강판전단벽{Steel plate shear wall}Steel plate shear wall

본 발명은 강판전단벽으로서, 철근콘크리트 벽체에서 큰 전단력이 작용되는 연결부위의 벽체에 대한 구조적 일체성을 높이는 강판전단벽에 관한 것이다.The present invention relates to a steel sheet shear wall, which increases the structural integrity of the wall of the connecting portion where a large shear force is applied in the reinforced concrete wall.

도 1은 철근콘크리트 벽체로 구성된 건물 및 상기 건물에 작용되는 횡방향 외력에 의해 발생된 상하방향 전단응력이 나타낸 도면이고, 도 2는 도 1의 철근콘크리트 벽체 내의 철근을 나타내며, 그 중에서도 창문 등과 같은 개구부들 사이 부분에 수직방향보다 횡방향에 더 많은 수가 구성되는 철근을 나타낸 도면이다.1 is a view showing a vertical shear stress generated by a building composed of a reinforced concrete wall and a lateral external force acting on the building, and FIG. 2 shows a reinforcing bar in the reinforced concrete wall of FIG. It is a figure which shows the reinforcing bar which comprised more numbers in the transverse direction than the perpendicular direction to the part between opening parts.

도면을 참조하면, 연속된 개구부를 지닌 하나의 큰 벽체가 횡하중을 받게 되는 경우, 양쪽의 벽체는 각각 압축 및 인장력에 저항하게 되고 두 벽체를 연결해주는 중간 부분의 벽체에는 큰 전단력이 작용하게 된다.Referring to the drawings, when one large wall with continuous openings is subjected to lateral loads, both walls resist compressive and tensile forces, respectively, and a large shear force is applied to the wall in the middle portion connecting the two walls.

이와 같이 큰 전단력이 작용되는 연결부위의 벽체를 병렬 전단벽이라 하고 이러한 벽체의 취성파괴를 예방하기 위해, 도 2에 도시된 바와 같이, 조밀한 철근 배근을 통해 벽체를 구성한다.As described above, the wall of the connection portion where the large shear force is applied is called a parallel shear wall, and to prevent brittle fracture of the wall, as shown in FIG.

조밀한 철근 배근에 따른 작업능률 저하와 시공 과정에 대한 신뢰성, 기존 벽체와의 연결 문제로 인해 이와 같은 점을 개선하기 위한 여러 가지 철근 배근이 지금까지 시도되어 왔다.Due to poor work efficiency due to dense reinforcement, reliability of construction process, and connection with existing walls, various reinforcement have been attempted to improve this point.

예를 들어 대각방향의 철근 배근을 증가시키는 방법 등이 있다. 이러한 벽체의 강성 및 강도를 효과적으로 증진시키기 위해서 기존의 철근-콘크리트벽체 대신 강판전단벽을 사용할 수 있으나, 면외방향으로 발생하는 좌굴 등의 문제로 효과적인 해결책이라고 할 수 없다.For example, there is a method of increasing the reinforcement in the diagonal direction. In order to effectively increase the rigidity and strength of the wall, steel sheet shear walls may be used instead of the existing reinforcement-concrete walls, but it is not an effective solution due to problems such as buckling occurring in the outward direction.

따라서 강판전단벽과 철근-콘크리트벽체를 합성 벽체로 사용하는 방안도 고려되고 있으나 두 벽체 사이의 구조적 일체성을 확보하기 어렵고 시공이 어려운 단점이 있다.Therefore, the method of using the steel sheet shear wall and the reinforced-concrete wall as a composite wall is also considered, but it is difficult to secure structural integrity between the two walls and construction is difficult.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 철근콘크리트 벽체에서 큰 전단력이 작용되는 연결부위의 벽체에 대한 구조적 일체성을 높이는 강판전단벽을 제공하는 데에 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a steel sheet shear wall to increase the structural integrity of the wall of the connection portion where a large shear force is applied in the reinforced concrete wall.
