Description

本発明は分岐器等補修用ボルト及びそれを用いた補修方法、より詳細には、鉄道線路の主として分岐器において、緩んだ犬クギ類に代え、タイプレート並びにレールを枕木に固定するための分岐器等補修用ボルト及びそれを用いた補修方法に関する。   The present invention relates to a repair bolt and a repair method using the same, and more particularly to a branch for fixing a tie plate and a rail to a sleeper in place of a loose dog cedar in a main branch of a railway line. The present invention relates to a repair bolt and the repair method using the same.

鉄道線路においては、軌道を2つ以上の軌道に分ける軌道構造である分岐器が、一番過酷な条件で使用されていると考えられる。この分岐器においては、木枕木や合成枕木上にレール締結用の分岐タイプレートが、犬クギやネジクギで固定される。しかるに、犬クギやネジクギは、列車通過時の振動圧や横圧による荷重を受け続けることにより、初期の設定締結力の保持ができなくなって緩み、その緩みは床板オイルがクギ類に付着することによって増大する。このようなクギ類の緩みは、各構成部の損傷劣化を助長し、また、騒音の原因ともなっている。   In railroad tracks, it is considered that a branching device having a track structure that divides a track into two or more tracks is used under the harshest conditions. In this branching device, a branch tie plate for fastening a rail is fixed on a wooden sleeper or a synthetic sleeper by a dog shoe or a screw shoe. However, dog nails and screw nails will continue to receive loads due to vibration pressure and lateral pressure when passing through the train, so that the initial set fastening force can no longer be maintained and loosened, and the floor oil will adhere to nails. Increased by Such loosening of the cucumbers promotes damage deterioration of each component and also causes noise.

上記分岐器のレール締結装置の一部である犬クギ類の補修作業の効率化、及び、保守周期の延伸化を企図した補修用ボルトが提案されている(特許文献1)。これは、図6及び図7に示すように、ボルト31の上下に、普通ネジの上側ナット32と逆ネジの下側ナット33を組み付け、下側ナット33に被さるようにしてゴムチューブ34をボルト31に被装したものである。
特願2002−300917号
There has been proposed a repair bolt intended to improve the efficiency of repair work for dog cucumbers, which are a part of the rail fastening device of the branching device, and to extend the maintenance cycle (Patent Document 1). As shown in FIGS. 6 and 7, the upper nut 32 of a normal screw and the lower nut 33 of a reverse screw are assembled to the upper and lower sides of the bolt 31, and the rubber tube 34 is bolted so as to cover the lower nut 33. 31 is covered.
Japanese Patent Application No. 2002-300197

かかる構成において、ボルト31を回転させると、ターンバックルと同様の作用にて、下側ナット33が上側ナット32に近付いていくため、それに被せられているゴムチューブ34が上側ナット32との間で押し縮められて、その周面が外方向に膨隆する。   In such a configuration, when the bolt 31 is rotated, the lower nut 33 approaches the upper nut 32 by the same action as the turnbuckle, so that the rubber tube 34 placed on the nut 31 is between the upper nut 32 and the lower nut 33. When compressed, the peripheral surface bulges outward.

この補修用ボルトを使用する場合は、枕木35からネジクギを抜き取り、抜き取った後の円孔39をドリルで拡径化する。そして、タイプレート36を載置し、タイプレート36から枕木35にかけてボルト31を打ち込み、次いでボルト31を回転させると(図7(A))、ゴムチューブ34が孔壁に強固に密着し、ボルトは抜けなくなる(図7(B))。その後タイプレート36部分にゴムカラー37を嵌め付け、固定ナット38を締め付けてタイプレート36を固定する(図7(C))。   When using this repair bolt, the screw holes are extracted from the sleeper 35, and the diameter of the circular hole 39 after the extraction is increased by a drill. When the tie plate 36 is placed, the bolt 31 is driven from the tie plate 36 to the sleeper 35, and then the bolt 31 is rotated (FIG. 7A), the rubber tube 34 is firmly attached to the hole wall, and the bolt Cannot be removed (FIG. 7B). Thereafter, a rubber collar 37 is fitted into the tie plate 36 and the fixing nut 38 is tightened to fix the tie plate 36 (FIG. 7C).

