Q235B and Q355B steel pipes for construction are selected. The upper chord 1 uses double rods, and a planar truss is formed by welding the upper chord horizontal web members 2 and the upper chord inclined web members 3 between the double upper chords. The upper and lower chords are welded and connected through the vertical web members 4 and the inclined web members 5 to form a stable triangular space truss structure. Subsequently, precast concrete columns can be embedded with bolts, and the truss can be connected to the concrete column through the truss support nodes.
