BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

FIG. 6 is a plan view showing the construction of a railway sleeping rail reinforcing apparatus according to an embodiment of the present invention, FIG. 7 is a partially enlarged plan view of FIG. 6, and FIG. 8 is a transverse sectional view of a sleeping portion in FIG.

Fig. 9 is a configuration diagram showing a state in which a sleeper is bound by an L-shaped engagement member, and Fig. 10 is a front view of an L-shaped engagement member for fixing a longitudinal reinforcement band to a sleeper by a clamp unit.

6 and 8, a reinforcement device 100 of a railway railway railway railway rail 140 according to an embodiment of the present invention includes a plurality of railway rails 110 disposed at regular intervals on a ground, A pair of rail rails 140 fixed in parallel to each other in a direction orthogonal to the upper ends of the plurality of sleepers 110 and a longitudinal reinforcement 120 arranged between the pair of rail rails 140, As shown in FIG.

At this time, the pair of rail rails 140 may be fixedly installed by the first joint units 112 installed on both sides of the sleepers 110.

The longitudinal bars 120 may have a substantially I-shape, and the longitudinal bars 120 may be disposed to be vertically crossed with each other.

The reinforcing device of the railway rail 140 according to the embodiment of the present invention may further include a fixing support for fixing the longitudinal support bars 120 to the middle ends of the timbers 110. [

Here, the stationary support includes a horizontal lid for covering the upper portion of the longitudinal support bar 120, side portions for bending the side portions of the longitudinal reinforcement rods 120 so as to be bent in the vertical direction from both ends of the lid portion, And a clamping unit 130 configured to be bent in the horizontal direction and fixed to and coupled to the sleepers 110 by the joining members 200 to be described later.

In addition, the stationary support may include engagement members 200 that securely couple the clamp unit 130 to the sleepers 110, and the engagement member 200 will be described in detail later.

The clamp unit 130 constituting the fixed support may have a lid portion, a side portion, and a fixing portion integrally formed. In this case, the width of the clamp unit 130 may be larger than the width of the sleepers 110.

6, the clamp unit 130 is formed such that the width of the clamp unit 130 is somewhat longer than the width of the middle end of the sleeper 110 with respect to the installation direction of the railway rail 140 and the longitudinal reinforcement member 120 .

Therefore, the both ends of the fixed unit of the clamp unit 130 are exposed to the outside so that the front and rear edge portions do not interfere with the sleepers 110 when viewed in a plan view. At the corner of the fixing unit, .

The coupling unit 200 is inserted through the coupling holes so that the clamp unit 130 and the sleepers 110 are inserted into the clamp unit 130, So that the longitudinal bars 120 are stably fixed and coupled in a state in which the longitudinal bars 120 are disposed in a direction orthogonal to the sleepers 110. This will be described as follows.

8 to 10, the coupling member 200 includes a vertical support portion 210 to be inserted into a coupling hole of the clamp unit 130, and a bent portion extending in a direction perpendicular to the vertical support portion 210 And a horizontal support 220 formed to be L-shaped.

In this case, although the vertical supporting portion 210 of the coupling member 200 does not have a separate threaded portion, the vertical supporting portion 210 may have a predetermined length Can be applied, and the fastening can be performed by a nut or the like.

In the coupling member 200 having such a configuration, the horizontal support portion 220 is held in close contact with the bottom surface of the sleeper 110, and the vertical support portion 210 is supported in close contact with the side surface of the sleeper 110 have.

Accordingly, when the longitudinal bar 120 is disposed in the direction in which the sleeper 110 is staggered and the clamp unit 130 is seated in the same linear area as the sleeper 110 when viewed in plan, The edge portions of the fixing unit of the clamp unit 130, that is, the edge portions where the fixing holes are formed, do not overlap with the middle portion of the sleepers 110 (See Fig. 6)

In this state, the clamp unit 130 and the sleepers 110 are combined as the L-shaped engagement members 200 for each engagement hole.

First, the tip of the vertical support portion 210 of the coupling member 200 is inserted below the fixing portion of the clamp unit 130, through the coupling hole of the fixing portion.

At this time, the horizontal support portion 220 of the coupling member 200 is inserted in the inner direction so as to be in close contact with the bottom surface of the sleeper 110.

When a nut or the like is tightened at the tip of the vertical support portion 210 of the coupling member 200 exposed upward through the coupling hole of the clamp unit 130 and then tightened by tightening the nut or the like, 130 and the horizontal support portion 220 of the coupling member 200 so that the clamp unit 130 is held in a state of being coupled to the sleepers 110 by the coupling member 200.

