Description

대형 블록 탑재를 위한 지지대 장치{Support apparatus for large size block loading}Support apparatus for large size block loading

본 고안은 대형 블록 탑재를 위한 지지대 장치에 관한 것이다. 더욱 상세하게는 대형블록을 탑재할 때 중력에 의한 구조물의 처짐을 방지하기 위한 지지구조로서 쉽게 설치하고 탑재 후 쉽게 철거가 가능하도록 하는 지지대 장치에 관한 것이다.The present invention relates to a support device for mounting a large block. More particularly, the present invention relates to a support device for easily installing and dismantling after mounting as a support structure for preventing deflection of a structure due to gravity when mounting a large block.

조선업 분야에서 한정된 도크 내에서 조선 생산량을 증가시키기 위해 다양하고 혁신적인 건조공법이 등장하고 있으며, 그 중 하나는 대형블록 탑재공법이다.In order to increase the shipbuilding production within the dock limited in the shipbuilding industry, a variety of innovative construction methods are emerging, one of which is the large block mounting method.

대형블록 탑재공법은 기존의 여러 개의 소형 블록(약 300톤)을 도크내 탑재하는 방법을 탈피하여 육상에서 건설하는 블록을 약 3000톤 규모로 최대한 크게 하여 대형 해상 크레인을 이용하여 플로팅 도크에 탑재하거나 육상의 대형 트랜스포트를 이용하여 육상 도크에 탑재하는 방식을 말한다.The large block mounting method avoids the existing method of mounting several small blocks (about 300 tons) in the dock, and builds the blocks built on land as large as approximately 3000 tons and mounts them on floating docks using large offshore cranes. It refers to a method of mounting on a land dock using a large transport on land.

이러한 대형블록 공법을 적용할 경우 선박 정도 품질, 즉 부재간 위치의 치 수 정확도 품질의 관리는 소형 블록의 탑재 공법과 비교하여 상당히 많은 계측 데이터를 다루고 있기 때문에 복잡하고 어려운 작업으로 인식되고 있다.When the large block method is applied, the management of ship quality, that is, the accuracy of the dimension accuracy of the position between members, is considered to be a complicated and difficult task because it deals with a large amount of measurement data compared to the small block mounting method.

선박 생산에서 도크내 블록 탑재를 할 때 탑재 환경의 향상과 생산성의 극대화를 위하여 실제 탑재 이전에 대응하는 두 개의 블록을 계측하고, 그 계측된 결과를 바탕으로 가상으로 블록을 조립하는 작업을 수행하여 탑재도중 발생될 수 있는 부재절단, 부재 단차 조절과 같은 재 작업을 사전에 예측하여 탑재 전에 해당 블록의 수정작업을 마무리하여 실제 탑재 시 재벌작업을 최소화하는 업무는 필수적이다.When loading blocks in docks in ship production, two blocks are measured before actual loading in order to improve the mounting environment and maximize productivity, and virtually assemble the blocks based on the measured results. It is essential to minimize the conglomerate work in actual mounting by finishing the corrective work of the block before mounting by anticipating the rework such as cutting the member and adjusting the step difference that may occur during mounting.

최근 조선 물동량의 증가로 대형블록을 육상 또는 해상에서 탑재하는 공법이 연구 개발되고 있는데, 여기에는 유압시스템이나 쐐기를 이용하여 대형블록을 탑재하였다.Recently, due to the increase in shipbuilding volume, a method of mounting a large block on land or at sea is being researched and developed. The large block is mounted using a hydraulic system or a wedge.

그러나, 상기의 유압시스템은 고가이고 쐐기는 소형블록에 적합하나, 대형블록에 적용하기에는 조정이 힘들어 부적합하다는 문제점이 있었다. However, the hydraulic system is expensive and the wedge is suitable for the small block, but there is a problem that it is difficult to adjust to apply to the large block.

이에 본 고안은 상기한 문제점을 해결하기 위한 것으로서 본 고안의 목적은 대형 구조물을 탑재할 때 구조물의 처짐을 방지/제어하기 위한 목적으로 설치가 용이하고 탑재가 완료된 후에 지지대를 쉽게 제거할 수 있는 대형블록 탑재를 위한 지지대 장치를 제공하는 데 있다.The present invention is to solve the above problems, the purpose of the present invention is to install a large structure for the purpose of preventing / controlling the deflection of the structure is easy to install and can be easily removed after the support is large The present invention provides a support device for mounting a block.

In addition, the present invention is reusable, easy to install and dismantle, and is suitable for mounting a large block.

이하, 본 고안의 실시 예에 대한 구성 및 그 작용을 첨부한 도면을 참조하면서 상세히 설명하기로 한다.Hereinafter, the configuration of the embodiment of the present invention and its operation will be described in detail with reference to the accompanying drawings.

도 1은 본 고안은 대형 블록 탑재를 위한 지지대 장치의 구성도이다.1 is a block diagram of a support device for mounting a large block of the present invention.

