Beschreibung
Zusammenfassung:	The utility model relates to the technical field of seismic mitigation and isolation, in particular to an assembly type rotary friction damping device. The energy dissipation joint mainly comprises a plurality of energy dissipation joints, each energy dissipation joint mainly comprises a plurality of pressing plates, friction steel plates and friction materials, the friction steel plates and the pressing plates are arranged in a laminated mode to form a connecting rod mechanism, a certain initial included angle theta is formed between the pressing plates and the friction steel plates, and the friction materials capable of generating friction force are arranged between the friction steel plates and the pressing plates. Traditional horizontal friction energy consumption is converted into rotary friction energy consumption, and friction output is adjusted by adjusting an initial included angle, additionally arranging energy consumption nodes and adopting a combined mode of parallel arrangement. The damping devic
