≪ Example 1 >

As shown in FIGS. 1 to 3, the protective fence having the buffer type handrail according to the present embodiment comprises: a foundation base 10 fixed to the ground at a predetermined distance from each other; A strut (20) which is respectively erected on the foundation base (10); And upper and lower hand rails 30 and 40 which are installed vertically between the supports 20 to block the space between the supports 20 and in which the upper handrail 30 extends from the support 20 towards the road And the lower handrail 40 is installed to be elastically movable through the lower side elastic connection 50 while protruding from the support 20 toward the road.

The foundation base 10 is a plate material having an area larger than that of the column 20 and is fixed to the column 20 through welding or the like and is fixed to the floor or concrete base through anchoring or is made elastic .

The column 20 is fixedly installed on the foundation base 10 by welding or the like. For example, the column 20 may be a circular pipe having a hollow inside and a cap may be assembled on the upper part.

As shown in FIGS. 1 and 4, the upper handrail 30 is fixed (weldable) to the fastener 31 (bolt and nut) while the left and right sides of the upper handrail 30 are in close contact with the adjacent support pillars 20, The handrail 30 is firmly fixed to the support 20 through close contact and fastening, thereby generating a bending force against the collision of the vehicle, thereby preventing the vehicle from being pushed.

Preferably, the upper handrail 30 has a structure of a frame formed by the upper and lower horizontal portions 32, 33 and the left and right vertical portions 34, 35, and one or more horizontal legs 36 are applied to reinforce the strength. It is also possible that the various shapes of the shapes 37, such as the circular shape, the polygonal shape, the flower shape, etc., are formed together.

The fastening holes 31 are formed on the right side vertical portion 35 of the upper handrail 30 on the left side and the support 20 and the upper side handrail 30 on the right side of the left hand rail 30, The vertical portions 34 on the left side of the hand rail 30 are assembled together by a fastening tool 31. 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 present invention is also capable of making the indication of the pattern as the main purpose since 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 may be a circular or square pipe having an internal hollow structure and may be of various structures, while being elastically supported by the lower side elastic connection 50 to protrude forward of the support 20.

As shown in FIGS. 5, 6 and 7, the lower side elastic coupling 50 includes a central column fixing part 51 having a substantially semicircle shape surrounding the periphery of the column 20, The leaf spring is composed of wing portions (52, 53) extended from both sides of the wing portion (52, 53) and joined to the neighboring lower handrail (40) 55 are formed in the wing portions 52 and 53 for elastic behavior and are formed in the wing portions 52 and 53 through the upper and lower hand rails 40 and 40, (Which may be a bolt and a nut) 56 are fastened to the fastening holes of the upper handrail 40 and the lower handrail 40. The lower side elastic connector 50 can be made of various materials such as spring steel and synthetic resin.

When the impact is applied from the outside, the lower side elastic connection 50 having the above-described structure is pushed by the external force to the wing portions 52 and 53 with the pillar holding portion 51 fixed to the pillar 20 as a fulcrum, Thereby guiding the elastic behavior of the rail 40.

The lower elastic link 50 is fixed to the opposite side surface of the support 20 while the wing portions 52 and 53 are fixed to the outer surface of the lower handrail 40 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 posts 20 in order to reduce the damage of the lower side elastic connection 50 while being elastically moved by the lower side elastic connection 50 The diameter of the column 20 and the size of the elastic connection 50 on the lower side are adjusted.

Since the lower side 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 lower side elastic connection 50 has an outer diameter smaller than that of the elongated holes 54 and 55 of the lower side elastic connection 50, Thereby enabling the elastic behavior of the lower handrail 40 to be performed.

The construction of the guard fence having the buffer type handrail according to the present embodiment is carried out in the order of installation of the column 20-installation of the upper handrail 30 and the lower handrail 40, The foundation base 10 is installed through a plurality of anchors on a base portion (such as a concrete foundation portion) constructed on the ground or the ground and the lower handrail 40 is installed between the supports 20 through the lower side elastic connection , And the upper handrail (30) is installed on the support (20).

The lower handrail 40 is installed to allow elastic behavior through the lower side elastic connection 50. When the vehicle collides with the lower handrail 40, ) First clash with the vehicle.