도 1을 살펴보면, 본 고안은 탑재되는 구조물 블록(10)의 하부에 수직으로 위치하여 1차적으로 지지하는 1차 지지대(12)가 설치되고, 상기 1차 지지대(12)의 외주를 둘러싸며, 상기 탑재되는 구조물 블록(10)의 지지 높이를 고려하여 1차 지지대 회수통(14)이 설치된다.Looking at Figure 1, the subject innovation is installed on the lower portion of the structure block 10 to be mounted vertically to support the primary support (12), and to surround the outer circumference of the primary support (12), Considering the support height of the mounted structure block 10, the primary support recovery container 14 is installed.

이때, 상기 1차 지지대 회수통(14)은 1차 지지대(12)를 지지하며, 회수하는 역할을 하게 된다.At this time, the primary support recovery container 14 supports the primary support 12, and serves to recover.

상기 1차 지지대 회수통(14) 내부에 다량의 모래(16)가 수납되며, 상기 1차 지지대(12)와 1차 지지대 회수통(14)의 연결되는 상부 절단면(17)에 용접되어 전단판(18)이 부착 설치되어 있다.A large amount of sand 16 is accommodated in the primary support recovery container 14, and a shear plate is welded to the upper cutting surface 17 connected between the primary support 12 and the primary support recovery container 14. (18) is attached.

이때, 상기 모래(16)는 1차 지지대(12)의 낙하 시 충격을 완화하는 역할을 하며, 상기 전단판(18)은 일정 높이를 조절하게 된다.At this time, the sand 16 serves to mitigate the impact when the primary support 12 falls, the front plate 18 is to adjust a certain height.

상기 1차 지지대 회수통(14) 내부의 모래(16)를 배출하기 위해 소정의 구멍이 형성되는 모래 배출구(20)가 설치되며, 상기 탑재되는 구조물 블록(10), 1차 지지대(12), 1차 지지대 회수통(14), 모래(16), 전단판(18) 및 모래 배출구(20)의 전체 구조물을 2차적으로 지지하는 2차 지지대(22)가 설치되어 있다.A sand outlet 20 having a predetermined hole is installed to discharge sand 16 in the primary support collecting container 14, and the structure block 10, the primary support 12, The secondary support 22 which secondaryly supports the whole structure of the primary support collection container 14, the sand 16, the shear plate 18, and the sand outlet 20 is provided.

이어서, 본 고안에 따른 대형 블록 탑재를 위한 지지대 장치의 설치 과정을 살펴보면 다음과 같다.Next, look at the installation process of the support device for mounting a large block according to the present invention.

먼저, 2차 지지대(22) 위에 1차 지지대 회수통(14)을 설치하고 탑재될 구조물블록(10)이 지지되는 높이를 고려하여 모래(16)를 넣는다First, the primary support recovery container 14 is installed on the secondary support 22 and the sand 16 is put in consideration of the height at which the structure block 10 to be mounted is supported.

그리고, 1차 지지대(12)를 1차 지지대 회수통(14)에 넣고 전단판(18)을 절단면(17)을 따라 용접한다.Then, the primary support 12 is placed in the primary support recovery container 14 and the shear plate 18 is welded along the cut surface 17.

다음, 상기 탑재되는 구조물 블록(10) 하부에 2차 지지대(22)를 위치시키고 구조물 블록(10)을 탑재한다.Next, the secondary support 22 is positioned below the mounted structure block 10 and the structure block 10 is mounted.

그 다음, 블록 탑재 완료 후 용접/절단면(17)을 따라 절단하면, 절단과 동시에 1차 지지대(12)는 지지력을 잃고 1차 지지대 회수통(14) 안의 모래(16)쪽으로 하중을 전달시킨다. 이 때, 상기 모래(16)는 1차 지지대(12) 낙하시 충격을 완화시킨다.Then, when the block is cut along the welding / cutting surface 17 after completion of the block mounting, the primary support 12 loses the supporting force at the same time as the cutting and transfers the load toward the sand 16 in the primary support collecting container 14. At this time, the sand 16 to mitigate the impact when the primary support 12 falls.

그리고 나서, 1차 지지대 회수통(14)의 모래 배출구(20)를 열어 모래(16)를 배출시키면서 서서히 1차 지지대(12)와 구조물 블록(10)을 분리시킨다.Then, while opening the sand outlet 20 of the primary support collecting container 14 to discharge the sand 16, the primary support 12 and the structure block 10 is gradually separated.

최종적으로, 상기 모래(16) 배출이 끝나면 1차 지지대(12)와 탑재된 구조물 블록(10)은 완전 분리됨으로써 철거 과정이 완료된다.Finally, after the discharge of the sand 16, the primary support 12 and the mounted structure block 10 are completely separated to complete the demolition process.

상술한 바와 같이, 본 고안의 바람직한 실시 예로서 대형 블록 탑재를 위한 지지대 장치에 대해 설명하였으나, 본 고안은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 기술적 범위 내에 포함된다 할 수 있다.As described above, the support device for mounting a large block as a preferred embodiment of the present invention has been described, but the present invention is not limited to the above-described specific preferred embodiment, which departs from the gist of the invention as claimed in the claims. Without this, any person having ordinary skill in the art to which the present invention pertains may make various modifications, and such changes may be included within the technical scope of the claims.
