Embodiment

[0045] This embodiment provides an assembled steel structure beam-column energy-dissipating connection key, including two connecting steel beams on the left and right, and the two connecting steel beams on the left and right are hinged and fixed by hinge bolts; wherein, the connecting steel beam near the column on the left side is shorter , the distance between the right connecting steel beam and the column is approximately equal. Cut the 200-400mm of the hinged ends of the left and right connecting steel beams respectively, cut off the upper and lower flanges of the left and right connecting steel beams, and cut the web into an arc-shaped structure; Hinge bolt holes are provided at the corresponding positions of the web ends of the two connecting steel beams to ensure that the left and right connecting steel beams are aligned up and down when the two connecting steel beams are connected by hinge bolts through the hinge bolt holes.

[0046] In this embodiment, energy-dissipati...

Abstract

The invention discloses a fabricated steel structure beam-column energy dissipation connector. The connector comprises a first connecting steel beam, a second connecting steel beam and two energy dissipation plates, wherein the first connecting steel beam and the second connecting steel beam are horizontally arranged between a steel column member and a steel beam member, one end of the first connecting steel beam is fixed to the steel column member, the other end of the first connecting steel beam is hinged to one end of the second connecting steel beam, the other end of the second connectingsteel beam is fixed to the steel beam member, hinge shafts of the first connecting steel beam and the second connecting steel beam are horizontally arranged, the two energy dissipation plates are symmetrically arranged on the upper side and the lower side of the first connecting steel beam and the second connecting steel beam, and the two ends of the energy dissipation plates are detachably fixedto the first connecting steel beam and the second connecting steel beam correspondingly. According to the connector, by means of the mutually hinged connecting steel beams, a relatively weak area is formed at the beam end of a steel frame beam-column joint area, the controllability of a beam end shaping hinge is achieved, the energy dissipation plates can effectively absorb earthquake capacity, damage to a beam-column joint of a steel structure is avoided, the overall anti-seismic property of the structure is improved, post-earthquake repair is facilitated, and the repair and reinforcement cost is obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of assembled steel structure connection nodes, in particular to an assembled steel structure beam-column energy-dissipating connection key. Background technique [0002] In the prefabricated steel frame structure, in addition to meeting the basic bearing capacity requirements, the structure should also meet the principles of "strong shear weak bending", "strong column weak beam" and "strong node weak member" in seismic design to achieve The anti-seismic fortification goal of "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes"; the beam-column joint area of ​​the fabricated steel frame structure is of great significance to the overall bearing capacity and seismic performance of the structure, and is the key point for the entire structure to bear the force. critical area. [0003] At present, there are many beam-column connection methods in the existi...
