Abstract

The invention discloses a replaceable assembly type frame beam column energy-consumption connecting key. The energy-consumption connecting key comprises end plates, a web plate and flange plates; theend plates comprise first and second end plates vertically arranged in parallel; the first end plate is detachably fixed on a frame concrete beam; the second end plate is detachably fixed on a frame concrete column; the web plate is vertically arranged between the first and second end plates; the left and right ends of the web plate are in vertical fixed connection with the first and second end plates; the flange plates are arranged at the upper and lower ends of the web plate, and are horizontally arranged; and the left and right ends of the flange plates are in vertical fixed connection withthe first and second end plates. The web plate and the flange plates are arranged between the end plates to form the energy-consumption connecting key; the energy-consumption connecting key can provide enough bearing force, and meanwhile, achieves the effects of ductility, deformation and energy consumption to guarantee the safety of a main body structure to the greatest extent; and the end plates and the frame concrete beam and column are in detachable fixed connection to guarantee replacement and repair of the connecting key in time.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a replaceable assembled frame beam-column energy-dissipating connection key. Background technique [0002] In the prefabricated concrete frame structure, the intersection of prefabricated beam and column components is called the beam-column node, also known as the beam-column core area, which is an important stress-bearing part of the structure. The seismic performance of prefabricated buildings largely depends on the connection reliability of beam-column joints. The design concept of "weak components" requires sufficient bearing capacity in small earthquakes and excellent deformation performance in large earthquakes. The deformation of the connecting keys is used to dissipate the seismic input energy, thereby protecting the main structure. [0003] With the development of prefabricated buildings, dry connection technology is in line with the trend of industrial develo...