上記補修用ボルトの場合、設置に際して枕木のクギ抜き穴を拡径化すると共に、ボルト31を緊締しなければならないために作業に手間がかかり、また、ゴムチューブ34が振動等の過酷な条件下に晒されて劣化しやすく、その劣化は直ちにボルトの緩みにつながる。   In the case of the above-described repair bolt, the diameter of the nail hole of the sleeper is increased at the time of installation, and the bolt 31 has to be tightened. Therefore, the work is troublesome, and the rubber tube 34 is subjected to severe conditions such as vibration. It is easy to deteriorate by being exposed to, and the deterioration immediately leads to loosening of the bolt.

また、特に木枕木の場合には、当接する鉄製のタイプレート36が枕木35にくい込みやすく、くい込んだ場合には、固定ナット38によるタイプレート36の締付けが甘くなって、緩む。   In particular, in the case of a wooden sleeper, the iron tie plate 36 that comes into contact with the sleeper 35 is easily inserted, and when it is inserted, the tightening of the tie plate 36 by the fixing nut 38 becomes sweet and loosens.

本発明は、上述したような従来の分岐器等補修用ボルト並びに補修方法における欠点に鑑みてなされたもので、犬クギ類との交換による補修作業が容易で手間がかからず、補修作業の効率化が図れ、施工後のボルトの緩みが極力防止されるために、列車走行時の騒音が防止されると共に、保守周期を延伸し得る分岐器等補修用ボルト及びそれを用いた補修方法を提供することを課題とする。   The present invention has been made in view of the drawbacks of the above-mentioned conventional repairing bolts for branching devices and the like and the repairing method, and the repairing work by exchanging with the dog cucumber is easy and trouble-free. To improve efficiency and prevent loosening of bolts after construction as much as possible, while preventing noise during train travel, a repair bolt using a repair bolt and the like that can extend the maintenance cycle, etc. The issue is to provide.

本発明はまた、一旦打ち込んだ後に、引き抜き可能にした分岐器等補修用ボルト及びそれを用いた補修方法を提供することを課題とする。   Another object of the present invention is to provide a repair bolt such as a branching device that can be pulled out after being driven once, and a repair method using the same.

上記課題を解決するための本発明に係る分岐器等補修用ボルトは、アンカーと、前記アンカーに一部を残して被装される前記アンカーよりも軟質資材製の外装筒とから成り、前記アンカーは上部に固定用ナットをネジ付けるためのオネジ部を有すると共に、下部に拡開機能部を備え、前記外装筒は枕木における犬クギ類の抜き穴に対応する形状とされ、前記アンカーの下部拡開に伴なって前記外装筒の下部も拡開して前記抜き穴の壁面にくい込み可能にして成ることを特徴とする。   A bolt for repairing a branching device or the like according to the present invention for solving the above-mentioned problem comprises an anchor and an outer cylinder made of a softer material than the anchor to be mounted while leaving a part of the anchor. Has a male screw part for screwing a fixing nut at the upper part, and has an expansion function part at the lower part, and the outer cylinder is shaped to correspond to a hole in a sleeper in a sleeper, and the lower part of the anchor is enlarged. Along with the opening, the lower part of the outer cylinder is also expanded so that the wall surface of the punched hole can be inserted.

前記アンカーは、上面から中間部まで芯棒が挿入される芯棒挿入孔が形成され、下部がすり割りを入れることによって複数に分割され、前記芯棒挿入孔の内底面中心から下面に抜ける細孔が形成されたものとし、好ましくは、前記アンカー上に、中心部に前記芯棒の頸部以外の部分を挿通させる芯棒挿通口を形成した引抜板を配置する。   The anchor is formed with a core rod insertion hole into which a core rod is inserted from the upper surface to the middle portion, and the lower portion is divided into a plurality of portions by slitting, and the anchor extends from the center of the inner bottom surface of the core rod insertion hole to the lower surface. It is assumed that a hole is formed, and preferably, a drawing plate in which a core bar insertion opening for inserting a portion other than the neck portion of the core bar in the center is formed on the anchor.

あるいは、前記アンカーは、下部がすり割りを入れることによって複数に分割されたスリーブと、上部に前記オネジ部を有し、下部にテーパ部を有していて前記スリーブに下方から挿し込まれるテーパ付きボルトとで構成されるものとするとし、好ましくは、前記スリーブは、上端にフランジが形成されたものとする。   Alternatively, the anchor has a sleeve that is divided into a plurality of parts by slitting the lower part and the male screw part at the upper part, and has a tapered part at the lower part and is tapered from below into the sleeve. It is assumed that the sleeve is constituted by a bolt, and preferably, the sleeve has a flange formed at the upper end.

