Precast beam reinforcement cage limiting device

The utility model belongs to the technical field of beams and slabs, and particularly relates to a precast beam steel reinforcement framework limiting device which comprises a pedestal, a mounting hole is formed in the lower end of the pedestal in the width direction of the pedestal, a telescopic device is arranged in the mounting hole and comprises a supporting bolt rod, and the length of the supporting bolt rod is adjusted according to the width of the pedestal. According to the precast beam steel reinforcement framework limiting device, by arranging the limiting device, steel reinforcement frameworks of different sizes can be limited, the height of a limiting plate and the height of a guide plate can be changed through lifting of the limiting plate in a limiting seat, and the limiting plate is inserted into a positioning hole through a positioning pin to fix the adjusted limiting plate; the technical problems that an existing beam plate steel reinforcement framework is installed on a pedestal through naked
