[0002] In the traditional prefabrication process of concrete T-beams, the side forms of the T-beams need to be repeatedly demolded, molded and moved longitudinally. The traditional method mainly uses manual methods to repeatedly demold, mold and move longitudinally. This method requires a large number of workers to cooperate, with low work efficiency and high time and labor costs. At present, when prefabricated beam factories prefabricate beams and slabs, they mainly use hydraulic formwork systems for production. The hydraulic formwork system includes end forms, side forms and steel pedestals. Most of the end forms are fixed to the side forms by flange connections or fixed supports during production. When the beam length needs to be adjusted, only the flange or fixing mechanism needs to be remade, and the position of the end form will change accordingly, which can effectively avoid formwork waste.
