DIAGRID NODE OF CONCRETE FILLED STEEL TUBE AND CONSTRUCTION METHOD THEREFOR

摘要

PURPOSE: A joint structure of concrete filled steel pipe bracings in a diagrid system and a construction method thereof are provided to secure the structural stability, assemblability, and constructability of a concrete filled steel pipe node. CONSTITUTION: A concrete filled steel pipe node structure of a diagrid system comprises a connector(10) and four concrete filled steel pipe bracings(20). The connector, which joins the four concrete filled steel pipe bracings at a point, comprises a vertical plate(11) and two horizontal plates(12) coupled to the middle of the height of the vertical plate at the right angle. The four concrete filled steel pipe bracings are respectively coupled to four sections that are created by the vertical and horizontal plates.
