本発明に係る防錆装置を実施するための形態を実施例に基づいて以下に説明する。   EMBODIMENT OF THE INVENTION The form for implementing the antirust apparatus which concerns on this invention is demonstrated below based on an Example.

実施例１に係る防錆装置につき、図１から図４を参照して説明する。図１の符号１は、本発明の防錆装置が適用される既設流体管である。この既設流体管１は、例えば、内部に流体としての上水が流れている水道管であり、この既設流体管１に新たな弁体等を設けるために、所定箇所を図示しない半径Ｌ１の長さを有するホールソー等の切削工具によって切断されている。   A rust preventive apparatus according to Example 1 will be described with reference to FIGS. Reference numeral 1 in FIG. 1 is an existing fluid pipe to which the rust preventive device of the present invention is applied. The existing fluid pipe 1 is, for example, a water pipe in which clean water as a fluid flows inside, and in order to provide a new valve body or the like in the existing fluid pipe 1, a predetermined portion is not shown in the length of a radius L1. It is cut by a cutting tool such as a hole saw having a thickness.

具体的には、図１及び図２に示すように、先ず既設流体管１には、既設流体管１を水密に密封するための筐体２が取り付けられる。この筐体２の上部には、水平方向にスライド移動することで筐体２内を開閉自在とする弁体３ａを備えた仕切部３が水密に取り付けられている。   Specifically, as shown in FIGS. 1 and 2, first, a housing 2 for watertightly sealing the existing fluid pipe 1 is attached to the existing fluid pipe 1. A partition portion 3 having a valve body 3a that can be opened and closed by sliding in the horizontal direction is attached to the upper portion of the housing 2 in a watertight manner.

この仕切部３の上端部に図示しないホールソーを備えた作業ケースを水密に取り付け、弁体３ａを開放した状態でホールソーを下方に向けて移動させることで、既設流体管１を不断流状態で切断する。したがって、既設流体管１の切断面１ａは、ホールソーによって切断されたことで平面視円弧状に形成されている。   A work case equipped with a hole saw (not shown) is attached to the upper end of the partition part 3 in a watertight manner, and the hole saw is moved downward with the valve body 3a opened, thereby cutting the existing fluid pipe 1 in an uninterrupted flow state. To do. Therefore, the cut surface 1a of the existing fluid pipe 1 is formed in an arc shape in plan view by being cut by the hole saw.

既設流体管１を切断した後は、ホールソーと既設流体管１の切断部とを作業ケース内に収納した後に弁体３ａを閉塞し、作業ケースを仕切部３から取り外すことで既設流体管１の切断作業を終了する。このとき、既設流体管１は図１に示すように、切断された状態で筐体２と仕切部３とで水密に密封されている。   After the existing fluid pipe 1 is cut, the valve body 3a is closed after the hole saw and the cut portion of the existing fluid pipe 1 are housed in the work case, and the work case is removed from the partition part 3 to remove the existing fluid pipe 1 End the cutting operation. At this time, as shown in FIG. 1, the existing fluid pipe 1 is sealed in a watertight manner by the housing 2 and the partition portion 3 in a cut state.

本発明の防錆装置は、前述のようにして筐体２内で切断された既設流体管１の切断面１ａを防錆するための装置である。   The rust preventive device of the present invention is a device for rusting the cut surface 1a of the existing fluid pipe 1 cut in the casing 2 as described above.

図２に示すように、仕切部３の上端部には作業ケース４が水密に取り付けられている。この作業ケース４内には、既設流体管１の切断面１ａを防錆するための、本発明における塗布手段としての回転体５が配置されている。また、作業ケース４の中央上部には、上下方向を向く貫通孔４ａ形成されている。   As shown in FIG. 2, a work case 4 is attached to the upper end portion of the partition portion 3 in a watertight manner. In this work case 4, a rotating body 5 is disposed as an application means in the present invention for rusting the cut surface 1 a of the existing fluid pipe 1. Further, a through hole 4a is formed in the upper center portion of the work case 4 so as to face in the vertical direction.

