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

摘要

The present invention advantageously structurally By gradually relax ginjangjae placed in pre-cast concrete panel Precast ginjangryeok to ensure that the introduction of the concrete panel can make the most of the structural advantages of the composite beam, By filling in the bottom flange of the steel beam to concrete-panel precast concrete panels and steel beams also improve the synthesis of a new structure that precast concrete relates to a composite beam and a panel construction method. ; In the present invention, a steel beam 10 and the pre-cast concrete panel as 20 precast concrete panel is made of synthetic composite beam, the upper surface of the precast concrete panels (20), the steel beam (10 ) of the lower flange 13 is embedded is positioned recess 27 is formed, and; The concave portion 27 has a secondary concrete 26 is poured from the steel beam state in the recess 27 of the steel beam 10 of the lower flange 13 is the pre-cast concrete panel (20) is 10 and the pre-cast concrete panel (20) is provided pre-cast concrete panel composite beam of the lower flange having a buried structure, characterized in that the structure to be synthesized.
