본 발명은 배수용 집수구에 관한 것이다. 더욱 구체적으로 돌기와 결합홈에 의하여 연결되는 집수용 배수구와 연결 배수관의 결합에 있어서, 집수용 배수구를 구성하는 배수관 내부에 상기 돌기를 형성시켜, 결합홈이 형성된 연결배수관이 상기 배수관 안쪽으로 삽입되면서 상기 결합홈에 돌기가 결합되게 함으로써, 돌기 및 결함홈의 결합부를 위한 별도의 공간이 필요 없도록 하고, 배수관의 유수의 누수를 방지할 수 있도록 연결배수관의 결합홈 하부에 배수관의 하부가 삽입되며 연통공이 형성된 플랜지관을 형성시킨 배수용 집수구에 관한 것이다.The present invention relates to a sump for drainage. More specifically, in the coupling of the water collecting drain and the connection drain pipe connected by the projection and the coupling groove, by forming the projection inside the drain pipe constituting the water collecting drain, the connection drain pipe formed with the coupling groove is inserted into the drain pipe; By allowing the projection to be coupled to the coupling groove, a separate space for the coupling portion of the protrusion and the defective groove is not required, and the lower portion of the drain pipe is inserted into the lower portion of the coupling groove of the connection drain pipe so as to prevent the leakage of water from the drain pipe. It relates to a drainage catchment for forming the formed flange pipe.

본 발명의 출원인은 도 1a와 같이 결합홈(11)이 형성된 연결배수관(10)을 집수부 하부에 돌기(21)가 형성된 배수관(20)과 배수관 주위에 일정간격을 두고 형성된 소켓관(30) 사이에 삽입시켜, 상기 연결배수관의 결합홈이 교량상판(40) 내부에서 배수관의 돌기와 결합되도록 한 배수용 집수구를 실용신안등록 제 316593호로 등록한 바 있다.Applicant of the present invention is a socket pipe 30 formed at a predetermined interval around the drain pipe 20 and the drain pipe formed with the projection 21 formed in the lower portion of the connecting drain pipe 10 is formed with a coupling groove 11 as shown in Figure 1a Inserted therebetween, the drainage catchment for the coupling groove of the connection drainage pipe is coupled to the projection of the drainage pipe in the bridge top plate 40 has been registered as Utility Model Registration No. 316593.

이는 교량상판 거푸집을 손상하지 않고서도 배수관에 연결배수관을 연결시킬 수 있으며, 상기 거푸집의 경사면에 맞추어 소켓관의 하부면을 형성시켜 정밀한 시공이 가능하도록 한 것이다.This can connect the connecting drain pipe to the drain pipe without damaging the formwork of the bridge deck, it is possible to precise construction by forming the lower surface of the socket tube in accordance with the slope of the formwork.

하지만 상기 배수용 집수구의 경우 배수관에 연결용배수관을 결합시키는 돌기와 결합홈의 결합부위를 별도로 설치되는 소켓관과 배수관사이의 공간(A)을 이용함으로써 소켓관(30)을 반드시 설치해야 하므로 시공공정이 복잡해질 수 있고, 공정이 복잡해지는 만큼 경제성이 떨어진다는 문제점이 지적되었다.However, in the case of the sump for drainage, the socket pipe 30 must be installed by using the space (A) between the socket pipe and the drain pipe, which separately install the coupling part of the protrusion and the coupling groove for coupling the drain pipe to the drain pipe, and thus the construction process. The problem has been pointed out that this can be complicated and economical as the process is complicated.

또한 실용신안등록 제 311577호의 경우에도 도 1b와 같이 배수관(50) 하부외주면에 돌기(51)를 형성시키고 상기 돌기에 대응한 맞물림홈(61)이 형성된 연결관(60)을 결합시키되, 상기 돌기와 결합홈의 결합부위를 배수관 주위에 설치된 덮개(70)에 의한 공간을 이용하게 한 경우에 있어서도 덮개의 설치에 의해 상기와 같은 동일한 문제점이 지적되었다.In addition, in the case of Utility Model Registration No. 311577, as shown in FIG. 1B, a protrusion 51 is formed on the lower circumferential surface of the drain pipe 50, and the connecting pipe 60 having the engagement groove 61 corresponding to the protrusion is coupled thereto. The same problem as described above has been pointed out by the installation of the cover also in the case where the coupling portion of the coupling groove is used by the space by the cover 70 provided around the drain pipe.