更に、作業ケース４の上端部には、回転体５を操作するための操作部６が設けられている。この操作部６は、貫通孔４ａを介して作業ケース４内に下端部側が挿通配置された操作棒８を備えており、この操作棒８下端部には、回転体５が取り付けられている。尚、操作棒８は、下端部が回転体５に接続されることにより、回転体５の上下方向を向く中心軸と同一軸線状に配置されている。   Furthermore, an operation unit 6 for operating the rotating body 5 is provided at the upper end of the work case 4. The operation portion 6 includes an operation rod 8 having a lower end portion inserted and disposed in the work case 4 through the through hole 4a. A rotating body 5 is attached to the lower end portion of the operation rod 8. The operation bar 8 is arranged on the same axis as the central axis facing the up-down direction of the rotating body 5 by connecting the lower end portion to the rotating body 5.

回転体５は、図２及び図４に示すように、前述したホールソーの半径Ｌ１よりも短い半径Ｒ１を有している平面視円形状の上板５ａ及び下板５ｂを備えている。これら上板５ａと下板５ｂとは、既設流体管１の切断面１ａに対して防錆塗料１０を塗布する複数（本実施例では４本）の塗料保有部１１を介して接続されている。このため、回転体５は上板５ａと下板５ｂとの間を既設流体管１内を流れる流体が通過可能となっている。   As shown in FIGS. 2 and 4, the rotating body 5 includes an upper plate 5a and a lower plate 5b having a circular shape in plan view and having a radius R1 shorter than the radius L1 of the hole saw described above. The upper plate 5a and the lower plate 5b are connected via a plurality (four in this embodiment) of paint holding portions 11 that apply the anticorrosive paint 10 to the cut surface 1a of the existing fluid pipe 1. . For this reason, the rotating body 5 can pass the fluid flowing in the existing fluid pipe 1 between the upper plate 5a and the lower plate 5b.

尚、塗料保有部１１は、上板５ａと下板５ｂとの中心を挟んで回転体５の側部で対向配置されている。また、回転体５の上下幅寸法は、既設流体管１の直径よりも長寸に形成されている。   In addition, the coating material holding | maintenance part 11 is opposingly arranged by the side part of the rotary body 5 on both sides of the center of the upper board 5a and the lower board 5b. Further, the vertical width of the rotating body 5 is longer than the diameter of the existing fluid pipe 1.

これら塗料保持部１１は、上板５ａと下板５ｂとの円周端部に上下端部が取り付けられた柱体５ｃと、回転体５の上下幅寸法と略同一の上下幅寸法を有し、柱体５ｃの側面にボルト等によって取り付けられた一対の刷毛体１１ｂと、から構成されている。これら刷毛体１１ｂは、回転体５の拡径方向への突設長さが柱体５ｃよりも長寸のＲ２に形成されており、回転体５の中心軸から刷毛体１１ｂの先端までの長さＲ１＋Ｒ２は、前述したホールソーの半径Ｌ１よりも長寸となっている。   These paint holding portions 11 have column bodies 5c having upper and lower ends attached to the circumferential ends of the upper plate 5a and the lower plate 5b, and vertical width dimensions substantially the same as the vertical width dimensions of the rotating body 5. , And a pair of brush bodies 11b attached to the side surfaces of the column body 5c with bolts or the like. These brush bodies 11b are formed to have a length R2 that is longer than the column body 5c in the projecting length of the rotating body 5 in the diameter increasing direction, and the length from the central axis of the rotating body 5 to the tip of the brush body 11b. The length R1 + R2 is longer than the radius L1 of the hole saw described above.

これら刷毛体１１ｂには、図４に示すように、予め既設流体管１の切断面１ａに塗布するための防錆塗料１０が保持されている。この防錆塗料１０は、刷毛体１１ｂで保持可能な粘性を有する樹脂系塗料である。刷毛体１１ｂは、本実施例ではウレタンゴム等により構成された板体状であるが、既設流体管１内を流れる流体の流速や物性によっては、豚や山羊等の獣毛の他、糸状のアクリル樹脂等によって構成してもよい。   As shown in FIG. 4, the brush body 11 b holds a rust preventive paint 10 to be applied to the cut surface 1 a of the existing fluid pipe 1 in advance. The rust preventive paint 10 is a resin paint having a viscosity that can be held by the brush body 11b. The brush body 11b is in the form of a plate made of urethane rubber or the like in this embodiment. However, depending on the flow velocity and physical properties of the fluid flowing in the existing fluid pipe 1, the brush body 11b is not only animal hair such as pigs or goats, but also is thread-like. You may comprise with an acrylic resin etc.

