Description

本発明は、特に逸脱防止ガードの付設によるマクラギの剛性増大を抑え、マクラギをバラスト道床やコンクリート路盤に直接支障なく敷設できるようにしたマクラギの逸脱防止ガードおよび当該逸脱防止ガードを備えた逸脱防止ガード付きマクラギに関するものである。   The present invention relates to a sleeper departure prevention guard and a departure prevention guard equipped with the departure prevention guard, which suppresses an increase in the rigidity of sleepers, particularly due to the attachment of a departure prevention guard, and allows the sleepers to be laid directly on a ballast roadbed or a concrete roadbed. It is about the sleeper with.

走行中の列車が地震などで脱線して対向列車と衝突したり、高架橋から転落するといった事態になれば、多くの負傷者がでて大惨事になることは容易に想像できることであり、新潟県中越地震における上越新幹線の列車脱線を契機に、走行中の列車の安全性が大きな課題になっている。   It is easy to imagine that if a running train derails due to an earthquake etc. and collides with an oncoming train or falls from a viaduct, many injured people will become catastrophic. As a result of the train derailment of the Joetsu Shinkansen in the Chuetsu Earthquake, the safety of running trains has become a major issue.

従来、列車の脱線を防止する方法として、マクラギに当該マクラギの上に敷設されたレールの内側または外側に沿って逸脱防止ガードを取り付ける方法が知られており、上越新幹線の列車脱線事故を受けて、特に注目されてきている。
特開２００４−３２４２４５号公報 特開２００４−３２４２８７号公報 Conventionally, as a method of preventing train derailment, there has been known a method of attaching a departure prevention guard to the sleeper along the inside or outside of the rail laid on the sleeper. In response to the train derailment accident of the Joetsu Shinkansen Has been attracting particular attention.
JP 2004-324245 A JP 2004-324287 A

逸脱防止ガードは、一般に鋼材または鉄筋コンクリートによってマクラギと一体に形成されるため、逸脱防止ガードを備えたマクラギは逸脱防止ガードを有することで曲げ剛性が大きい。   Since the departure prevention guard is generally formed integrally with sleepers by steel or reinforced concrete, the sleepers provided with the departure prevention guard have a large bending rigidity by having the departure prevention guard.

このため、バラスト道床やコンクリート路盤に、特にラダーマクラギを敷設するに際して、軌きょうを持ち上げ、バラストの突き固めや冶具による整正を行う場合、マクラギの曲げ剛性が大き過ぎるとバラスト道床への変位・追従がほとんど無いか非常に小さいため、マクラギの敷設・整正が非常に困難になる等の課題があった。   For this reason, when laying ladder sleepers on the ballast roadbed and concrete roadbed, especially when lifting the rails and performing ballast tamping or leveling with jigs, if the bending stiffness of the sleepers is too large, the displacement to the ballast roadbed Since there is little or very little follow-up, there have been problems such as making it difficult to lay and correct sleepers.

本発明は、以上の課題を解決するためになされたもので、特に逸脱防止ガードの付設によるマクラギの剛性増大を抑えて、マクラギをバラスト道床やコンクリート路盤にも支障なく敷設できるようにしたマクラギの逸脱防止ガードおよび当該逸脱防止ガードを備えた逸脱防止ガード付きマクラギを提供することを目的とする。   The present invention has been made to solve the above-described problems. In particular, a sleeper of the sleeper that can suppress the increase in rigidity of the sleeper by attaching a departure prevention guard, and can lay sleeper on a ballast roadbed or a concrete roadbed without any trouble. An object is to provide a departure prevention guard and a sleeper with a departure prevention guard provided with the departure prevention guard.

請求項１記載のマクラギの逸脱防止ガードは、マクラギに当該マクラギに敷設された一対のレールの内側若しくは外側に沿って設けられたマクラギの逸脱防止ガードであって、前記レールの長手方向に所定間隔おきに形成されたスリットと前記レールの長手方向に連続して挿通された線状部材を備えてなることを特徴とするものである。   The sleeper departure prevention guard according to claim 1, wherein the sleeper departure prevention guard is provided along the inner or outer side of a pair of rails laid on the sleeper. The sleeper departure prevention guard has a predetermined interval in the longitudinal direction of the rail. It is characterized by comprising slits formed every other and a linear member inserted continuously in the longitudinal direction of the rail.

