<P>PROBLEM TO BE SOLVED: To provide a bridge joint structure in a form of a linked structure in which a bridge girder and a bridge girder adjacent object can perform integrated displacement behavior by integrating a floor slab and a floor slab adjacent part through a composite body including a connecting member and a restraining member. <P>SOLUTION: A bridge joint 20 is a composite body including a connecting member 21 and a restraining member 22 disposed over a floor slab 5 and an abutment parapet 8; the connecting member 21 is formed of a reinforcing bar 21 connecting the floor slab 5 and the abutment parapet 8; and the restraining member 22 is formed of site-placed concrete or site-placed mortar for connecting the floor slab 5 and the abutment parapet 8 in the state of enclosing and restraining the connecting member 21. In the linked structure, the bridge girder and an abutment through the bridge joint 20 are integrated so that the abutment can be integrally displaced in linkage with the displacement behavior of the bridge girder, and thereby extension/contraction displacement and rotary displacement of a girder end of the bridge girder are reduced into the overall displacement behavior of the linked structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
