PRESTRESSED CONCRETE COMPOSITE GIRDER

摘要

PURPOSE: A PSC composite beam for integrally manufacturing a bridge deck and a cross beam is provided to reduce the crack incidence by making the lower part of a beam at the compression stress state and to shorten the construction period by simplifying the process. CONSTITUTION: A PSC composite beam(100) for integrally manufacturing a bridge deck and a cross beam is composed of a bridge deck which is integrally formed in the upper part, cross beams which are integrally formed in both sides to be projected, and a horizontal tendon which is each inserted into a horizontal post-tensioning sheath pipe of a bridge deck and a cross beam to apply the horizontal prestress.