次に、操作部６について説明する。図２及び図３に示すように、操作部６は、作業ケース４の貫通孔４ａ上に配置された固定用カプラー６ａを備えており、操作棒８は、この固定用カプラー６ａと貫通孔４ａを貫通して作業ケース４内に配置されている。このため、操作棒８は貫通孔４ａと固定用カプラー６ａを貫通していることで、固定用カプラー６ａに上下方向に移動自在に保持されるようになっており、操作棒８の作業ケース４上方でのぐらつきが防止されている。尚、操作棒８が貫通する貫通孔４ａ内にはパッキンが設けられており、操作棒８と貫通孔４ａとの間は水密となっている。   Next, the operation unit 6 will be described. As shown in FIGS. 2 and 3, the operation portion 6 includes a fixing coupler 6a disposed on the through hole 4a of the work case 4, and the operation rod 8 includes the fixing coupler 6a and the through hole 4a. And is disposed in the work case 4. For this reason, since the operating rod 8 penetrates the through hole 4a and the fixing coupler 6a, the operating rod 8 is held by the fixing coupler 6a so as to be movable in the vertical direction. The wobble at the top is prevented. In addition, packing is provided in the through hole 4a through which the operation rod 8 passes, and the space between the operation rod 8 and the through hole 4a is watertight.

また、操作棒８の上端部には、水平方向を向くハンドル８ａが設けられている。このハンドル８ａの水平方向端部には、下方を向くリング体８ｂが取り付けられている。一方、作業ケース４の上面にも、ハンドル８ａと同一構成のリング体４ｂが取り付けられており、これらリング体８ｂ，４ｂにはチェーン１２等の紐体が挿通されるようになっている。   Further, a handle 8 a that faces in the horizontal direction is provided at the upper end of the operation rod 8. A ring body 8b facing downward is attached to the horizontal end of the handle 8a. On the other hand, a ring body 4b having the same configuration as that of the handle 8a is also attached to the upper surface of the work case 4, and a string body such as a chain 12 is inserted into the ring bodies 8b and 4b.

次に、前述したように構成された防錆装置の既設流体管１の切断面１ａに対する防錆動作について説明する。先ず図２に示す状態から、仕切部３の弁体３ａをスライド移動させ、筐体２内と作業ケース４内とを連通させる。このとき、既設流体管１が切断されているため、筐体２内に溜まっていた上水等の流体が作業ケース４内にまで流入する。   Next, the rust prevention operation | movement with respect to the cut surface 1a of the existing fluid pipe | tube 1 of the rust prevention apparatus comprised as mentioned above is demonstrated. First, from the state shown in FIG. 2, the valve body 3 a of the partition part 3 is slid to communicate the inside of the housing 2 and the inside of the work case 4. At this time, since the existing fluid pipe 1 is cut, fluid such as clean water that has accumulated in the housing 2 flows into the work case 4.

そして、リング体８ｂ，４ｂに挿通されているチェーン１２の両端部を図示しないレバーブロック等の機器により巻き取ることによりリング体８ｂ，４ｂ間に下向きの牽引力を発生させ、この下向きの牽引力によって操作棒８を筐体２内に押し込む。   Then, by winding both ends of the chain 12 inserted into the ring bodies 8b and 4b with a device such as a lever block (not shown), a downward traction force is generated between the ring bodies 8b and 4b. The rod 8 is pushed into the housing 2.

操作棒８が筐体２内に押し込まれると、回転体５は、図３に示すように、塗装開始位置である筐体２内の既設流体管１の対向する切断面１ａ間に配置される。このとき、回転体５の中心軸から刷毛体１１ｂの先端までの長さＲ１＋Ｒ２は、前述したホールソーの半径Ｌ１よりも長寸となっているので、回転体５は塗料保持部１１が既設流体管１の切断面１ａに対して左右側方となるように既設流体管１の対向する切断面１ａ間に配置されることが望ましい。   When the operating rod 8 is pushed into the casing 2, the rotating body 5 is disposed between the opposing cut surfaces 1a of the existing fluid pipes 1 in the casing 2, which is the coating start position, as shown in FIG. . At this time, the length R1 + R2 from the central axis of the rotating body 5 to the tip of the brush body 11b is longer than the radius L1 of the hole saw described above. It is desirable to arrange between the opposing cut surfaces 1a of the existing fluid pipe 1 so as to be on the left and right sides with respect to one cut surface 1a.

