A connection using a nut is disclosed.
[문헌 2][Document 2]
국내특허등록 제0468227호에 ‘탈출 수단을 갖는 수로용 블럭’에 대한 내용 이 개시되어 있다.Korean Patent Registration No. 0468227 discloses the contents of 'a channel block having a escape means.'
위 [문헌 2]에서는, 수로용 블럭의 바닥체에 전후 방향으로 연결단턱을 각각 형성하고, 상기 연결단턱에는 상광하협 형태를 가지는 암수의 위치고정홈과 위치고정돌기가 각각 형성되어, 상기 수로용 블럭 연결시에 하나의 수로용 블록에 다른 수로용 블록이 슬라이딩되어 두 수로용 블럭이 결합하는 내용이 개시되어 있다.In the above [Document 2], the connecting step is formed on the bottom of the waterway block in the front and rear direction, respectively, the position fixing groove and the position fixing projection of the male and female having a form of light beams and narrows are formed on the connecting step, respectively, Disclosed is a combination of two waterway blocks by sliding another waterway block to one waterway block at the time of block connection.
[문헌 3][Document 3]
국내실용신안등록 제0301139호에 ‘콘크리트 수로관의 연결구조’에 대한 내용이 개시되어 있다.In Korea Utility Model Registration No.0301139, the contents of the connection structure of concrete water pipes are disclosed.
위 [문헌 3]에서는, 고분자합성수지재의 체결판을 구비하고, 수로관 블럭 선단부 내주면을 따라 안착부가 형성되어, 두 수로관 블럭을 맏대고, 각 안착부에 체결판을 안착하고, 별도의 체결부재로 체결판을 고정하는 방법에 의해 두 수로관 블럭을 연결하는 구조에 대한 내용이 개시되어 있다.In the above [Document 3], provided with a fastening plate of the polymer synthetic resin material, the seating portion is formed along the inner circumferential surface of the end of the waterway pipe block, the two waterway pipe blocks first, seating the fastening plate on each seating portion, fastening with a separate fastening member Disclosed is a structure for connecting two water pipe blocks by a method of fixing a plate.
또한, 일반 건물 지하에 형성하는 수로는, 거푸집을 설치하고, 콘크리트 타설·경화하여 콘크리트 수로를 구성하게 되는데, 상기 구성된 수로의 길이가 길 경우에는 길이 방향을 따라 여러 개로 나누어 거푸집을 설치하게 되며, 이로 인해 콘크리트 수로 사이에는, 틈이 발생하고, 상기 틈은 별도의 이음이 필요하다.In addition, the channel formed in the basement of the general building, the formwork is installed, the concrete is poured into concrete to form a concrete channel, when the length of the configured channel is long, it is divided into several along the longitudinal direction to install the formwork, Because of this, a gap is generated between the concrete waterways, and the gap requires a separate joint.
그러나 [문헌 1]과 같이 수로 블럭의 보강 리브에 슬릿홈을 형성하여 볼트, 너트로 연결하는 경우에는, 상기 수로 블럭 자체가 콘크리트로 제작되기 때문에, 제작시에 슬릿홈을 형성하는데 어려움이 많았으며, 일반적인 수로 블럭을 땅을 파고 설치하는 것을 고려하였을 때, 수로 블럭 측벽 외부에서 볼트, 너트를 체결하기에는 시공상 어려움이 있었다.However, in the case of forming a slit groove in the reinforcing rib of the waterway block and connecting it with a bolt and a nut as in [1], since the waterway block itself is made of concrete, it was difficult to form a slit groove at the time of manufacture. Considering digging and installing general waterway blocks, it was difficult to install bolts and nuts outside the waterway sidewalls.
그리고 [문헌 2]와 같이 수로 블럭의 양단 하부에 암수의 위치고정홈과 위치고정돌기를 형성하는 경우에도, 수로 블럭의 구조를 복잡하게 하여, 제작의 어려움이 발생하는 문제점이 있으며, 이러한 [문헌 2]에 따른 수로 블럭이나, 수로 블럭의 양단에 형성된 단턱으로 수로블록을 연결하는 통상적인 수로 블럭은, 모두 연결하는 수로 블럭이 고정되지 않은 상태이므로, 날씨나 외력 등에 의해 유동이 발생하면서, 연결부분으로 수로를 흐르는 물이 외부로 새어 나올 가능성이 컸고, 이러한 누수로 인해, 수로에 흐르는 물의 유실되는 문제점이 있었으며, 수로로 흐르는 물이 유해한 것이라면 토양을 오염시키는 문제점이 있었다.In addition, even when the position fixing grooves and the position fixing protrusions of the male and female are formed at the lower ends of the channel blocks as shown in [Document 2], the structure of the water channel blocks is complicated, and there is a problem of difficulty in manufacturing. 2) As the waterway block according to 2] or a conventional waterway block connecting the waterway blocks to the step formed at both ends of the waterway block is connected to the waterway block due to the weather or external force, since the waterway blocks are not fixed, There was a high possibility that the water flowing through the water channel to the part leaked out, due to such leakage, there was a problem of the water flowing into the water channel, and if the water flowing into the water channel is harmful, there was a problem of contaminating the soil.
한편, [문헌 3] 과 같은 수로 블럭 연결 구조는, 체결판에 의해 두 수로 블럭이 체결판에 의해 서로 구속하면서 연결되는 특징이 있으나, 안착부 형성을 위해 수로 블럭의 구조가 복잡하고, 상기 체결부재를 사용하기 위해 체결판과 수로 블럭의 안착부에 관통된 체결구멍을 형성해야 하는데, 상기 체결구멍에 의해 수로 블럭의 구조 약화를 가져 올 수 있고, 상기 체결 구멍으로 누수가 발생할 수 있으며, 상기 체결판은 수력 블록의 유동이나 외력에 의해 파손될 우려가 많은 문제점이 있었다. On the other hand, the channel block connection structure as shown in [Document 3] is characterized in that the two channel blocks are connected to each other by a fastening plate by a fastening plate, but the structure of the waterway block is complicated to form a seat, and the fastening In order to use the member, it is necessary to form a fastening hole penetrating through the fastening plate and the mounting portion of the waterway block, and the fastening hole may cause the structure of the waterway block to be weakened, and leakage may occur into the fastening hole. Fastening plate has a lot of problems that are likely to be damaged by the flow or external force of the hydraulic block.
