2-WAY SLAB DECK PLATE ARRANGING A WIDTHWISE LOWER BAR ON A LOWER BAR HORIZONTALLY, AND CONSTRUCTION METHOD FOR THE DECK PLATE

摘要

PURPOSE: The construction method for a 2-way slab deck plate is provided to improve constructability and mechanical efficiency by placing a widthwise steel bar of single steel on a lower bar simply. CONSTITUTION: The 2-way slab deck plate(10) contains: a truss(50) composed of an upper bar(20), a lower bar(30) and a lattice(40) supporting the lower bar(30) and the upper bar(20); a base(60) provided with laps(60a) formed on both longitudinal ends of the base(60) and ribs(60b) formed to weld to the foot of the lattice(40); and a widthwise lower bar(70) of single steel placed on the lower part of the lower bar(30) of the deck plate(10). The construction method for the deck plate comprises the steps of: preparing a 2-way slab deck plate(10) composed of a truss(50) and a base(60); preparing a widthwise lower bar(70) of single steel; advancing the front end of the widthwise lower bar(70) on the base(60) along the laps(60a); and after inserting the widthwise lower bar on the base, placing the widthwise lower bar(70) on the lower part of the lower bar(30).
