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

Abstract

The invention discloses a steel structure beam column mortise-and-tenon-joint-type fast installing joint and an installing method thereof. The joint comprises a steel pipe column and a steel beam. The steel pipe column is provided with a reinforced attaching plate. An embedding groove is formed in the reinforced attaching plate. The steel beam is provided with an end plate. An embedded tenon is formed in the end plate. The embedded tenon is matched with the embedding groove. A self-locking bolt is arranged between a second bolt hole and a first bolt hole. The self-locking bolt comprises an outer bolt and an inner core bolt. The exterior of the outer bolt is provided with a hex nut. The end part of the outer bolt is provided with an internally-extending blade piece. The installing method comprises the following steps of (a) reinforced attaching plate machining, manufacturing and installing, (b) end plate machining, manufacturing and installing, (c) outer bolt and inner core bolt manufacturing, (d), steel pipe column and steel beam self-locking connecting, (e), self-locking bolt manufacturing, (f), steel pipe column and steel beam fastening and connecting, and (g), installing and detecting. The steel structure beam column mortise-and-tenon-joint-type fast installing joint has the characteristics that joint construction is fast in place, and the installing precision is high, a joint connecting structure is accurate in force transferring and fast and convenient to construct, and the problem that the bolt at a joint area is not easily constructed is solved.

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 ...