好ましくは、各アンカーのすり割り部に、環状凹凸部を設ける。更に好ましくは、前記外装筒はアンカーよりも軟質のアルミニウム製又はプラスチック製とし、その下部拡開部に予め長さ方向に延びる切り込みを入れる。前記外装筒は、その成形時にアンカーと一体化することができる。外装筒の下面は閉塞してもよいし、開放してもよい。   Preferably, an annular concavo-convex portion is provided in the slit portion of each anchor. More preferably, the outer cylinder is made of aluminum or plastic which is softer than the anchor, and a cut extending in the length direction is made in advance in the lower expanded portion. The outer cylinder can be integrated with the anchor during molding. The lower surface of the outer cylinder may be closed or opened.

また、上記課題を解決するための本発明に係る分岐器等補修用ボルトを用いた補修方法は、上記補修用ボルトを用いてタイプレートを枕木上に固定するに当たり、タイプレートと枕木との間に、防振材を挟み込むことを特徴とする。   Moreover, the repair method using the repair bolts such as a branching device according to the present invention for solving the above-described problem is that between fixing the tie plate on the sleeper using the repair bolt, In addition, a vibration-proof material is sandwiched between the two.

本発明に係る補修用ボルト及びそれを用いた補修方法によれば、分岐器等における犬クギ類の補修作業がクギ抜き穴の拡開加工が不要のために容易で手間がかからないものとなり、補修作業の効率化が図れ、施工後のボルトの緩みが起こりにくく、列車走行時の騒音が防止されると共に、保守周期を延伸することが可能となる。   According to the repair bolt and the repair method using the same according to the present invention, the repair work of the dog nails in the branching device and the like is easy and hassle-free because the expansion process of the hole for the nails is unnecessary, and repair is performed. The efficiency of the work can be improved, the bolts are less likely to loosen after construction, noise during train traveling is prevented, and the maintenance cycle can be extended.

請求項3及び請求項5に記載の発明においては、一旦打込んだ補修用ボルトの引き抜きが可能という効果がある。   In the inventions according to claims 3 and 5, there is an effect that the repair bolt once driven in can be pulled out.

本発明の好ましい実施の形態について図面に依拠して説明する。本発明に係る補修用ボルトは、アンカー1と、アンカー1に一部を残して被装されるアンカー1よりも軟質資材製の外装筒8とから成る。アンカー1は、上部に固定用ナット6をネジ付けるためのオネジ部3を有すると共に、下部に拡開機能部を備え、外装筒8は枕木20における犬クギ類の抜き穴21に対応する形状とされ、アンカー1の下部拡開に伴なって外装筒8の下部も内方から押し拡げられて拡開し、抜き穴21の壁面にくい込む。   A preferred embodiment of the present invention will be described with reference to the drawings. The repair bolt according to the present invention includes an anchor 1 and an outer cylinder 8 made of a softer material than the anchor 1 that is mounted on the anchor 1 while leaving a part. The anchor 1 has a male screw portion 3 for screwing a fixing nut 6 at the upper portion and an expansion function portion at the lower portion, and the outer cylinder 8 has a shape corresponding to a hole 21 for a dog cedar in the sleeper 20. As the anchor 1 expands downward, the lower portion of the outer tube 8 is also expanded from the inside to expand, and the wall surface of the punched hole 21 is not easily inserted.

アンカー1の下部拡開機能部の構成としては、図1乃至図6に示すタイプのもの(第1及び第2の実施形態)と、図7及び図8に示すタイプのもの(第3の実施形態)とが考えられる。   As the structure of the lower expanding function portion of the anchor 1, the type shown in FIGS. 1 to 6 (first and second embodiments) and the type shown in FIGS. 7 and 8 (third embodiment) Form).

図1乃至図4に示す第1の実施形態における補修用ボルトのアンカー1は、上部にオネジ部3が設けられ、上面から中間部まで芯棒挿入孔4が形成され、下部がすり割り5を入れることによって複数に分割されたネジ杆2と、オネジ部3にネジ付けられる固定用ナット6と、芯棒挿入孔4に挿入される芯棒7とから成り、ネジ杆2にその上部を残して外装筒8が被装される。   The anchor 1 of the repair bolt in the first embodiment shown in FIGS. 1 to 4 is provided with a male screw portion 3 at the upper portion, a core rod insertion hole 4 is formed from the upper surface to the middle portion, and the lower portion has a slit 5. The screw rod 2 divided into a plurality of parts, a fixing nut 6 to be screwed to the male screw portion 3, and a core rod 7 to be inserted into the core rod insertion hole 4, leaving the upper portion of the screw rod 2. The outer cylinder 8 is covered.

