A light steel structure rectangular tube beam-column connection node

Abstract

The invention discloses a connection joint for a rectangular steel pipe beam column of a light steel structure. The connection joint comprises a square pipe column, two installation sleeves and two rectangular pipe girders; a rectangular pipe suspension back beam penetrates through the square pipe column; the two installation sleeves are symmetrically fixed to the two ends of the rectangular pipe suspension back beam; the two rectangular pipe girders are fixed to the two installation sleeves correspondingly; each installation sleeve is internally provided with a first fixing plate and a second fixing plate, a fixing column penetrates through the first fixing plate and the second fixing plate; the rectangular pipe suspension back beam is provided with a first matching groove matched with one ends of the fixing columns; the rectangular pipe girders are provided with second matching grooves matched with the other ends of the fixing columns; and each first fixing plate is provided with a first support matched with the rectangular pipe suspension back beam, and each second fixing plate is provided with a second support matched with the corresponding rectangular pipe girder. According to the connection joint, assembling and disassembling are convenient, the overall structural connection strength is high, the installation period of the light steel structure on site is shortened, the work amount of on-site welding of the light steel structure is decreased, the discharged quantity of harmful substances on site is decreased, and the labor intensity is relieved.

Description

Technical field [0001] The invention belongs to the technical field of steel structure manufacturing, and specifically relates to a light steel structure rectangular tube beam-column connection node. Background technique [0002] With the continuous development of my country’s economy, the concept of residential building industrialization has gradually become popular with the country and society, and has developed rapidly; compared with the previous cast-in-place construction, the amount of wet work on the prefabricated structure building has decreased and the construction speed Fast, low labor demand, reliable product quality, can effectively improve production efficiency, shorten construction period, reduce pollution and noise, and conform to the national policy of promoting the industrialization of residential buildings. [0003] The key problems in the engineering design of prefabricated structures include joint connection design. The integrity, rigidity and load-bearing capacit...