本発明は特に、平行に伸びる複数の縦梁と当該縦梁間に設置された複数の繋ぎ梁とからなるラダーマクラギに適している。すなわち、ラダーマクラギは２本の縦梁と複数の繋梁とから梯子状に構成されていて、一般に剛性が大きい。   The present invention is particularly suitable for ladder sleepers composed of a plurality of longitudinal beams extending in parallel and a plurality of connecting beams installed between the longitudinal beams. That is, the ladder sleeper is configured in a ladder shape from two vertical beams and a plurality of connecting beams, and generally has high rigidity.

そのため、鋼材などからなる逸脱防止ガードを付設すると剛性がさらに大きくなって、バラスト道床やコンクリート路盤への変位・追従がほとんど無いか非常に小さくなるため、ラダーマクラギの敷設・整正が非常に困難になる。   For this reason, if a departure prevention guard made of steel or the like is attached, the rigidity will be further increased, and there will be little or no displacement / following to the ballast roadbed or concrete roadbed, so it will be very difficult to lay and correct ladder sleepers. become.

本発明の場合、逸脱防止ガードに複数のスリットを所定間隔おきに形成して逸脱防止ガードの付設によるマクラギの剛性増大が抑えられているため、バラスト道床やコンクリート路盤への変位・追従が可能になり、ラダーマクラギの敷設・整正が非常に容易になる。   In the case of the present invention, since a plurality of slits are formed in the departure prevention guard at predetermined intervals to suppress the increase in sleeper rigidity due to the attachment of the departure prevention guard, displacement / following to the ballast roadbed or concrete roadbed is possible. It becomes very easy to lay and correct ladder sleepers.

また、逸脱防止ガードにはＰＣ鋼線やＰＣ鋼より線などのＰＣ鋼材、あるいはアラミド繊維などの新素材(ＦＲＰ)からなる連続繊維補強材からなる線状部材が連続して挿通され、各スリット間が互いに連結されていることで、互いに協同して外力に抵抗することができるため、万一脱輪して車輪がスリット間に激しく当たったとしても、車輪をレールからそれ以上逸れることのないように確実に保持することができ、スリットを有することによる強度および機能の低下もない。   In addition, a linear member made of continuous fiber reinforcing material made of PC steel material such as PC steel wire or PC steel wire, or a new material (FRP) such as aramid fiber is continuously inserted into the escape prevention guard, and each slit Because they are connected to each other, they can cooperate with each other to resist external forces, so even if you remove the wheel and hit the wheel violently between the slits, the wheel will not deviate further from the rail. Thus, the strength and function are not deteriorated due to the slits.

なお、逸脱防止ガードはマクラギの成型時にマクラギと一体に形成することも、また取付ボルト等による後付け方式によってマクラギに後から取り付けることも可能である。   The departure prevention guard can be formed integrally with the sleeper at the time of molding the sleeper, or can be attached to the sleeper later by a retrofitting method using a mounting bolt or the like.

Each member 3 is filled.

なお、各スリット２ａは、図示するように逸脱防止ガード２の上端部から中間部に渡って形成されていてもよく、あるいは逸脱防止ガード２の上端部から下端部に渡って逸脱防止ガード２を横断するように形成されていてもよい。   Each slit 2a may be formed from the upper end portion to the middle portion of the departure prevention guard 2 as shown, or the departure prevention guard 2 is extended from the upper end portion to the lower end portion of the departure prevention guard 2. You may form so that it may cross.

また、各逸脱防止ガード２には、ＰＣ鋼材４がアンボンド方式により逸脱防止ガード２の長手方向に連続して挿通され、各ＰＣ鋼材４の両端部４ａ，４ａは、例えば図２（ｂ）に図示するように逸脱防止ガード２の端部に支圧板５と定着ナット６等によってそれぞれ定着されている。また、支圧板５の裏側に合成ゴム等のクッション部材７が介在されている。   Moreover, the PC steel material 4 is continuously inserted in the longitudinal direction of the departure prevention guard 2 by the unbonding method in each departure prevention guard 2, and both ends 4a and 4a of each PC steel material 4 are shown in FIG. As shown in the figure, it is fixed to the end portion of the departure prevention guard 2 by a support plate 5 and a fixing nut 6 respectively. Further, a cushion member 7 such as a synthetic rubber is interposed on the back side of the bearing plate 5.

なお、この場合のＰＣ鋼材４の端部４ａ、支圧板５、定着ナット６およびクッション部材７はコンクリート内に埋設されている。   In this case, the end 4a of the PC steel material 4, the bearing plate 5, the fixing nut 6 and the cushion member 7 are embedded in the concrete.
