이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 이하에 도시된 바와 같이, 본 발명에 의한 해양 구조물은 기본적으로, 콘크리트 재질에 의해 형성되고, 중공이 형성되도록 내부에 중공부재(20)가 매립된 3개 이상 복수의 기둥부재(100); 복수의 기둥부재(100)가 상호 간격을 유지하도록, 복수의 기둥부재(100) 사이에 설치됨과 아울러, 콘크리트 재질에 의해 형성되고, 중공이 형성되도록 내부에 중공부재(20)가 매립된 복수의 수평부재(200);를 포함하는 구성을 취한다.As shown in Figure 3, the marine structure according to the present invention is basically formed by a concrete material, three or more plurality of pillar members 100 having a hollow member 20 embedded therein to form a hollow is formed. ; A plurality of pillar members 100 are installed between the plurality of pillar members 100 so as to maintain a mutual gap, and are formed of a concrete material, and a plurality of hollow members 20 embedded therein to form a hollow. It takes a configuration that includes; horizontal member (200).

여기서, 중공부재(120)는 고강도이면서 중량이 작은 재질인 강재 또는 합성수지 재질(FRP 등)에 의해 형성되는 것이 좋다. Here, the hollow member 120 is preferably made of steel or synthetic resin material (FRP, etc.) of high strength and small weight.

즉, 본 발명에 의한 해양 구조물은 콘크리트의 타설에 의해 기둥부재(100), 수평부재(200)를 형성할 때, 상술한 중공부재(20)를 거푸집 내부에 설치하여 내부 거푸집 역할을 하도록 함과 아울러, 콘크리트의 경화 후에는 내부의 중공부재(20)가 콘크리트와 일체로 형성되어 구조체 역할을 하도록 한 것이다.That is, in the offshore structure according to the present invention, when the pillar member 100 and the horizontal member 200 are formed by placing concrete, the hollow member 20 is installed inside the formwork to serve as an internal formwork. In addition, after curing of the concrete, the hollow member 20 is formed integrally with the concrete to serve as a structure.

이와 같이 콘크리트 내부에 설치된 중공부재(20)는 주위의 콘크리트에 의해 모든 부위가 구속되므로, 그 구속효과(콤파운드 효과)로 인하여 강도가 대단히 상승하는바, 휨 또는 전단 변형이 발생하기 어려운 우수한 압축부재가 되어, 전체적으로 콘크리트 부재의 구조적 안정성을 증대시키는 효율적인 구조를 얻을 수 있다.Since the hollow member 20 installed inside the concrete is constrained to all parts by the surrounding concrete, the strength is greatly increased due to the restraining effect (compound effect), and thus an excellent compression member is hard to bend or shear deformation. In this way, an efficient structure for increasing the structural stability of the concrete member as a whole can be obtained.

또한, 그 중공부재(20)가 차지하는 공간만큼 콘크리트의 양이 줄게 되므로, 당연히 콘크리트 부재 전체의 중량은 줄어든다.In addition, since the amount of concrete is reduced by the space occupied by the hollow member 20, the weight of the entire concrete member is naturally reduced.

따라서 자중이 작으면서도 강도가 우수한 콘크리트 부재를 얻을 수 있으므로, 단면의 크기를 축소할 수 있는바, 콘크리트에 의해 형성된 기둥부재, 수평부재의 자중을 줄일 수 있어, 지상에서 제조된 해양 구조물을 해중에 용이하게 인양하여 시공할 수 있다는 장점이 있다.Therefore, it is possible to obtain a concrete member having low strength and excellent strength, so that the size of the cross section can be reduced, and the self-weight of the pillar member and the horizontal member formed by the concrete can be reduced. There is an advantage that it can be easily lifted and constructed.

기둥부재(100)의 하단에 심부의 파일 장착공(111)이 형성된 파일장착부(110)가 형성된 구성을 취하는 경우, 다음과 같은 방식에 의해 시공할 수 있다.When taking the configuration in which the pile mounting portion 110 in which the pile mounting hole 111 is formed at the lower end of the pillar member 100, it can be constructed by the following method.

지상에서 기둥부재(100) 및 수평부재(200)를 결합하여 해양 구조물을 제조한다.Combine the pillar member 100 and the horizontal member 200 from the ground to produce a marine structure.

