A Dry bonding system for A-type pillars and girders that do not require additional concrete pouring and dry bonding method using the same

The present invention relates to a dry bonding system for A-type pillars and girders and a dry bonding method using the same, wherein, when a concrete structure is constructed by using a precast concrete module, additional concrete pouring for connecting an A-type pillar to a girder is not required. Furthermore, because reinforcing bars are densely arranged, mutual interruption may be reduced, thereby improving constructability and reducing a construction period. To this end, the dry bonding system for A-type pillars and girders according to the present invention is characterized by comprising: an A-type pillar; first girder and a second girder which are respectively and temporarily supported at one side and the other side with respect to the upper end corner portion of the A-type pillar; a second girder which is located in a shape in which the front end portion faces from the other side with respect to the upper end corner unit of the A-type pillar, wherein a second reinforcing bar, arranged in a longitudinal direction, is exposed at the front end portion, and a second arrangement groove is formed to enable mortar placing; a middle connecting reinforcing bar which penetrates the reinforcing bar supporting hole of the A-type pillar, and of which one end portion is located close to the front end portion of the first reinforcing bar exposed from the first arrangement groove, and the other end portion is located to be close to the front end portion of the second reinforcing bar exposed from the second arrangement groove; and a plurality of clamps which are individually provided in the first arrangement groove and the second arrangement groove, restrict one end portion of the middle connecting reinforcing bar and the front end portion of the first reinforcing bar in the first arrangement groove as a single bundle, and restrict the other end portion of the middle connecting reinforcing bar and the front end portion of the second reinforcing bar in the second arrangement groove as a single bundle. 본 발명은 A형 기둥과 거더의 건식 접합시스템 및 이를 이용한 건식 접합방법에 관한 것으로, 프리캐스트 콘크리트 모듈을 이용한 콘크리트 구조물 축조 시 A형 기둥과 거더의 연결을 위한 덧침 콘크리트 타설이 필요하지 않으며 철근들의 조밀한 배근으로 인한 상호 간섭을 줄일 수 있어서 시공성을 향상시키면서 공사기간을 단축할 수 있도록 한 것이다. 이러한 본 발명에 의한 A형 기둥과 거더의 건식 접합시스템의 경우, A형 기둥; A형 기둥의 상단 모서리부에 대해 일측과 타측에서 각각 임시 지지되는 제1거더 및 제2거더; A형 기둥의 상단 모서리부에 대해 타측에서 선단부가 대면하는 형태로 위치하며, 선단부에는 종방향으로 배근된 제2철근이 노출되어 있고 모르타르 타설이 가능하도록 한 제2배근홈이 형성된 제2거더; A형 기둥의 철근 지지공을 관통한 상태에서 일단부는 제1배근홈에서 노출된 제1철근의 선단부 인근에 위치하고, 타단부는 제2배근홈에서 노출