ネジ杆2の芯棒挿入孔4の内底4aは砲弾状又は錐状とし、その中心からネジ杆2の下面にかけて、細孔9を貫設する(図3参照)。各すり割り5は、この細孔9に達するように形成される。なお、すり割り5形成部に、環状凹凸部10を設けることもある。その場合、外装筒8の内面がその凹部分にくい込むため、ネジ杆2が外装筒8から抜けにくくなる。   The inner bottom 4a of the core rod insertion hole 4 of the screw rod 2 is bullet-shaped or conical, and the pore 9 extends through the center to the lower surface of the screw rod 2 (see FIG. 3). Each slot 5 is formed to reach the pores 9. In addition, the annular uneven | corrugated | grooved part 10 may be provided in the slot 5 formation part. In that case, since the inner surface of the outer cylinder 8 is less likely to be recessed, the screw rod 2 is less likely to be removed from the outer cylinder 8.

外装筒8は、アンカー1よりも軟質資材製(通例アルミニウム製又はプラスチック製)で、枕木20における犬クギ類の抜き穴21に対応する形状、即ち、先端が尖った円筒形(図1右側、図2左側)又は四角筒形(図1左側、図2右側)に成形される。外装筒8は、図1に示すように底面を閉塞することとしてもよいし、図4に示すように底面を開放するように成形することとしてもよい。   The outer cylinder 8 is made of a softer material (usually made of aluminum or plastic) than the anchor 1 and has a shape corresponding to the hole 21 of the dog nail in the sleeper 20, that is, a cylindrical shape with a sharp tip (right side of FIG. 2 left side) or a square cylinder (left side of FIG. 1, right side of FIG. 2). The outer cylinder 8 may be closed at the bottom as shown in FIG. 1, or may be molded so as to open the bottom as shown in FIG.

外装筒8の壁厚は、後述するネジ杆2の作用により、内部から加圧されることによって破断可能な厚さ(具体的には数ミリメートル)とされる。この破断を容易にするために、外装筒8の下部拡開部に、予め長さ方向に延びる切り込み10を複数本(通例2乃至8本)入れておくこともある(図4参照)。なお、外装筒8が四角筒の場合、アンカー1の全周に密着するようにしてもよいし(図4(B))、全周の肉厚を同じにすることにより4隅に空隙部を残すこととしてもよい(図4(C))。   The wall thickness of the outer cylinder 8 is set to a thickness (specifically, several millimeters) that can be broken by being pressurized from the inside by the action of a screw rod 2 described later. In order to facilitate this breakage, a plurality of cuts 10 (typically 2 to 8) extending in the length direction may be provided in advance in the lower expanded portion of the outer cylinder 8 (see FIG. 4). In addition, when the exterior cylinder 8 is a square cylinder, you may make it closely_contact | adhere to the perimeter of the anchor 1 (FIG.4 (B)), and by making the thickness of a perimeter the same, a space | gap part is set at four corners. It may be left (FIG. 4C).

ネジ杆2は、別途成形した外装筒8に後から挿入することとしてもよいし、金属インサート成形等の成形法により、外装筒8の成形と同時にネジ杆2に被装するようにしてもよい。   The screw rod 2 may be inserted later into a separately molded outer cylinder 8 or may be mounted on the screw rod 2 simultaneously with the molding of the outer cylinder 8 by a molding method such as metal insert molding. .

次いで、上記構成の補修用ボルト1の作用、並びに、それを用いた分岐器の補修方法について説明する。この補修に際し、枕木20に生成される抜き穴21は、中のゴミ等を取り出すだけで、拡径等の加工は必要ない。本発明に係る補修方法においては、枕木20上に載置するタイプレート22の下に、板状の防振材23を挟み込む。   Next, the operation of the repair bolt 1 having the above-described configuration and the branching device repair method using the same will be described. At the time of this repair, the punched hole 21 generated in the sleeper 20 only takes out dust and the like inside, and processing such as diameter expansion is not necessary. In the repair method according to the present invention, a plate-shaped vibration isolator 23 is sandwiched under a tie plate 22 placed on a sleeper 20.

