일반적으로 배수로덮개는 건축물의 배수로에 설치되어 우천시 빗물을 배수하는 동시에 통행시 보행자의 발이나 차량의 타이어가 배수로에 빠지는 것을 방지하도록 되어 있다.In general, the drainage cover is installed in the drainage of the building to drain rainwater during rainy weather and prevent the pedestrian's foot or the tire of the vehicle from falling into the drainage.

이와 같은 건축용 배수로덮개 구조는 첨부도면 도 1에 도시된 바와 같이 건축물의 배수로(11) 상단모서리부분에 설치된 "L"자 모양의 단면형태를 갖는 앵글(12)(13)에 얹히는 사각틀 형태의 테두리(14)에 복수의 베어링바(15)가 일정한 간격으로 설치되어 있으며, 그 베어링바(15)와 직교방향으로 환봉형태의 보강바(16)가 베어링바(15)의 상단에 용접된다.Such a construction drainage cover structure has a rectangular frame form on the angle (12) (13) having a cross-sectional shape of the "L" shape installed in the upper edge portion of the drainage passage 11 of the building as shown in Figure 1 attached. A plurality of bearing bars 15 are provided on the edge 14 at regular intervals, and a reinforcing bar 16 having an annular bar shape is welded to the upper end of the bearing bar 15 in a direction perpendicular to the bearing bar 15.

그러나, 이와 같은 일반적인 배수로덮개(10)가 보도와 차도의 경계부분을 따라 설치되는 경우 단차에 의해 등판이 어렵게 되는 단점을 지니고 있었다.However, when such a general drainage cover 10 is installed along the boundary between the sidewalk and the driveway, it has a disadvantage in that climbing is difficult due to a step.

이를 위해 국내 특허 출원번호 제 10-2011-0077751호(명칭, 건축용 배수그레이팅)이 제안된 바 있으나 일반적인 배수로덮개가 갖고 있는 문제점인 카트나 유모차가 통과하는 경우 틈새가 넓어 바퀴가 빠지거나 통행시 덜컹거림이 심한 문제점은 여전히 해결하고 있지 못하고 있었다.To this end, Korean Patent Application No. 10-2011-0077751 (name, construction drainage grading) has been proposed, but when the cart or stroller, which is a problem of the general drainage cover, passes, the gap is wide and the wheel falls out or is loose when passing. The problem of severe murmuring was still not solved.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 카트 또는 유모차가 통행할 때 작은 바퀴가 빠지거나 걸리면서 덜컹거림을 방지할 수 있는 건축용 배수로 덮개 구조를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a construction drainage cover structure that can prevent the rattling when the cart or stroller pass or fall off.

이러한 본 발명의 목적을 달성하기 위하여 배수구멍을 갖는 플립덮개의 상단부를 베어링바의 하단부에 간격을 두고 경첩에 의해 설치하고, 플립덮개가 닫힌 상태에서 이웃한 경첩과의 간섭을 회피하기 위한 커팅홈을 플립덮개의 하단부에 형성하며, 앵글 위에 얹히는 평철받침판을 배수로덮개의 하부 좌우측 가장자리에 설치하고, 플립덮개의 하단부 일측면에 돌출리브를 형성하여 건축용 배수로 덮개 구조가 제공된다.In order to achieve the object of the present invention, the upper end of the flip cover having a drainage hole is installed by the hinge at intervals at the lower end of the bearing bar, and the cutting groove for avoiding interference with the neighboring hinge while the flip cover is closed. Is formed at the lower end of the flip cover, and the flat iron support plate mounted on the angle is installed at the lower left and right edges of the drainage cover, and a protruding rib is formed on one side of the lower end of the flip cover to provide a construction drainage cover structure.

이상에서 설명한 바와 같은 본 발명은 베어링바 사이를 플립덮개가 덮어서 가리는 구조로 되어 있기 때문에 카트나 유모차의 통행시 바퀴가 빠지는 것을 방지할 수 있는 것은 물론이고, 평판 형태의 플립덮개 위를 바퀴가 부드럽게 구르기 때문에 통행시 덜컹거림을 방지할 수 있는 효과가 있다.As described above, the present invention has a structure in which the flip cover is covered between the bearing bars to prevent the wheels from falling out when the cart or the stroller passes, as well as the wheels smoothly on the flat flip cover. Rolling has the effect of preventing rattling when passing.

