Expansion joint shear wall reinforcing structure

The utility model relates to the technical field of building construction, in particular to an expansion joint shear wall reinforcing structure which comprises a tensioning screw, a connecting plate, a tensioning nut, a connecting piece, a formwork and a lining piece. The connecting plate is detachably connected with one template through a connecting piece; the tensioning screw rod penetrates through the connecting plate and the template; the tensioning nuts are in threaded connection with the tensioning screw rods, and one connecting plate in the tensioning nuts on the same tensioning screw rod and the other tensioning nut on the same tensioning screw rod directly or indirectly abut against the formwork; the two ends of the lining part abut against the templates respectively. According to the utility model, a stable pouring structure can be formed without fillers such as a high-strength foam extruded sheet and the like, and the manufacturing, the mounting and the dismounting are relatively convenient; the te
