Description

[0001]
[Industrial applications]
The present invention relates to a method of constructing a level crossing structure at an intersection of a road with a railway track laid across a road, a ground-traveling crane track, or the like.
[0002]
[Prior art]
As shown in FIG. 1, a railroad crossing usually has a structure in which square members 2 having almost the same height as the rails 1 are laid between the rails 1 and outside the rails 1, and the pegs 3 are driven in and fixed to the sleepers 4. In order to prevent derailment due to an object falling on a rail from a vehicle passing through a railroad crossing such as a truck, in many cases, a guard wheel rail 5 is provided inside the rail 1, and in recent years, passing of a large vehicle or once In order to protect a square material that is easily worn by re-acceleration after stopping, a striped steel plate 6 is also put on the square material 2.
[0003]
In addition to the railroad crossing structure, in Japanese Patent Publication No. Hei 5-63563, a fitting with a locking groove and a rail fastening device are welded to a steel sleeper, and then a prone groove steel is elastically fitted into the grooved metal fitting, and then the paved steel sheet is prone. A railroad crossing having a structure in which a metal fitting with a locking groove and a pavement steel plate are fastened to a grooved steel by a fastening metal fitting with a fastening metal fitting is disclosed.
[0004]
[Problems to be solved by the invention]
In the former railroad crossing, in which square bars are laid between the rails and outside the rails, the pegs that fix the square bars loosen due to the force acting on each square bar when passing through the vehicle, the square bars are lifted up, or the striped steel plates are rolled up. The frequency of repairs has increased, and as a result, repair costs have increased, the traffic of trains, vehicles, etc. has been hindered, and there has been a problem with the safety of repair workers due to these traffics.
[0005]
On the other hand, the latter railroad crossing structure requires special structure or shape parts such as metal fittings with locking grooves, prone grooved steel, and the like, which increases the cost. Special fittings and tools are required to fit the fittings with stop grooves. In addition, when the track inside the railroad crossing is curved or when a part of the branching device 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-described problems, and has an object to provide a solid and durable construction method of a railroad crossing structure which requires a small number of parts and does not require specially structured parts. Things.
[0006]
The present invention therefore comprises a sleeper, a rail fixed on the sleeper, a section steel arranged between the rails and on the outer side of the rail, fixed by fastening means, and fixed on the section steel by fixing means. In the construction method of the railroad crossing structure consisting of steel plate, while fixing the shape steel on the back side of the steel plate by welding, forming a screw hole in the steel plate between the shape steel, mounting it on the sleeper via the shape steel, Next, a presser foot is attached between adjacent steel bars and attached, and the presser foot is fixed to the sleeper with a set screw through a screw hole of the steel plate .
As a fastening means for fixing the shaped steel on the sleeper, for example, when the sleeper is made of steel, welding, when it is made of wood, a set screw screwed into the sleeper through a stepped hole formed in the shaped steel, A presser foot that is hung between shaped steel bars to be pressed and that presses the shaped steel and a set screw that fixes the presser foot to the sleeper can be exemplified.
[0007]
As the fixing means for fixing the steel sheet on the shaped steel, for example, welding, screws for connecting the shaped steel to the steel sheet, fasteners such as bolts, projections projecting parallel to the back side of the steel sheet and fitting the shaped steel, etc. Examples can be given. As the shaped steel used in the present invention, preferably, an I-shaped steel having a large contact area with a sleeper and a steel plate is used.
[0008]
[Action]
In addition to the sleepers and rails, there is basically only a 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, not specially structured parts. Therefore, it is inexpensive, has high rigidity, and is hardly deformed by a vehicle passing over a steel plate.
[0009]
In addition, if I-shaped steel is used as the shaped steel, the contact area with the sleeper is large, so that the mounting condition is stable, and the shaped steel and the sleeper and the shaped steel and the steel plate can be attached and detached by fastening means and fixing means. In this case, replacement and repair work can be performed easily and easily.
[0010]
【Example】
Wooden sleepers 12 are laid at regular intervals on the baluns 11, and rails 13 are arranged side by side on the ties 12 at right angles. Between the rails 13, an I-shaped steel 14 is fixed to the back surface by welding and arranged side by side, and a striped steel plate 15 having a width slightly smaller than the distance between the rails is arranged at a certain interval from the rail 13, and the presser foot 16 is moved. After spanning and attaching between the adjacent I-beams 14, the screw spike 18 is screwed by a wrench through a screw hole 17 formed in the striped steel plate 15 between the I-beams, and the presser foot 16 is fixed to the sleeper 12. On both outer sides of the rail 13, a pair of I-shaped steels 14 are similarly fixed on the back side by welding and are juxtaposed, and a striped steel plate 21 having substantially the same width as that between the road surface 19 and the rail 13 is provided. After the presser foot 16 is also installed between the adjacent I-beams 14 and attached, the screw spike 18 is screwed with a wrench through the screw hole 17 formed in the striped steel plate 21, and the presser foot 16 To the sleeper 12 And have, each diamond plate 15 and 21 are to form an a ho Isuzu same level road surface 19 and rail 13.
[0011]
One or more blocks configured as described above are installed according to the length of the level crossing. Reference numeral 23 shown in FIG. 3 denotes a lid which is inserted into and screwed into the screw holes 17 of the striped steel plates 15 and 21. In this embodiment, by removing the lid 23 and removing the screw spike 18 through the screw hole 17, the striped steel plates 15 and 21 are removed for each I-shaped steel 14 and can be repaired or replaced.
[0012]
In the illustrated embodiment, four I-type steels are provided side by side on the striped steel plate 15 and two I-type steels are provided side by side on the striped steel plate 21, but a plurality of other I-type steels may be provided side by side. Not only one side but also both sides may be supported by the presser foot.
[0013]
【The invention's effect】
According to the present invention, the railroad crossing structure is composed of sleepers, rails, shaped steel, steel plates and their fastening and fixing means, the number of parts is small, and not only the crossties and rails but also shaped steel and steel plates are general components. Because of this, it can be provided at low cost, and by bending the shaped steel, it can easily cope with curved railroad crossings. In addition, not only can the frequency of repair be reduced, but also a protective rail for preventing derailment can be omitted.
[0014]
Further, the steel sheet can be easily detached on the sleeper together with the shaped steel by the construction method of the present invention .
