본 발명은 불연속부가 없는 반타원형의 대형 탱크에 있어서, 탱크 정상부의 지지구에 관한 것이다.The present invention relates to a support for a tank top in a semi-elliptic large tank without discontinuities.

액화가스를 저온으로 저장하기 위하여 지상이중벽식 탱크의 지하 멤브레인(membrane)식 탱크등이 많이 건설되고 있는데, 탱크기지의 입지조건, 환경조건등의 관점에서 외벽을 콘크리트로한 콘크리트식이나 하이다이크(high dike)식 지상 탱크 또는 지하탱크가 검토되고 있지만, 종래로부터 건설되고 있는 지하탱크의 형식에서는 토목공사가 차지하는 비중이 높아 전체의 제작비용이 비싼 문제점이 있었다.In order to store the liquefied gas at low temperature, many underground membrane tanks, etc., of ground double wall tanks are being constructed.In terms of the location and environmental conditions of the tank base, concrete or high-heeled concrete with outer walls Although high dike type ground tanks or underground tanks are being considered, there has been a problem that the production cost of the entire construction is expensive because of the high proportion of civil engineering works in the type of underground tanks that have been conventionally constructed.

이 때문에 간단한 토목공사로서 공기(工期)를 짧게하고 제작비용이 적게드는 탱크가 검토되어, 제1도에 도시된 바와 같은 밑바닥이 편평한 반타원형의 탱크가 제안되기에 이르렀다.For this reason, tanks which shorten the air and reduce the production cost have been examined as a simple civil engineering work, and a semi-elliptic tank having a flat bottom as shown in FIG. 1 has been proposed.

이와 같은 탱크는 직경이 크고 깊이가 비교적 얕으며 용적율이 좋으나 불연속부가 없는 구조이므로 탱크벽에 강도를 갖게하여 탱크의 정상부가 함몰되는 경우를 방지할 필요가 있다. 이러한 이유로 인하여 탱크의 벽이나 정상부의 구조가 복잡해지고 중량도 증가하게 되어 탱크의 대형화에 큰 문제점으로 대두되고 있다.Since the tank is large in diameter, relatively shallow in depth, and has a good volume ratio but no discontinuities, it is necessary to give strength to the tank wall to prevent the top of the tank from sinking. For this reason, the structure of the wall or the top of the tank is complicated and the weight is also increased, which is a big problem in the enlargement of the tank.

본 발명은 이와 같은 탱크이 제결점을 시정하여 탱크내의 중앙부에 상하 2개로 분할시킨 지지구를 설치하여 정상부를 떠받치도록 하므로써 탱크벽의 구조를 간단하게 하고 경량화시킬 수 있게 하는 탱크 정상부의 지지구를 제공하기 위한 것으로서 이하 첨부된 예시도면에 의거 본 발명을 상세히 설명하면 다음과 같다.The present invention provides a support for the tank top to simplify and lighten the structure of the tank wall by supporting the top by installing a support divided into two upper and lower parts in the center of the tank by correcting the smelting point. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings as follows.

본 발명은 불연속부를 갖고 있지 않은 철판(1)을 반타원형상으로 하여 탱크(2)를 구성하며, 측면에 여러개의 적당한 크기의 구멍(3)을 갖는 원통형의 정상부 지지구(4)를 탱크(2)의 내부 중앙에 세워 설치하고 지지구(4)의 하단을 밑판(5)에 고정 부착함과 동시에 상단을 철판(1)의 정상부(6) 내측에 설치하여 탱크(2)의 중량을 떠받치도록 되어 있다.According to the present invention, the tank 2 is formed by using the iron plate 1 having no discontinuities in a semi-ellipse shape, and a cylindrical top support 4 having a plurality of appropriately sized holes 3 on the side is provided with a tank ( 2) installed in the center of the inside, and the lower end of the support (4) is fixed to the bottom plate (5) and at the same time the upper end is installed inside the top (6) of the iron plate (1) to support the weight of the tank (2) It is supposed to strike.

