Cast-in-place beam flange plate formwork supporting device

The utility model discloses a cast-in-place beam flange plate formwork supporting device which is formed by sequentially connecting a certain number of formwork supporting units side by side, and each formwork supporting unit comprises a main framework, a beam bottom arc steel plate, a beam side linear section, a beam side arc section and a flange plate lower linear section. A combined system of the wooden formwork, the bakelite plate and the wooden framework is adopted, the wooden formwork is used for machining the linear section, the bakelite plate is used for machining the curve part, and the square timber is used as the framework for supporting, so that the problems that a traditional steel formwork is long in production period, large in dead weight, high in cost, inconvenient to transport, large in safety risk, low in work efficiency and the like are solved; and the problems that a wood template cannot be bent and a special-shaped structure cannot be processed are solved.
