<P>PROBLEM TO BE SOLVED: To provide a bridge joint structure which integrates a deck slab and a deck slab adjacent part together via a composite body consisting of a connection member and a restraining member to make an interlocking structure body allowing a bridge girder formed in this manner and a bridge girder neighboring material to behave integrally and displacively. <P>SOLUTION: A bridge joint 20 is a composite body composed of a connection member 21 and a restraining member 22 which are erected astride between a deck slab 5 and an abutment parapet 8. The connection member 21 is formed of a reinforcement 21 which connects the deck slab 5 to the abutment parapet 8, and the restraining member 22 is formed of post-placed concrete which joins the deck slab 5 and the abutment parapet 8 together in a state that the connection member 21 is covered by and restrained in the restraining member 22. An interlocking structure body allows an abutment to behave integrally and displacively interlocking with displacement behavior of the bridge girder due to integration of the bridge girder and the abutment via the bridge joint 20, and can absorb expansive/contractive displacement and rotational displacement of the girder end of the bridge girder as a whole displacement behavior of the interlocking structure body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
