Abstract

The invention discloses a connecting joint of a prefabricated reinforced concrete beam and a steel tube column, which belongs to the field of construction structures. The connecting joint consists of a prefabricated reinforced concrete beam, a prefabricated steel tube column and a structural steel connecting piece, wherein the structural steel connecting piece consists of an upper flange plate, a lower flange plate and a middle web; the structural steel connecting piece is arranged inside a reinforcement cage at one end of the prefabricated reinforced concrete beam; the upper flange plate and the lower flange plate are respectively correspondingly welded with upper load-bearing bars and lower load-bearing bars; concrete is cast along the structural steel connecting piece and the reinforcement cage so as to form integral connection of the prefabricated reinforced concrete beam and the structural steel connecting piece. In on-site construction, the structural steel connecting piece and the web which are integrally connected are connected with the connecting beam plate of the steel tube column, concrete is cast in situ between the end surfaces of the structural steel connecting piece and the prefabricated reinforced concrete beam, and complete connection of the prefabricated reinforced concrete beam and the steel tube column is achieved. The connecting joint is simple and convenient in structure, reduces the mounting process on the construction field, alleviates the construction difficulty, and is a safe and reliable permanent connecting joint which is simple and convenient to construct.

The reinforcing cage of described precast reinforced concrete beam is comprised of upper and lower part steel bar stress and interval stirrup.
The frange plate of described structural steel connecting member and web plate face are equipped with peg.
The one link of described precast reinforced concrete beam and structural steel connecting member, the fluted formula continued access of its layer of concrete end face.
A kind of precast reinforced concrete beam of the present invention and steel pipe column connected node, its structural steel connecting member is the welding of the steel bar stress in reinforcing cage in beam prefabricated stage of steel concrete and beam, and in connector, steel hoop anchors in beam concrete, add on structural steel connecting member and be welded with peg, make structural steel connecting member become a part for precast beam; Structural steel connecting member is converted into the syndeton of concrete structure and steel structure connection the syndeton of steel work and steel work, 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, has more increased 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 provides a kind of permanent connected node of safe and reliable, easy construction for precast reinforced concrete beam and steel pipe column.
