Self-reset concrete-filled steel tube column-steel beam node connecting device

Abstract

A self-reset concrete-filled steel tube column-steel beam node connecting device comprises a concrete-filled steel tube column, steel beams symmetrically connected to the two sides of the concrete-filled steel tube column through connecting steel plates, and energy dissipation components separately connected between an upper flange and a lower flange of each steel beam and the column side of the concrete-filled steel tube column. Two groups of anchoring plates spaced by a certain distance are symmetrically arranged on the two sides of a steel beam web plate, and upper prestressed steel bars and lower prestressed steel bars are respectively connected between the upper sides of the anchoring plates and the concrete-filled steel tube column as well as between the lower sides of the anchoringplates and the concrete-filled steel tube column. Beam-column joints are connected through steel plate bolts, local prestressed steel bars penetrate through a column body and are anchored at the beamends to realize self-reset, the upper and lower flanges of the steel beams are connected with the column side through L-shaped steel plates and high-strength bolts, and the L-shaped steel plates, friction plates and the flanges relatively slide in a friction mode to consume energy. The self-reset concrete-filled steel tube column-steel beam node connecting device has the advantages that connectionis convenient to implement, the structure is simple, and assembly can be realized due to adoption of bolt connection mostly. After an earthquake, the device can absorb shock, dissipate energy and reset automatically, and can be widely applied to the technical field of shock absorption and energy dissipation of building structures.

AI Technical Summary

Benefits of technology

This new method connects two parts called cathode ray tubes (CRT) or liquid crystal displays (LCD). These connections have advantages over existing techniques such as welding or riveting that provide better resistance against damage from external forces like impact. They also allow for easy maintenance without requiring expensive repairs during disaster situations.

Problems solved by technology

The technical problem addressed in this patented text relates to developing an improved design for buildings that resist seismicity caused during fires or other emergencies without losing their structural integrity due to damage from external forces such as explosions or firearms.
