Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy connection nodes, in particular to an end single-side bolt assembled aluminum alloy structural node. Background Art

[0002] With the increasing application of aluminum alloy lattice shell structures in public and industrial buildings, aluminum alloy single-layer lattice shell structures are becoming a common main structure system. Their shapes are no longer limited to cylindrical lattice shells and spherical lattice shells, but are mostly complex free-form lattice shells.

[0003] The existing end single-side bolt assembled aluminum alloy structural nodes still have the following defects when in use: traditional aluminum alloy single-layer lattice shells mostly use plate nodes, the upper flange of the rod is connected to the upper node plate by stainless steel bolts; the lower flange of the rod is connected to the lower node plate by stainless steel bolts; the web is not connected. In the free-form surface lattice shell, the aluminum alloy node plates of the commonly used nodes are large in size, the upper and lower node plates are only connected to the upper and lower flanges of the rod, the web is not penetrated, and the closed member has better torsional resistance and stability. The installers cannot access the inside of the closed section, and the operating space is limited. Utility Model Content
