According to the conventional construction process of the tapestry brick ceiling: the method comprises the steps of supporting a blade template → binding steel bars → pouring concrete → removing the template → plastering a ceiling → pasting tiles, and the construction period is long.

3, dome tile process quality control: the six hyperbolic leaf surfaces have large area, large radian, large height difference and complex patterns, and the problems that the pattern forming effect and the facing bricks fall off cannot be effectively controlled according to the conventional facing brick construction process are solved.

4, the construction safety and durability of the facing brick inversion method: the new process has no reference experience, and the process flow from the selection of parameters of the jointing slurry to the construction must be determined through experiments so as to ensure the safety and the durability of the whole decorative finish layer.