또한, 본 발명은 강우량이 작은 경우에는 플립덮개에 형성된 배수구멍으로 충분한 배수가 가능하기 때문에 배수로덮개를 뒤집는 수고를 덜 수 있으며, 강우량이 많은 경우 배수로덮개를 180° 뒤집어서 설치하게 되면, 플립덮개가 자중에 의해 개방되면서 충분한 배수가 가능하게 되는 효과가 있다.In addition, the present invention can reduce the effort of overturning the drainage cover because the drainage hole formed in the flip cover is sufficient drainage when the rainfall is small, and when the rainfall cover is installed by flipping the drainage cover 180 °, the flip cover is It is effective to allow sufficient drainage while being opened by its own weight.

더 나아가서 베어링바와 플립덮개 사이에 간격(G)이 형성되어 있기 때문에 플립덮개가 닫힐 때 이웃한 플립덮개가 베어링바 위에 얹혀서 지지되어 견고한 지지력을 얻을 수 있는 효과가 있다.Furthermore, since the gap G is formed between the bearing bar and the flip cover, when the flip cover is closed, the adjacent flip cover is supported by being placed on the bearing bar to obtain a firm supporting force.

또, 플립덮개에 형성된 커팅홈에 의해 플립덮개가 닫힐 때 경첩에 간섭되는 것을 방지할 수 있으며, 플립덮개의 일측면에 형성된 돌출리브에 의해 플립덮개가 수평상태를 유지할 수 있는 효과도 있다.In addition, it is possible to prevent the interference of the hinge when the flip cover is closed by the cutting groove formed in the flip cover, there is also an effect that the flip cover is maintained in a horizontal state by the protrusion rib formed on one side of the flip cover.

또한, 배수로덮개의 좌우측 가장자리에 설치된 평철받침판은 플립덮개가 미처 가리지 못한 부분을 가리는 구조로 되어 있기 때문에 바퀴 통과시 부드러운 통행이 가능하게 되는 효과가 있다.In addition, the flat support plate installed on the left and right edges of the drainage cover has a structure that covers the part that the flip cover does not cover, there is an effect that enables smooth passage when passing the wheel.

이하 본 발명에 따른 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 2 내지 도 8에 도시된 바와 같이 배수구멍(32)을 갖는 플립덮개(30)의 상단부를 베어링바(22)의 하단부에 간격(G)을 두고 경첩(34)에 의해 설치하고, 플립덮개(30)가 닫힌 상태에서 이웃한 경첩(34)과의 간섭을 회피하기 위한 커팅홈(36)을 플립덮개(30)의 하단부에 형성하며, 앵글(24)(26) 위에 얹히는 평철받침판(40)(42)을 배수로덮개(20)의 하부 좌우측 가장자리에 설치하고, 플립덮개(30)의 하단부 일측면에 돌출리브(38)를 형성한다.As shown in FIGS. 2 to 8, the upper end of the flip cover 30 having the drain hole 32 is provided by the hinge 34 with a gap G at the lower end of the bearing bar 22. A cutting groove 36 is formed at the lower end of the flip cover 30 to avoid interference with the neighboring hinge 34 in the state that the flip cover 30 is closed, and is placed on the angles 24 and 26. The support plates 40 and 42 are installed at the lower left and right edges of the drainage cover 20, and protruding ribs 38 are formed at one side of the lower end of the flip cover 30.

우천시 배수로(21)를 흐르는 우수의 흐름을 원활하게 하기 위해 플립덮개(30)에 형성된 배수구멍(32)은 전후방향으로 관통되도록 형성하며, 그 배수구멍(32)은 배수량을 증대시키기 위해 좌우방향으로 일정한 간격을 이루도록 복수개 형성할 수 있다.In order to facilitate the flow of rainwater flowing through the drainage passage 21 in rainy weather, the drainage hole 32 formed in the flip cover 30 is formed to penetrate back and forth, and the drainage hole 32 has a left and right direction to increase the drainage amount. It may be formed in plurality so as to form a constant interval.

