Possesses the precast make PC web size and its PC web size for the concrete bridge the prestressed concrete bridge

摘要

PROBLEM TO BE SOLVED: To provide a precast PC web for use in a concrete bridge, which is reduced in weight, has high shearing buckling strength, and enables to save construction labor and to shorten a construction period, and to provide a prestressed concrete bridge having the PC web. ;SOLUTION: A number of PC steel products 10 are longitudinally arranged at intervals in a bridge axial direction, and the steel products are embedded and fixed in concrete 8 in a state where the almost entire length of each PC steel product 10 is directly attached to the concrete. Thus, a precast prestressed concrete web 1 obtained by applying prestress to a reinforced concrete web 11 in the vertical direction by virtue of the PC steel products 10 which are directly attached to the concrete over the almost entire length thereof, is produced. Further, the prestressed concrete web members are arranged on both sides of a bridge with respect to a direction orthogonal to a bridge axial direction, and a number of the web members are serially arranged in the bridge axial direction.;COPYRIGHT: (C)2001,JPO