해상 크레인을 이용하여 위 해양 구조물을 인양하여, 기둥부재(100)의 파일장착부(110)가 해저면에 접촉하도록, 해양 구조물을 해중에 설치한다.By lifting the above-mentioned offshore structure using a marine crane, the offshore structure is installed in the sea so that the pile mounting portion 110 of the pillar member 100 contacts the sea bottom.

이후, 파일장착부(110)의 파일 장착공(111)에 파일(112)을 장착하여, 파일(112)의 하단이 해저지반에 매설되도록 한다(도 14).Subsequently, the pile 112 is mounted in the pile mounting hole 111 of the pile mounting unit 110 so that the lower end of the pile 112 is embedded in the seabed (FIG. 14).

즉, 해상에서 해양 구조물의 제조 및 시공이 이루어지는 것이 아니라, 해양 구조물의 제조를 지상에서 이루어지도록 하고, 이를 시공위치로 인양하여 파일장착부(110)에 파일(112)을 항타 등에 의해 설치하는 방식에 의해 시공하도록 한 것이다.That is, the manufacturing and construction of the offshore structure is not carried out at sea, but the manufacture of the offshore structure is to be made on the ground, and lifted it to the construction position to install the pile 112 on the pile mounting part 110 by driving, etc. By construction.

따라서 제조 및 시공을 위하여 과도한 수고, 비용이 소요되지 않으면서도, 충분한 구조적 안전성을 얻는다는 효과가 있다.Therefore, there is an effect of obtaining sufficient structural safety without excessive labor and cost for manufacturing and construction.

본 발명에 의한 해양 구조물은 이에 풍력 발전 설비를 설치함으로써 해상 풍력발전 구조물을 형성할 수 있고, 기타 일반적인 해양 구조물에 대하여도 범용적으로 적용할 수 있다.The offshore structure according to the present invention may form an offshore wind power structure by installing a wind power installation therein, and may be universally applied to other general offshore structures.

중공부재(20)는 속이 비고 모든 면이 폐쇄된 구조이면, 어떠한 구조를 취하더라도 관계없으나, 콘크리트 부재(100)의 형상과 동일한 형상의 구조(규격만 축소된 구조)를 취하도록 하여 본체 콘크리트의 두께를 일정하게 하는 것이 구조역학적으로 유리하다(도 6).As long as the hollow member 20 is hollow and all surfaces are closed, it may be any structure, but the hollow member 20 may have a structure having the same shape as that of the concrete member 100 (only a reduced structure). It is structurally advantageous to make the thickness constant (FIG. 6).

중공부재(20)의 설치로 인하여 기둥부재(100), 수평부재(200)의 단면이 축소됨에 따른 강도 감소를 보상하기 위하여, 기둥부재(100), 수평부재(200)에는 프리텐션 방식(프리캐스트)에 의해 긴장재(10)가 긴장된 상태로 매설된 구성을 취하는 것이 바람직하다(도 5,7).Due to the installation of the hollow member 20, the pillar member 100 and the horizontal member 200 are pretensioned (free) in order to compensate for the decrease in strength due to the reduction of the cross section of the pillar member 100 and the horizontal member 200. It is preferable to take the structure in which the tension member 10 is buried in a tensioned state by the cast) (FIGS. 5 and 7).

기둥부재(100)와 수평부재(200)의 안정적인 결합을 위하여, 결합부재(201)가 수평부재(200)의 내부 중공부재(20)에 결합하고, 이 결합부재(201)에 의해 위 기둥부재(100)와의 결합이 이루어지도록 하는 구성을 취하는 것이 바람직하다.For the stable coupling of the pillar member 100 and the horizontal member 200, the coupling member 201 is coupled to the inner hollow member 20 of the horizontal member 200, the upper member by the coupling member 201 It is preferable to take a configuration such that the coupling with the (100) is made.

즉, 결합부재(201)의 일단이 중공부재(20)의 일단 또는 양단에 결합하고, 결합부재(201)의 타단은 수평부재(200)의 외측으로 노출된 구성이 그것이다(도 7).That is, one end of the coupling member 201 is coupled to one end or both ends of the hollow member 20, and the other end of the coupling member 201 is exposed to the outside of the horizontal member 200 (Fig. 7).

