HOLLOW FLOOR SLAB UNIT FOR PREFABRICATED BRIDGE, HOLLOW FLOOR SLAB FOR PREFABRICATED BRIDGE, AND CONSTRUCTION METHOD OF HOLLOW FLOOR SLAB BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a construction method of a floor slab, capable of achieving concrete placing work by merely completing steps of manufacturing all major structures in a factory, carrying accurate products into a construction site, and inserting and binding distributing bars, and thus completing an accurate hollow slab bridge with a shortened work period and reduced labor power.;SOLUTION: The hollow floor slab unit for prefabricated bridge is composed of a main girder formed into a hollow shape by reinforcing bars, a group of reinforcing bars different from the reinforcing bars constituting the main girder, and a steel form covering the main girder and the group of reinforcing bars so as to form a space part between the group of reinforcing bars and the steel form, in which reinforcing steel is adhered to the steel form.;COPYRIGHT: (C)2010,JPO&INPIT