또한 상기 지지구(4)는 적당한 높이로 상측지지구(7) 및 하측지지구(8) 2개로 분할되며, 그 상, 하지지구(7, 8)이 각 원주상의 분할면둘레에 각각 원주사의 지지턱(9, 9')을 설치하여 분할된 각 지지구(7, 8)의 중심이 약간 옆으로 비껴진 경우에도 안정한 상태에서 떠받칠 수 있도록 하고, 원통모양의 지지구(4)내에 원통형의 액화가스의 주입관(10) 및 배출관(11)을 넣어 그 각각의 상부는 탱크(2)의 외부에 관통시켜 고정시키고, 탱크 내부에서는 링모양의 단면형상을 지닌 여러개의 가이드(12)에 의해 반고정시키며, 탱크(2)의 내피를 이루는 철판(1)의 가장자기 부분은 너클(knuckle) 모양의 코너부(13)로 되어 있고, 철판(1)의 외부에는 탱크(2)의 외피를 이루는 보호재(14)가 감싸여져 액화가스를 저온으로 유지시켜 준다.In addition, the support (4) is divided into two upper support (7) and the lower support (8) at a suitable height, the upper and lower support (7, 8) is a circumference of the circumference of each circumference on each circumference The support jaws 9, 9 ′ of the yarns are provided so that they can be held in a stable state even when the centers of the divided supports 7, 8 are slightly deflected sideways, and within the cylindrical support 4 The injection pipe 10 and the discharge pipe 11 of the cylindrical liquefied gas is put, and the upper part of each of them is fixed by penetrating the outside of the tank 2, the inside of the tank several guides 12 having a ring-shaped cross-sectional shape Semi-fixed, the most magnetic portion of the iron plate 1 forming the inner skin of the tank 2 is a knuckle-shaped corner portion 13, and the outside of the tank 2 is outside the iron plate 1 The protective material 14 forming the outer shell is wrapped to keep the liquefied gas at a low temperature.

탱크(2)내의 가스압이 높은 경우에는 철판(1) 전체가 팽창되어 밑판(5)에 대하여 정상부(6)가 위로 올라가게 되는데 지지구(4)가 2개로 분할되어 있기 때문에 철판(1)의 정상부(6)의 상승동작과 함께 상측지지구(7)가 들어 올려지며, 이때 정상부(6)에 고정된 주입관(10)과 배출관(11) 또한 반고정되어진 가이드(12)를 미끄러져 통과하여 정상부(6)의 상승동작과 함께 위로 들어 올려진다.When the gas pressure in the tank 2 is high, the entire iron plate 1 is expanded so that the top 6 rises with respect to the base plate 5, but since the support 4 is divided into two, The upper support 7 is lifted with the upward movement of the top part 6, and the injection pipe 10 and the discharge pipe 11 fixed to the top part 6 also slide through the semi-fixed guide 12. It is lifted up together with the upward motion of the top part 6.

탱크(2)내의 가스압이 낮은 경우에는 코너부(13)가 변형되어 철판(1) 전체가 자체의 무게에 의해 가라앉게 되는데 이때 철판(1) 정상부(6)의 하기동작과 함께 정상부(6)에 고정된 주입관(10)과 배출관(11)이 반고정되어진 가이드(12)를 미끄러져 통과하여 아래로 내려보내지며, 동시에 들어올려진 상측지지구(7)가 아래로 내려보내지면 상측지지구(7)가 하측지지구(8) 위에 놓여 지지되기 때문에 철판(1)의 정상부(6)가 가라앉게 되는 현상을 방지해준다.When the gas pressure in the tank 2 is low, the corner part 13 is deformed so that the entire iron plate 1 is sunk by its own weight. At this time, the top part 6 together with the following operation of the top part 6 of the iron plate 1. The injection pipe 10 and the discharge pipe 11 fixed to the slide down through the guide 12 is fixed semi-fixed and sent down, and at the same time the upper support (7) is lifted down the upper support Since 7 is supported on the lower support 8, the top 6 of the iron plate 1 is prevented from sinking.

상, 하지지구(7, 8)의 원주상분할면 둘레에는 각각 원주상의 지지턱(9, 9')을 설치하여, 상측지지구(7)의 중심이 하측지지구(8)의 중심에 대하여 약간씩 옆으로 이동된 경우에도 상측지지구(7)의 원주 상턱(9)이 하측지지구(8)의 원주상턱(9')에 걸려지기만 하면 하측지지구(8)가 상측지지구(7)를 버티어 주므로서 안전하게 철판(1)의 정상부(6)를 지지시켜 줄 수 있게 한다.The circumferential upper surface of the upper and lower regions (7, 8) are provided around the circumferential upper surface of the lower support (9, 9 '), respectively, so that the center of the upper support (7) at the center of the lower support (8) Even if it is slightly moved sideways with respect to the lower support (8) is the upper support only if the upper circumference (9) of the upper support (7) is caught by the upper circumference (9 ') of the lower support (8) By holding (7), it is possible to safely support the top (6) of the iron plate (1).

