The fastening tool 31 has one or more stages As shown in Fig. Of course, when the upper handrail 30 is assembled to only one side of the support 20, the support 20 and the vertical portion 34 or 35 of the upper handrail 30 are assembled by the fastening member 31.

The upper handrail 30 is preferably a circular hollow pipe with hollow interior.

The upper handrail 30 receives less collision than the lower handrail 40 and is not subjected to a direct collision.

The lower handrail 40 is a rectangular frame structure formed by upper and lower horizontal portions and right and left vertical portions. It is preferable that one or more horizontal and an inclined reinforcing bars are provided for reinforcement, and the lower handrail 40 is installed at a position where the bumpers of the vehicle collide. The lower handrail 40 is not limited to the one shown in the drawings, and various structures capable of displaying a pattern together with strength reinforcement are possible.

The lower handrail 40 is installed to resiliently move while protruding toward the front side of the strut 20 by means of the elastic connection 50. The hollow handrail 40 is preferably a circular or square pipe having hollow interior and various structures are possible.

7 and 8, the elastic connector 50 includes a central column fixing portion 51 having a substantially semicircle shape surrounding the periphery of the column 20, and a pair of right and left column fixing portions 51 The leaf spring is composed of blade portions 52 and 53 extending in the left and right direction and assembled to the neighboring lower handrail 40. The leaf spring is fixed to the fastener 54 in a state in which the post fastener 51 covers the post 20, And longitudinally elongated holes 54 and 55 for elastic behavior are formed in the wing portions 52 and 53 respectively so that the fastening portions 54 and 55 and the lower handrail 40 (Together with a bolt and nut) 56 is fastened to the ball so that it is assembled with the lower handrail 40.

The elastic connector 50 is fixed to the outer surface of the lower handrail 40 on the opposite side of the road while the pillar fixing portions 51 are fixed on the opposite side of the pillar 20, So that the lower handrail 40 protrudes more toward the road than the post 20.

The lower handrail 40 is configured such that only a part of the lower handrail 40 protrudes from the support 20 in order to reduce the damage of the elastic connector 50 while the elastic handrail 50 elastically moves. The size of the elastic connector 50 is controlled.

Since the elastic connector 50 is installed on the opposite side of the road, it does not cause direct collision with the vehicle and therefore does not cause breakage.

The movement guide pin 56 for assembling the lower handrail 40 and the elastic connector 50 has an outer diameter smaller than that of the elongated holes 54 and 55 of the elastic connector 50 and moves along the long holes 54 and 55, So that the elastic behavior of the handrail 40 is made possible.

The construction of the guard fence using the elastic pillars according to the present embodiment is carried out in the order of installation of the pillars 20-the upper handrail 30 and the lower handrail 40, The lower handrail 40 is installed between the pillars 20 through the elastic connection port and the lower handrail 40 is provided between the upper handrail 40 and the lower handrail 40. [ (30) is provided on the support (20).

According to the present embodiment, the lower handrail 40 is installed to be elastically movable through the elastic coupling 50, and when the vehicle collides with the lower handrail 40, It collides with the vehicle.

The impact applied to the lower handrail 40 is transferred to the elastic connector 50. The elastic connector 50 elastically deforms due to impact energy transferred from the lower handrail 40 to absorb impact energy, Since the lower handrail 40 and the elastic coupling 50 are connected to each other through the elongated holes 54 and 55, the movement guide pin 56 fixed to the lower handrail 40 can be prevented from being damaged, Absorbs the impact as much as it moves along the elongated holes 54 and 55 of the elastic connector 50, thereby reducing the damage of the vehicle and the protective fence.

Even if the vehicle collides with the protective fence, the lower handrail 40 and the elastic connector 50 absorb a lot of impact energy, and the vehicle can be turned from the protective fence through the process. Therefore, (20) is not directly impacted. Even when the upper handrail 40 receives a direct impact, the upper handrail 30 exerts a supporting force on the support 20 as a support base to prevent the vehicle from being thrown. At this time, Thereby supporting the rail 40, thereby preventing the vehicle from being damaged and delaying the jolt of the vehicle.

