Railroad sleepers refer to sleepers made of wood or concrete, which are laid under the rails in order to fix the rails in a predetermined position on the track and to distribute the load of the trains received from the rails to the road.

Here, the railroad sleepers were generally formed in a straight shape, and most of them were arranged in a right angle direction of the rail (refer to the Utility Model Registration No. 20-0264304).

Recently, however, various types of sleepers have been proposed that are effective and competitive in terms of stability, durability, and ease of installation of railroad cars, economical efficiency, and future maintenance. (See Japanese Utility Model Publication No. 50-148702). (Published Dec. 10, 1975), Japanese Patent Application Laid-Open No. 09-273102 (published Oct. 21, 1997), and Korean Registered Patent No. 0070225 (August 03, 2007)

These conventional straight sleepers and sleepers for multi-stage railroads and Japanese Utility Model Publication No. 50-148702 (published Dec. 10, 1975) have the following problems.

Conventional straight rail sleepers are vulnerable in terms of safety of the track, such as vulnerable to the lateral resistance and longitudinal resistance, causing the long run of the track threatening the safe operation of the train.

In the case of the conventional multi-stage railroad sleeper, firstly, due to the complexity of the shape, not only the production is difficult but also the manufacturing cost increases. Second, there is a problem in that the length of the sleeper has a limit in increasing the transverse resistance and the longitudinal resistance, and finally, the line is settled because it is not drained by the sleeper transverse supports on both sides of the central connection. The problem remains a lot of trouble.

In addition, the conventional sleepers for railroads have difficulty in maintenance due to the twisting of the track and frequent track twisting due to the straight shape, which is a major cause of deterioration of ride comfort, and the twisting phenomenon is caused by the three-point support of the train bogie. There is a problem of derailment.

Japanese Unexamined Utility Model Publication No. 50-148702 (published Dec. 10, 1975) The sleepers did not function well as sleepers due to poor drainage, which promoted the generation of bunnies and required twisting and frequent repairs. And it was proved that there was no economic feat of sleepers because it was difficult to work with multiple typ stamps, ballast cleaners, ballast compacts, etc., which were large repair equipments of the track. In this way, the sleepers should be designed to support the rails, to facilitate drainage, and to be able to work with large-scale maintenance equipment while increasing the longitudinal and lateral resistances to ensure safe operation of the train.

1 and 2, the railroad sleeper T of the first embodiment is installed at a lower portion of the rail 100. Railroad sleepers (T) are buried surrounded by donor gal (P) to expose the upper surface.

Referring to Figure 3 railway sleepers (T) is formed to form an H type. Railroad sleepers (T) includes two straight main pedestal 200 and the donor gal resistance band (300). The two straight main pedestals 200 are spaced apart from each other in the width direction. The railroad sleepers T form an H-shape by connecting the center portion of the two main pedestals 200 with each other. Since the present invention forms an H shape, the transverse displacement of the rail is reduced and the bending force along the longitudinal direction of the rail is reduced.

2 and 3, the rail 100 is seated and fixed on an upper surface of the main pedestal 200. In order to fix the rail 100, shoulders 400 are respectively installed on both sides of the rail support part 200R on which the rail 100 is seated, among the upper surfaces of the main pedestal 200.

Referring to FIG. 4, the rail support part 200R formed on the upper surface of the main pedestal 200 is formed in a plane. Therefore, since the rail 100 is seated and fixed to the flat rail support 200R having no inclination, track inaccuracy, noise and vibration are reduced, and uneven wear of the rail 100 is reduced, thereby increasing the life of the rail 100. .

Referring to Figure 3, the railroad sleepers (T), since the two main pedestal 200 is connected by the donor galvanic resistance 300, an opening is formed between both ends of the two main pedestal 200 is good drainage Is done. Therefore, it is possible to prevent the occurrence of Bunny in the track, reducing the track wrong.

3 and 4, the reinforcement part 500 having a triangular horizontal cross section is further along the vertical direction at a corner portion where the main pedestal 200 and the donor gal resistance band 300 are connected to each other and formed in the vertical direction. Is formed to protrude.

Referring to FIG. 4, the reinforcement part 500 includes an exposed surface 510 exposed to the outside. On the other hand, one end 511 of the exposed surface 510 is rounded in the horizontal direction and connected to the main pedestal 200, the other end 512 of the exposed surface 510 is rounded in the horizontal direction and It is connected to the gravel resistance band (300). As both ends 511 and 512 of the exposed surface 510 are rounded, the railroad sleepers T and the donor gal P closely adhere to each other, and both ends 511 and 512 of the exposed surface 510 are smoothly adhered to each other. Its rigidity against breakage is enhanced.

On the other hand, the main pedestal 200 is made of PC (prestressed concrete), the donor gal resistance band 300 is made of RC (reinforced concrete). The reason for producing the donor galvanic resistance 300 in RC (reinforced concrete) is to reduce the loss of the PC steel wire and to avoid the complexity of the production.

