<p><P>PROBLEM TO BE SOLVED: To provide a superstructure used for constructing a bridge, with which the construction is facilitated and a high-strength bridge can be constructed. <P>SOLUTION: A superstructure 101 is provided which is obtained by coupling a pile member, a main girder 111, a lateral girder 113 and a pile head fixing member 115 having a cylindrical part through which the pile member can be inserted. The main girder 111 and the lateral girder 113 are coupled to a side face of the pile head fixing member 115 in such a manner that centers of the cylindrical parts of all the pile head fixing members 115 are positioned on a cross section of a central axis of the main girder 111 in a length direction and a central axis of the lateral girder 113 in a length direction. Therefore, the main girder 111 and the lateral girder 113 are disposed in a rectangle shape, in a ladder shape or in a U shape, an upper surface of the pile head fixing member 115 is brought into contact with a floor slab disposed on the superstructure 101 directly or indirectly via a canopy closing the upper surface of the pile head fixing member 115, and the upper surface of the pile head fixing member 115 becomes vertical to the central axis of the pile member when inserted through the pile head fixing member 115. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
