ればならない欠点がある。 As a device for elastically fastening the rail to the concrete sleeper, spring nails are installed in the concrete sleeper using wedge materials, and the longitudinal direction is perpendicular to the longitudinal center line of the rail. There is a method in which the rail is inserted into a spring nail and the rail is fastened with the spring nail.
In the conventional method, a spring nail bent in the same direction as the longitudinal direction of the insertion hole is used, so the spring nail sometimes falls into the insertion hole during operation, and it takes time to take it out. This is becoming an impediment to prompt enforcement. Furthermore, since the rails and the concrete sleepers are not electrically insulated, although it can be used for side lines and factory lines, it cannot be used for main lines due to the relationship with signal track currents. Furthermore, when lateral pressure from the wheels is applied to the rail, the spring nails are not designed to receive this elastically, so the lateral pressure from the wheels is directly applied to the single concrete sleeper. Concrete sleepers have the disadvantage of having to be designed to withstand large loads, as they are subjected to concentrated loads.

3 is a concrete sleeper, and 3 is an insertion hole provided in the concrete sleeper. A spring nail 5 and a wedge member 6, which will be described later, are inserted into the insertion hole 3. The insertion hole 3 is formed so that its longitudinal direction is perpendicular to the longitudinal centerline of the rail 1, and its width is somewhat wider than the widths of the spring nail 5 and the wedge material 6. The rail-side surface of the insertion hole 3 descends almost vertically, and the lower part thereof forms a recessed inclined surface 31 inclined toward the rail. The back surface 32 facing the rail side surface is formed into an inwardly inclined surface that is compatible with the back surface of a wedge member 6, which will be described later. 4 is a track part laid between the rail 1 and the concrete sleeper 2, and 5 is a spring nail. The spring nail 5 is made of elastic steel bar,
The upper part 51 is bent at right angles to the left and right with respect to the longitudinal direction of the insertion hole 3. The length of the bent portion 51 is set to be larger than the width of the insertion hole 3. The tip of the upper part 51 and the upper shaft part 54 of the spring nail 5 are in contact with the bottom upper surface and the bottom side surface of the rail 1 via the electrical insulating material 7, and the center part 52 is slightly bent in the direction of the wedge member 6. In contact with the wedge member 6, the lower portion 53 is bent upward in the rail direction and in contact with the recessed inclined surface 31.

る。 The electrical insulating material 7 has a cross-sectional shape, and is set wide enough to allow the upper bent portion 51 of the spring nail 5 to be placed on its surface. The wedge member 6 is made of steel, and its width W is the same as the width of the spring nail 5. The front surface 62 of the wedge member 6 is substantially vertical, and the back surface thereof is formed into an inclined surface with a wedge angle, and is compatible with the back surface 32 of the insertion hole 3. A notch 61 is formed in the upper rear surface of the wedge material 6, so that the wedge material 6 can be easily pulled out.

れ、その結果レ−ル１は弾性締結される。 In order to fasten the rail 1 to the concrete sleeper 2 using the rail elastic fastening device according to the present invention, the concrete sleeper 2 with insertion holes 3 formed in advance is laid, and the rail 1 is inserted into the concrete sleeper 2. A track part 4 is installed on the upper surface of the concrete sleeper part located between holes 3 and 3.
and place rail 1 on top of it. Thereafter, an electrical insulating material 7 is installed over the upper surface of the rail bottom adjacent to the insertion hole 3 and the side surface of the rail bottom. The spring nail 5 is inserted into the insertion hole 3, and the upper part 51 is in close contact with the upper surface of the electrical insulating material 7, the upper part 54 of the shaft part is in close contact with the side surface, and the tip of the lower part 53 is in contact with the concave inclined surface 31.
Place it so that it is in contact with. In this state, the wedge material 6 is inserted between the spring nail 5 and the back surface 32 of the insertion hole 3, with the back surface of the wedge material 6 in contact with the back surface 32 of the insertion hole 3, and the spring is inserted into the front surface of the wedge material 6. The center portions 52 of the nails 5 should be in contact with each other. When the head of the wedge member 6 is lightly pushed downward using a hammer or the like, the wedge member 6 advances downward while pushing the bent central portion 52 of the spring member 5. At this time, the force that pulls down the spring nail 5 is exerted by the frictional force generated between the wedge material 6 and the spring nail 5, and the spring nail 5 has its upper part 51, center part 52, and lower part 53. While being elastically deformed, they are pushed down little by little in the direction of the rail, and as a result, the rail 1 is elastically fastened.
楔材６の楔角度は十分小さい角度に設定されて
いるので、打ち込まれた楔材６は浮き上ることな

弾性締結することができるとともに、ばね釘５の
下部５３は挿入孔３の下部の凹み３１の中に入り

ね釘５が弛緩する恐れもない。 Since the wedge angle of the wedge material 6 is set to a sufficiently small angle, the driven wedge material 6 does not lift up, and the rail 1 can be elastically fastened from the top, bottom, left and right using the spring nails 5. At the same time, since the lower part 53 of the spring nail 5 is inserted into the recess 31 at the lower part of the insertion hole 3, there is no fear that the spring nail 5 will loosen unless the wedge material 6 is pulled out.

く、その近傍の数本のまくらぎで分担されるの
で、１本のまくらぎに集中する従来方式と比し、
かなり細いまくらぎで、それに耐えることがで
き、経済的に有利である。 When the wheels of the train move left and right and a lateral force is applied to the rail 1, the rail 1 is moved by the upper part 5 of the spring nail 5.
4 is pushed in the lateral direction, but the upper part 54 of the spring nail 5 is provided with a certain amount of elastic deformation to allow for horizontal movement, so the lateral force applied to the rail 1 is reduced. The energy is not concentrated on one sleeper, but is shared among several sleepers in the vicinity, so compared to the conventional method where the energy is concentrated on one sleeper,
It is a fairly thin sleeper that can withstand it and is economically advantageous.

The cables are electrically isolated. Therefore, even if the present invention is applied to a general railway where train control information is obtained through track current, reliable reception and reception of train control information is guaranteed, and the invention can be effectively used.
レ−ル１とコンクリ−トまくらぎ２との締結を
解くには楔材６の切欠き６１を利用して楔材６を
引き抜いた後、ばね釘５を抜けば良い。 To release the fastening between the rail 1 and the concrete sleeper 2, the wedge member 6 is pulled out using the notch 61 of the wedge member 6, and then the spring nail 5 is pulled out.

The spring nail 5
Even if the spring nail 5 is displaced during operation, the bent portion will not catch on the insertion hole 3 and the spring nail 5 will not fall into the insertion hole 3, so that construction can be carried out reliably.
