Therefore, the metal grille and mineral wool board must be handled well, between the ceiling and the ceiling. Vertical or parallel relationship between walls and columns. In this regard, the relevant axis should be measured to the facade of the wall pillars, and the base line should be pulled to find the rules for plastering, so as to ensure that the wall surface is parallel to the axis and two Adjacent faces are perpendicular to each other. This serves as a reference plane for the ceiling plane position.
3. Girder ceiling arching form and arching height: This project is not suitable for arching because of the long longitudinal dimension. The arching should be in the short-term north-south direction. The arching height can be about 1/200 of the 8m column distance.
