THE SELF POSITIONING JOINT STRUCTURE BETWEEN PRECAST STEEL-CONCRETE COMPOSITE COLUMN AND PRECAST STEEL-CONCRETE COMPOSITE BEAM
The purpose of the present invention is to provide a self positioning connection structure of a precast SRC pillar and a precast SRC beam, which is conducted by a moment connection structure, not by a conventional pin connection structure, enables self positioning between plates during construction of a joint connection, can flexibly be applied to various structures and forms, and can be constructed by an unskilled worker in a short time because this structure is constructed by a dry process using prefabricated members. In order to achieve this purpose, the self positioning connection structure of a precast SRC pillar and a precast SRC beam, comprises: a precast SRC beam (100) including a steel beam (110) and a concrete beam (150) covering the steel beam (110); a precast SRC pillar (200) including a steel pillar (210) and pillar concrete (250) covering the steel pillar (210); a beam plate (130) coupled to an end part of the steel beam (110), wherein a setting bolt insertion hole (132) is formed on a lower part; an anchoring steel bar (270) which is laid U-shaped, is installed through the steel pillar (210), and is embedded in the concrete pillar (250); a pillar plate (230) whose part is embedded in an external surface of the concrete pillar (250) to be installed thereon, and which is coupled to an end part of the anchoring steel bar (270) on which a male screw thread is formed by an embedding nut (260) on which a female screw thread is formed; and a setting bold (SB) installed on a lower part of the pillar plate (230) to be externally exposed. In this regard, when the beam plate (130) descends in a state of contacting with the pillar plate (230), the setting bolt (SB) is inserted into the setting bolt insertion hole (132) to enable self positioning. In addition, the present invention provides the self positioning connection structure of the precast SRC pillar and the precast SRC beam, which is characterized in that the anchoring steel bar (270) is omitted, and the embedding nut (260) is welded to a front flange (212) of the steel pillar (210).
