External reinforcing ring type square steel post special-shaped node with different beam heights

Abstract

The invention provides an external reinforcing ring type square steel post special-shaped node with different beam heights. The external reinforcing ring type square steel post special-shaped node comprises a square steel post, external reinforcing annular boards, a connection web plate, an H-shaped steel beam and a bolt, has no need of cutting a post wall, and keeps the continuousness of the post, so that the penetration of the post can be realized. The three external reinforcing annular boards are welded on the square steel post through fillet seams according to the size of the H-shaped steel beam; the connection web plate is welded on the post wall through the fillet seams according to a specific size of the H-shaped steel beam; the connection positions of the connection web plate and the external reinforcing annular boards are fixedly welded through the fillet seams; and on the top external reinforcing annular board and the bottom external reinforcing annular boards, the connection web plate is welded with a web plate of the H-shaped steel beam by using a high-strength bolt at a specific position of the post, and the connection positions of the external reinforcing annular boards and a flange of the H-shaped steel beam are fixedly connected by using the fillet seams. The external reinforcing ring type square steel post special-shaped node provided by the invention realizes rigid connection of the node of a beam post. Compared with the conventional beam post rigid connection node manner, the novel node of the beam post has better carrying capacity, so that safer storage is reserved for a building.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a special-shaped joint of an externally reinforced ring-type square steel column with different beam heights. Background technique [0002] Since my country's reform and opening up, housing construction has developed rapidly, and the growth of population and the acceleration of urbanization have caused the demand for housing to increase in our country. In order to meet the ever-increasing demand for housing, accelerate the process of housing construction, and promote the modernization of the housing industry, in 1999 the State Council forwarded the "Several Opinions on Promoting the Modernization of the Housing Industry and Improving the Quality of Housing" (Guobanfa [1999] 72 No.), to propose and introduce advanced residential building systems and complete sets of engineering technologies to improve the quality of residential buildings and drive the development of related i...
