본 발명은 건축 구조물 안전 계단 설치구조에 관한 것으로, 더욱 상세하게는 조립식으로 시공되는 철골 계단의 하중을 분산 지지하여 계단의 구조적 안정성을 극대화시킬 수 있는 건축 구조물 안전 계단 설치구조에 관한 것이다.The present invention relates to a building safety stairs installation structure, and more particularly to a building structure safety stairs installation structure that can maximize the structural stability of the staircase by distributing and supporting the load of the steel staircase to be prefabricated.

일반적으로 이층 이상의 고층건물의 수직 동선을 연결하기 위해 엘리베이터와 함께 계단이 설치된다. 그런데, 이러한 계단은 좁은 계단실 공간 내에서 상하층의 슬래브 및 중간에 돌출된 계단참과 연결시켜야 하며, 특히 콘크리트로 시공하는 경우에는 거푸집 시공서부터 콘크리트 타설과 양생 그리고 거푸집 해체의 과정이 요구되므로 그 시공이 매우 까다롭다는 단점이 있었다. Generally, stairs are installed together with elevators to connect vertical copper lines of two or more high-rise buildings. However, these stairs should be connected to the upper and lower slabs and the protruding landings in the middle of the narrow staircase space. Especially, in case of concrete construction, the construction process is required from the formwork to concrete pouring, curing and dismantling of the formwork. It was very tricky.

따라서 근래에는 콘크리트나 철골조의 건물 등에서, 계단을 철제로 유니트화시켜서 제작하여 건물의 구체에 조립하여 연결하는 공법이 적용되고 있다.Therefore, in recent years, a method of manufacturing a unit made of steel in a concrete or steel-framed building, etc., assembling and connecting to a concrete sphere has been applied.

종래 철골을 이용한 계단의 시공구조는, 수직 통로를 형성하기 위한 수직 벽체와, 상기 수직 벽체에 상하 일정 간격마다 교대로 설치되는 슬래브와, 상기 슬래브 사이를 연결하는 계단을 포함한 구성으로 이루어진다.The construction of a staircase using a conventional steel frame has a configuration including a vertical wall for forming a vertical passage, a slab alternately installed on the vertical wall at regular intervals up and down, and a step connecting the slab.

여기서, 상기 슬래브에는 계단과의 연결을 위한 임베디드 앵글이 설치되어 있고, 이러한 임베디드 앵글에는 상기 상하 슬래브 사이를 연결하는 계단 끝단이 얹혀진 상태에서 볼트-너트 결합을 통해 견고히 고정됨으로써 건물의 상하층을 잇는 계단 통로를 형성하게 된다.Here, the slab is provided with an embedded angle for connecting to the stairs, and the embedded angle is connected to the upper and lower floors of the building by being firmly fixed by bolt-nut coupling in the state that the end of the stairs connecting the upper and lower slabs is mounted. A stairway is formed.

그런데, 상기와 같은 종래의 철골계단의 시공 구조는 상당한 하중의 슬래브 및 철골계단의 하중을 전적으로 수직 벽체가 지지하여야만 하는 구조로서 구조적으로 안정하지 못하여 지진 발생시 붕괴 위험이 높다.However, the construction structure of the conventional steel staircase as described above is a structure in which the vertical wall is to be fully supported by the slab and the steel staircase of considerable load, which is not structurally stable and has a high risk of collapse during an earthquake.

또한, 종래 다른 예로서, 계단이 벽체구조물에 매달기식으로 설치되고 있으나, 이 역시 구조적으로 안정하지 못하여 지진 발생시 붕괴 위험이 높다.In addition, as another example of the prior art, the stairs are installed on the wall structure by hanging, but this is also structurally unstable, high risk of collapse in the event of an earthquake.

본 발명은 상기한 종래 문제점을 해결하기 위한 것으로서, 계단의 하중을 효과적으로 분산하여 계단의 구조적 안정을 도모할 수 있는 건축 구조물 안전 계단 설치구조를 제공하려는데 그 목적이 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a safety structure installation structure for a construction structure that can effectively distribute the load of the stairs to achieve structural stability of the stairs.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 건축 구조물 안전 계단 설치구조는, 한 쌍의 계단지지대가 지면(또는 아래층)에 지지되도록 설치되며, 상기 한 쌍의 계단지지대 사이에 계단이 삽입되고, 상기 계단과 상기 계단지지대에 다수의 체결봉이 관통되면서 상기 계단지지대의 외측에서 각각 조임구가 체결되어 상기 계단이 설치되는 것을 특징으로 한다.Building structure safety stairs installation structure according to the present invention for achieving the above object, a pair of stair supports are installed to be supported on the ground (or downstairs), the staircase is inserted between the pair of stair supports, A plurality of fastening rods penetrate the staircase and the stair support, and fasteners are fastened from the outside of the stair support, respectively, so that the stair is installed.
