PURPOSE: A tension control device of a membrane structure is provided to remarkably reduce installation and maintenance time by applying accurate tension to a membrane. CONSTITUTION: A tension control device of a membrane structure comprises a membrane plate(200), an electro-hydraulic cylinder(300), a tension sensor(101), and a power control unit(500). The membrane plate holds one side of a membrane(100). Both ends of the electro-hydraulic cylinder are connected to the membrane plate and a post(400) through pivots. A DC motor, a hydraulic pump, a valve, and a cylinder are integrated in the electro-hydraulic cylinder. The tension sensor is attached on the membrane and measures tension. The power control unit supplies power to the electro-hydraulic cylinder and automatically controls the electro-hydraulic cylinder.
