Description
본 발명은 대형LPG FSO(LPG Floating Storage Offloading)선박의 탱크수용부 격벽(transverse bulkhead)구조에 관한 것으로 특히 탱크수용부와 탱크수용부 사이인 경계부에 위치하고, 상갑판(upper deck)과 하부버텀(bottom)사이의 상,하하중을 분산시킨 탱크수용부 격벽에 관한 것이다.The present invention relates to a tank bulkhead (transverse bulkhead) structure of a large LPG Floating Storage Offloading (LPG) vessel, and is particularly located at the boundary between the tank tank and the tank tank, and includes an upper deck and a bottom bottom. It relates to a tank accommodating partition wall in which the upper and lower loads are dispersed.
일반적으로 LPG 선박의 탱크수용부는 첨부 도면 도 1a에서 도시하는 바와같이 약 7개정도의 탱크가 수용되는 수용공간을 형성하고 이들 수용부는 각각 격벽으로 경계되어지며, 상부 갑판과 하부버텀과의 사이를 지지하게 된다. Generally, the tank accommodating portion of the LPG vessel forms an accommodating space in which about seven tanks are accommodated, as shown in FIG. 1A, and these accommodating portions are bounded by partition walls, respectively, between the upper deck and the lower bottom. Will be supported.
첨부 도면 도 1b는 이러한 탱크수용부사이의 경계구조인 격벽의 일반적인 구조를 도시한다. 이러한 격벽의 구조에 있어서 최근에는 격벽구조에 수직하중의 분산을 고려하기 위하여 수직보강재(vertical stiffener)가 구성된다.FIG. 1B shows a general structure of a partition wall which is a boundary structure between these tank accommodation portions. In the structure of such barrier ribs, a vertical stiffener is recently constructed to consider the distribution of vertical loads in the barrier rib structure.
그러나 이러한 종래의 수직보강재는 단지 수직방향의 하중을 그대로 바닥으로 전달하기 때문에 그 두께가 두꺼워야되고, 상부 갑판과의 밀착도는 물론 하부 버텀과의 밀착도를 높이기 위하여 설계전장보다 길게 연결되지 않으면 안되었으며,이와같은 격벽구조를 통하여 하부버텀의 하중이나 상부갑판의 하중을 이기기 위한 하중분산이 이루어지지 않았으며, 격벽의 두께가 두꺼워져 통로의 확보도 어려운 문제점도 있었다.However, these conventional vertical stiffeners only have to be thick because they transfer the load in the vertical direction as it is, and have to be connected longer than the design length in order to increase the adhesion with the upper deck as well as the lower bottom. Through such a bulkhead structure, the load distribution was not made to overcome the load of the lower bottom or the upper deck, and the thickness of the bulkhead was too thick to secure a passage.
이와같은 격벽의 하중을 효과적으로 분산하면서 지지해주고 통로를 확보하기 위한 격벽의 구조를 개선할 필요가 있었다.It was necessary to improve the structure of the bulkhead to support and secure the passage while distributing the load of the bulkhead effectively.
본 발명의 목적은 이와같은 종래 격벽구조가 갖는 단점을 보완하여 그 수직보강재의 수직하중을 분산하기 위한 격벽구조를 새롭게 제공함으로써 수직보강재의 전장을 줄여주고, 승강구 설치없이 탱크수용부와 수용부사이의 통로의 형성이 가능하게 하는 격벽을 제공하고자 한다.The object of the present invention is to compensate for the disadvantages of the conventional bulkhead structure by providing a new bulkhead structure for dispersing the vertical load of the vertical reinforcement to reduce the overall length of the vertical reinforcement, between the tank accommodating portion and the receiving portion without installing the hatch It is intended to provide a partition that allows the formation of passages.
본 발명의 목적은 수직보강재만의 격벽구조에 가로보와 세로보를 격자구조로 설치하여 수직하중을 유효하게 분산시키면서, 그 보강재들의 두께를 줄일 수 있어 승강구의 설치없이 진입공간의 확보가 가능해지고, 수직전장도 줄일 수 있는 격벽구조를 제공하는 데에 그 목적이 있다. An object of the present invention is to install the horizontal beams and vertical beams in the grid structure of the vertical reinforcement only to effectively distribute the vertical load, while reducing the thickness of the reinforcement, it is possible to secure the entry space without installing the hatch, vertical The purpose is to provide a bulkhead structure that can reduce the battlefield.
