The invention discloses an assembled monolithic two-sided overlapped shear wall structure. The assembled monolithic two-sided overlapped shear wall structure comprises a first overlapped template, a second overlapped template and cast concrete, wherein the first overlapped template comprises a first concrete body, a first rebar net framework and multiple first truss bars; the second overlapped template comprises a second concrete body, a second rebar net framework and multiple second truss bars; the cast concrete is arranged between the first concrete body and the second concrete body, and isintegrated with the first concrete body and the second concrete body; the first truss bars are arranged at the portion beyond the first concrete body, the second truss bars are arranged at the portionbeyond the second concrete body, and the first truss bars and the second truss bars are overlapped and spaced. The assembled monolithic two-sided overlapped shear wall structure is maintained and formed at a time, the energy consumption is low, locating bolts are reusable, reserved holes are easy to process, two-sided overlapped template plane production is conducted, vertical pairing is conducted, the standardization degree is higher, bars are produced from sides and peripheries, connection of the bars with surrounding components is facilitated, and the applicable range is larger.
