Abstract

The present invention relates to a method for assembling upper decks of a ship block. The present invention provides the method for assembling the upper decks of the ship block, which removes steps by chamfering the upper outside of a center partition wall to bend a protrusion of an upper deck protruding outwardly from the center partition wall due to heat deformation generated during welding when the first and second blocks are combined with each other, wherein the first block includes the center block and the second block does not. The purpose of the present invention is to provide the assembling method for combining the first block, which is composed of the center partition wall and has the protrusion protruding toward the upper deck therefrom, with the second block having no center partition wall formed thereon. The method comprises a first block forming step of forming the first block composed of the center partition wall which has the outer edge of the upper end chamfered; a protrusion bending step of bending the protrusion protruding downwards by heat-treating the lower part of the protrusion of the upper deck which protrudes toward the outside of the center partition wall of the first block; and a second block combining step of welding the upper deck of the second block to the protrusion which is bent downwardly.

Description

선박 블록의 상갑판 결합방법{Upper deck assembling method upper deck of ship block}[0001] The present invention relates to an upper deck assembling method,

본 발명은 선박 블록의 상갑판 결합방법에 관한 것으로, 중심격벽을 포함하는 제1블록과 중심격벽이 포함되지 않는 제2블록의 결합시 제1블록의 중심격벽 외측으로 돌출되는 상갑판의 돌출부와 제2블록의 상갑판의 단차를 서로 맞춰주면서 결합할 수 있도록 하는 선박 블록의 상갑판 결합방법.
The present invention relates to a method of joining an upper deck of a ship block, in which when a first block including a central bulkhead and a second block not including a central bulkhead are combined, a projecting portion of the upper deck protruding outside the central partition wall of the first block, A method for joining upper and lower decks of a ship block to each other to allow the upper decks of the blocks to be joined together while aligning the steps of the upper deck.

일반적으로 선박은 그 크기가 매우 크기 때문에, 선박을 일정 크기로 분할한 단위 크기의 블록을 별도로 제작한 후 이 블록을 서로 조립하여 제작된다. Generally, since the size of a ship is very large, a unit size block in which a ship is divided into a certain size is separately manufactured, and the blocks are assembled together.

도 1 은 선박블록의 횡조립 구조를 나타낸 예시도, 도 2 는 종래의 제1블록과 제2블록의 결합구조를 나타낸 예시도로서, FIG. 1 is an explanatory view showing a transverse assembling structure of a ship block, and FIG. 2 is an exemplary view showing a conventional joint structure of a first block and a second block.

도면에서와 같이 선박의 블록은 중심격벽(120)을 포함하는 제1블록(100)과 중심격벽을 포함하지 않는 제2블록(200)을 포함하여 구성된다. As shown in the figure, the block of the ship includes a first block 100 including a center partition 120 and a second block 200 without a center partition.

상기 제1블록(100)은 제2블록(200)과의 결합을 위하여 상갑판(110)이 중심격벽(120)의 외측으로 돌출되는 돌출부(120)가 형성되며, 상기 돌출부(120)와 제2블록(200)의 상갑판(210) 끝단이 용접됨으로써 제1블록(100)과 제2블록(200)이 결합된다. The first block 100 is formed with a protrusion 120 protruding to the outer side of the central partition wall 120 for coupling with the second block 200. The protrusion 120 and the second The first block 100 and the second block 200 are coupled by welding the upper end of the upper deck 210 of the block 200.

한편 상기 제1블록(100)과 제2블록(200)의 상갑판(110)(210)은 원활한 배수가 이루어질 수 있도록 외측을 향해 하향 경사진 형태로 설치되기 때문에 상기 제1블록(100)의 돌출부(111)는 중심격벽에서 상향경사지게 돌출된다. Since the upper and lower decks 110 and 210 of the first block 100 and the second block 200 are installed in a downward inclined form so as to smoothly drain the first and second blocks 100 and 200, (111) protrudes upward from the central partition wall.

따라서 상기 제1블록과 제2블록(200)의 결합시 제1블록(100)의 상갑판(110)과 제2블록(200)의 상갑판(210)이 서로 단차지게 형성됨으로써 용접이 어려운 문제점이 있다. The upper and lower decks 110 and 210 of the first block 100 and the upper deck 210 of the second block 200 are formed to be stepped on each other when the first block and the second block 200 are coupled to each other, .

이러한 문제점을 해결하기 위하여 종래에는 상기 돌출부(111)의 하부면을 가열하여 돌출부(111)가 하부방향으로 일부 휘어지도록 한 상태에서 제1블록(100) 상갑판(110) 돌출부(111)와 제2블록(200)의 상갑판(210)을 용접하였다. In order to solve this problem, in the related art, the lower surface of the protruding portion 111 is heated so that the protruding portion 111 is bent in a downward direction, and the protruding portion 111 of the upper block 110 of the first block 100, The upper deck 210 of the block 200 is welded.

