Then, according to the drawings, a first triangular frame and a first U-shaped placement groove 450 are used as the support system for the beam under-formwork 460. After fixing, the distance between the edge of the steel pipe 560 truss prestressed slab and the side formwork of the cast-in-place beam is measured to determine the required length of the second triangular frame under the cast-in-place slab. Step 2: After the second tripod is installed, it is connected and fixed along the Y direction using the connecting longitudinal rod 600. The double steel pipe 560 under the plate is used as the supporting keel under the plate. The double steel pipe 560 under the plate is fixed on the top support of the second tripod along the Y direction. Step 3: Adjust the height of the second tripod to ensure that the template surface is in horizontal contact with the 560 steel pipe truss prestressed plate, and insert the template under the 560 steel pipe truss prestressed plate.
