Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for fastening a turnout that constitutes a railway track onto a PC sleeper.

(Prior art and its problems) A turnout is a device that branches a train in the intended direction using a structure that combines rail materials.
As shown in the figure, a point part 10, a lead part 20
It is divided into the crossing guard part 30, and the point part 10 has a basic rail SR and a tongue rail.
In combination with TR, the lead part 20 is connected to the main rail.
Combining MR and lead rail LR, and combining main rail MR, guard rail GR and crossing FR in the crossing guard part 30,
Attach each rail material to the floorboard with washer bolts, etc.
Currently, the floorboards are attached to wooden sleepers using dog nails or screw nails. However, wooden sleepers corrode and decay over time, so they need to be replaced regularly. In addition, they are lightweight and unstable, and because they are fastened with dog nails or screw nails, the fastening force is unstable, making it difficult to connect branch rails. It has the disadvantage that it is easy to cause track damage as well as track deviation and acceleration.

(Purpose of the invention) In view of the above-mentioned conventional drawbacks, the purpose of the present invention is to provide a structure for elastically fastening rails to the PC sleepers while simultaneously converting the sleepers into PC sleepers when connecting turnouts. .

(Structure of the idea) In order to use PC sleepers for turnouts, it is necessary to devise a mechanism for fastening each rail to the PC sleepers. Therefore, in this invention, point part 1
0. When arranging the turnout including the lead part 20 and the crossing guard part 30 on the PC sleeper, "At the point part 10, on the point part PC sleeper 11, there are a pair of left and right concave floor plate receivers 11a, 11a.
The floor plate 12 that absorbs the intersecting angle of the rails and changes in the rail position and fastens the rails is attached to the floor plate receiving portion 1.
1a, and both ends of the floor plate 12 are connected to the leaf springs 1.
6 and 16, and in the lead part 20, each rail is provided on the lead part PC sleeper 21, and a concave receiving part 21a having an arcuate part 21b at both ends is provided, and it is placed on each receiving part 21a. The lower ends of each rail are elastically fastened along the arcuate portion 21b by a spring holder 24 whose arrangement angle with respect to the rail can be adjusted by following the crossing angle of the plate springs 22, 22 with respect to the rail. In the guard part 30, concave floor plate receivers 31a are provided on the PC sleepers 31 at three locations on the left, right and center, and the floor plates 32 to which the rails are fastened are connected to each floor plate receiver 31a to absorb the intersecting angle of the rails and changes in the rail position. . . , and both ends of the floor plate 32 are elastically fastened using leaf springs 33, 33.

Hereinafter, the present invention will be explained in detail based on specific examples shown in the accompanying drawings.

(Example) FIGS. 2, 3, and 4 show a plan view of the point portion 10, an enlarged view of its essential parts, and a sectional side view thereof. 11a, 11a are provided, and fastening bolt embedded plugs 11b are embedded and fixed in both ends of the receiving portion 11a. On the other hand, on the floor plate 12 are the basic rail SR and the tongue rail TR.
The rails are fastened by absorbing changes in the rail intersection angle and rail position, and are connected to the floor plate 1 via the track pad 13.
2 is placed in the floor plate receiving portion 11a. The floorboard 1
2 is elastically fastened by pressing the end portions of double leaf springs 16, 16 with their spring butts resting on a spring holder 14 by the fastening force of a fastening bolt 15.

Next, FIGS. 5, 6, and 7 show a plan view, an enlarged view of the main parts, and a cross-sectional side view of the lead part 20, and show a pair of left and right main rails MR on the lead part PC sleeper 21, and a central part. A concave receiving portion 21a for receiving each rail of a pair of lead rails LR...
... and embedded plugs 2 for fastening bolts on both sides.
1c, 21c are embedded, and an arcuate receiving part 2 is formed with steps on both sides located on the outside thereof.
1b is provided. Each of the rails MR and LR is placed on each of the receiving portions 21a via the track pads 23, and both lower ends of each rail are connected to the arcuate receiving portions 21a.
Insert a spring holder 24 having an arcuate portion with the same radius on the back side along b, place the spring butt on the holder 24, and adjust the angle at which the tip is arranged with respect to the rail.
Tighten the bolt 1 at the tips of the double plate springs 22, 22.
It is pressed with a tightening force of 5 and is elastically fastened. However, 25 is a gauge block.

Finally, Figures 8 and 9 show the crossing
A plan view of the guard part 30 and an enlarged cross-sectional side view of the main parts thereof are shown. Concave floor plate receivers 31a are provided at three locations on the PC sleeper 31, on the left, right and center, and fastening bolts are provided at both ends of the receivers 31a. Embedded plug 3
Embed and fix 1b. On the other hand, the main rail MR, guard rail GR, and crossing CR are connected to the floor plate 32 by absorbing the intersecting angle of the rails and changes in the rail position, and the floor plate 32 is placed in the floor plate receiving portion 31a via the track pad 33. place Both ends of the floor plate 32 are pressed by the fastening force of a fastening bolt 36 with the tips of double leaf springs 33, 33 whose spring ends are placed on a spring holder 24, and are elastically fastened.

(Operations and Effects of the Invention) As is clear from the above description, according to the present invention, when a turnout including the point part 10, the lead part 20, and the crossing guard part 30 is disposed on the PC sleeper, the point part 10 In this case, a pair of left and right floor plate receivers is provided on the PC sleepers, and the floor plates are elastically fastened using leaf springs, and the rails are fastened in the receivers by absorbing changes in the intersecting angle and position. To receive each rail, a concave receiving part having an arcuate receiving part at both ends and a rail receiving part in the center is provided, and both lower ends of each rail placed on each receiving part are attached to the rail along the arcuate receiving part. The intersecting angle of the leaf spring with respect to the rail is followed and elastically fastened via a spring holder whose arrangement angle can be adjusted, and in the crossing guard section 30, concave floor plate holders are provided at three locations on the left, right and center on the PC sleeper. , the cross angle of the rails and changes in rail position are absorbed, and the rails are elastically fastened using leaf springs via the floorboards, so sleepers at turnouts are
PC sleepers can be used, and unlike traditional wooden sleepers, the sleepers do not corrode or decay, improving durability, and the sleepers are heavy and stable.
As a result of making it difficult for track destruction to proceed, maintenance can be reduced. In addition, since the rail can be elastically fastened to the PC sleeper at the same time, the fastening force is more stable compared to the conventional fastening of floorboards with dog nails or screw nails, and there is no need to worry about track deviations of the turnout rail. This has the advantage that it is possible to prevent the vehicle from moving forward, reduce damage to turnout members, and reduce track damage due to the buffering effect against the wheel load and lateral pressure.
