Abstract

The invention discloses a fabricated concrete frame beam and column dry type connection joint low in cost, simple in structure, convenient to construct and good in anti-seismic property. The fabricated concrete frame beam and column dry type connection joint comprises a prefabricated concrete column (1) and a prefabricated concrete beam (2) and further comprises a column side connection steel plate (4) and a beam end connection steel plate (5). The back face of the column side connection steel plate (4) is fixedly connected with the connection side of the prefabricated concrete column (1). Theback face of the beam end connection steel plate (5) is fixedly connected with the connection end of the prefabricated concrete beam (2). The front faces of the column side connection steel plate (4)and the beam end connection steel plate (5) are opposite, and the column side connection steel plate (4) and the beam end connection steel plate (5) are detachably and fixedly connected. Preferentially, anchoring ribs (3) are arranged on the back face of the column side connection steel plate (4). One end of each anchoring rib (3) is fixedly connected with the back face of the column side connection steel plate (4), and the rest of each anchoring rib is buried in the prefabricated concrete column (1).

Description

technical field [0001] The invention belongs to the technical field of concrete frame structures, in particular to an assembled concrete frame beam-column dry connection node with low manufacturing cost, strong energy consumption capacity, convenient construction and good seismic performance. Background technique [0002] In order to meet the seismic performance requirements of the prefabricated concrete frame structure, the reliability of the connection between prefabricated columns and prefabricated beams is generally resolved through relevant structural measures. [0003] The currently known precast concrete beam-column dry connection structure includes prefabricated beams and prefabricated columns with pre-embedded steel, and later prefabricated beams and prefabricated columns are connected by bolts or welding through the leaked prefabricated steel; or through self-prefabricated columns and prefabricated columns. A hole is left on the beam. When the prefabricated beam an...
