[0033] According to another aspect of the present invention, a method for using a plastic formwork for a combined counterfort based on a mortise and tenon structure is provided, including the following steps:

[0034] S01: Select appropriate long standard plates 7, short standard plates 11, corner plates 12 and corner columns 8 according to the size of the counterfort main body 5 to be poured;

[0035] S02: Adjacent formworks are mortised through the cooperation of the mortise grooves 13 and mortise tenons 14 to complete the preliminary splicing and assembly, and then the two end sealing plates 9 are placed and clamped at the door opening 3;

[0036] S03: Insert the bottom insertion plates 20 into the bottom slots 15 at equal intervals, and then cooperate with the iron nails 23 and gaskets 22 to fix the positioning plate 21 to the ground;

[0037] S04: Then, fasten the outer formwork 1 and the inner formwork 2 through the fastening device 4. Determine the distance between the clamping plates 17 on the two fixing buckles 16 according to the thickness of the counterfort main body 5. By pulling the moving plate 26, drive the adjusting block 10 to slide in the adjusting groove on the adjusting plate 18. After the adjustment is completed, fasten it through the adjusting bolt 25 cooperating with the adjusting hole 27 on the adjusting plate 18. At this time, turn down the fixing buckle 16 to drive the clamping plate 17 into the clamping groove 15 at the top to complete the fixation. Repeat the above steps to fasten the end sealing plate 9 and the outer formwork 1, and the end sealing plate 9 and the inner formwork 2 through the fastening device 4;

[0038] S05: At this time, after the formwork splicing and assembly are completed, pour the mold cavity through the pouring device, and then perform vibration compaction operation through the vibrating device. After solidification and shaping, turn each fixing buckle 16 one by one to drive the clamping plate 17 to rotate and move it out of the clamping groove 15 at the top, and then take out the iron nails 23 one by one, thereby losing the fastening of the formwork, and the subsequent demolding operation can be completed. After demolding, the counterfort main body 5 can be obtained.

[0039] In summary, the present utility model can facilitate the splicing and assembly of the formwork through the provided positioning component, and then can select and match appropriate formwork for assembly according to the specifications and dimensions of the poured counterfort main body 5, thereby facilitating subsequent pouring use and improving practicability. At the same time, it can facilitate subsequent demolding operations and facilitate repeated use next time; through the provided fixing device 6, it can facilitate the fixation of the formwork to the ground, etc., ensuring that there is no displacement during the pouring process, ensuring firmness, and ensuring the quality of pouring; through the provided fastening device ④, it can facilitate the fastening operation above the formwork, and cooperate with the fixing device 6 at the bottom end to ensure stability during use, avoid the occurrence of situations such as formwork bulging, and can also facilitate the adjustment of the length of the fastening device 4, thereby adapting to the fastening use of counterfort main bodies 5 with different thicknesses and improving practicability.