이러한 도 1a 및 도 1b의 경우의 배수용 집수구 모두는 연결배수관 또는 연 결관이 배수관 바깥쪽으로 삽입시킨다는 점에서 배수량의 감소요인을 없앨 수 있다는 장점은 있으나, 소켓관 또는 덮개를 설치에 의하여 교량상판콘크리트와 직접 접하지 않을 수 있는 공간확보(A)가 전제되어야 하므로 소켓관 또는 덮개의 설치에 의하여 위에서 살펴본 것과 같이 시공성 및 경제성의 측면에서 다소 불리한 점이 발견되었다.1A and 1B, all of the drainage catchment ports have the advantage of eliminating the reduction factor of the drainage in that the connecting drainage pipe or the connecting pipe is inserted into the drainage pipe outward, but by installing the socket pipe or the cover, the bridge top concrete Since the space (A) must not be in direct contact with the socket, the installation of the socket tube or the cover has been found to be somewhat disadvantageous in terms of workability and economics as described above.

본 발명의 목적은 돌기와 결합홈에 의한 배수관과 배수연결관의 결합을 이용하되 시공공정을 줄이고 경제적인 배수용 집수구를 제공하는 것이다.It is an object of the present invention to use a combination of the drain pipe and the drain connection pipe by the projection and the coupling groove to reduce the construction process and provide an economical drainage catchment.

본 발명의 다른 목적은 배수관 내부를 흐르는 유수의 누수를 효과적으로 방지할 수 있는 배수용 집수구를 제공하는 것이다.Another object of the present invention is to provide a drainage catchment port that can effectively prevent the leakage of running water flowing inside the drain pipe.

본 발명의 기술적과제를 달성하기 위하여 본 발명은 In order to achieve the technical problem of the present invention

둘째, 상기 결합부위가 배수관 내부에 이루어지기 때문에 배수관과 연결배수관 사이에서 유수가 누수되는 것을 방지하기 위해 연결배수관의 결합홈 하부에 배수관 하부가 삽입, 고정될 수 있는 플랜지관을 형성시키고, 상기 플랜지관으로부터 연결배수관으로 연통되는 연통공을 연결용배수관의 플랜지관에 형성시킨 것을 기술적 특징으로 한다.Second, because the coupling portion is made in the drain pipe to form a flange pipe that can be inserted, fixed to the lower portion of the drain pipe to the bottom of the coupling groove of the connection drain pipe to prevent water leakage between the drain pipe and the connection drain pipe, the plan The technical feature is that a communication hole communicating from the branch pipe to the connection drain pipe is formed in the flange pipe of the connection drain pipe.

본 발명을 보다 명확하고 용이하게 설명하기 위해서 이하 본 발명의 최선의 실시예를 첨부도면에 의하여 상세하게 설명하며, 본 발명에 따른 실시예는 여러 가지 다른 형태로 변형될 수 있으므로, 본 발명의 범위가 아래에서 설명되는 실시예에 한정되지 않는다.BRIEF DESCRIPTION OF DRAWINGS To describe the present invention more clearly and easily, the following describes the best embodiments of the present invention in detail with reference to the accompanying drawings, and embodiments according to the present invention may be modified in various other forms, and thus the scope of the present invention. Is not limited to the embodiment described below.

