Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad crossing structure that can be installed and repaired easily and easily without the need for broken lines in the track.

[0002]

2. Description of the Related Art A conventional railway crossing structure that utilizes the internal elastic deformation of a railroad crossing structure that can be easily and easily implemented without the need for broken lines in railroad tracks is disclosed in, for example, Japanese Patent Publication No. 60-24244. Insert the road surface plate made of elastic rubber material between the rails of the railroad crossing while elastically deforming it, and close the edge of the plate between the side upper neck part and the lower neck part of the rail abdomen as the deformation recovers after insertion. The vertical movement of the plate body with respect to the rail is controlled by pushing and engaging the plate with the rail.

[0003]

According to the above structure, since the edge of the plate is pressed closely against the side of the abdomen of the rail, rainwater is drained from the engaging portion of the rail and the plate. Difficult to flow into the edge road on the top edge of the plate,
Then it is drained along the rail.

Further, since the abdomen of the rail and the edge of the plate body are in close contact with each other, there is no air permeability at the rail bottom portion in the plate laying range.
It gets damp.

For this reason, there is also a problem that rust is likely to occur on the fastener.

[0006] Therefore, an object of the present invention is to provide a railroad crossing structure in which water is drained to the lower side of the pavement and the fasteners do not become damp.

[0007]

In order to solve the above-mentioned problems, the present invention elastically deforms and fits between rails in a railroad crossing execution area, and when the deformation returns after the fitting, an edge is formed on the abdominal surface of the rail. Side-by-side elastically deformable pave plates that are close to each other so that they do not touch each other, through holes provided along the rails at the edge parts of the pave plate, and through holes arranged in series. A strong pipe inserted over the entire length of the pavement, a pair of contact plates placed on the outside of the pavement on both sides, a fastener that draws these contact plates, and moves in all directions to the outer edges of the pavement on both sides. It is configured with a stopper fitting that is engaged so as not to be fixed to the sleeper or the base plate.

[0008]

[Operation] After elastically deforming the rails to fit the pavements in parallel, insert one pipe into the entire length of the through holes arranged in series, and then apply the pipes to the outside of the pavements on both sides. While arranging the boards, the pavement boards that are juxtaposed in parallel are integrated while pulling the two contact plates together with the fasteners.

Further, after engaging the stoppers with the pavement on both sides integrated, the stoppers are fixed to the sleepers and the foundation plate to prevent the pavement from rising and running, and to prevent the rail abdomen from rising. A predetermined gap for drainage or ventilation is provided between the side surface and an edge portion fitted between the upper neck portion and the lower neck portion of the rail abdomen.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, an elastically deformable pavement plate 1 is elastically deformed and fitted between the rails A and A in the railroad crossing execution area. The retaining edge 2 on the edge of the pavement 1 does not come into contact between the upper neck portion a ′ of the side of the abdomen a and the lower neck portion a ″ (with respect to the side surface of the abdomen a of the rail A and the upper neck portion a ′). Bring them close together.

The pavement boards 1 are fitted in order and are arranged in parallel in a required number.

The pavement plate 1 has an inside track and an outside track,
In the case of the track, the edges 2 are provided at both ends of the pavement 1, and between the tracks, the edge 2 is provided at both ends of the pavement 1, and the edge 2 is provided only at one end of the pavement 1, As shown in FIG. 1, the edges of the pavement plate 1 without the edge portion 2 are opposed to each other at a predetermined interval, and then the asphalt 3 is filled between the opposed ends of the pavement plates 1 and 1, and In the case of the outside, there is a case where the edge portion 2 is provided only on one end of the pavement plate 1 and the road surface asphalt 4 is filled between the edge without the edge portion 2 and the road.

In the illustrated case, the pavement plate 1 is composed of hollow steel pipe aggregates 5 arranged to withstand a predetermined load, and the aggregates 5.
And a rubber coating 6 integrally provided with the edge portion 2 so as to be buried therein, and is formed in a rectangular plate shape in the illustrated case.

Further, a through hole 7 extending along the rail A is formed in the edge portion 2.
In addition, through the through holes 7 arranged in series, a tough pipe 8 made of a hard synthetic resin, a steel pipe or the like (one or a plurality of pipes with their edges abutted) is penetrated, and then both sides are The outer peripheral surface of the pavement board 1 and the end surface of the pipe 8 are circumscribed by the back surface of the peripheral edge portion of the contact plate 9, and then the contact plates 9 are fastened by the fastener 10.
By pulling together and integrating them, it is possible to prevent the pavements 1 arranged in parallel from partially rising.

The fastener 10 is composed of a shaft member to be inserted into the pipe 8 and a nut screwed into the threaded portions at both ends of the shaft member.

When the ends of the pipes 8 project on the outer surfaces of the pavement 1 on both sides, the contact plates 9 are abutted only on the edges of the pipes 8, and the outer surface of the pavement 1 on both sides is in front. When the end of the pipe 8 is located at, the contact plate 9 is brought into contact with only the pavement plate 1.

Further, the outer edges of the pavement 1 located on both sides are engaged with stoppers 12 which are fixed to the sleepers 11 or the concrete base plate to stop the movement (lifting or running) in all directions. It is like this.

As a result, a constant gap is always maintained between the abdomen a and the upper neck a'of the rail A and the edge 2, and rainwater on the pavement 1 passes through the upper neck a'of the rail A to the abdomen. The notch 13 provided so that the fastening metal fitting B of the rail A fits in from the lower end edge portion of the pavement plate 1 toward the front end surface of the edge portion 2 of the pavement 1.
It flows into and is drained, and it is also breathable.

The above-mentioned stopper 12 is shown in FIGS. 2, 3 and 4.
As shown in FIG. 2, a seat plate 15 for fixing the bolts 14 to the sleeper 11, a vertical plate 16 standing upright from the seat plate 15, and a horizontal plate 1 which is continuous from the upper end of the vertical plate 16 and projects to one side.
The horizontal plate 17 does not interfere with walking in the recessed stepped portion 18 formed by opening the outer edge upper surface and side surface of the side pavement plate 1, and the front edge and both sides of the horizontal plate 17 The edge is brought into contact with the peripheral edge of the recessed stepped portion 18 and fitted.

The elastic deformation caused by the fitting of the pavement plate 1 deforms only the edge portion 2 by the through hole 7 which accelerates the elastic deformation when the aggregate 5 is buried.

Reference numeral 19 in the drawing denotes a ridge provided on one of the butted edges of the pavements 1 arranged in parallel, and the ridge 19 is fitted into the groove portion 20 of the other.

[0023]

As described above, according to the railroad crossing structure according to the present invention, a certain gap is provided between the edge of the paving plate laid in parallel with the rail abdomen and the rail upper neck and abdomen. Therefore, the water can be drained, and since it has air permeability, it is possible to suppress the generation of rust on the fastening fitting due to steaming.

[0024] Furthermore, since the metal fittings are engaged with the outer edges of the pavement on both sides so as not to move in all directions, and the metal fittings are fixed to the sleepers and the foundation plate, the pavement is prevented from rising and moving forward. Stops, drainage and ventilation gaps can be kept constant.

Further, since the pipes are inserted into the through holes arranged in series and the contact plates arranged on the side surfaces of the pavement plates on both sides are pulled by the fasteners, the pavement plates arranged in parallel are integrated and the top faces are the same. The level does not occur and there is no step.
