The outer top of the support seat is provided with a positioning piece for positioning the first side plate; a sliding block corresponding to the second screw sleeve is detachably provided in the support seat, and the top of the sliding block is fixedly connected to the corresponding second screw sleeve for supporting the second screw sleeve.

7. The curved beam and slab formwork support system according to claim 6, characterized in that: The positioning member includes two positioning holes opened on the top of the support seat, and the bottom of the first side plate is fixedly provided with a limiting column corresponding to the positioning holes, and two adjacent first side plates on the same side are both located on the support seat.

8. The curved beam and slab formwork support system according to claim 7, characterized in that: Two connecting rods are penetrated on one side of the support seat, and the outer wall thread sleeve of the connecting rod is provided with a nut ring that abuts against the outer side of the support seat and is used to fix the connecting rod. The sliding block is slidably arranged on the corresponding second screw rod, and the outer wall sleeve of the second screw rod is provided with a spring, and the two ends of the spring are respectively fixedly connected to the inner wall of one side of the support seat and one side of the sliding block.

9. The curved beam and slab formwork support system according to claim 8, characterized in that: A first screw is rotatably provided on the top of the base, a first screw sleeve is threadedly provided on the outer wall of the first screw, and the support seat is fixedly provided on the top of the first screw sleeve.

10. A method for using a curved beam-slab formwork support system, using a curved beam-slab formwork support system according to any one of claims 1 to 9, 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 firmly; connect the second brackets on both sides of the base with the corresponding first brackets to ensure a stable structure; place the first side panel on the support seat, and ensure that the pin under the first side panel is accurately inserted into the positioning hole to achieve preliminary fixation of the side panel; S2: Installation of 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; use a connecting rod to pass through the support seat and the sliding block, and firmly fix the connecting rod with a nut ring to connect the entire top plate system; place the two first top plates on both sides of the second top plate, and push them toward the center until the plug plate is inserted into the slot and the second plug rod is inserted into the sleeve rod to complete the preliminary splicing; S3: Adjust the arc and width: The second screw rod 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, so as to adjust the curvature between the second top plate and the first top plate; in this process, the sliding block moves along the connecting rod, stretches the spring, and at the same time drives the first plug rod, the limit block, the first adjustment block, the second adjustment block and the extension plate to deform, so as to finally adjust the curvature of the first top plate; according to the actual width of the arc beam, the first plug 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 rod, the support seat and all the structures above are driven to rise as a whole to reach the required height; the gap between the first adjustment block and the second adjustment block and between the first adjustment blocks are sealed with ready-made blocking plates; concrete is poured 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.
