The invention discloses a connecting structure of a concrete-filled
steel tube column and a
reinforced concrete beam. The connecting structure comprises the concrete-filled
steel tube column made of a
steel tube and concrete and the
reinforced concrete beam made of a reinforcing
steel bar and concrete; a boom extending steel beam is welded on the outer side surface of the steel tube and consists of flanges and a web plate; pull and tie plates parallel to the flanges are symmetrically welded on the two sides of the web plate; bar penetration holes are formed in the pull and tie plates; the reinforcing
steel bar comprises longitudinal bars arranged on the upper side and the lower side,
lumbar bars arranged on the left side and the right side, a first
stirrup connected onto the longitudinal bars and the
lumbar bars in a bundling manner and a pull and tie bar with two ends respectively colluded on the crossed
lumbar bars and the first
stirrup; one end of the
reinforced concrete beam is inserted into the boom extending steel beam; the pull and tie bar is
cut into two sections by the web plate of the boom extending steel beam, and the
cut ends of the pull and tie bar are inserted into the bar penetration holes. Through the overlap joint of the reinforcing
steel bar and the boom extending steel beam, the anchorage and the force transmission of the reinforcing steel bar are realized. The connecting structure disclosed by the invention has the advantages of being strong in bending and shear
bearing capacity, small in
welding workload, simple in mounting process and convenient and quick to construct.
