Composite Beam Stiffened with Prestressed Concrete Panel Having Embedded Lower Flange and Constructing Method thereof

摘要

In the present invention, the steel beam 10 and the pre-cast concrete panel (20) is a precast concrete panel composite beam made of a composite, the top surface of the precast concrete panel 20 lower flange 13 of the steel beam (10) a recess which is embedded in location (27) is formed; The steel beam 10, the recessed portion 27 has a secondary concrete 26 is poured above the steel beam in a state located in the recessed portion 27 of the lower flange 13 is the pre-cast concrete panels 20 of the 10 and the pre-cast concrete panels 20 are synthesized, and; There is provided with the pre-cast concrete panel (20), reinforced connecting reinforcement (29) for reinforcement, wherein the reinforcement connecting reinforcement (29) is the second concrete (26) have a part thereof is exposed to the concave portion 27 When the casting is provided with a precast concrete panel composite beam of the lower flange embedded and integrally connected structure, it characterized in that the exposed portion of the reinforcing connection reinforcement (29) has a structure that is embedded in the second concrete (26). ; Composite beam, tension, prestressing, assembly, steel beams, connection
