When the ceiling elevation of gypsum board is the same as the beam bottom, gypsum board needs to pass through the beam bottom. The advantage of this is that there is no interface in the ceiling, which can effectively reduce the joint construction steps and reduce the risk of ceiling cracking. In addition, when the ceiling elevation needs to be treated and the beam is horizontal, the gypsum board should pass through the lower part and side of the beam. The joint of gypsum board is left on the side, and the bottom joint is not allowed to have a bottom plate, which can effectively reduce cracks and maintenance rate.
The corner at the top of the wooden keel of gypsum board ceiling is L-shaped to prevent cracks. When the wooden keel ceiling is sealed with gypsum board in the corner area, L-shaped whole plate construction is adopted. The bottom gypsum board is an L-shaped whole board at the corner, and the joints are made into a figure of eight, and then the joints are filled with gypsum powder, which can effectively prevent cracks.
Gypsum board should be made of materials with excellent fire resistance, weather resistance and water resistance, which can effectively prevent cracking caused by indoor and outdoor temperature changes and humidity changes. The material with good toughness, uniform foaming and full edge molding is better, which solves the cracking problem from the material point of view.
Decoration knowledge
When the exhibition hall is decorated, its function should be considered. Customers have been on their backs in the exhibition hall for a long time, so the decoration of the ceiling of the exhibition hall can not be ignored.
It is suggested that the exhibition hall should be decorated with integrated ceiling. Some exhibition hall decoration owners will think that the integrated ceiling is too expensive, and there will always be a misunderstanding that it is just a ceiling, how can it be so expensive? In fact, integrated ceiling and ceiling are different. The integrated ceiling decorated in the exhibition hall is not only the ceiling, but also many integrated appliances, such as lighting module, ventilation module and heating module.
