However, the road extension of Korea is 105,931km as of 2011, but the extension of the protection fence is about 21,000km, which is about 20% of the total road extension, and about 19,000km (90%) is the protection fence applied the previous standard. This can be regarded as an unprotected protection fence to which standard specifications were applied before recent performance evaluation standards such as 'road safety facility installation and management guidelines' were established in November, 2012.

Due to the lack of performance standards for such unprotected protective fences, it is a reality that the vehicle frequently breaks through the steel fence and guardrail and the passenger is injured.

In order to solve the problem of the unprotected protection fence described above, when the performance is verified through the collision test, it is about 3 trillion KRW nationwide, and Chungcheong region about 400 billion KRW (replacement cost: 150 million KRW) It is known that a huge budget is needed.

Therefore, in order to improve the performance of the existing guard fence efficiently by using a limited budget, economical improvement techniques are needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, a description will be given of a method for reinforcing a vehicle security fence according to the present invention and an embodiment of a reinforced vehicle security fence.

The vehicle protection fence prevents the vehicle departing from the normal traveling route during traveling from being out of the way, the opposite lane or the sidewalk, and at the same time reducing the damage of the occupant and the damage of the vehicle to a minimum and returning the vehicle to the normal traveling direction It is a facility to install.

FIG. 1 is an exemplary view showing a conventional conventional guardrail type protective fence,

As shown in the drawing, a general guardrail-type guard fence includes a plurality of struts 10 fixed at regular intervals and fixed in the ground vertically, and a guard rail 20 fixed to the struts 10, As a fence, guard rails (20) are fixed to the rear surface of the guard rails (20) by guard rails fixing means that are connected by fitting adjacent ends of the guard rails (20) 10 and the guard rail 20 are fixed to each other.

However, in general, if a guard fence having only a form of guard rail combined with a support and a support structure is not yet verified as a standard fence before the latest performance evaluation standard is established, It is possible that frequent crashes such as a vehicle crash that breaks and breaks the passenger.

Therefore, the present invention provides the reinforced cable 30 and the energy dissipating device for the purpose of improving the performance of the conventional vehicle protection fence without applying the latest standard through the reinforcement of the general protection fence for carrying out the above- It is intended to provide a protective fence that further enhances the performance of the fence or conforms to a more robust design specification.

2 is a flowchart illustrating a method for reinforcing a vehicle security fence according to an embodiment of the present invention. As shown in the figure, the method of reinforcing the guard fence includes the step of replacing the nut (S100), the step of connecting the cable (S200), the step of installing the energy dissipating means (S300), and the step of fixing the cable (S400).

The step of replacing an eye nut (S100) is a step of replacing a fixing nut 120, which is a guard rail connecting means, with an eye nut 40 of the present invention in an existing security fence, The nut 40 is applied.

FIG. 3 is a rear view of FIG. 1 and illustrates an example of replacing a nut coupling on a rear surface of a guard rail according to an embodiment of the present invention with an eye nut. In the eye nut replacing step S100, When replacing the fixing nut 120 with the eye nut 40, only the conventional fixing nut 120 selected according to the arrangement and the number of cables can be replaced with the eye nut 40 of the present invention.

FIG. 3 shows an example of an eye nut to be replaced when connecting two lines of cables at the upper and lower ends. The eye nut 40 to be replaced at the opposite side of the support 10 is not shown.

The cable connecting step S200 is a step of attaching the reinforcing cable 30 to the in-nuts 40 to be replaced in the in-nut replacing step S100, And the other one row of cables is inserted into the lower-side eye nut 40 by inserting. The cable 30 is a reinforcement wire formed by twisting a plurality of strands of steel wire.

In addition, in the cable connection step S200, an energy dissipation means installation step S300 is performed.

The energy dissipating means installing step S300 may include installing the spring device 50 or the steel pipe device 60, which is the energy dissipating device of the present invention, between the eye nuts 40 that have been replaced in the eye nut replacing step S100 .

FIG. 4A is an exploded view and a fixing perspective view showing a spring device attachment method in a method for reinforcing a vehicle security fence according to an embodiment of the present invention, and FIG. 4B is a sectional view of a cable fixation by a wedge according to the energy dissipating device coupling method of FIG. , And Fig. 4C is a plan view of Fig. 4A.

Fig. 4D is a plan view showing the state of engagement of the energy dissipating device by the support end cap in the steel pipe device according to the energy dissipating device joining method, Fig. 4E is a top view to be.

Accordingly, in the energy dissipating means installing step (S300), the energy dissipating device is coupled to the cable (30) through an energy dissipating device coupling method.

The energy dissipating device joining method uses a method of joining the wedge 80 and the wedge grip ring 90 and the support ring 100 to the spring device 50 or the steel pipe device 60 as the energy dissipating device .

