Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a rail lateral pressure reinforcement support device.

0002

[Conventional technology]

Conventional rail fastening devices for slab tracks mainly use tie plates. A fastening device is used.

0003

[Problem that the idea aims to solve]

With the recent increase in vehicle speed, rail lateral pressure has increased and conventional rail fastening systems Increase the lateral force resistance of the position. It is not easy to change or replace the tie plate structure to deal with this. In addition, the concrete slab needs to be repaired to add more anchors for fastening the rails. becomes.

0004 This invention was proposed in view of these circumstances, and its purpose is to While the structure of the conventional rail fastening device remains the same, support and reinforcement for rail lateral pressure can be achieved. The object of the present invention is to provide a rail lateral pressure reinforcement support device which has a simple structure and excellent workability.

[0005]

[Means to solve the problem]

In order to achieve the above object, the rail lateral pressure reinforcement support device according to the present invention has a strip base piece. A locking hook is formed at the distal end, and a long hole and an oblique hole at the base end are formed at an angle to the longitudinal axis of the base piece. The locking hook part of the support rod in which the concave groove is arranged is placed on the rail on the track slab plate. At the same time as locking on the side edge of the bottom of the base plate, it protrudes from the bottom surface of the seat plate having a long hole in the base end groove. The seat plate and the support are slidably fitted with protruding lines parallel to the concave grooves. The bolts passed through each long hole of the holding rod are fixed in the mortar filling holes of the track slab plate. It is constructed by screwing and tightening the built-in plug.

[0006]

[Effect]

Since the present invention is constructed as described above, the rail lateral force is applied to the bottom of the rail. It fits into the concave groove of the support rod through the support rod that is locked on the side edge through the tip locking hook. A seat plate having combined protruding ridges, a bolt passed through each elongated hole of the seat plate and the support rod. The bolts are fixed in the mortar filling holes of the track slab plate to which the bolts are screwed. The rail lateral pressure is transmitted to the track slab plate through the stopper, firmly supporting the rail lateral pressure.

[0007] In addition, the grooves and protrusions provided on the support rod and the seat plate are slid relative to each other. by adjusting the position of the support rod so that the bolt and washer are always aligned. It can be brought into contact with the rail and can reliably support the lateral pressure of the rail.

[0008]

【Example】

The present invention will be described below with reference to the illustrated embodiments. A is a support rod, which has a locking hook 2 at the tip of a band-shaped base piece 1, and a long hole at the base end. 3 and a plurality of grooves 4 obliquely intersecting the longitudinal axis of the base piece 1. B is a seat plate provided with a long hole 5 and a plurality of ridges 6 parallel to the grooves 4 of the support rod A. has been done.

[0009] Therefore, the injection pipe 8 of the mortar filling hole 7 in the track slab plate C and the filling mortar A steel pipe having a female thread 9 on the inner circumferential surface and a protrusion 10 on the outer circumferential surface. 11, or the same steel pipe 11 is placed in a synthetic resin cylinder 13 having a protrusion 12 on the outer peripheral surface. The molded embedded plug D is inserted into the perforation and fixed with adhesive with synthetic resin 14. form a linker. 15 in the figure is an upper flange piece of the synthetic resin cylinder 13.

0010 Then, the locking hook portion 2 of the support rod A is locked to the bottom side edge of the rail E, and The protruding ridges 6 of the seat plate B and the concave grooves 5 of the support rod A are fitted and slid. Therefore, the long holes 3 and 5 of the support rod A and the seat plate B should be positioned directly above the embedded plug D. After making the adjustments, insert the bolts F into each of the long holes 3 and 5 and tighten them onto the embedded plug D. Then, the support rod A is fixed to the track slab plate C. In the diagram, G is an insulating plate and H is a rail fastener. It is a knot.

[0011] Since the illustrated embodiment is constructed as described above, the lateral pressure on the rail E is It is supported by a track slab plate C via a support rod A and an embedded plug D.

0012

[Effect of the idea]

According to the present invention, as described above, the support rod is provided at the tip of the band-like base piece. Lock the locking hook part to the bottom side edge of the rail on the track slab plate, and fit it into the groove of the base piece. A protrusion provided on the lower surface of the seat plate is slidably fitted to each of the seat plate and the support rod. Pass the bolt through the long hole and insert the bolt into the mortar filling hole of the track slab plate. By screwing and tightening the fixed embedded plug, the conventional rail fastening structure remains the same. This can support the increasing rail lateral pressure.

[0013] At this time, the longitudinal direction of the base piece of the support rod provided on the support rod and the seat plate, respectively, and the The mounting position of the support rod can be adjusted by fitting the concave groove and the protrusion. It is something that can be done. Note that the embedded plug should be installed using the resin injection hole in the track slab plate. This makes construction easy and does not affect the structural strength of the track slab.