그러나 상기와 같이 돌출부(111)의 하부면을 가열하여 돌출부(111)가 하부방향으로 휘어진다 하더라도 돌출부(111)의 돌출길이가 매우 짧아 돌출부(111)의 휘어지는 각도가 충분하지 않기 때문에 제2블록(200)의 상갑판(210)과의 용접시 단차가 발생되고 용접 불량 불량률이 매우 높아지는 문제점이 있다.
However, even if the protruding portion 111 is bent downward by heating the lower surface of the protruding portion 111 as described above, since the protruding length of the protruding portion 111 is very short and the angle of bending of the protruding portion 111 is not sufficient, There is a problem in that a step is generated at the time of welding with the upper deck 210 of the base plate 200, and the defective welding defect rate becomes very high.

도면에서와 같이 본 발명은, 제1블록(100)과 제2블록(200)의 상부에 형성되는 상갑판(110)(210)을 용접 결합하는 것으로, 상기 제1블록(100)에는 선박의 중심에 위치하는 중심격벽(120)이 포함되어 구성된다. As shown in the drawing, the upper block 100 and the upper deck 110 formed on the upper portion of the second block 200 are welded to each other. In the first block 100, And a center barrier 120 located at the center.

또한 상기 제1블록(100)의 상갑판(110)은 제2블록(200)의 상갑판(210)과의 결합을 위해 상기 중심격벽(120)의 외측으로 돌출되는 돌출부(111)를 갖도록 구성된다. The upper deck 110 of the first block 100 is configured to have a protrusion 111 protruding outward from the center partition 120 for engagement with the upper deck 210 of the second block 200.

여기서 돌출부(111)는, 제1블록(100)의 상갑판(110)과 제2블록(200)의 상갑판(210)을 용접할 경우 제1블록(100)의 중심격벽(120)이 용접에 의해 변형되거나 강도가 저하되는 것을 방지하도록 중심격벽(120)의 외측으로 돌출되도록 형성되는 것으로 그 길이는 대략 100mm 정도로 구성된다. Here, when the upper deck 110 of the first block 100 and the upper deck 210 of the second block 200 are welded, the protrusion 111 is welded to the central partition 120 of the first block 100 And is formed to protrude to the outside of the central partition 120 to prevent deformation or decrease in strength, and the length thereof is approximately 100 mm.

상기와 같이 구성되는 제1블록(100)과 제2블록(200)을 결합하기 위해서는, 중심격벽(120)의 최상단 외측 모서리 부분이 챔퍼(130) 가공된 제1블록(100)을 형성하는 제1블록 형성단계와, 상기 제1블록(100)의 중심격벽(120) 외측으로 돌출되는 상갑판(110)의 돌출부(111) 하부를 열가공하여 돌출부(111)가 하부방향으로 휘어지도록 하는 돌출부 휨 가공단계와, 상기 하부방향으로 휘어진 돌출부(111)에 제2블록(200)의 상갑판(110)을 용접 결합하는 제2블록 결합단계를 포함하여 구성된다. In order to join the first block 100 and the second block 200 constructed as described above, the uppermost outer corner of the central partition 120 is divided into a first part 100 forming the chamfered part 130, And the upper portion of the protruding portion 111 of the upper deck 110 protruding outside the central partition 120 of the first block 100 is thermally processed so that the protruding portion 111 is bent in a downward direction And a second block joining step of welding the upper deck 110 of the second block 200 to the protruding portion 111 bent in the downward direction.

상기 제1블록 형성단계는, 제1블록(100)의 제작시 중심격벽(120)의 최상단 외측 모서리 부분을 챔퍼(130) 가공한 후 상기 중심격벽(120)의 상부에 상갑판(110)을 용접결합 하는 것이다. The first block forming step may include forming a chamfer 130 on the uppermost outer corner of the central partition 120 during fabrication of the first block 100 and welding the upper deck 110 to the upper part of the central partition 120. [ Lt; / RTI >

이때 상갑판(110)은 제2블록(200)의 상갑판(210)과의 결합을 위해 상기 중심격벽(120)의 외측으로 돌출되는 돌출부(111)가 형성되도록 중심격벽(120) 상에 결합된다. At this time, the upper deck 110 is coupled to the central partition 120 such that a protrusion 111 protruding outward of the central partition 120 is formed for coupling with the upper deck 210 of the second block 200.

또한 상기와 같이 제1블록(100)의 중심격벽(120) 상부 외측면을 챔퍼(130) 가공함으로써 중심격벽(120)의 상부에 상갑판(110)을 용접하여 조립하는 과정에서 돌출부(111)가 챔퍼(130) 가공 부분에 의해 일부 휘어지게 된다. In the process of welding the upper deck 110 to the upper part of the central partition 120 by assembling the chamfer 130 on the outer side of the upper part of the central partition 120 of the first block 100, And is partially bent by the chamfer 130 processing portion.

따라서 제1블록(100)을 형성하는 과정에서 챔퍼(130) 가공 부분에 의해 돌출부(111)가 하부방향으로 일부 휘어지고 이렇게 일부 휘어진 돌출부(111)를 다시 제2블록(200)의 상갑판(210)과 용접하는 과정에서 용접하기 용이한 각도로 완전히 휘어지게 되어 단차 없이 용접이 가능하게 되는 것이다.
