Fabricated outer ring plate beam column joint

Abstract

Provided is a fabricated outer ring plate beam column joint. The fabricated outer ring plate beam column joint comprises a structural column, and the front and rear portions of the structural column are respectively connected to outer ring plate channel steel connecting pieces through bolts; the outer ring plate channel steel connecting pieces comprise channel steel, channel steel bolt holes are formed in the channel steel, and the channel steel bolt holes are matched with structural column bolt holes in the structural column; outer ring plates arranged in parallel are welded to the channel steel, outer ring plate single row holes are formed in the bottom edges of the outer ring plates, and outer ring plate double-row holes are formed in the middles of the outer ring plates; the outer ringplate double-row holes in the middles of the outer ring plates are connected with I-shaped steel beam bolt holes in upper and lower flange plates of I-shaped steel beams through bolts; the channel steel is connected through stiffened angle steel, and vertical bolt holes in the stiffened angle steel are connected with the channel steel bolt holes in the channel steel through bolts; horizontal boltholes in the stiffened angle steel are connected with the outer ring plate single row holes in the bottom edges of the plates through bolts. The fabricated outer ring plate beam column joint can improve the rigidity and bearing capacity of the column and is convenient to construct.

Description

technical field [0001] The invention relates to a beam-column connection node in a building structure, in particular to an assembled outer ring plate beam-column node. Background technique [0002] Prefabricated structure is one of the important directions for the development of my country's building structure.

Problems solved by technology

[0004] The traditional beam and column construction adopts the method of on-site welding, and the upper and lower flanges and webs of the beam are welded to the column on site. This welding method forms a whole beam and column. Although it is a rigid connection, it leads to poor ductility. After welding, the residual stress is relatively large, brittle fracture is prone to occur, and the on-site welding workload is large, and the construction quality is difficult to control. This will greatly reduce construction efficiency and increase more labor and material costs. At the same time, it will also affect the environment. create pollution