The impact applied to the lower handrail 40 is transferred to the lower side elastic connection 50 and the lower side elastic connection 50 is elastically deformed by the impact energy transferred from the lower handrail 40, Since the lower handrail 40 and the lower side elastic connection port 50 are connected to each other through the elongated holes 54 and 55, As the guide pin 56 moves along the elongated holes 54 and 55 of the lower elastic link 50, it absorbs the impact as much as it moves, thereby reducing damage to the vehicle and the fence.

Even if the vehicle collides with the fence, the lower handrail 40 and the lower side elastic connector 50 absorb a lot of impact energy, and the vehicle can be turned from the fence through this process. Therefore, (20) is not directly impacted. Even if the upper handrail 40 is directly impacted, the upper handrail 30 exerts a supporting force on the support 20 as a support base to prevent the vehicle from being pushed. At this time, the lower side elastic connection 50 Thereby supporting the lower handrail 40, thereby preventing damage to the vehicle and delaying the vehicle's pivoting.

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 fence through the buffering step.

≪ Example 2 >

8 to 10, a protective fence having a buffer type handrail according to the present embodiment includes a base base 10, pillars 20 standing upright on the base base 10, And a lower handrail 40 fixed to the support 20 by a lower side elastic connection 70. The base handrail 30 and the lower handrail 40 are fixed to the base 20 and the base 20, The support 20 is the same as the first embodiment described above and differs from the first embodiment in that the upper handrail 30 is provided on the support 20 via the upper side elastic connection 60. The lower handrail 40 Is protruded through the front side (road side) of the support pillars 20 through the lower side elastic connection port 70.

The upper handrail 30 is provided between the supports 20 as a pipe having an outer diameter smaller than that of the column 20 (an empty structure as a whole for assembling the upper side elastic connection 60 or a space on both sides in the longitudinal direction) And are arranged in a line with the columns 20 so as not to protrude from the column 20 and to be elastically deformable in the column 20 through the upper side elastic connection 60, As shown in FIG.

[ The movable guide pin 67 (which may be a bolt and a nut) is fastened to the elongated holes 64 and 65 of the guide pin 67. [ The movement guide pin 67 has an outer diameter smaller than the width of the long holes 64 and 65 so that the elastic movement of the upper side elastic coupling 60 can be performed.

That is, when the vehicle collides with the upper handrail 30, the motion guide pin 67 moves along the elongated holes 64 and 65 of the upper side elastic coupling 60, while the upper handrail 30 is pushed, And then the upper side elastic connector 60 is elastically deformed to buffer the impact energy.

The upper side elastic coupling 60 is 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 rigidly 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, The spring steel and the synthetic resin are used as materials. The cushioning material 68 is applicable not only to the upper side elastic connection but also to the lower side elastic connection.

Of course, it is also possible that only one of the upper side elastic connectors 60 is applied as shown in FIG. One upper side elastic connection 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.

13, the upper side elastic connector 60 can be applied to the outer side of the pillar fixing portion 61 (the reinforcing piece 69 can also be applied to the case of Fig. 5) Do. 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.

That is, in the present invention, only the lower handrail 40 protrudes from the column 20, both the lower handrail 40 and the upper handrail 30 protrude from the column 20, the lower handrail 40 Both the upper handrail 30 and the lower handrail 40 do not protrude from the support 20 and do not protrude from the support 20 All that is possible is to be included].

In the first embodiment, the lower handrail 40 is disposed between the support posts 20 and protrudes forward from the support posts 20. As shown in FIGS. 14 and 15, 40 are provided in front of the support pillars 20, and a lower side elastic connector 70 corresponding to this structure is used.

The lower elastic link 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 support 20 is a lower handrail 40 And is fixed together with the lower handrail 40 and the support 20 through the fastening hole 71 in the state where the opposite side edge portion abuts the support 20.

The lower side elastic connector 70 is buffered in size and structure to form 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 lower side 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 lower side elastic connecting piece 70. The center portion of the elastic reinforcing piece 72 contacts the outer peripheral surface of the lower handrail 40, At this time, a space is formed between the lower side elastic connector 70 and the lower side elastic connector 70. At this time, the lower side elastic connection 70 supports the lower handrail 40 by the elastic reinforcing piece 72, and the elastic reinforcing piece 72 is bent in the lower hand direction due to the difference in curvature with the lower side elastic connection 70, Even if the rail 40 is pushed, a space is formed with the lower side elastic connector 70.