본 발명의 배수용 집수구(100)는 돌기(111)가 형성된 배수관(110) 및 상기 돌기에 대응한 결합홈(121)이 형성된 연결배수관(120)을 포함하되 상기 돌기가 결합홈에 끼워짐으로써 배수관과 연결배수관이 서로 연결되는 배수용 집수구에서, 상기 돌기(111)는 배수관(110) 내부 안쪽에 형성되고, 결합홈(121)이 형성된 연결배수관(120)이 배수관 내부에 삽입되어 배수관 내부에서 돌기가 결합홈에 끼워지도록 한다.Drainage catching device 100 of the present invention includes a drain pipe 110 is formed with a projection 111 and a connecting drain pipe 120 is formed with a coupling groove 121 corresponding to the projection, but the projection is fitted into the coupling groove In the water collecting port for drainage pipe and the connection drainage pipe is connected to each other, the protrusion 111 is formed inside the drainage pipe 110, the connection drainage pipe 120 having a coupling groove 121 is inserted into the drainage pipe in the drainage pipe Make sure that the projections fit into the coupling grooves.

도 2는 집수구 및 배수관으로 구성된 배수용집수구에서, 상기 집수부가 형성된 배수관(110) 내부에 형성된 돌기(111)가 연결용배수관(120)에 형성된 결합홈(121)에 삽입되는 설치상태도를 도시한 것이다.FIG. 2 is a view illustrating an installation state in which a protrusion 111 formed in the drain pipe 110 having the water collecting part is inserted into a coupling groove 121 formed in the connection drain pipe 120 in the drain collecting port formed of the water collecting port and the drain pipe. will be.

돌기(111)가 배수관 내부에 형성되는데, 이러한 돌기의 형상은 사각단면으로 형성시키는 것이 일반적이지만 다양한 형상으로 제작하는 것이 가능하고, 이러한 돌기는 배수량에 영향을 줄 수 있으므로 되도록 작게 형성시키는 것이 바람직하다.The protrusion 111 is formed inside the drain pipe, but the shape of the protrusion is generally formed in a rectangular cross section, but can be manufactured in various shapes, and it is preferable that the protrusion is formed as small as possible because it may affect the drainage amount. .

상기 돌기(11)는 연결배수관의 상부 단부에 형성된 결합홈(121)의 수직결합홈에 끼워져 수평결합홈쪽으로 끼워질 수 있도록 연결배수관을 배수관 내부에 삽입시켜 돌기가 결합홈과 끼워져 결합될 수 있도록 한다.The protrusion 11 is inserted into the vertical coupling groove of the coupling groove 121 formed at the upper end of the coupling drain pipe so that the protrusion is inserted into the drain pipe so that the protrusion is fitted with the coupling groove. do.

도 3은 집수부 및 돌기(111)가 내부면에 형성된 배수관(110)으로 구성된 배 수용집수구(100)에서, 배수관(110) 내부로 설치된 연결용배수관(120)이 교량용상판(200)에 설치된 상태를 도시한 것이다.3 is a drain receiving catchment port 100 composed of a drain pipe 110 having a water collecting part and a protrusion 111 formed on an inner surface thereof, and a connection drain pipe 120 installed inside the drain pipe 110 is disposed on the bridge plate 200. It shows the installed state.

상기 도 3에서 배수관(110) 내부면에 연결배수관(120)의 외부면이 서로 맞닿은 부위는 돌기(111)와 결합홈(121)의 결합을 위해서는 연결용 배수관의 회전이 필요하기 때문에 어느 정도 배수관과 연결배수관 사이는 약간의 이격된 틈이 형성될 수 있다. 즉 배수관(110) 내부에 연결배수관(120)이 너무 꽉 끼워져 삽입되면 연결배수관을 회전시키기 어렵기 때문에 연결배수관의 결합홈에 배수관의 돌기를 결합시키기 어려울 수 있다는 문제점이 있기 때문이다. 이에 어느 정도 틈을 형성시키는 경우 그 틈으로 배수관 내부로 흘러내리는 유수(W)가 누수될 우려가 있다. 이에 본 발명에서는 이러한 누수를 방지하기 위하여 그 틈으로 누수되는 유수를 연결배수관(120)으로 유도하기 위하여 결합홈(121) 하부에 연결배수관(120) 내부로 연통된 연통공(141)이 형성된 플랜지관(140)이 형성되도록 한다.In FIG. 3, the outer surface of the connection drainage pipe 120 contacts the inner surface of the drainage pipe 110 in order to couple the protrusion 111 and the coupling groove 121, so that the connection of the drainage pipe is necessary to rotate the drainage pipe to some extent. Some gaps may be formed between the connection pipe and the drainage pipe. That is, when the connection drainage pipe 120 is inserted into the drainage pipe 110 so tightly that it is difficult to rotate the connection drainage pipe, it is difficult to couple the projection of the drainage pipe to the coupling groove of the connection drainage pipe. If a gap is formed to some extent, there is a fear that water (W) flowing into the drain pipe may leak into the gap. Accordingly, in the present invention, in order to prevent such leaks, the communication hole 141 communicating with the connection drainage pipe 120 inside the coupling groove 121 is formed in order to guide the flowing water leaked into the gap into the connection drainage pipe 120. The branch pipe 140 is formed.