そして、回転体５を設流体管１の対向する切断面１ａ間に配置したら、リング体８ｂ，４ｂ間からチェーン１２を取り外した後に、使用者がハンドル８ａを把持することによって図３及び図４に示すように、操作棒８を白抜き矢印の方向に回動させる。このとき、操作棒８と共に回転体５も白抜き矢印の方向に回動することによって、刷毛体１１ｂが順次既設流体管１の切断面１ａに当接していき、既設流体管１の切断面１ａの全面に対しての防錆塗料の塗布がなされる。   When the rotating body 5 is disposed between the opposing cut surfaces 1a of the fluid pipe 1, the user grasps the handle 8a after the chain 12 is removed from between the ring bodies 8b and 4b, as shown in FIGS. As shown in FIG. 2, the operating rod 8 is rotated in the direction of the white arrow. At this time, the rotating body 5 together with the operation rod 8 also rotates in the direction of the white arrow, whereby the brush body 11b sequentially contacts the cut surface 1a of the existing fluid pipe 1 and the cut surface 1a of the existing fluid pipe 1 The anticorrosive paint is applied to the entire surface of the film.

既設流体管１の切断面１ａに対しての防錆塗料１０の塗布が終了したら、刷毛体１１ｂが既設流体管１の切断面１ａから離れる塗装終了位置まで操作棒８を所定角度（本実施例では塗装開始位置から１８０度）回動させる。   When the application of the rust preventive paint 10 to the cut surface 1a of the existing fluid pipe 1 is completed, the operating rod 8 is moved to a predetermined angle (this embodiment) to the paint end position where the brush body 11b is separated from the cut surface 1a of the existing fluid pipe 1. Then rotate 180 degrees from the coating start position.

そして、ハンドル８ａに図示しないクレーン車等から降ろしたワイヤー等を係止させた後、クレーンを作動させることによってハンドル８ａを作業ケース４の上方に向けて引き上げる。更に、弁体３ａをスライド移動させることによって筐体２と作業ケース４との間を閉塞する。   Then, after a wire or the like lowered from a crane truck (not shown) is locked to the handle 8a, the handle 8a is pulled up above the work case 4 by operating the crane. Furthermore, the space between the housing 2 and the work case 4 is closed by sliding the valve body 3a.

尚、作業ケース４を仕切部３から取り外す際には、作業ケース４に備えられた図示しない排水弁を開放することで作業ケース４内に溜まっている流体を外部に排出し、流体の排出完了後に取り外しを行う。更に尚、作業ケース４が取り外された後は、筐体２内の設置する弁体を内部に備えた図示しない作業ケースが仕切部３に取り付けられ、弁体３ａをスライド移動させて筐体２と作業ケースとを連通させることで、筐体２内での弁体の取り付け作業を行い、切断された既設流体管１間に弁体を設ける。   When the work case 4 is removed from the partition portion 3, the drainage valve (not shown) provided in the work case 4 is opened to discharge the fluid accumulated in the work case 4 to the outside, and the fluid discharge is completed. Remove later. Furthermore, after the work case 4 is removed, a work case (not shown) having a valve body to be installed in the housing 2 is attached to the partition portion 3, and the valve body 3a is slid to move the housing 2 The work body is connected to the work case, so that the valve body is mounted in the housing 2 and the valve body is provided between the cut existing fluid pipes 1.

以上、本実施例における防錆装置にあっては、既設流体管１を密封した筐体２と、筐体２の上部を開閉可能とする弁体３ａと、筐体２に対して弁体３ａを介して密封状に接続される作業ケース４と、作業ケース４内に配置された回転体５と、を備え、筐体２内において、不断流状態で切断された既設流体管１の切断面１ａを回転体５によって防錆塗料１０を塗布する防錆装置であって、一端が作業ケース４内で回転体５に接続され、他端が作業ケース４外の上方に配置されるとともに、作業ケース４の上下方向に移動可能且つ回動可能に枢支された操作棒８を備え、回転体５は防錆塗料１０を保有する塗料保有部１１を有し、操作棒８を下方に移動させることで回転体５を切断面１ａに対向配置するとともに、回転体５を回動させることで切断面１ａの全面に塗料保有部１１が防錆塗料１０を塗布することによって、操作棒８を操作することで既設流体管１の切断面１ａにくまなく塗装することができるので、不断流状態の既設流体管１の切断面１ａに対して容易な塗装作業によって確実な防錆を行うことができる。   As described above, in the rust prevention apparatus according to the present embodiment, the casing 2 in which the existing fluid pipe 1 is sealed, the valve body 3 a that can open and close the upper portion of the casing 2, and the valve body 3 a with respect to the casing 2. The cut surface of the existing fluid pipe 1 that is cut in an uninterrupted flow state in the housing 2, and is provided with a work case 4 that is connected in a sealed manner via a rotating body 5 and a rotating body 5 disposed in the work case 4. 1a is a rust preventive device for applying a rust preventive paint 10 by a rotating body 5, one end of which is connected to the rotating body 5 in the work case 4 and the other end is disposed above the work case 4 and The operation rod 8 is pivotally supported so as to be movable in the vertical direction of the case 4 and pivotable. The rotating body 5 has a paint holding portion 11 for holding the anticorrosive paint 10 and moves the operation rod 8 downward. As a result, the rotating body 5 is disposed opposite to the cutting surface 1a, and the rotating body 5 is rotated so as to be cut. By applying the anticorrosion paint 10 to the entire surface 1a of the surface 1a, the operation rod 8 can be used to apply the entire surface to the cut surface 1a of the existing fluid pipe 1. Reliable rust prevention can be performed on the cut surface 1a of the existing fluid pipe 1 by an easy painting operation.

