Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a rail joint structure, and relates to a rail joint structure which is less likely to cause vibrations and noises and is easy and inexpensive to replace the rail.

[0002]

[Prior art]

 Conventionally, a seam structure of this type of rail has been shown in FIG. A and B are conventional vertical rails, which have a structure in which end portions A'and B ', which are cut at an angle orthogonal to the longitudinal direction of the vertical rails A and B, are connected by bolts while facing each other. . D is a sleeper, and E is a bolt for fixing the rails A and B to the sleeper D. Since the conventional rail joint structure is configured as described above, a gap C is formed at the connecting portion of the vertical rails A and B, so that a train or the like passes through the gap C each time. There was a problem that the train became uncomfortable to use due to vibrations and noise, and that noise pollution was developed in the neighborhood.

Further, in order to solve the problems such as vibration and noise, there is a structure in which an embedding member is inserted into the gap C to reduce the vibration, but it is not sufficient. Furthermore, in order to solve such problems, there is a trend toward longer rails with fewer connecting parts between rails.However, even with this long rail, the connecting structure of the connecting end uses the structure of the conventional connecting part. Therefore, it was not possible to solve the above problems sufficiently.

[0004]

[Problems to be solved by the device]

 Since the conventional rail joint structure is configured as described above, the rail connection part, that is, the end part of the rail, has a higher degree of progress of wear deterioration than other long rail parts. is there. As a result of wear of the rail connecting portion, there is a problem that the entire rail must be replaced although it can be used as a whole rail. As a result, there is a problem that the work time and the work period are long or long, the number of workers for the work is considerable, and the replacement cost of the rail is accordingly high.

The present invention aims to reduce the vibration and noise generated when a train passes through a rail connecting portion, and at the same time, it is easy to replace the rail when the rail connecting portion is worn out. It is intended to provide a rail joint structure that can be manufactured at low cost.

[0006]

[Means for Solving the Problems]

 The present invention is intended to solve the above problems and is configured as follows. A first invention intended to receive registration is to lay opposite vertical rails having vertical end surfaces cut at an angle orthogonal to the longitudinal direction of the rail at predetermined intervals, and to have the vertical end surfaces facing each other. While connecting the vertical rails with the connecting rails facing each other, the vertical rail side end faces of the connecting rails are formed on the vertical end faces cut at an angle orthogonal to the longitudinal direction of the rails, respectively, and the connecting rails of the facing connecting rails are connected to each other. Each end face is cut vertically at an angle inclined to the longitudinal direction of the rail, and the cut inclined end faces are laid between the vertical rails so that they face each other. It is configured by a connecting plate in which both abdominal portions of the end portion and the opposing connection rail having the inclined end surface portion are integrally connected.

With the above-described configuration, it is possible to reduce vibrations, noises, and the like that occur when the train passes through the rail connecting portion. In addition, even if the rail connecting part wears due to aging, it is not necessary to replace the entire rail, and only the connecting part rail needs to be replaced. The work is simple and can be done in a short time, and at a low cost.

The second invention for receiving registration is the same as the first invention, in which the end surfaces of the vertical end surfaces of the opposing vertical rails and the end surfaces of the connecting rails facing the vertical rail are fitted to each other. A dowel hole is provided and both mating holes are connected by mating pins. By configuring as above, the vertical rails facing each other and the connecting rails facing each other are integrally fixed, and since there is no gap in the connecting portion between both rails, the service life for a pair of vertical rails increases. It will be done.

The vertical rails 1 and 2 are spaced at predetermined intervals. Has been laid down. The vertical rails 1 and 2 facing each other are laid at an interval of about 1 m. Since the vertical rails 1 and 2 are paired with the opposing vertical rails 1'and 2'on the other side, only one of the vertical rails 1 and 2 will be described below, and the other side will be described. The description of the vertical rails 1'and 2'is omitted. The same applies to the connection rails described below.

Reference numerals 3 and 4 denote connection rails laid between the opposed vertical rails 1 and 2, which are connected together with the vertical rails 1 and 2 so as to form one rail as a whole. . The connecting rails 3 and 4 have the same rail track surfaces 3c and 4c as the width of the vertical rails 1 and 2 described above, but the legs 3d and 4d have a width of the track surface to reinforce the strength. It is connected to the flat bottom portions 3e and 4e as it is, and is integrally configured.

Further, the connection rails 3 and 4 are formed into vertical end face portions 3a and 4a obtained by cutting the end faces on the side of the vertical rails 1 and 2 respectively at an angle orthogonal to the longitudinal direction of the rail, and the connection rails facing each other are also formed. Each of the rails 3 and 4 is formed with slanted end face portions 3b and 4b, which are obtained by vertically cutting the end faces of the rails 3 and 4 at an angle inclined to the longitudinal direction of the rail. If the cutting angle of the inclined end face portions 3b and 4b is about 15 degrees, vibration and noise can be reduced even if a train or the like passes through this connecting portion.

[0013] Furthermore, fitting holes are respectively formed in the connection end surfaces of the vertical end surfaces 3a and 4a with the end surfaces of the vertical end surface portions 1a and 2a of the opposed vertical rails 1 and 2 and the vertical rail side end surfaces of the connection rails 3 and 4, respectively. 5, 6 and 7, 8 are provided and both fitting holes 5, 6 and 7, 8 are connected by fitting pins 9 and 10. In the illustrated embodiment, the fitting holes 5, 6 and 7, 8 are provided at two places respectively, and the fitting pins 9 and 10 are also provided at two places respectively, but the vertical rails 1 and 2 and the connection rail 3 are also provided. It is for connecting with 4 and 4 without forming a gap, and the number thereof is not limited and the shape thereof is not limited, as a matter of course.

Although not shown, a spring member is inserted into one of the fitting holes, and its end is brought into contact with the fitting pin so that the vertical rail and the connection rail are connected and fixed. By doing so, the work of laying and fixing the rails becomes easier.

Reference numeral 11 denotes a connecting plate, which is for laying the vertical rails 1 and 2 and the connecting rails 3 and 4 and then fixing these rails so as to be integrated from both sides. The leg portions 1d and 2d of the vertical rails 1 and 2 are formed to have the leg width of a normal rail. That is, the width is formed narrower than the width of the rail track surfaces 1c and 2c of the vertical rail. On the other hand, the leg portions 3d and 4d of the connection rails 3 and 4 are formed to have the same width as the rail track surfaces 3c and 4c and are connected to the flat bottom portions 3e and 4e. Therefore, the plan view shape of the connection plate 11 that integrally fixes these is formed in an angle shape so as to straddle both the connection rails 3 and 4.

Further, the connection plate 11 is formed with connecting holes for sandwiching and fixing these rails, and a connecting hole 11a for fixing the vertical rail and a connecting hole 11b for fixing the connecting rail are formed. Each is formed. The vertical rail leg and the connecting rail leg are also provided with connecting holes 3f and 4f at positions corresponding to the connecting holes 11a and 11b of the connecting plate 11, and these connecting holes 11a, 11b and 3f, It is formed so as to be fixed by the bolt 12 so as to penetrate 4f.

The connection rail fixing connection hole 11b is formed in a long hole that is laterally long with respect to the longitudinal direction of the rail, so that the width extension phenomenon of the vertical rails 1 and 2 can be dealt with. Fine adjustment is easy during laying work. In the figure, 13 is a sleeper, and 14 is a bolt for fixing each rail 1, 2, 3, 4 to the sleeper 13.