원통모양의 지지구(4) 측면에는 구멍(3)이 형성되어져 있으므로 이 구멍(3)을 통하여 지지구(4)내부로 액화가스가 들어갈 수 있고 탱크(2) 내부 용적이 거의 감소하는 일이 없으며 지지구(4)내에 상하로 이동이 가능하게 설치된 주입관(10) 및 배출관(11)을 통해 액화가스를 주입시키거나 배출시킬 수가 있다.Since the hole 3 is formed in the side surface of the cylindrical support 4, liquefied gas can enter into the support 4 through this hole 3, and the volume inside the tank 2 is almost reduced. It is possible to inject or discharge the liquefied gas through the injection pipe 10 and the discharge pipe 11 is installed to be able to move up and down in the support (4).

또한 주입관(10) 및 배출관(11)은 지지구(4)내에 링모양의 가이드(12)에 의한 상하이동이 가능하게 장치되어 있으므로 탱크(2)내압의 변화에 따라 철판(1)이 축소되거나 팽창되어 정상부(6)가 상하로 이동되는 변형에 적응할 수 있으며 배관라인의 파손을 방지할 수 있다.In addition, since the injection pipe 10 and the discharge pipe 11 are installed in the support 4 so as to be able to be moved by the ring-shaped guide 12, the steel plate 1 is reduced in accordance with the change in the internal pressure of the tank 2. The expansion can be adapted to the deformation in which the top 6 is moved up and down and can prevent damage to the piping line.

제3도는 본 발명의 다른 실시예로서, 상기 실시예에 있어서 원통모양의 지지구(4) 대신에 각(角) 기둥의 형상을 가진 트러스(15)를 탱크(2)내부 중앙에 세워 설치하여 상기 실시예와 같이 철판(1)의 중량을 지지토록 한 것이다. 각기둥형상의 트러스(15)는 측면에 원통형지지구(4)의 구멍(3)에 해당하는 다수의 구멍(도면에 표시되지 않음)이 형성되어져 있고, 상, 하 2개로 분할되며, 분할부의 선단에는 각각 지지턱(9, 9')이 설치되고 트러스(15) 내부에는 주입관(10) 및 배출관(11)(도면에 표시되지 않음)을 상, 하로 이동시킬 수 있도록 고정하여 두는 것은 상기의 실시예와 동일하다.3 is another embodiment of the present invention, in which the truss 15 having the shape of a square pillar is installed in the center of the tank 2 instead of the cylindrical support 4. As in the above embodiment, to support the weight of the iron plate (1). The prismatic truss 15 is formed with a plurality of holes (not shown) corresponding to the holes 3 of the cylindrical support 4 on the side, divided into two parts, the upper and lower parts. The support jaws 9 and 9 'are installed at the tip, respectively, and the truss 15 is fixed so that the injection pipe 10 and the discharge pipe 11 (not shown) can be moved up and down. Same as the embodiment of.

본 실시예에 있어서 트러스(15)에 의해서도 탱크(2)의 내부 가스압의 변동에 의한 뜨고 가라앉는 등의 철판(1)의 변형에 대응하여 탱크(2)의 정상부(6)를 지지할 수 있으며 철판(1)의 구조를 간단하게 하고 중량을 가볍게 할 수 있다.In this embodiment, the truss 15 can also support the top 6 of the tank 2 in response to deformation of the iron plate 1 such as floating and sinking due to fluctuations in the internal gas pressure of the tank 2. The structure of the iron plate 1 can be simplified and the weight can be reduced.

제4도는 본 발명의 지지구(4)를 평반형 원통탱크에 응용한 예로서 도면의 부호는 제2도와 동일하고 상기의 탱크(2)와 같이 정상부(6)를 지지할 수 있으며 철판(1)의 구조를 간단하게 하고 무게를 가볍게 할 수 있다.4 is an example in which the support 4 of the present invention is applied to a flat cylindrical tank, and the reference numerals of the drawings are the same as those of FIG. 2 and can support the top 6 as in the tank 2, and the iron plate 1 Can simplify the structure and lighten the weight.

이상의 설명에서와 같이 본 발명의 탱크 정상부의 지지구에 의하면, 상·하로 분할된 지지구에 의해 탱크의 정상부를 내측으로부터 지지하는 것으로서 탱크의 구조를 간단히 할 수 있으며 중량도 가볍게 할 수 있다. 특히 매끄러운 반타 원형의 탱크와 같은, 내부 가스압에 의해 변형되는 탱크의 정상부를 지지하는 지지구로서 아주 유효하다.According to the support of the tank top of the present invention as described above, by supporting the top of the tank from the inside by the support divided into the upper and lower, the structure of the tank can be simplified and the weight can be light. It is particularly effective as a support for supporting the top of a tank that is deformed by internal gas pressure, such as a smooth vanta round tank.