また、回転体５は上板５ａ及び下板５ｂを備え、上板５ａと下板５ｂとの側端部を塗料保有部１１によって接続することで構成されるので、上板５ａと下板５ｂとの間を中空とすることができるので、回転体５が切断面１ａに対向配置されても既設流体管１の不断流状態を保ったまま塗料保有部１１による切断面１ａへの防錆塗料１０の塗布を行うことができる。   The rotating body 5 includes an upper plate 5a and a lower plate 5b, and is configured by connecting the side end portions of the upper plate 5a and the lower plate 5b with the paint holding unit 11, so that the upper plate 5a and the lower plate 5b are connected. The rust preventive paint on the cut surface 1a by the paint holding part 11 while maintaining the undisturbed flow state of the existing fluid pipe 1 even if the rotating body 5 is arranged opposite to the cut surface 1a. Ten applications can be performed.

また、回転体５は塗料保有部１１を複数有しているので、切断面１ａの同一箇所に対して複数回防錆塗料１０を塗装することができるので、切断面１ａへの防錆塗料１０の塗り残しを防ぐことができるとともに、一度防錆塗料１０を塗装した切断面１ａに再び塗装を行うことで防錆塗料１０の層を厚くし、より確実な切断面１ａの防錆を行うことができる。   Moreover, since the rotary body 5 has a plurality of paint holding portions 11, the rust preventive paint 10 can be applied to the same portion of the cut surface 1a a plurality of times, and therefore the rust preventive paint 10 on the cut surface 1a. It is possible to prevent the remaining coating from being applied, and to increase the thickness of the rust preventive paint 10 by coating the cut face 1a once coated with the rust preventive paint 10, and to more reliably prevent the cut face 1a from being rusted. Can do.

また、防錆塗料１０は、塗料保有部１１内で保持可能な粘性を有しているので、既設流体管１内の水流圧等によって塗料保有部１１から防錆塗料１０が流出してしまうことを防ぐことができる。   Further, since the rust preventive paint 10 has a viscosity that can be held in the paint holding part 11, the rust preventive paint 10 flows out of the paint hold part 11 due to a water pressure in the existing fluid pipe 1. Can be prevented.

次に、実施例２に係る防錆装置につき、図５と図６を参照して説明する。尚、前記実施例と同一構成で重複する構成を省略する。   Next, a rust prevention apparatus according to Example 2 will be described with reference to FIGS. 5 and 6. In addition, the same structure as the said Example is abbreviate | omitted.

実施例１における防錆装置は、塗布手段を回転体５とし、この回転体５の側面の複数箇所に塗料保持部１１と防錆塗料１０とを設けたが、例えば、図５に示すように、塗布手段を枠体１３として構成し、この枠体１３の両側端面に刷毛体１１ｂを設けてもよい。   In the rust preventive apparatus according to the first embodiment, the application means is the rotating body 5, and the paint holding portions 11 and the anticorrosive paint 10 are provided at a plurality of positions on the side surface of the rotating body 5. For example, as shown in FIG. The coating means may be configured as a frame 13 and the brush body 11 b may be provided on both side end surfaces of the frame 13.