이러한 결합부재(201)로는 강봉, 강선 등을 적용할 수 있으며, 이 결합부재(201)가 프리텐션 방식에 의해 긴장된 상태로 수평부재(200)에 매설되는 경우(결합부재가 긴장재로 사용된 경우), 단면축소효과를 더욱 크게 얻을 수 있다.Steel bar, steel wire, etc. may be applied to the coupling member 201, and the coupling member 201 is embedded in the horizontal member 200 in a tensioned state by a pretension method (when the coupling member is used as a tension member). ), It is possible to obtain a larger cross-sectional reduction effect.

기둥부재(100)의 길이가 긴 경우, 기둥부재(100)에는 중공부재(20) 복수가 길이방향을 따라 간격을 두고 매설되는 것이 좋은데, 이때 복수의 중공부재(20)는 강봉, 강선 등의 상호 연결부(21)에 의해 결합하도록 하는 것이 바람직하다(도 5).When the length of the pillar member 100 is long, it is preferable that a plurality of hollow members 20 are embedded in the pillar member 100 at intervals along the longitudinal direction, wherein the plurality of hollow members 20 are steel bars, steel wires, or the like. It is preferred to engage by interconnect 21 (FIG. 5).

기둥부재(100)에 긴장재(10)를 설치하는 방식은 프리텐션 방식을 적용하는 것이 바람직하고, 기둥부재(100)에 수평부재(200)를 설치하는 방식은 상술한 바와 같은 포스트텐션 방식을 적용하는 것이 바람직하다.In the method of installing the tension member 10 in the pillar member 100, it is preferable to apply a pretension method, and in the method of installing the horizontal member 200 in the pillar member 100, the post tension method as described above is applied. It is desirable to.

다만, 수평부재(200)의 강도를 보다 크게 얻고자 하는 경우에는, 일단 프리텐션 방식에 의해 긴장재(10)가 장착된 수평부재(200)를 제조하고, 이러한 수평부재(200)를 포스트텐션 방식에 의해 기둥부재(100)에 장착하는 것이 더욱 바람직하다(도 7,9).However, when the strength of the horizontal member 200 is to be obtained more, the horizontal member 200 to which the tension member 10 is mounted is manufactured by the pretension method, and the horizontal member 200 is post tensioned. It is more preferable to attach to the pillar member 100 by (FIG. 7,9).

기둥부재(100)의 일측면에 수평부재(200)의 단부가 결합하기 위한 결합홈(120)이 형성되고, 결합홈(120)에 위 결합부재(201)가 관통하도록 결합부재 관통공(121)이 형성된 구조를 취하는 경우, 수평부재(200)를 기둥부재(100)의 결합홈(120)에 결합한 상태에서 결합부재 관통공(121)을 통해 결합부재(201)의 프리스트레싱 및 정착작업을 할 수 있으므로, 효율적인 작업이 가능하다는 효과가 있다(도 8).A coupling groove 120 is formed on one side of the pillar member 100 to couple an end of the horizontal member 200 to the coupling member 120 so that the coupling member 201 penetrates the coupling groove 120. When the structure is formed, the pre-stressing and fixing of the coupling member 201 through the coupling member through hole 121 in the state in which the horizontal member 200 is coupled to the coupling groove 120 of the pillar member 100. As a result, efficient work is possible (FIG. 8).

여기서, 결합부재 관통공(121)은 상술한 중간부재(20)의 연결부(21)가 형성된 영역에 형성되는 것이 구조적 안정성을 위하여 바람직하다(도 8).Here, the coupling member through hole 121 is preferably formed in the region where the connection portion 21 of the intermediate member 20 is formed for structural stability (FIG. 8).

기둥부재(100)의 타측면에 결합부재 관통공(121)을 관통하여 설치된 결합부재(201)의 단부는 콘크리트 재질의 기둥부재(100)에 직접 정착될 수도 있으나, 강판 등에 의한 별도의 정착부재(210)를 설치하고 이에 결합부재(201)의 단부가 정착되도록 하는 것이 구조적 안정성 측면에서 더욱 바람직하다(도 9).The end of the coupling member 201 installed through the coupling member through-hole 121 on the other side of the pillar member 100 may be directly fixed to the pillar member 100 made of concrete, but is a separate fixing member by a steel plate or the like. It is more preferable in terms of structural stability to install 210 and allow the end of the coupling member 201 to be fixed thereto (FIG. 9).

