Description

다기능 탄성 볼라드{Multifunctional elastic bollard}Multifunctional elastic bollard {Multifunctional elastic bollard}

본 발명은 다기능 탄성 볼라드에 관한 것으로서, 더욱 구체적으로는 보행자의 안전과 통행권 등을 보장하고 차량 진입을 방지하며 차량과의 충돌시의 충격을 흡수할 수 있는 완충 작용을 하고, 차량의 진입 등을 허용하여야 하는 경우 해체 및 재설치 등이 용이할 수 있도록 함과 동시에 차량 충격 등으로 훼손된 경우 유지 보수가 용이한 다기능 탄성 볼라드에 관한 것이다.The present invention relates to a multifunctional elastic bollard, and more specifically, to ensure the safety and pass of the pedestrians, to prevent the entry of the vehicle, and to act as a buffer to absorb the impact when the collision with the vehicle, the entry of the vehicle, etc. The present invention relates to a multifunctional elastic bollard that is easy to be dismantled and reinstalled when it should be allowed, and at the same time easy to maintain when damaged by a vehicle shock.

일반적으로 볼라드(bollard)는 차도를 운행하는 차량이 보도를 향하여 무분별하게 난입하는 것을 방지하여 보행자를 보호하기 위하여 보도와 차도 사이에 설치되거나, 또는 특정 구간으로의 차량 진입을 제어하여 차량의 진행방향 등을 안내하는 안내표지판으로 활용될 수 있도록 특정 도로의 진입 차도에 설치된다.In general, a bollard is installed between a sidewalk and a roadway to protect a pedestrian by preventing a vehicle driving on a roadside indiscriminately from entering a sidewalk, or by controlling a vehicle's entry into a specific section to control a vehicle's direction of travel. It is installed on the entrance road of a specific road so that it can be used as a guide sign for guiding lights.

종래의 볼라드는 석재, 콘크리트, 또는 금속재질을 일체로 형성하여 대략 원형 또는 사각기둥 형태의 포스트를 지면에 매설한 후 모르타르 시공 또는 앵커 등의 체결 수단 등을 통하여 지면과 고정된다. 그러나 이와 같은 종래의 볼라드는 보행자의 빈번한 안전사고와 안전상해를 유발시켰고 디자인화 되어가는 도시경관에 오히려 흉물로 지적 되어왔다.Conventional bollard is formed of a stone, concrete, or metal material integrally embedded in the ground of the post of approximately round or square pillar shape is fixed to the ground through a fastening means such as mortar construction or anchor. However, such a conventional bollard has caused frequent safety accidents and safety injuries of pedestrians, and has been pointed out as a horror in the urban landscape being designed.

이에, 최근에는 보행자와의 충돌과 같은 외부 충격을 흡수하여 보행자를 보호함과 동시에 차량 충돌의 훼손을 억제할 수 있는 볼라드가 또한 널리 활용되고 있다.In recent years, bollards are also widely used to absorb external shocks such as collisions with pedestrians to protect pedestrians and to prevent damage to vehicle collisions.

또한 종래의 고정타입형의 볼라드는 화재 또는 천재지변 등에 의한 비상사태가 발생할 경우, 지면에 매립되어 있는 하부베이스의 해체가 용이하지 못하여 사고나 사태 등이 발생된 지역으로의 작업차량 투입이 어렵게 되어 사고나 사태등의 진압이 지연되는 문제점이 지적되고 있다.In addition, the conventional fixed-type bollard is difficult to disassemble the lower base embedded in the ground in case of emergency due to fire or natural disaster, it is difficult to put the working vehicle into the area where an accident or situation occurred. The problem that the suppression of an accident or a situation is delayed is pointed out.

The first pipe 10 on which the fixing disc 21 and the outer shell 11 are coated by the fixing bolt 24 and the fixing nut 23 is fixed to the fixing nut 23 by screwing. Configure detachably.

미설명부호 15a는 탄성돌기이다.Reference numeral 15a denotes an elastic protrusion.

