合にはこれが事故の原因となることがある。2. Description of the Related Art When a train passes through a track, especially a curved part or a branch part, the rail is subjected to centrifugal force due to train passage and horizontal force due to rolling of the vehicle (referred to as lateral pressure). Is likely to cause a lateral slip on the track (longitudinal direction of the sleepers), and if left unattended, this can cause an accident in extreme cases.

る。その手段として、例えばＰＣ枕木の場合、その敷設
面にゴム板を現場で貼付けてバラスト道床との摩擦抵抗
を大きくし、枕木の横ずれを少なくすることが行われて
いた。In order to prevent the movement of the sleepers due to such lateral pressure, it is necessary to increase the roadbed lateral resistance force. As a means for this, for example, in the case of a PC sleeper, a rubber plate is attached on the laying surface at the site to increase the frictional resistance with the ballast ballast and reduce the lateral slippage of the sleeper.

ったり、充分な接着強度が得られないことがあった。ま
た、貼付けたゴムが剥がれやすいという問題もあった。However, since the work of sticking the rubber plate on the site is performed only at night when trains are far from passing, the sticking surface of the sleeper cannot be stuck because it is wet with night dew, etc. In some cases, strength could not be obtained. There is also a problem that the applied rubber is easily peeled off.

なければならなかった。On the other hand, the sleepers made of wood or synthetic wood are laid on the ballast ballast as they are without attaching a rubber plate, so that the sleepers are likely to slip laterally, and maintenance work for correcting the slippage is required. I had to do it often.

In the sleeper described in -68158, for example, as shown in FIG. 3, the sleeper main body S 1 is attached with a convex member a such as a square pole with an adhesive. As shown in FIG. 4, the sleeper main body S 2 is U-shaped. The channel material b is fixed with bolts and nuts c, or as shown in FIG. 5, the convex portion d is formed by a method such as cutting a groove in the main body S 3 of the sleeper.

る。However, the sleepers described in Japanese Utility Model Application No. 4-68158 also have the following problems. In other words, a sleeper body having a convex portion formed by cutting is considerably difficult to perform at a track laying site where cutting equipment is scarce. Therefore, it is necessary to carry in what has been processed in a factory equipped with cutting equipment in advance. Further, in the case where a convex member is attached to the main body of the sleeper or fixed by mechanical means to form the convex portion, a considerable amount of labor and time are required for the attaching or fixing work. Furthermore, since the sleepers are uneven, storage and transportation may be difficult.

凸部を形成するのが容易であることが望まれる。Also, in the case of a sleeper in which a convex portion is formed on the side surface of the sleeper main body, since the ballast usually has a small covering thickness,
When lateral pressure is applied, the ballast escapes upward, and the rate of increase in road lateral resistance decreases. On the other hand, in the case of the sleeper in which the convex portion is formed on the laying surface of the sleeper main body, the ballast is often covered, so that the ballast is unlikely to escape upward, which increases the rate of increase in lateral bed resistance. Therefore, it is extremely preferable that the convex portion for increasing the lateral lateral resistance is formed on the laying surface of the sleeper. From such a point, it is desirable that the convex portion is easily formed on the laying surface of the sleeper. Be done.

The locking plate bites into the ballast and acts to lock the lateral shift of the sleeper against the roadbed, but since the locking plate is projected on the laying surface of the sleeper, the ballast has a large covering thickness and it is difficult for the ballast to escape upward. . As a result, the roadbed lateral resistance is increased and the sleepers are less likely to slip sideways.

FIG. 1 is a perspective view showing a usage mode of a buckling prevention plate of an embodiment of the present invention, and FIG. 2 is a sectional view showing a usage mode of a sleeper to which the buckling prevention plate shown in FIG. 1 is attached. As shown in FIG. 1, the buckling prevention plate 1 has a fitting portion 2 in which a steel plate having the same width as that of the sleeper 4 is bent and formed into a substantially U shape like an upper plate 21, a side plate 22, and a bottom plate 23. The bottom plate 22 is further bent, and the buckling prevention plate 1 is formed of the locking plate 3 protruding from the laying surface 41 side of the sleeper 4 in a state of being fitted to the end portion 42 of the sleeper 4. The upper plate 21 is provided with bolt holes 211 for fixing the buckling prevention plate 1 to the sleeper 4.

Was set to B = 240 mm like the width of the sleeper 4. Lock plate 3
It is preferable that the height H is 1/2 or more of the particle diameter of the ballast, and in this embodiment, H = 40 mm. Further, by increasing the distance L from the outer surface of the side plate 22 to the outer surface of the locking plate 3, the ballast of the shoulder of the roadbed is reduced to the sleeper 4.
Has the effect of restraining the movement of the road and slightly increasing the lateral roadbed resistance. The value of L is usually the particle size of the ballast (usually 40-6
2 mm or more, preferably 150 to 200 mm. If it is less than 150 mm, the rate of increase in lateral roadbed resistance is small, and if it exceeds 200 mm, it is almost the same as the rate of increase in lateral roadbed resistance when it is 150 mm. In addition, the retracted dimension from the end face 42 is large, and the workability of attaching to the sleeper 4 is good. Is bad. In this example, L = 200 mm.

The buckling prevention plate 1 can be pushed in so that the inner surface of the side plate 22 comes into contact with the end surface 42 of the sleeper 4, and can be easily fitted,
It was possible to project the locking plate 3 on the laying surface 41 of the sleeper 4. Further, in order to ensure reliability, the buckling prevention plate 1 was fixed to the sleeper 4 with bolts using the bolt holes 211.

じ、木ねじ等によって固着することがより好ましい。If the buckling prevention plate 1 is not fixed to the sleeper 4, the buckling prevention plate 1 needs to be attached to at least the end of the sleeper 4 on the side where the lateral pressure is applied. However, in order to reduce the centrifugal force at the curved and bifurcated parts of the track, when the train is slowing down, the train is slower than the centrifugal force. It is preferable to attach the buckling prevention plate 1 to both ends of the sleeper 4 because component force in the direction acts and force in both directions may act due to rolling of the train. Furthermore, bolts, tapping screws, wood screws, etc. It is more preferable to adhere by.

込みやすく、敷設が楽であった。Next, the sleeper 4 with the buckling prevention plate 1 attached in this way was laid on the ballast bed as shown in FIG. 2. The locking plate 3 was as shown in FIGS. Since it is thinner than the conventional convex parts of the sleepers, it is easy to bite into the ballast and is easy to lay.

The ballast on the shoulder of the track has a greater effect of restraining the movement of the sleeper 4. As a result, the roadbed lateral resistance is 1

It increased significantly to 0 kgf.