防振材23としては、例えば、オーストリア国、ゲツナー ヴェルクストッフ社の多孔性ポリウレタン・エラストマー(商標名 Sylomer,Sylodyn)が好適である。   As the vibration isolator 23, for example, porous polyurethane elastomer (trade name: Sylomer, Sylodyn) of Getzner Werkstoff, Austria is suitable.

補修用ボルト1は、タイプレート22及び防振材23を通して抜き穴21内に押し入れる(図2)。そして、芯棒7をハンマーで打叩すると、芯棒7は芯棒挿入孔4から細孔9へ進入し、細孔9を押し拡げる(図3の左端に示すもの参照)。これにより、ネジ杆2の下部がすり割り5部分から拡がり、その周囲の外装筒8が内方から押し拡げられて適宜破断し、抜き穴21の壁面にくい込む。その結果、補修用ボルト1は容易には抜けなくなる。   The repair bolt 1 is pushed into the punched hole 21 through the tie plate 22 and the vibration isolator 23 (FIG. 2). When the core rod 7 is struck with a hammer, the core rod 7 enters the pore 9 from the core rod insertion hole 4 and expands the pore 9 (see the one shown at the left end of FIG. 3). As a result, the lower portion of the screw rod 2 expands from the slit 5 portion, the surrounding cylinder 8 is pushed and expanded from the inside, and is appropriately broken, so that the wall surface of the punched hole 21 is not easily inserted. As a result, the repair bolt 1 cannot be easily removed.

その際固定用ナット6は未だ緩んだ状態であるので、これを緊締して作業完了となる。タイプレート22は、直接ではなく、防振材23を介して枕木20上に固定されるので、枕木20にくい込むことはなく、しかも、防振材23の防振作用によって衝撃荷重が緩和されるために、固定用ナット6が短期間の内に緩むということはない。また、防振材23の作用で列車通過時の騒音も軽減される。   At that time, the fixing nut 6 is still loosened, and is tightened to complete the operation. Since the tie plate 22 is fixed on the sleeper 20 through the vibration isolator 23, not directly, the sleeper 20 is not inserted into the sleeper 20 and the impact load is reduced by the vibration isolating action of the vibration isolator 23. Therefore, the fixing nut 6 is not loosened within a short period of time. Moreover, the noise at the time of passing a train is also reduced by the action of the vibration isolator 23.

図5及び図6に示す第2の実施形態は、上記実施形態のものを抜取り可能にしたものである。この実施形態は、上記構成に対し、更に引抜板17を付加したもので、他の構成は同じである。引抜板17は、中央に芯棒挿通口18を形成した円板で、芯棒7は芯棒挿通口18に挿通されるが、その頸部は芯棒挿通口18を抜けない。引抜板17は、ネジ杆2の上に配置される。   In the second embodiment shown in FIGS. 5 and 6, the above embodiment can be extracted. In this embodiment, a drawing plate 17 is further added to the above configuration, and the other configurations are the same. The drawing plate 17 is a disc having a core rod insertion port 18 formed in the center. The core rod 7 is inserted into the core rod insertion port 18, but the neck portion does not pass through the core rod insertion port 18. The drawing plate 17 is disposed on the screw rod 2.

この実施形態の場合も、芯棒7をハンマーで打叩してその先端部を細孔9内に強制的に進入させ、ネジ杆2の下部並びに外装筒8の下部を内方から押し拡げて、抜き穴21の壁面にくい込ませる。この場合の芯棒7は、引抜板17があるために、その頸部はオネジ部3内に埋入せず、引抜板17上に位置する。   Also in this embodiment, the core rod 7 is struck with a hammer to force its tip portion into the pore 9, and the lower portion of the screw rod 2 and the lower portion of the outer cylinder 8 are pushed and expanded from the inside. , Make the wall of the punched hole 21 difficult. In this case, since the core rod 7 has the extraction plate 17, the neck portion is not embedded in the male screw portion 3 and is positioned on the extraction plate 17.

