<p><P>PROBLEM TO BE SOLVED: To provide a bridge on which a continuous pavement without an expansion device, etc. can be formed over a multi-span and which can be constructed economically in a short construction period. <P>SOLUTION: A bridge is formed by arranging a plurality of single span frame structures 10, each of which comprises two bridge piers 1, 2 made of concrete and a concrete girder section 3 laid on the bridge piers, the piers and the girder section being integrally connected, in the axial direction of the girder section. A predetermined interval is provided between end surfaces of girder sections of two adjacent frame structures, a connection floor slab 4 is laid between the girder sections, and both ends of the connection floor slab are fixed to the girder sections. The connection floor slab is reinforced by reinforcing-bars 21, 22 arranged such that tensile force can be transmitted between the reinforcing-bars and reinforcements embedded in the girder sections, and is formed such that its top face is substantially as high as the top face of the girder section. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
