The vertical spindle 30 is vertically inserted into the first shaft hole 12 of the base plate 10 and the fastening groove 61 of the inclination adjustment latch 60 to adjust the rising and falling of the base plate 10. The predetermined section is provided with a screw portion 31, the outer diameter of which is slightly increased compared to other portions. A thread is formed on the outer circumferential surface of the screw part 31 so as to be screwed with the inclination adjustment clasp 60, and may be fixed to the fastening groove 61 of the inclination control clasp 60 at a predetermined position.

The sliding plate 40 is coupled to the upper surface of the base plate 10 so as to be movable left and right. The upper surface of the sliding plate 40 has a seating portion 41 is formed in the form that the rail can be seated, the first stepped portion 42 and the second stepped portion 43 is formed at both ends of the predetermined height, respectively The upper end of the first stepped portion 42 is bent toward the rail to hold the rail. In addition, a screw hole 44 is vertically formed in the second stepped part 43, and the rail is fixed to the sliding plate 40 by the rail fixing member. The rail fixing member includes a rail fixing plate 45 for pressing the rail toward the sliding plate 40 and a fixing screw 46 inserted into the rail fixing plate 45 and fixed to the sliding plate 40. In addition, the bottom surface of the sliding plate 40 is provided with a movement guide 47 integrally so that the horizontal spindle 50 is screwed, the outer peripheral surface of the horizontal spindle 50 on the inner peripheral surface of the through hole in the movement guide 47 The thread is formed to correspond to the thread formed in the thread.

The horizontal spindle 50 is inserted horizontally into the second shaft hole 17 to induce left and right movement of the sliding plate 40. At this time, the outer circumferential surface of the horizontal spindle 50 is provided with a spiral portion 51 over a predetermined section, one side of the spiral portion 51 is rotated to be inserted into the rotation guide groove 27 of the base plate 10 ( 52) is formed. And the other side of the spiral portion 51 is formed with a collar coupling portion 53 is reduced in diameter than the spiral portion 51, the bolt coupling portion 54 is formed extending on one side of the collar coupling portion 53 . Accordingly, the collar 55 is coupled to the collar coupling portion 53 to be inserted into the second shaft hole 17 of the base plate 10, and the bolt head 56 is fixedly coupled to the bolt coupling portion 54. At this time, the bolt coupling portion 54 and the bolt head 56 are firmly fixed to each other by quenching after shrinking.

With reference to Figure 6 will be described the operation of the track stand according to an embodiment of the present invention.

When the vertical spindle 30 is rotated in one direction while the vertical spindle 30 is inserted into and coupled to the fastening groove 60 of the inclination adjustment latch 60, the pin 25 is fixed to the inclination adjustment latch coupling part 21. And the base plate 10 coupled to the inclination adjustment latch 60 by the binding adjustment bolt 70 fastened to the end of the vertical shaft coupling portion 11 is raised or lowered as shown in FIG. 6A.

In addition, when the horizontal spindle 50 inserted into the second shaft hole 17 of the base plate 10 also rotates in one direction, the sliding plate 40 screwed to the horizontal spindle 50 is illustrated in FIG. 4B. As will be moved in the left and right directions.

On the other hand, the inclination adjustment latch 60 can be adjusted to the distance from the base plate 10 by the inclination adjustment bolt 70, the inclination adjustment bolt 70 is placed on the other end 64 of the inclination adjustment latch (60). When the tightening is released, the other end 64 is sliding along the curved surface of the upper surface, so the position of the head of the inclination adjustment bolt 70 can be adjusted and the lower end of the inclination adjustment bolt 70 is the base plate 10 Since the length coupled to the screw groove 13 of the can be adjusted through this the angle between the inclination adjustment latch 60 and the base plate 10 is adjusted.

Referring to FIG. 7, a process of installing a rail using the track stand configured as described above is as follows.

7 shows a rail construction state of the curved section, first of all, the foundation works on the ground to prevent the ground from collapsing, then the gravel is laid on the ground after the foundation work and the sleepers 1 are installed thereon. In addition, the rail (R) is to be installed.

Here, when installing the rail (R) to the sleeper (1) is installed very firmly so as not to twist the rail. That is, the rail is placed on the concrete sleeper (1), the sleeper (1) supports the load of the railroad vehicle transmitted through the rail and absorbs the shock absorbed.

In this case, after the track rail is installed on one rail and the track rail is installed on the other rail corresponding thereto, the base plate is formed by the vertical spindle 30 and the horizontal spindle 50 through the operation of FIGS. 6A to 6C. The height and the left and right spacing of (10) can be precisely adjusted according to the design, thereby obeying the angle of the concrete pattern to be completed afterwards.

Thereafter, the concrete phase 2 is formed. At this time, since the base plate 10 and the sliding plate 40 are firmly in close contact with each other by a fixing screw, the concrete can be prevented from penetrating therebetween. Therefore, it is a matter of course that the rotation operation of the horizontal spindle 50 even after construction.

Here, before forming the concrete phase, the surface of the vertical spindle 30 is coated with grease, which is a lubricant, to form a concrete phase, whereby the vertical spindle 30 can be separated even after the concrete phase is completely cured. In addition, the horizontal spindle 50 and the base plate 10 can be separated.

Therefore, the track pedestal of the present invention can be recycled during another rail construction work, it is possible to significantly reduce the process cost compared to the conventional.

In addition, the present invention by adjusting the left and right movement of the base plate 10 is fixed to the rail on the sleeper, even if the arrangement of the sleepers arranged on the figure shifts the rail by moving only the base plate 10 without moving the sleeper Since it can be fixedly installed, the construction time and cost can be saved. In particular, the sleeper can be accurately aligned to the installation position of the rail in a curved section by elevating the base plate 10 or horizontally moving the sliding plate 40. In addition, since the inclination angle of the base plate 10 can be adjusted using the inclination adjustment bolt 70, there is an advantage in that the gauge is easily adjusted.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
