Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad track laid across a road or a railroad crossing structure at an intersection of a ground-traveling crane track or the like and a road.

[0002]

2. Description of the Related Art Usually, a railroad crossing has a structure in which, as shown in FIG. 1, a square bar 2 having a height substantially the same as that of the rail 1 is laid between the rails 1 and on the outer side of the rail 1, and a peg 3 is driven in and fixed to a sleeper 4. In order to prevent derailment due to objects falling on rails from vehicles passing through railroad crossings such as trucks, there are many cases where wheel guard rails 5 are provided inside the rails 1 In order to protect a square bar that is easily worn by passing or re-accelerating after being temporarily stopped, a strip steel plate 6 is covered on the square bar 2.

As for the level crossing structure, Japanese Patent Publication No. 5-6
After welding the metal fittings with the locking groove and the rail fastening device to the steel sleeper in No. 3563, the prone groove steel was elastically fitted into the metal fittings, and then the pavement steel plate was put on the prone groove steel and the fastening metal fitting was used. A railroad crossing having a structure in which a metal fitting with a locking groove and a pavement steel plate are fastened is disclosed.

[0004]

In the former railroad crossing in which square bars are laid between the rails and outside the rails, the pegs for fixing the square bars loosen due to the force acting on each of the square bars when the vehicle passes,
The frequency of railroad crossing repairs increases due to the lifting of square timbers and the winding of striped steel plates, resulting in an increase in repair costs.
This obstructs the passage of trains and vehicles, and these passages pose a safety problem for repair workers.

On the other hand, the latter railroad crossing structure requires parts having a special structure or shape such as a metal fitting with a locking groove and a prone groove steel, which results in a high cost, and the prone groove steel utilizes elasticity. Since it is fitted into the metal fitting with the locking groove, special construction and tools are required. Moreover, when the track in the railroad crossing is curved or a part of the turnout is hung inside the railroad crossing, it is difficult to shape the shape of the railroad crossing plate. The present invention has been made for the purpose of solving the above problems, and provides a sturdy and durable railroad crossing structure with a small number of parts and no need for parts having a special structure, and a construction method thereof. It is what

Therefore, the railroad crossing structure of the present invention has the following features: sleepers, rails fixed on the sleepers, shaped steels arranged on the sleepers between the rails and outside the rails and fixed by fastening means, and on the shaped steels. It is characterized by comprising a steel plate fixed by a fixing means. As a fastening means for fixing the shaped steel on the sleepers,
For example, if the sleeper is made of steel, welding, if it is wooden, a set screw that is screwed into the sleeper through a stepped hole formed in the shaped steel, a presser foot that is stretched between adjacent shaped steels and presses the shaped steel. A set screw or the like for fixing the gold and the presser foot to the sleeper can be exemplified.

As a fixing means for fixing the steel plate on the shaped steel, for example, welding, a screw for connecting the shaped steel and the steel plate, a stopper such as a bolt, or the like is provided so as to project parallel to the back side of the steel plate and the shaped steel fits. A protrusion or the like can be exemplified. As the shaped steel used in the present invention, I-shaped steel having a large contact area with the sleeper and the steel plate is preferably used.

The method of constructing the railroad crossing structure described above is such that the rails are fixed on the steel sleepers, the shape steels are arranged between the rails and outside the rails and fixed by welding, and then the steel shapes are covered on the shape steels. It is made by welding to steel, and examples of the welding with the shaped steel include spot welding between the side end surface of the steel sheet and the shaped steel end surface, plug welding in which the holes are formed in the steel sheet and welded. .

Another construction method is to fix the rail on the wooden sleepers, and dispose the shaped steel between the rails and on the outside of the rails and screw the set screws into the sleepers through the stepped holes formed in the shaped steel. Alternatively, the adjacent shaped steels are fastened to each other with the holding plate and the set screw screwed into the sleeper through the holding plate, and then the shaped steel is covered with the steel plate and welded to the shaped steel. The welding with and is performed in the same manner as above.

As another construction method, in the construction method described above, instead of welding the steel plate on the shape steel, a method of connecting the steel plate and the shape steel with a fastener such as a set screw or a bolt is used. Yet another construction method is to fix the shaped steel to the back side of the steel sheet by welding, form a screw hole in the steel sheet between the shaped steels, and mount it on the sleeper via the shaped steel, and then It is characterized in that a presser foot is hung across and attached, and the presser foot is fixed to the sleeper with a set screw through a screw hole of a steel plate.

[0011]

[Function] In addition to the sleepers and rails, basically there is only need for shaped steel and steel plates, so the number of parts is small, and the shaped steel and steel plates fixed on the sleepers are both general steel materials and have a special structure. Since it is not a part, it is inexpensive and largely rigid, so it is not easily deformed by a vehicle passing over a steel plate.

Further, when the I-shaped steel is used as the shaped steel, the contact area with the sleeper is large, so that the mounting state is stable, and the shaped steel and the sleeper and the shaped steel and the steel plate are attached and detached by the fastening means and the fixing means. If it is possible, replacement and repair work can be performed easily and easily.
