The PC floor system unit null which is used for the delivery aerial construction method and its construction method of the floor system bridge

摘要

PURPOSE: To make it possible to construct PC floor slab units easily, surely, economically and safely. ;CONSTITUTION: In the case PC floor slab units 1 are delivered along cables 4 constructed between abutments, tensile force of a delivery wire 43 and tensile force of a holding wire 40 are adjusted to prevent the action of tensile force between the PC floor slab units, tongue and groove unevenness between the PC floor slab units is dissolved and, at the same time, constructing jigs 14 bearing unit main bodies 2 on the cables 4 in a movable manner are provided on the unit main bodies 2. Friction between the PC floor slab units 1 and cables 4 is reduced, and the construction of the PC floor slab units is carried out easily, surely, economically and safely by delivering smoothly the PC floor slab units 1 to construct.;COPYRIGHT: (C)1994,JPO
