The time of production gypsum core model, effectively shorten the duration；
2, gypsum core model is embedded in cast-in-place coagulation by cross reinforcing, waling, baseplate reinforcing bar and top rebars respectively
In soil, gypsum core model floating can be avoided, drive briquetting to shake concrete by vibration motor, make concrete inner structure more
Closely, concrete will not expand upwards, and gypsum core model will not float, and by pre-buried steel wire connector in gypsum core model
It is interior, facilitate reinforcing bar to connect, saves the operating time.
