A special-shaped column-beam-column joint structure

Abstract

The invention discloses a special-shaped column-beam-column joint structure, which comprises a square column (1) with a rectangular tubular structure in section and two beams (2), and the two beams (2) are connected and fixed by a sleeve (3) Integrate, the sleeve (3) can be socketed and matched with the square column (1) with an axial gap, and the two sides of the square column (1) are respectively provided with axillary beams (4) located below the cross beam (2), The ends of the added haunch beams (4) can be attached to the outer side of the square column (1) and slide; the two added haunch beams (4) are connected and fixed into one body through two parallel guide plates (41). The two ends of the guide plate (41) are respectively welded and fixed with positioning baffles (42) that can slide against the inner wall of the square column (1). The present invention has simple docking and installation methods, utilizes the gravity of the crossbeam to improve the bonding strength among beams, columns and haunched beams, and at the same time, the connection strength is stable and reliable, which is beneficial to its popularization in the application of prefabricated buildings.

Description

technical field [0001] The invention relates to the technical field related to prefabricated buildings, in particular to a special-shaped column-beam-column joint structure. Background technique [0002] In prefabricated buildings, the connection structure between steel beams and columns is the key to the strength of the entire building. At present, the common connection methods between steel beams and steel columns are mostly fixed by several bolt connections, and the entire butt installation process is very troublesome. Contents of the invention [0003] The object of the present invention is to provide a special-shaped column-beam-column joint structure, which can effectively solve the problems existing in the background technology. [0004] In order to solve the existing problems in the background technology, it includes a square column 1 with a rectangular tubular structure and two crossbeams 2, and the two beams 2 are connected and fixed together by a sleeve 3, which...
