Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings:

[0020] Such as Figure 1 to Figure 7 As shown, a fabricated hollow hub node includes a hollow hub 1. The hollow hub 1 is provided with threaded holes for fixing bolts 2, and a connecting plate 3 is connected to the bolt 2 located outside the hollow hub 1. The connecting plate 3 and the hollow The bolt 2 between the hubs 1 is provided with a non-grain nut 4 with a fastening screw 5, and the bolt 2 is provided with a sliding groove 6 for clamping the fastening screw 5, and the sliding groove 6 has a deep A groove and a shallow groove are formed, a welding groove 8 is provided on the connecting plate 3, and the connecting plate 3 is welded to the rod 7 through the welding groove 8 and fixed.

[0021] In this embodiment, the hollow hub 1 is made of thick-walled steel pipe or round steel by cutting, milling, drilling, tapping and other processes. The bolt 2 is made of high-strength bolts wi...

Abstract

The invention discloses an assembly type hollow hub joint. The assembly type hollow hub joint comprises a hollow hub, wherein threaded holes are formed in the hollow hub and are used for fixing bolts, the outer side of the hollow hub is connected with connecting plates with welding slots through the bolts, an unthreaded nut with a fastening nut is arranged on a part, located between the corresponding connecting plate and the hollow hub, of each bolt, sliding slots for clamping the fastening nuts are formed in the bolts, and the connecting plates are connected with rod pieces through the welding slots. According to the assembly type hollow hub joint, assembly type construction of a single-layer latticed shell can be implemented, field welding is eliminated, welding heat effect is reduced, construction precision is improved, time limit for a project is shortened, a false screw situation of the bolts can be effectively prevented, and rigidity and bearing force of the joint are ensured to facilitate popularization and application of a large-span space structure.

Description

technical field [0001] The invention relates to a large-span space structure with complex stress, and more specifically relates to a single-layer reticulated shell structure with assembled hollow hub nodes. Background technique [0002] The current "Technical Regulations for Spatial Grid Structures" (JGJ7-2010) stipulates that single-layer reticulated shells should adopt rigid joints, such as welded ball joints, and rods are mostly made of round steel pipes, rectangular steel pipes and H-shaped steel, etc., which are currently used in single-layer grid structures. The joints of reticulated shells include welded hollow ball joints, diaphragm welded joints, thick-walled steel pipe joints, intersecting joints and cast steel joints, etc., but these joint forms have shortcomings. Welded joints such as welded hollow ball joints, bulkhead welded joints and thick-walled steel pipe joints require on-site assembly and welding, which is cumbersome to construct and is not conducive to t...
