The horizontal plane of top angle steel and the top flange of girder steel are by high strength exploitation, and the vertical plane of top angle steel and steel column are by the high strength exploitation through extended end plate; The bottom horizontal plane of angle steel is connected by friction type high strength bolt with the bottom flange of girder steel, and the vertical plane of bottom angle steel is connected by the friction type high strength bolt through extended end plate with steel column side; First vertical plane of left web-angle is clipped the web of girder steel with the first vertical plane of right web-angle and is connected by friction type high strength bolt, second vertical plane, the extended end plate of left web-angle are connected by friction type high strength bolt with steel column side, and top flange, the bottom flange of the second vertical plane of right web-angle, extended end plate and steel column are connected by friction type high strength bolt.
Preferably, described high-strength bolt is friction type high strength bolt.
Preferably, described high-strength bolt is monolateral bolt.
The present invention has following advantage relative to prior art:
1, steel column, fit tightly together between girder steel and two equal leg angles, hole is relative, and adopt high strength exploitation, do not adopt any welding procedure, steel do not become fragile, and initial stiffness is large, yield strength is high, hysteresis loop is full, anti-seismic performance is good.
2, steel core concrete column, top-seat-angle steel, full bolt connection node combination creatively combine by the present invention, it is high that friction type high strength bolt connects bearing capacity, power performance is good, adopt top-seat-angle steel-full bolt connection node, improve the ductility of steel-structure beam-column node, enhance node energy dissipation ability, further increase the anti-seismic performance of structural entity.
