosion.
【０００２】[0002]
海水中の鋼構造設備には、電気腐食防止のために犠牲陽極が取付けられ、 その取付ネジ部の隙間腐食防止のためコーキング剤が使用されている。犠牲 陽極の消耗に伴う取替作業の際、硬化したコーキング剤を完全に除去しなけ れば、取付ナットを外すことが出来ず、作業性が悪い。 A sacrificial anode is attached to steel structure equipment in seawater to prevent electrical corrosion, and a caulking agent is used to prevent crevice corrosion of the mounting screw. If the hardened caulking agent is not completely removed during the replacement work due to the consumption of the sacrificial anode, the mounting nut cannot be removed, resulting in poor workability.
【０００３】[0003]
本案は、その欠点を除いて、従来の硬化するコーキング剤を用いても簡単 にナットの取外しができる袋ナットを開発しようとするものである。 This proposal aims to develop a cap nut that can easily remove the nut even with the use of a conventional hardening caulking agent, excluding its drawbacks.
【０００４】[0004]
いまその解決手段を図３を追いながら説明する。 コーキング剤で覆われている部分の形状が円錐状をした袋ナットを従来のナ ットに替えて取付ける。 Now, the solution means will be described with reference to FIG. Replace the conventional nut with a cap nut that has a conical shape in the part covered with caulking agent.
【０００５】[0005]
本案は図１、図２のような構造であるから、図３に示すようにこれを使用 するときは、ボルトを袋ナット１で固定し、コーキング剤６を充填し、取替 の際には袋ナット１を緩めれば、全てのコーキング剤６を壊さなくても簡単 に袋ナット１の取外しができる。また、下部が円錐状のため、スパナーで少 し緩めればコーキング剤６と接触面が離れ、手で緩められる。 Since the present proposal has a structure as shown in FIGS. 1 and 2, when using this as shown in FIG. 3, the bolt is fixed with the cap nut 1, the caulking agent 6 is filled, and the replacement is performed. By loosening the cap nut 1, the cap nut 1 can be easily removed without destroying all the caulking agent 6. Also, since the lower part is conical, if it is loosened a little with a spanner, the caulking agent 6 and the contact surface separate, and it can be loosened by hand.

したがって、著しい作業効率の向上ができるものである。又、閉所等酸欠 の危険のある場所での作業時間の短縮にも寄与できる。 Therefore, the working efficiency can be remarkably improved. It can also contribute to shortening the work time in places where there is a danger of oxygen deficiency such as in closed places.
