A connection structure between multi-leg lattice structure special-shaped column head and steel beam

Abstract

The invention discloses a connection structure between a multi-leg lattice type special-shaped column head and a steel beam, which comprises a steel column (1) and two beams (2), and the two beams (2) are connected by beam sleeves (3) fixed into one body, two slots (31) are provided on the lower bottom surface of the beam sleeve (3), and an axial positioning device is installed on the top of the steel column (1); the axial positioning device includes a vertical The steel plate (4) welded on the upper end surface of the steel column (1), the two sides of the upper top surface of the steel plate (4) are respectively vertically welded and fixed with a positioning plate (5) that can be inserted and matched with the slot (31) , the positioning plate (5) is fixed integrally with the beam sleeve (3) through bolts, and a radial positioning device is arranged between the two positioning plates (5). 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 connection structure between a multi-leg lattice structure special-shaped column head and a steel beam. 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 multi-legged lattice-type special-shaped column head and steel beam connection structure, which can effectively solve the problems existing in the background technology. [0004] In order to solve the problems existing in the background technology, it includes a steel column 1 and two beams 2, and the two beams 2 are ...
