PURPOSE: A bridge deck support structure is provided to allow assembly/disassembly work to be performed in an easy and convenient manner by using a fixing bracket and a tension bolt, while significantly reducing parts count for bridge deck support structure. CONSTITUTION: A bridge deck support structure comprises a cross beam(3) fixed between connecting boards(2); a fixing bracket(5) elongated in a horizontal direction along the cross beam, and which has a lower end fixed to both sides of the cross beam and an upper end where a plurality of stopper grooves(7) are formed at an equal spacing; an intermediate support(10) elongated in a horizontal direction and which is arranged between cross beams and connected to the connecting boards by a clamp(18); a tension bracket(12) a lower end of which is fixed to both sides of the intermediate support, and an upper end of which has a plurality of coupling grooves(14) formed at an equal spacing; and a plurality of tension bolts(19) arranged at an equal spacing between the cross beam and the intermediate support in such a manner that tension bolts are orthogonal to the cross beam and intermediate support, wherein tension bolts have both ends supported at the stopper grooves of the fixing bracket and coupling grooves of the tension bracket.