경첩(34)은 파이프 형태이며 베어링바(22)의 하단부와 플립덮개(30)의 상단부에 용접한 후 조립시 중심이 일치하도록 한 상태에서 힌지핀(35)으로 끼워서 결합한다. The hinge 34 is pipe-shaped and welded to the lower end of the bearing bar 22 and the upper end of the flip cover 30, and then fitted by a hinge pin 35 in a state where the centers coincide with each other during assembly.

베어링바(22)와 플립덮개(30) 사이에 형성된 간격(G)은 플립덮개(30)가 닫혔을 때 이웃한 플립덮개(30)가 베어링바(22)에 접촉하여 지지되도록 하기 위함이며, 플립덮개(30)에 형성된 커팅홈(36)은 플립덮개(30)가 베어링바(22)에 지지될 때 경첩(34)에 간섭되는 것을 방지하기 위해 경첩(34)에 해당하는 부위보다 약간 크게 커팅한 것이다.The gap G formed between the bearing bar 22 and the flip cover 30 is to allow the adjacent flip cover 30 to contact and be supported by the bearing bar 22 when the flip cover 30 is closed. The cutting groove 36 formed in the flip cover 30 is slightly larger than the portion corresponding to the hinge 34 to prevent the flip cover 30 from interfering with the hinge 34 when the flip cover 30 is supported by the bearing bar 22. It is cut.

플립덮개(30)의 하단부 일측면에 형성된 돌출리브(38)는 플립덮개(30)가 닫혔을 때 수평을 이루도록 플립덮개(30)의 일측면으로부터 소정거리(L)로 돌출시켜서 형성한다.The protruding rib 38 formed on one side of the lower end of the flip cover 30 is formed by protruding at a predetermined distance L from one side of the flip cover 30 so as to be horizontal when the flip cover 30 is closed.

배수로덮개(20)의 하단부 좌우측에 설치되는 평철받침판(40)(42)은 배수로덮개(20)를 뒤집어서 플립덮개(30)에 의해 베어링바(22) 사이의 틈을 막는 경우 플립덮개(30)에 의해 가려지지 못한 부위를 가리는 역할을 하게 되며, 평철받침판(40)(42)은 배수로덮개(20) 하단부에 용접한다.The flat iron support plates 40 and 42 installed on the left and right sides of the lower end of the drainage path 20 are flipped over when the drainage cover 20 is flipped to prevent the gap between the bearing bars 22 by the flip cover 30. It serves to cover the portion that is not covered by, the flat support plate 40, 42 is welded to the bottom of the drainage cover (20).

도면 중 미설명 부호 50은 경계석을 나타낸 것이며, 60은 보도를 나타낸 것이다.In the drawings, reference numeral 50 denotes a boundary stone, and 60 denotes a sidewalk.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 2 및 도 3에 도시된 바와 같이 플립덮개(30)가 상부에 위치되도록 배수로덮개(20)를 설치한 경우에는 플립덮개(30)가 경첩(34)을 중심으로 회전하여 수평하게 되면서 닫히게 된다.2 and 3, when the drainage cover 20 is installed such that the flip cover 30 is positioned at the top, the flip cover 30 is rotated about the hinge 34 to be horizontal. It is closed.

이때 플립덮개(30)가 닫힐 때 양쪽으로 회전할 수 있기 때문에 플립덮개(30)에 형성된 돌출리브(38)가 베어링바(22)에 접촉하도록 배수로덮개(20)를 뒤집을 때 일측으로 조심스럽게 기울이게 되면, 모든 플립덮개(30)를 동일한 방향으로 회전시킬 수 있게 된다.At this time, since the flip cover 30 can be rotated on both sides when the flip cover 30 is closed, the tip rib 38 formed on the flip cover 30 is inclined to be carefully tilted to one side when the drainage cover 20 is turned over so as to contact the bearing bar 22. If so, all the flip cover 30 can be rotated in the same direction.