When the vehicle collides with the lower handrail 40, the lower handrail 40 is contracted while the lower side elastic connector 70 is in contact with the lower handrail 40, Buffering action occurs.

As described above, the base base 10 can be installed so as to be elastically movable on the base portion (ground surface or the like) through the base elastic means. As shown in FIGS. 16 to 18, the base elastic means 100, The pillar 20 is installed in a pivot form. When the external force is applied, the pillar 20 is inclined while absorbing external force, and when the external force is extinguished, the pillar 20 is restored to its original state.

The base elastic means 100 is fixed to the ground via an anchor bolt buried in the ground and is supported in contact with a guide plate 21 formed at an upper portion of the lower portion of the lower end of the support 20 to be inclined upward toward the center The base support member 110 is deformed from the base base 10 and one end portion is pivotally coupled to the base support member 110 and the other end is positioned inside the support 20, And a resilient member 130 provided inside the lower end of the support 20 such that the support shaft 120 and the support 20 are elastically supported by the support shaft 120. [

The base support member 110 has a base plate 111 fixed to the ground and a seating plate 112 bonded to the base plate 111 to guide the support 20. [

The base plate 111 is coupled to the anchor bolt 115 through a nut and has an installation through hole 113 for installing the elastic member 130 at the center.

In addition, the seating plate 112 is coupled to the upper surface of the base plate 111.

The seating plate 112 is bonded to the base plate 111 through a bonding method such as welding, bolt, rivet, or the like.

The seating plate 112 is joined to the upper surface of the base plate 111 so that the supporting shaft member 120 is penetrated and supported and the guide plate 21 of the supporting column 20 is held in contact with the outer surface.

The seating plate 112 has a semi-circular shape so that the guide plate 21 can be easily and smoothly guided in contact with the guide plate 21. At this time, the seating plate 112 protrudes upward and has a semicircular shape, and a flow hole 114 is formed at the center so that the supporting shaft member 120 is inclined together with the movement of the support 20.

The supporting shaft member 120 has a supporting shaft 121 whose lower end is connected to the seating plate 112 and the other end is located inside the supporting column 20 and the supporting shaft 121 is connected to the elastic member 130 And anti-release plates 122 and 123 respectively coupled to upper and lower ends of the support shaft 121 so as to be resiliently supported.

The support shaft 121 is fastened to the upper and lower fixing nut members 124 and 125 so that the separation prevention plates 122 and 123 are stably engaged. Accordingly, the support shaft 121 is formed with threads on the outer circumferential surface (upper and lower, or the entire surface) so that the fixing nut members 124 and 125 can be fastened. The fixing nut members 124 and 125 adjust the elastic force of the elastic member 130 according to the screwing position. When the support shaft 121 is a bolt having a head, the fixing nut member is fastened only to one side of the upper or lower side.

The separation prevention plates 122 and 123 are respectively coupled to the upper and lower ends of the support shaft 121 through the fixing nut members 124 and 125 to prevent the support shaft 121 from being separated from the seating plate 112 and the elastic member 130 do.

Further, the separation preventing plates 122 and 123 are formed in a semicircular shape so that they can be smoothly raised and restored after the struts 20 are inclined.

The semicircular separation prevention plate 122.123 reduces the contact area between the seating plate 112 and the elastic member 130 so that the support 20 can be tilted and raised smoothly.

A through hole is formed in the center of the moving support plate 131 so that the support shaft 121 penetrates through the through hole and a central portion of the upper side release prevention plate 122 is seated. The movement support plate 131 is smoothly moved to the center of the through hole due to the elasticity of the spring member 133 even if the semicircular release prevention plate 122 is detached from the through hole due to the inclination of the support 20. [ . That is, the movable support plate 131 paired with the escape prevention plate 122 leads to a more smooth standing of the support post 20.

The fixed support plate 132 is coupled to the post 20 to support the spring member 133. The outer surface of the fixed support plate 132 is joined to the inner surface of the column 20 and the through hole is formed at the center so that the support shaft 121 passes through the through hole.

The upper end of the spring member 133 is in contact with the lower surface of the movable support plate 131 and the lower end thereof is in contact with the upper surface of the fixed support plate 132. The spring member 133 elastically supports the moving support plate 131 in the upward direction so that the column 20, which has been inclined due to the impact, stands upright.
