본 발명은 강판콘크리트 구조와 이질 구조간의 접합 방법에 관한 것으로서, 더욱 상세하게는 강판콘크리트 구조와 접합되는 이질의 콘크리트 구조의 일부에 접합용 강판을 먼저 설치함으로써 이질의 콘크리트 구조에 후속하여 접합되는 강판콘크리트 구조와의 일체성 및 시공성을 확보하여 접합면에서의 응력 저하없이 하중이 연속적이고 균등하게 전달되도록 함으로써 강판콘크리트 구조와 이질의 콘크리트 구조간의 접합성능을 향상시킬 수 있는 강판콘크리트 구조와 이질 구조간의 접합 방법에 관한 것이다.The present invention relates to a method of joining between a steel plate concrete structure and a heterogeneous structure, and more particularly, a steel plate that is subsequently joined to a heterogeneous concrete structure by first installing a joining steel sheet in a part of the heterogeneous concrete structure joined to the steel plate concrete structure. It ensures the integrity and workability of the concrete structure so that the load is continuously and evenly transmitted without deteriorating the stress at the joint surface, thereby improving the bonding performance between the steel plate concrete structure and the heterogeneous concrete structure. It is about a joining method.
종래 구조물의 벽체 시공 방법에는 철근콘크리트 구조(RC; Reinforced Concrete), 철골철근콘크리트 구조(SRC; Steel framed Reinforced Concrete), 강판콘크리트 구조(SC; Steel plate Concrete)에 의한 시공 방법이 있다.Wall construction methods of conventional structures include a reinforced concrete structure (RC; Reinforced Concrete), steel reinforced concrete structure (SRC; Steel framed Reinforced Concrete), steel plate concrete (SC; steel plate concrete).
상기 철근콘크리트 구조(RC)는 콘크리트의 압축력과 철근의 인장력이 일체로 되어 서로의 결점을 보완한 구조이고, 철골철근콘크리트 구조(SRC)는 철골 뼈대를 철근콘크리트로 피복하고 보강한 구조로서, 외력은 철골이 부담하고 그 주위를 둘러싼 철근콘크리트는 화재시에 철골을 피복 및 보강할 수 있도록 구성된 것이다.The reinforced concrete structure (RC) is a structure in which the compressive force of the concrete and the tensile force of the reinforcing bars are complemented to each other, and the steel reinforced concrete structure (SRC) is a structure in which the steel frame is covered with reinforced concrete and reinforced, Reinforced concrete that is covered by the steel frame and surrounding it is configured to cover and reinforce the steel frame in case of fire.
상기 철근콘크리트 구조(RC)와 철골철근콘크리트 구조(SRC)는 현장에서 거푸집과 철근이나 철골 등을 직접 조립하고 콘크리트를 타설하여 구조물을 시공하게 되므로 공사 기간이 길어지는 단점이 있었다.The reinforced concrete structure (RC) and the steel reinforced concrete structure (SRC) has a disadvantage in that the construction period is long because direct construction of the formwork and reinforcing steel or steel frame and constructing the structure by pouring concrete.
이러한 문제를 보완할 수 있도록 개발된 강판콘크리트 구조(SC)는 대향하는 한 쌍의 강판 내측에 콘크리트를 충전하고, 콘크리트와 강판이 일체화되도록 강판의 내벽에 다수의 스터드(Stud)를 돌출 형성함과 동시에 강판 사이의 간격이 일정하게 유지되도록 강판의 내벽에 타이 바(Tie bar)의 양단이 결합된 구조로 이루어져 있다.The steel plate concrete structure (SC), which is developed to solve this problem, fills concrete inside a pair of opposing steel plates, and protrudes a plurality of studs on the inner wall of the steel plate so that the concrete and the steel plate are integrated. At the same time, it consists of a structure in which both ends of a tie bar are coupled to the inner wall of the steel sheet so that the gap between the steel sheets is kept constant.
종래에는 구조물의 벽체 시공시 철근콘크리트 구조(RC), 철골철근콘크리트 구조(SRC), 강판콘크리트 구조(SC)의 각 동종 구조간의 접합 기술이 사용되고 있다. 철근콘크리트 구조(RC) 및 철골철근콘크리트 구조(SRC)에서의 동종 구조간의 벽체 접합 방법은, 벽체 내부에 철근 또는 철골을 설치하고 콘크리트를 타설함으로써 접합이 이루어지게 된다. 즉, 동종 구조간의 벽체 접합(연결) 부분에 특별한 접합 기술이 요구되는 것은 아니며, 단지 설계 및 시공 필요에 따라 접합면이 발생하게 된다. 이를 첨부된 도면을 참조하여 설명한다.Conventionally, the joining technique between the same type of reinforced concrete structure (RC), steel reinforced concrete structure (SRC), steel plate concrete structure (SC) is used in the construction of the wall of the structure. Wall joining method between homogeneous structures in reinforced concrete structure (RC) and steel reinforced concrete structure (SRC) is made by installing reinforcing steel or steel frame inside the wall and pouring concrete. In other words, no special joining technique is required for wall joining (joint) parts between homogeneous structures, but only joining surfaces are generated depending on the design and construction needs. This will be described with reference to the accompanying drawings.