상기 플랜지관(140)은 연결배수관의 직경보다 크게 형성되어 플랜지관과 연결배수관사이에는 일정한 공간이 형성된다. 이러한 공간에 배수관(110) 하부가 삽입되어 고정된다. 배수관의 돌기와 결합홈이 서로 끼워져 결합될 수 있을 정도로 플랜지관으로 삽입되는 배수관 하부의 깊이를 조절하고, 상기 플랜지관은 교량상판 하부콘크리트에 미리 형성시킨 삽입홈에 삽입될 수 있도록 하여 외관상으로도 미려한 배수용 집수구를 설치할 수 있게 된다.The flange pipe 140 is formed larger than the diameter of the connection drainage pipe is formed a constant space between the flange pipe and the connection drainage pipe. The lower portion of the drain pipe 110 is inserted into this space and fixed. The depth of the lower part of the drain pipe inserted into the flange pipe is adjusted to the extent that the projections and the coupling grooves of the drain pipe can be combined with each other, and the flange pipe can be inserted into the insertion grooves formed in the lower concrete of the bridge deck in advance so that the appearance is beautiful. A drainage catchment can be installed.

이때 배수관과 연결배수관의 접촉부위를 따라 누수될 수 있는 유수(W)는 플랜지관(140)에 집수될 수 있으므로 플랜지관으로부터 연결배수관을 연통하는 구멍(141)을 형성시킴으로서 상기 집수된 누수를 연결배수관 내부로 유도될 수 있도록 한다.At this time, the water (W) that can be leaked along the contact portion of the drain pipe and the connecting drain pipe can be collected in the flange pipe 140, thereby forming a hole 141 communicating with the connection drain pipe from the flange pipe to connect the collected water leak. Allow it to be guided into the drain.

본 발명의 배수용 집수구는 배수관 내부 안쪽에 돌기를 형성시키고, 상기 배수관의 돌기가, 상기 배수관 내부에 삽입되는 연결배수관의 결합홈에 끼워져 결합됨으로서, 종래와 같이 상기 돌기 및 결합홈의 결합을 위한 공간을 확보하기 위하여 설치되는 소켓관 또는 덮개가 필요없어 불필요한 작업공정이 줄어들어 시공이 간편하며, 상기 연결배수관에 연통공이 형성된 플랜지관을 설치함으로서 배수관 내부에 삽입되는 연결배수관과의 틈새로 유수가 누수되는 것을 방지할 수 있고, 교량상판의 설치에 있어서도 외관이 미려하여 시공성 및 사용성이 우수한 배수용 집수구 설치가 가능하다.The drainage catchment of the present invention forms a projection inside the drain pipe, and the projection of the drain pipe is coupled to the coupling groove of the connection drain pipe inserted into the drain pipe, thereby combining the projection and the coupling groove as in the prior art. No need for socket tube or cover installed to secure the space, which reduces unnecessary work process and facilitates the construction, and by installing a flange tube with a communication hole formed in the connection drainage pipe, the water leaks due to a gap with the connection drainage pipe inserted into the drainage pipe. It can be prevented, and even in the installation of the bridge deck, the appearance is beautiful, and it is possible to install a drainage catchment port having excellent workability and usability.
