Problems solved by technology

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 the development of building industrialization, and too many welds will affect the mechanical performance of the joints; The size of the main pipe and the branch pipe has certain requirements, which restricts its application to a certain extent; the cast steel joint has excellent performance but the cost is too high, which is not suitable for large-scale application

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described:

[0023] like Figure 1 to Figure 7 As shown, a high-strength bolt hollow hub node includes a hollow hub 1, the hollow hub 1 is provided with a connecting hole for connecting the high-strength bolt 2, and the outer side of the hollow hub 1 is connected with the non-threaded nut 4 and the high-strength bolt 2 in sequence. Connecting plate 3, the inner side of the hollow hub 1 is provided with a gasket 7 and a nut 8 for fixing the high-strength bolt 2, the gasket 7 is an annular gasket or an arc gasket, and when an annular gasket is used Milling should also be carried out at the corresponding position on the inner wall of the hollow hub 1; the fastening screw 5 is arranged on the non-threaded nut 4, and the chute 6 for clamping the fastening screw 5 is arranged on the high-strength bolt 2, and the chute 6 is formed by a deep Composed of grooves and shallow grooves, the connec...

Abstract

The invention discloses a high-strength bolt hollow hub node, comprising a hollow hub, the hollow hub is provided with connecting holes for connecting high-strength bolts, and the outer side of the hollow hub is sequentially connected with threadless nuts and connecting bolts through the high-strength bolts. The inner side of the hollow hub is provided with gaskets and nuts for fixing the high-strength bolts, the fastening screws are provided on the non-threaded nuts, and the fastening screws are provided on the high-strength bolts. The chute, the connecting plate is fixedly connected with a rod. The node of the invention can realize the assembled construction of a single-layer reticulated shell, eliminates on-site welding, reduces the heat influence of welding, improves construction accuracy, saves construction time, and can effectively prevent the phenomenon of "false tightening" of bolts, ensuring that the stiffness and bearing capacity of nodes are beneficial Popularization and application of long-span spatial structures.

Description

technical field [0001] The invention relates to a large-span space structure with complex stress, more specifically, a single-layer reticulated shell structure with high-strength bolt 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 the de...
