JOINT STRUCTURE BETWEEN A PRECAST CONCRETE BEAM AND A CONCRETE DECK PLATE IN A PRECAST COMPOSITE BRIDGE CAPABLE OF SECURING SHEAR CAPACITY OF HORIZONTAL STRENGTH, AND HEIGHTENING THE WORKABILITY ON PIPE ARRANGEMENT OF A CONCRETE DECK PLATE AND THE EFFICIENCY ON PLACING CONCRETE

摘要

PURPOSE: A joint structure between a precast concrete beam and a concrete deck plate in a precast composite bridge is provided to secure the equal or above transfer of horizontal strength in comparison with the arrangement of dowels, and to heighten workability on arranging pipes on a concrete deck plate and placing concrete. CONSTITUTION: In a precast composite bridge composed of precast concrete beams(1) arranged in a row and applied with prestress and a concrete deck plate(2) constructed between adjacent precast concrete beams(1) and on a precast concrete beam(1), the joint structure between a precast concrete beam and a concrete deck plate in a precast composite bridge comprises the steps of arranging joint plates(3) having openings axially over a precast concrete beam(1) and a concrete deck plate(2), inserting a reinforcing bar(4) which is arranged in the precast concrete beam(1) to a lower opening of the joint plate(3) and inserting a reinforcing bar(5) which is arranged in the precast concrete beam(1) to an upper opening of the joint plate(3).