이상과 같은 구성의 본 발명에 따른 볼라드의 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the bollard according to the invention of the above configuration as follows.

먼저 본 발명의 볼라드(1)를 설치할 때는 볼라드(1)를 설치할 위치에 제2파이프(20)를 콘크리트 타설에 의해 매립 고정하는 것이다.First, when installing the bollard (1) of the present invention is to embed the second pipe (20) in the position to install the bollard (1) by embedding the concrete.

콘크리트 타설시 고정용 원판(21)을 고정할 앵커볼트(22a)를 같이 매립하는 것이다.When anchoring the concrete is to bury the anchor bolt (22a) to fix the fixing plate (21).

상기 매립된 제2파이프(20)의 내측에 외피(11)가 입혀진 제1파이프(10)를 내입시키고 제2파이프(20)의 상단에 고정용 원판(21)을 앵커볼트너트(22a)(22b)로 고정한 후 제2파이프(20)의 내측에 내입된 외피(11)가 입혀진 제1파이프(10)의 손잡이(19)를 잡고 외피(11)가 입혀진 제1파이프(10)를 인상시킨 후 고정용 원판(21)과 완충부재(14) 및 제2원판(15)을 고정볼트(24)와 고정너트(23)로 나사결합하면 볼라드(1)가 설치 완성되는 것이다.The first pipe 10 having the outer shell 11 coated on the inner side of the buried second pipe 20 is embedded therein, and the fixing bolt 21 is fixed to the upper end of the second pipe 20 by anchor bolt nuts 22a ( 22b) and hold the handle 19 of the first pipe 10 coated with the outer shell 11 embedded inside the second pipe 20 to raise the first pipe 10 coated with the outer shell 11. After screwing the fixing disk 21 and the buffer member 14 and the second disk 15 with the fixing bolt 24 and the fixing nut 23 is the bollard (1) is completed installation.

설치 완료된 볼라드(1)에 차량 등에 의해 충격이 가해지면 완충부재(14)의 탄성과 제1원판(12)의 유동공(12a)에 의해 도 4의 도시와 같이 볼트(16)가 기울려지면서 제1파이프(10)가 일측으로 기울려져 가해지는 충격을 흡수하는 것이다.When an impact is applied to the installed bollard 1 by a vehicle or the like, the bolt 16 is inclined as shown in FIG. 4 by the elasticity of the shock absorbing member 14 and the flow hole 12a of the first disc 12. One pipe 10 is inclined to one side to absorb the impact applied.

그리고 가해지던 충격이 해소가 되면 스프링(13)과 완충부재(14)의 탄성에 의해 제1파이프(10)가 원위치로 복구하게 되는 것이다.Then, when the impact applied is eliminated, the first pipe 10 is restored to its original position by the elasticity of the spring 13 and the buffer member 14.

또한 차량의 진입 등을 허용하여야 하는 경우는 고정볼트(24)와 고정너트(23)를 풀고 도 3의 도시와 같이 외피(11)가 입혀진 제1파이프(10)를 제2파이프(20)의 내측으로 하강시켜줌으로서, 차량 등의 진입을 허용할 수 있는 것이다.In addition, when the entry of the vehicle should be allowed, the fixing bolt 24 and the fixing nut 23 are loosened, and the first pipe 10 coated with the outer shell 11 as shown in FIG. 3 is connected to the second pipe 20. By descending to the inside, it is possible to allow entry of the vehicle.

한편, 차량 충격 등으로 훼손된 볼라드(1)를 교체해야 할 경우는 앵커볼트 너트(22a)(22b)를 풀고 외피(11)가 입혀진 제1파이프(10)만 교체해줌으로서, 볼라드(1)의 유지 보수가 용이한 것이다.  On the other hand, when it is necessary to replace the bollard (1) damaged by the impact of the vehicle, etc. by loosening the anchor bolt nuts (22a, 22b) and replace only the first pipe (10) coated with the outer shell 11, It is easy to maintain.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