具体的には、図５及び図６に示すように、枠体１３は、水平方向を向く上杆材１３ａと下杆材１３ｂとを備えており、これら上杆材１３ａと下杆材１３ｂとの水平方向の両端部を塗料保持部１１を介して接続する。尚、上杆材１３ａの平面視略中央には、操作棒８の下端部が接続されている。更に尚、本実施例で塗料保持部１１が有している刷毛体１１ｂは一条のみである。   Specifically, as shown in FIGS. 5 and 6, the frame 13 includes an upper eaves 13 a and a lower eaves 13 b facing in the horizontal direction, and the upper eaves 13 a and the lower eaves 13 b Both end portions in the horizontal direction are connected via the paint holding unit 11. In addition, the lower end part of the operation stick | rod 8 is connected to the substantially planar center of the upper collar 13a. Furthermore, the brush body 11b which the coating material holding part 11 has in this embodiment is only one line.

そして、既設流体管１の両切断面１ａに防錆塗料１０を塗布するには、実施例１と同様に、リング体８ｂ，４ｂ間に挿通されたチェーン１２の両端部をレバーブロック等の機器により巻き取ることで既設流体管１の両切断面１ａ間に枠体１３を配置し、リング体８ｂ，４ｂ間からチェーン１２を取り外した後に使用者がハンドル８ａを水平回動させて既設流体管１の両切断面１ａに刷毛体１１ｂによって防錆塗料１０を塗布する。   And in order to apply the anticorrosion paint 10 to both the cut surfaces 1a of the existing fluid pipe 1, like the first embodiment, both ends of the chain 12 inserted between the ring bodies 8b and 4b are connected to a device such as a lever block. The frame body 13 is disposed between the two cut surfaces 1a of the existing fluid pipe 1 by winding, and after the chain 12 is removed from between the ring bodies 8b and 4b, the user horizontally rotates the handle 8a and the existing fluid pipe The anticorrosive paint 10 is applied to both the cut surfaces 1a of 1 by the brush body 11b.

以上、本実施例における防錆装置にあっては、枠体１３は水平方向を向く上杆材１３ａ及び下杆材１３ｂを備え、上杆材１３ａと下杆材１３ｂとの水平方向端部を塗料保有部１１によって接続することで構成されるので、枠体１３を簡素な構成とすることができ、上杆材１３ａと下杆材１３ｂとの間を中空とすることができるので、枠体１３が切断面１ａに対向配置されても既設流体管１の不断流状態を保ったまま塗料保有部１１による切断面１ａへの防錆塗料１０の塗布を行うことができる。また、塗料保有部１１を板体に接続して塗布手段を構成する場合よりも筐体２内に充満した流体から受ける垂直方向の抵抗が小さくなるので、枠体１３を切断面１ａに容易に対向配置させることができる。   As described above, in the rust prevention apparatus according to the present embodiment, the frame body 13 includes the upper collar material 13a and the lower collar material 13b facing in the horizontal direction, and the horizontal end portions of the upper collar material 13a and the lower collar material 13b are provided. Since it is configured by being connected by the paint holding unit 11, the frame body 13 can have a simple configuration, and the space between the upper collar material 13a and the lower collar material 13b can be made hollow. Even if 13 is disposed to face the cut surface 1a, the anticorrosive paint 10 can be applied to the cut surface 1a by the paint holding part 11 while maintaining the undisturbed flow state of the existing fluid pipe 1. Further, since the resistance in the vertical direction received from the fluid filled in the housing 2 is smaller than when the coating material holding portion 11 is connected to the plate body to constitute the coating means, the frame body 13 can be easily attached to the cut surface 1a. It can be arranged oppositely.

次に、実施例３に係る防錆装置につき、図７から図９を参照して説明する。尚、前記実施例に示される構成部分と同一構成部分に付いては同一符号を付して重複する説明を省略する。   Next, a rust prevention apparatus according to Example 3 will be described with reference to FIGS. It should be noted that the same components as those shown in the above-described embodiment are denoted by the same reference numerals and redundant description is omitted.

実施例１及び実施例２では、既設流体管１の両切断面１ａ間に塗布手段を配置した後に塗布手段を水平回動させることで切断面１ａに防錆塗料１０を塗布したが、例えば、図７に示すように、既設流体管１がチェーンソー等の切削工具によって垂直に切断された場合には、塗布手段を垂直回動するようにして切断面１ｂに防錆塗料１０を塗布するようにしてもよい。   In Example 1 and Example 2, the anticorrosion paint 10 was applied to the cut surface 1a by horizontally rotating the application unit after disposing the application unit between the two cut surfaces 1a of the existing fluid pipe 1. For example, As shown in FIG. 7, when the existing fluid pipe 1 is cut vertically by a cutting tool such as a chain saw, the rust preventive paint 10 is applied to the cut surface 1b by rotating the applying means vertically. May be.

