Tube assembly joint

Abstract

The invention relates to a tube assembly joint, and belongs to the technical field of tube connection. The tube assembly joint mainly solves the problems that a truss is large in integral cross section so as to be inconvenient to transport in actual engineering, and the on-site assembly of the assembly truss occupies a large space, the assembly welding workload is high, on-site welding conditionsof rod pieces are poor, and welding quality can not be guaranteed. According to the technical scheme, the tube assembly joint comprises a device I and a device II which are respectively arranged at the two ends of a butt-joint steel tube interface; stiffening grooves are formed in the two ends of the butt-joint steel tube interface; the device I comprises a cross stiffening plate I and a left connecting flange plate, and a sheath tube is arranged on the periphery of the portion, extending out of a left butt-joint steel tube, of the cross stiffening plate I; the device II comprises a cross stiffening plate II and a right connecting flange plate; and the left connecting flange plate of the device I is connected with the right connecting flange plate of the device II through a high-strength bolt. The tube assembly joint has the advantages of being novel in structure, convenient to install and the like.

Description

technical field [0001] The invention belongs to the technical field of pipe connection, and in particular relates to a pipe assembly node. Background technique [0002] The long-span space structure is an important standard to measure the level of a country's architectural technology, and it is also a symbol of the development of a country's civilization. It has a beautiful space shape, and has the advantages of a single member, reasonable force, high rigidity, and light weight. All countries in the world attach great importance to the theoretical and technical research of its structure. In the past 10 years, with the development of my country's economy and the continuous progress of science and technology, steel structures of various shapes in the span space have been used in sports venues, exhibition centers, theaters, airports, aviation, etc. It is widely used in large public buildings such as station buildings and railway stations. [0003] However, in actual engineering...
