The upper rail is provided with a flat upper plate on the lower side of the rail, which is provided on a generally curved portion of a known railway line. A rail brace for supporting and fixing one end of the rail is supported and fixed by a pen- And the guard rail is provided on the other side with a predetermined distance therebetween and is provided with a pen-and-roller clip.

In the conventional rail guard portion having such a configuration, a base rail is provided on an upper portion of a railway track, and a rail brace is disposed on one side of the rail, And the rail brace is fixed to the upper plate using a pen-and-roller clip.

On the other hand, the guard rail is located on the opposite side to the rail brace on the other side of the base rail and is spaced apart from the base rail by a predetermined distance, and then fixed with the pen rail clip. The wheels of the train are guided to the guard rails, and the basic rails, which receive a great deal of load and pressure, are held by the rail braces.

However, the speed and centrifugal force of the train are relatively strong at the curved portion of the line, and the train is pushed to the outside of the basic rail by the lateral pressure by the centrifugal force, thereby causing derailment and overturning of the train There are disadvantages.

Particularly, in order to stably guide the railway wheels of such a line-like curved portion, a separate guard rail is provided at one side of the basic rail, and the guard portion is complicated due to the rail brace being fastened to one side surface of the basic rail. It is difficult to manufacture and install the same, and the installation cost is increased.

In order to solve such a problem, in the Utility Model Registration Application No. 20-2000-0011580, it is not necessary to provide a separate guardrail on the curved portion of the railroad track, and the guard for preventing derailment of the train is installed and installed by installing the angle for the guardrail So that the installation cost can be reduced.

The other end of the lower fixture 10 is detachably fixed to the lower end of the vertical fixture 20 so that the vertical fixture 20 fixes the lower end of the rail 1-2 and the vertical fixture 20 The guard angle 5 is fixed to the vertical fixed body 20 while the angle fixed body 30 is fixed to the vertical fixed body 20.

1 to 6, the lower fixture 10 includes a vertical portion 12 and an inclined portion 13 at both ends of the horizontal portion 11, and the vertical portion 12 is formed at an inner side And an engaging groove 12-1 is formed in the engaging groove 12-1 so as to be engaged with the lower rail inner end 1-1.

It is preferable that the inclined portion 13 is integrally formed to be inclined downward in the horizontal portion 11, and the inclination angle is inclined by 30 to 60 degrees in the horizontal direction. However, it does not have to belong to this range. The inclined portion 13 closely contacts the inclined portion 13 to disperse the load applied to the vertical fixture 20 to be fixed to the lower fixture at the lower end of the vertical fixture.

A pair of reinforcing ribs 14 are formed on the bottom surface of the horizontal portion 11 of the lower fixture 10 in the longitudinal direction and the reinforcing ribs 14 are formed so as to correspond to the force of the inclined portion 13 being pushed back, (13) is prevented from being broken. The reinforcing ribs 14 are used as bolt fastening means to form the gap between the reinforcing ribs 14 so that the heads of the bolts 40 are inserted between the reinforcing ribs 14 and are not rotated. These intervals can be designed according to the size of the bolt head used.

The vertical fixing body 20 is formed with a fastening portion 22 at the lower end of the body 21 and the fastening portion 22 is inclined at the same angle as the slanting portion 13 so as to abut the slanting portion 13 And is fixed with the bolt 40 and the nut.
