Assembly type space pipe truss connection node structure and application method thereof

The invention provides an assembly type space pipe truss connecting node structure and an application method thereof.The node structure comprises truss chord members, truss web members, threaded sleeves and anti-seismic connecting pieces, bolts are arranged at the ends of the truss web members, and each anti-seismic connecting piece comprises a first nut, an anti-seismic spring and a first damping cushion block; the two ends of the anti-seismic spring are fixed to the first nut and the first damping cushion block respectively, the first nut is in threaded connection to the bolt, the first damping cushion block sleeves the outer wall of the bolt, the anti-seismic spring is located on the peripheral side of the bolt, the threaded sleeve is fixed to the truss chord member, and the bolt is in threaded connection in the threaded sleeve. The large-span space pipe truss connecting node has excellent mechanical property and stability, can provide stronger anti-seismic protection for a large-span space pipe truss stru
