Steel structure beam column mortise-and-tenon-joint-type fast installing joint and installing method thereof

Abstract

The invention discloses a beam-column mortise-and-mortise quick-installation joint of a steel structure and an installation method thereof. The joint comprises a steel pipe column and a steel beam. The steel pipe column is provided with a reinforcing plate, the reinforcing plate is provided with an embedded groove, and the steel beam is provided with an end plate. , the end plate is provided with an embedded tenon, which matches the embedded groove, and a self-locking bolt is provided between the second bolt hole and the first bolt hole. The self-locking bolt includes an outer bolt and an inner core bolt, and the outer bolt is provided with a The hexagonal nut is provided with an inner expansion blade at the end of the outer bolt. The installation method includes: (a) fabrication and installation of reinforcement boards; (b) fabrication and installation of end plates; (c) fabrication of outer bolts and inner core bolts; (d) self-locking connection of steel pipe columns and steel beams; (e) Manufacture of self-locking bolts; (f) tight connection of steel pipe columns and steel beams; (g) installation inspection. The present invention has the characteristics of quick positioning of node construction and high installation accuracy, clear force transmission of node connection structure, quick construction, and solves the problem that bolts in the node area are not easy to construct.

Description

technical field [0001] The invention belongs to the technical field of assembled steel structures in construction engineering, and in particular relates to a beam-column mortise-and-mortise quick-installation joint of a steel structure and an installation method thereof. Background technique [0002] With the modernization of cities and towns and the rapid development of the national economy, the use of building functions has become increasingly complex. For multi-storey, high-rise, and super high-rise buildings, traditional concrete structures or pure steel structures have been difficult to meet the functional requirements. Concrete-filled steel tube columns are increasingly used in building structures due to their excellent performance. Research on a more reasonable connection form between concrete-filled steel tube columns and steel beams is a focus of current prefabricated steel structure technology research. [0003] At present, the joints between concrete filled steel ...
