Bridge Deck System Using Precast Concrete Deck with Internal Tension

摘要

1. TECHNICAL FIELD OF THE INVENTION;Bridge deck system using precast concrete deck with internal tension.;2. The technical problem to be solved by the invention;In order to solve the problems caused by the joints existing in the bridges constructed with the precast concrete deck, the structure of the precast concrete bridge deck is improved, and the internal tension member is removed to enable the removal and replacement of the precast deck. Provided precast prestressed concrete bridge deck system.;3. Summary of Solution to Invention;It includes a plurality of precast concrete slabs and a plurality of tension members for tensioning the precast concrete slabs to each other, the grooves for forming a shear key at a predetermined interval is formed on the side that the precast concrete slabs are in contact with each other The groove has a predetermined inclination angle, depth and height, and is prestressed in the axial direction in order to maintain the adhesion between the joints between the precast concrete deck and to prevent leakage and cracks in the joints. do.;4. Important uses of the invention;Construction of bridge deck using precast prestressed concrete deck.
