The collar washer 122 is a rail pad seated between the rail R and the base plate 108.

Hereinafter, the operation of the rail fastening device using a concrete sleeper RC sleeper according to the present invention will be described in more detail with reference to the accompanying drawings.

2 and 3, the RC steel rod 101 and the truss-shaped reinforcing bars 102 are fixed or welded at predetermined intervals in the sleeper frame not shown, and the dustproof fasteners 103 and 104 are coupled to each other. A non-illustrated round bar having a predetermined diameter is installed at a predetermined position so that through holes 105 and 106 are formed.

After curing the concrete in the sleeper mold for a predetermined period of time, the double RC sleepers 100 to maintain a predetermined interval by the RC steel rod 101 and the truss-type reinforcing bars 102 is completed.

Therefore, when the RC sleeper 100 is transported to a predetermined section where the rail R is installed, and the concrete bed 121 is poured in a horizontal manner, the installation work of the RC sleeper 100 is completed, and at this time, the RC sleeper 100 After coupling the dustproof fasteners 103 and 104 to the formed through holes 105 and 106, the concrete pattern 121 is poured into the dustproof fasteners 103 and 104 to the RC sleepers 100 to be integrally fixed.

At this time, by placing the buried portion 119 of the slab for slab and RC sleeper 100 at the same height level, the work is facilitated as the concrete is poured.

On the other hand, as shown in Figures 1 to 3, the RC steel bar 101 and the truss-type reinforcing bars 102 are projected by a predetermined length on the left and right side surfaces of the RC sleeper 100 when the concrete statue 121 is placed when pouring Reinforcing bars embedded in the slab for the RC steel rod 101 and the truss-type reinforcing bars 102 can be easily fixed or welded connection.

Accordingly, the dustproof pad 115 is seated on the rail fixing step 109 of the RC sleeper 100, and the baseplate 108 is seated on the dustproof pad 115, but formed on the left and right sides of the baseplate 108. The through hole 117 is coupled to the dustproof fasteners 103 and 104.

Meanwhile, as shown in FIGS. 3 and 8, the protrusion 111 formed in the base plate 1080 corresponds to the shape of the groove 110 formed on both sides of the rail fixing step 109 of the RC sleeper 100. ) Can be prevented from rolling in the longitudinal direction when the train is running.

Accordingly, as shown in FIGS. 2, 3, and 8, the rail R is seated on the rail pad 122 seated on the base plate 108, and then diagonally disposed on the upper surface of the base plate 108. The fixing operation of the rail R is completed by coupling one end of the pendroll clip 107 to the formed coupling hole 116 and fixing the other end thereof to press the rail R left and right flanges.

Because of this, the load and vibration generated during the train operation is widely distributed through the concrete bed 121 via the rail (R), RC sleeper 100 is transmitted to the roadbed to increase the durability of the RC sleeper 100, etc. The service life can be extended.

In addition, as shown in FIGS. 5 to 7, the RC by the truss-shaped reinforcing bars 102 are embedded and connected to the RC steel bar 101 is embedded to connect the double-type RC sleepers 100 to maintain a predetermined interval Since the strength of the sleeper 100 is further increased, it can be used semi-permanently.

On the other hand, RC sleepers for concrete according to the present invention can be used in a variety of sections, such as bridges or tunnels.

When concrete sleeper RC sleeper is used in general section type, it can be applied to tonoban and tunnel section and can be installed in the same way as existing RC sleeper. RC sleeper 100 is connected to the three RC steel rods 101 and the truss-type reinforcing bars 102, each independently placed inside both ends of the RC sleeper 100, embedded, and penetrated formed on the left and right sides of the RC sleeper 100 By increasing the integration of the anti-vibration fasteners 103 and 104 and the RC sleeper 100 by coupling the anti-vibration fasteners 103 and 104 to the balls 105 and 106, it has an advantage of being lighter and easier to handle than the existing sleepers.

When concrete sleeper RC sleeper is used in connection section type, the reinforcement structure of RC steel bar embedded in sleeper is the same as the above general section type, and it is common inside sleeper to connect the sleeper and sleeper to prevent bending of the rail. The through hole is formed to install the fastener and other fasteners.

When concrete sleeper RC sleeper is used in bridge section type, the strength and durability of RC sleeper is improved by installing an angle that maintains a predetermined interval next to this rail to sufficiently support the external pressure applied during train operation. Increased has the advantage that can prevent the train derailment.

As described above, the rail fastening device using the RC sleeper for concrete bed according to the present invention has the following advantages.

It is possible to use the sleepers semi-permanently by connecting the truss-type reinforcing bars to be embedded after RC truss embedded in the molding of concrete sleepers, and to secure structural stability by integrating the sleepers and the slab for drawing. I would have to.

In addition, the concrete sleepers can be used by applying to the general section type, connection section type and bridge section type, respectively.

In addition, due to the reduction in the cross-sectional area of the concrete sleeper, lightweight, easy to transport and easy to work, greatly improves the workability and workability, and excellent maintenance and repair.

In addition, the RC rods buried beneath the concrete sleepers and the concrete protrusion structures extending to the left and right sides of the sleepers distribute and accommodate the high loads generated when the rail is running. Can be exercised.
