본 발명은 종늑골의 응력집중을 완화시키는 선박의 스켈롭에 관한 것으로, 더 상세하게는 선박의 종늑골의 응력집중을 완화시켜 종늑골의 피로강도를 증대시키는 전도 방지 브라케트에 시공되는 새로운 형태의 스켈롭에 관한 것이다.
The present invention relates to a ship's skellop to alleviate the stress concentration of the longitudinal ribs, and more particularly to a new form to be installed in the fall prevention bracket to reduce the stress concentration of the longitudinal ribs of the ship to increase the fatigue strength of the longitudinal ribs It's about the skelp.

통상, 스켈롭은 구조물의 내부재가 서로 교차되어 용접될 때 용접선이 진행될 수 있도록 하기 위해 뚫은 반원형 모양의 작은 구멍으로 부재의 두께에 따라 반경이 달라지는데, 종래의 선박의 구조 설계 시 늑판의 전도 방지를 위하여 늑골 면재에 설치하는 전도 방지 브라케트에 의하여 종늑골에 응력 집중 현상에 따른 피로 균열이 쉽게 발생하고, 전도 방지 브라케트에 시공된 스켈롭의 크기가 작아서(통상 반경 100mm 미만) 용접 등의 가공작업이 어려운 문제점이 있었다.
In general, the skellop is a semi-circular small hole drilled to allow the welding line to proceed when the inner parts of the structure cross each other and are welded, and the radius varies according to the thickness of the member. In order to prevent fatigue cracking due to stress concentration on longitudinal ribs due to the fall prevention bracket installed on the rib face, the size of the scallop installed on the fall prevention bracket is small (usually less than 100mm). The work was difficult.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출되는 것으로, 스켈롭의 형상을 변화시켜 응력 집중부의 응력 집중현상을 감소시켜 피로수명을 증대시키고, 작업공간을 확대시켜 용접 등의 가공작업의 편리성을 증대시키는 선박의 스켈롭을 제공함을 목적으로 한다.
The present invention is devised to solve the conventional problems as described above, by changing the shape of the skelp to reduce the stress concentration of the stress concentration portion to increase the fatigue life, to enlarge the working space of the machining work such as welding It is an object of the present invention to provide a skelp of a ship that increases convenience.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명은 늑판 전도 방지 브라케트에 설치되어 있는 스켈롭의 크기를 수평 늑판 방요재를 위해 시공되어 있는 구멍(슬로트)까지 확장함으로서 구속력의 감소로 인하여 응력집중 현상이 완화되고 궁극적으로 종늑골의 피로강도가 증대되는 것이다.
The present invention to achieve the object as described above and to solve the problems of the prior art is the hole (slot) which is constructed for the horizontal floor insulation material of the size of the scallop installed in the floor fall prevention bracket By expanding to, the stress concentration is alleviated due to the reduction of restraint force and ultimately the fatigue strength of longitudinal rib is increased.

본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.Referring to the configuration and the operation of the embodiment of the present invention in detail with reference to the accompanying drawings as follows.

도 1 은 수평 늑판 방요재가 설치된 선박 늑판의 정·측면도이고, 도 2 는 수직 늑판 방요재가 설치된 선박 늑판의 정·측면도이며, 도 3 은 도1,2의 기존 스켈롭 상세도이고, 도 4 는 본 발명에 따른 도1,2의 스켈롭 상세도로서,1 is a front and side view of a ship floor with a horizontal floor insulation installed, Figure 2 is a front and side view of a ship floor with a vertical floor insulation installed, Figure 3 is a detailed view of the existing scallop of Figures 1 and 2, Figure 4 As a detail view of the skelp of Figs.

본 발명은 선박의 늑판(10)과 종늑골(20)의 교차부위에 늑판의 전도를 방지하기 위하여 설치된 브라케트(30)에 시공된 스켈롭(40)에 있어서,In the present invention, in the scallop (40) constructed in the bracket 30 is installed in order to prevent the fall of the floor at the intersection of the floor 10 and the longitudinal rib 20 of the ship,

상기 스켈롭(40)은 수평 늑판 방요재(50)를 위해 늑판에 시공되는 구멍까지 크기를 확장하고 유연부(60)를 추가하여 구성되며, 수평 늑판 방요재가 없는 늑판의 경우도 크기를 확장시키고 유연부(60)를 추가하여 구성되는 것이다.The scallop 40 is configured to expand the size up to the hole to be installed in the floor for the horizontal floor board 50, and add a flexible part 60, even in the case of the floor without horizontal floor board It is comprised by adding the flexible part 60.

여기서 상기 스켈롭(40)의 가로(a) 세로(b)의 크기는 150mm 이상으로 형성된다.In this case, the size of the width (a) and length (b) of the snippet 40 is formed to be 150mm or more.

상기와 같이 본 발명은 늑판 전도 방지 브라케트에 설치되어 있는 스켈롭의 크기를 수평 늑판 방요재를 위해 시공되어 있는 구멍(슬로트)까지 확장하고, 종늑골과 부착되는 부위 끝단에 유연부(소프트 토우)가 시공되는 것이다.(도4)As described above, the present invention extends the size of the skelop installed in the floor fall prevention bracket to the hole (slot) constructed for the horizontal floor insulation material, and the flexible part (soft) at the end of the portion attached to the longitudinal ribs. Toe) is constructed (Fig. 4).

종늑골에 발생하는 피로균열의 주요한 원인인 응력집중 현상은 늑판에 의한 구속력에 기인하는데, 본 발명에 의한 새로운 형태의 스켈롭은 전도 방지 브라케트와 종늑골의 접합 길이를 감소시켜 접합부 주위 부재를 유연화시켜 구속력을 감소시키게 되는 것이다.
The stress concentration phenomenon, which is the main cause of fatigue cracking in the longitudinal ribs, is due to the restraint by the floor plate. The new type of skelp reduces the joint length between the fall prevention bracket and the longitudinal ribs. Flexibility reduces the binding force.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.

상기와 같이 구성된 본 발명은 구속력의 감소로 인하여 응력집중 현상이 완화되고 궁극적으로 종늑골의 피로수명이 증가되며, 스켈롭의 구멍크기가 넓어짐으로 하여 작업의 편리성이 증가되어 선박 건조공수가 감소되고 상대적으로 적은 양이지만 재료비나 선박의 중량 역시 감소될 수 있는 유용한 발명이다.


According to the present invention configured as described above, the stress concentration is alleviated due to the reduction of the restraint force, and ultimately, the fatigue life of the longitudinal rib is increased, and the convenience of the operation is increased due to the widening of the hole size of the scallop. Although it is a relatively small amount, the material cost and the weight of the ship are also useful inventions that can be reduced.
