The construction of shear walls on both sides of the expansion joints is the key point and difficulty in the construction of the main structure. Since the expansion joint is narrow, it is impossible to set up scaffolding, resulting in workers having no reliable construction platform during construction, which poses a great safety hazard. At the same time, it is difficult for workers to install and remove the shear wall formwork, which can easily cause quality problems in the shear wall and fail to meet the construction requirements. Therefore, it is necessary to design a expansion joint position operation platform device and an installation method thereof. Summary of the invention

[0003] The purpose of the present invention is to provide a deformation joint position operation platform device and its installation method, so as to solve the technical problems of the existing deformation joint position operation being difficult and unsafe.
