EXECUTION METHOD OF MULTI-SPAN CONTINUOUS STEEL GIRDER WITH REINFORCED CONCRETE FLOOR SLAB

摘要

PURPOSE: To improve materials and the efficiency of processes by enabling the construction of an RC floor slab even from one direction. ;CONSTITUTION: Cast-in-place RC floor slabs 4 are placed on a top face and an intermediate section is borne by piers 3a, 3b... in a steel girder 1. Clamping members 6a, 6b are provided jointly to temporary posts 5a, 5b used when the steel girder 1 is built, and connected to the steel girder 1 before the RC floor slabs 4 are constructed and pulled down up to height at the time of completion, and the floor slabs are erected successively from the pier 2a side. The steel girder 1 in a section, in which concrete is not placed, is held in height at the time of completion at all times at that time. When the floor slabs are constructed while crossing the piers 3a, tensile load working to the temporary posts 5a, 5b, etc., is reduced successively. Height may also be adjusted by PC steel materials 8a, 8b... in place of the temporary posts.;COPYRIGHT: (C)1996,JPO
