Closed section column connecting structure and method

Abstract

The invention relates to a closed section column connecting structure and method. The connecting structure comprises a first column body, a second column body and a core tube. A first flange plate isarranged on at least one end face of the first column body, and a second flange plate is arranged on at least one end face of the second column body. The first flange plate and the second flange platecan be fixedly connected through bolts. One or more plug welding holes are formed in the column wall, close to the first flange plate, of the first column body and the column wall, close to the second flange plate, of the second column body correspondingly, and the core tube can be arranged in the first column body and the second column body in a penetrating manner and can be connected with the first column body and the second column body through a plug welding process via the plug welding holes. Industrial production is facilitated through the flange plates and the core tube, the core tube and the column walls are connected through plug welding, the performance of the connecting structure is guaranteed, efficient assembly is achieved, welding is reduced, and the construction progress iseffectively accelerated; and the requirements of the machining precision of the core tube and the column walls are lowered through the plug welding holes.

Description

technical field [0001] The present application relates to the field of fabricated steel structures, in particular to a closed-section column connection structure and method. Background technique [0002] In the current "Code for Seismic Design of Buildings" (GB50010-2010, 2016 edition) and "Technical Regulations for Steel Structures of High-rise Civil Buildings" (JGJ99-2015), there are mainly two forms of steel structure connection: weld and bolt connection. Columns, steel pipe columns and other closed-section columns are widely used, but the commonly used connection between box-section columns and columns is generally in the form of groove full penetration welding. Compared with bolt connection, field weld connection has the following disadvantages: (1) low efficiency of welding construction; (2) large demand for welder labor; (3) cumbersome inspection process for welding quality after welding is completed; (4) welding method It is greatly affected by the technical profici...

Problems solved by technology

Compared with bolt connection, on-site weld connection has the following disadvantages: (1) The efficiency of welding construction is low; (2) The demand for welder labor is large; (3) The inspection process of welding quality after welding is cumbersome; (4) The welding method It is greatly affected by the technical proficiency of welders. Inexperienced welders may seriously affect the welding quality, and even cause fires in severe cases.
