Problems solved by technology
If staggered seam splicing is used, welding stress is likely to occur at the weld; if high-strength bolts are used for connection, when the beam section is large, the number of bolts is large, the net section of the connection is greatly weakened, and the bolts are unevenly stressed, and the cost is also high. At the same time, the precision of hole making is difficult to guarantee
In addition, in order to meet the anti-seismic requirements of structures, the method of enlarging the cross-sectional size of members is often used, so the anti-seismic method of "making rigidity with rigidity" not only cannot effectively bear the energy input by earthquakes, but also cannot save costs

The invention discloses an assembled arc-shaped steel plate friction buckling energy-dissipating pin-connected box-shaped steel beam-column node, comprising a box-shaped steel beam, the two ends of which are connected to a first steel column and a second steel column, and further comprising Square steel pipe, pin and curved steel plate; the two ends of the curved steel plate are respectively fixed on the box-shaped steel beam and the steel column. When the square steel pipe is inserted into the box-shaped steel beam, the bolt can pin the box-shaped steel beam and the square steel pipe. The assembled arc-shaped steel plate friction buckling energy-dissipating pin-jointed box-shaped steel beam-column joints are pin-jointed. On the basis of meeting the bearing capacity, the pin-joint joints can rotate under the action of earthquakes to dissipate frictional energy, and the pin-joint joints do not need Welding and a large number of bolt connections make the beam-column joints have excellent mechanical performance; the arc-shaped steel plate can buckle and consume energy under the action of a large earthquake, and has strong capacity and is easy to replace.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and mainly relates to an assembled arc-shaped steel plate frictional buckling energy-dissipating pin-connected box-shaped steel beam-column node and an installation method, which can be specifically applied to an assembled steel structure building. Background technique [0002] Prefabricated steel structure buildings are mainly composed of steel materials and are one of the main building types in my country. The prefabricated steel structure building is mainly composed of steel beams, steel columns and other components, and the components are often connected by welding, bolts or rivets. Because of its light weight and convenient construction, it is widely used in residential buildings, public buildings and other construction fields. With the popularization and application of prefabricated steel structure buildings, large box steel beams are increasingly used in practical project...
