Abstract

The connecting rod member for bolt ball node steel lattice consists of lattice connecting pipe, bolt ball node connecting joint and bolt ball. The lattice connecting pipe and the bolt ball node connecting joint are connected fixedly, and the bolt ball node connecting joint and the bolt ball are connected. The lattice connecting pipe is constituted with one composite steel-plastic structure pipe, which has end connected via thread structure to plate sealing conic head. The present invention has relatively small weight, and the lattice connecting pipe of composite steel-plastic structure is connected to the bolt ball node connecting joint in tooth mode without need welding, resulting in flexible, safe and convenient construction.

Description

Technical field: [0001] The invention relates to the field of construction, in particular to a steel structure, in particular to a node connecting member in a steel grid, in particular to a connecting rod for a bolt ball node steel grid. Background technique: [0002] In the prior art, grid steel structures are widely used in construction, decoration, advertisement and scaffolding structures due to their light weight, high rigidity, good shock resistance, and convenience for mass production. The connecting rods used for the bolt ball joint steel grid are the main structure in the current grid steel structure. At present, angle steel, channel steel, I-beam, and steel pipe are used to make various special cross-section steels. The connection method of the components is welded. Mainly. The grid steel structure is heavy, and the construction and installation are not convenient enough. In places where open flames are not allowed, such as gas stations, welding construction cannot...
