Precast Composition I-Beam with Concrete Panel and Corrugated Steel Web Girder

摘要

The present invention is a cross section of the beam by synthesizing the concrete panel to the top and bottom of the steel material consisting of a corrugated steel girder to increase the rigidity, this segmentation unit length in the mixture to improve the workability precast concrete composite children - relates to a beam ; Technical configuration of the present invention to achieve this, the top of the steel girder and the steel girder and is made of the upper and lower concrete panel to be synthesized at the bottom, a plurality of through-holes formed in the upper and lower portions of the steel girder is disposed the bond reinforcement in a direction perpendicular to the longitudinal direction of the steel girder is inserted into the upper reinforcement is a combination and the lower portion is adapted to be embedded in the concrete panel; The web of the steel girder is composed of a corrugated steel plate having a curved wave shape in the longitudinal direction in order to improve its buckling strength; The lower concrete panel is disposed a tension on each side around the ginjangjae the corrugated steel plate is a post-tensioning system is configured to introduce the prestressing force; The steel girder and its combined upper and lower composite concrete panels consisting of child-beam is then divided into a plurality of unit length for one-span precast segmental approach to the synthesis kids produced in the construction site - each segment of the beam connection The connection between the adjacent corrugated plates assembled in part.
