본 발명은 액화천연가스 저장탱크의 보강용 콘크리트 블록 연결구조체에 관한 것으로, 특히 액화천연가스 저장탱크의 내조 하부에 환형으로 배치되는 보강용 콘크리트 블록을 공장에서 미리 조립식 블록 형태로 제작한 후에 내조탱크의 하측에서 서로 인접된 보강용 콘크리트 블록들을 간편하게 연결할 수 있도록 그 구조가 개선된 액화천연가스 저장탱크의 보강용 콘크리트 블록 연결구조체에 관한 것이다.The present invention relates to a concrete block connection structure for reinforcing a liquefied natural gas storage tank, and in particular, a reinforcing concrete block arranged in an annular shape under the inner tank of a liquefied natural gas storage tank in a factory in advance in the form of a prefabricated block, and then an internal tank It relates to a concrete block connection structure for reinforcement of a liquefied natural gas storage tank with an improved structure so that adjacent reinforcing concrete blocks can be easily connected to each other at the lower side of the liquefied natural gas storage tank.

일반적으로, 천연가스는 메탄을 주성분으로 하고, 소량의 에탄, 프로판 등을 포함하는 화석연료로서, 최근 다양한 기술 분야에 저공해 에너지원으로 각광받고 있다. 운전과 저장의 편의를 위해 영하 162로 압축, 냉각, 액화시켜 부피를 1/600으로 줄인 것을 액화천연가스라고 한다.In general, natural gas is a fossil fuel containing methane as a main component and a small amount of ethane, propane, etc., and has recently been spotlighted as a low-emission energy source in various technical fields. For convenience of operation and storage, the volume is reduced to 1/600 by compressing, cooling, and liquefying to minus 162, which is called liquefied natural gas.

액화천연가스 저장탱크는 대부분 완전 방호식 저장탱크 (Full containment Tank)로 만들어지며 완전 방호식 저장탱크는 콘크리트로 된 외조탱크와 9% 니켈 재질의 내조탱크로 구성되어 있고, 내조탱크에는 -162도의 LNG를 저장한다. 외조탱크와 내조탱크 사이에는 증발가스 (BOG: Boil of gas)을 줄이기 위한 단열시스템을 설치한다. 단열시스템은 벽 단열재, 현수천정 단열재, 바닥 단열재로 나눠지며 LNG 저장탱크의 성능보증을 위해 가장 중요한 시스템으로 고려되어 진다. 내조탱크 기계공사는 바닥 단열재 설치가 되어야 후 공정이 진행될 수 있는 주 공정 (Critical Path)으로 구분된다.Liquefied natural gas storage tanks are mostly made of full containment tanks. Fully protected storage tanks consist of an outer tank made of concrete and an inner tank made of 9% nickel. Save LNG. An insulation system is installed between the outer tank and the inner tank to reduce boil of gas (BOG). The insulation system is divided into wall insulation, suspension ceiling insulation, and floor insulation, and is considered as the most important system to guarantee the performance of LNG storage tanks. The internal tank mechanical work is divided into the main process (Critical Path) in which the process can proceed after the floor insulation has been installed.

The reinforcing concrete block 100 has a trapezoidal cross-sectional structure that is installed in an annular shape at a lower portion around the rim of the shell plate of the inner tank and has an outer side length longer than an inner side.

상기한 보강용 콘크리트 블록은 일체형으로 구성할 경우에는 현장에서 직접 거푸집을 제작한 후에 철근을 조립하고 콘크리트를 타설 및 양생하는 방법이 있으나, 이 경우에는 거푸집 설치공간을 확보하기가 어렵고 콘크리트의 타설 및 양생하는 작업시간이 오래 걸리게 되어 공사기간이 오래 걸리는 단점이 있다.When the above-described reinforcing concrete block is configured as an integral type, there is a method of assembling reinforcing bars and pouring and curing concrete after making the formwork directly on site, but in this case, it is difficult to secure a space for installing the formwork, and There is a disadvantage that it takes a long time to cure, so that the construction period takes a long time.

A rod member 200 inserted horizontally into the pipe member 150 and having male threads formed at the upper and lower ends of the pipe member 150;
The inner and outer sides of the rod member 200 are coupled to each pass through, and the inner side of the reinforcing concrete block 100 adjacent to each other among the reinforcing concrete blocks 100 and the reinforcing concrete block 100 adjacent to each other. Washer plates 300 respectively connecting the outside; And
Consists of; a fastening nut 400 that is screwed to the upper and lower ends of the rod member 200
Become,
The reinforced concrete block 100 is a reinforced concrete block having a trapezoidal cross-sectional structure in which the length of the outer side is greater than the length of the inner side,
The washer plate 300 is formed of a rectangular plate having a length corresponding to the interval between the pipe members 150 of the reinforcing concrete block 100 adjacent to each other,
The washer plate 300 has a structure in which coupling holes are formed at left and right ends so that the ends of the rod member 200 pass through, and the rod member 200 is formed in a round bar shape,
As the reinforcing concrete blocks 100 adjacent to each other through the washer plate 300 and the rod member 200 and the fastening nut 400 are integrally connected in an annular shape, the lower side of the outer circumference of the inner tank of the storage tank is supported. As a result, a concrete block connection structure for reinforcement of a liquefied natural gas storage tank, characterized in that it is possible to perform the construction work of the reinforcing concrete block 100 easily and shorten the construction period. 삭제delete 삭제delete