도 1과 도 2는 종래 철근콘크리트 구조의 벽체간 수직 접합의 종단면도로서, 도 1은 슬래브가 없는 경우, 도 2는 슬래브가 있는 경우의 종단면도이다.1 and 2 is a longitudinal cross-sectional view of the vertical joint between the walls of the conventional reinforced concrete structure, Figure 1 is a longitudinal cross-sectional view when there is no slab, Figure 2 when there is a slab.
종래 철근콘크리트 구조의 벽체 접합 방법은, 도 1에 도시된 바와 같이 하부 철근콘크리트 구조(10)를 완성한 후, 그 상부에 동종 구조의 상부 철근콘크리트 구조(20)가 접합된 것으로, 먼저 수직 철근(11)과 수평 철근(12)이 결합된 철근 구조물에 콘크리트(13)를 타설하여 하부 철근콘크리트 구조(10)를 형성하고, 콘크리트(13) 상단의 접합면(15)의 상측으로 돌출되도록 설치된 수직 철근(11)에 수직 철근(21)의 하단 일부를 결합하고 수직 철근(21)에 수평 철근(22)을 결합시킨 철근 구조물에 콘크리트(23)를 타설하여 상부 철근콘크리트 구조(20)를 형성함으로써 벽체 구조물을 시공하게 된다.Conventional reinforced concrete wall joining method, as shown in Figure 1, after completing the bottom reinforced concrete structure 10, the upper reinforced concrete structure 20 of the same type is bonded to the upper, first reinforcement ( 11) the concrete 13 is poured into the reinforcing steel structure combined with the horizontal reinforcing bar 12 to form a lower reinforced concrete structure 10, and is vertically installed to protrude upward from the joint surface 15 of the upper end of the concrete 13 By joining a portion of the lower end of the vertical reinforcing bar 21 to the reinforcing bar 11 and placing the concrete 23 on the reinforcing bar structure that combines the horizontal reinforcing bar 22 to the vertical reinforcing bar 21 to form the upper reinforced concrete structure 20 You will build a wall structure.
또 다른 경우로는, 도 2에 도시된 바와 같이 하부 철근콘크리트 구조(10)의 일측으로 슬래브 철근(31)과 수평 철근(32)이 결합된 철근 구조물에 콘크리트(33)를 타설하여 슬래브 철근콘크리트(30) 구조를 연결시켜 벽체 구조물을 시공하게 된다.In another case, as shown in FIG. 2, the slab reinforced concrete is poured into the reinforcing structure in which the slab reinforcement 31 and the horizontal reinforcement 32 are coupled to one side of the lower reinforcement concrete structure 10. (30) The construction of the wall structure by connecting the structure.
상기와 같이 종래의 구조인 철근콘크리트 구조(RC), 철골철근콘크리트 구조(SRC)는 공사기간의 단축에 한계가 있고, 새로운 구조라 할 수 있는 강판콘크리트 구조(SC)는 거푸집 해체와 철근 설치 작업 등이 생략되므로 공사기간이 단축되어 사용성이 커지고 있으나, 공기단축에 유리한 강판콘크리트 구조(SC)의 확대 적용을 위해서는 철근콘크리트 구조(RC)와의 접합기술이 필요하다. Reinforced concrete structure (RC), steel reinforced concrete structure (SRC), which is a conventional structure as described above, has a limitation in shortening the construction period, and the steel plate concrete structure (SC), which can be called a new structure, dismantles formwork and installs reinforcing bars. Since the construction period is shortened so that the usability is increased, the bonding technology with the reinforced concrete structure (RC) is required for the expanded application of the steel plate concrete structure (SC), which is advantageous for shortening the air.
그러나 종래에는 동종 구조간의 접합기술만을 적용하고 있을 뿐이며, 강판콘크리트 구조(SC)와 철근콘크리트 구조(RC) 또는 철골철근콘크리트 구조(SRC)와 같이 서로 다른 구조간의 접합기술의 개발이 미비하여, 접합면에서의 응력 저하가 발생하고 하중이 연속적으로 균등하게 전달되지 못하여 벽체 구조물이 취약해지는 문제점이 있었다. However, conventionally, only the bonding technology between homogeneous structures is applied, and the development of bonding technology between different structures such as steel plate concrete structure (SC) and reinforced concrete structure (RC) or steel reinforced concrete structure (SRC) is insufficient. Deterioration of the stress occurs in the plane and there is a problem that the wall structure is vulnerable because the load is not transmitted evenly continuously.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 강판콘크리트 구조(SC)와 이질 구조간의 접합시 접합면에서의 응력 저하를 방지하고 벽체 구조물에 하중이 연속적이고 균등하게 전달되도록 함으로써 강판콘크리트 구조와 이질 구조간의 접합성능을 향상시킬 수 있는 강판콘크리트 구조와 이질 구조간의 접합 방법을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, the steel sheet concrete by preventing the stress degradation at the joint surface when the steel plate concrete structure (SC) and the heterogeneous structure is bonded and the load is continuously and evenly transmitted to the wall structure An object of the present invention is to provide a joining method between a steel plate concrete structure and a heterogeneous structure that can improve the bonding performance between the structure and the heterogeneous structure.