PC (prestressed concrete) is a structure for increasing the force to withstand the external force when used by pre-stressing the member using a piano wire or special steel wire. In general, concrete is subjected to tensile strain, and cracks often occur. If such compressive force is applied to a member such as a piano wire in advance, the tensile strain is canceled by compressive deformation force such as a piano wire. As a result, the member itself is not subjected to substantially large tensile strain.

RC (reinforced concrete) is a structure that stores the weakness of tensile stress of concrete with rebar. In other words, the compressive force of the concrete and the tensile force of the reinforcing bar are integrated with respect to the external force, so that the defects can be complemented with each other. RC (reinforced concrete) structure is made of wooden boards or iron plates in the form of beams, walls, pillars, etc., and the necessary reinforcing bars are pre-assembled and poured concrete to stiffen the concrete so that the required strength is achieved. If you wait until the mold is demolded, a RC (reinforced concrete) member is created.

Referring to FIG. 6, four longitudinal reinforcing bars 310 are disposed in the donor galling resistor 300 to form a rectangular lattice shape along the longitudinal direction of the donor galling resistor 300. In addition, when looking at the cross-sectional cross-section of the donor gal resistance band 300, the widthwise reinforcing bar 320 is disposed to surround the four longitudinal reinforcing bars 310 arranged in the longitudinal direction. Width reinforcing bars 320 are spaced apart from each other and are arranged in plurality. Referring to FIG. 5, eight widthwise reinforcing bars 320 may be disposed, including those arranged on the main pedestal 200.

5 and 7, a plurality of 16 steel wires 230 are disposed along the longitudinal direction of the main pedestal 200 in the main pedestal 200. As described above, concrete may be poured in a state in which tensile force is applied to the plurality of 16 steel wires 230.

Referring to FIG. 7, upper inclined surfaces 210 and lower inclined surfaces 220 are formed on both side surfaces of the main pedestal 200 in the width direction. The upper inclined surface 210 is formed to be inclined outward while going downward from the top of the main pedestal 200. The lower inclined surface 220 is connected to the lower end of the upper inclined surface 210 and is inclined in an outward direction while going downward with a larger inclination than the upper inclined surface 210. The reason why the inclination angle of the lower inclined surface 220 is increased in the inclined surface of the upper inclined surface 210 is that the donor gal (P) presses the main pedestal 200, thereby preventing the up and down flow of the track, thereby reducing the inaccuracy of the track and the riding comfort. Is to make it good.

Referring to FIG. 4, the width W of the donor gal resistance band 300 is formed to be 30 to 50 cm. This is for the distance (d) from the both sides in the width direction of the donor gal resistance band 300 to the rail support portion 200R formed on the upper surface of the main pedestal 200 is 40 cm or more. That is, since the distance (R) between the rails 100 is determined to be 143.5 cm, the width (W) of the donor galvanic resistance band 300 should be less than 30 ~ 50cm, the main pedestal from both sides in the width direction of the donor galvanic resistance band (300) The distance d to the rail support part 200R formed in the upper surface of 200 becomes 40 cm or more, respectively. By designing the width W of the donor galvanic resistance band 300 to 30 to 50 cm, it is possible to operate a large-scale maintenance machine using a multiple tietemp, a barast cleaner, a barast compact, a barast regulator, and the like. On the other hand, the main pedestal 200 may be formed so that the length (L) is 240cm.

Referring to FIG. 6, a recess 330 having a predetermined cross-sectional shape is formed in the donor gal resistance band 300. The recess 330 is engraved in the upward direction from the bottom surface in the donor gal resistance band 300. The recess 330 may be a semicircular shape of the tip portion located at the upper end thereof, and a circumferential surface from the tip portion to the opening portion located at the bottom portion thereof may be conical or parabolic. The tip portion of the recess 330 is manufactured in a semicircular shape to increase the lateral resistance and the longitudinal resistance of the statue, and to prevent the damage of the donor gal resistance band 300. On the other hand, since the recess 330 is formed in the box gal resistance band 300, the friction force between the box gal resistance band 300 and the box gal (P) is increased.

The flow preventing protrusion 700 protrudes in the longitudinal direction of the rail 100 on the outer side in the width direction of the main pedestal 200, and is formed to be positioned on the longitudinal extension line of the donor rib 300. When the railroad sleeper T is installed, the flow preventing protrusion 700 is connected to or connected to the main pedestal 200 of the railroad sleeper T installed adjacent to each other.

The flow preventing protrusion 700 is in contact with or connected to the main pedestal 200 of the railroad sleeper T, which is installed next to each other, thereby increasing the force that obstructs the movement of the railroad sleeper T as a whole. In addition, the movement along the longitudinal direction of the rail 100 is relatively much smaller and the movement due to the vehicle load is smaller, so that the safety of the vehicle and the track inaccuracy of the track are small, which is advantageous to the maintenance management. have. A shock absorbing material 710 may be attached to the front end of the flow preventing protrusion 700.
