Description

Technical Field [0001] The present invention relates to a sleeper embedding type girder and a construction method thereof,

More particularly, the present invention relates to a sleeper-embedding type girder and a construction method thereof, and more particularly to a girder which is extended in a longitudinal direction (train running direction) so that an opening (pocket) into which a sleeper can be inserted is extended laterally And a guide rail-tie rail assembly composed of a guide rail and a tie rail is mounted on the girder so that the tie rail is inserted into the opening of the girder so that the load applied from the guide rail is directly applied to the girder as well as the tie rail, , It is possible to simplify the installation of the sleepers, thereby reducing the construction cost and the effect of shortening the air and reducing the maintenance cost. In addition, the stability of the sleepers can be improved by completely blocking the flow of the sleepers in the longitudinal direction, The bridge structure can be used to reduce the overall shape of the bridge overhead structure. "A sleeper-embedding type girder and a construction method thereof ".

In the case of a magnetic levitation train in which a train runs on a train, the train is made to float on a trajectory by using magnetic force, and a plate-shaped guide rail for supporting the magnetic force device provided on the train in a noncontact manner is provided. Korean Patent No. 10-1040102 discloses an example of a conventional technique for installing a guide rail for a magnetic levitation train.

However, in the prior art, when the guide rail is installed on the girder, the transversely extending sleepers perpendicularly to the longitudinal direction are arranged transversely on the upper surface of the girder of the bridge, and the guide rails are connected to both ends of the sleepers. Fig. 1 shows a structure in which a sleeper 3 is placed on the upper surface of a steel girder 1 having a box-shaped cross section in the longitudinal direction according to the prior art, There is shown a schematic perspective view showing a configuration in which guide rails 2 extending in the longitudinal direction are provided at both ends in the transverse direction.

In such a conventional technique, the sleepers 3 should be spaced apart from one another in the vertical direction on the upper surface of the strong-type girder 1. In order to prevent the sleepers 3 from moving in the longitudinal direction, It is necessary to tightly fasten the upper surface of the girder girder 1 to the upper surface. However, in the related art, since all of the loads applied from the guide rails 2 are primarily supported by the sleepers, the sleepers must be tightly installed with a very narrow interval in the longitudinal direction, And the fastening operation for joining the respective sleepers to the upper surface of the strong-type girder should be carried out at a very large number of times. Therefore, the above conventional art has a disadvantage in that the overall construction cost, such as the work cost required for the fastening operation and the purchase cost of the fastening device, is increased.

Also, since the conventional technique is coupled to the upper surface of the high-strength type girder in many places where the sleeper is present, there is also a disadvantage that the maintenance management cost is also increased because the maintenance required for the connection between the sleeper and the high-grade type girder is also increased.

Further, in the prior art, since the tread is placed on the upper surface of the strong-type girder, the overall height of the bridge overhead structure including the height of the member such as the guide rail and the track protruding above the girder and the height of the strong- Thereby causing disadvantages in usability and aesthetics.

Further, in order to achieve the above object, the present invention includes a top plate and side walls on both sides in the transverse direction, wherein a plurality of openings extending in the transverse direction are formed on the top plate of the strong- A step of fabricating a gantry type girder in which a recess is formed in an upper end of a side wall at an opening formed in the opening, And a pair of guide rails, each of which is provided integrally with the inner side of the inner side, and a lower side of the inner side of the inner side of the upper side of the upper side, And a step of joining the guide rail and the tie rail integrally with each other.

In the girder and the construction method of the present invention, when the tie rail is mounted and the guide rail is mounted to be coupled, a plurality of tie rods are arranged in the longitudinal direction so as to have an interval corresponding to the spacing of the opening portions, After assembling the guide rail-tie rail assembly with both ends and a pair of guide rails, the pre-fabricated guide rail-tie rail assembly is transported to the upper portion of the steel gauge type girder so that the tie rail is positioned in the opening and recess, The lower surface of the stone plate can be brought into close contact with the upper surface of the upper plate.

According to the present invention, the movement of the sleepers in the longitudinal direction is intrinsically blocked, and the sleepers can be stably installed.

In the present invention, since the treadmill is supported by the steel-type girder and the guide rail itself is directly supported by the steel-type girder, the load from the guide rail is directly applied to the steel-type girder, The size of the sleepers can be reduced, and the installation place of the sleepers can be reduced.

Particularly, according to the present invention, the installation place of the sleepers is reduced as compared with the prior art, so that the operation of combining the sleepers and the guide rails can be simplified and accelerated as well as the amount of the material used for the sleepers can be reduced Not only can the construction cost reduction and the air shortening effect be attained, but also the number of the sleeping places requiring the maintenance is reduced, so that the maintenance cost can be saved.

As shown in FIG. 3, the strong-type girder 1 has a box-shaped cross section including a top plate 10 forming an upper surface, side walls 13 located on both sides in a lateral direction and a bottom plate, In the upper plate 10 of the girder 1, there are formed a plurality of openings (pockets) 11 in which longitudinally spaced sleepers can be inserted. The opening 11 is formed to extend over the entire width of the upper plate 10 in the transverse direction. When the opening 11 is formed as described above, the concave portion 12 is formed in the upper portion of both side walls 13 in the transverse direction forming the box end face of the rigid-type girder 1 so that the lower portion of the sleeper can be fitted. Fig. 4 shows a schematic enlarged view of the circle A portion of Fig. 3, in which the upper portions of both side walls 13 of the strong-type girder 1 are folded at a position where the opening 11 is formed, The concave portion 12 communicating with the opening 11 is formed on each of the side walls 13. In this case,

The transversely extending sleepers 3 are inserted and positioned in the openings 11 and the recesses 12 and the upper portions of the transversely opposite ends of the sleepers 3 are provided with guides The rail 2 is engaged. The guide rail 2 can be assembled to the sleepers 3 after the sleepers 3 are inserted into the openings 11 but the sleepers 3 are integrally joined in advance to the pair of guide rails 2 It is preferable that the guide rail-tie rail assembly having the guide rail-tie rail assembly is preliminarily manufactured and then transferred onto the steel-frame type girder 1 so that the tie rail 3 is inserted into the opening 11.

