JOINT STRUCTURE BETWEEN FLOOR SLAB AND STEEL GIRDER IN PRECAST CONCRETE FLOOR SLAB COMPOSITE GIRDER BRIDGE

摘要

PURPOSE:To improve constructing performance while having structural reliability and economize construction cost. CONSTITUTION:A stud dowel 22 is previously embedded in a precast concrete floor slab 21 in a shop fabrication stage, and the lower end of the stud dowel 22 is jointed to the horizontal piece 23a of steel 23 of T-shape cross section disposed being exposed from the lower edge of the floor slab 21. The vertical piece 23b hanging from the horizontal piece 23a is jointed to a vertical piece 25 erected from the upper flange of a steel girder 24 through a splice plate 26 and a high tension bolt 27.
