Abstract

The invention relates to a fabricated beam-column joint with a recoverable function and a beam-falling-prevention device. The fabricated beam-column joint comprises a prefabricated concrete column, a built-in anti-compression damper and a beam-falling-prevention component, wherein the built-in anti-compression damper and the beam-falling-prevention component are fixed in the prefabricated concrete column, wherein lower column reserved longitudinal bars in a prefabricated concrete lower column are connected with upper column reserved longitudinal bars in a prestressed concrete upper column through steel bar sleeves; and joint concrete is poured after longitudinal bars on the upper portion of the beam penetrate through beam embedded stirrups. The defects that an existing assembly type beam-column joint is complex in site construction procedure, and the anti-seismic effect of an assembly type joint is poor are overcome; The fabricated beam-column joint can be directly used for beam-column joints, operation and installation are fast, the damper is easy to replace when damaged, and the maintenance cost is low.

Description

technical field

[0001] The invention relates to the technical field of assembled building structures, in particular to an assembled beam-column node with a recoverable function and an anti-drop beam device. Background technique

[0002] At present, my country's building construction mainly adopts traditional construction methods based on on-site construction. This method has a low degree of industrialization, a large demand for labor, large resource consumption, and serious environmental pollution. It cannot meet the requirements of energy saving, environmental protection, and sustainable development. In recent years, in order to meet the needs of "green buildings", "construction industrialization" and "housing industrialization", my country has begun to advocate the promotion of "industrialization mode" in construction, and has introduced relevant policies, which clearly put forward the requirements for prefabricated structures. development goals.