この実施形態に係る補修用ボルトを抜き取る必要が生じた場合は、例えば、図9に示すようなレール吊上機25を用いて引抜く。その引抜きに際しては先ず、レール吊上機25の吊上チェーン26の先端に、引抜板17を引掛ける係止手段を取り付け、これを引抜板17に係止させて引抜板17を引上げる。かくして引抜板17と共に、頸部がその芯棒挿通口18の周縁部に引掛っている芯棒7が引上げられ、ネジ杆2から抜ける。それによりネジ杆2の下部が、芯棒7によってもたらされていた拡開力から解放される。   When it becomes necessary to pull out the repair bolt according to this embodiment, for example, it is pulled out using a rail lifting machine 25 as shown in FIG. At the time of the drawing, first, a locking means for hooking the pulling plate 17 is attached to the tip of the lifting chain 26 of the rail hoisting machine 25, and the pulling plate 17 is pulled up by locking this with the pulling plate 17. Thus, the core rod 7 whose neck portion is hooked to the peripheral edge portion of the core rod insertion port 18 is pulled up together with the pulling plate 17 and is removed from the screw rod 2. As a result, the lower part of the screw rod 2 is released from the spreading force provided by the core rod 7.

次いで、露出状態にて突出しているネジ杆2のオネジ部3に、例えば図10に示すようなオネジ部3に対する螺合手段を有するアイナット27をネジ付け、これに吊上チェーン26の先端のフック28を引掛けて、アイナット27を介してネジ杆2並びにこれに一体となった外装筒8を、抜き穴21から抜き取る。   Next, for example, an eye nut 27 having a screwing means for the male screw portion 3 as shown in FIG. 10 is screwed onto the male screw portion 3 of the screw rod 2 protruding in an exposed state, and a hook at the tip of the lifting chain 26 is attached thereto. 28, the screw rod 2 and the exterior cylinder 8 integrated with the screw rod 2 are extracted from the extraction hole 21 through the eye nut 27.

図7及び図8に示す第3の実施形態における補修用ボルトにおいては、外装筒8内に挿入されるアンカー1aは、スリーブ12と、スリーブ12内に挿通されるテーパ付きボルト13とで構成される。スリーブ12は、下部に複数のすり割り5aを有し、上面にフランジ14を備える。また、テーパ付きボルト13は、上部に固定用ナット6をネジ付けるオネジ部3aを有し、下端部に、テーパ部15を有する。外装筒8は、上記実施形態の場合と同じ構成である。   In the repair bolt in the third embodiment shown in FIGS. 7 and 8, the anchor 1 a inserted into the outer cylinder 8 is composed of a sleeve 12 and a tapered bolt 13 inserted into the sleeve 12. The The sleeve 12 has a plurality of slits 5a at the lower portion and a flange 14 on the upper surface. Moreover, the taper bolt 13 has a male screw part 3a to which the fixing nut 6 is screwed at the upper part, and has a taper part 15 at the lower end part. The outer cylinder 8 has the same configuration as in the above embodiment.

この補修用ボルトの場合は、上記補修用ボルトの場合と同様にして抜き穴21に押し込んだ後、打込み治具を用いてスリーブ12を打込む。これにより、テーパ付きボルト13のテーパ部15が、すり割り5aを設けたスリーブ12の下部内に進入し、その部分をラジアル方向に加圧する。その結果、スリーブ12の下部はそのすり割り5aから拡開し、第1の実施形態の場合と同様に、外装筒8を破断させて抜き穴21の壁面にくい込ませるよう作用する。   In the case of this repair bolt, the sleeve 12 is driven using a driving jig after being pushed into the punched hole 21 as in the case of the repair bolt. Thereby, the taper part 15 of the taper bolt 13 enters the lower part of the sleeve 12 provided with the slit 5a, and presses the part in the radial direction. As a result, the lower portion of the sleeve 12 expands from the slit 5a, and acts to break the outer cylinder 8 so that the wall surface of the punched hole 21 is not easily inserted, as in the case of the first embodiment.

この補修用ボルトの場合は、スリーブ12のフランジ14が露出しているので、上記レール吊上機25を利用し、その吊上チェーン26先端の係止手段にフランジ14を引掛けて引上げることにより、抜き取りが可能である。   In the case of this repair bolt, since the flange 14 of the sleeve 12 is exposed, the rail lifting machine 25 is used and the flange 14 is hooked on the locking means at the tip of the lifting chain 26 and pulled up. Can be extracted.

このように本発明に係る補修用ボルト及びそれを用いた補修方法によれば、補修作業の簡易化及びそれに伴なうローコスト化が図れ、補修用ボルトと枕木の結合が強固となって緩みにくくなるので、保守作業間隔の延伸化が可能となる。   As described above, according to the repair bolt and the repair method using the repair bolt according to the present invention, the repair work can be simplified and the cost can be reduced, and the repair bolt and the sleeper are firmly connected to each other and are not easily loosened. Therefore, the maintenance work interval can be extended.
