The present invention relates to a column-beam connection structure, and more particularly, to a column-beam connection structure for connecting a beam to a column. The present invention, the upper and lower rectangular pillars 110 and the lower rectangular pillars 120, and the upper rectangular pillars 110 and the lower rectangular pillars 120 at least one of the four sides to the coupling surface of the H-beam beam In the column-beam coupling structure in which 200 is coupled, the first beam support 320 is located on the H-beam 200 and coupled to the upper web 220 of the H-beam 200 and , The first beam support portion 320 and integrally formed with an upper coupling portion 300 including a pillar support portion 310 coupled to the coupling surface of the upper square pillar 110, and; A first beam support 520 that is positioned under the H-beam 200 and coupled to the lower web 230 of the H-beam 200, and the first beam support 520 are integrally formed. Disclosed is a column-beam coupling structure comprising a lower coupling part 500 including a first post support part 520 coupled to the coupling surface of the lower square pillar 120 .
