The invention discloses a T-shaped connecting piece and H-shaped steel beam combined frame structure joint construction method. The T-shaped connecting piece and H-shaped steel beam combined frame structure joint construction method has the following technical effects that compared with a mode of directly welding an H-shaped steel beam and a steel stand column, good ductility and toughness and buffering capacity during impact bearing are achieved while the strength is guaranteed, so that high anti-seismic performance is achieved. Each beam column joint is provided with an upper T-shaped connecting piece and a lower T-shaped connecting piece which are used for being connected with an H-shaped steel beam, so that the bearing strength of the joint is guaranteed while the ductility is improved. The T-shaped connecting pieces have connecting and buffering effects between beam columns, the bolt connection has the effects of energy absorption and extension when impact type external force is borne, even if threads are abraded after being impacted and cannot be continuously and safely used, the probability of overall collapse is lower than that of a direct welding mode, therefore, compared with a welding mode, the safety is high, and life and property safety of people can be protected.
Description
Technical field [0001] The present invention relates to the field of construction engineering, in particular, involving a T-type connector and an H-type steel beam combined frame structure node construction method. Background technique [0002] The node of the rigid beam and the rigid column connection in the steel structure engineering is the conversion hub between the components. The effects of strength, stiffness and overall stability of the structure are generally believed that the carrying capacity and stiffness of the rigid node are generally considered. Large, is the ideal seismic node form. The steel structural beam column nodes generally weld or penetrate the rigid linkage of the steel beam and the steel column. [0003] However, as the research and analysis of high-rise buildings in earthquake disasters in recent years have found that the beam columns have different degrees of brittle damage, while the nodes of the semi-rigid connection exhibit good ductility and energy...