상기한 본 발명의 목적은 LPG선의 탱크격벽(LPG tank bulkhead)구조에 있어서, 수직보강재(vertical stiffener); 및 상기 수직보강재와 수직보강재사이에서 직각연결구조로 설치되는 적어도 3개 이상의 가로보(horizontal stringer)를 포함하는 LPG선의 탱크격벽구조로서 달성된다.An object of the present invention described above in the LPG tank bulkhead structure (LPG tank bulkhead) structure, a vertical stiffener (vertical stiffener); And at least three or more horizontal stringers installed at right angles between the vertical reinforcement and the vertical reinforcement.
본 발명의 상기 탱크격벽구조는 상기 수직보강재와 수직보강재 사이에 세로보(vertical web)를 설치함이 바람직하며, 상기 수직보강재와 수직보강재사이의 가로보가 상기 세로보와 격자구조로 연결됨이 바람직하다.In the tank bulkhead structure of the present invention, a vertical web is preferably installed between the vertical stiffener and the vertical stiffener, and the horizontal beam between the vertical stiffener and the vertical stiffener is connected to the vertical beam and the lattice structure.
이하 본 발명의 바람직한 실시예를 첨부 도면에 의거 설명한다.BEST MODE Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
첨부 도면중 도 2는 본 발명 LPG선의 탱크 격벽에서 수직보강재와 가로보의격자구조를 나타내는 종단면도이고, 도 3은 본 발명 LPG선의 탱크 격벽에서 세로보의 결합구조를 나타내는 종단면도이고, 도 4는 LPG선의 탱크 격벽에서 가로보와 세로보의 격자구조를 나타내는 일부 발췌사시도이다. In the accompanying drawings, Figure 2 is a longitudinal cross-sectional view showing a vertical reinforcement and the horizontal beam lattice structure in the tank bulkhead of the present invention LPG ship, Figure 3 is a longitudinal cross-sectional view showing a coupling structure of the vertical beam in the tank bulkhead of the present invention LPG ship, Figure 4 Some excerpts showing the lattice structure of cross beams and stringers in a tank bulkhead of a line.
상기 도면에 따르는 본 발명 LPG선의 탱크격벽구조는 수직보강재(110)와 가로보(120)와 세로보(130)로 이루어진다. Tank bulkhead structure of the present invention LPG ship according to the drawings consists of a vertical reinforcement 110, horizontal beams 120 and vertical beams 130.
가로보(120)와 세로보(130)는 상기 수직보강재(110)의 내측에서 서로 격자형태로 연결되며 이와같은 격자를 형성한 가로보(120)의 양끝을 수직보강재(110)에 다시 격자상으로 설치함으로써 그 두께를 줄이면서 진입통로(102)가 형성된 격벽을 제공하게 된다.The horizontal beams 120 and the vertical beams 130 are connected to each other in a lattice form inside the vertical reinforcement 110, and by installing both ends of the horizontal beams 120 forming the grids in the vertical reinforcement 110 again in a grid shape. Reducing the thickness to provide a barrier rib formed with the entry passage (102).
수직보강재(110)는 상갑판(104)에 전달되는 하중을 가로보(120)로 전달시키며, 3곳에 설치된 가로보(120)의 위치에서 지지될 수 있어서 수밀성 개념의 설계시 요구되는 수직보강재(110)의 전장을 줄일 수 있다. The vertical reinforcement 110 transmits the load transmitted to the upper deck 104 to the cross beam 120, and can be supported at the positions of the cross beams 120 installed at three locations, so that the vertical reinforcement 110 required for the design of the watertightness concept. You can reduce the battlefield.
