Connecting joint of fabricated steel structure and prefabricated externally-hung wall panel with damping performance

Abstract

The invention discloses a connecting joint of a fabricated steel structure and a prefabricated externally-hung wall panel with damping performance. The connecting joint of the fabricated steel structure and the prefabricated externally-hung wall panel with the damping performance comprises a lower frame beam, an upper frame beam and an externally-hung wall panel, wherein the lower frame beam is connected with the externally-hung wall panel through a lower joint connecting piece, and the upper frame beam is connected with the externally-hung wall panel through an upper joint connecting piece; the lower joint connecting piece comprises an arc-shaped steel plate, a connecting steel plate and a rib plate; the connecting steel plate is connected with the lower frame beam in a fastening mode through bolts; the arc-shaped steel plate is connected with the externally-hung wall panel in the fastening mode through high-strength bolt; the high-strength bolt is sleeved with at least one belleville spring; the upper joint connecting piece comprises a first steel plate and a second steel plate connected with the first steel plate, and the first steel plate is connected with the upper frame beam; a steel cover plate is arranged at the position, connected with the first steel plate, of the upper frame beam; the second steel plate is connected with the externally-hung wall panel through the bolts; a rubber sheet is arranged between the first steel plate and the second steel plate.

Description

technical field [0001] The invention belongs to the field of steel structure buildings, and relates to a connection node between an assembled steel structure with shock-absorbing performance and a prefabricated external wall panel, and is especially suitable for areas with high earthquake occurrence frequency and high fortification intensity. Background technique [0002] my country's prefabricated buildings are in a stage of rapid development. The country has issued a series of policies to promote prefabricated buildings. The popularity of prefabricated buildings has become a trend, especially in the prefabricated steel structure residential system. In the prefabricated steel structure building, the enclosure wall panel is one of the important components. As a kind of enclosure wall panel, the external wall panel is developing rapidly. The connection mode between the main body of the steel structure and the external wall panels has an important influence on the seismic perf...

Problems solved by technology

[0003] In view of the fact that the rigid joints cause serious damage to the wall panels and the flexible connection cannot effectively utilize the strength and stiffness of the wall panels, the present invention proposes a semi-rigid connection form. This node structure can realize that when the earthquake load is small, the wall panels and There is no slippage between the main structures, and they are stressed together, so that the lateral resistance capacity of the wall panels can be effectively exerted; when the earthquake load is large, the high-strength bolts slide in the oblong holes of the gusset plate, and are consumed by friction and plastic deformation of the joints. Seismic energy, reducing damage to wall panels under strong earthquakes
