Fixing Block for External Tendon Installation and Construction Method of Steel Box Girder Bridge using the same

摘要

The present invention relates to a fixing block having an improved structure so as to securely fix an external tendon, and a construction method of a steel box girder bridge capable of further improving the reduction efficiency of a bending mortent through the fixing block. The fixing block for external tendon installation according to the present invention for solving the above problems has a rectangular block shape in which a receiving space of a predetermined size is formed inside while the upper surface is opened, and a through hole of a predetermined diameter is formed on both sides in the longitudinal direction. of box case; a straight guide tube having a predetermined diameter that is installed inside the box case and horizontally connects the through hole; And one end is welded along the outer surface of the straight guide tube, the other end is characterized in that it comprises a plurality of reinforcing members having a predetermined length so as to be close to or in close contact with the inner surface of the box case.