또, 베어링바(22)와 플립덮개(30) 사이에 형성된 간격(G)에 의해 이웃한 플립덮개(30)가 닫히면서 베어링바(22)에 지지되며, 플립덮개(30)에 형성된 커팅홈(36)은 경첩(34)으로부터 플립덮개(30)이 간섭되는 것을 방지하는 작용을 하게 된다.In addition, the adjacent flip cover 30 is supported by the bearing bar 22 while the adjacent flip cover 30 is closed by the gap G formed between the bearing bar 22 and the flip cover 30, and the cutting groove formed in the flip cover 30 is provided. 36 serves to prevent the flip cover 30 from interfering with the hinge 34.

또한, 플립덮개(30)의 일측면에 형성된 돌출리브(38)는 베어링바(22)에 지지되는 플립덮개(30)가 수평을 유지할 수 있도록 하는 작용을 하게 된다.In addition, the protruding rib 38 formed on one side of the flip cover 30 serves to keep the flip cover 30 supported by the bearing bar 22 to be horizontal.

이와 같이 플립덮개(30)가 닫힌 상태에서 카트 또는 유모차가 통과하는 경우 플립덮개(30)에 의해 바퀴가 베어링바(22)의 사이로 빠지거나 걸리면서 덜컹거리는 것을 방지할 수 있게 된다.In this way, when the cart or the baby carriage passes through the flip cover 30 in a closed state, the wheel may be prevented from being rattled while being pulled out or caught between the bearing bars 22 by the flip cover 30.

또, 배수로덮개(20)의 좌우측에 설치된 평철받침판(40)(42)은 플립덮개(30)가 미처 가리지 못한 부위를 가리고 있으므로, 바퀴가 안전하고 부드럽게 통과할 수 있다.In addition, since the flat cover plate 40, 42 installed on the left and right sides of the drainage cover 20 covers the portion that the flip cover 30 does not cover, the wheel can pass safely and smoothly.

그리고, 강수량이 작은 경우에는 플립덮개(30)에 형성된 배수구멍(32)으로 빗물이 충분하게 통과되므로, 뒤집지 않고 그대로 두며 강수량이 많은 경우 180° 뒤집어서 플립덮개(30)를 개방시킨다.In addition, when the precipitation is small, since the rainwater is sufficiently passed through the drain hole 32 formed in the flip cover 30, it is left without flipping, and when the precipitation is large, the flip cover 30 is opened by flipping 180 °.

한편, 강수량이 많아 배수로덮개(20)를 통한 배수량을 충분하게 확보할 필요가 있는 경우에는 첨부도면 도 4 내지 도 7에 도시된 바와 같이 플립덮개(30)가 밑으로 향하도록 배수로덮개(20)를 180° 뒤집어서 설치하게 되면, 플립덮개(30)가 자중에 의해 경첩(34)을 중심으로 회전되면서 베어링바(22)의 하단부에 수직으로 개방된다.On the other hand, if there is a lot of precipitation, it is necessary to ensure a sufficient amount of drainage through the drainage cover 20, the drainage cover 20 so that the flip cover 30 is directed downward as shown in the accompanying drawings 4-7. If the installation is turned upside down 180 °, the flip cover 30 is rotated about the hinge 34 by its own weight and is vertically opened to the lower end of the bearing bar 22.

이와 같이 플립덮개(30)이 개방된 상태에서 배수로(21)를 통해 빗물 등이 흐르는 경우 플립덮개(30)에 형성된 배수구멍(32)을 통해 빗물이 통과되기도 하지만 빗물의 흐르는 힘에 의해 플립덮개(30)가 밀리면서 흐르는 방향으로 약간 기울어서 흐름에 도움을 주는 작용도 하게 된다.As such, when rainwater flows through the drainage passage 21 while the flip cover 30 is opened, rainwater may pass through the drain hole 32 formed in the flip cover 30, but the flip cover is caused by the flowing force of the rainwater. (30) is pushed slightly in the direction of the flow will also help to flow.

또, 배수로덮개(20)에 설치된 평철받침판(40)(42)은 앵글(24)(26)에 안착되어 배수에는 영향을 거의 미치지 않게 된다.In addition, the flat support plate 40, 42 provided in the drainage cover 20 is seated on the angle (24) (26) has little effect on the drainage.
