Continuous Beam Construction Structure of Prestressed Concrete Beam

摘要

And the subject innovation is more cost-effective beam cross-section design and construction is related to a PSC beam connecting structure according to the possible continuous bridge manner, the end junction's surface are opposed to each other doedoe installed on the bridge substructures, the abdomen and the lower portion of the beam end portions facing each other, was only out block upper flange portion other than the flange portion by being an upper flange portion connected to the space is formed and an upper flange portion connected to the space below the to be bonded to each other continuously in the adhesive incorporated in a spaced area between the lower flange portion and the abdominal joint surface of the beam the point resistance increasing amount of a cross-section beam; It is poured on the top flange connection area with a welding point of poured concrete; To introduce a compression prestress on the fulcrum portion, an upper flange portion connected to and pass through the space in the throttle direction, are spaced apart in both sides from the branch portion through the upper flange portion of the two beam anchorage both end portions in the preinstalled settling after stress branch unit serialization PC steel; And the slab concrete integral with the entire beam upper surface; and a.