가로보(120)는 격벽(100)에 수평방향으로 배치하여 수직보강재(110)를 지지하며, 별도의 승강구 설치없이 탱크수용부(10)와 탱크수용부(10) 사이에 충분한 간격의 통로(102)가 형성될 수 있다.The horizontal beam 120 is disposed in the horizontal direction on the partition wall 100 to support the vertical reinforcement 110, and the passage 102 of sufficient distance between the tank accommodating portion 10 and the tank accommodating portion 10 without installing a separate hatch. ) May be formed.
가로보(120)의 전장길이는 탱크의 횡단면의 길이에 비례하여 24m가 바람직하고, 만약 상기 가로보(120)가 없을 시에는 수직하중을 지탱하기 위해 수직보강재(110)의 두께(깊이)는 4~5m정도가 되어야 한다. 그런데, 선박의 횡격벽과 LPG탱크와의 간격이 1.8m로 제약을 받기 때문에 그 사이에 설치되는 수직 보강재(110)의 두께(깊이)는 LPG탱크 표면에 설치되는 단열재 두께등을 고려할때 최대깊이는 1.5m이내로 설계되어야 한다.따라서, 상기 수직보강재(110)의 두께(높이)를 1.5m로 유지하기 위해서는 상기 가로보(120)와, 가로보(120)와 수직으로 결합되는 세로보(130)가 필요하게 된다.상기 조건을 만족시키기 위하여 가로보(120)와 같은 깊이를 갖는 세로보(130)를 3곳 설치하여 격자상의 구조로 수직보강재(110)로 부터 가로보(120)로 전달된 하중을 다시 세로보(130)로 전달시켜 하중을 분배하게 된다. The total length of the cross beam 120 is preferably 24 m in proportion to the length of the cross section of the tank. If the cross beam 120 is absent, the thickness (depth) of the vertical reinforcement 110 is 4 to support the vertical load. It should be about 5m. However, since the space between the transverse bulkhead of the ship and the LPG tank is limited to 1.8m, the thickness (depth) of the vertical reinforcement 110 installed therebetween is the maximum depth in consideration of the thickness of the insulation material installed on the LPG tank surface. Therefore, the width of the vertical stiffener 110 should be designed to be within 1.5 m. Therefore, in order to maintain the thickness (height) of the vertical reinforcement 110 at 1.5 m, the horizontal beam 120 and the vertical beam 130 vertically coupled with the horizontal beam 120 are required. In order to satisfy the above conditions, the three beams 130 having the same depth as the horizontal beams 120 are installed so that the load transferred from the vertical stiffeners 110 to the horizontal beams 120 in a lattice structure is again applied to the vertical beams ( 130 to distribute the load.
이와같이 이루어진 본 발명 LPG선의 탱크수용부 격벽은 수직보강재만의 격벽구조에 가로보와 세로보를 격자구조로 설치하여 수직하중을 유효하게 분산시키면서, 그 보강재들의 두께를 줄일 수 있어 승강구의 설치없이 진입공간의 확보가 가능해지고, 수직전장도 줄일 수 있는 격벽구조를 제공하며, 이와같은 격벽은 종래 수직보강재만의 격벽이 갖는 단점을 보완하여 수직보강재의 수직하중을 분산하기 위한 격벽구조를 새롭게 제공하게 되며, 수직보강재의 전장을 줄여주어 수밀격벽으로서 기능,성능을 충분히 만족시키고, 격자구조를 도입하여 좁은 공간을 최대활용하고 부재치수를 줄여 원가절감을 가져오는 효과를 갖는다.The tank receiving portion bulkhead of the LPG ship of the present invention made as described above has horizontal beams and vertical beams arranged in a grid structure of a vertical reinforcement only to effectively distribute vertical loads, and reduce the thickness of the reinforcement, so that the thickness of the entrance space is not provided. It provides a barrier rib structure that can be secured and reduces the vertical electric field, and such a barrier rib provides a barrier rib structure for dispersing the vertical load of the vertical stiffener by supplementing the disadvantage of the barrier rib of the conventional vertical stiffener. It reduces the overall length of vertical stiffeners and satisfies the function and performance as a watertight bulkhead, and introduces lattice structure to maximize the use of narrow space and reduce the size of members, resulting in cost reduction.
