Abstract

The invention discloses a lightweight steel structure rectangular-tube beam column connecting joint. The connecting joint comprises a connecting sleeve, a first rectangular-tube beam column and a second rectangular-tube beam column, wherein a limiting protrusion is inserted into a limiting groove, first screw holes are formed in the connecting sleeve and the first rectangular-tube beam column, second screw holes are formed in the second rectangular-tube beam column and the connecting sleeve, a first bolt is screwed into the first screw holes, the tail end of the first bolt is screwed out of the first screw holes and provided with a third screw hole, a second bolt is screwed into the third screw hole, the second bolt is screwed into the second screw holes, the tail end of the second bolt isscrewed out of the second screw holes, a fourth screw hole is formed in the tail end of the second bolt, a fifth screw hole is formed in the head of the first bolt, a third bolt is screwed into the fifth screw hole, the tail end of the third bolt is screwed into the fifth screw hole, and a triangular structure is formed by the the third bolt, the first bolt and the second bolt; and the lightweight steel structure rectangular-tube beam column connecting joint has excellent anti-loosening performance.

Description

technical field [0001] The invention relates to a light steel structural rectangular tube beam-column connecting node. Background technique [0002] With the continuous development of my country's economy, the concept of industrialization of residential buildings has gradually been favored by the country and society, and has developed rapidly; Fast, less labor demand, reliable product quality, can effectively improve production efficiency, shorten the construction period, reduce pollution and noise, in line with the national policy of promoting the industrialization of residential buildings. [0003] The key problems in the engineering design of prefabricated structures include node connection design. The integrity, stiffness and bearing capacity of prefabricated structure connection nodes have always been important factors restricting prefabricated structures; The connection method of bolts, but the anti-loosening effect of the structure connected by bolts is average at pre...