The wedge 80 is a cable fixing socket capable of fixing the cable 30 from the inside to the outside, and fitting the energy dissipating device into the outside.

Therefore, the inner side of the wedge 80 is formed so as to increase the fixing force of the cable 30 in a geometrical shape, and the outer side has a small diameter at one end so that the energy dissipating device can be engaged with the other, And a circumferential groove around the wedge 80 that is worn on the outer circumferential surface.

The wedge grip ring 90 is inserted into the groove around the wedge 80 on the outer circumferential surface of the wedge 80 while the cable 30 is connected to the wedge 80, It is a cable fixation ring that strongly ties up.

Therefore, the cable is fixed through the wedge 80 and the wedge grip ring 90.

The spring device 50 or the steel pipe device 60 which is the energy dissipating device can be inserted and connected to the cable 30 fixed by the wedge 80 through one end of the wedge 80. [ At this time, the energy dissipating device is fixed to one end of the wedge 80 by being inserted into the wedge 80.

Then, the support ring 100 is fitted to the other end of the energy dissipating device.

Wherein the support ring (100) has a through hole having an inner diameter larger than the other end of the energy dissipating device and a through hole penetrating the cable (30), and the energy dissipating device coupled with the wedge (80) And a cushion stopper which serves as a cushioning and buffering function.

Therefore, when the support ring 100 coupled with the energy dissipating device has an end larger than the diameter of the eye nut 40 so that the cable 30 is pulled by a tensile force due to a vehicle collision, The repulsion causes compression deformation of the spring device 50, which is the energy dissipating device, or buckling deformation of the steel pipe device 60.

As described above, the energy dissipating means mounting step S300 is performed through the energy dissipating device joining method. The energy dissipating device joining method includes a wedge joining step S310, a wedge grip ring joining step S320, The device connection step S330, and the support ring connection step S340.

The wedge joining step S310 is a step of penetrating the cable 30 to the wedge 80 for fixing the cable 30 and the wedge grip ring joining step S320 is a step for joining the cable 30 to the wedge 80 And reinforcing the compressive force to finally fix the cable 30.

The energy dissipating device connecting step S330 is a step of fitting the spring device 50 or the steel pipe device 60 as the energy dissipating device to the cable 30 fixed by the wedge 80, The supporting ring coupling step S340 is a step of connecting the support ring 100 to the other end of the energy dissipating device connected to the wedge 80. [

Also, the support end cap 110 may be used in place of the support ring 100 used in the support ring assembling step S340.

The support end cap 110 has a through connecting cylinder having an inner diameter smaller than that of the other end of the energy dissipating device and a cap having a large diameter so that the energy dissipating device can act as a hook and buffer by the eye nut 40 It is a cap.

The energy dissipating device coupling method includes fixing the cable 30 at an intermediate portion of the energy dissipating device by the wedge 80, penetrating the energy dissipating device in both directions and connecting the support ring 100 Or the support end cap 110 may be combined to provide the energy dissipating device.

Therefore, the energy dissipating device coupled through the energy dissipating device coupling method is configured such that the cable 30 is fixed to the wedge 80 by the wedge 80 and the energy dissipating device Wherein the energy dissipating device moves in a direction in which the cable pulls when the tension of the cable is generated and the support ring 100 or the support end cap 110 is caught by the eye nut 40, The energy dissipating device is operated in a unidirectional manner by locating the wedge 80 at one end or fixing the wedge at the center, So that the energy dissipating device can be coupled to operate in both directions. Fig. 10 shows an exemplary view showing a bi-directional coupling state of the energy dissipating device by the support ring.

In the cable fixing step S400, an end of the cable 30 including the energy dissipating device connected between the eye nuts 40 is connected to the lower end of the outermost support 10, and a fixing means, such as a turnbuckle 70, The tension of the cable 30 is adjusted and firmly fixed.

5 is an exemplary view showing a reinforced protective fence using a method for reinforcing a vehicle security fence according to an embodiment of the present invention, and FIG. 6 is a side view of FIG. 5. FIG.

As shown in FIGS. 5 and 6, the reinforced vehicle protection fence of the present invention further includes a cable 30, a cable fixing means, and an energy dissipating device to reinforce a conventional guardrail-type protection fence .

The cable fixing means of the present invention can replace the fixing nut 120 which is the guard rail fixing means used for fastening the screws at both sides of the connecting end of the conventional guard rail 20 with the eye nut 40, And fixing the cable 30 to the cable.

The cable fixing means includes a turnbuckle 70 connected to the end of the cable 30 by a lower end of the outermost support 10.

