6. A method for using a curved beam-slab formwork support system, using the curved beam-slab formwork support system according to claim 5, characterized in that: The following steps are involved: S1: Assemble the base structure and side panels: Place the base between two adjacent first brackets and connect them securely; connect the second brackets on both sides of the base to the corresponding first brackets to ensure a stable structure; place the first side panel on the support base, ensuring that the pins under the first side panel are accurately inserted into the positioning holes to achieve preliminary fixation of the side panel; S2: Install the top plate and preliminary splicing: Place the second top plate between the two first side plates, ensuring that its bottom is in close contact with the first side plates. Connect the entire top plate system by passing the connecting rod through the support base and the sliding block, and securely fasten the connecting rod with a nut ring. Place the two first top plates on either side of the second top plate and push them toward the center until the insert plates fit into the slots and the second insert rod fits into the sleeve rod, completing the initial splicing. S3: Adjust the arc and width: The second screw is rotated, and the second screw sleeves on both sides move away from each other, and the connecting rod is used to drive the second rotating seat and the second top plate to move downward, thereby adjusting the curvature between the second top plate and the first top plate; in this process, the sliding block moves along the connecting rod, stretching the spring, and at the same time driving the first insertion rod, the limit block, the first adjustment block, the second adjustment block and the extension plate to deform, and finally achieving the curvature adjustment of the first top plate; according to the actual width of the arc beam, the first insertion rod is pushed to move on the second top plate, so that the two second side plates are close to each other to a suitable position, and the bolts are tightened to fix the second side plates; S4: Adjust height and pour: By rotating the first screw sleeve to move upward on the first screw, the support seat and all the structures above it are driven to rise as a whole to reach the required height; use the ready-cut blocking plates to seal the gaps between the first adjustment block and the second adjustment block and between the first adjustment blocks; pour concrete in the space surrounded by the second top plate, the second side plate, the extension plate, the first top plate and the first side plate to complete the construction process of the entire structure.
