Title:
単径間及び多径間合成桁橋の施工法
Document Type and Number:
Japanese Patent JP3588325
Kind Code:
B2
Abstract:
Disclosed herein is a method of constructing simple and continuous composite bridges in which compressive stress is additionally introduced to an upper floor slab concrete in a negative moment region and the lower flange of a composite girder by lowering and lifting up end supports. The method includes the steps of providing first and second abutments, implanting a shape steel in said first abutment, simply resting a beam on said first and second abutments, connecting said shape steel to the lower flange of said beam, applying a connecting concrete to a portion ranging from an upper end of said beam first abutment to a neutral axis of said beam, lowering a support near said second abutment, applying a concrete to a portion ranging from an upper end of said connecting concrete to a bottom plate of said beam, applying a floor slab concrete to said beam, and lifting up the lowered support near said second abutment.