That is, since the lower handrail 40 protrudes more toward the road than the support 20, the lower handrail 40 is subjected to a first collision and the upper handrail 30 is subjected to a second collision, It is effective to reduce the damage of the vehicle and the protection fence through the buffering step.

9 and 10, the elastic coupling 60 of the upper handrail 30 includes a column fixing part 61 which is fixed to the column 20 while surrounding the periphery of the column 20, (62, 63) extending in the direction of the upper handrail (30) from both left and right sides of the upper handrail (30) and having elongated slots (64, 65) And is installed symmetrically with the support 20 on the opposite side of the road.

The fixing of the upper handrail 30 and the elastic connector 60 can be performed by fixing the upper handrail 30 and the wings 62 and 63 in a state where the wings 62 and 63 are inserted into the upper handrail 30. [ (Which may be a bolt and a nut) are fastened to the guide pins 64 and 65 to be assembled. The movement guide pin 67 has an outer diameter smaller than that of the long holes 64 and 65 so that the elastic connection 60 can be elastically deformed.

That is, when the vehicle collides with the upper handrail 30, the movement guide pin 67 moves along the elongated holes 64 and 65 of the elastic coupling 60 while the upper handrail 40 pushes the impact energy, Then, the elastic connector 60 is elastically deformed to buffer the impact energy.

The elastic connectors 60 are assembled symmetrically on both sides of the column 20 to exert a great elastic force to maximize the cushioning effect even though the upper handrail 30 is firmly installed.

It is also possible that the cushioning material 68 is applied together with the behavior guide pin 67.

The cushioning material 68 is in the form of a cylinder or a coil and is coupled to the periphery of the motion guide pin 67, that is, applied at two positions between the wing portions 62, 63 and the upper handrail 30, .

Of course, it is also possible that only one elastic connector 60 is applied. One elastic connector 60 is provided on the opposite side of the road so that the upper handrail 30 can be elastically moved by a collision of the vehicle.

As shown in Fig. 11, it is also possible for the elastic connector 60 to be applied to the outer side of the pillar fixing portion 61, which is also applicable to the method of Fig. 7. The reinforcing piece 69 is a curved plate having a curvature smaller than that of the holding portion 61. The left and right sides of the reinforcing piece 69 are supported between the holding portion 61 and the wings 62, 63).

The supporting piece 69 can be applied to more than two pieces, and as the distance from the supporting piece 20 is gradually reduced and the length is shortened, the supporting position is changed, And a chain supporting force is ensured, thereby minimizing the jamming of the upper handrail 30.

The lower handrail 40 is not limited to being projected from the column 20 but may also be arranged in line with the upper handrail 30 and not protruding from the column 20.

12 and 13, the present embodiment is different from the first embodiment in that the lower handrail 40 is disposed between the pillars 20 and protrudes forward from the pillars 20, 40 are provided in front of the support posts 20, and the elastic connectors 70 corresponding to these structures are used.

The elastic connector 70 is a circular structure having an inner diameter that surrounds the lower handrail 40 and has an opening at one side of the lower handrail 40. The opening between the lower handrail 40 and the stanchion 20 surrounds the lower handrail 40, And is fixed together with the lower handrail 40 and the support 20 through the fastening hole 71 with the periphery thereof abutting against the support 20.

The elastic connector 70 can be buffered with a size and structure that forms a buffer space with the lower handrail 31.

In addition, an elastic reinforcing piece 72 for increasing the supporting force of the lower handrail 40 may be applied to the elastic connector 70.

The elastic reinforcing piece 72 may be a curved line or a straight plate having a curvature larger than that of the elastic connecting piece 70. The center portion touches the outer peripheral surface of the lower handrail 40 while the upper and lower ends thereof are supported on the inner surface of the elastic connecting piece 70, At this time, a space is formed between the elastic connector (70). At this time, the elastic connector 70 supports the lower handrail 40 by the elastic reinforcing piece 72, and the elastic reinforcing piece 72 is connected to the lower handrail 40 due to the difference in curvature with the elastic connector 70. [ Thereby forming a space with the elastic connector 70.

When the vehicle collides with the lower handrail 40, the elastic connecting port 70 is contracted by the elastic reinforcing piece 72 while the lower handrail 40 is contracted, It happens.
