Description

우천시 야간 시인성이 향상된 도로 경계블록 및 그 제조방법{Road Boundary Block with Rainy Wet-Nighttime Visibility and Manufacturing Method of thereof}Road Boundary Block with Rainy Wet-Nighttime Visibility and Manufacturing Method of thereof

본 발명은 우천시 야간 시인성이 향상된 도로 경계블록 및 그 제조방법에 관한 것으로, 보다 상세하게는 장마 기간에 야간 시인성이 떨어지는 문제와 일정 시간이 경과한 후에 반사율이 떨어지는 문제를 해결할 수 있는, 우천시 야간 시인성이 향상된 도로 경계블록 및 그 제조방법에 관한 것이다.The present invention relates to a road boundary block with improved night visibility in rainy weather and a method for manufacturing the same, and more particularly, to solve the problem of poor visibility at night during the rainy season and the problem of the reflectance falling after a certain period of time has elapsed, night visibility in rainy weather It relates to an improved road boundary block and a manufacturing method thereof.

일반적으로, 도로 경계블록은 도로의 중앙 부분에 설치되어 도로의 경계를 나누고, 주차장 등에서 차량의 주차범위를 넘어서는 것을 방지할 수 있도록 한 주차 제한턱으로 사용되는 것이다.In general, the road boundary block is installed in the central part of the road to divide the boundary of the road, and is used as a parking limit to prevent the vehicle from exceeding the parking range in a parking lot.

이상과 같은 도로 경계블록은 상면 또는 측면에 반사판을 구비하여서 야간에 차량의 불빛에 반사되어 차량이 도로의 경계 등을 운전자가 쉽게 인지할 수 있도록 하고 있다.The road boundary block as described above is provided with a reflector on the upper surface or the side so that the vehicle is reflected by the light of the vehicle at night so that the driver can easily recognize the boundary of the road.

또한, 상기 도로 경계블록의 상면에는 봉상으로 이루어진 도로 안전봉을 설치하여서 도로의 경계를 명확히 하고, 도로 안전봉 사이를 연결하여서 도로 안전 휀스를 형성하여 보행자들이 함부로 넘어가지 못하게 하고 있다.In addition, a road safety bar made of a rod is installed on the upper surface of the road boundary block to clarify the boundary of the road, and a road safety fence is formed by connecting the road safety rods to prevent pedestrians from crossing.

그러나, 상기한 바와 같은 도로 경계블록은 자동차의 불빛에 반사되게 구성되어 있어 그 시인성이 떨어지는 문제점이 있었다.However, the road boundary block as described above is configured to reflect the light of the vehicle, there is a problem that the visibility is poor.

그리고, 통상 도로의 바닥에 설치되는 표지병은 몸체에 반사판이 단순 결합되어 있어 빗물에 대한 보호가 이루어져 있지 않아 그 내구성이 떨어져 쉽게 고장나는 등의 문제점이 있었다.In addition, the sign bottle, which is usually installed on the floor of the road, has a problem in that the reflector is simply coupled to the body, and thus the protection against rainwater is not made, so that the durability is low and it is easily broken.

또한, 표지병이 도로의 바닥에 고정 설치되어 있어 운행 중인 차량에 의하여 파손되는 문제점이 있었다.In addition, there is a problem in that the sign is fixed to the floor of the road and is damaged by a moving vehicle.

상기와 같은 문제점을 해결하기 위하여, 대한민국등록특허공보 제10-1165156호(2012.07.12.)에는 발광 표지병을 갖는 도로 경계블록이 개시되어 있다.In order to solve the above problems, Republic of Korea Patent Publication No. 10-1165156 (2012.07.12.) discloses a road boundary block having a light emitting sign.

상기 발광 표지병을 갖는 도로 경계블록은 도로 경계블록에 솔라셀 전원에 의하여 야간 발광되는 표지병을 구비함으로써, 별도의 외부 전원 공급 없이 야간 시인성이 향상되어 운전자에게 도로 및 주차장의 경계를 명확하게 인지시켜 안전사고가 방지되는 장점이 있지만, 장마 기간에는 솔라셀이 충전이 되지 않아 야간 시인성이 떨어지는 단점이 있다.The road boundary block with the light-emitting sign is provided with a sign that is illuminated at night by solar cell power on the road boundary block, so that night visibility is improved without a separate external power supply, so that the driver clearly recognizes the boundary between the road and the parking lot for safety Although it has the advantage of preventing accidents, there is a disadvantage that the visibility at night is lowered because the solar cell is not charged during the rainy season.

한편, 또 다른 용도의 도로 경계블록은 보도 분리선에 설치되어 인도와 도로를 구획하여 보행자를 안전하게 보호할 수 있도록 한다.Meanwhile, a road boundary block for another purpose is installed on the sidewalk dividing line to divide the sidewalk and the road to safely protect pedestrians.

경계블록으로 사용되는 경계석은 자연 석재를 절단하여 만들어지는 자연석 경계석, 시멘트와 골재를 혼합하여 만드는 시멘트 경계석, 종석과 시멘트를 사용하여 표면을 연마해서 되는 경계석 및 플라스틱으로 된 경계석 등이 있는데 이들은 모두 빛을 반사할 수 없기 때문에 경계블록의 역할을 제대로 할 수 없다는 문제점이 있다.The boundary stones used as boundary blocks include natural stone boundary stones made by cutting natural stones, cement boundary stones made by mixing cement and aggregate, boundary stones made by grinding the surface using keystone and cement, and plastic boundary stones, all of which are light. There is a problem in that it cannot function as a boundary block properly because it cannot reflect.

상기 문제점을 해결학 위해, 대한민국등록특허공보 제10-0436545호(2007.09.04.)에는 반사플레이트가 부착된 도로용 야광반사 경계블록이 개시되어 있다.In order to solve the above problems, Republic of Korea Patent Publication No. 10-0436545 (2007.09.04.) discloses a luminous reflective boundary block for roads to which a reflective plate is attached.

상기 반사플레이트가 부착된 도로용 야광반사 경계블록은 반사플레이트를 경계블록 내부에 일체형으로 부착됨으로써 블록표면으로부터 반사플레이트가 내미지 않기 때문에 보행자의 장애가 되지 않으며, 반사플레이트의 반사체는 구상의 그라스 비드로 구성되어 반사휘도가 높아 원거리에서도 뛰어난 시인성을 발휘하는 장점이 있지만, 일정 기간이 경과한 후에는 반사율이 떨어지는 단점이 있다.The luminous reflection boundary block for roads to which the reflection plate is attached does not become an obstacle to pedestrians because the reflection plate is integrally attached to the interior of the boundary block and the reflection plate does not come out from the block surface, and the reflector of the reflection plate is a spherical glass bead. It has the advantage of exhibiting excellent visibility even from a distance due to its high reflective luminance, but has a disadvantage in that the reflectance decreases after a certain period of time has elapsed.
