STEEL-CONCRETE COMPOSITE CROSSBEAM HAVING T-SHAPED BEAM AND CONSTRUCTION METHODS USING THE SAME

摘要

PURPOSE: A T-shaped steel concrete composite crossbeam and a bundling construction method thereof are provided to reduce the weight of a beam and reduce the amount of materials of a steel structure. CONSTITUTION: A T-shaped steel concrete composite crossbeam comprises a T-shaped steel structure(10), a stirrup reinforcing rod(11), a precast concrete(12), and an embedded reinforcing rod(18). The T-shaped steel structure comprises a web(13) and a bottom flange(14) extended along the longitudinal direction. The T-shaped steel structure is connected to the bottom of the web at a right angle. The stirrup reinforcing rod is installed in the T-shaped steel structure at regular intervals. The embedded reinforcing rod is buried within the precast concrete to the longitudinal direction.
