Urban underground passage main body structure steel bar positioning clamp

The utility model relates to the technical field of urban construction equipment, in particular to a steel bar positioning clamp for a main body structure of an urban underground passage. The technical problems that in the prior art, the structure construction quality is not effectively guaranteed, and the common quality of steel bar engineering is affected due to the fact that the distance between steel bars is manually measured and lofted according to a conventional process, and a protective layer cushion block is extremely prone to disturbing and damaging part of installed steel bars are solved. Comprising a long-strip-shaped square structure body. A plurality of positioning holes are formed in the width side of the square structure body; a reinforcing steel bar can penetrate through each positioning hole, so that the reinforcing steel bars are parallel; and a steel bar protection layer pedestal is arranged below the square structure body. According to the utility model, the installation spacing of the rei