The eye nut 40 as the cable fixing means is in the form of a round ring and has a plurality of cables in the form of one or more rows on the side surface of the guard rail 20 while passing the cable 30 in the form of a wire into the eye nut 40. [ As shown in FIG.

The eye nut 40 as the cable fixing means of the present invention is mounted on both sides of the guard rail 20 in the conventional guard rail 20 in the form of a conventional guard rail 20 and is used as a conventional connection fixing nut 120 ). Therefore, the cable fixing means can be directly used by replacing the existing connection nut with the eye nut 40 of the present invention. Therefore, it is possible to efficiently improve the performance of the existing guard fence by using a limited budget without replacing the existing guard rail type guard fence.

In addition, the present invention provides a method of reinforcing the shock absorbing performance of a vehicle through the energy dissipating device, wherein the energy dissipation is a phenomenon in which the impact energy generated when the vehicle is impacted is absorbed or dispersed and dispersed , And the energy dissipating device is coupled to the cable (30) by the energy dissipating device coupling method to further reinforce shock absorption.

FIG. 7A is a front view showing a spring-type energy dissipating device according to an embodiment of the present invention, and FIG. 7B is a plan view of FIG. 7A, showing an example of an energy dissipating device using a compression-deforming spring device 50. In Fig. 7A, the support 10 is not shown.

The spring device 50 is positioned between the wedge 80 and the wedge grip ring 90 between the eye nut 40 which is the cable securing means fitted to both sides of the guard rail 20 connector in the protective fence Connected to the support ring (100) and coupled to the support ring (100) by the energy dissipating device coupling method to generate a tensile force of the cable when the cable is pulled in the direction of the tensile force, The energy absorption of the cable 30 is further reinforced while the elastic member 100 is caught by the eye nut 40 and the eye nut 40 and the spring device 50 are repelled by each other to cause compressive deformation of the spring .

In addition, the steel pipe apparatus 60 is connected to a rod-shaped steel pipe between the eye nuts 40 to perform energy dissipation using the buckling deformation of the steel pipe. Like the spring device 50, 40 and the wedge grip ring 90 and the support ring 100 between the wedge 80 and the energy dissipating device coupling method between the wedge 80 and the wedge grip ring 90 to generate tensile force in the direction of the tensile force The support ring 100 connected to the steel pipe apparatus 60 is caught by the eye nut 40 when the cable is pulled and the eye nut 40 and the steel pipe apparatus 60 are repelled each other, So that energy can be dissipated to further reinforce the energy absorption of the cable 30 while deformation occurs.

The buckling deformation refers to a phenomenon in which the compression member is bent or deformed when a compression force acts on the compression member. This is a concept of a function similar to compression deformation of the spring device 50.

As shown in FIG. 8, the other one of the fixing means of the cable 30 according to the present invention is a cable for fixing the turn- And a turnbuckle 70 connected by a lower end of the cable 10 to adjust the tension of the cable 30 and fix the cable 30.

The turnbuckle 70 is a screw that forms the tension of a wire or a wire by a screw, and when the cable 30 is installed or when a wire is tightened, the screw has a screw rod. One screw is a right screw, the other screw is a left screw . When a part with a female thread, that is, a nut, is rotated, the two male threads approach each other and the rotation is reversed. Therefore, when a cable such as a rope or a wire is pulled tight, the turnbuckle 70 is inserted in the middle, and it can be pulled up by turning it.

FIG. 9A is a view showing an example of a spring-type energy dissipating device according to an embodiment of the present invention before and after a vehicle collision. FIG. 9B is a graph showing an energy dissipating device of a steel pipe type according to an embodiment of the present invention, Fig.

According to the above description and the drawings, the impact force generated when the vehicle collides with the reinforced vehicle protection fence according to the present invention is firstly shock-absorbed by the guard rail 20, and furthermore, the reinforcing cable 30, But if the vehicle impact force is stronger, a tensile force is generated in which the cable 30 is stretched in the vehicle collision direction. The support ring 100 or the support end cap 110 coupled with the spring device 50, which is the energy dissipating device coupled with the energy dissipating device, may be engaged with the eye nut 40, (50).

Therefore, the impact energy is absorbed by the tension device of the spring device 50, which is the energy dissipating device, and the impact energy is absorbed by the cable fixing device of the turnbuckle 70 at the outermost side of the strut, And to provide an improved vehicle shock absorbing protective fence which is capable of effectively absorbing an impact force caused by a vehicle collision with a view to reducing the damage of the occupant and the breakage of the vehicle to a minimum and returning the vehicle to the normal traveling direction. The energy can be absorbed by the buckling deformation of the steel pipe device 60 in the same procedure even when the vehicle collides with the steel pipe device 60, which is a steel pipe type energy dissipating device.
