For the turnover mold shell, there are mainly three kinds of plastic (such as polypropylene) mold shell, glass fiber reinforced plastic mold shell and steel mold shell. The polypropylene mold shell has low cost, but the turnover rate is low and easy to be damaged. Large, high cost, FRP mold shell also has defects such as high cost and long processing and curing time in winter. That is, the above-mentioned mold shells made of a single material all have obvious defects. 2) There are nail holes on the bottom outer edge of the mold shell, and the mold shell is fixed on the rib beam formwork by steel nails through the nail holes. Cement putty. In winter construction, it takes a long time for the cement putty to dry. Under the combined action of the construction personnel, the vibration of the machine, and the binding load of the steel bars, the positioning steel nails cannot bear the increased load and then bend and deform, which makes the displacement of the formwork obvious and the concrete pouring. The phenomenon of slurry leakage is serious in the process.
