PURPOSE: A bridge repairing/reinforcing device using a truss member is provided to reinforce firmly by reinforcing load carrying capacity against load added to the center of a slab upper plate, to reduce repairing/reinforcing expenses by shorten the period for installing a truss structure and a reinforcing beam and to improve in appearance. CONSTITUTION: The bridge repairing/reinforcing device using a truss member comprises: a bearing bracket(11) fitted to the upper side of an abutment(1) and a pier supporting a slab upper plate(3); a truss member(5) fixed on the bearing bracket to locate an upper anchorage(6) formed on a part, where beam members are extended upward diagonally by facing each other, then coupled, above the slab upper plate(3) and fixed to the bearing bracket(11); a horizontal reinforcing beam(4) attached to the lower center of the slab upper plate(3) horizontally and provided with an anchorage with a hole on both ends; and a tension member(8) coupled to a hole formed on an upper anchorage(6) of a truss member(5), tensed upward from the upper anchorage(6) and fixed to the horizontal reinforcing beam(4).
