본 발명은 도로의 배수구 등과 같은 트렌치에 장착되는 트렌치 커버에서 통행에 따라 발생하는 소음과 같은 문제를 근본적으로 해결하면서 제조 단가를 줄이고 환경 친화적이면서도 트렌치 커버에서 요구되는 강도 등의 기본 물성을 충족할 수 있을 뿐만 아니라 다른 원하는 특성을 부여할 수 있는 친환경 트렌치 커버 몰딩용 조성물 및 이 조성물에 의한 합성고무가 피복된 트렌치 커버에 관한 것이다.The present invention fundamentally solves problems such as noise generated by traffic in a trench cover mounted in a trench such as a drain of a road, reduces manufacturing costs, is environmentally friendly, and satisfies basic physical properties such as strength required for a trench cover. The present invention relates to an eco-friendly trench cover molding composition capable of imparting other desired properties, and a trench cover coated with synthetic rubber by the composition.
통상적으로 도로변, 주차장 또는 건축물 등에서의 빗물이나 오수를 배수 및 집수할 필요가 있는 장소에는 배수구를 포함한 트렌치가 배설되고, 또 통신 케이블용 지하 공간에 접근하기 위한 접근구도 다수 설치된다.Typically, trenches including drains are provided in places where it is necessary to drain and collect rainwater or sewage from roadsides, parking lots, or buildings, and a number of access ports for accessing the underground space for communication cables are also installed.
이러한 배수구 및 통신 케이블용 접근구의 상부에는 보행자의 발이나 차량의 바퀴 또는 기타 오물이 배수로 내부로 빠지는 것을 방지하기 위한 트렌치 커버가 배설된다.A trench cover is provided on the upper portion of the drain and the access port for communication cables to prevent the foot of a pedestrian, the wheel of a vehicle, or other dirt from falling into the drainage channel.
현재 사용되고 있는 대부분의 트렌치 커버는 주물에 의해 소정 형상으로 제작한 후 녹 방지를 위한 아연도금을 행하게 되며, 일체형 혹은 다수개의 트렌치 커버를 일렬로 조립하여 연결함으로써 전체 트렌치 커버를 구성하게 되므로, 인체에 유해하면서 도금 자체가 환경에 악영향을 줄 수 있다.Most of the trench covers currently used are manufactured in a predetermined shape by casting and then galvanized to prevent rust, and the entire trench cover is formed by assembling and connecting one-piece or multiple trench covers in a row. While harmful, the plating itself can adversely affect the environment.
이러한 트렌치 커버와 관련하여, 예를 들면 국내 특허등록 제10-0855057호(특허문헌 1)에서 제시된 바와 같이, 양측에 다수의 배수홈을 갖는 지지암이 형성되고 상향으로 볼록하게 휘어진 지지프레임, 이 지지프레임 양단에 일체로 형성한 연결프레임, 각각의 연결프레임 양측에 다른 트렌치 커버를 결합할 수 있도록 형성한 연결수단을 구비한 트렌치 커버가 개시되어 있다.With respect to such a trench cover, for example, as suggested in Korean Patent Registration No. 10-0855057 (Patent Document 1), a support frame having a plurality of drainage grooves on both sides is formed and a support frame that is convexly curved upward, Disclosed is a trench cover having a connecting frame integrally formed at both ends of a support frame, and connecting means formed to couple different trench covers to both sides of each connecting frame.
상기 특허문헌 1에 개시된 것과 같은 종래의 트렌치 커버들은 주물로 제작되어 트렌치가 제 위치에서 고정되지 않을 경우 차량의 통행에 의해 이격되고 이에 의해 소음이 발생하는 등 여러 문제가 발생한다.Conventional trench covers such as those disclosed in Patent Document 1 are made of a casting, and when the trench is not fixed in place, it is separated by the passage of a vehicle, thereby causing various problems, such as noise.
이러한 점을 해결하기 위하여 특허등록 제10-0894309호(특허문헌 2)에는 지면에 매립되는 트렌치가 배수로를 구비하면서 그 상단부 양측에 커버지지면이 일체로 형성되고, 커버지지면의 일측에 걸림턱이 일체로 형성되며, 상기 트렌치의 커버지지면에 대응되는 접촉면이 일체로 절곡되면서 그 단부에 걸림턱에 탄성지지되는 경사면이 더 구비되고, 상기 접촉면에는 그 길이방향에 각각 반대방향으로 향하는 지지판이 각각 돌출 설치되는 구성을 개시하고 있다.In order to solve this problem, Patent Registration No. 10-0894309 (Patent Document 2) has a trench buried in the ground having a drainage passage, and cover support surfaces are integrally formed on both sides of the upper end thereof, and a locking jaw is formed on one side of the cover support surface.