Fig. 5 is a schematic perspective view showing a state in which the pre-fabricated guide rail-tie assembly is mounted on the strong-type girder 1. Fig. A plurality of transversely extending sleepers 3 are mounted on the lower surface of a pair of guide rails 2 arranged side by side with a spacing according to design in the lateral direction, And the guide rails (2) are assembled and coupled to the transversely opposite ends of the sleepers (3), respectively, by preliminarily manufacturing the guide rail-tie assemblies in advance. That is, a pair of guide rails 2 are installed at both upper and lower ends of the sleepers 3 in a state in which a plurality of sleepers 3 are arranged at intervals corresponding to the intervals of the openings 11 in the longitudinal direction And the guide rail-tie assembly is assembled in advance.

The pre-fabricated rail-tie assembly is then moved over the steel-type girders 1 as shown in Fig. 5 so that the rail-tie assembly from above the steel-type girders 1 is inserted so that each tie- .

6 is a schematic perspective view showing a state in which the guide rail-tie assembly is mounted on the upper portion of the steel-frame type girder 1. In Fig. When the rail-tie-down assembly is mounted on the upper portion of the steel-frame type girder 1 as described above, the tie rail 3 is positioned in the opening portion 11. As described above, The lower portion of the sleeper 3 is positioned at the recess 12 at both lateral ends of the sleeper 3 when the portion 12 is formed. The vertical depth of the concave portion 12 is appropriately selected so that the upper surface of the sleeper 3 is positioned at the same height as or lower than the upper surface of the upper plate 10 of the strong type girder 1, It is preferable not to protrude above the top plate 10 of the girder 1.

Each of the guide rails 2 is integrally provided with an inner side protrusion 21 having a predetermined transverse width on the side in the direction facing each other. In this case, as described above, The lower surface of the inner side stone plate 21 of the guide rail 2 is inserted into the opening portion 11 such that the lower portion is inserted into the recessed portion 12 of the upper frame type girder 1, (Not shown). At this time, if necessary, the inner protrusion 21 of the guide rail 2 and the top plate 10 may be integrally fastened to each other by using fastening means 20 such as a wrench or a bolt member. That is, the fastening means 20 is passed through the inside protrusion 21 and the top plate 10 and fastened to each other, thereby firmly integrating the inside protrusion 21 and the top plate 10. In this way, before the guide rails 2 and the upper plate 10 are integrally fastened to each other by the fastening means 20, the sleeper 3 is placed in the opening 11, You can also perform any necessary adjustments.

The installation of the guide rail-tie-down assembly described above and the coupling with the strong-type girder 1 are completed, thereby completing the construction of the tie-in type girder 100 for a magnetic levitation train according to the present invention as shown in Fig.

In the present invention as described above, since the sleepers 3 are located in the openings 11 and the recesses 12, movement of the sleepers 3 in the longitudinal direction is intrinsically blocked and stable installation of the sleepers 3 is possible There are advantages.

Particularly, as described above, the sleepers 3 are positioned in the openings 11 and the recesses 12 so that the sleepers 3 are supported by the strong-type girders 1 and at the same time, The upper surface of the upper plate 10 of the thin plate type girder 1 is brought into close contact with the lower surface thereof. That is, the treadmill 3 is supported by the strong-type girder 1, and at the same time, the guide rail 2 itself is supported together by the strong-type girder 1. [ The load applied from the guide rail 2 is transmitted to the sleeper 3 but since the guide rail 2 is in a state of being directly held in tight contact with the steel type girder 1, It is also directly applied to the stiff girder 1. Therefore, the load to be borne by the sleepers 3 with respect to the load from the guide rails 2 is reduced, and accordingly, the places where the sleepers 3 are installed can be reduced. That is, the load from the guide rail 2 is transmitted to the strong-type girder 1 through the sleepers 3, but the inner styrene sheet 21 is directly brought into close contact with the top plate 10, It is also transmitted.

As described above, according to the present invention, since the location of the sleepers 3 is reduced compared to the prior art, it is possible to reduce the amount of material used for the sleepers 3, The work can be simplified and proceeded quickly, thereby reducing the construction cost and shortening the work time. Furthermore, the reduction in the number of places where the sleepers 3 are installed means a reduction in the number of locations where maintenance is required, thereby reducing the maintenance cost.

In the present invention, since the sleeper 3 is inserted into the opening 11, the sleeper 3 is not placed on the upper surface of the top plate 10 but the lower surface of the sleeper 3 is positioned below the top plate 10 . Therefore, the overall height of the bridge overhead structure including the sleepers 3, the guide rails 2, and the steel-frame type girders 1 is significantly lower than that of the conventional art, and thus the advantageous effects are obtained in terms of usability and aesthetics.

As described above, in the description of the present invention, a guide rail 2 used for a magnetic levitation train is exemplified as an example of a rail coupled with a sleeper 3. However, in the present invention, . That is, as long as the inner side draft plate 21 is provided on the inner side of the rail, not only the maglev train guide rail 2 but also a general rail having longitudinal section of the letter I shape running on a general train wheel can be applied It is.
