The invention relates to a roadway support structure adopting matching of a truss and U-shaped steel. According to the roadway support structure, the problems of poor independent support effect and potential safety hazard of a U-shaped steel support can be effectively solved. The roadway support structure comprises the U-shaped steel, clamp seats, hinged joints, hinged bolts, a chord member and web members, wherein the hinged joints at the upper parts of the web members are connected with the U-shaped steel through the clamp seats, and the hinged joints at the lower parts of the web members are connected with the chord member through the clamp seats. The roadway support structure is convenient to use, easy to mount and good in connecting effect, occupies small roadway space, can replace and save other unnecessary materials, brings great convenience for underground safety and production, and enables the support to be stable and effective.