Each protruding configuration is disclosed.
또, 실용신안등록 제20-0480941호(특허문헌 3)에는 소정 곡률을 갖는 아치 형상으로 이루어진 몸체부; 이 몸체부의 일측에 인접한 다른 트렌치 커버와 결합되도록 형성되는 제1 결합부; 상기 몸체부의 타측에 인접한 다른 트렌치 커버와 결합되도록 형성되는 제2 결합부; 상기 몸체부의 중간에 인접한 다른 트렌치 커버와 결합되도록 형성되는 제3 결합부를 마련하여 트렌치 커버를 고정돌기부와 고정홈부에 의해 간편하게 조립할 수 있는 무소음 트렌치 커버를 개시하고 있다.In addition, Utility Model Registration No. 20-0480941 (Patent Document 3) includes a body portion made of an arch shape having a predetermined curvature; A first coupling portion formed to be coupled to another trench cover adjacent to one side of the body portion; A second coupling portion formed to be coupled to another trench cover adjacent to the other side of the body portion; Disclosed is a noiseless trench cover in which a trench cover can be easily assembled by fixing protrusions and fixing grooves by providing a third coupling portion formed to be coupled to another trench cover adjacent to the middle of the body portion.
그런데, 상기 특허문헌 2 및 3을 포함한 대부분의 종래에 제안된 기술은 단순히 트렌치 커버의 형태적인 구조에만 착안하여 소음 발생 등의 종래 문제를 해결하고자 하였으나, 만족할 만한 수준의 수준에는 도달하기 있지 못한 실정이다.However, most of the conventionally proposed technologies including Patent Documents 2 and 3 have attempted to solve conventional problems such as noise generation by focusing only on the morphological structure of the trench cover, but have not reached a satisfactory level. to be.
한편, 실용신안등록 제20-0469484호(특허문헌 4)에는 트렌치의 폭방향으로 긴 형상을 갖도록 합성수지로 성형되며, 상면에는 상하로 관통되는 배수공이 형성된 바디를 가지며, 이 바디의 일측 장변면에는 탄성후크가 돌출형성되고, 상기 바디의 타측 장변면에는 탄성후크에 정렬되는 위치에 결합공이 형성되며, 상기 바디의 단변면 양단부에는 상하로 관통되는 볼트체결공이 형성되어 탄성후크를 이웃되게 배치되는 트렌치 커버의 결합공에 삽입하여 이웃되는 트렌치커버와 연결조립되며, 상기 볼트체결공에 볼트를 체결하여 트렌치에 고정되고, 상기 바디의 길이방향 양단부 저면에는 완충패드가 구비되며, 상기 바디의 장변면에는 스페이서가 돌출형성되어 스페이서에 의해 이웃되게 조립되는 트레치 커버 사이에 공간이 형성되는 합성수지제 무소음 트렌치 커버에 대해 개시되어 있다.On the other hand, Utility Model Registration No. 20-0469484 (Patent Document 4) has a body formed of synthetic resin so as to have a long shape in the width direction of the trench, and has a body formed with drainage holes penetrating up and down on the upper surface, and on one long side of the body An elastic hook is formed protruding, a coupling hole is formed at a position aligned with the elastic hook on the other long side of the body, and bolt fastening holes penetrating up and down are formed at both ends of the short side of the body, so that the elastic hook is disposed adjacent to the trench. It is inserted into the coupling hole of the cover to connect and assemble with the neighboring trench cover, and the bolt is fastened to the bolt fixing hole to be fixed to the trench, and buffer pads are provided on the bottom surfaces of both ends of the body in the longitudinal direction, and the long side of the body Disclosed is a noiseless trench cover made of a synthetic resin in which a spacer is formed protruding and a space is formed between a trench cover that is assembled adjacently by a spacer.
그러나, 특허문헌 4의 기술 또한 단순히 특정 구성부분을 합성수지재로 형성하여 사용한다는 것만을 기술하고 이를 위한 일정한 구성을 개시하는 것으로, 트렌치 커버로서 요구되는 경도, 인장강도 등을 만족하고 있는지에 대해서는 개시된 바가 없다.However, the technology of Patent Document 4 also describes only the use of a specific component part formed of a synthetic resin material, and discloses a certain configuration for this, and whether it satisfies the hardness and tensile strength required as a trench cover is disclosed. There is no bar.