In this case, as the nut is strongly tightened, the horizontal support portion 220 of the coupling member 200 is increased in adhesion with the bottom surface of the sleeper 110, so that the clamp unit 130 is stably fixed to the sleeper 110 State.

Accordingly, the longitudinal support bars 120 are also stably fixed by the strong adhesion between the lid portion and the side surface of the clamp unit 130 and the upper surface of the sleepers 110, so that the binding force can be greatly improved.

As the coupling member 200 is engaged with the corners of the fixing unit of the clamp unit 130, the clamp unit 130 can be more stably fixed to the sleepers 110 by four-point support .

For reference, in FIG. 10, reference numeral 230 denotes a welded portion joined to the sleeper 110 by welding or the like.

As described above, according to the reinforcement device and the reinforcing method of the railway rail fastening rail 140 according to the embodiment of the present invention, since the longitudinal rail 120 is directly fixedly coupled to the railway railroad tie 110, The number of parts is reduced, so that the construction cost is lowered, and the workability is also greatly improved due to the reduction of the number of assembly operations.

In other words, conventionally, in order to stably fix the longitudinal support bars 120, a separate lateral support bar is provided and the pair of rail rails 140 are fixed to the lateral support bars, According to the reinforcement device of the railway rail 140 according to the embodiment of the present invention, since the longitudinal barb 120 is directly fixedly coupled to the sleepers 110, The cost of construction can be reduced according to the reduction in the number of parts, and the workability can be greatly improved due to the reduction of the number of assembly operations.

According to the reinforcement device and the reinforcing method of the railway rail 140 according to the embodiment of the present invention, since the longitudinal reinforcement rods 120 are fixedly coupled to the railroad ties 110, A sufficient space between the sleepers 110 and the railway rails 140 can be sufficiently ensured around the intersection of the railway rail 140 and the railway rail 140 so that there is no fear of deformation or settlement of the railway rail 140 Effects can also be provided.

13A to 13F are views showing a rear compaction portion in a state where a reinforcing device of a railway rail fastening rail 140 according to an embodiment of the present invention is applied. As shown in FIG. 13, The reinforcing device of the railway rail 140 does not include the structure of the transverse reinforcements separately disposed between the railway rails 140. As a result, 8 points can be chopped.

That is, in a state in which a pair of railway rails 140 are installed for a plurality of the sleepers 110, as shown in FIGS. 13A to 13D, at eight points intersecting the railway rail 140 per sleepers 110 Compaction must be carried out.

Of course, depending on the line condition, working conditions, working time, etc., it is possible to compose six places or four places, as shown in Figs. 13E and 13F, but basically eight places are compaction.

For reference, the portion indicated by O in the drawing indicates the first compaction, and the portion indicated with X indicates the rear compaction.

However, conventionally, in order to stably fix the longitudinal bar reinforcement 120, since a separate transverse bar is provided between the timbers 110, the space between the timbers 110 is infiltrated and narrowed, The compaction of eight places can not be carried out as in the embodiment of the present invention, so that it is impossible to eliminate the risk of deformation or settlement of the rail rail 140. On the other hand, in the present invention, It is possible to eliminate the risk of deformation or settlement of the rail rail 140 due to compaction.

11 is a perspective view showing another type of L-shaped engagement member that fixes the longitudinal reinforcement bar to a sleeper by a clamp unit, and FIG. 12 is a front view showing a configuration in which the L-shaped engagement member shown in FIG. 11 is variable in length The coupling member 300 may be configured such that the vertical support 320 is variable in length.

For example, there is no problem if the thickness of the sleepers 110 is constant, but the thickness of the sleepers 110 may be different depending on the installation position of the rail rails 140.

As described above, when the thickness of the sleepers 110 is different, a coupling member corresponding to the thickness of the sleepers 110 must be provided. In order to correspond to different thicknesses of the sleepers, the length of the coupling members 300 may be varied can do.

The vertical support portion 320 of the coupling member 300 may include a first support portion 310 having a threaded portion 312 and a second support portion 322 having a threaded hole 324, The length of the vertical support part 320 can be varied by fastening the screw part 312 of the support part 310 and the screw hole 324 of the second support part 322.

In this case, the horizontal support portion 326 may be bent in a direction intersecting with the second support portion 322.

In order to prevent the first supporting part 310 and the second supporting part 322 from being separated from each other in a state where the clamping unit and the sleeper are coupled by using the coupling member 300, .

For reference, in FIG. 12, reference numeral 330 denotes a welded portion joined to the sleeper by welding or the like.

The configuration and method of coupling the clamping unit and the sleeper using the coupling member 300 shown in Figures 11 and 12 differ only in varying the length of the vertical support 320 of the coupling member 300, The rest of the configuration and the coupling method are the same, and a repetitive description thereof will be omitted.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
