High-strength space steel structure joint and installation method thereof

Abstract

The invention provides a high-strength space steel structure joint and an installation method thereof, and belongs to the field of space steel structures. According to the high-strength space steel structure joint, the problem that the strength of existing space steel structure joint is low is solved. The high-strength space steel structure joint comprises a connecting pipe, a support pipe, an external support cylinder, an inner support cylinder, an upper sleeving plate, a lower sleeving plate, a connecting cylinder, an upper sealing plate and a lower sealing plate. The connecting cylinder includes connecting plates and fixed plates. The external arc surfaces of the fixed plates are fixed to the inner wall of the inner support cylinder. Outer sleeving holes are formed in the external support cylinder in the circumferential direction. Inner sleeving holes are distributed on the inner support cylinder in the circumferential direction. Connecting holes are formed in the connecting plates.The support pipe penetrates through the outer sleeving holes and the inner sleeving holes. The end of the support pipe is connected to the outer side surfaces of the connecting plates in a welding mode. The connecting pipe penetrates through the connecting holes and is connected with screw caps in a threaded mode. The upper sealing plate and the lower sealing plate are fixed on the two ends of the connecting cylinder. The connecting cylinder, the upper sealing plate and the lower sealing plate are encircled to form a pouring area. Concrete mortar is poured in the pouring area. The joint is suitable for on-site assembly, and the stress is clearer.

Description

technical field [0001] The invention belongs to the technical field of space steel structures, and relates to a high-strength space steel structure node and an installation method thereof. Background technique [0002] Spatial steel structure refers to a steel structure system with a large space span. Several nodes are connected by several rods. Due to the large number of rods required, usually tens of thousands are required, the structure of the nodes and the connection form with the rods will affect the entire space. The strength of the steel structure will be affected, and the construction and installation method will also directly affect the overall quality and construction efficiency. [0003] The existing space steel structure generally directly connects the end of the bar and the node through the fastener, and the strength and construction efficiency are low, so it is necessary to improve it. Contents of the invention [0004] The purpose of the present invention i...
