combination structure of steel-frame structure with column and beam and its assembling method

In the coupling structure of the embodiment of columns and beams that make up the steel structure of the present invention, a pair of columns (column) portion which is provided so as to face each other with respect to the vertical in the plane; Beam (beam) portion which is provided is disposed in a direction perpendicular to the column section 10 and; Is provided at both ends of the beam sections 20 in order to fixedly coupled with the pair of column portions (10), is provided in a rectangular shape, the at least one engaging hole 31 is formed in one side, the coupling projection is stepped to form ( an upper flange portion 30 is provided with a 32) and; It is provided on the opposite ends of the beam 20, and the engaging shaft section 40 is provided with a cylindrical shape having a predetermined outer diameter; Wherein is provided at one side of the column unit 10, the and the column section 10 column junction 510 of rectangular shape is attached to the lower side which is provided by bonding in the direction perpendicular to the one end of the column joints 510 coupling section 520, and is provided by joining in the direction perpendicular to the other end of the column joint 510 is provided with a flange joint 531 in the shape corresponding to the shape of the coupling projection 32, the engaging shaft portion (40 It relates to a coupling structure of the columns and beams of steel structure which comprises a;) is coupled to coupling through groove 532 connecting brackets (50) consisting of an upper engagement portion 530 is formed. Then, the column section 10 is fixed by fixing position so as to be opposed each other, the column section 10 in a direction perpendicular to the while maintaining the predetermined spacing distance, the ground; In a direction perpendicular to the coupling groove 532 formed in the connecting brackets provided at a side of the column section 10 and the beam 20 is coupled positioning by mounting the coupling shaft provided at the both ends of the beam 20 .; And the upper flange coupling comprising: placing in contact with the coupling projection 32 of the upper flange and the flange joint (531); Assembly coupling fixedly coupled to the upper flange and the upper coupling parts of bolts and nuts and, fixed to the coupling hole 31 formed at the lower coupling portion and the beam sections 20 by a bolt and a nut; in the steel structure that comprises a It relates to an assembly method using the coupling structure of the columns and beams.