具体的には、図７から図９に示すように、操作棒８の下端部には、既設流体管１の軸方向を向く基板１４が取り付けられている。この基板１４の既設流体管１の軸方向の両端部には、塗布手段としてのローラ１５が垂直回動可能に枢支されている。   Specifically, as shown in FIGS. 7 to 9, a base plate 14 facing the axial direction of the existing fluid pipe 1 is attached to the lower end portion of the operation rod 8. Rollers 15 as application means are pivotally supported at both ends in the axial direction of the existing fluid pipe 1 of the substrate 14 so as to be vertically rotatable.

これらローラ１５は、既設流体管１の直径と略同寸の左右幅寸法を有している。また、ローラ１５の周面には、合成樹脂材等で構成された多孔質且つ柔軟性を有するスポンジ材１５ａが巻回されており、防錆塗料１０はこのスポンジ材１５ａ吸入された状態で保持されている。つまりスポンジ材１５ａは本実施例における塗料保有部を構成している。   These rollers 15 have a lateral width dimension that is substantially the same as the diameter of the existing fluid pipe 1. Further, a porous and flexible sponge material 15a made of a synthetic resin material or the like is wound around the peripheral surface of the roller 15, and the rust preventive paint 10 is held in a state where the sponge material 15a is inhaled. Has been. That is, the sponge material 15a constitutes the paint holding part in this embodiment.

そして、既設流体管１の両切断面１ｂに防錆塗料１０を塗布するには、実施例１と同様に、リング体８ｂ，４ｂ間に挿通されたチェーン１２の両端部をレバーブロック等の機器により巻き取り、操作棒８を筐体２内に押し込む。このとき、両ローラ１５が既設流体管１の両切断面１ｂに上端部側から順次当接していき、ローラ１５が両切断面１ｂの下端部まで下方に移動しながら垂直回動することで切断面１ｂにスポンジ材１５ａに吸入されていた防錆塗料１０が塗布されていく。   And in order to apply the anticorrosion paint 10 to both the cut surfaces 1b of the existing fluid pipe 1, like the first embodiment, both ends of the chain 12 inserted between the ring bodies 8b and 4b are connected to a device such as a lever block. To wind the operating rod 8 into the housing 2. At this time, both rollers 15 sequentially come into contact with both cut surfaces 1b of the existing fluid pipe 1 from the upper end side, and the rollers 15 rotate vertically while moving downward to the lower end portions of both cut surfaces 1b. The rust preventive paint 10 sucked in the sponge material 15a is applied to the surface 1b.

操作棒８が筐体２内に押し込まれることで既設流体管１の両切断面１ｂの防錆塗料１０の塗布が終了したら、再び実施例１と同様に、ハンドル８ａに図示しないクレーン車等から降ろしたワイヤー等を係止させた後、クレーンを作動させることによってハンドル８ａを作業ケース４の上方に向けて引き上げる。更に、弁体３ａをスライド移動させることによって筐体２と作業ケース４との間を閉塞する。   When the operation rod 8 is pushed into the housing 2 and the application of the anticorrosive paint 10 to both the cut surfaces 1b of the existing fluid pipe 1 is completed, the handle 8a is again connected to the handle 8a from a crane vehicle (not shown). After the lowered wire or the like is locked, the handle 8a is pulled up above the work case 4 by operating the crane. Furthermore, the space between the housing 2 and the work case 4 is closed by sliding the valve body 3a.

このとき、両ローラ１５が再び既設流体管１の両切断面１ｂに下端部側から順次当接していき、既設流体管１の両切断面１ｂに重ね塗りがなされる。このため、切断面１ｂに対する防錆塗料１０の層が厚くなるので、切断面１ｂに対する防錆をより確実に行うことができる。   At this time, both rollers 15 again sequentially come into contact with the two cut surfaces 1b of the existing fluid pipe 1 from the lower end side, and the two cut surfaces 1b of the existing fluid pipe 1 are overcoated. For this reason, since the layer of the antirust coating 10 with respect to the cut surface 1b becomes thick, the antirust with respect to the cut surface 1b can be performed more reliably.
