The reinforcing cage of described precast reinforced concrete beam is made up of upper and lower part steel bar stress and interval stirrup.
Frange plate and the web plate face of described structural steel connecting member are equipped with peg.
The one link of described precast reinforced concrete beam and structural steel connecting member, its layer of concrete fluted formula continued access end face.
A kind of precast reinforced concrete beam of the present invention and steel pipe column connected node, the steel bar stress welding of its structural steel connecting member in reinforced concrete beam prefabrication phase and beam in reinforcing cage, and steel hoop anchors in beam concrete in connector, add and structural steel connecting member is welded with peg, make structural steel connecting member become a part for precast beam; Structural steel connecting member is converted into the syndeton of steel work and steel work the syndeton of concrete structure and steel structure connection, the follow-up connecting end surface of layer of concrete groove type of the one link of precast reinforced concrete beam and structural steel connecting member, further increases integral node reliability; And structure of the present invention is simple and direct, reduce job site installation procedure, reduce difficulty of construction, therefore, the present invention is the permanent connected node that precast reinforced concrete beam and steel pipe column provide a kind of safe and reliable, easy construction.
