The closed cross-section component in the steel structure is popular with a large number of construction engineers and structural engineers due to excellent mechanical property and appearance feeling, and is often applied to large-scale exhibition halls, airport terminal buildings, residential buildings and large-scale shopping malls as a vertical stress component. The beam-column joint is one of the most critical structural parts in the buildings, and plays a key role in lifting weight in the structure.
The connection mode of beam column nodes is welding and bolt connection, wherein the connection of the closed section steel pipe column and the steel beam is mostly welded, but the welding can be influenced by weather environment and welding workers. In the process of infrastructure construction, the climatic environment is various, and the lack of professional welders is relatively common. It is therefore necessary to use bolting in such nodes.
The unilateral bolt is a special bolt type specially used for connecting a closed section component, and can be installed and fastened without entering a steel pipe. At present, the most economical unilateral bolt in the market belongs to a thread anchoring unilateral bolt, and is a more popular bolt type under study. The principle of the thread anchoring single-side bolt is that a hole is drilled and tapped on the wall of the steel pipe column, and then the steel beam and the steel pipe column are fastened through the traditional high-strength bolt. The technology anchors the high-strength bolt by means of the internal threads on the wall of the steel pipe column instead of the nut. However, the anchoring strength of the bolt is limited by the thick wall of the steel pipe column wall, and increasing the thickness of the column wall inevitably increases the amount of steel, which is very uneconomical.