이러한 정착부재(210)가 설치되도록 기둥부재(100)의 타측면에 설치홈(130)이 형성되는 경우, 긴장재(10)의 단부가 정착된 상태에서 그 설치홈(130)에 방수부재(211) 등을 설치하여 밀폐구조를 쉽게 이룰 수 있다는 장점이 있다(도 9).When the installation groove 130 is formed on the other side of the pillar member 100 so that the fixing member 210 is installed, the waterproof member 211 in the installation groove 130 in the state in which the end of the tension member 10 is fixed There is an advantage that can easily achieve a sealed structure by installing () (Fig. 9).

기둥부재(100)와 수평부재(200)의 결합부에는 응력집중이 발생하게 되는데, 이러한 부위를 보호하기 위해서는, 기둥부재(100)를 덮어 보호하도록, 심부에 기둥부재(100)의 수용공간이 형성된 기둥부재 보호부(410); 복수의 수평부재(200)의 단부를 덮어 보호하도록, 기둥부재 보호부(410)에서 측방으로 연장형성된 복수의 수평부재 보호부(420);를 포함하는 보호부재(400)를 더 구비한 구성을 취하는 것이 바람직하다(도 10).Stress concentration occurs in the coupling portion of the pillar member 100 and the horizontal member 200. In order to protect the portion, the receiving space of the pillar member 100 is provided at the core portion to cover and protect the pillar member 100. A pillar member protection part 410 formed; The protection member 400 further includes a plurality of horizontal member protection parts 420 extending laterally from the pillar member protection part 410 to cover and protect the ends of the plurality of horizontal members 200. It is desirable to take (FIG. 10).

수평부재 보호부(420)의 반대측에는 기둥부재(100)에 대한 결합부재(201)의 단부의 결합작업(긴장 및 정착)을 위한 작업공(411)이 형성되는 것이 작업의 효율성을 위하여 바람직하다(도 11).On the opposite side of the horizontal member protection portion 420, it is preferable for the efficiency of the work to be formed a work hole 411 for the coupling work (tension and fixing) of the end of the coupling member 201 to the pillar member 100. (FIG. 11).

기둥부재(100)와 수평부재(200)만으로 원하는 강도를 얻을 수 없는 경우, 복수의 수평부재(200)의 단부에 사선방향으로 결합하는 경사부재(300)를 더 구비한 구조를 취할 수 있다.If the desired strength cannot be obtained with only the pillar member 100 and the horizontal member 200, the structure may further include an inclined member 300 coupled to the ends of the plurality of horizontal members 200 in an oblique direction.

이러한 경사부재(300)는 강재를 적용할 수도 있고, 상술한 수평부재(200)와 같은 프리스트레스트 콘크리트 방식을 적용할 수도 있다.The inclined member 300 may be applied to steel, or may be applied to the prestressed concrete method such as the horizontal member 200 described above.

기둥부재(100)는 3개 이상의 복수가 설치되어 해양 구조물 전체의 종단면이 삼각형, 사각형 등인 구조를 취하게 되는데, 이러한 복수의 기둥부재(100)는 상측의 간격에 비해 하측의 간격이 넓도록 설치되는 것이 구조적 안정성 측면에서 바람직하다.The pillar member 100 has a plurality of three or more are installed to take a structure in which the longitudinal cross-section of the entire marine structure is a triangle, a square, etc., such a plurality of pillar members 100 are installed so that the lower interval is wider than the upper interval. It is preferable in terms of structural stability.

2개의 기둥부재(100)를 상호 간격을 두고 배치하고, 그 사이에 복수의 수평부재(200)를 설치하여 제1 조립체(A)를 형성하고, 동일한 방식에 의해 제2 조립체(B)를 형성한다(도 12).The two pillar members 100 are arranged at a distance from each other, and a plurality of horizontal members 200 are installed therebetween to form the first assembly A, and the second assembly B is formed in the same manner. (FIG. 12).

제1 조립체(A)와 제2 조립체(B)가 누운 상태에서 횡방향으로 마주보도록 상호 간격을 두고 배치하고, 그 사이에 수평부재(200)를 설치한다(도 13).In a state where the first assembly A and the second assembly B are laid down, they are arranged at intervals to face each other in a horizontal direction, and a horizontal member 200 is provided therebetween (FIG. 13).
